  1,411 units affected

  Issue: 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. Safety Risk: 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. Corrective Actions: 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.

• Powertrain#2019592November 21, 2019

  1,806 units affected

  Issue: 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. Safety Risk: Sudden and unexpected movement of the truck could increase the risk of a crash. Corrective Actions: 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.

• Powertrain#2018638November 20, 2018

  2,856 units affected

  On certain vehicles equipped with an electronic clutch actuator (ECA), the clutch may have been manufactured improperly and could fail. If this occurs, the broken clutch components could prevent the transmission from disengaging or shifting to neutral. This could result in unintended vehicle movement, even if the parking brake is applied, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will recalibrate the Transmission Control Module (TCM).

• Brakes#2018484September 10, 2018

  198 units affected

  On certain vehicles, the spring-actuated parking brake may have been improperly assembled. This could result in an internal air leak or a complete separation of the parking brake from the service brake chamber, either of which would cause a loss of braking on the affected wheel assembly. This could cause a sudden, unexpected increase in stopping distance, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and replace affected brake chamber assemblies.

• Seats And Restraints#2018232May 3, 2018

  2,093 units affected

  On certain vehicles, the seat belt D-ring mounting bolts may break due to a material defect.
