2020 Land Rover Range Rover Sport electrical problems

Filed Nov 4, 2026 · Electrical · NY

I am submitting this complaint regarding our Range Rover Sport HSE P400 due to ongoing mechanical issues and the unacceptable service experience we have encountered with Land Rover. We have brought our vehicle to the dealership approximately six times for the same recurring issue. The vehicle repeatedly displays battery warning lights, experiences starting issues, and ultimately will not start. Despite multiple visits and attempts to resolve the problem, Land Rover has yet to identify and permanently correct the underlying issue. Throughout these visits, we have been given different explanations and advised to pay for or address different repairs, including: Replacing the battery. Repairing a leaking pipe. Being informed that oil particles were found and that the oil filter had not been changed. Most recently, being told that the starter may be the cause of the problem. We have continued to cooperate with the dealership, follow its recommendations, and bring the vehicle back whenever the same issue occurs. However, after six visits, we are still dealing with the same problem. It is extremely concerning that a vehicle requiring repeated service for the same symptoms has not received a definitive diagnosis or a lasting repair. What makes this situation even more frustrating is the dealership's refusal to provide us with a courtesy vehicle. We were told that because we did not originally purchase the vehicle from their dealership, and because we have supposedly exhausted the available discounts, we would need to arrange and pay for our own rental vehicle. We find this reasoning unacceptable. We are bringing a Land Rover vehicle to an authorized Land Rover dealership for repairs, not requesting a personal favor. The fact that we purchased the vehicle elsewhere should not determine whether we receive reasonable assistance while our vehicle is repeatedly being serviced for unresolved mechanical problems. Furthermore, we should not be financially penalized or lef

My vehicle started showing a battery high voltage error light and was coming on and off at random times while driving. I reported this to the JLR dealership and they scheduled an appointment to have it serviced. Even though the vehicle was showing signs of battery issues which was an active known recall, they never checked it or mentioned it. They advised that I needed a main battery which cost me almost $1,000. As soon as I cranked the vehicle to leave, the light came on again. I went back inside to advise that it wasn’t the main battery because the light is still on. They advised that their loaner fleet was low and said it was safe to drive. They were going to schedule a second service the following week. I emailed them the next morning to advise that I was traveling for work at the end of the week and did not feel safe driving that vehicle. They called me right after to advise that I should not worry, it was probably the BMS reset and it was in fact safe to drive. I left that Sunday headed out of town. One and half hours into the drive the car first threw an electrical fault detection warning. I was driving over 70 mph on a major highway in heavy traffic. Shortly after several other lights came on one after the other. electrical then ABS ,traction , etc. The vehicle then completely lost power and by the grace of god I was able to limp over to a shoulder of the highway in a curve. I had no lights or power to the vehicle. I immediately called [XXX] to assist before I was run over by another vehicle. They had to standby with lights for over an hour waiting for a tow truck. The service center is now telling me that corporate refuses to fix the recall for the DCDC converter and that the problem is the second battery. They will not fix the recall even though they have the microchip to fix it per the service department but they are saving them for the cars that actually breakdown! They are now asking me to pay an additional 3000 to replace the swing battery. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMAT

The braking system keeps repeatedly failing. I have numerous times been driving when the braking system locks, leaving the car uncapable of securing a safe stop at any given moment. In 2024, the vehicle was serviced at Landrover Englewood, NJ where I paid for repairs. The same problem yet again emerged causing the risk of potential accident on September 1, 2026 while driving on the local city roadways. The following dashboard error messages came on my screen: "Hill Descent Control not available", "OK to drive with caution Stability control not available," and there was a third (?) message that I did not capture in time. These signs have intermittently popped up on my dash over the past few years and when brought to Mt. Kisco (seller) dealerships attention, was told by the service manager at the time that this was not an issue to be concerned with. The vehicle is currently in the landrover Edison NJ shop again due to the SAME BRAKE FAILURE/ISSUE I EXPERIENCED IN 2024, but yes, is available for inspection upon request. I launched an email back in 2024 (copy is available at your request) regarding this same issue to the landrover dealer and attorney generals office highlighting the safety risk, as I was traveling on the turnpike (the most concerning, heart dropping, life threatening experience) amongst other public roadways when I experienced this life threatening safety concern. I had to think immediately and shift the vehicle into park mode while driving because the vehicles brakes locked and failed to stop the vehicle. The vehicle was eventually fully inspected by the Mt. Kisco landrover service center and returned back to me, deemed safe in 2024. No other inspections from any other parties, to my knowledge, have been made.

