4 safety recalls for the 1981 Mack MS300T

Most recent first. Recall repairs are free at any authorised dealer. Click a recall for the full defect, consequence and remedy text.

  1. Manual transmission (power train)

    NHTSA 83V102000 Reported 565 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The yoke of the transmission propeller shaft may lack required strength due to erroneous counterbore operation in which 10 millimeters of extra material may have been cut. This condition could lead to fracture of the yoke in service.

    Remedy: All affected parts will be inspected and replaced, if necessary.

  2. Headlights (exterior lighting)

    NHTSA 82V054000 Reported 5,700 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The circuit wiring on these vehicles is arranged so that a short circuit in the rear taillights will also result in loss of power to the headlamps. For safety reasons the lighting system wiring should be independent.

    Remedy: Vehicles will have an automatic reset circuit breaker installed to ensure continued headlamp illumination in the event of a short in other lighting systems.

  3. Driveline (power train)

    NHTSA 81V089000 Reported 500 vehicles potentially affected MACK TRUCKS, INCORPORATED

    Holes drilled in the rear axle yokes to balance them could cause a failure of the yoke.

    Remedy: Vehicles will be inspected and all defective yokes will be replaced with yokes without holes.

  4. Switch (exterior lighting)

    NHTSA 81V032000 Reported 150 vehicles potentially affected MACK TRUCKS, INCORPORATED

    On certain vehicles, the semi-trailer stop lights may not activate when hand control lever is activated.

    Remedy: After inspecting brake light system, a switch will be installed which will activate the trailer stop light when the hand control valve is used, if necessary.

Checking a specific 1981 Mack MS300T

How do I know if my 1981 Mack MS300T 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. 4 campaigns currently list the 1981 Mack MS300T; 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 81V032000).

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.

Source: NHTSA recall and complaint databases and EPA fuel economy data, October 2026. Complaint counts are owner reports to NHTSA, not verified defects. Recall counts are safety campaigns that list this model year; whether a particular car was already repaired depends on its VIN. How this data is compiled.
