GMC Complaints

I loose brake pedal at low speeds seen gm has recall for vacuum pump but shows mine not in recall

I heard a ticking noise coming from the engine compartment. I took it to the dealership that I purchased the truck from and that have been using consistently for service. I was told that the noise was coming from a lifter on the driver's side of the engine and, on further investigation, it was determined that the camshaft had been damaged. I was told that it could seize up as I was driving and that my safety and those with and around me would be at risk. At 85,000 miles, the engine had failed and would have to be replaced. There was no prior warning or no check engine light and the vehicle has been in for oil changes and all maintenance at the dealership. The new engine cost me $15000 including diagnosis and towing.

Front air bag sensor part is not available. Part number 85597996 has been discontinued without a replacement. As such, I have no airbag system on my truck.

Pulled up to a stop sign, the engine shutoff and would not restart. Had the vehicle towed to the dealership. Received a call that the engine will need to be replaced. The code is a P0016. Same code as the other 6.2 L87 GM motors, but is not currently under the recall. They found no metal in the oil pan and the engine only has compression on cylinders 2 & 8. Make no mechanical sense. Before this, I had no engine lights, I had no oil burning, I had no smell of oil and the truck ran fine. No loss of power or any other issues.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at 60 MPH hauling a trailer going downhill, the engine seized. The vehicle was difficult to control. The message to “Shift to Neutral and Restart" was displayed. There were no warning lights illuminated. The driver attempted to restart the vehicle. The contact stated that the running boards were stuck outwards. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where the engine was replaced after two months. The dealer informed the contact that the battery was completely drained. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 67,500.

This vehicle exhibits the same failure described in NHTSA Recall N232426400 — spontaneous unlatching after rain due to water intrusion into the exterior tailgate release switch. I’m requesting a goodwill replacement under GM bulletin # N232426400 as the failure mechanism and part are identical. It has caused brake failure and nearly killed me because of battery drain while driving. All American Chevrolet of Midland Texas is refusing to solve the problem and says no recall is available.

The contact's boyfriend owns a 2017 GMC Acadia. The contact stated that while driving at various speeds, the vehicle jerked abnormally while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to an independent mechanic who was unable to determine the cause of the failure; however, the mechanic stated that the failure was related to the transmission. The contact called two local dealers about the failure, and both stated that the vehicle could not be serviced in the near future. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 106,000.

GMC customer care representative & local GMC service department supervisor unable to help. 2017 Acadia Shift to Park message. It’s Difficult to turn the car off. The vehicle refuses to acknowledge the park position. Potential rollaway hazard. You may inspect. Took it to GMC service & confirmed it is a prevalent issue: Transmission control 13534320 = gearshift assembly & Jumper harness 84733196. This problem has been recurring for several years and I have problem solved how to shut the car off. GMC customer care rep said it’s an issue with all 2017 Acadias and tried to help. The system deemed it complicated case & escalated it to a Supervisor. She read a “customer care” script. After talking, she admitted that realistically GMC would not help. Yesterday, she advised me to file a complaint with NHTSA. I read that 2 other states Ohio & Tennessee won class action lawsuits because of the hazardous shift to park issue. If GMC issued recalls for 2017 Acadia shift to park then my 2017 GMC Acadia should have been included. I have been waiting for the recall for several years. GMC admits the problem is prevalent in 2017 GMC Acadias. Would you please issue a recall associated with this issue and link it to my VIN. Thank you.

Break assist light comes on and brakes stiffen suddenly with no warning. Happened 6 times now in a 3 year span. Gotten it "fixed" each time but it keeps happening

The vehicle will loose all interior audio to include stereo, turn signals, and all other audio safety features for several hours at a time. GMC has done three repairs and still no resolution. Lack on audio impacts the safety of the vehicle. Has happened dozens of times and appears to be larger GM issue that is u resolved. Has occurred at least 20 times since I bought the vehicle 10 months ago.
