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 with the main battery. No smoke, fuel odor, intentional ignition source, charging device, or known external fire source was present before the incident. Weather was calm. The exact failed component and cause remain UNKNOWN. A firefighter stated that the apparent fire origin was near the passenger side of the vehicle. The remains are available for inspection, subject to coordination with the vehicle owner and insurer. The incident has been reported to the fire department, insurer, manufacturer, and NHTSA.
