Supplement / update to prior NHTSA complaints regarding my 2021 Land Rover Discovery MHEV (VIN: [XXX] y prior complaints, Jaguar Land Rover has issued Recall 26V248 for DC/DC converter failure leading to loss of propulsion in 2021–2024 Land Rover Discovery MHEV vehicles. My vehicle experienced the same real-world failure condition: sudden loss of propulsion in traffic with my children in the vehicle. Jaguar Land Rover corporate has stated my VIN is not included in the recall population despite my vehicle being a 2021 Discovery MHEV and experiencing the same defect condition. I am submitting additional documentary evidence from Jaguar Land Rover Portland showing that during the repair process: * I was advised the vehicle would only run while connected to external jumper power and would shut off once that external power was removed. * Two days later, I was advised the installed battery would only charge to 6 volts and that another battery was needed to continue testing. These communications raise concern that this failure event involved broader electrical consequences and further support that my vehicle experienced the same defect condition described in Recall 26V248. The dealership ultimately completed repairs and charged me for the failure, while JLR maintains my VIN is excluded. I am requesting NHTSA review whether my VIN was improperly excluded from the recall population and whether the affected vehicle population should be expanded.

I am filing a safety complaint regarding a sudden and complete loss of power event while driving my 2021 Land Rover Discovery. The vehicle experienced a DC-DC converter failure with no warning, resulting in a sudden shutdown. The engine lost power, critical systems went offline, and I was unable to shift the vehicle into neutral. The vehicle became immobilized in active traffic, creating a dangerous situation. This incident occurred without warning and left me with no ability to safely move the vehicle out of traffic or rely on normal emergency functions. This presents a serious safety hazard to both the driver and others on the road. The vehicle has been at the dealership since mid-January 2026. The dealer has stated that the DC-DC failure caused additional component failures. However, no root cause has been identified beyond “internal failure,” and I have not been provided confirmation that the system has been properly tested or that the issue will not recur. I am concerned that this failure can cause cascading electrical issues, including loss of the 12V system, impacting multiple critical vehicle functions at once. The lack of a clear diagnosis and verified repair raises concerns about reliability and safety. Given the sudden loss of power, inability to move the vehicle, and absence of a confirmed root cause or validated repair, I am formally requesting that the National Highway Traffic Safety Administration open a defect investigation into the MHEV/DC-DC system. This failure creates a significant safety risk, including vehicles becoming immobilized in active traffic without warning. The risk of recurrence without a defined cause is especially concerning and may indicate a broader issue.

While driving my 2021 Land Rover Discovery (MHEV) in active traffic, the vehicle suddenly displayed an “Electrical system fault – Stop safely” warning. Immediately after the warning, the vehicle lost power and shut down, leaving me stalled in traffic with no ability to safely move the vehicle out of the roadway. There was no prior warning, no gradual degradation, and no driver-caused condition. The shutdown appeared to be related to the 48-volt mild-hybrid electrical system, possibly involving the DC-DC converter or battery management system, which disabled critical vehicle functions. This failure created an immediate safety hazard. I was at risk of being rear-ended and had limited ability to safely exit traffic. The vehicle became effectively inoperable without warning, which is unacceptable in real-world driving conditions. What is especially concerning is that: •The warning instructed me to “stop safely,” yet the vehicle did not allow time or power to do so •There were no visible issues beforehand •The issue appears consistent with known Land Rover MHEV electrical failures •Software updates were present, but did not prevent the failure A sudden electrical shutdown in traffic poses a serious safety risk to drivers, passengers, and others on the road. This issue should be investigated for potential defect, recall, or mandatory repair, as it compromises safe vehicle operation.

MHEV vehicle is offline; car completely shut down, resulting in loss of power on the road.

I own a 2021 Land Rover Discovery with VIN [XXX] , and I am experiencing issues that align with the national recall for the MHEV battery. My vehicle’s start-stop functionality fails intermittently, and the system is in an “offline state,” disrupting communication and critical functions. Additionally, due to these MHEV battery errors, my vehicle cannot receive over-the-air updates provided by Land Rover, further impacting its performance and reliability. I request that my vehicle be reviewed for inclusion in the recall and that the necessary repairs be covered. This ongoing issue presents a significant inconvenience and safety concern.

