I was driving on the highway and the engine shut off but everything else remained on. I drifted to the breakdown lane and turned the car off. It would not start again and the car began acting up by turning lights on and off, telling me to check the tire pressure, and not unlocking the doors. I then saw some very light smoke from the engine compartment. I popped the hood and looked and saw a glow on the bottom side of the engine area. Then the car just went up in flames.
