GMC Complaints

I was notified of the air bag recall in June 2023, and no action has been taken on this problem yet. My concern is, of course, if I'm an accident and the air bag deploys and metal is scattered thru out the inside of the car the end result will be disastrous to whom ever is inside my car.

The contact owns a 2021 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as needed and made an abnormal sound. The contact assumed that the sound was coming from the transmission and the vehicle was taken to a dealer. The dealer diagnosed the vehicle and suggested that the failure might be a pulley or a rod bearing failure. The contact took the vehicle to another dealer who confirmed a rod bearing failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 46,000.

Backup camera continues to intermittently fail even after recall remedy was performed. When placing the car in reverse, the backup screen goes black with a warning symbol on the screen that the camera is not working. This has happened intermittently for the last couple years. I've taken it to a GMC service center 5 times for this issue (3 of these visits were after the recall remedy was performed). The service has fixed the issue but it only lasts for a short time before reoccurring.

While driving, the infotainment system will suddenly increase volume to 100%. Have had this happen 4 times. Unable to turn sound down the last instance (or turn it off). Was able to find a safe spot to park and turn the vehicle off. This did nothing, as the radio would not turn off regardless of what I had done. After roughly 5 minutes of the vehicle being shut off, the radio finally turned off. No matter how many times the truck was turned on and off, the issue persisted. The only "fix" that worked was to let the vehicle for some time, which seemed to reset the system. THIS IS A MAJOR HAZARD AS HAVING SUDDEN SHOCK FROM VOLUME ISSUES IS EXTREMELY DANGEROUS. The sudden increase in volume nearly caused an accident on the road (each time). Vehicle is being brought to a dealer today to figure out the issue, but I see that it has been reported in several forums online with no fixes appearing to be available. Prior to the issue, there was no other issues or prior symptoms to alert of an issue.

While driving the car, the glass sunroof spontaneously exploded. It was NOT associated with a rock strike, no other cars were nearby, and the vehicle was not under an overpass. The noise was extremely loud, similar to a gunshot. The sun shade was closed, otherwise broken glass would have showered down on the passengers.

The contact owns a 2022 GMC Canyon. The contact stated that while attempting to start the vehicle, the contact became aware of a failure by removing the key from the ignition. The contact stated that in 15 to 20 minutes he was able to remove the key. The contact had to restart the vehicle several times and switch gears until the key was removed. There was no warning light illuminated. The vehicle was taken to the dealer where the diagnostic result was undisclosed. The contact was informed that the ignition switch needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 36,746.

The contact owns a 2019 GMC Acadia. The contact stated after parking and turning off the vehicle, an alarm sounded and the message "Shift to Park" was displayed. The contact stated that the failure had been recurring. The contact stated that on several occasions, the failure required that the vehicle be turned off and restarted to remedy the issues. Additionally, the contact continuously shifted to park(P) until the vehicle responded as needed. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 62,000.

The contact owns a 2016 GMC Acadia. The contact was notified of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed that parts were not yet available. 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. VIN tool confirms parts not available.

Hello, I purchased a 2022 GMC Sierra AT4 2500 in August of 2022. I then purchased a 2022 Alliance Avenue 30RLS in September of 2022. The first time we took the Alliance Avenue out on a camping trip (October 2022), we had brake controller issues. The brake controller would suddenly disconnect and I would have an error on the screen saying that the controller was no longer connected, and the light would go off on the brake controller on the dashboard. At this point, we had no trailer brakes. This issue happened several times, and the controller would go offline and come back, sometimes within seconds, sometimes in minutes (up to 10+). Strangely, the lights and signals continued to work. After the trip, I brought the trailer back to our RV dealership where they inspected the brakes and said we were okay on that end. I then took the truck to a GMC Dealership who informed me that everything was good on their end... Next trip, same issue. Took the trailer to the RV dealership and they took the system down to the brake pads and said they didn't see anything, but they rerouted some brake wiring just in case. On the way home from the RV dealership, the brake controller continued to fail. Took the truck back to GMC, they found nothing. Had a 3rd party RV repair tech install a solar shutoff switch and replace the trailer side brake plug in pigtail to rule that out. The issue persisted. Took the truck to a Chevy Dealership, the found no issues. Took the trailer camping several times, same issue persisted, and we were in dangerous situations over the Colorado Mountains, having this fail multiple times over Eisenhower Pass and other mountain passes. Took the trailer back to the RV Dealership, they found nothing - took it to the Chevy Dealership, they replaced the truck bed plug-in. The issue persisted. The Chevy Dealership informed me there was a module replacement for the GMC 2500 2023-2024 trucks, but they could not do that for me.
