2023 Land Rover Defender

My 2023 Land Rover Defender is subject to manufacturer recall D126 / NHTSA Recall 26V-248 concerning potential failure of the DC/DC converter due to an internal fault in the boost control microchip. The recall remains incomplete and Jaguar Land Rover has advised that a remedy is not yet available. I have contacted Jaguar Land Rover and my authorized Land Rover retailer, but there is currently no repair that I can have performed to remedy the safety defect. This has created a significant problem because I recently relocated from Canada to the United States and need to import my Canadian-market Defender. Jaguar Land Rover will not provide the manufacturer compliance documentation required for the normal U.S. importation process while this recall remains outstanding. However, I cannot have the recall completed because Jaguar Land Rover has not yet developed or made a remedy available. I am therefore effectively unable to remedy the safety recall through no action available to me as the vehicle owner, while the unresolved recall is simultaneously preventing me from importing the vehicle into the United States. I have asked Jaguar Land Rover for assistance and am currently discussing a potential manufacturer buyback because there is no available recall remedy. I am requesting that NHTSA review whether Jaguar Land Rover is providing an appropriate and timely remedy for Recall 26V-248 and advise what recourse is available to an owner whose vehicle cannot be remedied because the manufacturer has not yet made a repair available.

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.

While driving on the freeway I recieved and elctrical fault detected please pull over when safe. The issue is the DC to DC converter failed resultign in the loss of charging for the car and relaince on stored elctricity in the battery to drive systems. I was on the highway at freeway speeds and had to exit the highway quickly to avoid the vehicle completly shutting down on the freeway. The dealer has verified the issue. There is significant discussion on owner boards about the numerous failures across all years of the mhev defender resulting in owners being stranded on the side of the road. Land Rover needs to issue a recall to replace this defective part.

The DC to DC converter Failed. It is part of the mild hybrid system. Multiple cars in my state and globally have reported the same failure around the same time. Supposedly these failures are due to the cold weather. At the 1st start up of the day a warning message displayed "Stop safely Electrical fault detected" the it disappeared after 1minute. After the 2nd start up the message reappeared and stayed on. I drove straight to the dealership where the vehicle would not be able to start or move again. My safety and others would have been at risk if the vehicle would have been immobile on the road. The vehicle has since had the DC to DC converter replaced as well as the battery which suffered power drain. These repairs were done by the manufacturer/dealership under warranty. The DC to DC converter was on back order for months due to so may vehicles suffering the same failure. With more cold weather ahead is the replacement part or system safe? I think this issue needs to be investigated.

On several occasions my car has shifted from Drive into Neutral while I was at a light and the vehicle had shut itself off as part of the Intelligent Start Stop feature. I see that this same issue has been happening to several other Owners who have reported this to the NHTSA. Ironically it seems as though all these vehicles were purchased in Houston TX.

Stopped on an uphill grade, start stop on vehicle activated, engine stopped. Upon brake release, engine started, vehicle made uncommanded shift from drive to neutral, rolled backward several feet before brake could be reapplied. Land Rover has been aware of the uncommanded shift to neutral issue for sometime. Local dealer has a bulletin on this issue, but Land Rover has no fix, instead advising to manually disengage auto start stop every time vehicle is driven. Unfortunately, sometimes I forget to do this. It’s a problem.
