FIRE FIRE FIRE Information light came on just saying 12 Volt Battery. I sat in the car letting it idle for about 3 minutes. It began to smoke and then burst into flames. I called 911 got the fire department here but by the time they were here there was not much left. The car essentially burned to the ground and insurance has declared it a total loss. Car was in my driveway, was certainly a danger to me, to my house and to my neighbor's cars and house.
