Summary
Navistar, Inc. (Navistar) is recalling certain 2021-2024 IC Bus RE, 2022-2024 IC Bus CE, and IC Bus EV school buses.

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 IC Bus 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 IC Bus dealer can also check your VIN. Recall repairs are free.
