Kenworth is recalling 3,841 2018-2024 T800, T660, W900, and T800B trucks because an added spacer in the seat-to-seat-belt tether and buckle joint can leave the connection unsecured.

What's wrong?
The seat assembly in these 2018-2024 Kenworth T800, T660, W900, and T800B trucks includes the seat frame, the seat belt tether, and the buckle connection. That joint is supposed to hold the belt hardware securely to the seat so the restraint stays anchored when the belt is loaded. The seat and belt parts work together, so the joint strength matters as much as the belt webbing itself.
On affected trucks, an extra spacer was added at the joint that connects the seat to the seat belt tether and buckle. PACCAR found that this spacer was installed on certain seat configurations before the joint was verified by a seat pull test. During testing, certain configurations did not pass, and a cracked weld was observed on the seat. The repaired assembly removes the spacer.
There is no warning sign before failure. An owner is not expected to hear, feel, or see the unsecured connection during normal use.

What happens at the repair
At the dealer, a Kenworth technician inspects the seat, tether, and buckle joint for the extra spacer. If that spacer is present, the technician removes it and replaces the bolt needed for the connection. Parts and labor are free under recall 23V717. Owners who paid to fix this seat belt connection before receiving the recall notice can seek reimbursement through PACCAR's general reimbursement plan. Keep repair invoices and payment records, then ask the service desk or PACCAR customer service how to submit them.
