22V277000SteeringApril 25, 2022 · 17,641 units

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.

21V391000Fuel SystemMay 26, 2021 · 612 units

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.

20V506000TransmissionAugust 26, 2020 · 1,097 units

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.
