79V117000 · Service Brakes, Hydraulic:pedals And Linkages

May 15, 1979

THE INVOLVED VEHICLES WERE PRODUCED WITH BRAKE PUSH-ROD TO BRAKE PEDAL RETAINING PINS WHICH WERE NOT HEAT-TREATED AS SPECIFIED. THIS COULD ALLOW THE BRAKE PEDAL TO BECOME DISENGAGED FROM THE PUSH-ROD.

Consequence & remedy

Consequence: Not supplied

Remedy: DEALER WILL REPLACE THE SUSPECT BRAKE RETAINING PIN.

79V106000 · Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings

Apr 30, 1979

SOME OF THESE VEHICLES WERE PRODUCED WITH MISINDEXED FRONT BRAKE HOSES WHICH COULD CONTACT A TIRE OR WHEEL IN A FULL-TURN CONDITION. CHAFING AND WEAR TO THE BRAKE HOSE COULD RESULT IN LOSS OF BRAKE FLUID AND FRONT WHEEL BRAKING CAPABILITY.

Consequence & remedy

Consequence: Not supplied

Remedy: DEALER WILL INSPECT AND, IF NECESSARY, RE-INDEX THE FRONT BRAKE HOSE. THOSE HOSES SHOWING SIGNS OF ABRASION WILL BE REPLACED, WITHOUT CHARGE TO OWNER.

78V212000 · Steering: Steering Wheel/handle Bar

Oct 4, 1978

THE LOWER STEERING SHAFT ASSEMBLIES CONTAIN COUPLING RIVET PINS WHICH WERE NOT RIVETED SECURELY ENOUGH DURING MANUFACTURE. CONSEQUENTLY ONE OR BOTH OF THE PINS COULD LOOSEN FROM THE FLANGE OF THE FLEXIBLE COUPLING DURING VEHICLE OPERATION. IF ONE PIN IS LOOSE, FREE PLAY WOULD RESULT. IF BOTH PINS WORK LOOSE, LOSS OF STEERING CONTROL WOULD OCCUR. ALSO, THE SHAFT ASSEMBLY MAY NOT CONTAIN A METAL REINFORCEMENT BETWEEN ONE OR BOTH OF THE RIVET PINS AND THE RUBBER FLEXIBLE COUPLING. AS A RESULT, THE RUBBER FLEXIBLE COUPLING COULD TEAR AND PRODUCE A NOISE OR LOOSE FEELING IN THE STEERING SYSTEM.

Consequence & remedy

Consequence: Not supplied

Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE STEERING SHAFT ASSEMBLY, WITHOUT CHARGE TO OWNER.

78V198000 · Electrical System:wiring:fuses And Circuit Breakers

Sep 11, 1978

THE WINDSHIELD WIPER AND WASHER SYSTEM CONTAINS AN INCORRECT 6 AMP CIRCUIT BREAKER INSTEAD OF THE 8.25 AMP CIRCUIT BREAKER. IF THE SYSTEM IS HEAVILY LOADED, AS IN THE CASE OF A PARTIALLY DRY WINDSHIELD, THE MOTOR CURRENT MAY EXCEED THE 6 AMP BREAKER"S CAPACITY. THIS WOULD CAUSE THE BREAKER TO OPEN, WHICH WOULD RESULT IN WIPER/WASHER FAILURE.

Consequence & remedy

Consequence: Not supplied

Remedy: DEALER WILL INSTALL THE CORRECT CIRCUIT BREAKER WITHOUT CHARGE TO OWNER.
