Summary
Paccar is recalling certain model year 2011 kenworth T700 vehicles equipped with fontaine ultra lt model fifth wheel manufactured from October 5, 2010, through October 13, 2010. During the trailer coupling process, it is possible for a driver to partially close the fontaine ultra lt model fifth wheel around the trailer kingpin without the fifth wheel being fully engaged and locked.
Consequence
A partially coupled fifth wheel may result in a trailer unexpectedly separating from the tractor, increasing the risk of a crash.
Remedy
Repairs have been completed to all affected chassis by the equipment supplier, fontaine. Accordingly, an owner notification campaign is unnecessary and is not planned. Owners may contact kenworth at 1-425-828-5440.
Notes

Vehicles covered

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.
