2021 International Hv Recall

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 equipped with an automatic transmission and the auto neutral feature, when the engine RPM increases for the stationary power take off (PTO), it can overcome the parking brake if the transmission is in drive or reverse gear. As a result, the truck may move suddenly.

Sudden and unexpected movement of the truck could increase the risk of a crash.

The company will notify owners by mail and instruct you to take your truck to a dealer to update the body control module (BCM) software.

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 fuel rail assembly could develop a leak. Note: This recall only affects trucks equipped with a Cummins L9 or ISX12 diesel engine.

A fuel leak can create the risk of a fire.

Cummins will notify owners by mail and instruct you to take your truck to a Cummins authorized service center to inspect the fuel rail. If damage is found, the fuel rail and fuel lines will be replaced. If no damage is found, the fuel rail will be reassembled with new crush washers.

On certain trucks, a check valve within the air brake system may not have been assembled correctly. As a result, there could be an air pressure leak if there is a secondary brake circuit failure. This could cause the parking brakes to apply suddenly. Note: This recall only affects trucks built with a Bendix air brake system and an SR-7 spring brake modulating valve.

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 replace the SC-3 check valve (which is a part of the SR-7 spring brake modulating valve).

On certain trucks equipped with an automatic transmission, when the engine RPM increases for the stationary power take off (PTO), it can overcome the parking brake if the transmission is in drive or reverse gear. As a result, the truck may move suddenly.

Sudden and unexpected movement of the truck could increase the risk of a crash.

The company will notify owners by mail and instruct you to take your truck to a dealer to update the engine control module software to enable the PTO neutral interlock.

On certain trucks, the welds that attach the trailer hitch may crack due to improper welding. As a result, the hitch could detach from the truck while towing a trailer. Note: This recall only affects certain trucks with trailer hitches installed by Commercial Truck Equipment.

A trailer that detaches from a truck could create a risk of a crash.

Commercial Truck Equipment will notify owners by mail and instruct you to take your truck to a dealer to inspect the trailer hitch and repair or replace it, as necessary. You should stop using the trailer hitch until the inspection and repair have been completed.

On certain vehicles equipped with a Cummins B6.7 diesel engine, the electric fuel heater could overheat and melt. Note: This recall replaces Transport Canada recall 2019-148. Vehicles that were repaired under that recall also require this repair.

A fuel heater that overheats could create the risk of a fire. This could also cause the engine to stall, increasing the risk of a crash.

Cummins will notify owners by mail and instruct you to take your vehicle to a Cummins authorized service center to disable the fuel heater. The fuel heater will be replaced by installing a plug in its place. Additionally, the fuse supplying electrical power to the fuel heater will be removed and a cover will also be installed over the wire harness connector.
