On XXX at approximately 8:10am I received this red warning on my vehicle: "OK to drive with caution. Hybrid system fault detected." I was driving my daughter to daycare at the time and didn't feel safe continuing to do that. My wife had to drive 25minutes to come and get us and safely continue our trip. No other issues with the vehicle prior to this incident. A month or two prior to that, I had received the recall notice regarding a failure of the DCDC converter and that an electrical fault warning could potentially happen. Well I got that warning and then my check engine light remained on. I immediately called [XXX] Jaguar Land Rover in [XXX] and got an appointment for the following Wednesday, August 5th. I was put in a loaner while they checked out the vehicle. On Wednesday, August 12th, I heard back from [XXX] regarding my vehicle and this was the message I got from the system: [Primary]: LCEL - CHECK ENGINE LIGHT DIAGNOSIS: CHECK ENGINE LIGHT DIAGNOSIS CHECK ENGINE LIGHT - DIAGNOSIS - CUSTOMER STATES ON SOLID, VEHICLE SEEMS JERKY Check Engine Light - Diagnosis-Land Rover: MHEV BATTERY will need replaced. ran multiple tests on topix thru the work flow. DTCs confirmed internal malfunction to MHEV BATTERY. it will also need programmed once installed. includes hour of diag My rep followed up and let me know that this was going to be outside of my extended warranty coverage. I followed up asking about the recall and the relation to this incident. He responded and said he still had very limited information in regards to that recall, so once parts and repair procedures are released, I could be entitled to reimbursement. I'm failing to understand how LandRover wouldn't cover this. It's directly related to the recall notice I got in April, and then what they described could happen, effectively happened to my vehicle. I did not feel safe driving it so I didn't drive it until it was time to drop it off. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Three days before leaving for a trip from [XXX] to [XXX] my Land Rover Defender gave me a Low Battery warning. There was no time to take it to the dealership so I bought a new battery and put it in myself, then drove the 700 miles to [XXX]. My family and I were traveling in a remote area 6 miles from our vacation rental, with no cellular service, when our Defender suddenly threw an electrical fault warning on the dashboard asking us to pull over safely, on XXX. We made it to the vacation rental, then I borrowed a family member's car and went into [XXX] to buy tools to see if the battery was charging and if I could safely drive it to the nearest dealer or even home. It was not charging. So I called the dealership (Land Rover Rocklin) and had the car towed to it, then rented a truck to finish my vacation and get the family and our gear home. At the dealership, Rocklin required a brand-new factory battery to run tests on the failed DC-DC converter. They confirmed the converter failed under Recall 26V-248 and replaced the unit with the same recalled part. To get through this ordeal, I incurred $3,036.13 in direct out-of-pocket costs (towing, rentals, batteries, tools). Despite written confirmation from Jaguar Land Rover Corporate Customer Care agreeing to reimburse these recall expenses, Jaguar Land Rover has since passed me between departments, applied arbitrary roadside assistance caps, and ultimately refused to issue a refund, imposing an illegal financial burden on me to remedy a federal safety defect. I can supply all receipts. Specific Incident Details Component / System Failure: The DC-DC Converter failed internally (NHTSA Recall 26V-248 / JLR Campaign D126), causing a complete loss of 12V charging. Safety Risk: The failure occurred on remote mountain roads without cell service. A complete loss of 12V power threatens power steering, braking assistance, and vehicle propulsion while driving.

