What's wrong?
The BorgWarner (Akasol) Gen3 battery pack on the 2023-2024 Gillig Low Floor is the high-voltage traction battery for the electric propulsion system. It stores electrical energy and sends it to the bus drive system, so the pack and its internal connectors have to stay secure and insulated.
On affected buses, high-voltage connector fastener hardware inside certain battery packs has a quality defect. The fasteners can break, separate from their terminal connection, and become loose debris inside the pack. Loose hardware inside a high-voltage battery pack can create an internal short circuit, which is the failure Gillig and BorgWarner identified for recall 25V203.
There is no warning sign before failure. Gillig reported that it is not aware of an early driver warning that would give enough notice to reduce the risk, so normal operation does not rule out an included bus.
Who's affected?
Covers the Low Floor bus across the 2023 and 2024 model years, with the same high-voltage traction battery component listed for both years.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
A short circuit increases the risk of a fire. If the battery contactors open suddenly, the bus can lose drive power, increasing crash risk. There is no reliable warning sign before this failure, so schedule the repair soon and report any loss of power immediately. Repair is free at any franchised Gillig dealer.

What happens at the repair
At the dealer, a Gillig technician checks the high voltage battery hardware and installs new battery fasteners where needed. The recall repair is free, and parts and labor are covered. Gillig has a general reimbursement plan on file for owners who already paid for a related repair before the recall notice. Keep invoices and repair documentation, then contact Gillig customer service or the service desk to ask how to submit the claim under that plan.
