Switch to another Mack Md model year.
Safety recall notices and repair campaigns registered for the 2022 Mack Md in Canada.
On certain trucks, the passenger-side seat belt anchor may not have been secured to the floor properly. As a result, the seat belt could detach in a crash. Note: For the MD model, this recall also affects certain 2025 model year MD electric vehicles.
A seat belt that detaches could increase the risk of injury in a crash.
Mack will notify owners by mail and advise you to take your truck to a dealership to reinforce the passenger-side seat belt anchor.
On certain trucks, the tail lamps do not turn on when the daytime running lamps (DRLs) are on. New Canadian regulations require that, if a vehicle has dash backlighting, the low beam headlamps and tail lamps must automatically switch on when it is dark or the tail lamps must stay on at all times.
Driving without tail lamps in low light conditions could make the truck less visible and increase the risk of a crash.
Mack will notify owners by mail and instruct you to take your truck to a dealer to update the vehicle software.
