**Component/System:** 48V Mild Hybrid Electric Vehicle system, including the DC/DC converter subject to JLR recall D126, MHEV battery/Battery Energy Control Module, starter generator/alternator system, 12V charging system, telematics control module, and related vehicle communication/electrical modules. The vehicle and components are available for inspection upon request. **Description of Complaint:** My 2020 Land Rover Range Rover P400 MHEV, VIN [XXX], experienced serious electrical and high-voltage/MHEV system failures involving the 48V mild-hybrid system and DC/DC converter system. Before the original failure, the vehicle displayed the warning message **“High Voltage Shutdown Not Possible — System Live.”** The warning would appear on the instrument cluster while driving. The vehicle later displayed **“Stop Safely — Electrical Fault Detected.”** The vehicle then shut down while in operation, and steering assist was lost/steering became locked or extremely difficult to control. This created a serious safety risk because the vehicle lost power/drive functionality and steering assistance while being operated. The vehicle was taken to Jaguar Land Rover Parsippany for the D126 DC/DC converter recall/interim repair. The DC/DC converter is part of the 48V MHEV system and manages power transfer between the 48V and 12V electrical systems. After the D126-related repair, the vehicle would not start at pickup and had to be jump-started. The dealer later diagnosed a telematics control module issue/parasitic draw, but the vehicle continued to have electrical and high-voltage warnings. After the interim DC/DC repair, the **“High Voltage Shutdown Not Possible — System Live”** warning returned while driving. The malfunction indicator/check engine light also came on. Jaguar Land Rover Parsippany confirmed fault codes INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On March 11, 2026, the vehicle's DC/DC Converter failed completely without warning. It was towed to the Land Rover of Monmouth (NJ) where this failure was confirmed. The failure of the DC/DC converter resulted in the vehicle going completely "dead" while driving with my wife and children. There was no warning. Fortunately for my family and I, it occurred on a side street by my home and did not occur on a highway or other busy road. Had this occurred on a highway or busy road, this would have absolutely put our lives in danger. As noted, the failure of the DC/DC converter was confirmed by the Land Rover of Monmouth (NJ) authorized dealership (I have a video from the dealership stating and confirming the failure). There were zero warnings at the time it occurred; it just lost power and shut down. Based on my research after this incident, it appears to be a pervasive problem with Land Rover and while there appear to be active recalls for certain Land Rover models, inexplicably, there is no current recall for this particular model. My wife and I are very concerned that even if/when it is repaired, this will happen again. This is the primary vehicle my wife uses for transportation with our young children and I am extremely afraid of the risk that this poses to their lives. I've notified the dealership from where I purchased it and was directed to contact Land Rover USA. I have not heard back from Land Rover USA. This well-documented, pervasive defect puts lives at risk and is extremely dangerous. As an attorney, I find Land Rover's knowledge of this frequent and extensive issue -- while only having a limited recall and not providing any information to owners of other Land Rover vehicles -- is a reckless disregard for the safety of others and creates an unreasonable risk of harm to others, like my family.

I am filing this complaint regarding my 2020 Range Rover Full Size Plug-In Hybrid, which has been inoperable for over three months due to ongoing fault codes and software-related issues. The vehicle has been at an authorized Land Rover dealer for an extended period. The dealer has confirmed they are unable to proceed without direction or software updates from Jaguar Land Rover corporate engineering. For the last 60+ days, the issue has been repeatedly escalated between the dealer and corporate engineering with no actionable resolution, no repair authorization, and no clear timeline provided. I have even reached out customer relationship center file customer compliant which has not been responded to by LRNA/HQ. My case number is CASE:[XXX] Vehicle Background: •Vehicle would not charge beyond 80%. I scheduled an appointment with the local dealers to inspect. LR: Identified a coolant issue within the high voltage system. oRepair: We were able to get covered by LR per a service bulletin; however, the repair process took over a month. •November Subsequent issue: Check engine light appeared along with a “rotten egg” smell after charging. I returned the vehicle to the dealership. oRepair: LR identified power distribution box resistor out of target range with resistance causing over-charging. This took a month and believe a software issue may have caused this as well as cannot happen on non-plug in. oReplacement of both the power distribution box and battery cost $1,471. •December: Picked up the car and parked it for a week while out of town. The first week back I drove to work and the check engine light came on again. I have not yet received the vehicle back and it continues to throw powertrain codes.

The 2020 Range Rover, under warranty with 33,200 miles, has been inspected by the insurance and determined to be a total loss due to an electrical failure that caused the SUV to catch fire. The driver and a 4 year old were in the vehicle when the electrical failure started. The fire was behind the child seat, on the rear right hand seat, in the trunk compartment. The risk of serious bodily injury or death to a 4 year old and a female adult passenger was imminent. On May 23, 2023, departed my residence in San Diego, CA in my 2020 Land Rover Range Rover (hereafter referred to as LRRR) at approx 8:30 am with my 4 year old son, seated, buckled and secured in his car seat, positioned in the rear passenger side of the LRRR, enroute to his preschool, located at the Schwartz Federal Building in San Diego, CA 92101. It is an approximate 12-15 minute drive and 7 miles one direction on both surface streets and highways. The weather was cloudy approximately 65 degrees F, clear visibility on the road and dry. Approx 10 minutes into the drive, we were traveling southbound on Interstate 15 and transitioning to Highway 94 westbound we smelled something “funny” which at the time I could best describe as burning celery. As I was driving in moderate morning commuter traffic, I lowered the windows and we still smelled the odor, I raised the windows and still smelled the odor and then again lowered the windows with no change and no ability to determine if the odor was internal or external. There were no warning lights/indicators illuminated on the LRRR dash or alarm sounds. At approximately 8:45 am, I parked the LRRR on a public street, parallel to curbside in the area of 904 State Street, San Diego, CA 92101, exited the vehicle, unloaded my son and left to complete preschool drop off. Upon my return and with the LRRR in sight, I realized the windows were dark/fogged and noticed the interior of the SUV on fire. San Diego Fire Department arrived along with SDPD.

A recall was repaired on the vehicle in July 2022. Within 48 hours of repair, a high voltage warning appeared on the vehicle. The vehicle was taken in for service however the service department at Land Rover Tampa refused to check the warning because the light was not on at the time the vehicle arrived at the dealership. Approximately 2 weeks later, the low battery warning appeared on the vehicle and every electrical function of the vehicle began to shut down within 15 minutes of the warning. The vehicle was completely disabled and couldn't even have a battery jump or replacement. AAA was called and after inspection, AAA refused to sell a new battery because the diagnostics determined that the alternator needed to be replaced. The vehicle had to be towed twice before arriving to the retailer. The retailer initially attempted the repair the issue and disregarded the diagnostic from AAA by replacing the batteries however it it did not work. The retailer attempted to repair the issue 4 more times prior to returning the vehicle to the owner August 12, 2022. However, at pick up the low battery warning appeared once again and the service advisor stated that the warning would go away after driving. Less than 24 hours later, the low battery warning reappeared, the vehicle immediately began to shut down and the vehicle was completely disabled after crossing 4 lanes of traffic. The retailer towed the vehicle to its service department and attempted to repair the issue again. Unfortunately, the repair did not work and the vehicle was towed again on September 23, 2022 after the retailer was test driving the vehicle. The vehicle is still inoperable as of January 12, 2023. The vehicle is unsafe and Land Rover Corporate and all retailers are aware of this issue.
