Transport Canada recalls

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#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.
Lights And Instruments#2014146April 22, 2014
5,990 units affected
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.
Electrical#2014053February 21, 2014
2,462 units affected

Other#2011261July 21, 2011
76 units affected
On certain trucks, the clutch pedal assembly may have been manufactured incorrectly and could fail. This could allow the clutch pedal to fall to the floor, prohibiting clutch operation, and causing a reduction in braking efficiency. Increased stopping distances could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the clutch pedal assembly.
Brakes#2011182May 2, 2011
329 units affected
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.
Other#2011146March 31, 2011
42 units affected
On certain trucks, the bolts used to secure the fifth wheel hitch assembly to the frame may not have received adequate tightening torque during vehicle assembly. This could allow the mounting bolts to fail and the fifth wheel assembly, as well as the trailer, to separate from the tractor. A towed unit separating from the towing vehicle could strike another vehicle, stationary object, or bystander, causing property damage and/or personal injury. Correction: Dealers will inspect the mounting bolts and replace as required.
Visual System#2010371October 27, 2010
3 units affected
On certain vehicles, the rear conspicuity reflector typically found on the mud flap hanger brackets may not have been installed in the back of the cab which is the alternate position allowed for vehicle manufactured without mud flap hanger brackets. Missing reflector is a non-compliance with Canada Motor Vehicle Safety Standards 108 - Ligthing System and Retroreflective Devices. Correction: Dealers will inspect and if missing will install the required reflectors.
