Transport Canada recalls

Powertrain#2016495October 11, 2016
1,690 units affected
On certain vehicles, the cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may prematurely loosen. If the nut were to loosen and come off, the yoke could separate from the axle input shaft and cause the drive shaft to disconnect. A disconnected drive shaft would result in a loss of motive power, and create a road hazard, both of which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the torque on the cap nut, and the nut will be replaced if the torque is found under specification. Note: This is an expansion of recall 2016-079.

1,068 units affected
On certain vehicles, the cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may prematurely loosen. If the nut were to loosen and come off, the yoke could separate from the axle input shaft and cause the drive shaft to disconnect. A disconnected drive shaft would result in a loss of motive power, and create a road hazard, both of which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the cap nut, and inspect the threads on the input shaft. If the threads are damaged, the input shaft will be replaced.
Brakes#2015372August 17, 2015
241 units affected
On certain vehicles, The chassis electrical harness and air brake lines may not have been properly secured at the crossmember. This could cause the electrical cables and air lines to fall down and get twisted in the driveline. This could affect safety systems such as brakes, increasing stopping distances or causing unintended parking brake application. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and repair the vehicle as needed.
Accessories#2015100March 10, 2015
71 units affected
On certain vehicles, the fifth wheel remote unlocking switch may not work as designed. As a result, the driver may inadvertently release the 5th wheel latch when the park brake is applied if he/she presses or bumps the switch. This could cause the trailer to decouple from the truck increasing the risk of injury and/or damage to property. Correction: Dealers will add a redundant measure such as an additional switch or adding a thumb lock that requires 2 actions to push the switch.
Electrical#2015017January 16, 2015
32 units affected
On certain model vehicles outfitted with an Automatic Over-Speed Protection system, the system may be incorrectly wired. This presents a potential risk as the operator may not be able to control an unintended increase in the engine RPM if combustible vapors enter through the air intake. If this occurs, it could increase the risk of an engine fire that may cause injury and/or property damage. Correction: Dealers will inspect and repair accordingly.
Electrical#2014527November 20, 2014
11,668 units affected
On certain model vehicles, water around the windshield can migrate into the Electronic Power Distribution Module and contaminate it. As a result, circuits may be bridged creating an electrical short. This could potentially result in a fire, increasing the risk of injury and/or damage to property. Correction: Dealers will inspect the module, and if found contaminated, will replace it. Additional measures will be taken to address the leak if contamination is found. Note: This is an expansion of recall 2014-053.
Suspension#2014526November 20, 2014
33 units affected
On certain vehicles, the collars that prevent the ball sockets from backing out of the tie rod may have been incorrectly positioned. If the ball socket(s) became loose, a complete loss of steering or loss of steering at one wheel end could occur, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect, and if necessary, reposition the collar.
Seats And Restraints#2014390September 9, 2014
46 units affected
On certain vehicles, bolts securing the seat belts to the seat frame, cab wall and cab floor may have been insufficiently tightened during vehicle assembly. As a result, bolts could loosen over time and potentially allow the seat belt to detach from its mounting points. If this occurs, the seat belt may fail to restrain the seat occupant in a crash, increasing the risk of injury and/or damage to property. Correction: Dealers will tighten the affected bolts to the specified torque.
