Wayne drove the truck to work. It was an icy day in Texas so he drove slower than usual. He went to pick up a part (for work) from another shop, he arrived at the shop, turned off the truck and went inside to retrieve the part for work. A few minutes later he came out to his truck and the hazard lights were blinking. He did not turn them on. He then noticed the cab of the truck filled with black smoke, he opened the door, raised the hood to take off the battery cables. The fire destroyed his dash and all electrical in the dash. There were no warnings or messages that appeared prior to the fire.
