Within minutes, the front end was bursting in flames. The fire destroyed the entire front portion of the car, including the engine, transmission, tires, and dashboard. I don't know what could have been the cause; it was seemingly random.”

They suggested a plastic bag or similar object blew up from the roadway setting the vehicle components on fire. Another suggestion was that a service person left something in the engine compartment. …”
