Land Rover Range Rover Sport won't start 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

2020 Land Rover Range Rover Sport VIN: [XXX] Repair Order/Invoice No.: XXX the federal safety agency Recall No.: 26V248 Land Rover Recall No.: D126/H575 I received a Land Rover safety-recall notification in June 2026 concerning the DC/DC converter on my vehicle. The recall is identified by the federal safety agency as 26V248 and by Land Rover as D126/H575. The subsequent failure of my vehicle involved the exact component identified in the recall. On or about XXX, my vehicle experienced a charging-system fault and would not start. I brought the vehicle to Jaguar Land Rover Van Nuys/[XXX]. The dealer's own repair documentation states: "DC / DC converter internal failure." The dealer further documented that the charging system was producing approximately 11 volts. The dealer then: Removed/replaced the DC/DC converter. My vehicle subsequently experienced the exact condition described in the recall, and the dealer diagnosed the exact recalled component as having an internal failure. I was charged $2522.59 for the repairs of the DC/DC converter and battery replacement due to low voltage. the federal safety agency states that recall repairs are to be performed free of charge at the manufacturer's dealership. I was informed that I needed a second letter of notification for reimbursement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Component/System: 48V Mild Hybrid Electric Vehicle (MHEV) system including the DC/DC Converter (subject of active recall D126), Battery Energy Control Module (BECM), Telematics Control Unit (TCU), Battery Charge Control Module (BCCM), and Vehicle Immobilizer Module (VIM). All components are available for inspection upon request. What happened: My 2021 Range Rover Sport HSE MHEV (VIN: [XXX] ) experienced a complete no-start condition after sitting for approximately one week. Prior to towing the vehicle to Hendrick Jaguar Land Rover Charlotte, I performed a live data diagnostic using a Land Rover specific iCarsoft LR V3 diagnostic tool which confirmed the 48V hybrid battery at 17.86% state of charge critically below the minimum threshold required to authorize a start sequence. The TCU, BCCM, and VIM all showed not fitted simultaneously a known cascade effect of a critically depleted 48V MHEV system. Recall D126 for DC/DC Converter failure was confirmed on my vehicle. The DC/DC converter manages power transfer between the 48V and 12V systems. Its failure directly caused the 48V battery depletion and subsequent cascade module failures. Safety risk: The vehicle became completely immobile with no warning. The immobilizer went offline preventing the vehicle from starting, stranding the occupant in a parking lot. A vehicle that shuts down without warning and cannot be restarted poses a serious safety risk to the driver and other road users. Additionally the DC/DC converter failure affecting the MHEV system represents a risk of sudden loss of hybrid assist during driving.

FIRST ISSUE-THIS REPORT - LOSS OF POWER / ELECTRICAL FAULT (4/10/26) On April 10, 2026, I backed out of a parking space into a drive lane in a commercial parking lot. As the vehicle was rolling, it suddenly lost power. I attempted to restart the vehicle, but it would not start. The vehicle continued rolling backward into the intersection. Two warning messages appeared on the dashboard -"Stop Safely/Electrical Fault Detected" "Stop Safely – Loss of Drive".Photos attached. Because the vehicle could not be restarted or moved, it remained disabled in the intersection for approx two hours. The vehicle had to be towed to the dealership. When the vehicle was taken to the dealership, I was later told that no problem could be found. The dealership reportedly ran a computer diagnostic test & stated that nothing was wrong with the vehicle. They performed routine maintenance, charged more than $900, & returned the vehicle to me without identifying or repairing the cause of the loss-of-power event. SECOND ISSUE – INTERMITTENT SENSOR FAILURES - The vehicle's front & rear sensors operate intermittently. I scheduled a service appointment for May 20, 2026, to address this issue, but I was forced to cancel a I did not have transportation available. THIRD ISSUE (reported to BRAKE SLAMING/SUDDEN STOP (5/2/26) On 5/2/26, the vehicle experienced a brake slamming/sudden stop while I was driving through an intersection. Following this incident, I developed neck pain & headaches. The vehicle was towed to the dealership for a second time. During discussion with the dealership, I was informed that the April 10, 2026 service visit had been documented as relating to a "check engine" light. I want to make clear that the warning messages displayed during the April 10 incident were not a check-engine light. The messages displayed were: • "Stop Safely–Electrical Fault Detected"• "Stop Safely–Loss of Drive" My research found reports of other RR owners experiencing the same issue.

Won't start & battery drain

While driving home on the evening of June 27, 2023, a distance of about 15 miles, the low coolant light suddenly came on, and as we tried pulling over on the next freeway exit, the engine appeared to seize and cut out. It was difficult to brake and steer the car and we were nervous to get in an accident. We came to a rest off the freeway and then officers helped us push our car into a nearby Auto Zone. We left it there overnight to rest and when we came back the next day, the engine would not start. Had it towed to a nearby independent service center where they determined both engine heads had blown. The car is available for inspection. I have called the manufacturer to see if there were any recalls related to this and found a P055 recall for this model. The description in this recall is very similar to what we experienced.

When the vehicle is parked. The vehicle consistently does not recognize the key fob. The vehicle doors will not unlock when touching the door handles, the car does not start when trying to use push to start. Gives an error message that the key is not recognized. This is a safety issue because it is unsafe to have a vehicle that cannot be started thereby stranding myself and my family during the cold winter months.
