On Christmas Day 2025 my Tailgate flies open on its own and I see my cargo flying out and a piece of it bounced off my taillight passenger side braking the taillight and then when attempting to pull over my lane departing feature try’s to correct its self and I hit the median luckily at slower than I was going but enough to make a decent dent on front bumper

The brake controller on trucks error out while towing. Shuts brakes off. Not a good thing towing 16,000lbs down hill. Almost accident. Destroyed my truck brakes and warped rotors. The controller checks the house battery on trailer and if not in range shuts brakes off. The brake towing screen in truck states all is good but there is this tiny little light at gain adjust location that goes off and you do not have brakes but yet your screen states you do. Bad deal.

My truck has the shift to park issue and won’t allow me to shut the vehicle ignition off and I cannot shut the vehicle ignition off and it is unsafe and keeps me trapped in my vehicle. I have noticed that it is a common issue and recall on many gmc trucks and I took it to the dealership and they are not wanting to cover it with my two warranties I have on the truck and my vehicle is unsafe. I cannot park the vehicle and shut it off. When I go to put the truck in park on shift column lever, it says shift to park on dash and I turn it on and move shifter to drive and neutral and the vehicle still won’t allow me to shut it off and it shows the same issue.. the issue just began out of no where.

275/65R20 - Goodyear Wrangler. This is the tire that came with the vehicle. It had approximately 32,000 miles. The tire separated and exploded. We installed the spare but one of the other tires is getting ready to explode. This is not normal wear and tear. This is out of the ordinary that tires on a new vehicle explode. We were on [XXX] when this happened. This tire is a death trap. This is forcing us to replace all 4 tires because we do not know what is going to happen. The dealership (Jerry Seiner) will do NOTHING. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 GMC Sierra 3500. The contact stated while driving at various speeds and hauling a 2023 Merhow Horse trailer, the TPMS became inoperable and could not read the trailer tire pressure. The vehicle was taken to the dealer, where it was diagnosed and determined that the failure occurred due to the TPMS sensor location and range. The dealer informed the contact that the TMPS sensor was losing the WI-FI connection because it was located behind the license plate, and the TMPS sensor was designed with a 23-ft. range. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 7,000.

CRITICAL PART FAILURE - The master cylinder attached to the brake pad is leaking at the seal where the piston is depressed into the cylinder. It's leaking brake fluid onto the driver brake assembly and some sort of cable. While this is repairable under warranty, this should NEVER ever happen on a vehicle. Arguably, the main part on the most critical system on the car - the brakes. Please investigate whether GM should be responsible for replacing this part on any affected vehicle for the life of the vehicle Thank you for all you do to keep us safe! Have a great day

The vehicle experienced a catastrophic fuel system failure involving the high-pressure fuel pump and related fuel system components. While driving, the engine began stalling and lost power, making the vehicle unsafe to operate. The failed components were replaced during repairs; however, the repair records, photographs, and additional documentation are available for inspection upon request. The failure created a significant safety risk because the vehicle stalled unexpectedly while being driven, resulting in a sudden loss of power. This placed the occupants and surrounding motorists at risk by reducing the driver's ability to safely control the vehicle or move it out of traffic. The problem was confirmed by an independent repair facility, which documented extensive metallic contamination (metal shavings) throughout the fuel system. Photographs and videos taken during the inspections document metallic contamination within the fuel system. From our understanding, cp4 pump failure has been a common issue.

I was driving in the high way and the vehicle started having issues and then it completely shut off and wouldn’t drive or anything in the middle of the highway and the dash said it was reducing power.

I was in an accident and was hit in the right front side of my truck. The other vehicle was believed to be going around 50 mph and I had just rolled thru a stop sign. The other vehicle that hit me had the air bags deploy, but my airbags did not deploy. This is very concerning considering there was enough force to significantly bend the frame on my truck. I was transported to the ER and suffered internal organ bruising due to the accident. If the airbags would have deployed, my body could.have not jolted so much causing these injuries.
