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.
What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle appears to have experienced a failure or malfunction involving the electrical power system, charging system, 12 volt battery system, vehicle communication modules, or related components. Based on the recent Land Rover recall I found online, I am concerned that the DC to DC converter or related charging system may be involved, because the reported recall issue involves loss of 12 volt charging and potential loss of drive power. The vehicle is currently with Jaguar Land Rover Houston Ce
While driving my 2024 Land Rover Defender 130 on Route 114 in Massachusetts at approximately 8:30–9:00 PM in dark and rainy conditions, the vehicle suddenly and completely shut off while in motion. The vehicle lost all power: • Engine shut off • No gears functioned • Vehicle would not restart • Lights and hazard lights were not functioning The vehicle was stranded in the middle of an active roadway with no warning and no visibility. Because of this, I had to exit the vehicle into traffic, stop oncoming vehicles, and remove my child from the car. We crossed a live
While operating the vehicle within normal constraints, at or below the speed limit, a electrical fault warning alterted me to multiple issues. Begining with ABS failure warnings, and adaptable cruise failure the vehicle continued for the next 30 minutes to show multiple system failures. Finally the vehicle lost complete power in the middle of a street with the brakes locking and no ability to steer. Attempts to jumpstart the vehicle failed to remedy the situation. When the vehicle was taken to the dealer the problem was diagnosed to be a failure of the DC/DC converter.
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 v
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 a
