What's wrong?
The sub-junction box in the 2025 Isuzu Nrr EV is part of the high-voltage electrical path that feeds power to the electric drive motor. Inside that box, a bus bar acts like a solid metal conductor, carrying current across the connection terminal so the motor and inverter receive steady power.
On affected trucks, the sub-junction box was designed with a 1.5mm gap between the connector and the bus bar. That gap lets the fastening bolt loosen at the terminal. A loose connection raises electrical resistance, which creates heat at the connection point. If the system overheats, the EV control system shuts off current to the drive motor, and the truck loses propulsion.
The warning sign is electronic, not mechanical. The driver display can show a warning light and malfunction message tied to an EV system fault, then current to the drive motor shuts off.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A loss of drive power increases the risk of a crash. When one of the listed diagnostic codes sets, a warning appears and power to the EV drive motor shuts off. If the warning appears or drive power drops, move out of traffic and contact an Isuzu dealer. Repair is free at any franchised Isuzu dealer.
What should I do?
- Check your VIN to confirm your 2025 Isuzu Nrr EV is included in this recall.
- Contact a franchised Isuzu dealer to schedule the free sub-junction-box replacement and inspection that addresses overheating and drive-motor shutdown.
- Bring the recall notice if Isuzu mailed one. If not, reference recall number 25V319 when you call.
- Drive cautiously until the repair is complete. Pull over safely if the vehicle loses drive power.
What happens at the repair
At the dealer, an Isuzu technician replaces the sub-junction box. The technician also inspects the wiring harness and motor/inverter and replaces those parts if the inspection shows damage or overheating. Parts and labor are covered, and the recall repair is free at the dealer now. Isuzu does not offer a separate reimbursement program because all affected vehicles are still under the new vehicle warranty. If you already paid for related work, ask the service desk how the warranty applies to that paperwork.