NHTSA complaint #11753125 — an unverified report by a vehicle owner.
My 2020 Land Rover Defender 48V Mild Hybrid Electric Vehicle (MHEV) experienced a check engine light and hybrid electrical failure. Diagnostics by an authorized Jaguar Land Rover dealer confirmed code P0A1F-96 (Battery Energy Control Module / BECM internal component failure). This failure relates directly to an active, global safety recall issued by JLR (NHTSA Campaign 26V248 / JLR Recall D126) regarding DC-DC converter failures in MHEV vehicles. According to JLR recall documentation, a microchip failure in the DC-DC converter causes a total loss of 12V system charging, leading to electrical warnings and a sudden loss of motive power/propulsion while driving. CHRONIC CHARGING SYSTEM FAILURE: This vehicle has suffered from unresolved, long-term 12V charging system degradation caused by this MHEV subsystem defect. This chronic lack of proper charging has directly destroyed three (3) primary 12V main batteries and the emergency telematics (SOS) backup battery over a 4-year period. Replacing these auxiliary batteries failed to fix the underlying issue because the MHEV system/DC-DC converter continuously fails to maintain adequate charging across vehicle systems. This continuous voltage collapse eventually triggered the permanent BECM hardware lockout code (P0A1F-96). SAFETY HAZARD: A sudden loss of 12V system charging and subsequent loss of propulsion on public roads or at highway speeds presents a severe crash hazard to occupants and other motorists. STATUS & DEALER REFUSAL: An authorized JLR dealer confirmed code P0A1F-96 and documented "Pending Recall Campaign D126ADM2" on the official service invoice. Despite this being an acknowledged, safety-related defect in the MHEV system leading to loss of drive power, JLR North America and the dealer refuse to repair or grant goodwill coverage under the active safety recall framework, quoting over $3,400 out-of-pocket. The vehicle is available for inspection.

The recent DCDC converter recall has left me feeling unsafe driving my Defender on anything except the slowest local roads. It's an extremely frustrating inconvenience, especially during this summer season with plans for road trips and travels being put on hold or cancelled due to not having a safe vehicle. Also, the JLR dealership is not offering loaner vehicles because the recall remedy is not available yet. There is no timeline for when the remedy will be developed, which is the cherry on top. That means I have to pay out of pocket, indefinitely, for a rental car on top of paying the car note for the Defender. Did I mention that JLR "conveniently" waited almost 60 days from the time they submitted the recall notice to NHTSA to send out the interim letters? They put me and over 150,000 other drivers at risk for nearly two months because they decided to take their time in mailing the letters out (I received mine on June 17th). This removes all confidence I would have had in their ability to develop the fix in a timely manner.

I own a 2020 Land Rover Defender and have experienced a failure of the LED halo ring/daytime running light within the headlight assembly. The LED ring stopped functioning even though the headlight assembly has not been damaged, modified, or involved in any accident. This failure affects the vehicle's visibility and appearance and may create a safety concern because the daytime running light is no longer operating as intended. I contacted the dealership regarding the issue, but I was informed that the repair is not covered under warranty, despite similar LED halo and DRL failures being reported by other Defender owners. I am requesting that this issue be investigated, as it appears to be a defect in the headlight assembly rather than normal wear and tear.

The DC/DC converter failed and caused the vehicle to immediately lose all power at a main intersection. My wife was driving the vehicle when this happened with out two children in the vehicle as well (ages [XXX] and [XXX]. Luckily, she was able to somewhat get out of intersection of a very busy road. The vehicle had to be towed to the Land Rover dealership. The part was covered by a factory extended warranty. There is an active recall for this part; however, this vehicle does not show to be in the recall. Since this part did fail, I wanted to file a complaint since it is not in the recall.

