My wife drove the truck to walmart to get a couple of items with her were my son in law and daughter. Once arriving there(approx. 3 mi) they noticed some smoke coming from under the hood. My son in law opened the hood to discover a fire, he then ran into walmart where an employee grabbed a fire extinguisher and put out the fire.
