What's wrong:
PACCAR Incorporated (PACCAR) is recalling certain 2027 Peterbilt and Kenworth vehicles. Please see the recall report for a complete list of models.

Risk:

What to do:
Dealers will inspect the PDC serial numbers, and replace the PDC boxes as necessary, free of charge. Interim letters notifying owners of the safety risk are expected to be mailed September 25, 2026. Additional letters will be sent once the final remedy is available. Owners may contact Peterbilt's customer service at 1-940-591-4220 and Kenworth's customer service at 1-425-828-5888.
