Sunday 3/23 I was driving west on 225 heading towards work, all of a sudden the check engine light comes on and all kinds of other lights on the dash came on. I got pulled over and looked in the rear view mirror I seen flames. Quickly grabbed my stuff and got out of the car. The investigation at the time stated most of the heat was coming from the engine

The driver was sitting a red light when flames started emerging from the hood. The driver exited the car before the entire front of the car was engulfed in flames and ultimately destroyed. It is unclear what caused the fire but it might have been a wiring harness (or at least there was a wiring harness in the front drivers area under the hood). The car is available for inspection upon request. The safety of the drivers was at risk; he was lucky to be at a red light although he was forced to exit in the middle of a busy street. There is no problem to be reproduced but the incident was reported to Mercedes. The vehicle has not been inspected but the police and fire departments were on scene. There was no prior warning via lamps or other symptoms.
