- Summary
- Paccar Incorporated (Paccar) is recalling certain model year 2012-2013 Peterbilt 579 and 587 trucks manufactured February 14, 2011, to December 5, 2012 and 2011 Kenworth T700 trucks manufactured September 21, 2010, to October 1, 2010. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.
- Consequence
- If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.
- Remedy
- PACCAR will notify owners, and dealers will replace the fifth wheel with an Ultra NT model fifth wheel, free of charge. The recall began on December 7, 2015. Owners may contact Kenworth customer service at 1-425-828-5000 or Peterbilt customer service at 1-940-591-4000. Paccar's numbers for this recall are 15KWP (Kenworth) and 1015M (Peterbilt).
- 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.

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.
