Lack of air to the air chambers may result in a "no brake" condition on the affected axle(s).
Remedy: Dealer will inspect and, if necessary, install replacement valves without charge to owner.

Has your Southwest 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.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Southwest dealer can also check your VIN. Recall repairs are free.
