2020 Land Rover Range Rover Sport

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 contact owns a 2020 Land Rover Range Rover Sport. The contact received notification of NHTSA Campaign Number: 26V248000 (Electrical System); however, the part to do the recall repair was not yet available. The local dealer was contacted, and it was determined that the battery needed to be replaced. The battery was replaced but the failure persisted. No additional repairs were performed. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that the automatic start-stop system became inoperable. The contact associated the failure with the recall. The approximate failure mileage was 54,000.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The component that failed is the charging system alternator on my 2020 Range Rover Sport HST (mild-hybrid). This vehicle has experienced three alternator failures prior to 100,000 miles. The failed alternator and related components are currently in dealer possession and are available for inspection upon request. Failure of the alternator creates a safety risk because loss of charging capability can lead to battery depletion, electrical system shutdown, warning system failure, reduced vehicle functionality, or potential loss of power while driving. Electrical warnings and system faults increase driver distraction and may impair safe operation of the vehicle. The problem has been confirmed and reproduced by an authorized Land Rover dealership, which diagnosed the most recent alternator failure promptly. All maintenance and repairs have been performed exclusively at authorized Land Rover dealerships, with no evidence of owner neglect or misuse. The vehicle is subject to a Battery Energy Control Module (BECM) recall and related charging system software actions, which affect voltage regulation and the charging architecture that supports alternator operation. The vehicle and charging system have been inspected by the manufacturer’s authorized dealer on multiple occasions. Prior to failure, the vehicle displayed charging system warnings, battery-related messages, and electrical fault notifications. These symptoms appeared before each alternator failure and prompted service visits. Over the past two years, the vehicle has been out of service for approximately 178 days due to repeated electrical and charging-related issues. Given the repeated alternator failures, recall-related charging system involvement, and safety implications of charging loss, this appears to be a systemic electrical defect rather than an isolated incident.

Faulty code P0A7B and P0A1F for the Battery Energy Control Module BECM was diagnosed. Check engine light appeared and then car shut off at a light when attempting to press accelerator. Was told by dealer the part needed replacement instead of just a software update. A recall was shown in general for my year and type but not specifically for my vehicle. My vehicle should be included with this recall to replace the component.

I am reporting a significant safety issue related to my 2020 Land Rover Range Rover Sport involving sunroof water intrusion that has caused serious electrical failures throughout the vehicle. Shortly after owning the vehicle, I began to notice water leaking from the sunroof area, which has now caused malfunctions in the electrical system. These include: •Unresponsive or erratic infotainment and dashboard displays •Malfunctioning electronic safety features •Water pooling near or inside the footwell •Warning lights and errors on the instrument panel •Intermittent failure of lights, power seats, and other electronic systems This defect poses a safety hazard because electrical components exposed to water may fail while the vehicle is in operation, possibly leading to loss of vehicle control, disabled safety systems (e.g., airbags or brakes), or electrical shorts that could result in a fire. Upon researching, I discovered that this is a known issue in multiple Land Rover and Range Rover models, including Technical Service Bulletins (TSBs) issued in prior years. It appears to stem from poor drainage design or faulty sunroof seals, and the location of sensitive electronic modules beneath areas prone to leaks. I am requesting that the NHTSA investigate this issue to determine whether it qualifies for a recall, and to ensure Land Rover is held accountable for resolving what appears to be a widespread and dangerous design flaw. Please contact me for additional documentation, photos, or repair records. I am currently working with a dealership, and I may pursue action under New Jersey’s Lemon Law if this is not resolved.

I took my Range Rover in for a coolant leak, was told there was a Recall on a battery system, the recall was a software update to prevent that battery system from going offline. The system was already offline, and Land Rover North America refuses to honor the intent of the recall, and is refusing to cover the cost to replace that battery system. It only seems logical that if a recall is to prevent an issue from occurring yet the issue has already occurred, they should cover the cost to fix it. Notes form dealer below: RECALL - PERFORM OPEN RECALL # Labor $0.00 1. Unable to perform recall # N861 at this time due to BECM being off line. BECM requires replacement beforerecall can be performed.
