Mileage when the problem started
What owners report
A warning light illuminated as the driver was pulling into a bank parking lot. The vehicle was left running while the driver briefly stepped away to use the ATM. When he returned, he saw smoke coming out of the glove compartment. When the glovebox was opened, an active fire was already burning inside the dash cavity behind it. The fire grew rapidly and resulted in full cabin flashover, destroying the interior, melting wiring, and causing structural damage. The burn pattern clearly shows the fire originated inside the passenger-side dash/glovebox area, not the engine compartment. Photographs taken immediately after the incident show melted and fused copper wiring, arc beads, vaporized insulation, and connectors burned from the inside outward. Harness bundles were burned from the inside out, consistent with electrical arcing. …
