What's wrong?
The high voltage battery pack on the 2025 Oshkosh Ngdv Electric stores the energy that moves the vehicle. Inside that pack, a contactor works like a heavy duty electrical switch. It closes to let high voltage power flow to the propulsion system and opens to shut that power off when the system commands it.
On affected vehicles, the contactor coil terminal inside certain battery packs has a manufacturing defect. In extreme cold, that defect can let the contactor open while power is under load. When the switch opens at the wrong time, the propulsion system loses battery power and the vehicle loses drive power.
There is no warning sign before failure. Once the condition occurs, the vehicle can show diagnostic fault messages and become unable to restart or propel itself. That means the first thing the operator notices is the loss of propulsion, not an earlier warning light or change in how the vehicle drives.
