GMC Sierra Reviews

DO NOT PURCHASE GM PRODUCTS. I purchase a new 2020 GMC Sierra 1500 AT4 a month ago and it is now in the shop for the second time. It has been in the shop for over two weeks and in all, it has been in the shop for roughly three of the four weeks I have owned the truck. Since I need my truck to work, I am now losing income while at the same time I am making payments on a truck that is in the shop. To make matters worse, the GM Corporation has repeatedly cancelled my parts order with no explanation as to why it did so. Worst of all, despite repeated requests, the GM Corporation will not do anything to make me whole in terms of the financial losses I have incurred as the result of the corporation's poor quality control.

Brand new 70,000 dollar Gmc Sierra Denali 3700 miles. Loud lifter noise. Never made it to the first oil change. Now they have to tear down the whole engine. Been a GM man my whole life. Saved and worked to get this truck and this is how it is. Maybe it’s time to change.

We are retired and have had superb service from our 2014 GMC Sierra extended cab 4x4 that was purchased new. Recently completed a 5000 mi road trip through Canada over some rough roads. The truck is quiet and comfortable and has had no mechanical issues. Very satisfied with our purchase.

2003 GMC Sierra - Bad Brakes. Been in two rear collisions because the brakes are weak, had every brake component replaced including lines and hoses and brakes still feel the same. I've read from many others that this is an issue they tried to blame on salty roads rusting the lines but I can assure you even with brand new lines they are no different. Truck sits in the driveway and I'll be buying a Dodge Ram when it comes to my next truck because this one I'm scared to drive and I have thousands of dollars invested in keeping it maintained and replacing poorly designed parts that were redesigned after everyone had issues at our expense.

At 9600 miles my 6.2 motor blew up and almost ended my life while traveling at highway speed on cruise control, in heavy traffic, on the NYS Thruway. Luckily it didn't lock up or I might not have survived. 18 days later a new 6.2 engine direct from the factory was installed. The very day I picked it up, the second stop I made it wouldn't start. 34 consecutive days later without my truck, I finally get it back after starter was replaced, fuel lines, fuel pump, and cam actuator. 3 days later, truck stalls out again at highway speeds and won't start!! GM does nothing but refer me to my dealer who have been great. I had a start issue with my 2017 Chevy Silverado at 30k (4 different times), never resolved. Why I'm here. Why am I here??!! New 2019 loaner truck with 2k on it and the service 4WD light is on!!! Been GM for over 30 years and I don't have a choice but to move on from all this. BUYER BEWARE!!! Oh, PS, truck is still in shop. GM won't even talk to me anymore.

I bought a 2008 Sierra new in 2008. It now has 163000 mi on it. A ticking noise developed on acceleration. I took it to the dealer and was told it had a bad cam. $5300 to repair or $7750 for a new engine. They charged me $139 for this bogus info. I knew it did not have a bad cam. I took it to an independent service dealer. He told me it had a faulty active fuel management.. (runs between 4 and 8 cylinders). Told me to disable it. He did not charge me for this info. I disabled it and it runs better than new. Talked to GM customer service, they didn't do anything except lip service. I just wanted my $139 back for telling me erroneous diagnose. In the last 52 years I have bought 22 GM vehicles. Never again!

I bought my 2014 GMC Sierra on 2017 with 20k miles on it. Within a month I noticed that the paint was peeling in the bed of the truck. I bought it to the dealership and because it was still under warranty they repainted it for me. About six month later I notice the paint was bubbling off the doors. Took it back to the dealership and neither the dealership or GMC would assume any responsibility financially. (Warranty was expired). I had to spend over $1,000 to get my doors repainted. Within several month of me getting the doors done the paint is bubbling off of the roof and around my windows. I know there are many people who are having this same problem with this particular year GMC and Chevy.

Have had new GM trucks since 2010. A new one every year, brand new truck drove off lot and Have had the 8 sp shutter in trans ever since, driver's seat has a bad spring which makes terrible noise. Finally got fed up now. Has 5000 miles. GM will not warranty and repair seat, reprogrammed trans and made the problem worse. GM is losing a customer. I'm going to go to a Ford. It's sad when you buy a truck that cost almost 60k and this is the quality of product you get.

I was nearly killed on the job as an Inspector on a Highway project when I tried to pull out of my lane closure and the drive train and/or brakes locked up on me after accelerating above 5 mph. The dealer is unable to find and fix the issue. Don't drive any of the 2019 GMC pickups for extended periods and/or leave in idle. Unfortunately for me for my job I need to do just that. I am now terrified to drive my truck and it is only a matter of time before I am involved in a serious accident.

I bought a 54K GMC Sierra Denali 1500 thinking that it would last for a while without any issues. Boy I was wrong. I had an engine light on and took it the dealer to repair. They told me that it was the fuel injectors and it wasn’t on my 100000 powertrain or the emission warranty. It is going to cost me $1,600 to repair. I only have 62K miles on it and I take it in religiously for routine maintenance. What’s next? The engine? I should have did more research on GMC products.

Bought 2017 GMC Sierra Denali and had nothing but problems with transmission. They changed transmission fluid, it didn’t help. I have taken it to the dealer 4 times. They said it is a software problem but nothing has help. My truck still under warranty and I am very seriously of getting me an Attorney under the Lemon Law.

I wouldn't buy on until they fix their junk. A trailer disconnect Lane departure Lane assist all this comes on when you're driving on a road. This only happens when it's cold outside when the temperature is below 20 degrees.

8 Speed transmission hesitation since new. Several trips to the dealer. 3 transmission flushes now. Replaced torque converter, shift module and did some valve body work. Still no change. Dealer suggested that I trade my 2017 Sierra in on a 2018 model. I’ve suggested that GM just replace the transmission. I’m sure GMC will just “wash their hands” on this and I’ll be stuck with it.

GM customer care came up with a "resolution" by offering me 10% off the repair to fix their mistake and sheepishly apologized for the "unexpected cost".

Purchased a 2014 GMC Sierra with 82K Miles. Loved the Truck and options in it. However, shortly after purchase I noticed when truck was rolling in gear transmission would shift into or out of gear very hard. Took to GMC dealer they checked out and said everything was normal. This is not normal, never owned a vehicle that shifts so hard you can feel it. Truck has recently started to vibrate around 40 MPH, will take back to GMC dealer once again. Attention Buyers, there are tons of complaints out there about related issues. Do your homework first...

The starter location is worthless. I have been working on trying to change it for 6 hours and cant get the damn thing off. Whoever did this has ruined me for GMC Duramax. I will be selling this truck and I will never buy another one in my life. I wouldn't take one for free. I'm so angry I just wanna set the truck on fire and watch it die. GM is absolutely worthless.

I leased a 2017 Sierra Denali about 1.5 years ago. The truck has been great so far at 18500 miles. Last week the front camera went out (runs intellibeam light function and low speed collision system). It is being replaced under warranty as we speak. I have had several GM trucks and SUVs since 2001, and they have all been reliable, mostly well built vehicles. The magnetic ride control on the Denali is very nice. The interior fit of the truck is also pretty good except for the plastic wood trim. On a $55000 truck it should be real wood. I have also never been able to get the wireless charger in the console to work consistently, but apparently others do not have this problem.

NEVER BUY A GMC, If you ever have a problem or need help it may take a week or more to even get in especially if you need a loaner. Stick with a better option this company is the worst when you need help on your new car. I will never buy a GMC again, worst service ever!

I have owned my 2014 GMC Sierra SLE for about 2 years now and have had nothing but problems with the A/C. I live in California and A/C is a must. I have already replaced the A/C air compressor line for $600. After that was fixed the A/C condenser went out and I have been driving around all Summer with my Windows down to keep cool in this California heat. I was told it would be $1200 to replace the condenser plus labor. My GM certified mechanic is telling me he runs into this problem with these models all the time and that I should reach out to GMC to get some assistance on the repair.

GMC 2012 Sierra has been amazing. It has an excellent performance rating and on top of everything else we love the style, color, make and model of it. We love the TV and the extra seating in the back. It fits our daughter and our dogs comfortably for a road trip! The heating/air conditioning in the back is great too! overall, It is an amazing truck and we love it a lot! It has been a great hot car for our family!

GMC Sierra is an excellent vehicle with his sensors of getting out of your lane or the front and back sensors save you from having an accident or alerts you before and you can avoid having an accident. WiFi is an awesome thing that you have in this vehicle because if you're still in school you can be in the vehicle submitting assignments. Also the navigation system helps you a lot to get to one place and other. While I love my Sierra, I don't like that thing you step on to get on the truck because they have a plastic thing that with time it cracks.

My experience with my GMC Sierra 2500 has been good. It is a truck that can handle all the terrains, from the daily life of the city to a rocky or mountain terrain. It has a power that yields according to the use. Maintenance costs are balanced, no surprises in terms of repairs. I consider it an incredible option for men in the house. I like how spacious it is. That allows me to move loads without worrying that the shock absorbers can be mistreated. I also like how tall it is. It's a great option to drive safe and with style. But I do not like that it is not easy for me to park it in certain places. It takes up a lot of space and sometimes it is difficult to find a place for example in the shopping centers.

The GMC Sierra 1500 has good dependability. It has safety options included, as well as radio, OnStar and backup assist. Love the color and interior options. Love the sleek design too. It has no road noise, okay gas mileage and I'm happy with dealership. But it has a bit boxy body. I would like the hood/top area not be so straight lined, rather have a slope type design like the 2000s models.

I like that it's a safe vehicle. I feel comfortable driving it and I liked the rear view camera. I had a decent experience with the truck and we've put a lot of miles on it. But the service department where we get the truck's oil changed at isn't very good at doing their job. Also, it's a huge vehicle so it's hard to back it into parking spaces. And there's not enough leg room in the back seat. The GPS isn't very precise and the car detailing should be included once a year as part of their vehicle service package. The WiFi should be included and not have to pay extra for it.

I chose this vehicle because of the old fashion look, and it is not sluggish if a speed is needed. It has smooth ride and very dependable. Drove from the West Coast to the East Coast 4 times. Also from AZ to WA state 4 times. Never any problems. It has low maintenance, lots of leg room, trailer gear works great too. The color was important to us and the purchase price was on point. But the turn signal lights in front collects water/moisture. Replacing bulb often. I dislike the grill front and did not like the wheel size. After a few months, I purchased larger wheels. In addition, a bit of factory tinted glass could be used at the front windshield.

5.3 L V8 Active Fuel Management - Bought a 2012 GMC Sierra Z71 Crew cab in November 2017 with 60,000 miles on it. Cannot put into words how happy we were to buy this truck. Worked very hard to get us out of the old, falling apart Chevy. Paid $27,000 for this truck just 6 months ago and now it's worth next to nothing. There was something wrong with it from the start, it would constantly go from V4 to V8 within seconds. Loud vibration drone sound when it would be in V4 for all of 15 to 30 seconds then back into V8. Was consuming over a quart of oil between oil changes. TICK, TICK, TICK I know lifter noise when I hear it. Was told this was "Normal".

We have used the 2004.5 GMC 2500hd to tow our heavy 5th wheel RV over 45,000 miles and it has performed flawlessly, never had any issues. Replaced original front brakes at 130,000 miles due to a warped rotor and replaced the glow plug controller which failed but did not have any effect on starting.

The GMC Sierra's trim is cheap and poorly put together, water leaks into the door frames every time it rains, all the speakers either don't work or work sporadically. Key fob stopped working after only 5 years.

