2023 Land Rover Defender Problems

DC/DC converter failure, left my wife stranded. Software update failed to fix. Car is undrivable. Land Rover won't assist with towing or paying for repairs even though this issue is covered under NHTSA Recall Number 26V-248.

The contact owns a 2023 Land Rover Defender. The contact received notification of NHTSA Campaign Number: 26V248000 (Electrical System); however, the part to do the recall repair was not yet available. The vehicle was taken to a local dealer and remained with the dealer for additional investigation. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue, and a case was filed by email.

The contact owns a 2023 Land Rover Defender. The contact stated that while driving 67 MPH, the vehicle lost automotive power, and all electrical features shut off. The vehicle was towed to a dealer where it was diagnosed, and the contact was informed that the failure was not duplicated. The vehicle was towed to another dealer to be diagnosed, and the contact was informed that the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was 43,000.

A warning sign appeared stating the battery was not charging (something like that). When I turned off the car, another warning said to keep the car turned on the battery was low. I kept the car on and began to drive home, very quickly more warnings appeared, power was diminished, so I pulled into a parking lot and the car completely stopped. Tried to turn engine back on to get it into a parking spot, It would not start. Could not put the care in neutral to push it out of the way. Tried to put my hazard lights on, but they would not turn on. Had it towed to a shop, they told me it was a recall, towed it to JLR (Flatirons), and there it sits. Called JLR USA, they told me not to drive it until the recall repair is made, and it looks like January 2027 is the date there will be a fix.

Front windshield is extremely fragile. The smallest rock will create a chip which will spider across the windshield within a couple days. I have an older Land Rover and there have been more rocks with only a few small chips and no spider. Cheap glass installed on the new Land Rovers.

Took my car to the dealership to have the windshield replaced due to a rock chip. Driving home on the freeway with the new windshield installed, I noticed a new crack moving across the windshield. I had on driven only 45 miles. Contacted Landrover and was told it was just an unfortunate chance event. I previously had a windshield replaced for the same reason. I now need my 3rd windshield in 1 1/2 years

I am reporting a suspected systemic safety defect involving premature failure of the integrated LED daytime running lights (DRLs) on 2020–2026 Land Rover Defender (L663) vehicles. The DRLs reportedly fail at relatively low mileage, frequently around 50,000 miles, during normal vehicle operation. The suspected cause is overheating and premature deterioration of the integrated LED driver electronics due to inadequate thermal management. The precise cause requires investigation. This failure eliminates an important daytime vehicle conspicuity feature, reducing visibility to approaching motorists, pedestrians, and cyclists, particularly during rain, overcast weather, and transitional lighting conditions. Some owners report no dashboard warning when the DRLs fail, potentially leaving drivers unaware of the malfunction. Jaguar Land Rover has known about this issue since at least 2021. Its Special Service Message SSM 75479 specifically acknowledges DRL failures on 2020–2021 Defenders and documents an engineering investigation. Similar failures have subsequently been reported by owners of later model years, suggesting a potentially unresolved design defect. Because the DRL electronics are integrated into the sealed headlamp assembly, dealerships generally require replacement of the entire assembly, costing approximately $3,000 per headlight or $6,000 for both. Land Rover reportedly provides goodwill replacements selectively while requiring other owners to pay out of pocket. I request that NHTSA investigate the entire 2020–2026 Defender population, examine JLR’s engineering records, warranty claims, component failure rates, and headlamp design revisions, and determine whether a safety recall and manufacturer-funded corrective action are warranted. This is a recurring failure of a factory-installed safety-related lighting system, not simply an ordinary maintenance or warranty concern.

I own a 2023 Land Rover Defender 110 X. The passenger-side daytime running light halo is completely inoperative. On November 2, 2026, an authorized Land Rover dealer inspected the vehicle and advised that the entire passenger-side headlamp assembly must be replaced. The quoted repair cost was approximately $3,255, plus applicable taxes and fees. The dealer also advised that the vehicle cannot pass Hawaiʻi’s required safety inspection because of the lighting failure. The original headlamp has not yet been replaced and remains available for inspection. There has been no crash, fire, injury or death associated with this failure. I believe the DRL has failed prematurely on a relatively new vehicle. Because the DRL is integrated into the sealed headlamp assembly, the failure requires replacement of the entire assembly rather than an individual bulb or serviceable lighting component. I am concerned that this premature exterior-lighting failure reduces the vehicle’s daytime visibility to other drivers and prevents the vehicle from passing its required safety inspection. I am submitting this complaint so NHTSA can document the failure and evaluate whether similar DRL failures are occurring in other Land Rover Defenders.

