    Vehicle Speed Control

    Defect, in the NHTSA record
    Fuel injection system reconfiguration to comply with engine emission standards cause higher engine vibration levels which lead to early wear and complete failure of the secondary throttle return mechanism.
    Consequence, in the NHTSA record
    In the event the primary throttle return fails, failure of the secondary throttle return system would not provide protection against loss of throttle control.
    Remedy, in the NHTSA record
    A new production secondary throttle return system configuration will be installed.

    Visibility / Windshield Wiper/Washer / Linkages

    Defect, in the NHTSA record
    A tolerance mismatch in the crank assembly of the bosch windshield wiper motor could cause instantaneous separation of the crank from the linkage assembly in the left hand control arm assembly; this would make the system inoperable.
    Consequence, in the NHTSA record
    Wiper failure during vehicle operation could reduce driver's ability to see the road, and creates a potential for an accident.
    Remedy, in the NHTSA record
    Replace left hand control arm linkage assembly.

    Shaft failure during vehicle operation would cause loss of steering control and a crash without prior warning.
    Remedy, in the NHTSA record
    Enlarge frame rail through hole to prevent interference: replace steering gear sector shaft if scored.
