I was stopped at a red light at an intersection, when a car pulled up next to me, and the driver rolled down the window to tell me my vehicle was on fire. I got out of my vehicle while the driver of the other car called 911. Brookline Police & Fire came, firefighters extinguished the fire, and one of the emergency services responders had a wrecker come & take the car away. The car was towed to Watertown, then collected by Safety Insurance, which got a repair estimate of $95,000. The car was deemed a total loss and is in the possession of the insurance company. When the vehicle caught on fire, it had 3,627.4 miles on it. I did not see any warning lamps, messages or other symptoms of the problem prior to the fire. My safety and the safety of others was at risk due to the sudden and unexplained fire.
