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.