I had to get my transmission rebuilt on my 2014 GMC Sierra at 120,000 miles. Not a huge issue, but I keep meticulous records on my vehicles. I also had a 2001 GMC Sierra that had the same issue at about 108,000 miles. I'm noticing a pattern here, and will probably never own another GMC. All the service work was done at the GMC dealership I purchased the vehicle at. This does not mean anything to GMC. Simply a buyer beware to anyone considering purchasing one of these vehicles.

1996 GMC Sierra - Truck frame is so rusted that it looks like the truck has been totaled. Bed has been replaced, but the frame is not repairable. The brake lines are rusted and brakes have went out and caused me to have to drive into a ditch to avoid a wreck with another vehicle. This is insane and I have seen several other GM trucks that look horrible with the amount of rust that you can see, I have also seen older GM trucks that look like the bed is sitting at an angle due to the rusted frame. GM should be ashamed.

2017 GMC Sierra 2500 pick up truck: My truck goes from 2 wheel to 4 wheel drive (or vice versa) on its own. The radio changes stations on its own. Goes from Sirius to FM on its own. Radio display screen and steering wheel display screen change - screen shows miles per hour and then suddenly changes to what's playing on the radio. My telephone will work sometimes/sometimes not while connected to Bluetooth. Heaters changes options on its own. Right turn signal goes from normal to superfast on its own. Periodically the radio doesn't go back on after phone is disconnected - must manually turn on. GMC says it can not replicate and has "engineers" checking it - so far no results - I hardly ever have my truck since someone is always checking it at GMC. Any ideas? Anybody else having these problems? Help! Thanks!

Bought my truck (2016 Sierra 1500 SLT with 6.2) new December 26, 2015. LOVED the truck, bought the truck. On way home from dealership I noticed noises from the transmission. Took it back next day and told have to drive for 2,000+ miles so the vehicle learns me and how I drive. OK so 2,000 hits back to the dealership, told they can't find anything wrong. Keep driving does it worse and also now clunks when goes in reverse. Take back to dealership again and told they have to reprogram and they need for a whole day to do this. No problem. Pick up and does immediately in the dealership parking lot. Park again and go back in. Told I have to drive again for 2,000 miles so I do. Does worse so take back again, told nothing they can do. That's it's operating as intended... really?

Warning for anyone looking to buy a 2015 Sierra Denali... both the transmission and 6.2 engine are junk. Just had my litters and camshaft replaced at 140,000 miles. I have babied this truck from day 1. GMC doesn't know why? All services have been done at the required frequency. Transmission has never shifted right from day one. Dealer says that's just the way those trucks shift. Pretty Sad. I have always been a Chevy and GMC fan. Time to switch to a Dodge.

A beautiful truck (used GMC 3500 Sierra crew cab) to look at but it is still in the shop. First break down was the TCM during the HURRICANE. We were evacuating from South Texas. It broke down about 60 miles from the coast. I limped it to a Motel and we stayed there for 3 days until the storm had subsided. Finally got it home then a wrecker picked it up there. Then two months after that the DEP system went out and it is still in the shop even after a new tank and line were installed. Damn thing goes into limp mode after being driven about 10 miles. I will never own another GMC product. They are JUNK and that DEP system is the biggest piece of junk ever thought of. I have already spent $2000.00 dollars on it and have had it only one year and drove it maybe two months of that. I will never buy or own a General Motors Product again. Because they do not give a DAMN about their customers.

I have owned a 2015 and a 2016 GMC 3500 one ton Denali. I've had nothing but problems with both vehicles. I purchased these top of the line trucks because downtime in my business will put me out of business. My current 2016 Denali has 24,000 miles on it and the HMI modules has gone bad. We spent a whole day at Hart GMC in Salem, VA to have the problem diagnosed and it finally was around 2:30. We were supposed to leave town on Monday but had to stay in town until Tuesday when the HMI module would be in. It's almost a week later and we have never received a call from the Dealership. We called several times and were told to call back later. We contacted GMC customer service 10 times and no one will do anything about this. We finally had to leave town to get back to our business. We've lost about $5000.00 because of the huge delay leaving town.

I bought a 2014 Sierra SLT 1500 in Nov of 2014 and at 50k miles it is just falling apart. It has been riddled with nothing but problems and GMC customer support does not care at all about my experience. They take their sweet time to get back to you and when I ask to talk to a manager the customer service rep says there's no one else that I can talk to. To give you an idea of what I've been through here's a timeline of the issues that have plagued the truck: 6/13/15 - Passenger sunshade fell apart. 12/8/15 - A/C doesn't function correctly, 4WD Recall, Front window won't go up. 8/10/16 - Seat belt tensioner cable went out. 10/6/16 - A/C compressor hose went out. 10/16 - Recall on Air Bag SDM - Big Safety Issue. 10/31/16 - Catalytic Converter light came on, transmission locks up.

From day one the transmission bangs/slams noise just rolling slow out of driveway or in parking lots. Truck only has 1300 miles on it and the dealer has been notified each time and was brought in twice and they say the same thing, "That's the way it is" and there is nothing they can do until GM Corporation says there is a recall. They need more people to complain soon before everyone's warranty runs out. My GMC Sierra only has 1300 miles on it now after coming home from the dealership service dept. Again today 12/28/2017. The vehicle was purchased October 4th, 2017 and today's date is Oct. 28, 2017. This dealership seems to be very nice but the GM Corp. Must tell them what to say.

I leased a 2016 GMC Sierra and was told that they were nice trucks. We have 18,500 miles on it and it is a pile of junk. When it shifts from V4 to V8 it shutters and then clunks. It also chirps when it changes from V8 to V4. We have taken it into the dealership and they told us it needed a muffler clamp and then replaced that. So we continue to drive it because it is a leased vehicle but it keeps doing it and is very annoying. In reading all of the complaints everyone's response is the same as ours... They can't fix it because that is normal. How can clunking be normal? However I am stuck with this horrible truck for 2 more years and I am not sure that I will ever buy another GM product since they can't help me with this one.

My new 2016 GMC Sierra with 8000 miles and the brakes failed while driving. I am alive to write this review. Without a brake light notice, my brakes completely stopped working. I was in a street lane, able to pull into a parking lot and roll to a stop. GMC towed and serviced. I was told it was a braking sensor, which was repaired and replaced with the same sensor. The service manager gave me no guarantees this would not happen again. How does one drive with any confidence? You don't! I could have been pulling my horse trailer and we would all be dead.

2017 GMC 3500HD Denali (new) 300 miles: Purchased this top of the line 65,000 dollar truck last Friday night 7/18/17 from a dealership about 2 hours away from my home in Branson Mo. Drove the truck home, shut it off and the next morning would not run. So it sat in the driveway until Monday morning which I had to have it towed to a local dealership and they looked it over and tell me they need to order this part which seems to be the turbo assembly. Was told they will ship it in overnight. Ok this will not be too bad. Well it's now Friday 5 days later and to this date they cannot tell me when this part will come in. NO timeline at all, they just do not know???

I had a 2015 Dodge Ram and loved it but local dealer wouldn't work with me so I went to Varney GMC in Bangor and next thing I know I'm leasing a 2017 GMC Sierra 4 Elevation more than I wanted to and longer than I would have liked. Anyway less than a month after lease I noticed the truck pulling to the left and having a little shake so I went to dealer and they put in the alignment machine and said nothing was wrong.

I bought a brand new 2017 GMC Sierra 2500hd 5 months ago. From the first month, I had a rattle and shaking feel at under 40mph. Then at 6,000 miles, the transfer case and rear differential went bad. I took it to the Simi Valley GMC dealer for repair. They drive it and said they can't replicate the issue and didn't fix anything. Then at 6,900 miles it got so bad and when I took it, they realized all the issues and started the process with GMC warranty.

I can't believe the lack of support a customer can received from GMC. As a lot of you know or will soon find out that your A/C system is compromised and will soon fail. All trucks from 2016 to 2013 and Thierry solution for the problem is make a factory back order till they can figure out how to fix this growing problem. Meanwhile we are left to pay for our loans and sweat while the people that are standing in the way are collecting our cash and enjoying the air conditioned rides!!!

I recently purchased a 2017 GMC Sierra in March. Within a week of the purchase the vehicle produced a vibration at all speeds above 40 mph. The truck was in the shop for over 20 days of the two months that I have owned it with three different dealerships confirming it has an issue. GM dispatched one of their field engineers and I was told my truck was "operating as designed". I told them it was a safety issue as it makes me physically ill while driving. The rep ignored this and basically the only thing I was told to do was go through the lemon law process.

I purchased my 2015 GMC Sierra 1500 SLT, from Goldstein GMC. During my test drive I mentioned to the salesman that the truck feels like it hesitates and/or bogs down when you accelerate at slower speeds. I was told that this is how the vehicle is designed to shift, and that I would get used to it after a while. Well I haven't gotten used to it, nor do I appreciate the fact that I spent $50,000, on a truck that I am totally dissatisfied with. I returned the truck several times to the dealership, and complained about the same issue. And I have been told that this is normal for this vehicle. I will never buy another GMC product! And I will advise friends, and family members, and anyone else who will listen, that GMC products are unreliable and the company does not stand behind their product!!!

I bought a new 2016 GMC Sierra SLT last year, I wanted a nicer truck that was completely loaded and better color, after trading in my 2013 Sierra SLE Kodiak, which had no issues BTW. I've always been a GM guy. I have had numerous GM vehicles. The first day I took this truck home I found it shaking/vibrating bad. Was at the dealership countless times, and countless repairs. I don't know how many tires/rims had finally been replaced. But it still shakes. Called GM support and all they said is "the dealership had tried their best". And for me to deal with the problem. Wow, what great service. The truck only cost me $70+ and I bought the top extended warranty for peace of mind... Haha on me...

GMC SIERRA 3500 DURAMAX DIESEL LML. Ever since I bought this vehicle it had minor detail problems that came up more than it should. I always had each problem taken care of quickly. I've owned General Motor vehicles all my life which mostly were trucks. I had this truck breakdown near Buffalo and was towed to Mike Smith Chevrolet where the technician looked at it and said yes the motor is bad and didn't even hook it up to a scan tool. It blew my rear main seal out and was leaking oil. I was charged 200.00 there for five minutes of the man's time to guess exactly what happened and then didn't even offer to fix it but told me to tow it back to GA! That's an expensive tow bill. And then the company pressured me into buying a new Denali so I could haul my broken truck back to GA.

Our truck has been in the shop for more than 3 weeks now for warranty work. Apparently, the necessary repair part is nowhere to be found. I've contacted GMC twice via online chat, was informed that my particular issue required escalation and that I would be hearing from someone. I have not. The Service Rep at the dealership has been going above and beyond to get this resolved. But the logistics of this part seem to be out of the dealership's control. They provided a loaner, but we own and operate a campground and need to tow a 5-ton trailer before we open for the season... The loaner is a small truck that is more like a car. We've been considering buying other GMC products, but I won't now because of their inability to provide repair and replacement parts in a reasonable amount of time and their poor customer service.

Leasing a brand new 2017 GMC Sierra slt all terrain edition and 3 days after I drive it off the lot the thing's pissing transmission fluid everywhere. It gets towed from my job leaving me stranded at work and the dealership couldn't even accommodate me with a vehicle to get home from work. Then the tow truck company damages the front valance and the dealership tells me it's my problem. Now I have to deal with the tow company. This this is suppose to have a Bose sound system and the front speakers sound raspy and blown. This truck has 160 miles on it as I'm writing this and it's already a nightmare. Thank the good Lord I leased this toilet.

