NHTSA said there is interference between the positive battery cable and the electronic control module to the engine on certain trucks. Chafing can wear through the battery cable insulation, allowing contact between the battery cable and the stud. This contact could cause a short circuit, which may result in a fire.
Officials from Western Star Trucks' parent company,LLC, said dealers will inspect the vehicles, and the battery cables will be replaced or re-routed as necessary. Owner notification will begin this month.
