Service brakes, air:supply:reservoir/tank
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2009-2020 Kenworth T370, 2014-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, and 2009-2019 Kenworth W900 vehicles. 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.
Fix: Dealers will replace and torque the steer arm fasteners, at no charge. Owner notification letters were mailed November 8, 2022.

The methane detection system will not function if the system loses power.
Risk: The operator may be unaware of a system malfunction or the presence of excessive methane levels, increasing the risk of injury or fire.
Fix: Dealers will re-wire the warning alarm, free of charge. Owner notification letters were mailed December 1, 2022. Owners may contact Peterbilt customer service at 1-940-591-4220, and Kenworth customer service at 1-425-828-5888. PACCAR's numbers for this recall are 21KWH and 21PBN.
Service brakes, air:antilock
Problem: 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.
Fix: PACCAR will notify owners, and dealers will replace the standard rear-brake, ABS modulator valve with a quick release valve, free of charge. The recall began November 30, 2020. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 20KWD.
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.
Parking brake
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2018-2020 T680 and T880 tandem axle vehicles equipped with a parking brake on a single axle and certain models of automated manual transmissions. During cold temperatures, the signal from the park brake pressure switch to the transmission controller may be delayed possibly resulting in the vehicle moving unexpectedly.
Risk: Unexpected vehicle movement may increase the risk of a crash or injury.
Fix: PACCAR will notify owners and dealers will replace the park brake pressure switch, free of charge. PACCAR issued owners and interim notification on June 3, 2019. The recall began August 6, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 19KWB.
Power train:clutch assembly
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.
Risk: Unintended movement of a vehicle can increase the risk of a crash.
Fix: PACCAR will notify owners, and dealers will update the transmission control module, free of charge. The recall began February 23, 2019. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's numbers for this recall are 18PBE and 18KWH.
Exterior lighting
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2013-2019 Kenworth T680 and T880 and Peterbilt 579 trucks, greater than 30 feet long and equipped with side extender mounted intermediate marker lamp/turn signals that do not include a reflex reflector. Since both intermediate side marker lamps and reflex reflectors are required, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.
Fix: PACCAR will notify owners and dealers will install reflex reflective tape, free of charge. The recall began January 15, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWF, and 18PBC.
Engine and engine cooling:engine:diesel
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2017-2019 Kenworth C500, T600, T660, T680, T800, T880 and W900 trucks, as well as Peterbilt 367, 386, 389, 567, 579 and 587 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
Risk: If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.
Fix: Cummins will notify owners, and dealers will replace the suspect fuel pump cooling circuit screen, free of charge. The recall began November 21, 2018. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 18E081.
