• Brakes#2017291June 2, 2017

  147 units affected

  Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 121 - Air Brake Systems. Clamps securing the front brake hoses may have been over-tightened at time of assembly. This could distort the brake hoses, potentially causing damage and leaks. If a leak occurs, it would cause delay brake actuation, and could cause the vehicle to fail to conform to the standard. A delay in brake actuation would increase stopping distances, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and repair air hoses and clamps as necessary.

• Brakes#2016479September 29, 2016

  8 units affected

  Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard 121 - Air Brake Systems. Due to an error in programming, the low air pressure audible and visual warnings may not occur during a low pressure event, contrary to the requirements of the Standard. In the event of a loss of air pressure in the rear air tank (primary) system, the audible and visual warnings notifying the operator of a condition that could result in reduced service brake performance, or unexpected application of the parking brakes, may not occur. Continued operation of the vehicle with a low primary air system condition could increase the risk of a crash causing injury and/or damage to property. Correction: The manufacturer's field service organization will reprogram affected vehicles. Note: The dashboard mounted air pressure gauge does display the correct system air pressure.
