The contact owns a 2022 Land Rover Defender. The contact stated that while driving 65 MPH, the raised air intake partially detached from the vehicle. The contact believed that the VIN should be included in NHTSA Campaign Number: 24E102000 (Equipment, Structure) after the failure. The dealer was contacted, and the contact was informed that the vehicle could not be repaired under the recall and would be an out-of-pocket expense. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 35,000.

While driving my 2022 Land Rover Defender 110 (16,658 miles), the brake pedal suddenly went soft and sank to the floor. Braking became severely degraded and effectively useless. I was able to slow the vehicle using engine braking and bring it to a stop safely. Multiple warnings appeared simultaneously, including brake system warnings, amber ABS and DSC lamps, and a "stability control not available" message. There was no crash, fire, or injury, but the loss of braking created a serious risk to me and the surrounding traffic as I was making a left onto [XXX] against oncoming traffic on [XXX] The vehicle was not driven further and was taken to an authorized Land Rover dealership for diagnosis. The dealership's diagnostic scan confirmed DTC C055E-7A ("Brake Hydraulic Circuit A Leak – Fluid Leak or Seal Failure") logged on XXX, along with related code C055E-64. This confirms a hydraulic fluid leak or seal failure in the service brake system, consistent with the total loss of pedal pressure I experienced. The manufacturer has issued Special Service Message SSM 74988 addressing this exact DTC on this platform (Defender L663, 2020 model year onward), indicating awareness of this failure mode. There were no warning lamps or symptoms prior to the failure — it occurred suddenly with no advance indication. The vehicle and diagnostic records are available for inspection upon request. Root-cause diagnosis by the dealership is in progress; the suspected sources are a hydraulic line, caliper, seal failure, or the integrated brake unit (which combines the booster, master cylinder, ABS pump, and control module in a single assembly on this platform). A sudden hydraulic brake failure at this low mileage suggests a potential defect rather than wear. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident

Jan 27, 2026

On 4/2/2026, my DC to DC converter failed in my 2022 Landrover Defender (owned 3 months, purchased pre-owned from dealer), which short-circuited both my 12V battery and my telemetric safety battery (location services, and emergency calls). The vehicle lost all power, completely malfunctioned electrically losing ability to accelerate, power steering, and everything went dark in the vehicle while driving on a highway. I immediately tried to get it to the shoulder but it lost momentum and stopped in the lane, with cars and semis coming around a blind corner at speed. It was a harrowing experience, the car started to roll backwards (on a slight incline, as it was a mountain pass) and a semi truck had to assist in stopping the vehicle by skillfully, using his trailer to stop the vehicle. This created body damage to the entire side of my vehicle. The car then locked up completely, wheels were locked and tow truck had to drag it with a chain up on the bed. My son and I could have been killed, as traffic was coming around the bend at 60-65 mph and we were completely stopped and started rolling back towards the oncoming traffic. Several others could have been injured as my vehicle could have cause a major traffic collision. The issue has been reported to Jaguar Landrover customer service, reported to the dealership I bought the vehicle from and to the dealership who told me that it could help to drive the vehicle to charge the battery. The dealer where I towed the vehicle confirmed it was the DC to DC converter failure, confirmed that it fried or short-circuited both batteries which then caused the car to lose all power. The failure was confirmed by certified mechanics, and approved by an inspector for the extended warranty and repairs were made. There was an electrical fault warning on screen. One dealer told me to drive it to charge battery. This vehicle should be recalled to avoid safety issues.

I believe there is an issue with the DC to DC converter. Had an incident when the vehicle was idling for at 30 mins while cleaning snow in driveway after a storm. I received an warning battery low. As thought this was odd I turned it off. waited a few hours returned and the warning was gone. I had JLR dealer look at the issue. I was told the main battery was faulty and replaced, this was in end of DEC 2025. Then weeks later [around Jan 18th 2026] when it was really cold out and driving to JFK airport. while in route i received an very generic electrical system fault warning. As i was leaving 1 of the terminals at JFK. on the exit ramp of the terminal I had complete electrical failure was lucky enough to be able to be able to pull to shoulder, but was coasting about 1-2 mph, and stop. It took 3 attempts to restart the vehicle, when it started normally and all electrical was acting normal. if this happened while on the highway it would have caused an accident and i believe injuries. i will say the hazard warning lights were still working. I have also been noticing that the digital dashboard display brightness will fade in and out anytime of the day and weather randomly. Today this happened and received a low coolant warning and a tire low warning at the same time. I check the coolant level and it is normal. I check the tire pressures and they are normal.

The vehicle lost power after a warning that the battery was not recharging. I have a portable jump start battery. Tried to jump start it -- the battery would not hold a charge once cables disconnected. Had the vehicle towed to the dealer. I was told this is a DC-to-DC converter problem that is widespread across Defenders 20222-present. parts are unavailable.Being stuck in a vehicle with no power, absolutely dead, is scary and would have been a major problem if the electrics had gone out while driving.

While driving on a busy road. My car gave a message saying electrical failure and transmission failure. Within 20 seconds shut the car down before I could safely pull over and it was unable to start. Hazard lights didn’t work and I was stuck in the middle of the road until a tow truck came. The dealer diagnosed the problem as a failure of the dc to dc converter. It has been replaced but took two weeks to repair

Daytime running lights has failed on the front headlights and follows pattern similar to known Special Service Message 75479. This reduces safety due to lower visibility since the DRLs should operate during normal driving conditions. I have reached out to the dealer and the Land Rover Corporate, both of which refuse to fix the issue unless I pay for parts and labor (est cost $5000+). This issue is dangerous since there is no indication on the dashboard or other warning unless the headlights are manually inspected while the vehicle is operating.

