GMC Complaints

I am writing a complaint in reference to the already issued recall number 23v334, for the acadia's and their airbags. It states that if the remedy is not taken care of or whatever the wording about a timely manner, to reach out and this recall was issued in May after already being aware for some time, and now we are approaching the one-year Mark and they still have absolutely no remedy available for the Acadia and they are Slow Rolling each model out to save money. I am literally driving around with a ticking time bomb in front of my face with the potential to kill me according to its own wording and according to the own manufacturer reading back the identical wording while they're telling you that they have no option available there is no new airbag that they have worked on in the 8 plus months since recall, and there's literally nothing I can do to ensure my safety so I am officially lodging another complaint for the safety of this already known issue that is not been remedy and whereas there appears to be no active and serious engagement and producing something. This is completely unacceptable and something needs to be done about it as there are plenty of people out here with the same potential Hazard right in front of them each and every day they're entering this vehicle.

Trailer brake controller that is built into the truck intermittently works when towing a trailer. I will be towing down the road and all of a sudden I will get a warning on my gauge display that says “check trailer wiring” and the light that indicates that the trailer brakes are working goes out. Meanwhile, all of the lights on the trailer still work. After about one second, another message appears and says “trailer brakes connected” and the light on the brake controller comes back on. When this happens, the larger screen sometimes has a message that says “trailer brake gain recalled” but sometimes it says “brake gain not recalled”. When the message “check trailer wiring” comes on, the trailer brakes don’t work. The trailer brakes start working again when the message “trailer brakes connected” comes back on. You can feel this in the truck, especially when it goes off, on, off, on, etc while you are trying to slow down. You literally feel the truck surging as the brakes are intermittently being applied. I have taken the truck to a GMC dealership and they were not able to duplicate the issues since the issue only happens when the truck is hooked up to a trailer that has trailer brakes. I had a certified RV mechanic inspect the trailer brakes and they are working like they should. I hooked the same trailer up to a Ford F-250 and had zero issues. I hooked the same trailer back up to my GMC and immediately had the same issues. I am taking the truck and trailer to a different GMC dealership on March 11th to see if they can duplicate this and diagnose the problem. I called GM corporate customer service and they were basically no help. This is a big safety issue because the truck is not telling the trailer’s brakes to function like they are designed, which makes it much more difficult to slow down, especially going down hill. I have done a bunch of research on this problem and found numerous online forums on this topic, so I know I am not the only one experiencing this

In july 2021 the passenger side tail light stopped working. A certified GMC dealer replaced both tail lights. In Feb 2024 the driver side tail light failed.

Tailgate fell down when I had a trailer hooked up. I was parked, then backed up the trailer. Tailgate came down on the jack and scratched the tailgate. There is a recall on some trucks but mine says no recall. Sounds like same issue.

Two of the valves failed and the dealership told me it was likely due to a manufacturer’s defect.

My vehicle stops working while in traffic when the auto stop is engaged. The abs, parking brake, and dash flashes prior to the engine stopping. I have been to the dealership multiple times and they are never able to recreate the issue. The check engine light codes produced are P0014 and c0800-03.

The contact owns a 2023 GMC Canyon. The contact received notification of NHTSA Campaign Number: 24V133000 (Electrical System, Forward Collision Avoidance). The contact stated that while driving at approximately 45 MPH, the collision sensor lights flashed, and the brakes were applied inadvertently. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 2,800.

The contact owns a 2016 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was contacted, and it was confirmed that the part was 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.

Rear main oil seal is faulty. It caused the vehicle to leak oil to the point where it was dry. This is a known issue with these vehicles and could have caused catastrophic damage to the engine. Additionally, this can cause the vehicle to stop running and/or catch fire.

Transmission flares going into and out of second gear cause to vehicle to feel as if its about stall out. Especially on hills. I had a vehicle almost run in to the back of me because of the decrease in acceleration.
