On 07/10/2026 at approximately 1:10 a.m., the parked and unoccupied vehicle caught fire while turned off. The vehicle had not been driven for several hours. A neighbor was awakened by the horn/alarm and popping noises, observed fire near the passenger-side cab/engine area, and called 911. The fire rapidly spread throughout the cab, engine compartment, rocker-panel areas, wheel wells, and truck bed, creating an explosion hazard and threatening a nearby occupied residence and garage. The fire department extinguished the blaze, but the vehicle was completely destroyed. Before the fire, the vehicle had experienced recurring coolant warnings, a DEF-system warning, and delayed starting associated…

While merging into highway traffic the truck surged with RPM going to 5,000. Shortly after this event there was a grinding or rattling noise in the transmission bell housing along with unusual shifting behavior and a repeatble vibration + rotational noise between 50 and 60 MPH. The vehicle was brought to the dealer for inspection at least 4 times with claims they could not hear the obvious noise that did not go away. On the last drop off, I picked up the vehicle and the noise was gone but the shifting behavior and the constant vibration from the transmission still persists. The dealer said GMC would replace the transmission for approximately $10,000 but I would need to cover 50% of the…

When I let the engine idle with windows up and AC on the overcharged battery introduced the vaporized sulfuric acid into the cabin and rendered the interior deadly toxic.…