The DC converter on our 2022 Land Rover Defender 110 failed. We received some electrical fault notices that would come and go inconsistently a few days before the incident. Land Rover told us to drive the car to the dealer to get repaired, even when we asked whether that was safe. On the way to the dealer, the car completely turned off in the middle of traffic and became a brick and had to be towed in negative degree weather to the dealer where it has sat for a month today. The car shutdown/lost control on Rt 1 in Massachusetts and was fortunately able to steer off the road into a parking lot before it became a brick in the middle of a parking lot, not in a spot or anything. The dealer expects this is a DC converter problem but the car is a complete brick and cannot turn on or be moved around at the dealer until the part arrives. We've been told the part is on back order for months and there is no timeline for when it will be repaired.

DC to DC converter failure that displays a RED warning indicator that says "Stop Safely Electrical Fault Detected" with a red battery indicator symbol displayed simultaneously. I called the dealer as this is the 3rd time I have experienced similar electrical issues that have left me stranded since my purchase of this truck new Jan '22. The dealer brushed me off the first time telling me I didn't drive the vehicle enough, 2nd time they replaced the battery, now they said they had a bulletin (1 month prior) from Land Rover of known DC-DC converter failure with no ETA for parts. I was told by the dealer the steering could lock up and/or the vehicle could have brake failure. I had it towed 1 hour to the dealer. There are 10 other vehicle sitting at this one dealer awaiting the same part replacement and they never notified me of this issue when they were aware of the safety concerns a month prior to my 3rd incident. This is a now known nationwide issue with Defenders and I have a claim in for it to be covered under the factory warranty since my factory warranty had just expired 9 days prior especially given my prior record of electrical issues with this particular vehicle. This is still not resolved and it has been at the dealer for 18 days as it is not safe to drive and still awaits a part with no estimated time for repair.

On January 25, 2026, while driving my 2022 Land Rover Defender 110 in Colorado on Interstate 70, the vehicle suddenly and completely lost power with no warning. There were no dashboard alerts, warning lights, or messages prior to the failure. The vehicle abruptly became disabled while traveling at highway speed, creating an immediate and serious risk of a crash, severe injury, or death to myself and other motorists. I was extremely fortunate to be able to safely maneuver the vehicle out of traffic and exit the highway. Given traffic conditions on I-70, this failure could easily have resulted in a major accident. The vehicle was undrivable and had to be towed to Flatirons Land Rover in Colorado on January 25, 2026. On January 26, 2026, after I had to repeatedly follow up with the dealership, I was informed that the failure was caused by a defective component related to the battery/electrical system. Although the repair is covered under warranty, the required part is on backorder, and I was advised the vehicle will be out of service for approximately six weeks. The dealership stated they cannot provide a loaner vehicle, leaving me without transportation. They said the dcdc converter and I don not understand and they did not explain well A sudden loss of power without warning at highway speeds represents a serious safety defect that puts drivers and the public at risk. I am concerned this defect may affect other vehicles and could lead to serious injuries or fatalities if not addressed.

Safety Complaint – DC-to-DC Converter Failure Causing Vehicle Shutdown I am submitting this complaint to report a DC-to-DC converter failure that rendered my vehicle inoperable. The authorized Land Rover service department diagnosed a failed DC-to-DC converter. This component is part of the vehicle’s electrical system and its failure caused a loss of vehicle functionality. I was informed the replacement part is on national back order, with an estimated repair time of up to two months. Based on owner reports and service discussions, this appears to be a common failure affecting Land Rover mild-hybrid vehicles. Many reports describe sudden loss of electrical power, warning messages, and vehicle shutdown. This issue presents a potential safety risk, as failure of the DC-to-DC converter can result in loss of vehicle systems and may occur without warning, including while the vehicle is in motion. The vehicle is currently unusable. It is concerning that a critical electrical component with safety implications is failing at relatively low mileage and that replacement parts are not readily available. I am requesting NHTSA review this issue for potential investigation, recall, or other corrective action.

Vehicle display provided warning of Electrical Fault and shorty thereafter the vehicle "bricked" ie. became entirely inoperable. I was able to jump start the engine but as soon as the vehicle was disconnected from the jumping power source the vehicle's engine shut down. The vehicle was towed to the dealership. The tech with the towing truck jump started the vehicle and noted the problem appeared to be with the alternator (ie. excessive draw on the power source). The dealership has tentatively diagnosed the problem as the DC-DC converter which serves as the alternator in this vehicle. The part has been back ordered for quite some time. The failure of this component seems to be a widespread issue with a number of Land Rover models.

On [XXX], while driving approximately 30 mph, my vehicle displayed the warning “STOP SAFELY – ELECTRICAL FAULT DETECTED.” I immediately pulled over and restarted the vehicle, but the warning reappeared. Due to safety concerns and proximity to my home, I cautiously continued driving. Two blocks from my residence, I stopped briefly and received a message stating “BATTERY LOW – PLEASE START ENGINE.” After restarting and turning the vehicle off again, the original warning cleared; however, the vehicle has been completely inoperable since [XXX]. The SUV was towed for battery replacement and then towed again after diagnosis confirmed a failed DC-DC converter. The dealership has advised the earliest availability of the replacement part is February 19, 2026, resulting in over two months of total vehicle downtime. I have received minimal updates during this time. I reported this issue to Land Rover/JLR but have not received follow-up or resolution. Based on my research, DC-DC converter failure is a known safety issue, and JLR has prior awareness of this defect. This failure presents a serious safety concern due to loss of electrical function while driving, possibly emergency brake issue, along with unreasonable repair delays related to a known issue. I am requesting acknowledgement of this safety concern, clear communication regarding my case, and appropriate assistance due to the extended downtime and still having to pay a monthly car payment/insurance and manufacture warranty just expiring at the 50,000 miles.
