Something under the hood caught on fire while I was driving with my son, and I pulled over. I was stopped at a red light when I first noticed smoke when I was looking in the rearview mirror. The gauges and lights never indicated anything was wrong, which I was looking at while the car was smoking and I was trying to find a place to pull over. There was smoke billowing up from the hood and all around and in the back of the van. By the time the fire department got the fire out, most of the front was melted. When pulling over the brakes were hardly responsive. The vehicle is at the wrecker and has not been inspected.
