SEAT BELTS
Defect Description
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.
Consequence
An unsecured seat belt connection may not properly restrain an occupant during a crash, increasing their risk of injury.
Remedy
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.
