My Rav4 caught fire in the middle of the night while parked on the street in front of my house. It had been parked for 12+ hours. After burning for about 10 minutes, it exploded with a force so great that it lifted the car onto the curb, knocked over a firefighter, and damaged our boat parked 10 feet across the street. The inspector from the fire department determined the initial fire was from faulty electrical wiring but said he had never seen a car explode in his 25 years on the force. Toyota conducted their own investigation and agreed it was electrical but could not determine fault due to the severity of the damage.
