GMC Sierra Reviews

We bought a GMC Sierra and the vehicle quit on us two times and the third time it quit it was in our driveway and a service Truck from Bull Motors where we bought the vehicle came a loaded the vehicle and to it to Wynne Arkansas and it has been there for over two weeks. Some lady named Laka from GM called me today and told me she would be waiting for 14 days to see why the fuel pump has been on back order. I went online and found the pump myself. I told the lady from GM that I found the pump online and because it is taking this long for them to get the pump I probably won't be buying GM anymore and if they do not get the pump ASAP after it has been up in Bull motors for two weeks, they have just about lost a customer in the future.

I'll start right from the beginning. First issue was with the truck lurching when putting it into Drive. Took it to the Welland Dealership and no issues found. 2nd Issue. Three times I had to take the truck in to get the radio replaced, the screen kept going black. On the third trip back to the dealership they finally replaced the Radio. 3rd Issue. Right side bank needed new lifters, Replaced them. 4th issue. Left side bank needed new lifters. 5th Issue. I've taken the truck back for service engine light flashing, nothing was done. 6th Issue. The truck is back in the Welland Ontario Dealership getting another set of lifters done on the right bank of the engine. Keep in mind this is a 2021 GMC Sierra Truck. Where is the Quality????

We held off on writing this review because we didn’t want it to be colored by wild emotions. But we are both feeling so taken advantage of that I think it’s time to share our experience. After spending a long 12-hour day driving from New York to Ohio we noticed a problem with our GMC Sierra truck and knew that it was something that needed to be handled by a professional. With a quick google search we found Perrysburg Automall and called to see if we could get an appointment and he (John E.) said “come on in”.

I went in for high mileage services and oil pan gasket replacement. Upon arrival inquired if a veterans discount was offered. I was told that USAF doesn't count. Also I requested the oil pan gasket be replaced. It was leaking. I not only was disrespected for my military service but I was charged for a oil diagnostic and 2 oil changes. The transmission filters weren't mentioned or replaced with the "transmission service" and they were stock, so my truck is a 2015, 8 years old on those filters should be addressed.

I bought a new 2017 GMC Sierra. I noticed some irregularities with the transmission at times while driving. Specifically the truck would plunge forward while braking on a hill. The plunge was significant and I took the truck in a few times to the dealership. They claimed that they needed to reset the computer and the problem should work itself after driving. Unfortunately, the problem persisted and now I was told I needed a new transmission. But since the warranty had expired passed 67,000 miles I was responsible for the entire cost of replacement. I later found out that other Sierra owners experienced the same issues. I have bought 4 GMC vehicles but will never buy another GMC product again.

Between the transmission vibrating and shifting hard to a point where starting to drive slams into gear and is dangerous in a way that may launch you and your vehicle into danger. To the trained mechanics saying, "I see no problem", to the power running boards not working on either side after being fixed twice, to the phone app not working correctly or the half dozen sensors going off and setting off the alarm and killing the battery completely dead, to where a tow truck has trouble jump-starting it. Just poor quality either from the union workers with no pride or skill to the company trying to pinch a penny for their own pockets. I will never buy another GM product again.

I traded in a 2015. That Sierra had wonderful front bucket seats and the back seats weren't too bad. But the 2020 truck has the hardest back seat and the bucket seats are medium hard. I sometimes drive 6 hours in a day and I'm so painful when I finished.

I was on the phone for over an hour checking the order status of my new truck. All I got for a hour was representatives assisting other customers. Your call is very important to us. Yes The worst customer service I’ve ever experienced. I’m canceling my order.

I own a 2014 GMC Sierra piece of garbage. 19 recalls +! on this vehicle. (Check out NHTSA. Probably more by now.) They stopped servicing my recalls at 70,000 miles. Great. Could be safety issues that they refused to address due to having so many recalls on one vehicle. Then my transmission fell apart at 150,000 miles. That was $5500. And now my rocker panels have rusted through and need to be replaced.... $4400... for a 7 year old vehicle!! My neighbor's 1974 Ford pickup has perfect rockers and it sits outside all year every year. I will never buy another GM product.. and my father worked at GM for 43 years. What pathetic engineering to have such a defective vehicle. I have had Jeeps that were 15 years old that never had one issue, other than replacing brakes and tires. My next truck will be a RAM. Yours should be too, or a Toyota, or a Ford, or anything other than a GMC....

Horrible experience with a very expensive truck. 3 failure for same crap... trying to get GMC to replace the truck. Never in my life have I owned a more problematic auto. Stay away from GMC! They are producing unreliable vehicles that takes months of downtime. I have stage 4 cancer and this is the last stress I need!!!