This is an update to Complaint Number 11436854, submitted on 10/14/2021, 5:53:21 PM Additional service has been performed on the vehicle to identify and correct random electrical faults interrupting the safe operations of this vehicle. Service record generated by Land Rover Boise, ID (RO Number 520844) is attached as an uploaded file. This RO indicates the third repair by Land Rover dealers that have serviced this vehicle (Lynnwood, WA; Flatirons, CO and Boise, ID) regarding the Ground Stud Update, and now provides the documentation of another ground fault in the Locking Actuator (door locks are randomly actuating w/driving).

This vehicle should be considered as a "drive at your own risk" vehicle. Engine randomly fails to start using push button start in coordination with pressing on the brake pedal. Dash and gages indicated all electrical systems were on and no warning symbols were displayed. Repeated attempts by owner to start vehicle failed. Attempts using remote start app erroneously indicated that the vehicle was already in operation. Fail-to-start generally existed for 2-4 hours before the vehicle would randomly start. Failure to start and stranding owner repeated 4 times over the next 8 days, including while the vehicle was in service shop of Dealer. Dealer service could not identify source of the problem and produced records that the safety recall for the battery ground stud issue had already been performed. Dealer service records (attached) recommended against driving vehicle due to "what seems to be intermittent high speed power train communications fault". Owner has requested Dealer By Back due to this repetitive and unresolved safety problem. Refusal from Land Rover to buy the vehicle back places this consumer safety issue back into owners hands which triggered the moral obligation to submit this information to the NHTSA as a safety problem.

After 2000 miles of driving, I received a warning that I had reduced traction and needed to drive with caution. When I took vehicle to dealer they determined the “initial configuration was not complete”.

Received an error message stating reduced traction only 2 wheel drive and to drive with caution. Took it to the dealer to discover the software was not programmed for the 4wd modules

Our DC converter caused an electrical malfunction which is apparently such a big problem that our dealership can not get the necessary parts to fix the problem. We are being told we are number 21 in line.

DC/DC converter failed (January 2025) and is sitting at the dealership. My vehicle completely shut down while I was driving on the interstate. I had the same issue in April 2024 and was without my vehicle for nearly 2 months.

DC DC converter failed while driving. Car shut down and rolled to a stop. Could jump start the car but would only work for 10 seconds or so to move it out of traffic. 1-2 month part delay.

The DC-DC converter went out in December. The vehicle has 53,000 miles on it, so it is just out of warranty. I live 100 miles from the nearest dealership so I had it towed to a local shop. I was originally told the part was on back order until Mid-February. I was told yesterday, they think it may not be available until May 2026. If this is such a big issue that they can not keep up with the part, why is this not a recall item?

Perrelli Scorpion 255/55R20 tires experience experience excessive wear down to cords in under 15K miles. Tires are in adequate to support the weight of the vehicle.

Dear NHTSA, I am writing to report a safety issue with my 2023 Land Rover Discovery Metropolitan that occurred on April [XXX] 2024. VIN: [XXX] The issue involved the steering wheel locking unexpectedly. After parking the car overnight for 15 hours, I returned to find a message indicating lane departure assist wasn't working, and the steering wheel was completely locked and inoperable. I attempted various troubleshooting steps, including changing driving modes, restarting the car, and checking for software updates, but none resolved the problem. While the car functioned normally in terms of forward and backward movement, the locked steering wheel prevented any turning ability. There were also no warning lights or error messages displayed on the dashboard. The only solution I found was to perform a hard reset by disconnecting the negative battery cable for 3 minutes and then reconnecting it. It's concerning that a similar issue appears to be reported by other Land Rover owners online, particularly with Defender models. [XXX] My primary concern is the possibility of this malfunction occurring while driving, which could lead to a serious accident. There seems to be no guarantee that this isn't a potential risk. I will be in contact with the Land Rover dealership locally and urge NHTSA to investigate this potential safety concern with Land Rover vehicles. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was in a parking lot adjusting settings via the touch screen when the vehicle suddenly deactivated the key fob rendering the vehicle useless. The only option was to get the spare key to start the vehicle. This presents a safety issue for all occupants if the vehicle is disabled because of a malfunction with the key, potentially leaving people stranded in a unsafe environment.

