- Summary
- On certain trucks, the fifth wheel king pin release air valve internal spool was installed backwards. The air option of the king pin release system would be inoperable. To correct this situation in production, the vehicle's air lines were mistakenly reversed rather than replacing the valve.
- Consequence
- There is a possibility that the king pin can release without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged.
- Remedy
- Dealers will inspect the functionality of the king pin release system and suspect valve. If any vehicles have a non-conforming valve or incorrect plumbing, it will be replaced and re-plumbed. The recall began on February 28, 2007. Owners may contact peterbilt at 940-591-4196.

Has your Peterbilt 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 Peterbilt dealer can also check your VIN. Recall repairs are free.