I purchased a brand new 51k truck in October. Since then the hood and rear door have been repainted due to paint flaws from the factory. Now there are scratches and swirls all over the truck just from drying it. The dealership has buffed the truck 3 times and said they can't buff it anymore before ruining the clear coat. So I filed a complaint with GM and the district manager came to look at the truck. He said it was my fault and I shouldn't use anything but air to dry the truck. And it's acceptable due to epa changes. That's funny my father has a brand new Ford with no problems and my buddy has a Dodge with no problems. The paint on this truck looks like it's 5 years old. Do not buy a new GM truck unless you don't care what it looks like.

In 2013 I bought a new Sierra Denali. It's is a $50,000+ vehicle. I decided to pay that price for a new vehicle, and buy the extended warranty, because I didn't want to have to worry about maintenance and minor repairs. I am currently at 65,000 miles. I still have 5000 miles remaining on the extended warranty. So far I have not had any mechanical problems; only cosmetic. I have had to replace a door handle and a windshield wiper cover. Now I have a crack in the dashboard right by the airbag compartment. I contacted two dealerships and was told that to repair or replace this is not covered under the extended warranty, and was advised to call GMC directly to see about assistance in paying for this.

2010 GMC Sierra 1500 SLE 5.3L - As I sit here today the dealership that has my truck is telling me the amount to fix my vehicle will be $5,600.00 due to a camshaft problem with only 63,263 miles. Bought this truck used with 39,864 miles on it to pull small camper with for short trips and have taken very good care of. While coming home from work I heard a noise that sounded like a fan clutch or belt issue, next thing I notice the check engine light came on and then started blinking along with messages that the traction control was disabled and the senatrack was also disabled and engine started missing and would not go. Had it towed to my local mechanic who does all my work. He call and said it was something in the motor and I needed to take it to the dealership because he does not do that kind of work. First I was told it sounded like a value spring but they was have to take the covers off to make sure. That was when they called back with this news.

Had this truck over 18 years and it still performs perfectly. I have had only normal maintenance--oil changes and two brake jobs. I have the Vortex engine and it has never given me any trouble. I have driven it cross country many times and I would trust it to go anywhere. Only bad thing is the body is rusting in several places but it doesn't affect the performance. I researched this vehicle before I bought especially the small V8 Vortex engine that just came out that year. This is the best investment I have ever made. I love my truck even if "its body" isn't as beautiful as it once was. My friends with the new fancy vehicles are always having to have repairs done on their cars. My truck is still getting 18 to 19 MPG just around here.

I bought a used GMC crew cab about three months ago. It had little under 25000 miles. Four weeks ago went on a hunting trip to Colorado from Mississippi pulling a trailer which didn't have but less than 1000 lbs on it. I was hesitant about the towing of the v6 but the dealer said it would do fine. Just outside of Albuquerque New Mexico the motor blew up. I was wishing I had followed my instinct then dealership where they towed it to done everything they could for us but it was like their hands were tied.

I have owned 3 GMC Denali vehicles and by far my 2008 Sierra has been the worst for quality. Right now I have dash that is disintegrating with cracks everywhere and the dealer wants a whopping $1400 to repair which is simply unjust. I paid close to $50k for this vehicle and expect better quality. So far the list of things that have broken are all 4 door locks, three door handles, fold out mirror, ac controller, ac door, cruise control switch, Bose amplifier, and of course now the $1400 dash which really chaps my hide. I want to stay a loyal GM buyer but GMC is making it very difficult when quality has been compromised to this degree. My previous GMC Denali’s were top notch with very few problems. At this point I will be forced to venture out and shop for different brands.

I bought a 2014 GMC Sierra SLT Z71 crew cab Jan. 2014, it's Oct 2016 now and the transmission is done. I spent over $80,000 on it and now I'm lucky to get $20,000 for it. There's only 176,000 kms on it. I thought these trucks were built to last, it's supposed to be a work truck and I used it as my personal vehicle!! I took very good care of it, always changed the oil when necessary. Did everything I was supposed to. I was told my transmission fluid needed to be changed so I did just that. Well now I don't have a vehicle and I'm out $60,000. Biggest mistake of my life was changing the transmission fluid. Reading some of these reviews also has me regretting buying this truck even more!! This truck was built on a Monday when everyone was hung over or a Friday when everyone's in a hurry to leave 'cause this is unheard of for GMC trucks or at least I thought. :(.

The chrome started peeling from my wheels about 12k miles and 9 months of ownership. I took it to Don Elliott Autoworld and addressed the situation with Theresa **, the service manager. Theresa immediately said that the "DM" would deny the warranty claim. I urged her to submit it anyway, so she did. I had to bug her for nearly two weeks to get the denial, which was total BS. I contacted GM directly and they just agreed with the "DM" and dealership and would not do anything but state that "environmental issues" caused the flaking/peeling.

Posted today, 03:28 PM. I purchased a completely loaded 2016 Sierra 4x4 Double Cab. Tax, title, extended warranty, everything out the door was pretty close to $60,000. Now when I test drove the truck I instantly noticed a vibration on the freeway. The salesman told me that it was just a simple flat spot in a tire from sitting in the lot. Sounded reasonable to me. He said, "Don't worry. It would be 100% fixed!" Well my truck that I've only owned for six weeks has now been back and forth four times, and the last time being for 10 days, and the dealer has now put three sets of brand new tires on the truck, and tested other miscellaneous things, and it still has the same vibration, and they are now telling me they don't know what the problem is that I'm going to have to deal with it! So as of right now I am searching Lemon Law lawyers! So if I was you I would stay as far away from any GM product that you can!!!

Thank god I leased and not bought a new 2016 GMC Sierra SLE. At 362 miles the engine blew up and the #7 piston was trashed. Dealer blamed it on the FMS. Truck has had constant hesitation along with hard shifting and loss of power from time to time. Now with exactly 5100 miles on it the same issue happened again. Engine light flashing, clunking noise under the hood, engine kept shutting down and now engine is once again torn down. 1st time the dealer had my truck just shy of 1 month. Hit over a month and the lemon law in Indiana kicks in. 3 days now on round two and no news. I'll be going back to Ford next time. Lesson learned.

I noticed a couple weeks ago that the dash on my 2011 GMC Sierra was cracking in three different places. I called a couple dealerships and they told me it was happening a lot. So I told them I only have 41000 miles on the truck would they be able to replace it under warranty since it is a flaw. I was told they are doing it only for the people that purchased the truck no one else. I ask them to explain that to me and they said that came from their head office. If you know you have a problem the smart thing would be to fix it so people don't go sour and tell everyone you don't care about their problem. I'm sure I'm not the only one, but I will tell you this I will not purchase a truck from someone that knows they have a problem and don't fix it. Now I know why everyone says buy a Ford. What a shame. I do not recommend anyone purchase a GMC ever.

Bought my 2010 GMC Sierra. The windshield wipers started acting up, just move a little and stop. I replaced motor and switch but that did not fix. I found out it is the wiper transmission (linkage). I took that off and it was rusted and froze up so will not move wiper arms. I ordered one from Dorman and after 2 days they call to say they are out of stock, so when I call all the part houses no one has any of these parts. First of all this should not happen on a 2010, second of all they need to have a recall on these because from what I have read my GMC is not the only one this same part has messed up on.

To sum up what happens when you buy a brand new vehicle from a GMC dealership. I bought a "brand new" 2016 Sierra 1500 All Terrain in black with only six miles on it. Photos will show just what you get from GMC or an affiliated dealer. Where did the damage to the paint come from, who knows? Both GMC corporate and the dealership where said vehicle was purchased both deny they did the damage. I guess it's normal for brand new black vehicles to look like this. Mind you the photos don't even show all damage... more like only 10 percent of the swirls that are really there. Uploaded is one picture of the vehicle purchased and four more photos of the swirls that cover every square inch of my truck minus the tailgate.

I was robbed when I bought 2015 GMC S. I have inherited a lemon with no fixed insight, I am too stressed to deal with runaround with the dealership. I got a $50,000 vibrating vomit truck. One of my child is 4 years old and can't long rides in my truck because he gets vibration sickness. This really problem I think GM is getting away with and should be on Nightline 60 Minutes. I wish the lawmakers would buy this truck and maybe they could write some laws protecting the consumer. I know one thing for sure. GM is writing their own death certificate. The amount of people this affects are mad just like me.

My new 2015 Sierra SLT has had hesitation issues since the day I bought it. I was told over the phone the computer needed to learn my driving habits. Then I was told in another phone call that this was the normal operation of active fuel management. The dealer never went for a test drive or even looked at the truck. I finally went to another dealer when it got to the point where it felt unsafe. I often pull off the road or interstate to avoid being hit in traffic. I never know if the truck will go forward or hesitate or how long the series of hesitations will last. It feels like the transmission is confused.

Bought a 2015 Sierra. Almost immediately after purchase exhaust started making sounds on acceleration. Multiple times in shop and 3 exhausts later it may finally be fixed. I have hardly had my truck on bumpy roads. Dash rattles... driver's side window is loose, that's being fixed this week. My z71 suspension is very rough. Bumps feel like the box of my truck is going to come right off. Recently my steering column started making rubbing sounds. I'm so thankful I spent $60 000 on a truck that's unreliable and proving to be more of a hindrance than pleasurable. GMC will not buy my truck back. I'm left with the option to trade in and lose $20000 or keep the piece of crap. The dealership returns my vehicle with the gas tank on empty and not once have I been offered a courtesy car. This has been by far the worst purchase I have ever made.

I am a 2004 GMC 1500 truck owner. My truck has anti-lock brakes. I am fully aware of the recent disallowance of recall for 2004 GM truck era rusty brake line issues. The anti-lock modulator effectively negates dual action breaking because of its less expensive design. The brakes effectively become a single action braking system and ANY broken brake line results in a complete loss of ALL braking ability. This is a violation of consumer safety protection law. I know that this loss of ALL braking ability happens because it happened to me!

I buy 2011 GMC truck 1500 about 2 years ago. The anti lock comes on. I change fuse 4 times!!! And my radio went out too at same time anti lock!! So now at dealership they call me say my truck don't start really!!! I told them it might be bad wiring inside. That is common sense!!! I might get my truck back when it is paid off.

I purchased a new 2013 GMC Sierra 4x4 new from a Bedford Hts, OH GMC dealership. At just under $50,000. I have the Vortec, 6 liter and the truck is a 4 door with a long bed. I run a construction company and needed a reliable truck. Thinking GM has made some significant strides forward and being fond of GM, I bought this truck. I was a little disappointed with the fuel economy of 11.2 miles per gallon. At 36,500 miles the windshield wiper arm assembly froze up. I replaced that myself after discovering there was no warranty. I replaced oil and filter with synthetic on the recommended basis in accordance with the computer display. I also do almost all of my own maintenance as it is required.

The paint on my 2015 gmc 2500hd started to show rust spots all over the vehicle about 6 months after buying it and the dealership claimed that it was environmental so I called GMC custom care. Well months later I'm being told to either just deal with the paint issues or trade it in. This is the worst customer service I've ever dealt with.

My 2014 Sierra Texas edition A/C went out after 1st summer with 45,000 ml. I'm told I'm looking at a 500.00 repair, can't see 50' in front of you with headlights, H D is in and out on radio enough to drive you crazy. I'm very dissatisfied after reading all the problems with this year model, record breaking problems in 2014. I'll never recover from this purchase of $41,000.

