My car had been sitting across the street from my house for about 3 weeks after i had gotten it back from the body shop. It had been hit on the drivers side by a drunk driver when parked in front of my house. He took out six cars in a row. Heard a loud noise about 2 am - looked out the window and saw nothing. But then the fire trucks showed up after someone called them when they heard the bang. according to the firemen, it was probably caused by an electrical fire even though there were no visible flames. but the inside was filled with thick gray smoke which also came out of the trunk when they opened it. , the air bag was activated on the driver's side - the windshield was broken and the interior was a melted mess. The dashboard was melted on the driverâs side and the window was blackened. .the drivers side was where the damage had been from the accident. I do not think it coincidence. It seems i am not the only person whose bmw has spontaneously caught on fire. I did get bmw involved as far as sending documentation and talking to a rep. They of course were blameless. They did say they believe it was caused by an error made during a repair that allowed the rain water to get into the wiring. It had been raining hard for a couple days. But they could not say based on what i sent them if it was the body shop that did the most recent repair that made the error or it was done prior to that by another shop. But that they would not be investigating further.
