- Summary
- On certain trucks, an RA529 king pin release air valve was manufactured with the internal spool installed backwards. This results in the air option of the king pin release system being inoperable. To correct this situation, the vehicle's air lines were reversed rather than replacing the valve.
- Consequence
- With the lines reversed, the king pin can be released without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
- Remedy
- Kenworth will inspect the king pin release system and suspect valve. If any vehicles have a nonconforming valve or incorrect plumbing, it will be replaced and re-plumbed. The recall began on November 29, 2006. Owners may contact kenworth at 1-425-828-5440.

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.
