Date: 2022-04-25. Systems: STEERING.
Defect: 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: Fastener failure can result in a loss of steering control, increasing the risk of a crash or injury.
Remedy: 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.

Date: 2021-11-19. Systems: ELECTRICAL SYSTEM, SERVICE BRAKES, AIR.
Defect: PACCAR Incorporated (PACCAR) is recalling certain 2019-2022 Kenworth T880, W990, Peterbilt 567, 579, 389, and 2022 Peterbilt 536, 537 wrecker and auto hauler vehicles. The work brake (winch brake) may unintentionally disengage the service brakes during winching operations, causing the vehicle to roll.
Consequence: Unintended vehicle movement can increase the risk of a crash or injury.
Remedy: Dealers will update the vehicle software, free of charge. Owner notification letters were mailed on January 3, 2022. 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 21KWG and 21PBM.

Date: 2020-08-26. Systems: POWER TRAIN.
Defect: PACCAR Incorporated (PACCAR) is recalling certain 2020-2021 Peterbilt 348, 365, 367, 389, 520, 567 and Kenworth T800, T880, W900, W990 vehicles equipped with Watson and Chalin steerable lift axle suspension systems (model SL2065). The axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts.
Consequence: The short screws can cause the hardware to separate from the suspension system and become road hazards, increasing the risk of a crash and/or injury.
Remedy: PACCAR will notify owners, and dealers will inspect suspect chassis and replace the pivot bolts, as necessary, free of charge. The recall began September 29, 2020. 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 is 20PBE and 20KWC.

Defect: PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T800, T880 and W990 and Peterbilt 348, 367, 389, 520, and 567 vehicles. The forward rear axle output shafts may have been improperly heat treated during manufacturing, possibly resulting in the shafts fracturing.
Consequence: If the rear axle output shaft fractures, the shaft or interaxle driveline could detach and become a road hazard, increasing the risk of a crash.
Remedy: PACCAR will notify owners, and dealers will inspect and replace the output shafts, as necessary, free of charge. The recall began February 19, 2020.
