GMC Complaints

i was driving on the highway and the truck just shut off and rear wheel locked up almost caused me to wreck the truck. got truck pulled to side of the road finally after steering got real tight and very hard to steer to side of road. truck would not even try to start and engine warning light popped up on dash. i had to get truck towed for $243 to turner gmc in new holland, the dealership said it was a known issue since they had 2 trucks in their shop with the 6.2 L engines getting replaced. this was a very scary moment for me and now i have nothing to drive out money from towing and dealer told me it could be a few months before i get truck back. now i will have to pay for a truck that dont run at all.

During the first approximately 10 minutes of most drives, the vehicles speaker systems intermittently cuts in and out. This includes the turn signal audio and seatbelt chimes. It does not happen on every drive, I would estimate that about 2 out of 3 drives this issue occurs. All sound will cut out for about a half a second up to 2 seconds. After I begin the drive this issue will go away usually within 10 minutes however sometimes it is quicker than that. I have not taken the vehicle to be looked at due to others stating the dealer has no fix for the issue at this time. The turn signal and seatbelt chime cutting out can create confusion and may cause occupants to forget to buckle their seatbelt. No warning lights or messages have appeared in relation to this issue

Lifters failed and cam shaft was busted. Standard issues with 6.2L engines. Was traveling down highway and vehicles was shaking violently. Inspection report available. Has been inspected by GM service center. No symptoms or warnings prior to failure.

The contact owns a 2004 GMC Yukon. The contact stated while driving 45 MPH, the vehicle started losing motive power. The check engine warning light and another unknown warning light were illuminated, and a message was displayed that the gas port was reducing power. On a separate occasion, the vehicle started to lose motive power and then the vehicle started to shake. The vehicle was losing power and shaking until the vehicle was turned off. The vehicle was restarted and drove normally for six months without failure. The vehicle was taken to an independent mechanic where it was diagnosed with throttle body failure; however, the failure persisted. The vehicle was repaired but the failure persisted three more times with different diagnoses. The vehicle was taken to other independent mechanics however, the cause for the failure was not yet determined. The vehicle was not repaired for the most recent failure. The dealer was not made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 123,000.

My vehicle started making a terrible noise. I had it towed to the nearest GM service center. It was determined that the vehicle, a 2023 Yukon Denali (less than 26000 miles) needed a new engine due to thrust bearing failure causing the engine block to be scored and contamination of debris internally.

When it rains(or car wash) my power locks don't work. I get locked out of my car. My car reset itself in the middle of an intersection(like I turned it off and back on again). One of my gauges is always not working. The sunroof doesn't work right. Water is getting in the electrical area somehow. I've taken it to two chevrolet dealerships, but no help.

On two occasions while driving at low speed, my vehicle braked on its on a pulled hard to the left; the stabilitrac indicator also popped on briefly. I went online to determine if there were any recalls on my vehicle and found that one of the recalls on the 2016 Yukon was the exact issue happening with my vehicle. I checked my VIN and found that my vehicle was not one of the vehicles with this issue. I called GM to see if my vehicle had just not been published yet. I explain the situation too the customer service person; she understood my situation and informed me that until my specific VIN in identified with this issue, there's nothing that can be done. I'm thinking that until an accident happen because of this issue, there is nothing that can be done. I read that my issue was a problem with the EBCM, which needs to be reprogrammed. I thank you for any assistance with this issue.

The contact owns a 2020 GMC Sierra 3500. The contact received notification of NHTSA Campaign Number: 24V797000 (Power Train); however, the part to do the recall repair was not yet available. The contact was concerned about the remedy repair not being adequate to repair the vehicle. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

While driving on the highway the engine just shut off with no warning or other indication of problem. The dashboard computer instructed to restart the vehicle, which it would not restart. Managed to get to the side of the road. But the vehicle was unresponsive. After about an hour the lights in the rear of the vehicle flickered, so I attempted to re-start -which it did, and was able to drive the vehicle to the dealer (about 20 miles away). Where the car remains today. The incident occurred Feb 2. Took the dealer until 2/6 to advise me that the engine would need to be replaced. At that time they indicated they would need to car for about 2 weeks. I contacted them on 3/3 and they informed me they had no idea when they might be able to get the parts to replace the engine - there was a 3,000 engine backlog? Clearly there is a major issues with these engines; how are they allowed to continue to sell these vehicles, and allow current owners to operate them without a notice? While I was fortunately able to get to the side of the road - have in the car lose power suddenly lose power is clearly a safety issue!

The contact stated while driving 70 MPH over a bump in the roadway, there was a huge cloud of white smoke coming from the vehicle and the vehicle started to lose motive power. The check engine warning light was illuminated. The contact pulled over to the side of the roadway and waited for a tow truck to arrive. The contact attempted to start the vehicle again, but the vehicle failed to start. The vehicle was towed to the dealer where it was diagnosed with engine failure due to coolant mixing with the engine oil. The local dealer was contacted; however, the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 6,607.
