  1. Back up lights (exterior lighting)

    NHTSA 95V130000 Reported 5,482 vehicles potentially affected GENERAL MOTORS CORP.

    These vehicles were assembled with a transmission reverse signal switch that could leak causing loss of electrical contact when the transmission is in reverse. This does not meet the requirements of FMVSS no. 108, "lamps, reflective devices, and associated equipment."

    Remedy: Dealers will replace the reverse signal pressure switch.

    Model years: 1995

  2. Seats

    NHTSA 95V027000 Reported 1,720 vehicles potentially affected GENERAL MOTORS CORP.

    The seats of these vehicles can have incomplete welded left side seat back frame extender arm welds. Vehicles with affected seats do not comply with FMVSS no. 207, "seating systems."

    Remedy: Dealers will inspect the left side seat back extender arms of the seats for missing welds. Welds should be on both sides of the seat back extender arm. If a weld is missing, the affected seat back frame assembly(ies)…

    Model years: 1995

  3. Gear box (other than rack and pinion) (steering)

    NHTSA 94V028000 Reported 9,673 vehicles potentially affected GENERAL MOTORS CORP.

    The intermediate steering shaft was assembled with loose or missing upper and lower pinch bolts which may cause separation of the shaft.

    Remedy: Dealers will properly torque loose pinch bolts and install pinch bolts where necessary.

    Model years: 1993

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

    NHTSA 89V208000 Reported 215 vehicles potentially affected GREAT DANE TRAILERS, INC.

    The front air brake hoses can contact the inner fender extensions.

    Remedy: Cut out a portion of inner fender extensions to prevent interference. Also, replace any damaged front brake hoses.

    Model years: 1985, 1986, 1987, 1988, 1989, 1990

  5. Hydraulic power assist system (steering)

    NHTSA 86V170000 Reported 9,038 vehicles potentially affected GENERAL MOTORS CORP.

    The power steering assist cylinder mounting bracket bolts may loosen due to paint on the bolt threads and the mounting bracket mating surface. Consequence of defect: this may result in looseness and erratic steering during full turns. With continued operation power cylinder could detach from the frame rail resulting in restricted…

    Remedy: Remove paint from mating surfaces of bracket and frame rail; replace power steering assist cylinder mounting bolts.

    Model years: 1985, 1986

  6. Fuel rail (fuel system)

    NHTSA 85V110000 Reported 1,008 vehicles potentially affected GENERAL MOTORS CORP.

    The fuel return hose between the switching valve and the fuel tank sending units may be incorrectly connected. Consequence of defect: fuel supplied by one tank is returned to the other tank which could overfill and leak. Fuel could ignite and cause a fire.

    Remedy: Reposition fuel return hoses and replace fuel vapor canister.

    Model years: 1985

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

    NHTSA 85V085000 Reported 624 vehicles potentially affected GENERAL MOTORS CORP.

    The front air brake hose may contact the inner fender on the left and/or right sides of some trucks. In some instances, the brake hose may rub through, resulting in a loss of air pressure upon brake application. Consequence of defect: brake hose may rub through causing air pressure loss when brakes are applied and reduced braking…

    Remedy: Install new brake chamber support brackets, brake line elbows, and air brake hoses, as necessary.

    Model years: 1983, 1984, 1985

  8. Check valve (service brakes)

    NHTSA 84V120000 Reported 3,948 vehicles potentially affected GENERAL MOTORS CORP.

    The dual air reservoirs of some trucks were equipped with carbon steel springs instead of stainless steel springs, as intended. The carbon steel spring is more susceptible to rusting than the stainless steel spring. This rusting could cause the check valve to fail, causing total loss of front and rear brakes.

    Remedy: The air tank will be inspected and, if necessary, the air valve will be replaced with one containing a stainless steel spring.
