18027 - Customer Satisfaction Program. Certain vehicles may have been built with a connector between the electric power steering motor and torque sensor that has a potential for fretting corrosion. If this condition exists, power steering may be lost, and the driver may experience unanticipated increased steering effort as the vehicle reverts to manual steering. A chime will also sound in the vehicle, and a ?Service Power Steering? message will appear on the Driver Information Center (DIC). Manual steering functionality will be maintained but will require additional effort, particularly at lower speeds. Dealers are to replace the complete power steering rack assembly.
