The Drivers side door (light at the bottom of the door) sparked and then the door went up in flames. At that point the electricity in the car ceased to work. The car is available for inspection at the dealership where we had it towed. If the door was closed and there was someone in the car when it happened then they would have gotten burned or worse. Our insurance company is investigating and Lexus has been taking their time and helpful in the matter. Fire Department checked out the car at the time and said the wires in the door were very hot after putting out the fire. There were no symptoms or warnings prior to this happening.
