On certain vehicles, the electrical power cords of some dealer installed block heaters may have been improperly manufactured, causing the wires to contact each other, resulting in a short circuit. A short circuit could lead to a fire which would increase the risk of injury and/or damage to property. Correction: For vehicles where the subject block heater was approved for installation, the dealer will replace the block heater assembly with a new one of an improved design. For vehicles where the subject block heater was not approved for installation, dealers will remove the block heater assembly. In the interim, until the remedy can be performed, dealers will cut the plug end from the block heater cord to disable the block heater's operation.
