Transport Canada recalls
05- Powertrain#2026108
103 units affected
Issue: 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. Safety Risk: Sudden and unexpected movement of the truck could increase the risk of an injury or a crash. Corrective Actions: 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.
- 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.
- Steering#2023708
21 units affected
Issue: 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. Safety Risk: A loss of steering control could create the risk of a crash. Corrective Actions: 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, if necessary, replace it.
- Electrical#2023630
70 units affected
Issue: On certain trucks, the engine may not return to idle if the accelerator pedal position sensor becomes disconnected. As a result, the trucks don't meet certain requirements of Canadian regulations. Safety Risk: An engine that doesn't return to idle could cause a loss of control and increase the risk of a crash. Corrective Actions: Mack will notify owners by mail. The corrective actions for this recall are under development.
- Engine#2023588
10 units affected
Issue: On a small number of trucks equipped with a Cummins L9N natural gas engine, when the engine is lifted, the rear lifting bracket attached to the cylinder head could detach. If this happens, the engine could swing or fall. Safety Risk: An engine that swings or falls could create a risk of injury. Corrective Actions: Cummins will notify owners by mail and advise you to take your truck to a Cummins authorized service center to inspect and, if necessary, replace the studs on the rear lifting bracket.