I was driving home from work late at night in December 2025. A Signal came on that said pull to safety or something like that and then I lost power steering and brake control and my entire dash in my vehicle went pitch black. I was in the middle lane on route 290 and I was very lucky not to hit any other vehicles, but it was incredibly scary because I had no control of my vehicle and there were many cars and trucks on the road around me. I coasted off slowly to the side and I had to sit in 15° temperatures for an hour while I waited for AAA to come and tow my vehicle. They towed it to my home and were not able to get it off the ramp so they had to tow it to the dealership because the battery had died. The vehicle for a couple weeks before was slow to start, which I did not realize at the time was a sign that the battery was being drained. It was brought to the dealer and discovered that the DC DC converter and the BECM was the issue. My vehicle is open for inspection if you need it. The converter and BECM have been replaced after fighting with the dealer and with Landrover. Landrover is aware of the situation because they had to work with the dealer on their systems.Unfortunately, I am out almost $1000 because they made me pay for the replacement of the battery ( and the towing ) . Honestly I am having PTSD every time I drive past the area where I almost crashed. Landrover did not even want to accept responsibility, but the dealer did as we have purchased two vehicles from them that we also maintain meticulously.

The failing component is the same as Land Rover Discovery 2017-2020 recall /N221 service action. Complaint is to extend this service action/ recall to later production models of Land Rover Discovery in the years 2021 and 2022. The same issues are occurring as reported with Land Rover discovery 2017-2020. Due to a faulty sealant mechanism, the windshield is leaking water on the inside of vehicle causing visual impairment whilst driving in rain, snow and wet conditions - an unsafe way to drive. The water is also known to leak into electrical components causing cameras to not work, causing steering issues and causing electrical safety warning systems not to function. Land Rover Discovery (specifically 2017–2020 models) has faced issues with water leaking from the windshield, causing potential electrical damage and cabin moisture, as detailed in a Service Action (N221) and a 2020 class-action lawsuit. While often handled as a technical service bulletin (TSB) rather than a safety recall, dealers are instructed to inspect and, if necessary, replace the windshield.Key Details Regarding the Windshield Issues:Affected Vehicles: Primarily 2017-2018 Discovery 5, though reports have continued for 2020 models.Problem: Improper sealing leads to water leaks, causing moisture in the cabin and potential damage to electrical components.Service Action/Recall: Service Action N221 outlines instructions for dealers to test for leaks and replace the windshield if necessary, under certain circumstances.Action Needed: Owners experiencing this issue should contact their local Land Rover dealership for a check, as it may be covered by the manufacturer's warranty or a goodwill repair. However, service dealers who I have called are requiring me to pay $250 for a diagnostic of their own issue. As well as keep the car for several days just to evaluate.

The DC/DC converter had failed after the recent software upgrade by JLR right in the middle of the road. Barely made to their shop. It has been a month since. No updates on the status of the fixing my car. Had call many times, no response. The car is in the JLR diller in Hunt Valley, Maryland.

The contact owns a 2022 Land Rover Discovery. The contact stated that while driving at an undisclosed speed, the vehicle jerked, and several unknown warning lights were illuminated. The vehicle was pulled over to the side of the road and turned off. The contact waited before restarting the vehicle; however, after driving for several miles the failure reoccurred. The contact stated that on a separate occasion, the vehicle jerked, and the vehicle failed to accelerate as intended while depressing the accelerator pedal before the vehicle stalled. The message "Emergency Braking Assistance Not Available" was displayed. The contact was able to coast to the side of the road. The contact called for assistance and another driver arrived the scene and followed behind the vehicle back to the residence. The vehicle was taken to the dealer, where it was diagnosed that the ground studs were not connected and had failed to function as intended. The vehicle remained at the dealer unrepaired. The contact stated that before the electrical failure, the message "Check Coolant" was displayed. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 21V457000 (ELECTRICAL SYSTEM); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 76,000.
