Safety recall notices and repair campaigns registered for the 2022 Mack Terrapro in Canada.
On certain trucks, a software problem could allow the engine to be started with the transmission in the drive or reverse gear. If this happens, the truck could move suddenly when it is started.
Sudden and unexpected movement of the truck could increase the risk of an injury or a crash.
To reduce the safety risk, Mack recommends you ensure the transmission is in the neutral gear before starting the engine until the recall repairs have been completed. Mack will notify owners by mail and advise you to take your truck to a dealership to update the ECU software.
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.
An antilock braking system that doesn't work could increase the risk of a crash.
Mack will notify owners by mail and advise you to take your truck to a dealership to install the ABS wiring and warning light.
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.
Vehicle safety systems that don't work correctly could increase the risk of a crash.
Mack will notify owners by mail and advise you to take your truck to a dealership to reprogram the ECU software.
On certain trucks, the steering gear may not have been assembled correctly. As a result, the steering gear could break and cause a loss of steering.
A loss of steering control could create the risk of a crash.
Mack will notify owners by mail and instruct you to take your truck to a dealership to inspect the serial number on the steering gear, and replace it, if necessary.
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.
A parked vehicle that moves suddenly could increase the risk of an injury or a crash.
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.
