2022 GMC SIERRA 2500 Electrical System Problems

Odometer Fraud. The contact purchased a 2022 GMC Sierra 2500. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 92,000, and at the time of registration, it was discovered that the mileage was 98,325. The Carfax report was not available at the time of purchase. The mileage discrepancy was later identified through the vehicle manufacturer’s Mobile App.

Mileage: 98,325

After driving my truck, once I park and turn the truck off it will not shut down electronically due to an error on the dash display that reads “shift to park”. Sometimes I have to mess with the gear shifter when the truck is in park to get it to register that it is parked and shut down completely. It can take up to 15 minutes sometimes to shut down.

After placing the vehicle in park and try to turn it off, I receive a message saying “Shift to Park”. The engine is off and in park, but the vehicle doesn’t recognize it as being in park so all of the electrical stays on. I started complaining about this to the dealerships before my warranty was up but they kept giving me the run around avoiding the fix and now that the warranty is expired they want to help me for a ridiculous fee. This issue happens randomly at least one day a week.

I was driving my 2022 GMC 2500 HD (not towing, just normal drive) after an oil change <900 miles ago and new brakes/rotors 3 days prior <100 miles (total mileage 81,000, serviced exclusively at GMC dealership) when the loss of power alert flashed on the screen. I was 2 miles from my destination, going approx 55mph, so I kept driving to destination, when the vehicle stalled in driveway. As I was scrolling through menus to see the alert I looked up and smoke and flames were coming out of the engine. I attempted to extinguish with a fire extinguisher I had with me, but it was no use. The entire engine was engulfed, melting out, tires and windshield exploded from heat etc. Total loss. Vehicle was inspected by insurance co fire investigator, no origin confirmed due to extent of damage. Vehicle was offered to GMC for their inspection as it was partially under OEM warranty and I had an extended warranty from dealership, which I also notified. Extended would not do anything without the vehicle at GMC and diagnosis, which again, there is no engine etc so not repairable. GMC was to be in contact with insurance co. No status update received.

The contact owns a 2022 GMC Sierra 2500. The contact stated while her husband was driving approximately 75-80 MPH, and the contact was in the front passenger's side seat, the vehicle lost motive power, and the infotainment system and instrument panel turned off unexpectedly. 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. The manufacturer advised the contact to take the vehicle to the dealer while the failure was occurring; however, the contact stated that the failure was occurring intermittently. The vehicle was not diagnosed or repaired. The failure mileage was approximately 4,000.

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.

[XXX]: After arriving home and parking in my driveway (plugged in the block heater that came installed from the factory), approximately 35 minutes later my neighbor rang the doorbell. She was yelling that my truck was on fire! The flames were starting to hit my eaves on my house. I put the fire out with my hose. The Sparks Fire Department had to pry open my hood to disconnect the batteries in order to stop the truck from lighting back on fire. The vehicle has been inspected by General Motors and turned over to their insurance. My insurance has also inspected the vehicle and stated they believe that the wiring to the block heater was faulty. There were no warning lamps, messages or other symptoms of the problem. This truck has 19,000 miles and is 1.5 years old (2022). How could this be turned over to GM's insurance and not under warranty? I have not had my truck for over 2 months now. I wonder how many of these trucks are lighting on fire? The truck is currently at the local dealership and is available for inspection.
