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.
International Motors will notify owners by mail and advise you to take your truck to a dealership to reprogram the ECU software.
On certain vehicles, the warning light for the antilock brake system (ABS) doesn't stay on when there's a problem with the system, and the vehicle is moving.
A driver that is not warned about a problem with the antilock brake system could have an increased risk of a crash.
Navistar will notify owners by mail and instruct you to take your vehicle to a dealership to update the brake system electronic control unit software.
On certain trucks, the backup lamps could be blocked and may not be visible. As a result, the trucks don't meet the requirements of the Canadian regulations. Note: This recall only affects trucks equipped with a pintle hook lowering bracket and feature code 01WPN, 01 WPS, or 01VAL.
Backup lamps that aren't visible could cause a person not to recognize that the vehicle is backing and increase the risk of a crash.
Navistar will notify owners by mail and instruct you to take your truck to a dealership to install new tail stop/turn signal lamps with integrated backup lamps.
On certain trucks, the connecting rod bushings could fail due to a manufacturing defect. This could cause an engine failure that can result in a sudden loss of power with an inability to restart. Note: This is an expansion of recall 21505 (Transport Canada Recall 2021-240).
A sudden loss of engine power could increase the risk of a crash. Additionally, a stalled vehicle could also increase the risk of crash.
Navistar will notify owners by mail and instruct you to take your truck to a dealer install a detection system to warn a driver if there is a problem with the connecting rod bushing. The system will cause a red engine warning light to turn on if a problem is detected, before a connecting rod failure happens. Engines found with a suspect connecting rod will be repaired.
On certain trucks, the battery ground cables that connect to the vehicle frame could overheat. If this happens, the battery post could separate and cause a loss of electrical power. As a result, the engine could shut off suddenly.
Overheated battery ground cables could create a burn risk. A loss of power while driving could increase the risk of a crash.
Navistar will notify owners by mail and instruct you to take your truck to a dealership to replace the alternator positive and ground cables. The dealer will also reroute the alternator ground connection from the frame rail to the starter.
On certain trucks, the connecting rod bushings could fail due to a manufacturing defect. This could cause an engine failure that can result in a sudden loss of power with an inability to restart. Note: This replaces recall 20504 (Transport Canada recall 2020-198). Trucks that previously had new connecting rods installed or that have the latest engine software update do not require this repair.
A sudden loss of engine power could increase the risk of a crash. Additionally, a stalled vehicle could also increase the risk of crash.
Navistar will notify owners by mail and instruct you to take your truck to a dealer install a detection system to warn a driver if there is a problem with the connecting rod bushing.

On certain trucks, the spring brake chambers may have been built with defective springs. Over time, this could cause wear and result in an air leak that can cause the parking brake to apply suddenly.
A parking brake that self-applies while driving could increase the risk of a crash.
Navistar will notify owners by mail and instruct you to take your truck to a dealer to inspect the spring brake chambers. Any chamber with a shifted pressure plate will be replaced.
On a small number of trucks, 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.
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.
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.
On certain trucks, the ring terminal that attaches the battery ground cable to the frame may break. If this happens, there could be a loss of electrical power and the engine could shut off suddenly.
