NHTSA Complaint #11714834 — 2024 LAND ROVER DEFENDER

Repeated failures of the 48v to 12v DC to DC converter. Failure to charge the 12v system results in an complete drain of the 12v battery in under 30 mins while operating the vehicle. The result is an immediate shut down of the vehicle. In my case, while in the middle of a travel lane. Without 12v power the vehicle cannot be shifted into neutral and cannot be moved creating a very unsafe situation. My vehicle has been in an authorized land rover service dealership five time on this issue. The converter was replaced only to occur again. The vehicle displays and warning message on the dash that an electrical failure has occurred and to stop the vehicle. As the voltage of the 12v battery drops, multiple systems begin to fail in fast progression while trying to get to a safe pullover. Multiple engine fault codes occur, including electrical generator failure. Current mileage on the vehicle 13800.
