  1. Steering wheel/handle bar (steering)

    NHTSA 79V134000 Reported 64,150 vehicles potentially affected MACK TRUCKS, INCORPORATED

    In the involved trucks it is possible the adjustable steering column rear mounting bracket could fail, allowing steering wheel assembly to fall down onto the operator"s lap.

    Remedy: Dealer will install an additional bracket in this area to prevent the steering wheel from dislocating in the event of a bracket failure.

  2. Service brakes, air: control unit/module

    NHTSA 78V068000 Reported 9,700 vehicles potentially affected MACK TRUCKS, INCORPORATED

    An axle "no brake" condition could result from an eaton controller internal electrical malfunction. This condition may cause the anti-wheel lock valve solenoid to be continuously energized and prevent the brakes from being applied on one of the axles. As a result, the anti-wheel lock warning lamp is not activated.

    Remedy: The dealer will inspect and, if necessary, replace the anti-wheel lock controller without charge to owner.

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

    NHTSA 78V030000 Reported 400 vehicles potentially affected MACK TRUCKS, INCORPORATED

    A design deficiency exists in the air dryer piping in the area of the pressure relief valve and compressor governor control link. Moisture is passed and builds up in this relief valve and control line. In freezing ambient temperatures, this moisture may freeze, allowing the chassis air system pressure to exceed 150 PSI. Excessive air…

    Remedy: The dealer will relocate the air system compressor governor line and pressure relief valve to eliminate moisture accumulation.

  4. Fan (engine and engine cooling)

    NHTSA 77V173000 Reported 48,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The flex blade fans on the involved vehicles may develop cracks in the laminated stiffener as a result of fatigue during operation. If such a condition exists and the cracks go undetected, continued operation could cause pieces of the stiffener to break off.

    Remedy: Dealer will replace the original fan with a steel fixed blade fan, free of charge.

Checking a specific 1975 Mack RL

How do I know if my 1975 Mack RL has an open recall?

Enter your 17-character VIN above. The VIN is on the driver's side dashboard (visible through the windshield), the driver's door jamb sticker, and your registration or insurance card. The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 8 campaigns currently list the 1975 Mack RL; your car may already have been repaired under some of them.

Is the recall repair free?

Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised Mack dealer with your VIN and the NHTSA campaign number (for example 75V070000).

What is the difference between a recall and a complaint?

A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
