Steering:critical fasteners
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2018-2020 Kenworth T270, T370, T440, T470, T660, T680, T880, T800, W900, W990; and 2018-2020 Peterbilt 330, 337, 348, 365, 367, 389, 520, 567, and 579 vehicles. The Dana D-Series axle steer arm fasteners that attach the steering arm to the steering knuckle may fail.
Risk: Fastener failure can result in a loss of steering control, increasing the risk of a crash or injury.
Fix: Dealers will replace and torque the steer arm fasteners, at no charge. Owner notification letters were mailed November 8, 2022. Owners may contact Kenworth customer service at 1-425-828-5888 and Peterbilt customer service at 1-940-591-4220. PACCAR's numbers for this recall are 22 PBB and 22 KWB.
Fuel system, diesel:fuel injection system:fuel rail
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2018-2021 Peterbilt 337, 348, 365, 367, 520, 567, Kenworth T270, T370, T440, T470, T800 and T880 vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.
Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.
Fix: Dealers will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owners may contact PACCAR customer service at 1-425-828-5888 (Kenworth) or 1-940-591-4220 (Peterbilt). PACCAR's numbers for this recall are 21KWC and 21PBD.
Service brakes, air:antilock:abs warning light; electronic stability control (esc)
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. 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.
Fix: PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

Problem: PACCAR Incorporated (PACCAR) is recalling certain 2018-2019 Peterbilt 337, 348, 365, 367, 389, 567, 579 and 587 trucks and 2018-2019 Kenworth C500, T270, T370, T440, T660, T680, T800, T880 and W900 trucks equipped with automated manual transmissions. An internal component in the clutch assembly may fail, possibly resulting in unintended vehicle movement.
