• Powertrain#2017664December 28, 2017

  32 units affected

  Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 102 – Transmission Control Functions. The transmission control module may allow engine cranking for around 1 second after the vehicle is powered on with the shift stalk out of neutral, contrary to the requirements of the standard. If this occurs, this could cause unintentional vehicle movement, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will update the Transmission Control Module.

• Steering#2017461September 25, 2017

  281 units affected

  On certain vehicles, the castellated nut and cotter pin on the steer axle may not have been tightened to specification. This could cause the tie rod to become loose in the steer axle, which would result in audible noise and/or looseness in steering. If the vehicle were continued to be operated in this condition, the tie rod could disconnect from the knuckle, resulting in a complete loss of control of a vehicle wheel, which would increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the torque of the castellated nuts on the tie rod, and replace the tie rod stud and knuckle as necessary.

• Electrical#2017374July 27, 2017

  240 units affected

  On certain vehicles, the polyfuse for the spotlight could develop a short circuit in the cabin fuse box.

• Engine#2016289June 8, 2016

  178 units affected

  On certain vehicles, the Engine Control Module (ECM) may develop an internal electrical short circuit that could blow a fuse in the ECM's electrical supply circuit. This could cause the engine to stall without warning and prevent the vehicle from being restarted. Engine stalling without warning would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ECM.

• Engine#2015418September 23, 2015

  9 units affected

  On certain vehicles equipped with a Cummins engine, the Engine Control Module (ECM) could develop an internal electrical short circuit that could blow a fuse in the ECM’s electrical supply circuit. This could result in an unexpected engine stall without the ability to restart the engine, which could increase the risk of a crash. Correction: Dealers will replacing the existing, affected ECM with a new ECM.

• Brakes#2015318July 20, 2015

  32 units affected

  Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard 121 - Air Brake Systems. The two service brake connections of the SR-7 spring brake valve assembly that provide the valve with feedback from the primary and secondary service brake applications may have been reversed during installation. Although the SR-7 valve would still function properly if there were normal reservoir pressure, in the event of a failure in the primary or secondary circuit, the redundant circuit would not provide adequate service brake functionality, and the vehicle would fail to meet the emergency brake system performance standard. This could result in reduced braking performance which could result in a vehicle crash. Correction: Dealers will inspect, remove and reconnect the air lines to the correct port of the SR-7 valve.

• Lights And Instruments#2015316July 20, 2015

  4,791 units affected

  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.

• Electrical#2015190May 8, 2015

  22,815 units affected

  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.

• Electrical#2015189May 8, 2015

  140 units affected

  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.

• Wheels#2015188May 8, 2015

  3 units affected

  On certain vehicles, the wheel nuts may have been insufficiently tightened during vehicle assembly. This could cause the wheel nuts to loosen and could lead to a complete separation of the wheel(s) from the vehicle, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect, and properly tighten the lug nuts to specification.

• Brakes#2014590December 23, 2014

  218 units affected

  On certain vehicles, brake chamber diaphragm(s) may not be properly seated. This could lead to brake drag, causing brake overheating or unintended spring brake application.

• Lights And Instruments#2013432December 5, 2013

  702 units affected

  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.

• Electrical#2013178May 24, 2013

  255 units affected

  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.

• Seats And Restraints#2013077March 12, 2013

  322 units affected

The label warns users that the upper bunk is not to be used while the vehicle is moving, that the bunk is to be latched in the stored and upright position when not in use, and that all front restraint buckles are to be fastened when the bunk is in the down position. It also specified the maximum weight limit of the upper bunk. If the warning label text is not readable and the user has no notice of these safety recommendations, an occupant may be injured in a crash or upon sudden vehicle deceleration. Correction: Dealers will replace the upper bunk warning label.

• Seats And Restraints#2012215July 13, 2012

  3 units affected

  On certain vehicles, the upper bunk restraint system anchors could fail during a vehicle crash.
