12 recalls found in NHTSA data as of September 22, 2026

For the 2021 Gillig LOW Floor. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

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