What's wrong?
The affected part is the battery pack enclosure on 2021-2023 New Flyer XE40, XE60, and XE35 electric buses. It is the fiberglass housing around the energy storage system, which holds the high-voltage battery equipment and keeps it separated from the rest of the bus. The enclosure is supposed to stay dry inside so the battery system can keep proper electrical isolation.
On these buses, liquid can collect inside one or more battery pack enclosures. New Flyer has not identified the root cause. When liquid is present around high-voltage battery equipment, it can create an isolation fault, which means the electrical system is no longer separated the way it should be. In reported cases, buses had a no-start condition, smoke from a rear battery enclosure, and one thermal runaway event, which is a battery overheating event that feeds on itself.
If the bus is powered on, dash warning lights should indicate a high-voltage isolation fault. That is the warning sign to take seriously before the battery enclosure is inspected.
Who's affected?

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific bus.
What's the safety risk?
Liquid inside the battery pack enclosure can create an electrical short and increase the risk of fire. If dash warning lights show a high-voltage isolation fault, take the bus out of service and call the dealer. If liquid is found, park it outside and away from structures until repaired. Repair will be free at any franchised New Flyer dealer once available.

What happens at the repair
If inspection finds liquid inside a battery pack enclosure, keep the bus out of service and parked outside and away from structures until it is repaired. Once the final dealer repair is available, a New Flyer technician will add four holes and automatic activating drain valves to each battery pack enclosure, free under the recall. Out-of-pocket costs tied to this recall are handled through New Flyer's normal warranty process, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
