NHTSA campaign 25V566, reported August 29, 2025, 1,170 vehicles potentially affected.

What this recall means for you

Certain transit buses have a high-voltage traction battery where a weld on the busbar may be inadequate, and the battery management software may be incorrect. Together, these conditions can cause a battery module to overheat.

An overheating battery module increases the risk of a fire. Vehicle fires can cause serious injury and damage, so affected buses should be repaired promptly.

The repair is free. The manufacturer will inspect and replace the battery module as necessary and update the battery management system software at an authorized dealer. Owners were notified by letter on October 6, 2025, and can call New Flyer customer service at 1-800-241-2947. You can also check your vehicle identification number (VIN) for open recalls.
