2024 LAND ROVER DEFENDER Electrical System Problems

The component that failed appears to be the DC-DC converter and/or related charging system within the vehicle’s electrical system, which resulted in complete failure of the 12-volt battery system. The vehicle displayed a dashboard warning stating: “Electrical fault detected. Please find a safe place to stop.” Shortly after this warning appeared, the vehicle lost electrical stability and the 12-volt battery completely discharged. The battery would not hold a charge even after attempted recharging. The vehicle became inoperable and required towing to an authorized Land Rover dealership. The vehicle is currently in the possession of an authorized Land Rover dealer and is available for inspection upon request. It has not yet been repaired. Safety Risk This failure created a significant safety risk because: The warning appeared while the vehicle was being driven. The electrical system is critical to power steering, braking assist, stability systems, lighting, and other safety components. A sudden...

Car has had 2 separate, distinct failures of the DC/DC converter which result in electrical faults rendering all systems unusable (gearbox, steering, etc.) and making the care immobile. I have had it replaced once in September 2025 following a failure, and then the replacement failed in January 2026. This is incredibly dangerous while driving. Dealer and Land Rover are aware of widespread failures, parts are backordered with no timeline. Warning light starts with 'Electric Fault Detected' and continues to function for an indeterminate amount of time before failing completely.

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...

Yes, my car caught fire. It's at an impound currently. My clothes caught fire when I tried putting it out. The car could have been parked in my garage or been in NYC, with a full tank of gas, that would have caused serious damage. My insurance company is sending an investigator to look into it today. No, warning lamps, messages or symptoms.

Turned the car on and the display screen was black and would not work. This is after we did the software update several months ago.

Near dusk, the driver display (speedometer, tachometer, fuel gauge , etc.) automatically dimes to night mode and becomes unreadable. Turning the rheostat controlling display brightness does nothing. Very dangerous. Display should only go to night mode when conditions are actually dark.

We were driving at highway speeds on paved, dry road. The vehicle threw a electrical fault error. As I drove to a safe location to pull over, the vehicle switched into Neutral, every warning light on the dash lit up and my power steering failed. We barely coasted to a safe spot on the shoulder of the highway we were on in the mountains. The parking brake also would not work. The vehicle then completely died and we were stuck in an area with no cell phone service. The rear hatch also would not open
