2018 International Prostar recalls

• Lights And Instruments#2023293May 18, 2023

  1,764 units affected

  Issue: 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. Safety Risk: 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. Corrective Actions: 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.

• Heater And Defroster#2023212April 6, 2023

  3,134 units affected

  Issue: On certain trucks, a wire terminal for the blower motor circuit breaker in the power distribution module (PDM) could overheat and melt. Safety Risk: Wiring that overheats and melts can create the risk of a fire. Corrective Actions: Navistar will notify owners by mail and instruct you to take your truck to a dealership to replace the blower motor wiring terminal in the PDM. The dealership will also inspect and, if necessary, replace the fuse block.

• Structure#2019085February 22, 2019

  2,337 units affected

  Issue: On certain vehicles, the exhaust hanger brackets may crack and allow the tail pipe to separate from the vehicle. Safety Risk: If the exhaust tail pipe falls off, it could become a hazard for road users and bystanders. This could create a risk of injury and/or a crash. Corrective Actions: The company will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to have the rear exhaust hanger bracket replaced. Dealers will also inspect and replace any forward bracket found cracked and/or tail pipe that is damaged.

• 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).

• Engine#2018475September 5, 2018

  3,970 units affected

  On certain trucks built with a Cummins X15 or ISX15 engine equipped with nylon fuel lines and a banjo bolt on the fuel pump, a blockage in the fuel cooling system may cause a fuel line to burst. This could result in a significant fuel leak onto the roadway, which would create a road hazard for other motorists. Additionally, this condition could also cause an engine stall without warning, without the ability to restart the engine. Both of these conditions may increase the risk of a crash causing injury and/or damage to property. Correction: Cummins-authorized dealers will replace the affected nylon line with a steel line.

• 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. If this occurs, the seat belt may not properly restrain the seat occupant in a crash, increasing the risk of injury. Correction: Dealers will inspect the driver and passenger D-ring mounting bolts and replace them as necessary.
