Every NHTSA safety campaign that lists a GMC C30, most recent first, with the model years each one covers.

  1. Switch (exterior lighting)

    NHTSA 79V142000 Reported 15,328 vehicles potentially affected GENERAL MOTORS CORP.

    On the involved vehicles the brake stoplight and cruise control switch which is operated by the brake pedal may have been assembled with an incorrect lubricant on the actuating plunger. This can cause the rear brake stoplights to become inoperative and the cruise control, if activated, to stay electrically engaged.

    Remedy: Dealer will inspect and, if necessary, replace the brake stoplight and cruise control switch at no cost to owner.

    Model years: 1979

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

    NHTSA 79V026000 Reported 222 vehicles potentially affected GENERAL MOTORS CORP.

    The front hoses on the involved vehicles may have improperly oriented hose fittings, resulting in a rubbing contact between the right brake hose and the upper control arm of the front suspension or in a twisted left hose resulting in a faulty attachment at the frame fitting. Should either of these conditions exist, they could eventually…

    Remedy: The dealer will inspect and, if necessary, replace one or both front brake hoses at no cost to owner.

    Model years: 1979

  3. Vacuum (service brakes)

    NHTSA 77V119000 Reported 1,232 vehicles potentially affected GENERAL MOTORS CORP.

    On the involved vehicles, the nuts which attach the brake master cylinder to the hydro-boost unit may have been over-tightened. This could have caused stripped threads and cracked attaching flanges. Should these nuts fail, the parts may separate and loss of service brakes would result.

    Remedy: Dealer will inspect for cracks in the attaching flanges; units with cracks present will be replaced. If no cracks are found, the studs will be removed and the holes drilled out. The unit will be reassembled using bolts…

    Model years: 1977

  4. Suspension: lower arm

    NHTSA 77V098000 Reported 107,584 vehicles potentially affected GENERAL MOTORS CORP.

    The front suspension control arms were assembled with ball joints which may contain sockets that were not properly heat-treated. This may cause the socket to wear rapidly and allow the ball joint stud to separate from the socket, causing either the left or right wheel suspension to collapse.

    Remedy: Dealer will inspect and, where necessary, will replace the ball joints without charge to owner.

    Model years: 1975

  5. Differential proportional valve (service brakes)

    NHTSA 75V214000 Reported 39,278 vehicles potentially affected GENERAL MOTORS CORP.

    Model years: 1976

  6. Multi piece (wheels)

    NHTSA 75V165000 Reported 1,441 vehicles potentially affected GENERAL MOTORS CORP.

    Model years: 1975
