   Service Brakes, Air / Supply / Reservoir/Tank

   Defect, in the NHTSA record

   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."

   Consequence, in the NHTSA record

   Insufficient air volume can reduce braking performance and increase the risk of a crash.

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 24KWD. Owner notification date in the NHTSA record: 12 Aug 2024.

2. 22V277000Received 25 Apr 2022. 17,641 units.

   Steering / Critical Fasteners

   Defect, in the NHTSA record

   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.

   Consequence, in the NHTSA record

   Fastener failure can result in a loss of steering control, increasing the risk of a crash or injury.

   Remedy, in the NHTSA record

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.

3. 20V593000Received 28 Sep 2020. 1,416 units.

   Service Brakes, Air / Antilock

   Defect, in the NHTSA record

   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."

   Consequence, in the NHTSA record

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

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 20KWD. Owner notification date in the NHTSA record: 30 Nov 2020.

4. 20V199000Received 6 Apr 2020. 460,515 units.

   Electronic Stability Control (ESC)

   Defect, in the NHTSA record

   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."

   Consequence, in the NHTSA record

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

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 20pbc AND 20KWB. Owner notification date in the NHTSA record: 26 May 2020.

5. 19V340000Received 1 May 2019. 3,907 units.

   Visibility / Rearview Mirrors/Devices / Exterior

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2020 Peterbilt 520 and 579 vehicles and Kenworth T680, T880 and W990 vehicles. The mirror glass may detach from the mirror carrier plate due to inadequate adhesion.

   Consequence, in the NHTSA record

   If the mirror glass detaches, the driver may have reduced visibility and the mirror glass will become a road hazard that may strike another vehicle or pedestrian, increasing the risk of a crash or injury.

   Remedy, in the NHTSA record

   PACCAR has notified owners, and dealers will inspect the upper mirror glass/mirror carrier, replacing it as necessary, free of charge. The recall began May 31, 2019. Kenworth owners may contact PACCAR customer service at 1-425-828-5888 and Peterbilt owners may call 1-940-591-4220. PACCAR's numbers for this recall is 19KWC and 19PBC.

6. 19V275000Received 5 Apr 2019. 1,837 units.

   Parking Brake

   Defect, in the NHTSA record

   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.

   Consequence, in the NHTSA record

   Unexpected vehicle movement may increase the risk of a crash or injury.

   Remedy, in the NHTSA record

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 19KWB. Owner notification date in the NHTSA record: 6 Aug 2019.

7. 19V176000Received 5 Mar 2019. 93 units.

   Suspension / Rear / Axle / Non-Powered Axle Assembly

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T680, T800, T880, W900 and W990 trucks. The rear axles may not contain oil.

   Consequence, in the NHTSA record

   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.

   Remedy, in the NHTSA record

   Paccar will notify owners, and Kenworth dealers will inspect all of the rear axles for the presence of oil. If no oil is present, the wheels ends will be removed and the bearings, hub and axle shaft will be inspected for damage. If excessive wear or heat damage is evident, the components will be replaced, as necessary. Oil will then be added per the axle specifications. These repairs will be performed free of charge. The recall began April 16, 2019. Owners may contact Kenworth customer service at 1-425-828-5888. Paccar's number for this recall is 19KWA.
