The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Risk: Insufficient air volume can reduce braking performance and increase the risk of a crash.
Fix: Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.
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.

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.

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.

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.
Service brakes, hydraulic:foundation components:differential proportional valve
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T370 long wheelbase vehicles with larger rear axle spacing.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Risk: Increased brake activation timing may lengthen vehicle stopping distance, increasing the risk of a crash.
Fix: PACCAR will notify owners, and Kenworth dealers will install a second R12 relay valve, free of charge. PACCAR issued owners an interim notification on April 14, 2020. The recall began May 6, 2020. Owners may contact Kenworth customer service at 1-425-828-5888. PACCAR's number for this recall is 20KWA.
Service brakes, air:controls:foot control/valve
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T270 and T370 vehicles. The brake treadle valves may have loose compression fittings, which can cause the air supply hose to separate from the valve.
Risk: A separated hose may cause reduced braking ability, increasing the risk of a crash.
Fix: PACCAR will notify owners, and dealers will inspect the brake treadle valve hose connections for loose compression fittings, tightening them as necessary, free of charge. The recall began September 30, 2019. Owners may contact Kenworth customer service at 1-425-828-5888. PACCAR's number for this recall is 19KWD.
