Front Steering Knuckle Fractures
The Office of Defects Investigation (ODI) is upgrading its Preliminary Evaluation (PE25006) of front steering knuckle fractures on model year (MY) 2014 through 2017 Range Rover Sport vehicles to an Engineering Analysis. ODI opened PE25006 on June 27, 2025, after receiving 12 Vehicle Owner's Questionnaire (VOQ) reports of the front aluminum steering knuckles fracturing in these vehicles. The reports describe the fractures occurring at the joint where the steering knuckle attaches to the upper control arm ball joint in one or both steering knuckles. Fracture of the front suspension knuckle can lead to detachment of the upper suspension arm. Detachment of the upper suspension arm results in the driver’s inability to control the vehicle, increasing the risk of a crash. ODI reviewed information supplied by Jaguar Land Rover (JLR) in response to Information Request letters as well as reviewed the data with JLR on numerous occasions. ODI further reviewed relevant data on a peer vehicle with a significantly similar steering knuckle design, the MY 2014 through 2017 Range Rover. Much of the information is contradictory and requires a deeper analysis that is available in an Engineering Analysis. On August 5, 2025, Jaguar Land Rover (JLR) filed safety recall 25V514. This recall covers certain MY 2014 and all MY 2015-2017 Range Rover and Range Rover Sport vehicles. The remedy for recall 25V514 addresses knuckles with and without a visible fracture. Knuckles that have developed a visible fracture will be replaced with a new knuckle of a substantially similar design. Knuckles with no fracture visibly present will have a brace attached to the upper portion of the front steering knuckle. JLR states that the purpose of the brace is to prevent the component from completely separating should a fracture develop. NHTSA continues to receive allegations of fractures occurring in the front steering knuckles of Range Rover and Range Rover Sport vehicles. Two of the most recent VOQs received by ODI involve front steering knuckle fractures occurring on MY 2020 and MY 2021 Range Rover L405 vehicles. ODI will continue to investigate the component design and assess the potential safety risk as part of this Engineering Analysis and evaluate the recall remedies for Recall 25V514. Further, the scope of this Engineering Analysis will be expanded to include MY 2018-2022 Range Rover and Range Rover Sport vehicles as they have a substantially similar component design.

Reports submitted to NHTSA, shown in the owner's own words
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.

We recently bought this vehicle a few weeks ago. Since we’ve had it I have been noticing a strong smell of burning engine coolant. I have looked at similar models of the 2021 Range Rover sports and they do have recalls for issues with the engine coolant system. I assume this is the same problem the phev Range Rover sport is having. Today I have a low engine coolant message pop up on the dash.

I took my car in for an oil change, and they noticed a faint fuel smell (Which I had noticed as well). I had them look deeper and the found a small fuel leak, requiring Part LR140080 to repair. This part is worldwide back ordered from Land Rover. When I ordered at the Range Rover dealership they noted 146 people in front of me with no ETA in sight. The representative advised that the car was not safe to drive and they have a car at the dealership that has been waiting since November? Unacceptable. How can there be no recall if this is a known issue? The dealership noted that any fuel related issue has safety implications (fire, etc) I had a check engine light on which has since gone away. The shop ran a test and noted that the car was running in "lean" mode due to this part issue. Please advise when able, this should be a safety recall [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was operating normally on interstate traffic at 70mph when vehicle suddenly flashed "Charging system fault" and the vehicle then would not accelerate and dropped to 25 mph. Trying to exit the interstate and vehicle went into limp mode and battery icon showed up. Had to be towed to Range Rover dealership Range Rover said the issue was a DC / DC converter. They replaced this and are now saying the BISG alternator is at fault. Repairs will be close to 8k without a confirmation this will be the fix. Not comfortable driving the vehicle even with the 'fix." A vehicle "Dying" on the interstate at interstate speeds is dangerous. The problem is known on the internet and by range rover. Not sure if component has been inspected. 2021 Range Rover Sport 53k miles

The alternator on my vehicle (DC to DC convertor) went while driving home with only one sensor prompting me to turn back around and head home to be safe. The car essentially died and power steering was lost. There were no prior warnings or indicators of an issue. I had 15 minutes to make it back home. The car died in intersection, luckily at corner of my street and folks had to help push it into the driveway. Having searched for a replacement, there are no after market options, no used options, and my mechanic was told we are customer 30,335 as THOUSANDS of owners are experiencing this very same problem. The estimate weight time for the part was 3 months, at the least. So, we are stuck with an invaluable car, sitting for three months, and forced to pay storage fees at the mechanic shop as well as keeping current on the monthly car payment.

Over the last few months my warning light for engine coolant appears and says add coolant now. I will add coolant at preferred vendor. Two weeks later my coolant light will appear again saying add coolant now. When I looked myself after that 4th occasion I saw that the coolant tank was in fact empty and my car was not experiencing a sensory or electrical issue. As far as electrical my car volume will turn up and down on its on at sporadic times. I have had a professional take a look and not one service technician mentioned that I may have a possible leak or electrical problem . They just fill my fluids. However, I am certain there is a leak since my tank is empty almost every 10-14 days and my warning light is coming on to verify. I will be going back to land rover for them to do a more thorough inspection.

leaking coolant onto the Turbocharger. My coolant light has been coming on often for the past year or so. A month after I top off coolant my Warnings light indicates low coolant. I’ve been to Land Rover Range Rover multiple times with this issue, I was told there is no issue and they top it off and tell me it’s good to go, a month later same issue. I’ve noticed there has been a recall on this matter for 2019-2021 Land Rover Ranger Rover PHEV but not on Range Rover sport 2021 even though there has been many complaints about this. I went in today and I was not talking no for an answer and finally they check and as I had suspected coolant is leaking onto turbocharger. I will attach a photo that the technician from Jaguar Land Rover Fort Lauderdale has uploaded to the Service Status Tracker link, there you will see that it is the same issue that the recall was on for Land Rover Range Rover sport PHEV vehicles Recall no. 23V221000. They have not added my specific Range Rover Sport to the recall.

Mild Hybrid Electric Vehicle (MHEV) Battery Offline
ELECTRICAL SYSTEM
48V Mild Hybrid Electric Vehicle (MHEV) battery enters an offline state and no longer communicates or functions as intended. This can result in illumination of the Malfunction Indicator Lamp (MIL) ,loss of start/stop functionality and no communication during diagnostic sessions.
Body Control Module (BCM) does not fully meet US importation requirements. The BCM requires replacement with a new component which fully meets the US importation requirements.
Loss of power, rattling from underside of the vehicle and the Malfunction Indicator Lamp (MIL) illuminated on the instrument cluster. The root cause of the symptoms is the catalytic converter over temperature.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
