About five million car and truck owners haven't responded to notices that warn of a potential fire hazard in Ford factory installed cruise control systems. Blazes can occur whether or not the vehicle is running, and some house fires have begun when a parked car or truck caught fire while it sat in a garage or close to the home. More cars and trucks have been added to the list of affected vehicles since this recall went public in 2005. My truck is included. Is yours?
