Transport Canada recalls

  • Brakes#2025031

    4 units affected

    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.

  • Brakes#2024632

    6,855 units affected

    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.

  • Brakes#2021744

    2,624 units affected

    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.

  • Lights And Instruments#2020503

    146 units affected

    Issue: Certain trucks do not have the correct warning indicator to show when there is low air pressure in the brake system. Canadian regulations require the use of a symbol, instead of text, for the low air pressure warning. This can help to avoid driver confusion. Safety Risk: This small error does not affect the function of the air brake system or the accuracy of the information displayed. Corrective Actions: This is not a recall. Mack has made changes to ensure that all new vehicles display the correct symbol when there is low air pressure in the brake system.

  • Lights And Instruments#2019638

    222 units affected

    Issue: On certain trucks, the headlights may not be aimed correctly. Safety Risk: Headlights that are not properly aimed could cause reduced visibility as well as glare for oncoming drivers and increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and instruct you to take your truck to a dealer to inspect the headlights. The headlights will be adjusted as necessary.
