20250312025-01-24. Brakes. Issue: A small number of trucks may have been manufactured without the wiring for the antilock braking system (ABS) for a towed trailer. Additionally, there is no warning light to advise the driver if the ABS for the trailer isn't working. Safety Risk: An antilock braking system that doesn't work could increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and advise you to take your truck to a dealership to install the ABS wiring and warning light.
20246322024-10-24. Brakes. Issue: On certain trucks, poor signal strength could cause the electronic control unit (ECU) to stop working or not to work properly. As a result, some safety systems may not work, including the antilock braking system, automatic traction control, electronic stability control, active cruise control and the collision mitigation system. Safety Risks: Vehicle safety systems that don't work correctly could increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and advise you to take your truck to a dealership to reprogram the ECU software.
20217442021-12-09. Brakes. Issue: On certain trucks, the parking brake control valve may wear and leak. In certain situations, this could cause the parking brake to release suddenly and the truck could roll away. Safety Risk: A parked vehicle that moves suddenly could increase the risk of an injury or a crash. Corrective Actions: Mack will notify owners by mail and instruct you to take your truck to a dealer to remove the exhaust tube and fitting from the parking brake control valve.

A campaign lists a year, a make and a model, and often only some of the vehicles built. A list with nothing on it is not a clearance either. The lookups below check one VIN.
