2021 Kenworth W900 recalls
Recall 23V-717: Seat Belts
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T660, 2018-2024 Kenworth T800 and W900 vehicles. An additional spacer may have been added to the joint that connects the seat to the seat belt tether and buckle, causing an unsecured connection.
Risk: An unsecured seat belt connection may not properly restrain an occupant during a crash, increasing their risk of injury.
Fix: Dealers will inspect and remove the additional spacer and replace the bolt, as necessary, free of charge. Owner letters were mailed March 20, 2024. Owners may contact PACCAR's customer service at 1-425-828-5888. PACCAR's number for this recall is 23KWK.

The capscrews that attach the flywheel to the crankshaft may have been improperly torqued, allowing the flywheel to detach.
Risk: A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.
Fix: PACCAR will notify owners, and dealers will properly torque the capscrews and the engine will also be inspected for damage and, if necessary, repaired, free of charge.

The axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts.
Risk: 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.
Fix: 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.
