This just happened to a friend of mine! His 2020 Silverado - parked at his house - started on fire. Burned out the entire cab. GM telling him and the dealership they won’t do anything. Truck is 6 months old for goodness sake! There us clearly a serious risk of fire. You’d think gm would want to check it out to see if it’s a design flaw or an isolated incident. Thank god no one was hurt and the truck was parked outside in the driveway!
