2023 Land Rover Range Rover Sport electrical problems

Filed Mar 28, 2026 · Electrical · VA

The Keyless Vehicle Module security system on my 2023 Range Rover Sport deactivated both of my smart keys simultaneously without any warning or alert. The vehicle locked itself while both keys were inside and completely disabled them both at the same time, leaving my vehicle totally inoperable. I had no way to start or operate my vehicle. There was no warning light, no alert on the dashboard before this happened, and no information provided at purchase that this could ever occur. The only message displayed on the dashboard after the fact was Refer to Handbook Smart Key Deactivated. I am a single father with dependents and this is my only vehicle. I was left completely stranded at my home with no transportation for multiple days. This is a known and documented design defect affecting all Jaguar Land Rover vehicles manufactured from 2022 onwards. The vehicle has been inspected by Land Rover Alexandria dealer located at [XXX] . The dealer confirmed the issue and quoted me $3,000 to replace the Keyless Vehicle Module hardware. After I filed a BBB complaint and contacted Land Rover corporate the price was reduced to $640. My vehicle is a 2023 model and is still under full factory warranty. Land Rover corporate has an open case on this matter under case number XXX No other vehicle manufacturer allows their own security system to completely strand the owner with no warning and no safeguard. This is a serious safety defect because it can strand drivers in dangerous locations at any time without notice INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dash message shown electrical system fault, vehicle shut down completely in less than 30 min. Upon a jumpstart, the vehicle would only run for less than a minute before complete shutdown. Dealership towed vehicle, and states problem with DC converter.

I was driving my vehicle when suddenly I got a "electrical fault has been detected Pull over Safely" error message. At that time the everything is still running and working. I pulled over safely and shut off the car. I restarted it and it said "low battery, start engine". It was really cold and I imagine as the car kept running, that will recharge the battery. I continued to drive (cautiously on local streets) and about 20 mins later, certain electrical features like lane assist and traction control was not available. A few minutes later, more and more systems were being turned off. Eventually, the car's engine died and there was no electric power to the car. I lost steering and brakes. Everything in the car was electronically controlled. The car rolled to a stop but I was not even able to use my hazard lights. Luckily, it was during the day and I was able to roll to a stop and call for help. This is a safety concern if my engine stopped and I was in the middle lane of a highway. I'm unable to steer, brake, or show signs that I'm in trouble to those behind me. The car was eventually towed to a Land Rover dealer and the service rep said I would need my 48V to 12V DC to DC converter replaced. She has at least 10 other vehicles with this issue. The way the car is designed, when the engine is running, it's powering a 48v battery. The 48v battery then converts the electricity to 12v for all the components of the car. In my case, when the engine was running, it was not able to recharge the 12v battery at all. In a vehicle where EVERYTHING is controlled electronically (even the door handles), there should be a failsafe so the 12v battery can be charged when the engine is running but the DC to DC converter doesn't work. This is a serious safety concern if this happened I needed to avoid hitting pedestrians. The horn won't work and I can't roll my window down to yell.

electrical failure of dc to dc converter, confirmed by manufacturer while driving on the highway i got an error message and immediately afterward the entire car shut down. no power steering, no brakes, no lights or hazards, no airbag. i was able to stop the car by gliding into an embankment in the left hand lane of the highway. was towed to the dealership. only by luck was my car not hit from behind or cause an accident behind me as I had no ability to put the hazards on. called 911 several times to assist but they did not come during the two hours i was on the highway. this issue has been reported in other range rover sports 2023 I had a recent full checkup of the car within the last month.

The red light (Electrical Failure) popped up. Next the car essentially shut down - while on the road - luckily it was on a side road so no collision / personal injury occured although it could have been a disaster. After waiting in 10 degree cold, i towed the vehicle to Range Rover and upon testing next day, i was notified that its a defective DC/DC converter. There is no ETA on when the vehicle will be fixed as the part is on back order as this appears to be a systematic failure across a number of Land Rover makes and models. Dealership suggested this should be a wide spread recall. In the meantime, Range Rover knew of this issue. Dindt notify me (or anyone) and put our lives in danger. And have no means to fix the issue given the part is on backorder

The cars electrical system failed while driving on the highway. It first impacted the traction control, then ABS, then put the car into neutral while traveling at 70 mph the highway with no ability to put the car into drive. Fortunately I was able to coast into the breakdown lane before the car completely shut off and put itself in park. Had I not been able to get into the breakdown lane we would have been sitting stalled in the middle of the highway with no flashers p putting me, my wife and kids at significant risk of injury or death with cars and trucks going 70+ mph. The vehicle has been inspected by the dealer and I have been told it is a DC-to-DC converter that has failed and is the cause of the issue. The dealer informed me that this has been a recurring issue for these vehicles and that parts are on backorder due to the volume or orders. At the time of my call they indicated there is a "significant" number of orders nationally for this part. I was fortunate to have been able to get into the breakdown lane but this would have turned out very differently had I not been able to do that. I think others should be warned/aware of this issue.

My vehicle as well received an electric fault message shortly before loosing all electrical power. When I say all I mean all as if someone removed the battery from the car. The issue that was described to me from the service department was the low voltage (12v) to high voltage (48v) I think dc to dc converter shorted out. They said this was the first device after the battery and contained all the battery saftey circuits. It allowed the LiFo battery to reach zero volts and they didn't replace the battery afterwards. When this happened I lost all power steering, lights, ability to use the roadside assistance.

My vehicle lags using the accelerator. If you press the gas it taskes 10 seconds for the vehicle to begin moving unless you give it around 40% accelerator then it jumps uncontrollably forward. This happens everyday. I drive this vehicle constantly and the more I drive it the worse it gets. I feel the electric traction motor doesn't engage because of any number of reasons. I bring it to the shop and they charge the battery. After that it works fine for a few days then begins again.
