2022 Land Rover Defender

While driving on a busy road. My car gave a message saying electrical failure and transmission failure. Within 20 seconds shut the car down before I could safely pull over and it was unable to start. Hazard lights didn’t work and I was stuck in the middle of the road until a tow truck came. The dealer diagnosed the problem as a failure of the dc to dc converter. It has been replaced but took two weeks to repair

On January 25, 2026, while driving my 2022 Land Rover Defender 110 in Colorado on Interstate 70, the vehicle suddenly and completely lost power with no warning. There were no dashboard alerts, warning lights, or messages prior to the failure. The vehicle abruptly became disabled while traveling at highway speed, creating an immediate and serious risk of a crash, severe injury, or death to myself and other motorists. I was extremely fortunate to be able to safely maneuver the vehicle out of traffic and exit the highway. Given traffic conditions on I-70, this failure could easily have resulted in a major accident. The vehicle was undrivable and had to be towed to Flatirons Land Rover in Colorado on January 25, 2026. On January 26, 2026, after I had to repeatedly follow up with the dealership, I was informed that the failure was caused by a defective component related to the battery/electrical system. Although the repair is covered under warranty, the required part is on backorder, and I was advised the vehicle will be out of service for approximately six weeks. The dealership stated they cannot provide a loaner vehicle, leaving me without transportation. They said the dcdc converter and I don not understand and they did not explain well A sudden loss of power without warning at highway speeds represents a serious safety defect that puts drivers and the public at risk. I am concerned this defect may affect other vehicles and could lead to serious injuries or fatalities if not addressed.

I was sitting at a red traffic light, the auto stop/start function activated and engine shut off. when the light turned green I hit the gas and my 2022 Defender stalled. I started the vehicle went to put into gear and it stalled again. I tried to start the Vehicle again and it stalled right away. on my third attempt to start vehicle it finally started. also while driving during the day when i stopped i noticed the auto stop/start indicator would would be white and be in inhibited mode randomly. I had been driving for at about an hour. I had this vehicle for 3 weeks and so far this was the only time it has happened.
