GMC Complaints

I purchased my 2022 GMC SIERRA XLT in February of 2022. I have had it in the shop 4 times for recalls. They couldn’t or didn't put an inspection sticker on the truck because I honestly don’t think it could have passed inspection. The truck sounds like a truck on Transformer when I turn it off breaking town like a robot. On yesterday which was 1/27/2025 while backing up to turn around the truck started dragging in the back like the breaks locking up, the same thing happened while turning into my driveway off a state highway with an 18 wheeler coming. GMC can’t look at the truck until February 10! This Truck was purchased new and it’s been nothing but trouble. Electrical system goes in and out Steering assist reduced drive with care, Engine power reduced, park assist on then off and truck making unusual noise. I waited 13 YEARS to finally get another brand new vehicle and this what I ended up with. My last new vehicle was a 2004 Honda Pilot. I had 459,000 miles on the truck no engine or transmission issues. I donated the truck to Goodwill. Therefore, I hope GMC understands my frustration when my daughter’s 2019 Kia Optima is out performing my 2022 GMC XLT truck. The back breaks are dragging and locking up, it appears the gears are getting stuck and I can’t back the truck up or go in reverse without the struck staying stuck, then jerking vigorously and problems with the wheel turning to the right the truck get stuck or stall!

Transmission, rear wheel lock up issue. Dealer performed recall notice work. Truck still has same issue after dealer visit. When issue starts, feels like you ran over something in the road, All warning lights are on, loss of power to engine and the engine did quit working once. Door locks continue to cycle repeatedly, multiple screen warnings appear on dashboard. It appears that everything that could go wrong happens at once. Have heard transmission valve control modules is a major problem with GM 10 speed transmissions.

2020 GMC Sierra Denali – VIN [XXX] On [XXX] while driving the 2020 GMC Sierra to work I noticed a strong gasoline smell inside the cabin. I immediately returned home and parked the truck in the street. Inspecting the driveway where the truck was parked over night, I notice large gasoline spot. The following day I had the truck towed to Boyds Tire & Service center to have the truck inspected. On January 20 Boyds called me and shared the truck had experienced a failure of the High-Pressure Fuel Pump which has been recognized by GM as a recall under N192283991. I called a local GMC dealership about this failure and they stated it would cost $300 to review and would not perform any work under a recall. Also, the dealership stated they could not service the truck for another two weeks, which I cannot be without the truck that long. So, I had Boyds perform the repair the same day. Unfortunately, GM has not listed my truck on this recall. This is the reason for my submittal and request for a full refund of the repair service due to the failed part. This being a very High Risk of Fire and injury and death, I decide to have the repair completed immediately. I have since contacted GM about this incident they will not consider my request for recognizing and reimbursement for service repair.

2024 gmc Yukon with less than 2,000 miles decided not to start one day. Had a tow truck come to the house and pick it up to take to a local shop to get a new battery. Replaced the battery and the battery shop delivered to car back to our house and was totally fine…the next day we went to start it and again the battery was toast. So, got another tow truck to deliver to the dealership and had it checked out, the dealership says there are 12 codes popping up and they can’t figure out why the batteries are not holding at this point. This is a diesel Yukon. We had a 2022 Escalade that the motor went belly up on us 3 times before we bought this diesel Yukon thinking this problem would go away but I guess I was wrong. I will be returning this Yukon to the dealership and doing a buyback. We have been stranded way too many times with these gm vehicles and I’m starting to loose trust with General Motors.

Engine knocking and metal in oil. Been to the dealership and even though it's under warranty they will not act on it due to no check engine light present. It's making it difficult to trust driving the vehicle anymore because of the thought of the engine shutting down without warning anytime. This complaint is documented and confirmed by a dealership. They made me pay the check out fee and recommended i keep driving the vehicle until the motor locks up.

I was driving on the highway and my truck went black and engine stopped no power to truck. It was very scary. I pulled over and it was in Neutral and somehow got it into park. The car never would turn over. The truck is at midway motors with metal shavings in the engines. They say it locked up and needs replaced. GM is very difficult to work with and won’t give us any information. I’m scared of the truck.

Engine locked up while driving down interstate. Found out it’s the 2nd engine that has been replaced. On its 3rd engine now. GM 6.2L

After taking my truck in for recall fixes. I received a message on my screen saying that I had 94 miles until I was limited to 65 mph. It said check DEF system. After taking it in the dealership charged me to fix the computer. Known defect yet they charge for it.

When I am driving in town I have an indication message that comes up and says engine power reduced

My car lost oil while I was driving. I also lost power. I had my car over to a garage and the mechanic diagnosed it was a ruptured rear main seal caused by a frozen PCV system. GM knows about the problem but has not recalled it. It is very expensive to repair. And because the manufacturer knows about it but never told the consumer, is fraudulent.
