What's wrong?
The high voltage battery pack on the 2025 Bollinger Motors B4 stores the electrical energy that powers the truck's propulsion system. Each affected truck uses two packs, and each pack depends on a sealed top cover to keep water and other liquid away from the high voltage components inside.
On the recalled trucks, a fastener in the battery pack top cover was not installed correctly. During production at a new assembly facility, the torque control for those cover fasteners was not tight enough to confirm every fastener was fully seated. When a fastener is not seated, the sealing washer does not press against the mating surface as designed. That leaves a leak path into the pack, and liquid intrusion risks compromising electrical isolation around the high voltage bus.
The warning sign is an isolation fault from the Battery Management System. The truck receives a diagnostic trouble code, or DTC, when the system detects that isolation fault.

What's the safety risk?
Liquid intrusion into the battery pack can cause electrical isolation loss or a short circuit, raising the risk of fire or shock. A detected battery fault can also cut drive power and raise crash risk. If the vehicle reports a battery fault, drive cautiously and arrange service soon. Repair is free at any franchised Bollinger Motors dealer.

What happens at the repair
At the dealer, a Bollinger Motors technician works with Our Next Energy to inspect the high voltage battery pack sealing and repair the battery packs that need work. The inspection and repair are free under the recall, with parts and labor covered. Bollinger Motors is not offering reimbursement for this campaign because the remedy is being applied before any vehicle is delivered to dealers.
