Vehicle was parked, engine off, and unattended. An internal electrical fire originated in the overhead/sunroof wiring area. Damage includes melted wiring harness near the sunroof, burned center console, and soot throughout the interior. The fire originated in a constant-power electrical circuit and spread downward into the cabin. There were no aftermarket modifications, no external heat sources, and no objects in the vehicle that could have caused ignition. Ambient temperature conditions were normal and insufficient to cause this damage. This represents a serious safety defect because the fire originated spontaneously within the vehicleâs electrical system and could have resulted in a full vehicle fire or injury if occupants were present. The failure appears to involve factory-installed wiring/components and is not consistent with normal wear or external factors.
