Vehicle was driven a mile to a commuter rail station for a drop off and back home. Nothing unusual was noted during the short trip nor had any problems been observed in the days leading up to the incident. Shortly after parking the vehicle on the 5th floor of the parking garage and entering the residence, the complex fire alarms actuated and all residents were advised to evacuate without entering the community parking garage. Shortly thereafter, I was notified by the complex manager via my cell phone that my car was on fire in the garage. The entire front of the vehicle was burned and was declared a total loss by the insurance company. (allstate). The entire car would have burned if it hadn't been parked directly under a sprinkler head in the garage plus a speedy response from the fire department. An independent fire origin investigator was hired by the insurance company. His professional opinion was the fire started at the radiator fan assembly.
