GMC Complaints

My airbags have been under recall since May 2023 and they have not yet been replaced. My vehicle also doesn't appear on the priority list.

The contact owns a 2020 GMC Sierra 2500. The contact stated that when the vehicle was parked, the contact's husband noticed that rainwater had entered the rear interior of the vehicle. The contact stated that the rainwater had entered through the rear sliding window. In addition, the contact stated that the aluminum casing around the rear window had fractured. The contact stated that due to the failure, the interior of the vehicle had a moldy odor. The vehicle was taken to the dealer where it was diagnosed with a fractured window frame. The contact was informed that the rear window and frame needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The contact was informed that the repair would not be covered under warranty. The failure mileage was approximately 69,000.

The contact owned a 2019 GMC Terrain. The contact stated that while the wife was driving at approximately 60 MPH, the brake pedal was depressed and it felt stiff. The vehicle failed to decrease in speed and as a result, the driver merged to the shoulder of the road however another vehicle crashed into the front driver side of the vehicle. The driver was able to merge to the shoulder of the road where the road bumps were able to decrease the speed of the vehicle. The ABS warning light was illuminated. The driver, front passenger, and rear driver's side passenger all sustained headaches and received medical attention via an ambulance on the scene. No occupants in the second vehicle were reported injured. A police report was taken at the scene and the vehicle was towed away. The cause of the failure was not determined. The manufacturer and local dealer were not contacted. The failure mileage was 40,000.

When attempting to Shift To Park, the Power Train does not respond, an error message is displayed, and am unable to turn off the ignition or park the vehicle. THIS IS A MAJOR SAFETY ISSUE.

When starting the vehicle, I received a “reduced power” warning and then the check engine light came on. I was afraid to drive it to the service center, so It was towed. The repair center informed me that the timing chain failed and that engine will no longer start at all. I cannot afford to have the engine repaired no matter the cost because I’m still responsible for almost $6k of the loan for this vehicle, in addition to full coverage insurance required by the lender. Also, probably taxes as well because I now have a very expensive lawn ornament. Oh, and towing fees to deliver the ornament to the lawn. And then there’s the cost of finding transportation so I can actually work to throw money at all of those costs. Being buried financially because I put faith in this product is an injury and an expensive lesson.

When braking, the service trailer brake system message and service stabilitrac message appear on the dash and brake pedal gets soft to hard repeatedly and truck pulls from side to side violently as if one side of the trucks brakes are working and the other side is not.

The contact owns a 2018 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle briefly accelerated and decelerated erratically, after which the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle was able to restart, but the failure persisted, and the vehicle was unable to accelerate above 20 MPH. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 120,000.

On [XXX], my wife was driving her 2022 Yukon XL in [XXX] , when she heard a loud pop and realized her sunroof had exploded and shattered. Thankfully, the sunshade was closed, which prevented shards of glass from entering the interior of the vehicle. She was driving alone, had not gone under an overpass, and there were no other vehicles in front of her. There was no indication that a foreign object struck the glass and the remaining glass is clearly protruding outwards. A quick search on this issue revealed that this is not an isolated incident and has been noted by consumer reports and a previous NHSTA investigation. On June 20th, 2024, I contacted GM customer service. I was told that there are no recalls, extended coverage, or safety bulletins on the sunroofs. The customer service agent stated she had never heard of the issue and recommended that I contact my closest dealership for repairs. Repairs are estimated to be around $750. I am urging the NHSTA to reopen an investigation on defective sunroof glass and GM to issue a recall before someone is injured or killed.
