On Sunday, [XXX], in the morning, I was driving my 2022 Land Rover Defender 90 (VIN [XXX], about 33,600 miles) southbound on [XXX] at about 30 mph, with my minor nephew in the car. Multiple warning lights came on and the vehicle shut down while moving, losing drive power. We nearly crashed. The vehicle has not started reliably since. An independent repair shop replaced the alternator and battery and the problem continued; they traced it to an electrical fault draining the 12-volt system and identified the open DC-DC converter recall (the federal safety agency 26V248 / 26V599, Land Rover D126/H575 and E008). My Land Rover dealer (JLR Los Angeles) confirmed in writing that the recall is open on my vehicle but said no remedy exists yet. On [XXX], Land Rover customer service (800‑637‑6837) declined to open a case or commit to any repair, tow, or interim fix. The vehicle cannot be driven safely and I have no remedy available.

What 2022 Land Rover Defender owners say
Most recent owner complaints, unedited.
Nothing has happened yet but my vehicle could stop working at any time due to there not being a fix available. I have been waiting for a fix for six months.
DC/AC error came up once, parked it and turned it off, the error message has not showed up since, i have contacted the San Jose, CA, land Rover dealer, 2 times already, have given them my information and they always say i will get a call back and its been 2 months and i have yet to receive any information on getting these recalls repaired, This vehicle was not cheap and they seem to not care to fix the issue.
This is a serious concern and safety condition. In several occasions while driving at a range from 45-70mph the engine loses power. To the point where it has felt like it will shut off. The inside lighting of the dash dims while the vehicle is in loss of engine power.
My vehicle is losing power from the battery showing battery needs to recharge and its full charged have to turn interior lights off
Alternator & DC/DC Converter failure or DC/DC Converter failure that also led to Alternator failure. I will attach letter correspondence sent to Jaguar Land Rover North America, LLC.
On 4/2/2026, my DC to DC converter failed in my 2022 Landrover Defender (owned 3 months, purchased pre-owned from dealer), which short-circuited both my 12V battery and my telemetric safety battery (location services, and emergency calls). The vehicle lost all power, completely malfunctioned electrically losing ability to accelerate, power steering, and everything went dark in the vehicle while driving on a highway. I immediately tried to get it to the shoulder but it lost momentum and stopped in the lane, with cars and semis coming around a blind corner at speed. It was a harrowing experience, the car started to roll backwards (on a slight incline, as it was a mountain pass) and a semi truck had to assist in stopping the vehicle by skillfully, using his trailer to stop the vehicle. This created body damage to the entire side of my vehicle. The car then locked up completely, wheels were locked and tow truck had to drag it with a chain up on the bed. My son and I could have been killed, as traffic was coming around the bend at 60-65 mph and we were completely stopped and started rolling back towards the oncoming traffic. Several others could have been injured as my vehicle could have cause a major traffic collision. The issue has been reported to Jaguar Landrover customer service, reported to the dealership I bought the vehicle from and to the dealership who told me that it could help to drive the vehicle to charge the battery. The dealer where I towed the vehicle confirmed it was the DC to DC converter failure, confirmed that it fried or short-circuited both batteries which then caused the car to lose all power. The failure was confirmed by certified mechanics, and approved by an inspector for the extended warranty and repairs were made. There was an electrical fault warning on screen. One dealer told me to drive it to charge battery. This vehicle should be recalled to avoid safety issues.
I believe there is an issue with the DC to DC converter. Had an incident when the vehicle was idling for at 30 mins while cleaning snow in driveway after a storm. I received an warning battery low. As thought this was odd I turned it off. waited a few hours returned and the warning was gone. I had JLR dealer look at the issue. I was told the main battery was faulty and replaced, this was in end of DEC 2025. Then weeks later [around Jan 18th 2026] when it was really cold out and driving to JFK airport. while in route i received an very generic electrical system fault warning. As i was leaving 1 of the terminals at JFK. on the exit ramp of the terminal I had complete electrical failure was lucky enough to be able to be able to pull to shoulder, but was coasting about 1-2 mph, and stop. It took 3 attempts to restart the vehicle, when it started normally and all electrical was acting normal. if this happened while on the highway it would have caused an accident and i believe injuries. i will say the hazard warning lights were still working. I have also been noticing that the digital dashboard display brightness will fade in and out anytime of the day and weather randomly. Today this happened and received a low coolant warning and a tire low warning at the same time. I check the coolant level and it is normal. I check the tire pressures and they are normal.
The vehicle lost power after a warning that the battery was not recharging. I have a portable jump start battery. Tried to jump start it -- the battery would not hold a charge once cables disconnected. Had the vehicle towed to the dealer. I was told this is a DC-to-DC converter problem that is widespread across Defenders 20222-present. parts are unavailable.Being stuck in a vehicle with no power, absolutely dead, is scary and would have been a major problem if the electrics had gone out while driving.
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
