The car had not been driven and was only in use for about 20 minutes. Then, the check engine light came on. I was planning to take the next exit to investigate. About a minute after the check engine light came on, several other lights came on. They stopped about 20 seconds later. The car began to smoke and as I was pulling over, smoke began to enter the cab. When I pulled over, the car began was on fire. Highway patrol and Cal Fire arrived. Cal Fire put the fire out. It was a total loss. Highway 101 was shut down for a bit while the truck was on fire.