I purchased a certified used 2014 GMC Sierra All Terrain 4x4 with 17,000 miles on it. It has been an absolute nightmare. I have taken it to the dealer numerous times for vibration issues, rust issues, transmission issues, broken seat (and I'm not that big), leaking radiator, engine noise, shock issues, electrical issues...and probably more that I have forgotten.

Bought this truck new in 2008. Drive less than 5K miles/yr so it currently has only 38K miles on it despite being 8 years old. Way out of warranty so I don't bother going to the dealer with issues. Only I drive this truck and am very easy on it. Last week started making horrible noises from front drivers wheel. Thought it was CV half shaft assembly and bought the part. When I jacked up the truck to start changing the half shaft I discovered the wheel bearing completely shot. What kind of junk is GM using to build these expensive trucks when a major part (a safety part) fails at 38K miles?

In December 2015 we purchased a new 2015 GMC Sierra SLT 4x4. In a matter of weeks, we started smelling a terrible odor like a dead animal. When we took it to the dealership, they said it was leaves and cleaned the leaves and filter. However, that did not resolve the odor. We took it back and was told that there was a water leak around the brake light over the cab. They replaced the carpet and insulation and sprayed. It was a very strong deodorizer. The dead animal smell was removed but there was still a very strong odor.

We bought this truck used in December of 2015. We have put 15000 km on it. The exterior mirrors fold in for no reason (4 times). The forward crash avoidance light has come on for no reason 3 times. The heated and cooled seats do not work on the command start. The dash display has 2 circles instead of one. Service alert comes up on display numerous times. I have discussed with local GM dealer and they have twice looked at it and tell me there is nothing wrong as they can't replicate it and there are no code error present.

I am 60 years old this week. My 2015 GMC SLT Z60 is my 50th personally owned vehicle - of the 50 vehicles, 27 were GM's. Summary first - I have hired a lemon law attorney and I will NOT be fooled by dealer BS such as "that is normal, acceptable, and inherent with all trucks like yours". PLEASE - save it for the cerebrally challenged - won't work with me, or my LEMON LAW attorney.

2013 Sierra Denali 40,000 mi. Contacted Customer service concerning Dash cracks & was told my part would be $250.00 for replacement. My question to G.M. is why are some done for free & others charged $1,200.00 or more? These are clearly cheap pieces that were falling apart long prior to 2013. I was also told G.M. does not offer "Special Consideration" to owners whose vehicle are out of warranty & the $250.00 was the "Best" they could offer. "REALLY" G.M. it is time to step up & treat your customers as if they had "Bailed" you out in the past. I have always had a G.M. in my garage but no more.

We have a 2008 Denali Truck with 110,000 miles on it and the value spring on the No.1 piston went out of it and when we took it to the mechanics, there were two other GMC trucks being fixed for the same thing; and we have friends who have relatives with GMC trucks that have had the same problem. Should there be a factory recall and how many complaints are there with the same problem.

I have been greatly impressed with the comfort and reliability of my 2011 GMC SIERRA. I purchased my 2011 GMC Sierra 1500 crew cab in November of 2012 with just over 20k miles on it. Since it was a certified used vehicle I received about 3 free oil changes as part of the package. Also the dealer gave me a free oil change for buying it. Altogether I didn't pay for an oil change for the first 2.5 yrs I owned the vehicle. Since I have had no repairs and free oil changes I literally drove the vehicle with no cost of maintenance for the first 2.5 yrs I owned it, and it was used!! Talk about impressive. I currently have just over 50k miles and still have the factory tires. They are close to needing replacement due to tread depth but have only had 2 low tires, which I was alerted to prior to further damage with the tire monitoring system, and they were both from nails I picked up somewhere.

We bought a new GMC Sierra from Bob King Auto in Wilmington NC. The headlamps are defective and very dangerous. You can't see well at night or when it's raining. I had an appointment with Bob King to have this issue with the headlamps repaired. All because of the bad review I gave GM, they are refusing to work on my truck which is under warranty and has a little over 5000 miles on it. So I'm being punished by them for being honest. General Motors has been aware of these headlamps on these trucks since 2014 yet they refuse to correct this. Not only is these headlamps putting me at risk, they are also putting others at risk. Also, I did take my truck to another dealership to fix this problem but they couldn't fix the problem. They tried. In my opinion, the only way to fix the headlamps are to replace them.

I have a 2001 GMC Sierra 1500 SLE. I love this truck! I bought it at 187,000 miles and it now has over 206,000 miles. Only issue when I bought it in Feb 2015 was the EGR Valve and the battery needed to be replaced. I have replaced the tires and there are minor issues with the truck that I haven't fixed. These issues is that the fuel sensor went back and the AC Regulator went bad. I think I could drive this truck for at least another 100,000 miles. Prior to this truck, I owned a 94 Silverado with 305,000 miles and was still running! Treat the vehicle right and it will treat you right!

I have a 2011 gmc sierra that engine burns oil more than gas. Service stabilitrak comes on randomly. Fries 4th cylinder spark plug every 30.000 thousand miles and they think it will be fixed by replacing a valve cover. Last gm for me.

I bought a new 2015 GMC Sierra 2500 in September. My son bought new 2015 GMC Sierra in October. We noticed his truck had rear wheel liners and mine did not. I called the dealer I bought my truck from and they said some trucks came without. But they can order them for $120 each. I called my friend that owns a body shop and ask him to get a price. He called and said he can get them from the dealer for $60. What the hell did the dealership I bought my truck from, think I was an idiot? Now, my question is, am I supposed to have these on my truck as normal equipment? Did GMC forget to put them on my truck?

This is a truck that we walked in and paid cash for and that was where the friendship with the dealership ended. We started having issues about four months after we bought it with interior issues. Then the engine and transmission issues started. Codes, tows, recalls and bad service. The dash cracked after two years and we were told it was no longer covered.

Transition hesitates, seems to struggle pulling an RV. Brought in 3 times, was told computer reads all good. Nothing they can do!!! 85000.00, 2015 and they need to wait!! For what, a recall? An accident! Ugh.

I have an '03 GMC Sierra 1500, and I'm pretty sure it's made out of recycled Datsuns. Everything is rusting on it. Everything. Brake lines failed 5 years ago, the rocker panels are non existent, the fenders will be missing after this winter. I had a spring shackle break off of the frame while driving on the highway 3 months ago... And the sad thing is, I've taken great care of this truck. It's embarrassing to drive. Even the chrome bumpers have rusted through. Then there's the wind noise. I had a passenger ask me if a door was still open last week.

Purchased new 2015 Sierra. I still have the temporary tags on, 500 miles so far. Called the dealer, spoke to service department. I'm experiencing a hard shifting from 2nd to 3rd gear in auto, with clunking noise. Rep on phone told me this is normal. I'm reading others are having this same problem. It’s a brand new $40000+ MSRP vehicle. Extremely disappointed with GMC.

Definitely noticeably worse with the AC on, took back to dealer. Said GM is aware of the problem but no fix yet, are you kidding me!! Anyone else having this issue??

I bought a 2014 GMC Sierra in January. I have had numerous problems to include hesitation upon acceleration, current switching of gears at low speeds which in turn cause a large clunking noise. The steering sticks when turning to the right. The transmission makes a humming noise which is supposed to be repaired today. This is the third time I have had it in for this issue. My center console of the truck vibrates so bad that my coffee comes out of the lid. I have a clunking in the rear end which I was told is normal. Why would anyone want a truck the clunking is normal. I keep getting the runaround and getting nowhere. I am considering contacting GMC corporate. Anyone have the same problems. I should have bought a Ram 1500.

I have owned several GMC vehicles including one 2008 Sierra with 300,00 miles. I still drive it everyday. Great truck and keep it serviced regularly. It is very dependable. Also have an 2014 that my wife drives. Great truck, no issues. I keep all my vehicles and equipment serviced with good tires. No complaints!! Will continue to buy GM products.

Okay in my GMC Sierra there are some speakers that only work when it is really hot outside. We have searched the web multiple times and can't find out how to fix it. Can anyone help me? One speaker works all the time but the rest don't.

I had 3 GMC Sierras in the last 4 years. I had nothing but steering and idle problems with all 3. They are junk trucks. I'd take a Silverado over GMC junk any day. I had a 95 Silverado. Rarely any problems. I demand some kind of reimbursement.

I have a 2004 GMC Sierra, 3500, diesel, dual wheel. 112,000 miles. Replaced both front and rear bumpers that rust from the inside out, replaced both left and right side cab corners and rocker panels again that rust from the inside out. Fabricated new right rear top shock mount because original rotted out. Replaced left front A-arm (rusted through), replaced all fuel and brake lines, front wheel and hub assemblies (3-4) and now the frame is so rusted that it will not pass Maine state inspection.

My truck, a 2015 Sierra Denali, has transmission problems, crooked steering wheel, and the driving experience in general is horrible. Please, if anyone wants to start a collative suit against GMS to get the money back, contact me at ** Jorge. I have not check with an attorney yet but I can stay with this piece of garbage for 5 years and $70,000.00 to pay. Please contact me to see if we can join forces to be heard at GMC. Thank you.

2014 Sierra 1500 - Bed liner has rubber disks that should fit in the holes where the tie down hooks are not in use. Problem they don't fit. 5000 mile check in ask dealer to place them in. Dealer said they don't fit. Now, the problem is debris is getting under liner. I want a new liner.

I bought this truck brand new and I love everything about it until I start driving it. From day one I've had issues with the truck hesitating during acceleration and the truck not shifting smoothly. This is most noticeable in stop and go traffic and when transitioning from braking to acceleration. I've almost had three rear end collisions due to the hesitation and the vehicle lurching forward when it finally decides to go. I took the vehicle back to the dealership approx. 2 weeks after my purchase with the complaint. I was told the truck was still in the break-in process. So, I drove it until I had 5000 miles on it and returned it to the same dealer with the same complaint.

Purchased 2010 Sierra Denali - Has defective and dangerous rims. Contacted dealership within 2 weeks of buying this vehicle off their lot. They inspected and told me they would not do anything because the truck is 5 years old. I have other issues that I am waiting to see what they are going to do with, but they told me flat out the rims are my problem. $34,147.22 spent and since they have their money, I am now on my own! Was told that this is not a "Certified" used vehicle, so it is like "As is". The enclosed pictures show the problem!

We have a 2006 GMC Sierra and it is giving us nothing but problems! In December 2014 the brake lines blew, then from there has been nothing but more problems. The exact same problems that everyone else is having. I just read each complaint and can say we have at least one issue from each complaint. My husband has never been a Ford fan, now he is looking into a Ford!

I purchased my 2014 GMC Sierra in Dec 2014. The transmission has made a clunking from day one, and has been getting worse by the days. I took it in at 7,200 miles. The service said that the clunking from shifting from second to third was normal. They even gave me a memo from GM stating that this is normal. The truck is in the shop today. Now it clunks when it down shifts from any gear, and if you give it gas, it will rev up to 4,000 rpm and the motor will stay at 4,000 rpm, and the governor just holds it, and the truck acts like it is in neural. The only way to stop it is to hit the brake and the service dept. Just called and said that is normal.

Two $300 door handles have now broken on my 3-year old $50,000 truck. Low miles, and these handles are made to break. They do not have the design strength of a kid's toy. This is a rip off by GM and I have 4 door handles on my crew cab. This is a safety item too, as the part will snap in a collision, causing the door to with open---or NOT open!