The DC/DC converter failed causing the generator not to charge. This caused the car to lose all power whilst I was driving the vehicle and come to a complete stop on an active road.

The contact owns a 2023 Land Rover Defender. The contact stated that while driving 35 MPH with no other vehicles or objects nearby, the Forward Collision Avoidance system activated with the Automictic Emergency Braking function drastically slowing the vehicle nearly causing a crash. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 13,000.

While driving the vehicle warnings alerted me that the battery was low and to start the vehicle ( it was running as I was driving) then the alert changed to pull over when possible. At this time the power steering and power brakes started to fail by the time I pulled into a parking lot the vehicle completely died and I had to push it into a parking spot. I called Land Rover they towed it to a dealership. The dealership in Orlando Florida said that the DC to DC converter failed and that it would need a new one (but the part is on a back order because it’s a common issue and they have no idea how long it will take to get the part) it will take at least 30 days or more to get a new part. Before I managed to pull over in a safe location the steering became very heavy and the brake pedal got very hard and barely stopped the vehicle ( almost had a collision) and steering into the parking lot was extremely difficult.

Steering wheel is locked and does not turn the wheels

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.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle experienced an electrical fault and shortly after receiving the warning on the dash, the vehicle completely lost power in the middle of traffic. The dealership has told me that the hybrid battery and DC converter both need to be replaced, but the DC converter is on indefinite back order. Based on information I’ve learned from others and I’ve heard from the dealership, Land Rover has been aware of this issue for about a year, but parts have been unavailable for several months. My dealership alone has several of the same vehicle suffering from the same problem, get Land Rover seems to have no path towards resolution.

I have a 2023 Land Rover Defender 90. The instrumentation lighting auto adjusts on its own sometimes causing a hazardous situation. The issue is at dusk when the instrument panel goes haywire and will dim to almost completely dark making it illegible. This is a common issue reported by owners of Land Rover Defenders. 2019-current. This needs to be fixed!

The Tow Hooks are rusted and part of the vehicle when purchased and not an add on aftermarket part or accessory. Land Rover has failed to follow up after many attempts to contact and resolve. This should be covered under the rust and corrosion warranty, and they are ailing to even look at the problem. The concern is if there's any additional rust to major suspension or body parts as well as requesting that these tow hooks parts be replaced/repaired under the 4 year/50,000 mile warranty.

Airbag warning light is ON. Dealer states that this is caused by the wire harness under the seat getting caught when seat moves and breaks the wire continuity. Dealer states that several of these incidents have been observed in many vehicles as the harness design is prone to being trapped in the seat movement mechanism. Dealer states that the passenger side Airbag will NOT deploy if harness not replaced. Dealer states that this Airbag fault is not currently part of the known Airbag recall as that recall is for the driver side Airbag fault due to corroded terminals.

While driving the dashboard suddenly showed a message saying Battery Charging Fault error” a few minutes later the car stopped driving while I was on a busy freeway. It had no power and it displayed several messages saying suspension system is disabled, battery issue, cameras disabled. I had try to navigate my rolling car to a side lane to call roadside assistance. It was a very dangerous incident and needs to be addressed. Land Rover in White Plains NY, diagnosed my vehicle saying the Dc to Dc converter needs to be replaced and they don’t have any in stock. They also mentioned they have 30 customer cars all waiting for the same part. This was scary and I’m grateful my children were not in the vehicle at the time.

Took the vehicle out of the garage, drove 3 miles to the highway, got on the highway, traveling 65MPH, within 15 minutes of leaving home and no more than 5-10 minutes on the highway, the passenger rear tire blew out without warning, I did not hit any debris in the road. The vehicle veered with the sudden loss of pressure, no accident but occurred during rush hour. There were OEM on a 23.5yr Land Rover Defender. Continental CrossContact 275/45 R22