The manufacturer became aware of this issue approximately six months ago. At this time, no repair is available. I am driving to a remote location without consistent phone service and the manufacturer and dealer will not offer a loaner vehicle. I believe that Land Rover should offer a trade in for a new vehicle without this issue.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle appears to have experienced a failure or malfunction involving the electrical power system, charging system, 12 volt battery system, vehicle communication modules, or related components. Based on the recent Land Rover recall I found online, I am concerned that the DC to DC converter or related charging system may be involved, because the reported recall issue involves loss of 12 volt charging and potential loss of drive power. The vehicle is currently with Jaguar Land Rover Houston Central and should be available for inspection upon request. The vehicle has not been returned to me, and the dealer has indicated that the vehicle was not communicating with their diagnostic computer and was not initially showing fault codes because the modules were not communicating. They have told me that my car is not part of the recall. How was your safety or the safety of others put at risk? My safety and the safety of others were put at risk because the SUV experienced a complete shutdown while I was driving on two separate occasions. The first event occurred Thursday afternoon at approximately 4:32 PM while I was driving on Highway 610. The vehicle suddenly lost power while in motion. I was able to glide off the highway and park on the side of the road, but this could have caused a crash or created a serious hazard because it occurred on a major roadway. The second event occurred Friday morning around 7:20 AM while I was driving on South Rice Avenue to take my daughter to school. The vehicle shut off again and left me stranded. Multiple people attempted to jump start the vehicle, including the tow truck driver, but the vehicle could not be restarted or shifted into neutral. The vehicle remained disabled and required towing. Because the shutdown happened while driving and the vehicle could not be restarted or moved normally afterward, this created a significant risk of co

SUPPLEMENTAL TO NHTSA COMPLAINT #11728718 (RECALL 26V248000) On March 2, 2026, my 2023 Land Rover Defender was at a dealership for approximately 3.5 hours for key fob programming. At that time, Jaguar Land Rover had an active service message (SSM76173) related to DC-DC converter failures. Within 24 hours of leaving the dealership, the DC-DC converter failed. The vehicle displayed a “Charging System Fault” warning and became inoperable, consistent with the failure described in my original complaint #11728718. I contacted the dealership immediately with information about the issue. They told me that what I experienced aligned with the DC Converter failures that have been reported. I asked if I could get my Defender picked up or if they could at least provide a loaner car if I could somehow get my Defender to them. The dealership declined towing assistance and did not provide a loaner vehicle, citing that I was beyond the mileage limit of the warranty. I was also told that loaner vehicles were reserved for customers who purchased their vehicle at that location. Because I live approximately 4 hours from the dealership and the vehicle was not safely operable, I arranged my own repair. Due to a national backorder, the vehicle was unusable for an extended period (about a month). I purchased a genuine replacement DC-DC converter and paid for expedited shipping. Total out-of-pocket cost exceeded $970. On April 23, 2026, Jaguar Land Rover issued Recall 26V248000 for this defect. Communication with JLR about this incident started on April 7, 2026. On April 23, 2026 at 8:05 am EST (following the announcement of the recall), I was offered a final settlement off of a $458 retailer credit. However, I was instructed that I needed to return to the dealership (4 hours away) for inspection of a vehicle that has already been repaired using an OEM part. I am submitting this update to document the failure, the repair, and the manufacturer’s response following the recall.
NHTSA complaint #11733338 — an unverified report by a vehicle owner.
While driving my 2024 Land Rover Defender 130 on Route 114 in Massachusetts at approximately 8:30–9:00 PM in dark and rainy conditions, the vehicle suddenly and completely shut off while in motion. The vehicle lost all power: • Engine shut off • No gears functioned • Vehicle would not restart • Lights and hazard lights were not functioning The vehicle was stranded in the middle of an active roadway with no warning and no visibility. Because of this, I had to exit the vehicle into traffic, stop oncoming vehicles, and remove my child from the car. We crossed a live lane of traffic to get to safety while leaving the vehicle in the roadway. I called 911. Police responded and controlled traffic at the scene. In the presence of the responding officer, I attempted to restart the vehicle multiple times. It remained completely unresponsive for an extended period before eventually starting again without explanation. This vehicle experienced a sudden loss of power while in motion on an active roadway. This is a serious safety concern. I do not feel it is safe to transport my child or family in this vehicle. I am seeking a clear and definitive diagnosis and resolution. If this issue cannot be conclusively identified and repaired, the vehicle should not remain in service. • RSelect systems: • Engine • Electrical • Powertrain
