2022 GMC SIERRA 1500 Complaints

The factory Installed Trailer Brake Controller - The brake controller disengages the trailer brakes after multiple applications of the brake pedal. If the ignition cycle is stopped and restarted brakes are then reconnected. The Truck is equipped with a Max Towing package and factory installed brake controller. Prior to disengaging the trailer brake, a message "Check Trailer Wiring" appears each time the brake pedal is applied, then after multiple brake applied, the message" Service Trailer Brakes" message appears and the trailer brakes are disable for the remainder of the ignition cycle. I had the brake controller serviced at a GMC dealership In Hillsboro, Oregon following the first failure of the system, they advised me that the problem was the trailer plug on my trailer and advised me of brand and model number to install on my trailer. After I installed this new plug problem remained. I then to the truck to the dealership where I purchased the truck in Salem, Oregon. After an inspection there I was informed that it was a wiring issue with my Canopy and that they had fixed it. Again the problem wasn't fixed and the brake controller continued not to work. On my next visit for the same problem I was advised that my trailer was the issue and that the truck wasn't the problem. So I took my trailer into a top tier trailer repair shop and everything on my trailer was functioning as designed with no repair required. These 3 visits were over a period of 14 months. Over this 14 month period I had two close calls while towing my boat and trailer. What I have now learned is that the factory installed brake Contoller is not compatible with my trailer electronic brake actuator, even though all of GM promotional information says that it is. In addition none of the GMC service representatives were aware of this problem. I had to point out an obscure bulletin to them. by GMC failure to advise owners of the problem many drivers are being put in harms way. GM needs to inform

The contact owns a 2022 GMC Sierra 1500 Denali. The contact received notification of NHTSA Campaign Number: 22V903000 (Exterior Lighting) however, the part to do the recall repair was unavailable. 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.

I purchased my 2022 GMC Sierra Denali Truck back in November from Ewing GMC in Plano, TX. I am a roofer, and my career depends on my vehicle. I live in Plano, TX, and was driving 80 mph back from Lubbock, TX around 12 PM Friday 3/24/23, on the highway when a notification appeared on my dash saying I needed to press the "start" button. The truck completely shut off, making it difficult for me to pull to the side of the road safely. Once I had stopped, I put the truck in "park" and it was completely unresponsive and would not re-start. I had to wait over 5 hours for OnStar to get a tow truck and get my truck. It was eventually towed to Frank Brown GMC in Lubbock around 6:30 PM that evening. I live in Plano, TX, and had to fly back the following morning. GMC in Lubbock was not able to look at the truck until late Monday afternoon 3/27/23. The service manager in Lubbock said the engine appears to be seized up internally and they have suggested a complete engine replacement from corporate. It is now Wednesday 3/29/23. I am still without a loaner truck, as Ewing GMC here in Plano will not provide me with a loaner since the truck is not in service at that location. It is not my responsibility to get the defective truck back to GMC Ewing in Plano, as the truck is still under full warranty. GMC corporate, Ewing GMC and Frank Brown GMC are not taking this situation with any urgency, and I am now responsible for paying for an $85,000 truck that does not run and GMC has not been cooperative in resolving the situation in a timely manner. I am at a loss as to what can be done and how I can proceed to get this resolved ASAP.

The contact owned a 2022 GMC Sierra 1500. The contact stated that while the husband was driving approximately 20 mph smoke was suddenly present coming from the vents inside the cabin of the vehicle. After pulling over and stopping the vehicle sparks suddenly came from the radio console and the husband immediately exited the vehicle. The vehicle quickly was engulfed in flames and the fire department was called to the scene and extinguished the fire. During the incident, the vehicle was destroyed. A fire and police report was taken and the vehicle was towed to an impound lot. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the incident. No injuries were reported. The failure mileage was 11,373.

I bought a new GMC, I received 3 vouchers for computer chips to be installed at a later time years ago. They have not provided them. They are selling new fully equipped vehicles with computers chips just fine. Can you handle and have GMC install their backlog of computer chips? There are many safety features that DO NOT work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal. Thanks.

While driving down the road on two different occasions the volume on the radio went to full blast and would not turn down or turn off. This caused distracted driving and could potentially cause an accident. Dealer states manufacturer is aware of issue with no resolution at this time. No warning of failure and the first occurrence was February 12, 2023 and the second occurrence happened March 5, 2023.

The back-up/reverse cameras black out mid action and also once the vehicle is put in Reverse. During inclement weather conditions, a car stopped abruptly in front of me to avoid a huge pool of water on the highway and the forward collision braking system did not kick in and now the light is illuminated on the dash board and won't turn off.

There is an occasional burning rubber smell(weekly and daily) coming into the cabin of the truck from the Duramax engine/exhaust. The dealer was notified and they informed me from their bulletins on the matter, that they believe it is from a "wax" on the vehicle exhaust system when heated up. They informed me that their is no remedy or fix at this time. The smell and air quality that me and my family are breathing I believe is unhealthy and possibly toxic. I would like the GM to replace these components causing the issue.

I purchased this vehicle to tow a 7,600 pound RV trailer with Electromagnetic brakes. This truck has an integrated brake controller. The truck keeps giving error messages: Check trailer wiring issues. Brakes not connected, etc. I have troubleshoot the trailer wiring and replaced most of it. I still have the issue. Online I see many people stating similar issues. Supposedly my truck has an error code associated with the brakes but dealer is of not help.
