Date: 2024-03-20. Systems: POWER TRAIN.
Defect: PACCAR Incorporated (PACCAR) is recalling certain 2021-2024 Peterbilt 365, 367, 389, 535, 536, 537, 548, 567, 579, and 2021-2025 Kenworth T180, T280, T380, T480, T680, T880 and W990 trucks. The right-hand gear shifter stalk connectors may have been improperly crimped, resulting in a loss of communication.
Consequence: A loss of communication between the gear shifter and the transmission may result in the vehicle becoming disabled after coming to a stop, increasing the risk of a crash.
Remedy: Dealers will inspect and replace the gear shifter assembly as necessary, free of charge. Owner letters were mailed December 15, 2025, then phased after that. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's numbers for this recall are 24PBE and 24KWE.
Do not drive: No. Park outside: No.
Date: 2021-05-26. Systems: FUEL SYSTEM, DIESEL.
Defect: 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.
Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: 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.

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.