We purchased 2014 Sierra on December 13, 2013. 40,000 dollars plus ttl. First week windshield wipers went out... Noticed antifreeze smell and was told it was just new. Six month later (June 2014) had radiator replaced. By January this year I noticed antifreeze smell again and finally was able to get it to the shop and guess what radiator is leaking in the same spot. The dealership sells a ton of GM trucks and they were honest about the radiator problems they have had and that all the ones with problems leak in the same spot.

The roof on my 2008 gmc 2500 truck is checking and paint peeling off. The hood is starting to do the same thing. The rear wheel wells are starting to rust where the paint chipped off. Truck has been well taken care of and has 130,000 miles. Now it needs a whole paint job. GMC rep said he could give me a 1000 dollars off a new one. You can't stand behind this one, why buy another. 6 years and it needs paint, something wrong. Truck new went for 55k. Last one I'm buying. Going to Toyota.

I purchased my GMC Sierra new with 13 miles on it. I had issues from the first week with the vehicle hesitating during acceleration and the transmission not shifting smoothly in stop and go traffic. I returned it to the dealer within the first few weeks of ownership and explained the issues. They told me the issues were part of the break-in process. After 3000 miles, I returned the vehicle to the dealer with the same complaints, figuring the break-in process was complete. This time, I was told this is the way all 2015 GMC trucks with the same engine and transmission package drive. I'm not really happy with its performance and feel it's most likely a computer program issue that could easily be fixed. Has anyone else experienced similar issues? I look forward to getting some feedback regarding this. Thank you.

2015 GMC Sierra 3500 rust on all the underbody components - Purchased pickup new on December 31st, 2014. Vehicle now has 10,890 miles on it. Everything underneath pickup, that is not aluminum, is covered in an extensive amount of rust. I took it to Red Wing Chevrolet today for a solution, and they told me that this is now "normal and acceptable" by GMC.

Purchased 2008 GMC Sierra new; never used for towing at anytime during ownership. Ring leaking oil into cylinder and shop recommends new engine. Engine has 130,000 miles and all service performed by GMC dealer. New engine replacement cost suggested at $5800. Contacted GMC representative and told high mileage; so no assistance provided by manufacturer for repairs. Didn't think in this day and age that 130,000 was considered high mileage? GMC recommends tune-up at 100,000. Go figure?

2014 truck vibrating about a month ago. Rear end making clunking noise. Warranty change part in rear end but roaring noise and vibration continue. Dealership says tires chop up with 37 thousand miles and they expect me to buy tires but want guarantee that will fix vibrations. Want me to pay for elimination process.

I bought a brand new 2014 GMC Sierra SLE on 10/29/2014. The vehicle started to have a vibration issue immediately after purchase. The truck has been back to three different GM service dealerships in two different states, 14 different times and GM cannot figure out what is wrong with it. My new buying experience has been a complete disaster and an enormous waste of time and energy.

I have a 2007 gmc I bought brand new. It's been extremely well taken care of. Has just over 100,000 miles. The dash is cracking terribly. As a result of the vibration of cracking dash my stereo failed & the cracks around the airbag are getting worse. I don't drive it much now because I'm afraid the airbag may deploy. I contacted gm & they basically say oh well. Sounds like I need to buy a new truck. Really!!!? The dash falls out before it needs brakes? GM was very disrespectful & showed no concern at all! I don't want a new truck. I just want my $30,000 truck fixed. Any help would be appreciated. Thanks.

Well it's still under the 3-year-36000 miles and I am getting the runaround about the wheel pitting. I thought bumper to bumper meant it's all covered but I guess once they have your money well that's not covered. So Tasca GMC sucks just as bad as the rest. I had GM all my life. Now made in the USA means it's a piece of **. It's a 2013 Sierra.

2014 GMC Sierra slt - Bought a new GMC truck in March 2014. Paid $50000 for had a vibration in it. Took it back to dealer, force balanced the tires-- same vibration. Check it again, they told me it was a normal then got a roar in the rear end. Try to get a new rear end. No luck so they change the gear and the bearing. No more roar but still vibrating. Took it to another dealer, change the drive shaft, fix the vibration that is not normal for a new truck. This past winter I did not use it much. This spring 9000 km on the truck, vibrating again. Install 4 new Michelin tires. Still vibrating. Service told me don't know what the problem is. I am trying to get a buy back on the truck.

I have owned over 100 vehicles in the past forty years and found GMC last decent year was 1993. Since then the frames, abs brakes and transmissions have all failed to withstand weather and normal wear and tear. Best cars I owned was 1964 Dodge Dart 50th anniversary and my 1969 Firebird 400 still all original with no mechanical problems. GMC needs to step back and bring back reliability when transmission's outlived engines.

Purchased 2014 GMC Sierra Denali in May 2014. Purchased vehicle in Texas and I live in New Mexico. Got back home and thoroughly examined the vehicle the next day only to realize the entire vehicle had been repainted and some new parts were on it. The front bumper sections do not line up from one side to the other, there is severe overspray in all door jambs, flat and glossy areas under hood (all GM vehicles have a underhood finish that is all flat), there was buffer burnthrough on the fender, well I could go on and on about the problems. The vehicle now has 7800 miles and the transmission is slipping and the front end has a terrible 'squeak' when I go over a bump. The dealership was of no help at all. The Sales Manager's remark was-'GM made the vehicle, let them fix it'. In other words, my hands were tied with the dealership.

Bought a new 2014 GMCHD Diesel Denali. It broke down 4 months ago and still have don't have a replacement. ** at GM Finance who is some attorney has been holding up the paperwork. Wish someone with some kind of authority would look into this.

2014 GMC Sierra almost $50,000 truck. Have not had it for a year and washed it today and found rust spots all over the white paint. Not happy at all. I found a forum with people complaining of same issue. Filed complaint with dealership today and am waiting to see what they say. Have never had another vehicle in my 20 yrs of buying vehicles to do this.

Just BEWARE OF GMC, in totality. I have had three dealerships work on my vehicle, UNSUCCESSFULLY. I bought a new 2013 GMC Sierra, 4x4. It has had transmission problems since the first week I purchased it. The first dealership in California, Temecula Buick GMC told me not to worry because I have this great warranty that will cover me. After three visits to service in California, and a trip across country, I took the GMC LEMON to Alexander Chevrolet. They fixed a few items, but the truck still down shifts with a clunk. Three more trips to the service department at a third dealership, back in California, Paradise GMC still said they could not fix the vehicle.

I inherited this truck (gmc sierra 1500) from my grandfather. He kept track of everything he fixed on this pile of crap. From replacing head lights to transmission problems. You’d be hard pressed to find someone who takes better care of their vehicles.

I love everything about this truck except that my dogs if left in truck while I run my mail across street to mail boxes can lock me out of truck and them inside because of where the lock button is located in the side door arm rest and where window controls also are located. This happened one time so far but once was enough for me.

I decided I wanted a truck back in 2009, and was on the market for a mid-sized or full sized truck. I have had nothing but issues with Ford, GM, and Mopar, so I was looking for a Tacoma. But, there was a 2009 Leftover on a GM lot that I went to look at. It was the right price, and had the 4.8 ltr V8. Which I figured would be compatible to the V6 in the Tacoma. I have owned GM products in the past, a 79 Monte Carlo, which might go down as the best car I had ever bought, to a 00 Cadillac which might be the worst car I have ever owned. But I figured, it is an old design, RWD, Frame, v8 and automatic. How hard could that be to screw up. Lesson learned… The truck started immediately showing why GM went bankrupt.

2003 GMC 2500hd sierra duramax - I purchased this truck with 99,000 miles on the odometer and it has 119,000 on it now. Last july I put brakes on, and while bleeding the air out the right front line ruptured. I repaired it, then the left front ruptured before I could drive it. So I fixed it and drove it and all seemed to be ok. So I put it in the garage because I hardly ever drive it unless I need to haul something, I drive my car. So I the next time I needed the truck I pulled it out and pushed on brake pedal. It didn't seem solid so I discovered another ruptured brake line going to the rear axle. Now I have the bed off and I have ordered a $300.00 stainless steel set of new pre-bent lines.

We have a 2009 GMC Sierra Denali. We noticed a crack in the dash that runs from the driver's side all the way into the passenger airbag. We took it to our dealership since we have a bumper-to-bumper warranty. We were told it is not covered under warranty even though it looks like it poses a safety issue. They called GMC to see if they would make an exception and was told no.They wanted to charge us $1000 to replace. The crack gets worse and worse. Why won't GMC take care of this obvious problem?

2000 gmc 2500 reg cab lox 4x4 - 286,000 very hard use miles, 2 water pumps, alt, fuel pump, besides the usual brakes front end suspension pcs., couple u-joints. This is the best truck ever. Just keep it maintained and it will do whatever I need to. The 6.0-liter with the auto 4 is damn near unstoppable except with the Firestone steel text tires it came with. Got rid of those immediately. Bought it February of 2000 with 10 miles on the odometer and 286,900 now. I've always wondered why this truck came with the auto 4 option being a 2500. I have an 2001 2500 HD Chevrolet also, and it doesn't have that option and the whole 4-wheel drive system really sucks. Both trucks have posi differentials also. Not much different in another way. Can't believe the newer Sierras are having such problems because I would definitely buy another if this one does one day decide to hang it up.

My letters & phone conversions with gmc have had little effect to the problems on this truck. Sent to gmc - 2013-01-08 -vin # ** .The starter broke off the engine mounts and the flywheel had teeth broken from it. Each were replace in grand junction by bear alignment. Now the engine trouble light is lit which according to the trouble code P0 700 -- is a transmission control problem. Following many occurrences of the engine trouble light, I purchased a edge performance module to determine the codes on this truck. This truck has had more than its share of problems. But at the cost of repairs vs the price of a new truck, I am trying to get the thing repaired as they happen. At 80 years of age, and having to live under the present government in power, I have no choice but to keep this problem truck operating.

Nothing but problems with this truck from DAY 1. It started with a shake, which turned into 4 new tires, which turned into the drive train, which ended with the axle, new shocks, and the list goes on and on.....

2004 GMC Sierra 2500 - I was coming to a stop sign and the brakes went all the way to the floor. No warning ever - just gone, no brakes. Luckily, no traffic was coming because I could not stop and this time I wasn't pulling my camper with my family inside. All the brake lines are completely rusted as is everything else on this truck. Bumper rusted, rocker panels are gone, rusting under gas cap. Most of the lights on the dashboard already don't work as the RPM gauge isn't working either. I've never seen a truck fall apart like this with less than 140k miles. I've already put so much money in this truck, what a shame. Never would I buy a GMC again. Obviously, this is a major issue with all these trucks and GMC isn't showing any compassion or responsibility for what is an obvious issue from seeing how many complaints they have in regards to this.

We have had our Sierra for less than 4 years now and it is no longer under warranty. So my drivers side exterior door handle is broke and I have to fix it out of pocket now. I have had 3 handles break and this is the second time that this one has broken but the dealership that replaced the original won't replace this one, since it is just shy of being out of warranty. The scary part is, if I get into a wreck and they have to remove me from my vehicle, they will have to find another way because it's barely hanging on. I will be getting it repaired, but at almost $300 a handle, this has become more than cumbersome and too expensive. I will NEVER purchase another GMC product... Or GM product for that matter.

