Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a Peterbilt dealer to install additional conspicuity tape on the back wall of the sleeper box, in the required locations.

Visual System

Issue: On certain trucks, the upper glass on the side mirrors may not be properly attached. This could cause the mirror glass to fall off or to hang from its wiring and block the lower convex mirror. Safety Risk: Missing or blocked mirrors will reduce visibility and increase the risk of a crash. If the mirror glass falls from the vehicle, it could strike another vehicle or pedestrian. Corrective Actions: The company will notify owners by mail and instruct them to take their truck to a dealer to inspect the build date of upper mirror glass assembly. The mirror glass will be replaced as necessary.

Powertrain

On certain vehicles equipped with an Eaton automated manual transmission and electronic clutch actuator (ECA), the clutch may have been manufactured improperly and could fail. If this occurs, the broken clutch components could prevent the transmission from disengaging or shifting to neutral. This could result in unintended vehicle movement, even if the parking brake is applied, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will recalibrate the Transmission Control Module (TCM).

Fuel System

On certain trucks built with a Cummins X15 or ISX15 engine equipped with nylon fuel lines and a banjo bolt on the fuel pump, a blockage in the fuel cooling system may cause a fuel line to burst. This could result in a significant fuel leak onto the roadway, which would create a road hazard for other motorists. Additionally, this condition could also cause an engine stall without warning, without the ability to restart the engine. Both of these conditions may increase the risk of a crash causing injury and/or damage to property. Correction: Cummins-authorized dealers will replace the affected nylon line with a steel line.

Brakes

Certain vehicles may fail to conform to the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 121 - Air Brake Systems and CMVSS 136 - Electronic Stability Control Systems for Heavy Vehicles.

This could result in the loss of ABS function with no warning to the driver, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will reprogram the cab control module.
