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.
Powertrain#2016079February 18, 2016
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.
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
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.
Visual System#2012194June 29, 2012
66 units affected
On certain vehicles, the hardware used to affix the windshield wiper linkage to the wiper motor may have been subject to rust and corrosion before assembly. This contamination may have prevented the bolt/nut from being tightened adequately. As a result, the bolt/nut may loosen to a point where the linkage detaches from the wiper motor, which would cause the wipers to stop functioning. 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, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the hardware in question.
Suspension#2011409November 18, 2011
19 units affected
On certain trucks, the drive axle tower bracket may not have been welded correctly during the manufacturing process. This could allow the bracket to detach from the axle, which could result in a loss of vehicle control and a crash causing property damage and/or personal injury. Correction: Authorized service facilities will inspect and, if necessary, repair weld the axle assembly.
Powertrain#2011205May 19, 2011
584 units affected
On certain trucks, the driveshaft may not have been welded correctly during the manufacturing process. This could allow the driveshaft to fracture along the length of the tube seam weld when torque is applied. The fractured tube can twist or sever, which could result in additional damage to the driveline, the vehicle to which it is attached, and any additional nearby components. Should the brake air lines become damaged, it could allow spring brake application, causing immediate brake lock-up. If this occurs while the vehicle is in motion, it could result in a crash. Also, failure of the driveshaft would result in lost vehicle propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Either condition could result in property damage and/or personal injury. Correction: Dealers will replace the driveshaft 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.
