2023 Land Rover Range Rover Sport Engine Problems

VEHICLE: 2023 Land Rover Range Rover Sport HSE, Original owner since February 2023. NATURE OF DEFECT: Persistent and unresolved coolant loss from the engine cooling system, with evidence suggesting leaked coolant is contacting hot engine components and creating a potential fire hazard. CHRONOLOGY: Beginning in February 2026, the vehicle began displaying recurring "low coolant" warnings on the instrument cluster. The vehicle has been presented to an authorized Jaguar Land Rover dealership three times for warranty diagnosis and repair of this complaint. On each of the three visits, the dealership replaced a single cooling system component (a hose or O-ring). After each repair, the low coolant warning returned within approximately two weeks. The most recent repair, completed on May 26 2026, involved replacement of an O-ring on a lower coolant hose that had been previously serviced under JLR safety recall N785. The vehicle was returned to me on Thursday, May 28 2026. On Tuesday afternoon, June 2 2026 (approximately five days after the most recent repair), I detected a distinct burning odor from the engine compartment while the vehicle was operating. On Wednesday morning, June 3 2026, I visually inspected the coolant expansion tank and confirmed the coolant level had again dropped below the minimum mark. SAFETY CONCERN: The combination of recurring coolant loss and a burning odor originating from the engine compartment is consistent with coolant contacting hot engine components — most likely the turbocharger, exhaust manifold, or associated heat shielding. This is the same failure mode that prompted JLR safety recall N785 (NHTSA Campaign 23V-221) on 2019-2022 Range Rover Sport PHEV vehicles, in which leaking coolant onto the turbocharger heat shield was identified by the manufacturer as creating an increased risk of fire. My 2023 Range Rover Sport HSE is not currently included within the scope of recall N785

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.

Since buying this car brand new it’s been nothing but problem after problem. Newest problem is one I’ve been researching and long history of this issue. Needs to be recalled. It’s a DcDc issue very well known parts are on lengthy back order and the cost is astronomical!!! Please help !!!

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.

The car had a warning light in December “stop safely electrical fault detected” Land Rover dealership told me nothing was wrong, except I don’t drive enough & the battery was low. Eventually, the warning went away. This week, the warning light was back, along with additional warnings. The car literally shut down & quit working while it was running. I was sitting in a drive-through. I could not put it in park or drive. Extremely dangerous!!! I had to tow it to the dealership. Again we were told that I don’t drive the car enough. i’ve had it for 5 months and it only has 3000 miles. We refused to accept that as an answer. Eventually, they said there was an update needed. I still do not feel this car is safe.
