Recall 2020148 [Canada]: Lights and instruments
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).
Recall 2018389 [Canada]: Brakes
Certain vehicles may fail to conform to the requirements of canada motor vehicle safety standard (cmvss) 121 - air brake systems and cmvss 136 - electronic stability control systems for heavy vehicles. In the event that the anti-lock brake system (abs) loses battery and/or ignition power to the controller, the abs indicator lamp may not illuminate to warn the driver of the loss of abs, which is contrary to the requirements of the standards. This could result in the loss of abs function with no warning to the driver, which could increase the risk of a crash causing injury and/or damage to property. Correction: dealers will reprogram the cab control module.
Recall 2015316 [Canada]: Lights and instruments
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.
Recall 2015190 [Canada]: Electrical
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.
Recall 2015189 [Canada]: Electrical
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.
Recall 2014590 [Canada]: Brakes
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. These issues could increase the risk of a crash causing injury and/or property damage. Correction: dealers will replace the brake chambers.
Recall 2014512 [Canada]: Electrical
On certain vehicles, an undersized wire in the trailer stop lamp circuit of the instrument panel harness is susceptible to thermal cycling which may cause damage to the wiring. This could result in the trailer lamp fuse failing, which could cause stop lamps to become inoperative and increase the risk of a crash. This damaged wiring could also increase the risk of fire. These issues could result in injury and/or damage to property. Correction: dealers will replace the undersized wire in the harness.
Recall 2014046 [Canada]: Engine
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.
