Transport Canada recalls
15- Fuel System#2024580
76 units affected
Issue: On certain trucks equipped with a Cummins X15 engine, the fuel pump may not have been manufactured properly. As a result, the fuel pump barrels could break and cause a fuel leak. If this happens, the engine could stall. Safety Risk: A sudden loss of engine power could increase the risk of a crash. Corrective Actions: Cummins will notify owners by mail and advise you to take your vehicle to a Cummins authorized service facility to replace the fuel pump barrels.
- Brakes#2024006
69 units affected
Issue: On certain trucks, the inversion valve in the air brake system may not work properly. As a result, there could be a delay before the parking brake applies. If this happens, the vehicle could move unexpectedly. This issue also causes the vehicle not to meet the requirements of the Canadian regulations. Safety Risk: A delay before the parking brake applies could result in unintended vehicle movement, and create the risk of an injury or a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify the owners by mail and advise you to take your truck to a DTNA authorized service facility to inspect and, if necessary, replace the inversion valve.
- Electrical#2021697
3,071 units affected
Issue: On certain trucks, the pass-through power stud (an electrical connection located on the bulkhead) may come into contact with the bulkhead. If this happens, there could be electrical arcing (sparks). Note: This recall replaces FL-766 (Transport Canada Recall 2018-190). If your truck was inspected as a part of that recall, but the pass-through power stud was not replaced, your truck requires this repair. Safety Risk: Electrical arcing could create the risk of a fire. Corrective Actions: Daimler Trucks North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to replace the pass-through power stud.
- Brakes#2019237
110 units affected
Issue: Certain trucks were built with air reservoir tanks that are too small in relation to the size of the air brake chambers. Canadian regulations require enough air reservoir capacity to ensure the brakes work even with heavy use or when there is a partial loss of the air system. Safety Risk: Reduced braking could cause extended stopping distances and increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their truck to a Daimler Trucks North America authorized service facility to modify the truck to ensure it meets Canadian regulations.
- Accessories#2017636
16,510 units affected
On certain vehicles equipped with Kidde fire extinguishers with black plastic handles and valves, the fire extinguishers may become clogged or require excessive force to activate. Also, the nozzle may detach from the valve assembly with enough force that it could cause injury, and fail to discharge. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: Owners will be provided with instructions on how to inspect the fire extinguisher to see if it is recalled. Replacement fire extinguishers will be supplied by Kidde directly. Note: For more information about recalled fire extinguishers, please visit <a href="https://inmarmarketaction.com/kidde/Kidde284CA/">www.kidde.com</a>.
- Brakes#2017583
41,763 units affected
On certain vehicles with air brakes, after several hard brake applications, the brake light pressure switch may not activate the brake lights with a light application of the brake pedal. If the brake lights do not illuminate, following road users would be unaware of the intent of the driver to slow the vehicle, which could increase the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks North America authorized service facilities will repair the brake light pressure switch.
- Fuel System#2017358
38 units affected
On certain vehicles equipped with Cummins ISX 15 engines and certain fuel pumps, the drive gear on the fuel pump may spin loose on the drive shaft. This could result in a loss of pumping function, which could result in an engine stall without warning and not being able to be restarted, which could increase the risk of a crash causing injury and/or damage to property. Correction: Cummins-authorized dealers will replace the fuel pump.
- Visual System#2015251
219 units affected
Certain vehicles may not comply with Canada Motor Vehicle Safety Standard (CMVSS 101) – Location and Identification of Controls and Displays. These vehicles may have been manufactured with an odometer displaying imperial measurements instead of metric. Correction: Dealers will install a new speedometer with a metric odometer and the correct software.
- Accessories#2015133
1,403 units affected
On certain vehicles, the handheld Kidde plastic valve disposable fire extinguisher may not function as designed. In certain instances, the extinguisher may fail to fully discharge when the lever is pressed multiple times. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: A replacement extinguisher will be provided by dealers or Kidde directly.
- Seats And Restraints#2013427
2,888 units affected
On certain trucks, the seat belts may not comply with Canada Motor Vehicle Safety Standard 209 - Seat Belt Assemblies. Due to a defect in manufacturing, the seat belt buckle may not release as required by the standard. This could hinder egress from the vehicle in an emergency, increasing the risk of injury. Correction: Dealers will inspect and, if necessary, replace affected seatbelt buckles.
- Fuel System#2012080
11,923 units affected
On certain trucks equipped with a Detroit Diesel DD13, DD15 or DD16 engine, the support system for the high pressure fuel line (between the fuel pump and the fuel delivery rail) may be damaged during a service repair procedure. Incorrect torque applied to the dampener "P" clip fasteners may damage the fasteners, which could allow the clips to loosen. This could result in a cracked fuel line and a diesel fuel leak. Diesel fuel leakage may ignite on a hot engine surface and cause a fire. As well, diesel fuel spilt on the roadway could endanger other road users by making the roadway unexpectedly slippery. These issues could result in property damage and/or personal injury. Correction: Dealers will replace the high pressure fuel line and install a more robust fuel line support system.
- Electrical#2011236
5,924 units affected
On certain trucks equipped with a DD15 or DD16 engine, the bolt attaching a rubber isolator to a support bracket may become loose, back out, and contact the starter cable. This could cause an electrical short, which could result in a fire causing property damage and/or personal injury. Correction: Dealers will install a new bolt and isolator, and apply thread-locking fluid to the fastener.
- Powertrain#2011172
81 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#2011163
297 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.
- Engine#2009270
5,647 units affected
On certain vehicles equipped with a Caterpillar C15 engine, the Variable Valve Actuation (VVA) oil line may wear against the P-clip retaining the oil line. An oil leak could result in a vehicle fire causing property damage and/or personal injury. Correction: Caterpillar dealers will replace the VVA oil line with an updated version.
