Transport Canada recalls
05- 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.
- Lights And Instruments#2022361
4,304 units affected
Issue: On certain trucks, some controls are not identified with the required symbol(s) or word(s). Specifically, the identifications for the HVAC fan control, the position side marker light control, the master lighting switch control and the turn signal control may be missing or mislabeled. Canadian regulations require the use of certain symbols and words for controls. This can help to avoid driver confusion. Safety Risk: These small errors do not affect safety or the function of the controls. Corrective Actions: This is not a recall. Mack has made changes to ensure that the controls for all new trucks are identified with the required symbol(s) and word(s).
- Lights And Instruments#2021124
4,883 units affected
Issue: On certain trucks, when the manual override is used to switch off the daytime running lamps (DRLs), the lights may not turn on again when you start driving. Canadian regulations require that if DRLs are manually turned off, they must turn on again when you start driving. Safety Risk: Driving without daytime running lights could make the vehicle less visible to others 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 update the vehicle software.
- Structure#2020551
91 units affected
Issue: On certain trucks, the welds that attach the trailer hitch may crack due to improper welding. As a result, the hitch could detach from the truck while towing a trailer. Note: This recall only affects certain trucks with trailer hitches installed by Commercial Truck Equipment. Safety Risk: A trailer that detaches from a truck could create a risk of a crash. Corrective Actions: Commercial Truck Equipment will notify owners by mail and instruct you to take your truck to a dealer to inspect the trailer hitch and repair or replace it, as necessary. You should stop using the trailer hitch until the inspection and repair have been completed.
- Visual System#2019037
761 units affected
Issue: On certain vehicles, the down-view mirror may detach from the passenger’s door. Safety Risk: A mirror that falls from the vehicle could strike another vehicle or pedestrian. This may create the risk of an injury or crash. Corrective Actions: The company will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to secure the mirror. The dealer will add additional fasteners and a reinforcement plate as needed.
