On certain vehicles, the speed control deactivation switch may overheat, smoke, or burn, potentially resulting in an underhood fire. The condition may occur either when the vehicle is parked or when it is in operation. Correction: Dealers will install a new switch or fused wiring harness. Note: This is an expansion of recall 2005028 (05S28) for vehicles not previously included in the campaign.
On certain vehicles equipped with a 7.3L diesel engine, the camshaft position sensor may fail, causing the engine to stall. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will inspect and, if required, replace the camshaft position sensor.
On certain vehicles, the speed control deactivation switch may overheat, smoke, or burn, potentially resulting in an underhood fire. The condition may occur either when the vehicle is parked or when it is in operation. Correction: Initially as an interim repair, owners will be instructed to return their vehicles to their dealers to have the speed control deactivation switch disconnected. As soon as replacement parts are available, owners will be instructed to return to the dealers for installation of a new switch or fused wiring harness.
Certain passenger cars, sport utility vehicles, and light and medium duty pickup trucks. A switch located in the plastic cover of the wiper motor gear case could malfunction and overheat, potentially resulting in loss of intermittent wiper function, loss of wiper park function, complete loss of wiper function, smoke or, potentially, ignition of the plastic cover material. Switch malfunction is most likely to occur when the intermittent setting of the wipers is being used, or when snow or ice obstructs the blades from returning to the "parked" position at the bottom of the windshield. Loss of visibility while driving increases the risk of a crash. Correction: Dealers will inspect the date code on the wiper motor. Motors built with the suspect time frame will have the wiper motor gear case cover replaced.
On certain vehicles, the headlamp switch knob may have been molded from a plastic material that is more brittle than the intended material. This material may be overstressed when the knob is installed on the switch, leading to a later fracture, and in some cases, separation of the knob from the headlamp switch. If this should occur, it may be difficult for the driver to activate the headlamps. Correction: Headlamp switch knob will be replaced with one made of the intended material.
