• 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.
