- Summary
- PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
- Consequence
- Brakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.
- Remedy
- PACCAR will notify owners, and dealers will modify the air brake system, free of charge. The recall began on January 15, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's recall number is 13KWL.
- Notes
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your Kenworth been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Kenworth dealer can also check your VIN. Recall repairs are free.
