Transport Canada recalls

Brakes#2024121February 23, 2024
171 units affected
Issue: On certain trucks, the reservoir tank for the air brake system is too small. In certain situations, this could cause reduced braking. Canadian regulations require enough air reservoir capacity to ensure the brakes work even with heavy use or when there is a partial loss of the air system. Safety Risk: Reduced braking can cause extended stopping distances and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to replace or add an additional air reservoir tank, as necessary.
Seats And Restraints#2023573October 26, 2023
1,532 units affected
Issue: On certain trucks, a spacer installed between the seat frame and the seat belt buckle may cause the seat belt to slip and not to work properly in a crash. Safety Risk: A seat belt that doesn't work properly could increase the risk of injury in a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to remove the spacer(s) and replace the bolt(s).
Powertrain#2021069February 17, 2021
47 units affected
Issue: On certain vehicles, the cap screws that attach the flywheel to the crankshaft may not have been properly tightened. As a result, the flywheel could detach. If this happens, there could be a loss of power to the wheels and parts could be ejected from the engine compartment. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Parts that are ejected from the engine compartment could create a risk of injury. Corrective Actions: Cummins will notify owners by mail and instruct you to take your truck to a Cummins authorized service center to tighten the flywheel cap screws. Cummins will repair damaged components, as necessary.
Suspension#2020399August 27, 2020

Issue: On certain trucks, the lift axle pivot bolts may be too short and may not be properly tightened. As a result, the bolts could come loose or break. If this happens, parts could fall from the truck. Note: This recall only affects trucks built with Watson Chalin SL2065 lift axles. Safety Risk: Large fasteners that fall on the road could create a road hazard for others and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to inspect and replace the lift axle pivot bolts, as necessary.

Risk: Insufficient air volume can reduce braking performance and increase the risk of a crash.
Remedy: Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025.
