When towing our 5th wheel RV we started getting messages on the computer that the trailer brakes were not working due to an issue with the brake controller. Trailer brakes would come and go. The only time we got notification was when towing. Only 20 minutes after getting the first notification we were involved in an accident due to the trailer brakes not working. We thoroughly had the trailer brakes and plugs checked and they are not the problem .

The contact owns a 2022 GMC Sierra 3500 equipped with a 2024 Gatormade 35+5 Trailer. The contact stated that while driving on several occasions, the "Check Trailer Wiring" message was displayed. Additionally, when the brake pedal was depressed however, the trailer did not slow as intended; however, the rear brake lights were illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 40,000.

Encountering trailer brake issue where the brakes on our 5th wheel do not activate via the GMC Trailer Brake control module. Have just had it replaced and still experiencing the same issue where it posts an alert on the screen multiple times and does not activate brakes on trailer. This is a widely known issue with GMC trucks and the trailer brake that has been outstanding for over 3 years now and is a safety issue as there doesn't appear to be a fix from any dealerships or GMC. GMC has not taking adequate accountability for this issue. I'm looking at putting together a class action lawsuit with several other customers having the same issue. We are fed up with the inaction and falsely advertised towing package as we are unable to safely tow anything with their trucks.

The contact owns a 2022 GMC Sierra 3500. The contact stated that the check engine warning light was illuminated intermittently. The contact stated while driving approximately 50-70 MPH, the check engine warning light illuminated. Additionally, the contact noticed that the vehicle was experiencing reduced power and performance. The vehicle was taken to the dealer, where the NOx sensor was replaced and a manual DPF regeneration was performed. The vehicle was repaired and remained at the dealer. The contact related the failure to GM Campaign Number: N212351211. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 68,000.

While driving the truck began switching between towing, normal, and off-road driving modes. Lights were flickering and various messages were being displayed on the dash cluster screen. After parking truck and shutting it off all of the lights were flickering and I was unable to start the truck. Charging the batteries did nothing nor was I able to jumpstart the truck with another diesel. After repairs for these issues, at some point the odometer reset and while likely not certain it reset to zero. GM has no way of knowing when it reset and how many miles were driven between leaving the dealership and the reset leaving me with a truck set to the best guess mileage. I am being told this was a software bug and having experienced another software bug when I had the recall to enable seat warmers where the keyfobs would not work in any way I have serious concerns about the quality and safety of the software on these trucks.

I purchased 2022 GMC Sierra HD last year. Due to Micro Chip shortages at the time GMC provided custo.ers a $50.00 credit and notice that they provide the chips ASAP and that it should be provided by December 2022. I like many others accepted the risk for not having parking assist sensors and other features for this period of time. I contacted GMC last month after speaking with my dealer and was told by GMC customer service that GMC has instead adopted an approach of providing Chips to new vehicles while they work on getting chips for those vehicles already sold. No where in the agreements that customers signed did it acknowledge that we would be prioritized by GMC in order for them to make new vehicle sales over the increased safety risks. I drive a GMC HD (3500) which has significant blind spots and Increased safety risks to pedestrians as a result of no warning detection systems during parking in lots and on streets. I would like to have this risk mitigated by having GMC honor the agreements and commitments to its customers by providing the Micro Chips required to fulfill these safety requirements ahead of new sales, so no injuries or loss of life are sustained as a result of this profit over safety stance that GMC has adopted. I would like the NHTSA to assist consumers in addressing this safety issue.

Bought. New 2022 GMC HD 3500 last year and signed form from GMC saying front and rear parking sensors were delayed until December 2023, related to supply chain issues. I have continually tried to get a status of the needed micro chips and now have been told today that GMC has no status as they are focusing on the new vehicles so they can continue to sell vehicles and make profits. GMC knows this is an on going safety issue but continues to ignore vehicles already sold.

On July 27, 2022 I was driving my 2022 GMC truck on the freeway. I was rear ended by a semi truck and the passenger side was side swiped by the semi. I was driving the truck with my wife and two kids as passengers. The truck was completely totaled. No airbags deployed and the seat belts did not restrain us. All 4 of us were wearing seat belts. Also, the drivers seat completely broke, it looked like it had been completely reclined to a laying position. A police report was made. All 4 of us were taken by ambulance to the hospital. All 4 of us needed medical care. The truck was totaled and towed, the insurance has since taken possession of the truck. There were no warning lights, service lights or any indication that there was anything faulty with the truck. We had just purchased it in February 2022. My safety, as well as the safety of others was put at risk. The semi truck driver stated he was driving 60mph. If this isn't enough for air bags to deploy, I don't know what is. The seat belts also failed to restrain us. The seat belts were completely loose and during the accident failed to secure us. Again, the drivers entire seat completely broke causing severe head, neck and back injuries.