I was driving my vehicle on a California freeway and it stopped at traffic signal that was red. When the light turned green and my vehicle accelerated forward the vehicle system powered down in the middle of traffic. I had the vehicle towed to a local mechanic who identified two potential causes for my vehicle powering down and one of the items referenced was the recalled dc converter. I had the vehicle towed to my local Land Rover dealership and they confirmed that a faulty dc converter was the cause. Land Rover is asking for me to purchase a new dc converter at a cost of $3,000 that is currently under recall and they are unwilling to wave the cost of the repair leaving the vehicle inoperable. I asked the Land Rover dealership to give me a quote to purchase the inoperable vehicle from me and the offered a wholesale price acknowledging that they are unwilling to pay market value because of the recall with no remedy but when a remedy is found they might be willing to purchase at current market value. I suspect the dealerships motive is to purchase my car at a wholesale price, replace the recalled part with another recalled part and sell at a outsized profit will leaving me underwater with a lender.

The DC/DC converter went out. While driving [XXX], all the warning lights came on, no abs, no front collision warning and all other safety warnings lights flashed. Immediately after the lights came on vehicle completely shut down while driving leaving me stranded in the street in Greenwood, AR. I had my vehicle towed to the dealership. Land Rover was already aware of the DC/DC converter issue but told me it was the battery which I paid to have replaced. I drove my vehicle home from the dealership. After arriving home my vehicle would not lock. I contacted the dealership and was advised to bring it back in when they had an appt in 3 weeks. I could not drive my vehicle due to not being able to lock it. While driving the vehicle to the dealership to get repaired because it would not lock, my vehicle shut down this time leaving me stuck in a blind spot on a rural highway (55mph speed limit) with no where to pull over due to deep drainage ditches on the shoulder. For two hours I had to wave at vehicles letting them know there was a dangerous hazard in the road (my vehicle) while waiting for the tow truck. My vehicle was again towed to the dealership, 126 miles away. It was at this time I was advised by the service advisor later confirmed by the General Manager, Land Rover had an ongoing problem with the DC/DC converters. My vehicle has been at the dealership since February 9, 2025 because they do not have the DC/DC converter available. The dealership does not provide loaner vehicles. I have since researched the internet and found numerous articles and other complaints regarding the DC/DC converters going out in Land Rover vehicles.

While traveling at highway speeds, the vehicle suffered a sudden and total loss of motive power (high-speed stall) without prior symptoms. A "Charging System Fault" message appeared seconds before the engine and all critical electrical systems shut down. This failure occurred in active traffic, resulting in the immediate loss of power steering and electronic braking assistance, creating an imminent collision risk for the occupants and surrounding motorists. Component Failure: The authorized dealer confirmed the failure of the DC-DC Converter (original part LR176476), which regulates the 48V-to-12V charging cycle. The component is currently held by the dealer and available for inspection. The failure caused a secondary total depletion of the 12V battery, rendering the vehicle's safety lighting and hazard signals inoperable. Manufacturer Awareness: The dealer confirmed the original part has been discontinued and superseded by a revised design (Part 433123472) due to known defects. Furthermore, the dealer stated that multiple other vehicles are currently grounded at their location awaiting the same backordered safety component. There is currently no estimated time of arrival for the revised part, leaving the vehicle indefinitely sidelined due to a systemic manufacturing flaw.
