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.

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.

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.

The Halo/daylight running light has burned out. I have found on the internet that this is a know issue. Mine burned out at 57,000 miles. The dealer wants over $3000 to fix it.

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.

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.
