2020 Land Rover Range Rover Sport Electrical System Problems

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 Manufacturer Awareness: The dealer confirmed the original part has been discontinued and superseded by a revised design (Part 433123472) due to known defects.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.

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.

Hill decent control error, stability control not available error, and charging system fault detected error while driving. As a result, no breaks while driving.

HIT A CAR THAT PULLED OUT IN FRONT OF ME AT ABOUT 20MPH AND THE AIRBAGS DID NOT DEPLOY AND THE SOS BUTTON DID NOT ACTIVATE. THEN I PUSHED IT MANUALLY AND IT FAILED TO MAKE A CALL UNTIL 20 MINS LATER AFTER THE POLICE ARRIVED. VEHICLE WAS IN MOTION IN THE CITY WHEN LOOKING AT SOME OTHER RANGE ROVERS AT THE COLLISION CENTER IT SEEMED LIKE THE AIRBAGS WERE NOT AS SENSITIVE AS THEY SHOULD BE.

I HAVE HAD OVER 8 INSTANCES WITH EITHER THE LOWER SCREEN, UPPER SCREEN OR BOTH SCREENS COMPLETELY BLACKING OUT AND BEING INOPERABLE. LANDROVER HAS HAD 4 ATTEMPTS TO FIX IT UNSUCCESSFULLY WITH LANDROVER CORPORATE INVOLVED. IN ADDITION, THE SIDE VIEW MIRRORS DIP DOWN IN REVERSE AND DID NOT CORRECTLY RESET THEIR POSITION ONCE IN DRIVE SO I HAD ZERO VISIBILITY IN DRIVE IN EITHER SIDE VIEW MIRRORS. THE SCREEN ISSUES HAS OCCURRED ON CITY STREETS AND ON THE HIGHWAY. THE SIDE VIEW MIRRORS OCCURRED ON CITY STREETS. IN ADDITION I LOSE ALL CONTROL WHEN THE SCREENS BLACK OUT TO CONTROL THE CLIMATE, THERMOSTAT TEMPERATURE, DRIVER MODES, ROCK CRAWL MODE, AND MORE. I SENT LAND ROVER CORP OVER 2 DOZEN PICTURES AND VIDEOS DOCUMENTING EACH TIME IT OCCURRED. THE FIRST ISSUE HAPPENED IN JANUARY 3 WEEKS AFTER BUYING THE CAR AND THEY'VE CONTINUED THROUGHOUT FEBRUARY AND NOW ARE STILL CONTINUING INTO MARCH. I FILED A COMPLAINT WITH CORPORATE ASKING FOR A CORPORATE BY BACK UNDER THE LEMON LAW WHICH WAS DENIED. I PAID 97,000 FOR THIS VEHICLE AND THE ONLY THING THEY OFFERED WAS ONE MONTHS FREE FINANCE PAYMENT OF $993. THE CAR IS NOT SAFE TO DRIVE!
