Consequence: Loss of air pressure could result in longer stopping distances which could result in a crash.
Remedy: Dealers will add the required check valve to the front air brake service reservoir to insure compliance with FMVSS no. 121. The recall began on July 30, 2004. Owners should contact blue bird at 478-822-2242.

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