2018 Kenworth T680 recalls

• Steering#2022210April 25, 2022

  985 units affected

  Issue: On certain trucks, the fasteners that attach the steer arm to the steering knuckle may fail. If this happens, the steer arm could separate from the steering knuckle and cause a loss of steering control. Note: This recall only affects trucks equipped with a Dana D-series steer axle. Safety Risk: A loss of steering control could increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail. The corrective actions for this recall are under development.

• Brakes#2020461September 29, 2020

  20 units affected

  Issue: Certain trucks were built with a standard rear brake ABS modulator valve instead of a quick release valve. This could result in an increased stopping distance. Note: This recall only affects certain trucks equipped with WABCO 6S/6M ABS brake systems and drum brakes. Safety Risk: An incorrect ABS modulator valve can cause increased stopping distances and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a Kenworth dealer to replace the standard rear brake ABS modulator valves with quick release ABS modulator valves.

• Lights And Instruments#2020148April 7, 2020

  65,284 units affected

  Issue: On certain trucks, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on. Safety Risk: If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).

• Seats And Restraints#2018702December 13, 2018

  758 units affected

  On certain vehicles, the webbing on certain seat belt buckle assemblies may not have been securely fastened during assembly. As a result, in the event of a crash, the seat belt may fail to restrain the seat occupant, increasing the risk of injury. Correction: Dealers will remove and replace seat belt buckle assemblies as necessary.

• Lights And Instruments#2018632November 19, 2018

  72 units affected

  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.

• Fuel System#2018527September 25, 2018

  2,974 units affected

  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#2018077February 8, 2018

  174 units affected

  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.

• Powertrain#2017664December 28, 2017

  32 units affected

  Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 102 – Transmission Control Functions. The transmission control module may allow engine cranking for around 1 second after the vehicle is powered on with the shift stalk out of neutral, contrary to the requirements of the standard. If this occurs, this could cause unintentional vehicle movement, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will update the Transmission Control Module.

• Fuel System#2017361July 20, 2017

  533 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.

• Fuel System#2017093February 20, 2017

  23 units affected

  On certain vehicles equipped with 2017 emissions engines, a tee fitting in the fuel supply was improperly manufactured and could leak fuel. Leaking fuel, in the presence of an ignition source, could result in a fire causing injury and/or damage to property. Correction: Dealers will inspect and replace affected fittings as necessary.

  PACCAR Incorporated (PACCAR) is recalling certain 2016-2021 Kenworth T680 trucks equipped with a 2.1m Cab and WABCO 6S/6M ABS brake system with drum brakes. The brake systems were manufactured with a standard rear-brake ABS modulator valve instead of a quick release valve, which may exceed the intended service-brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

  Risk: Longer than expected service-brake release timing may lengthen vehicle stopping distance, increasing the risk of a crash.
