GMC Sierra Reviews

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,

I bought a new 2006 GMC Sierra 3/4T. At around 58,000 miles, the ABS kicks in at low speed. It is very dangerous! I am appalled that GM won't include all states in the recall. Why would Wisconsin not be included? I've always had a GMC truck. This will be my last! The whole brake ordeal is just one of many problems I have had. Every time you take a GM truck to the dealer, they tell me "oh that's normal". After receiving a bail out, is this how they conduct business?!

I have a GMC Sierra that has given me nothing but problems with the sunroof. It has been fixed many times, approximation 6, and now that it is out of warranty and it needs the same parts replaced again, I am told that I am out of luck. The mechanic who looked at it told me that it was made by a company called Lasko and that GMC only used for about a year because of their poor quality. They say they are American made, but their products are full of foreign plastic parts that don't hold up.

All I can say to you Ford people is that my GMC Sierra runs fine, has 90,000 miles, has had only routine maintenance done, and can still run from Ohio, cross country pass all Fords on any stretch of highway. I have sleeping disorder from all the Fords rusting as I try to sleep. I'll ry buying a GM the next time. My uncle worked for Ford 35 year and always bought GM, and he still enjoying retirement because he doesn't have to give it back to Ford for junk.

I had complete brake failure on my 2001 GMC Sierra 3500. Coming up to a crowded intersection this past weekend, I applied my brakes and the pedal went straight to the floor. I managed to veer off the road and force a downshift to avoid a collision. I would have used my emergency brake, but it is almost useless, even though that was "fixed" under a recall by GM.

I bought a 2009 GMC Sierra. From the very beginning, I've had a clunking noise in my transmission as I begin to accelerate. I was told (at first) that it was my yoke. Then I was told that the factory was working on a fix. I got a call from a rep who instructed the DLR to replace the yoke.

I took my GMC Serria truck in for service. My complaint was a clunking in the rear end. The service advisor told me that there is a factory defect on my truck. The milage on my 2009 GMC has just hit 24000. There has always felt like mabe I have gear issues. I was told that there's issues with the slip yoke binding causeing this to feel the way it does. According to the service advisor that this has been a on going issues. He says that my warrant on this is a life time. I just have to keep bringing it is when I get this clunking sound for lubrication. I feel that this should be fix now!! I have a towing package and do not even feel safe to toe any thing. I check other complaint on line and found this has been going on for years. My question If you know about this why are you still selling this truck. To me that is frawed.

I own a '99 GMC Sierra with 156K. The brake lines are extremely rusted to the point where after changing my front brake pads and rotors today, 6/18/2011, a line failed and burst when I was applying pedal pressure after bleeding a line. It burst on the driver’s side above the rear axle. All the lines are badly rusted and I may have to replace them all now. This is such an unsafe situation. What if I was driving and the line burst and I lost brakes, an accident and or death could have occurred, maybe mine! I think GM should be held responsible for these repairs. Why couldn't they use stainless steel? Extremely dangerous situation. All '99 and above Sierra and Silverado owners should be made aware of this potentially deadly condition. The economic damage I will know after I have my Sierra towed to the shop and get an estimate. Physical damage was averted thanks to fate. It burst after I replaced front pads and rotors while bleeding lines.

Inspection of vehicle disclosed fuel leak from fuel tank. Similar defects have been reported on various ocassions for the same year, make and model. Replacement of a new fuel tank. Fuel tank cost estimate by dealer is approximately $ 1400.00 without labor costs and environmental costs for disposal of tank and fuel. Tow truck costs $40.00. Personal transportation fees (Taxi)to residence $18.00.

General Motor's brakes stink. I own a 2001 GMC Sierra with 58,800 miles and had to replace the rotors, calipers and pads for the second time as they are all rusted.

I own a 1999 GMC Sierra 1500, I have a problem with my antilock brakes as i see many people have also, the antilock brakes would activate whenever i tried stopping and made the brake pedal very hard to depress, it got so bad that i had to remove the fuse for the antilock brakes.

I complained about ticking/knocking sound from engine. I have complained many times about this problem only to be told that the problem is not detrimental to the performance, reliability or durability of the engine. The noise does not have any effect on the longevity of any of the engine components.

I purchased a 2002 GMC Sierra 2500HD truck with an 8.1l V-8 engine new. After 600 miles the engine began to clatter loudly on cold starts. Two dealers and GMC Customer No Service Hotline all thold me their engineers had determined the noise would have no effect on the life of the engine and it was "just a characteristic of that engine."
