The contact's husband pressed the PUSH to START button, and the vehicle was able to be restarted. There was no warning light illuminated. The contact stated that while driving 70-75 MPH on one occasion, the vehicle shut off unintendedly. The contact exited the highway and pulled into a gas station. The contact stated that upon pressing the PUSH to START button, the vehicle restarted as needed. The contact stated that the failure recurred while driving on a third occasion; however, the vehicle was able to restart independently. The vehicle was taken to the dealer several times, but the dealer informed the contact that the failure could not be duplicated. The contact stated that the failure recurred. The vehicle was taken back to the dealer, where the battery was replaced; however, the failure persisted. The manufacturer was notified of the failure and informed the contact that no assistance could be provided because the vehicle was not covered under warranty.

After taking my truck in for recall fixes. I received a message on my screen saying that I had 94 miles until I was limited to 65 mph. It said check DEF system. After taking it in the dealership charged me to fix the computer. Known defect yet they charge for it.

The gmc trailering app will not read trailer tire pressure above 100psi. When trailer tires carry a safe psi amount above 100psi the trailering app will not be able to confirm if the trailer tire is low in pressure which could cause a massive wreck if driver did not know the trailer tire was going bad. Truck was taken to dealer, they tried to follow bulletin 22-NA-172 to have the pressure to read above 100psi. But they could not get it to work, I was told it was a trailering app issue and nothing they can do until GM takes the steps to fix the trailering app.

Trailering a trailer with electric brakes. The vehicle intermittently reports connection issues where the brakes are temporarily disabled however the trailer lights are not effected. This leads to a period of time where there are no brakes on the trailer. Pretty confident we have eliminated the trailer as causing the issue.

The vehicle will be in the park position and a warning on the dash will say shift to park not allowing you to shut off the vehicle. Jiggling the shifter sometimes works but often have to restart the vehicle numerous times to get the error message to not appear and be able to proceed with shutting off the vehicle

Concerning Goodyear Wrangler Trailrunner AT P275/65/20 tires that came stock with my 2022 GMC Sierra 2500HD, which currently has 42,000 miles on it. While driving a round trip of no more than 30 miles the evening of 11/29/24, I noticed a slight repetative jaring motion, which I initially attributed to a potential transmission issue. The bump rapidly worsened halfway though the drive. Upon inspection at the time, I could not see any visible damage to the tire. However, the issue escalated aggressively during my return home, resulting in the tire blowing out and detreading entirely. This failure caused significant damage to the body of my truck, amounting to an estimated $3,500 in repair costs. I believe this incident is due to a defect in the tire, as such occurrences are highly uncommon and unexpected from a product of your reputation. I have oil changes as recommended by the trucks service maunual and with ample tread left on the tire and good scores of inspection it begs the question on how a tire could fail so abruptly. I have 3 other tires with ample tread which should last at least another 10k miles but I'm gravely concerned with continued use of them for fear another blowout could cause a fatal accident.

The contact owns a 2022 GMC Sierra 2500. The contact stated that while driving approximately 65 MPH, the warning message "transmission overheated" had suddenly displayed and an audible alarm activated. The vehicle was later towed to the local dealer who diagnosed that the transmission valve body assembly needed to be replaced. The transmission valve body assembly was replaced and the failure was remedied. The manufacturer was notified of the failure. The failure mileage was 18,334.

AC will not run while truck is in idle. I was told by the dealer all GM trucks with the 6.6 gasoline engine this is a standard on them. this is a major safety issue when it becomes 100 F outside.

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.