I was ten acres into my woods when I got a flat tire. I tried for three hours to get the spare tire to crank down, but it was rusted in place. I tried breaking the large wing nut and spring using a three pound hammer, I tried cutting the cable with a hand held pruning shears and I finally attached one end of a heavy chain above the tire and the other end to a tree and drove forward until the cable attachment was ripped out. I see I'm not the only one with this complaint. Hand crank windows are very difficult. Gear indicators are black on black.

A GM dealer replaced the fuel level sensor in my truck, which was working fine before they touched it, and it has not worked right since. I complained to the dealership and they ignored me for two years. Finally I emailed customer service (cac@gmc.com) and Riza told me GM would pay to have the fuel level sensor fixed. I made an appointment to have it done, and now GM calls back and says they will not pay for it. They wasted my time for nothing. Bad part, bad service from the dealer, and now lies from customer service.

2008 GMC Sierra - At 36,600 miles, window and door switches stopped working. Found out others had the same issue. GM was not willing to repair. Two valve rollers went flat at 56,000 miles, was under warranty, thanks goodness. Now at 119000, heavy blue smoke and burning through a quart of oil every 1,000 miles or less! Dealer looking at it. I did some internet searches, others with the same issue, GM not offer a fix or recall. I was hoping that this truck would last a long time... apparently not.

The IP cluster scrolls thru the languages. It returns to English and works correctly at times. 2004 Sierra with 9000 miles. On going problem.

My truck (2011 gmc 1500) got new tires and an alignment, I hoped that would the hard steering, it did not. I would like to know how to make it correct. My dad has an older Chevrolet pickup and it steers fantastic. I ask the dealer and they said it is the euro steering, and I think it sucks. How can I change it or change something to make it steer better?

I bought my truck brand new Feb 2005. So far I have $10,000.00+ into it just for repairs. Transmission and another motor, front end, brake lines, both door handles on the back doors broke. Check Engine light comes on nonstop. Fix that problem and it's on again for another. Now service airbag light is on. 4 wheel drive works when it wants. Now because of all the repairs I have had to make, I have bad credit. It was either pay to have a tranny and motor put in or make a payment. So of course I paid for repairs and was late making payments so, now I'm stuck with this so called GMC SIERRA CREW CAB. Can't afford another vehicle. I've called GMC, they could care less. BUYER BEWARE!!!

2014 GMC Sierra, window sticker $49,500. In 40 years of truck ownership, this is the worst truck ever. The paint is thin and chips off if a hard shell bug hits it. The tires are Goodyear and made for this truck, no traction in rain or light snow. The headlights are so dim I'm afraid to drive at night. The radio does not hold a station even though I'm 20 minutes from 2 major markets. I paid nearly $1000 for the HD Bose system and all I get is really good sounding static. The GPS has a mind of its own. If you go past a road that is closed, it will spend the next 20 minutes telling you to turn around instead of plotting new route.

Was in a one-truck accident while pulling 1000 pound single roll of hay. Forced off the road. Had to have my truck towed in, No brakes, and rear drums cracked. Also Total electrical problems from engine light going off & on. So called repaired twice. Engine failed to shut off when key was removed. Had to unhook cables. Seat heaters come off and on in midsummer at will. Windows just go down while driving. No lights in dashboard. Off and on 3 visits to dealer. 5 visits prior to various our Truck repair shops. Each visit $500-$1687.00. Where can I get the truth on the honest repairs?

I have a 2001 GMC 2500HD diesel pickup. I bought the truck used and the previous owner, who bought the truck new, was meticulous in keeping up with the proper service. And, I might add, I have done the same. The truck had probably 80,000 miles on it and I now have approximately 186,000 on it. May 29, 2014, my wife and I were preparing to pull our travel trailer to Ohio to visit our daughter and grandchildren. I still had two thousand miles to go before the next service was due. I started to wait until we got back but, fortunately, I decided to do an early service.

I bought a used 2007 GMC Sierra pickup truck. The vehicle looked immaculate inside and out and had approximately 37,000 miles on it at the time. Just 3 months ago, I suddenly noticed blisters in the paint on the rear fender wells on both sides of the truck. I also noticed the same happening along the top rail on one side also on the truck bed. At about this same time, I had to take the truck to a vehicle repair location due to not being able to get my trailer towing electrical connector to work properly. I was going to replace the in bumper connector myself and had bought the part. To remove and re-install the part, I was going to have to lower and move my spare tire out of the way. It would not budge.

Most of what was in complaint above has happened to us, we have had to our truck...Had to replace the back axle gears twice now, both front bearing caps failed this year. The door handles are JUNK, had to replace them at least 2x's each because of the plastic..Brake lines burst for no reason. The front right light that is supposed to stay on burns out constantly so I don't bother with it anymore. The 4wheel drive buttons don't work anymore, got solution for that (make holes in buttons and hit manually with small screwdriver).

I drove this 2006 sierra off the lot with 18 miles on it. I had rust on brake lines and under hood after first year and at 40,000 miles I had to wheel bearings go out. I brought the rust concerns to my dealer as soon as I notice them and they blame it on everything else but their ** ups. My brake line finally burst and brake fluid sprayed all over customer's drive and under my hood. Had to drive home without brakes. While I was having brake line fixed I found out GM does not even have my brake lines in stock anymore for 2006 Sierra so I had to have this brake line custom made which costs more money and the line does not fit right so I have to use tape to keep it from moving around!!! I notice the real axle brake line had no rust on it at all, explain that GMC! Now I have 103,000 mile and my bearing are bad again and waiting on other rusting brake lines to burst!!!! I will never buy a GMC product again. They are nothing but BIG ** SNOBS. I will buy a Ford 2015!!!

I have been a loyal GM customer for 45 years and although GM has had its issues, they have been much less frequent or severe than the other two manufacturers. I have tried them all and still stand behind GM for their products, service and customer relations. "Thank you, GM."

2010 Chevy Sierra 4X4 - The HVAC will default to OUTSIDE air on most settings and this is unacceptable. It may be what someone at the GM design group thinks should happen but then, they do have severe allergies to tree pollen. I am force to freeze or roast because I cannot use the heater or the AC (and continue to breathe). Not a lot of fun when you dry by a skunk kill - which happens a lot too. My next vehicle will not have the "Feature"!

After reading numerous GM complaints and spending over 2 weeks with GM customer care case number ** and filing a complaint with NHTSA ODI # **, I have given up! I own a 2005 GMC Sierra and I am the only owner! So called Mr. ** is the only person to work on my vehicle. The truck has 43500 miles when without warning of any ABS light or prior brake issue, I was driving to pick up my kids traveling 45 mph when the brakes went out, I had to apply the ebrake and luckily came to a stop and returned home without incident.

I have 2000 gmc sierra 4x4. I have been trying to get new one for 3 years now and can't get them, only no after market one. The check engine light stay on, they say my fuel tank is warped. Its plastic 36 gal. GM can't tell me when they will be making due manufacturing is down. What can I do? I have emission, I have to do. Am I the only one with this problem? It is a 1000.00 gas tank.

I currently own a 2005 Sierra crew cab Z71 4wd pickup, which I bought new. I have had nothing but problems ever since. ABS system failed almost resulting in an accident when the pedal went to the floor. (solution- remove the 40 amp fuse and have regular brakes that you can control by feathering and pumping the pedal.) Airbag light is on. Instrument cluster is non functional- no tach, speedometer, fuel gauge, oil pressure, voltage meter, temp gauge. (solution- check levels etc. often and use gps to monitor speed) Oxygen sensors bad. (solution- ignore. I actually gained 3-mpg in economy by not repairing. If I'm getting that increase it tells me I getting more efficiency thereby less pollution without the sensor working.) Front right running light out. I replace it numerous times and it keeps blowing. Look at any oncoming GM vehicle with similar vintage and 9 out of 10 times one of the running lights are out.

Own 2009 Yukon, 2010 Sierra 4x4, 2012 Sierra 4x4. Bought all from Athens, AL dealership. All have had recalls for various sensors mostly one that cause truck to idle down and fail to run. 2012 truck went in first time with less than 5000 miles and has had 5 more since to correct issue. Very dangerous for my 19 year old driver and not reliable to start often when sensor goes bad. 2010 had same sensor issue and now one that caused oil pump issue and warned to stop engine immediately. Had to have it towed to dealer another 75 bucks! Truck has 65000 miles on it.

2013 GMC SLT 3500 HD CC DRW 6.0L Gas 3:73 Limited Slip. Purchased used from Chevy dealership in Red Springs, NC 12/17/13 with 17,638 miles on it. I was led to believe this truck was 100% faultless. I reckon I proved it is never too late to not believe a GM dealership. I am a mid-60s fellow who would like to think there is honesty someplace in this world, especially in the USA, but, alas, not at a Chevy dealership in Red Springs, North Carolina for sure. I had a long drive (1,250 miles) to get back home, and I was in a rush to leave a place that did not feel comfortable. I know why now.

In 2001 I had a 2001 Yukon XL that had cold air coming in from under the dash under the glove box. It was in the dealer 5 times for this issue. I asked, "How many more times will I have to bring it in before they consider it a LEMON and give me a new truck". The was then resolved. Now I own a 2013 Sierra (one step down from the Denali), with the same problem. I've had it into the dealer 3 times and still not fixed. They resealed the HVAC box twice and stuffed a bunch of foam under the dash. Not the fix. They told me this normal that outside air comes into the cab. I have called other dealers and have been told that I should only feel air at outlets on the floor, dash, or defrost.

I bought this truck used in 2006. I have had several issues with the truck that seem to be very common problems with GMC/Chevrolet trucks. The instruments' lights are almost all out (gauges, radio, steering wheel controls, heater controls). The gauges themselves have went completely out and had to have them repaired by a aftermarket shop ($100). The wiring harness on the back of the heater controls burned completely out ($75), three other people I personally know have had this same issue. The air bag sensor is bad, which I refuse to pay $250 to have replaced, so I'm not sure if the air bag really works or not.

Went to get out of truck and the inside door handle wouldn't work. I think it's bull that it costs $800 for the part for a door handle. I just had back surgery and can't really afford a cost like that. My truck has 63,000 and I live out in the middle of nowhere and the truck has all highway miles. Not like I live in town where it is used constantly. Really a safety hazard if you need out in an emergency.

I am currently the owner of a 2001 GMC 2500HD Sierra pickup. I purchased this particular vehicle in October of 2006 from Spearfish Motors, a GMC/Jeep/Cadillac dealer in my area. During the purchasing phase of this the vehicle I expressed my concern about rumored complaints regarding the transmission and transfer case in this model of pickup. I was told by the dealership that the system was “bullet proof” and that I would have nothing to worry about. Since that time I have had minimal issues with this truck other than normal wear and tear that I have had to pay for out of my own pocket. With that stated, I have had no complaints with this truck until now.

FRAME rusted out - we won't mention the rusted brake line issues and costs associated with those. This truck only has +/- 30,000 original miles on it. Brought it in for routine maintenance only to be told the rear end frame has rotted out. The shocks no longer have connecting points to the frame; was told cannot be repaired and frame could crack due to the weakness from the excessive rust. No body rot, truck is otherwise mechanically good. Now need a "new" frame or a NEW truck... Either way I'm out a truck without a lot of $$$$$. I have never heard of a body being good/no rust and the frame rotted out...

My 2007 GMC Sierra driver door only opens from the outside. The interior handle does not work. Anyone with similar problems or how to fix problem? Thanks.

