On certain trucks, the intermediate side marker lamp/turn signals do not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices. The intermediate side marker lamp/turn signals, mounted to the side extenders, do not include the required reflex reflectors. This could decrease vehicle conspicuity and potentially increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will install reflex reflective tape to the side extender near the intermediate side marker lamps.

2017 Kenworth T680 Recall 2018527 25 Sep 2018 2,974 units in Canada

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.

Lights And Instruments

Certain vehicles equipped with Eaton Ultrashift Plus or Eaton Advantage automatic transmissions with right hand stalk shifters may not comply with the requirements of Canada Motor Vehicle Safety Standards (CMVSS) 101 - Location and Identification of Controls and Displays and CMVSS 102 – Transmission Control Functions. Under certain conditions, the D-R-N (Drive-Reverse-Neutral) display in the instrument cluster may incorrectly illuminate the "N" on the display when the transmission shifter is in the "D" or "R" position, which is contrary to the requirements of the standards. This could create confusion to the operator, which could increase the risk of injury and/or property damage. Correction: Dealers will update the transmission software.
