Certain vehicles may have been built with an incorrectly sized alternator cable. This could potentially result in the cable overheating, which may increase the risk of a vehicle fire causing injury and/or damage to property. Correction: Dealers will replace the alternator cable.
A failure of this component (electrical) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain vehicles equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly elbow to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the elbow of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.
A failure of this component (engine) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain vehicles, the directional/hazard signal flasher may fail. Actuation of the turn signal or hazard lights in this condition would cause them to remain illuminated and not flash as intended. As a result, drivers may not be able to clearly signal their intentions to turn, change lanes or warn others in an emergency situation. Correction: Dealers will replace the turn signal/hazard flasher module.
A failure of this component (lights and instruments) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain vehicles equipped with Cummins compressed natural gas engines, incorrect engine ECU programming could cause the exhaust system temperature to become elevated during cold weather operation. This could also cause flames to be emitted from the exhaust. As a result, nearby combustible material could be ignited, increasing the risk of a fire, injury and/or damage to property. Correction: Authorized Cummins service facilities will update software programming.
A failure of this component (engine) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain trucks, the front axle beam may have been manufactured incorrectly. In certain application the load on the axle could allow stress cracks to form which, over time, may cause the axle beam to fail. This could result in a vehicle crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if required, replace the axle beam.
A failure of this component (suspension) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain trucks, the steering gear mounting bolts may not have received adequate tightening torque during vehicle assembly. Should the bolts loosen, the steering gear could separate from its mounting bracket, which may affect steering performance. A loss of steering control could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the steering gear mounting bolts.
A failure of this component (steering) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain vehicles, the slack adjuster housings may have been manufactured incorrectly, which could allow the housings to fracture and fail. As a result, the wheel brake to which the slack adjuster is attached would no longer function, which could increase vehicle stopping distances. Should a steer axle slack adjuster fail, it could also cause the vehicle to pull to one side during braking. Either problem could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the slack adjusters.
A failure of this component (brakes) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain vehicles, the rearview mirror switch (mounted on the dashboard) may overheat, causing the plastic to melt. An overheated switch may not allow rearview mirror remote adjustability and, as such, the driver may not have full use of the mirrors. In addition, excessive heat can cause smoke within the instrument panel, which could distract the vehicle operator and result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect the rearview mirror switch and install a relay wiring harness. Switches that show signs of overheating will be replaced.
