  1. Caliper (service brakes)

    NHTSA 80V073000 Reported 350,000 vehicles potentially affected CHRYSLER CORPORATION

    Due to a combination of disc brake pad wear and turn stop wear on certain vehicles, there may be an increase in brake pedal travel and a reduction in front braking effectiveness following a full turn. Also, a frame crack could develop and could extend through all or most of the rail section.

    Remedy: Upon inspection dealer will replace either the left or right turn stop bracket to correct the front brakes. If frame is cracked it will be welded and a rod reinforcement will be installed over the cracked area.

    Model years: 1973, 1974, 1975, 1976, 1977

  2. Air conditioner (equipment)

    NHTSA 79V176000 Reported 68,000 vehicles potentially affected CHRYSLER CORPORATION

    Condensate water may accumulate in the air conditioning blower housing; there is a high probability that this water will cause the blower motor to fail. Blower motor failure would disable the air condtioning unit and there would be no way to defrost or defog the windshield.

    Remedy: Dealer will drill a 1/4 inch drain hole in the bottom of the air conditioning blower housing to prevent water accumulation, without charge to owner.

    Model years: 1979

  3. Hoses, lines/piping, and fittings (service brakes)

    NHTSA 79V105000 Reported 50,000 vehicles potentially affected CHRYSLER CORPORATION

    The front brake hose routing may allow interference between the hoses and the tire and wheel assemblies during extreme turning angles.

    Remedy: Dealer will replace both left and right front brake hoses and install a new brake hose support bracket to eliminate contact with tire/wheel.

    Model years: 1978

  4. Suspension: lower arm

    NHTSA 79V104000 Reported 27,000 vehicles potentially affected CHRYSLER CORPORATION

    Lower control arms may fracture in the area adjacent to the lower ball joint, resulting in separation of the ball joint from the arm.

    Remedy: Dealer will increase the strength of both lower control arms by installing welded reinforcements.

    Model years: 1979