Nothing but problems. All exterior door handles have snapped off and have been replaced, some of them twice. Every power window motor/actuator has broken. Every power door lock has broken. Cab leaks. Rear door fills with water when it rains. Headlights continually burn out. It's almost impossible to change them with poor engineering design/layout. Airbag sensor went out. Headlights now refuse to work at all, fuses, relay fine, some kind of power surge keeps burning bulbs out. Have to drive around using fog lights and high beams only. Interior trim pieces continually snap off. Exterior trim pieces were never put on correctly and hang off. The MPG performance was a lie, I'm lucky to get 16 mpg. This was a $40,000 truck. I try to always buy American. I guess I'm a Ford man now!

I was on my way to town, and fortunately did not have anyone with me. Our 17 year old daughter is practicing her driving, she has her L. Anyway, we live 18 km from town, I was halfway there when, I felt the truck move forward like it was in cruise control. I didn't have it on cruise, next thing I knew it took off on me! I now was in a vehicle that WOULD not stop, there was traffic I had to avoid and the truck accelerated to 150 km per hour!!! As I was nearing more traffic and people, I knew I had to do something. So I drove off the road. Before that happened I unavoidably clipped the back of a small car, she is alright thank God! But this could have ended tragically! The only reason I am alive is the impact of the car had shut everything down, as I went down the embankment. I am suffering back pain, my knees, emotionally. I haven't received a report yet as what happened. But I know this, I had no BRAKES!!! That's enough for me to know I will NEVER drive a GM vehicle again!!!

I purchased a 2011 GMC Sierra pickup and purchased it with running board rails and the factory cover that came along with the truck. After about 10 to 11 months the cover has been giving me problems. On after another. First of all it was not mounted correctly and it put a bind on to a point where the hardware started breaking on its own. When taking it in for service it has not been put in the computer system and all they were doing is putting a bandage on the situation each time. I then started having problems with the paint cracking on the exterior of the bed cover. Again it was taken to a body shop kept for almost a whole and when returned to me I was told the problem was corrected.

Recently purchased a 2003 GMC Sierra 1500 from a GM dealer in Maine. I was asked to sign a waiver that I was aware the truck needed brake work. The brakes felt fine and thought maybe the pads were low. Now I'm paying the price and replacing one line after another. Time to get rid of this dangerous vehicle. Our do nothing politicians should make GM replace every "cheap" brake line they ever installed! I guess they don't think that brakes on vehicles are that important to the public safety!

Have a 2010 GMC 3500HD SLE-2 4WD 6.0L Single rear wheel. Just turned 260K. Tow a 5th wheel 6 times a year. Carry 2 tons I the bed more than once a month. Added an extra trans cooler. Nothing but good things to say. Lost a throttle body at 125k. I limped to a GMC dealer. They had one in stock and repaired in less than 2 hours. GMC reimburse me my associated cost, Rental, labor, parts after filling out a form. The truck was technically out of warranty. After a rear corner hit, a parking accident, the autobody shop returned the truck to me with a bad transfer case module. It turned out to be the encoder and module. Allstate Insurance forced the autobody shop to pay for the repair. The thought was he never disconnected the BATTERIES while welding.

I bought a 2013 Sierra 3500 Denali from Alexander of Oxnard. After looking at my contract I noticed that they charged me 800.00 for something that was never installed on my truck. I went to the dealer and told them about the problem and they said you still owe is 600.00. I told them are you crazy. Why would I owe you 600.00 when I just put 9,000.00 down on this vehicle. They said they don’t know it’s just showing up that I do. So they said well since that part wasn't on your truck we'll just call it even since you owe us money. Are these people crazy what they are doing is totally illegal and they don’t seem to care. If you are in the same are as me do not buy from this dealership they are a bunch of crooks. Now I have to deal with all the legal issues but luckily my lawyer is taking care of everything.

2005 GMC Sierra 1500 4wd - Driving home from Little League game 6-14-13 with my 7-year-old, came into traffic in town and my brakes went mushy. Within a couple minutes, it went from mushy to 5% braking. Had to avoid several cars as I made it home about 2 miles by pumping quickly just enough to slowly down enough to make turns and eventually stop at the end of drive while downshifting. When exiting the vehicle, there was a pool of brake fluid eating through my asphalt driveway. All brake fluid had drained out completely rusted/corrosion area of all brake lines by bundle under the driver's seat. My mechanic says other areas are almost as bad in other areas in the rear. Now I'm looking at $500+ in line repairs. Lucky, I or my boy or others were not hurt or killed!!

I have had this 2010 GMC Sierra for 3 years. I bought it new in April 2010. I have had numerous problems. The biggest complaint is the rust! If anyone lives in snow country, they know! I have addressed this with GM several times and they do not care!

2000 GMC Sierra Classic 3500 pickup - I purchased this truck new in Sept. of 2000. Since I acquired the truck, there have always been issues with the brakes. There is less than 30,000 miles on the truck as of this complaint. The backing plates of this truck are rusted away, the brake lines have rusted through and failed twice (once causing an accident), the frame has an usual amount of rust for the use this truck gets and the blower motor has burned out blowing a 50 amp fuse under the hood. This truck has had very limited use, is not parked in an area of high moisture or salt exposure but is rusting away and this has been a safety issue with the brakes. There was also a safety issue with the tailgate straps that hasn't been corrected after a recall because they could not find the proper length tailgate straps.

My brake line broke while I was driving. I did not get an alarm informing me that there was something drastically wrong with my brakes till the line actually broke. I had just dropped off my camper to the dealership and was on my way home. I hate to think what would have happened if my brakes would have gone out while hauling my camper. My grandkids are my world and I could not believe that GMC has been notified of this problem and has not warned its owners. Hopefully, something will be done to correct this issue before someone loses their life. I have two GMCs and will not purchase another. This is a serious issue.

2008 GMC Al-Terrain - I took my truck in for the dash cracking in two places. This exact same thing happened on my 2007 Tahoe and I got it replaced free of charge because of the numerous threads across the internet complaining of the same problem. The dealership stated GM wanted to charge a $100 deductible to replace the dash. Considering this is a defect in the craftsmanship of the product and the fact that it happened to my other vehicle and many others, why do I have to pay a deductible? I need some resolution with no out of pocket expense because this is a known issue.

2006 GMC Sierra SLT Z71 off road - This truck has been a pain since I purchased it new in 2006. The front bearings both went out, one at 30000, and one at 40000. The air bag sensor went out ($300); the heater blower, module, etc. went out ($600); the doors sound like they are rubbing when opening and closing but can't seem to correct it, and misc. other items. This truck only has 80000 miles on it, but I am ready for a new one. Do you think it will be a GM truck? Think again. PS. I have been a GM truck owner since 1988. GM knew about the heater problems for years but did nothing. This was reported in Consumer Report magazine.

I am the second owner of a 2003 GMC Sierra 1500 Z71. I bought the truck with full understanding that the brake lines looked quite bad for the year model vehicle. I previously had a 1999 Z71 with nearly 200K miles and the lines didn't look nowhere close to the sorry condition these were in. I have owned my current truck for a little over a year and I have put only about 4,000 miles on it because of the fear of the lines rupturing. I have been driving it with caution, even though the brakes felt a little spongy.

I own a 2009 GMC Sierra and the wheel covers keep coming off the vehicle. The first cover came off when the truck was under warranty and GM replaced it. The second cover came off after the warranty expired and GM agreed to replace it. When the first cover came off, I showed a technician at my local GM dealership that all of the wheel covers were loose and would most likely come off. They said, "We will deal with it when it happens." Recently, a third and existing wheel cover came off the vehicle and the local dealership will not replace it. The dealership told me to contact GM Customer Relations. I contacted them and they stated that their final decision is to not replace the wheel cover. I stated to them that this problem first started when the vehicle was under warranty and, furthermore, it is a safety issue that should be addressed and resolved by GM. I feel it is a safety issue because if one of these covers should come off when the vehicle is in motion, it could seriously injure anyone in the surrounding area. I stated my safety concerns to GM and they still responded with their position to not correct my wheel cover issues.

I purchased the 2006 2500HD diesel pickup new. The truck has had poor braking since new and the dealer has always said it functions normally. I have had the dealer do all the maintenance on the truck other than oil and filter changes. The undercarriage of the truck including all lines, brakes rotors, hubs has been rusting since new. The underside of the truck looks like a 20-year-old plow truck. On 12-6-2012, I was driving on the highway in traffic and then experienced a complete brake failure. Somehow I did not hit anything and was able to get to the shoulder and coast to a stop (very lucky in NJ traffic). The brake lines blew. The truck was towed back to the dealer and they find the lines are gone, as well as the rotors that they replaced about 2 years ago. The pads are still in great shape but the rotors are rusted beyond usability. Looking into this, I find I am not alone and would like to know if I can get info on the issue including - is the problem fixed in the new trucks and is compensation available as the truck is on its way to the rust graveyard with the sheet metal rusting from the underside also.

Failed, rusted brake and fuel lines on my GMC Sierra 2001: Two things started to happen: 1) The truck when coming to a stop of a speed of less than 25 mph started to lose its brakes and feel spongy. This continued until I got it in the shop which was about two days. 2) The truck started to run very rough and the engine light was coming on at the same time as well.

I own a 2003 GMC Sierra 2500HD. I bought it used with 30k miles. 8k miles later, the transmission started making noise. I took it to a shop. They said it needed to be rebuilt and gears were badly worn. Then at 40k miles, the differential started screaming - pinion bearing melted. At 50k miles, air bag light came on - bad front sensors. At 60k miles, a guy stopped short in front of me. I pressed the brake pedal, and the pedal went to the floor - two front brake lines ruptured, and the brake lines rotted. I've had enough with this truck. This is my first new truck. I have always had older trucks with no problems. I am never buying a newer truck ever again.

GMC 2500 Pickup: Small metal fragments from the block of my diesel engine broke off & went in the oil pan & were pulled into the oil pump & seized it. Small nicks in the blades & outer casting are visible & I'm sure the on-board computer recorded the failure. We have the pieces & with a video scope, you are able to see where they broke off from. The truck has less than 90k miles. GM, I'm told, has changed the direction of the threading for the oil pump so that the pump doesn't just stop as mine did. I'm not sure as to what direction to take from here. I didn't take it to my GM Dealer because of original estimate for repair. However I have not given consent to reassemble the engine so a GM rep. could examine. I'm not sure I want to take a risk of placing that engine back in the truck for fear of more fragments causing damage again. We are at about $2,700 at this point but a new engine would be very expensive.

Truck has been back to the dealer 3 times for the same problem. The truck is still not fixed. The roof leaks, headliner is stained, truck stinks after the rain and you can hear the water slosh around as you drive. Cruise control was worked on once and now works when it wants to. Sales Department at Mossy has helped me out a bunch (got me cars to drive while truck was in the shop). Service Department sucks. That's 25 years of GM products, only 2 other brands in those years. I currently own 4 GMs. The one I spent the most on ($50,000 truck) that I special ordered rains on me when I drive after it rains.

We own a Garage Kept, 2005 GMC SIERRA HD, 2500 6.6L turbo V8 diesel with a 5speed, automatic Allison Transmission. It only has 41,000 actual miles. We drive it on an infrequent basis. We began to hear a "whining" noise when driving at any speed and on any road. Since we are aware the vehicle is out of factory warranty and we didn't purchase an extended warranty, we took the truck to a local transmission repair garage on Thursday, 09/27/12.

