Summary: Certain commercial series transit buses equipped with cummins isb-02 diesel engines built with emc controlled fuel lift pumps. Erratic voltage supply to the fuel lift pump causes premature electric brush wear internal to the fuel lift pump. This premature wear could result in fuel lift pump failure and in some cases may cause an engine stall condition.
Consequence: Should the engine stall, a vehicle crash could occur.
Remedy: Cummins, in conjunction with blue bird, will notify owners and repair the engines by emc recalibration and replacement of the fuel lift pump at no charge to the customer. Owners may contact cummins assistance center at 1-800-diesels or blue bird at 1-478-822-2242.

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.
