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.

The contact owns a 2020 Land Rover Range Rover Sport. The contact stated that within a week of purchasing the vehicle new, there was an abnormally strong odor coming from the vehicle. The dealer picked up the vehicle and performed an engine cleaning; however, the failure recurred within days. The contact stated that the low coolant warning light was frequently illuminated. The vehicle was taken to the dealer, where the contact was informed that no issue was found. The contact stated that the failure persisted. The vehicle was taken to the dealer, where coolant was added to the vehicle, and the contact had frequently added coolant to the vehicle as needed. The vehicle was taken back to the dealer, where several coolant leaks were found. The vehicle was repaired; however, the failure persisted. The vehicle was taken to Land Rover Charlotte (6710 E Independence Blvd, Charlotte, NC 28212), where it was diagnosed that the inner coolant had leaked into the engine, and there were metal shavings found in the oil. The dealer determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the vehicle was diagnosed after the warranty had expired. The contact related the failure to NHTSA Campaign Number: 23V044000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was notified of the failure and previously offered several vouchers for the repairs. The failure mileage was unknown.

fuel supply line from fuel tank at the engine is leaking on top of the valve cover causing a fire hazzard. The part is not available from the dealership as they said it is on national backorder this line is not damaged in any way and should not be leaking. This needs to be a recall and not the responibility of the customer. The part number from the dealer is LR140080

48V DCDC converter failed leaving car with no power or option to move safety to the side of the road. Part currently backordered due to a high amount of failures.

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.

Due to the poor underbody shielding on these vehicles, the entire hydraulic system (lines, fitting, pumps, etc) of the Active Cornering Enhancement (ACE) system had severely corroded and must be replaced. If this system fails, you lose your air suspension and makes the car unsafe in turning while driving causing you to lose control over your vehicle. My independent service center quote is for $10,000 (which is cheaper than Land Rover ~$15k). There is an active "suspension sensor failure" that does activate in the car, but this can be bypassed by the driver potentially causing more harm while driving. This issue is consistently the #1 or #2 issues with these Range Rover Sports and other Land Rover vehicles. There is no active recall for this major design flaw and there should be.

Carbon fiber hood peeling. This is a safety hazard while driving. This is a common problem among this car. Referenced: LTB01211NAS3 TECHNICAL BULLETIN This was inspected by the manufacturer and they refuse to fix the issue

A safety alert keeps coming up when I attempt to break. Have had multiple services done with ongoing issues with inter cooler parts unheard lines and supercharger so much plastic under the hood investigate and help the consumer it’s a ongoing struggle for customers

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.

A potential concern has been identified on specific vehicles within the above vehicle range. A concern has been identified on Ingenium I4 2.0L Petrol Plug-in Hybrid Electric Vehicle (PHEV) engines where the coolant pump drive belt can become damaged leading to detachment or destruction. Where coolant pump drive is lost, this leads to a loss of coolant flow in the engine. The lack of coolant flow can cause the engine to rapidly overheat, and subsequently ruptures an engine mounted plastic elbow in the cooling circuit. If the coolant elbow is ruptured this leads to a coolant leak onto the turbocharger heatshield which may lead to a fire in the engine compartment which can propagate to the whole vehicle.
