2020 Kenworth W900 recalls

• Brakes#2024121February 23, 2024

  171 units affected

  Issue: On certain trucks, the reservoir tank for the air brake system is too small. In certain situations, this could cause reduced braking. 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. Safety Risk: Reduced braking can cause extended stopping distances and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to replace or add an additional air reservoir tank, as necessary.

• Seats And Restraints#2023573October 26, 2023

  1,532 units affected

  Issue: On certain trucks, a spacer installed between the seat frame and the seat belt buckle may cause the seat belt to slip and not to work properly in a crash. Safety Risk: A seat belt that doesn't work properly could increase the risk of injury in a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to remove the spacer(s) and replace the bolt(s).

• 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.

• Suspension#2020399August 27, 2020

  502 units affected

  Issue: On certain trucks, the lift axle pivot bolts may be too short and may not be properly tightened. As a result, the bolts could come loose or break. If this happens, parts could fall from the truck. Note: This recall only affects trucks built with Watson Chalin SL2065 lift axles. Safety Risk: Large fasteners that fall on the road could create a road hazard for others and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to inspect and replace the lift axle pivot bolts, as necessary.

• 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).

• Powertrain#2019118March 7, 2019

  2 units affected

  Issue: On certain trucks, the rear axles may not contain any oil. This may result in accelerated bearing, hub and axle shaft wear. This wear could cause a separation of a wheel end (hub, wheel, and tires) from the truck. Safety Risk: The separation of a wheel end could increase the risk of a crash. Wheels that separate could also strike another road user. Corrective Actions: The company will notify owners by mail. Owners will be instructed to take their truck to a dealer to have the rear axle oil level inspected. If no oil is present, all wheel ends will be removed and bearing, hub and axle shafts inspected for damage. If excessive wear or heat damage is found, the parts will be replaced. The axles will be filled with the correct amount of oil.

In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

  Risk: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

  Risk: Without lubricating oil, the bearings, hub and axle shafts may wear, resulting in the separation of a wheel end from the axle, increasing the risk of a crash.
