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.
Reduced braking could cause extended stopping distances and increase the risk of a crash.
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.
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 www.kidde.com.

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.