My 2008 GMC Sierra Denali has had quite a few problems. First, I have had to replace each door handle on the vehicle. Now, I have had to replace the body side moldings. Both have been because of poor quality/design. I will never buy GM again. They now tell me that my vehicle is out of warranty and I am out the $1,200.00. Their customer complaint process stops with someone reading a script.

I purchased a 2012 GMC Sierra 1500 and that was my first mistake. The truck has 7,000 miles. The truck has stone chips all over it. I put mud flaps on it at 400 miles. I feel the damage is from the Bridgestone dealer of tires that was put on at the factory. I called GM customer service - what a joke. I took it back to the dealer. The service manager agreed that the tires are the problem. The service manager has the same truck and has the same issues that I do with my truck. A GM rep looked at my truck and told the service manager to check and see if I bought the Paint Protection Plan and to see if that would cover it. I will never buy a GMC again.

2003 GMC Sierra, brake line corroded/burst - Wife applied brakes and the pedal went to the floor sending her through a busy intersection during a red light, luckily, without consequence. She had to then slow down by downshifting the auto trans and then coast to a stop. When I got there, I found one of the five lines feeding the ABS control completely burst and the other four severely rusted. She was about to head down a steep hill and would have surely ended up in the Kennebec River. Lucky it failed when it did.

The speakers are out of my 2007 GMC Sierra truck crew cab, except for the front passenger's side. This truck is 5 years old and has been babied with only 78000 miles. There are a lot of complaints about this truck's radio speakers going out, but no recalls are noted.

I bought a new GMC Sierra on 10-12-11 from Great Lakes GMC Buick in Ashtabula, Ohio. On 8-4-12, I noticed two paint bubbles on the driver’s side door. Upon further inspection, I noticed obvious signs of body work having been done on the door. The body work was getting rough and failing. I took the vehicle back to the dealership and ** looked at the door. He agreed that there had been a repair made on the door, but there was nothing to indicate that it was the dealership that made the repair. ** also stated that it might have been repaired at the dealership, or it might have come from the dealer that way.

The brakes on my husband’s truck (2002 GMC Sierra 1500) are rusted so bad that he just about ran through a store when his truck would not stop. There is brake fluid coming out of them. Now, this is crazy as this truck is only 10 years old and should not be having rusting issues, especially with a part that is so important.

The speakers on the doors of the truck (2003 GMC) are junk, they are falling apart. The truck only has 90,000 miles on it .You can't play them because they are junk. I guess that is what we can expect from General Junk Motors. I was a GM man; no more. Your toilet paper auto company tells me how much you think of quality.

Pitman arm is worn at 45,000 miles on 2006 GMC Sierra VIN ** causing premature tire wear. The arm was not hardened properly. I see recalls on this problem, but I was told my truck was not on the recall list. I have always been satisfied with GMC in the past. Thank you.

2000 GMC truck not starting/ 2005 Impala ABS/Traction assist - First of all, the 5.3 liter engine. What a pathetic joke. The way this engine rattles and clatters, I should run diesel fuel in it. Let's eliminate the piston skirts and run it. These engines should have been recalled by GM to completely replace blocks, heads and pistons, but instead, we'll leave the consumer to buy a replacement engine for them - "junk".

Corroded wiring harness above the spare tire. The 2008 GMC sierra 6-year bumper to bumper warranty is not covering from bumper to bumper! Bumper to bumper! What does that mean! The spare tire rusted in place! It is only 4 years old and GM won't take care of me! The problem is also causing the check engine light to come on. The driver side door lock won't work anymore and many other electrical codes! I have to pay for everything! I owned GMC all my life and was a loyal customer until now! I plan on taking this to court!

I bought a new 2007 Sierra HD 4x4 pickup in Minot, ND. At 30,000 miles, I had nothing but trouble, all electrical problems. It was hauled to Williston, ND the first time. They put new ignition. It lasted about 2 weeks. I took it to R&R 3 times, all wiring problems. He would not work on it anymore. I hauled it to Gem City Motors. They put a new fuse box in. I drove 1 mile and it quit again. I hauled it back again to Gem City Motors. This time, it was a ground wire. It worked about 6 months. Now, it won't start again.

What a piece of junk! This 2003 GMC Sierra 2500HD Duramax pickup truck has run the gamut of problems and has cost me untold hours of lost time and money. First, the Allison transmission lost all but the 4th gear. The dealer (Asplund) gave me a loner car, which is not a pickup, for 3 weeks. The truck had to gone to Allison for repair! The satellite radio went out radio and the antenna was replaced. I had the truck for 1 week and went to pick the truck up. The radio did not work. I told them to keep the truck and give me a loner car until the problem’s fixed. It’s another week without my truck. The antenna went bad. The truck was towed twice for injector problems and it took 3 weeks to fix.

My GMC Sierra 1500 had brake line failures from rusting. There were two occurrences of brake line rupture. The first rupture was at 73,000 mile. The second rupture at 76,300 miles. The vehicle nearly turned on its side to avoid a crash in the first occurrence. A near collision with a second vehicle with a car carrying adults and children was narrowly avoided as a result of complete brake failure due to a rust-ruptured brake line. GMC refused to pay for brake repairs, which according to a GM dealer will cost me nearly $5,000 just for after market parts. There are currently over 1000 complaints of GM vehicles in which brake lines and connecting brake parts are rusting out.

I have a 2008 GMC Sierra that has had 3 door lock actuators go bad. The first with 7,000 miles; the second with around 28,000 miles; and now the third with 35,000 miles. There were no loss or injuries with this problem, but potentially secured firearms could have been obtained by children or criminals when the locks do not secure. The safety of auto locking doors when the vehicle is in gear is a benefit to the occupants from strong arm entry and to secure children while in travel.

2001 GMC Sierra - While stopping at a red light, the brake pedal went to the floor. Luckily, no one was in front of me. I went through the red light and I had to use emergency brake which did not work well to stop. The brake line was rusted through on the driver side rear just under the bed and I see rust along other portion of the line.

I recently purchased a brand new 2012 GMC Sierra HD truck. After one day and 200 total miles, a lifter/piston noise occurred very loudly. So I checked the oil level and it was fine. Then new 93 gas in and that didn't work. First thing on Monday, I took back to the dealer for assessment and I had to leave it. The next day, I received a call back from the dealer and they said the oil pump needed to be replaced. Really? The truck now has a total of 390 documented miles and a new oil pump installed.

That year seems to be the worst for that type of rust coming from the inside out, no way to prevent that unless you rust proof first on the inside. Bad, real bad! Mine has 99, value is shot because that lack of quality or the steel used. This is the wrong kind. I ran a steel slitter for 25 years. I know what can pass when there are deadlines to meet. It won’t show up for a few years down the road once you paint and ship it. I want GMC to install new rocker panels for me and my truck.

1999 gmc 2500 abs already stopped working. Was pulling out of my drive way and brake pedal went to the floor. Luckily no cars were coming down the road. Luckily no accident. Also my fuel line was rusted going to the fuel filter and the gas tank straps need to be replaced.

How can General Motors grasp the concept of quality?

I have 2008 GMC Sierra 2500HD loaded bought new. This is about 3rd GMC Sierra and I'm upset it's just less than 4 years old and the left front and rear door actuator have not been working for many 6 months. I mention it to the dealer and they gave me quote to repair but it's a lot of money. Searching for the parts and I keep coming across complaints of the same problems, so should there be a recall on these actuators since they knew for the 2008. I never had a problem with my other GMC Sierra's and they were before 2008. Also, there is not any aftermarket actuators out there so I believe there might be problem with them. Just what some information on what my next step should be.

I am a life long GM consumer, even had a Chevy Silverado Ext Cab (1992) get over 498,000 trouble free (starter, water pump and alternator only replaced) miles on a 350 CID engine. My current 2008 (purchased new) GMC Sierra Quad Cab with 5.3 L has two problems I see so common on the internet I wonder why there is not a bulletin or recall.

While driving my 2004 GMC Sierra with 48,014 miles on the odometer, the brake pedal went on the floor. Further investigation revealed that the l/f brake line burst. Closer inspection revealed all the brake lines are ready to do the same. Besides that, the frame is flaking as is the upper & lower control arms. The truck is 2wd, not used much at all (48,014 miles), not used in the winter, yet mine & thousands of other people's brake lines have rotted. GM has a responsibility to fix this problem before someone gets hurt or killed, if someone hasn't already. I called local GMC dealer and they said there is no recall and it would cost well in excess of $1500 to fix the issue.

An on-going problem with the steering column. On the day I picked up my 2004 GMC Sierra 1500, I felt a thump in the wheel. I asked the dealer to look at it and they used a grease packet authorized by GM to fix the problem. 50,000 miles later, the problem reappeared but much worse. That problem was corrected by GMC at no cost. At 94,000 miles, the problem has come back and worse again. I took it to a dealer and he indicated with a “laugh" that they will never do anything, meaning GM. The dealer gave me the 866 number and I spoke with a female named "Charlie," who began to recite the mileage as their reason for turning their eye from an apparent ongoing problem.

I have a 2004 GMC Sierra Event with 84,375 miles in it. While at our town dump on the 2nd of November of 2011, I proceeded from 1 drop off location to the next (as usual), when as I slightly depressed my brake pedal to slow, the pedal went right to the floor. I almost ran into another vehicle, had I not depressed my emergency brake. T here was nowhere to turn to as vehicles were everywhere. Wow! Not knowing what was wrong, I continued to the next drop off point, with virtually no brakes.

Brake lines are all rusted. These must be made from some substandard recycled garbage. People can get killed when these start leaking and popping under pressure. Parking brakes are useless on these due to inferior design. Obviously GM does not care because nothing has been has been done about it.

I have a 2003 GMC Sierra 2500HD 4WD king cab, completely loaded pick up truck. On my way to a job interview, traveling along at 55 mph, I was approaching a 4-way intersection and signaled to make a right turn. I touched my brake pedal and it went within an inch of the floor. I was unable to make the turn and went right through the intersection. There was still maybe 10% brake remaining and within 25 to 30 ft, I was able to come to a stop. I too was unaware of a problem with brake failure in this make & model vehicle.

I bought a new 2011 GMC Sierra 3500 to start a business with hauling cars. The truck only has 6,000 miles on it and has been in the shop 7 times for the same problem that the check engine light comes on and the truck goes into reduced engine power mode where you can't go over 20 miles per hour and needs to be towed to the shop. This is destroying my business and me financially, not to mention, all this stress is affecting my health.

I've owned GM cars for a long time. I consider myself a second generation GM consumer. My complaint is that my current truck, 2008 GMC sierra, is giving me issues with all the power window switch and also the door lock actuator. This is an on going problem since the first day of purchase. I've been to the dealer while the vehicle was still under warranty. But I know it's out of warranty and still have the same problems. I feel this is not fair.

I bought a 2001 GMC 3500 Serria dully from a local GM dealer. I really had a lot of respect for this dealership and I never would have thought in a million years they would do me wrong, but did I ever get a wake up call. I talked to the service manager before ever buying the truck. He told me it was in great shape. So, going on his word, I bought the truck only to find out it had busted head bolts, the power steering pump was bad, brakes were in bad shape, the belt tensioner was bad, it needed a new muffler, plug wires were rotten, plugs were old and bad, and they sold me a power train warranty that, when asked, did not cover any of the problems I now had. The dealer has really done me wrong. When asked, they tell me, well you should have driven it more, taken it out, and had it checked out. I was a great guy when buying it, now they don't know me,
