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.
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, if necessary, replace it.
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.
An engine that doesn't return to idle could cause a loss of control and increase the risk of a crash.
Mack will notify owners by mail. The corrective actions for this recall are under development.
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.
An engine that swings or falls could create a risk of injury.
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.
