20215212021-08-20. Brakes. Issue: On certain trucks, the Hill Start Assist valve assembly could be damaged by contact with the rear axle. If this happens, there could be reduced braking or a loss of rear brakes. Safety Risk: Reduced braking or a loss of rear brakes can cause extended stopping distances and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to inspect the clearance between the Hill Start Assist valve assembly and the rear axle. The dealer will rework the assembly if more clearance is needed.

A campaign lists a year, a make and a model, and often only some of the vehicles built. A list with nothing on it is not a clearance either. The lookups below check one VIN.
