Issue: On certain trucks, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on. Safety Risk: If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).
Certain vehicles equipped with HID headlamps may not comply with the requirements of Canada Motor Vehicle Safety Standard 108 - Lighting System and Retroreflective Devices. A Daytime Running Lamp (DRL) that is optically combined with a turn signal lamp must switch off when the turn signal lamp is switched on as a hazard warning signal. In the affected vehicles, the DRL overrides the hazard flashing functionality after the service brake is applied for more than 2 seconds, which is contrary to the standard. The hazard functionality returns to normal when the application of the service brake is removed. Turn signal functionality would not impacted. Failure to warn oncoming vehicles with flashing hazard lamps could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update vehicle software.
On certain vehicles equipped with PACCAR MX-13 engines and Delco-Remy 40SI alternators, the alternator charge cable may chafe against an air conditioning discharge line. This chafing could lead to damage of the alternator cable's insulation and could lead to an electrical short, increasing the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will rotate the alternator cable end 180 degrees to provide necessary clearance and reattach the cable to the alternator.

On certain vehicles, water could migrate into wiper motor head and could lead to internal corrosion. This internal corrosion could form a conductive salt bridge which could result in a short circuit, causing the wiper system to fail. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, and a short circuit could increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will install a shield over the wiper motor to protect it from water intrusions and prevent corrosion.
On certain vehicles equipped with a Wabco quick release with double check valves, used to control park/spring brake application, the valve may leak internally. This could cause unintended partial or full park/spring brake application, which could affect service brake function and increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will affect repairs.
On certain vehicles equipped with Cummins ISL G or ISX12 G 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.
On certain vehicles, the seat belts may not comply with Canada Motor Vehicle Safety Standard 209 - Seat Belt Assemblies. Due to a defect in manufacturing, the seat belt buckle may not release as required by the standard. This could hinder egress from the vehicle in an emergency, increasing the risk of injury. Correction: Dealers will inspect and, if necessary, replace affected seatbelt buckles.
The stop/turn/tail lights used on certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices. The plastic lamp housing may shrink, causing the light to fall out of the light retention ring . In this situation, the light would no longer comply with the mounting requirements of CMVSS 108 and visibility to other motorists would be affected. This could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace affected lights.
On certain trucks, an internal defect in the ignition switch can cause the starter to engage when the key is partially inserted. This would allow the engine to start unexpectedly, which could injure someone working in the engine compartment. Also, manual transmission vehicles without the neutral start option may move unexpectedly if the transmission is in gear at the time the key is inserted. This could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the ignition switch assembly.
