The DC/DC converter went out. While driving [XXX], all the warning lights came on, no abs, no front collision warning and all other safety warnings lights flashed. Immediately after the lights came on vehicle completely shut down while driving leaving me stranded in the street in Greenwood, AR. I had my vehicle towed to the dealership. Land Rover was already aware of the DC/DC converter issue but told me it was the battery which I paid to have replaced. I drove my vehicle home from the dealership. After arriving home my vehicle would not lock. I contacted the dealership and was advised to bring it back in when they had an appt in 3 weeks. I could not drive my vehicle due to not being able to lock it. While driving the vehicle to the dealership to get repaired because it would not lock, my vehicle shut down this time leaving me stuck in a blind spot on a rural highway (55mph speed limit) with no where to pull over due to deep drainage ditches on the shoulder. For two hours I had to wave at vehicles letting them know there was a dangerous hazard in the road (my vehicle) while waiting for the tow truck. My vehicle was again towed to the dealership, 126 miles away. It was at this time I was advised by the service advisor later confirmed by the General Manager, Land Rover had an ongoing problem with the DC/DC converters. My vehicle has been at the dealership since February 9, 2025 because they do not have the DC/DC converter available. The dealership does not provide loaner vehicles. I have since researched the internet and found numerous articles and other complaints regarding the DC/DC converters going out in Land Rover vehicles.

While traveling at highway speeds, the vehicle suffered a sudden and total loss of motive power (high-speed stall) without prior symptoms. A "Charging System Fault" message appeared seconds before the engine and all critical electrical systems shut down. This failure occurred in active traffic, resulting in the immediate loss of power steering and electronic braking assistance, creating an imminent collision risk for the occupants and surrounding motorists. Component Failure: The authorized dealer confirmed the failure of the DC-DC Converter (original part LR176476), which regulates the 48V-to-12V charging cycle. The component is currently held by the dealer and available for inspection. The failure caused a secondary total depletion of the 12V battery, rendering the vehicle's safety lighting and hazard signals inoperable. Manufacturer Awareness: The dealer confirmed the original part has been discontinued and superseded by a revised design (Part 433123472) due to known defects. Furthermore, the dealer stated that multiple other vehicles are currently grounded at their location awaiting the same backordered safety component. There is currently no estimated time of arrival for the revised part, leaving the vehicle indefinitely sidelined due to a systemic manufacturing flaw.

Vehicle: 2012 Range Rover Sport Supercharged (VIN: [XXX] ) Recall Campaign: N623 / the federal safety agency 21V635 Incident Description: In October 2025 I had a recall repair done at Land Rover Annapolis. I picked up my vehicle from Land Rover Annapolis after the N623 Fuel Outlet Flange Recall was performed. Immediately after service, while driving in a live lane of traffic, the vehicle unexpectedly stalled, resulting in a complete loss of motive power. The dashboard fuel gauge falsely indicated 55 miles of remaining range, but the vehicle had actually run out of fuel. This indicates that the fuel sending unit/float assembly was improperly reinstalled or damaged during the recall service, creating a secondary safety defect. I figured it would calibrate and fix itself. When the dealer reached out after my service appointment I made them aware of the issue. No one contacted me. I contacted Land Rover corporate when it continued to happen and was told to bring it back to the certified repair location. The dealership took 16 mins to look at my vehicle and deem the engine bad. Give a ballpark quote of 20000 to 30000 dollars to replace the engine. Despite this life-safety event, the dealership refused to pull stored Diagnostic Trouble Codes (DTCs) and is attempting to deflect liability by blaming a pre-existing minor coolant leak that never triggered an overheat warning. I am reporting a failure of the recall remedy and requesting an investigation into the dealership's refusal to diagnose consequential damage (High-Pressure Fuel Pump failure) caused by the botched safety When I brought up the fact that they should have diagnosed the codes already he offered to have them run it for free tomorrow like he was doing me some kind of favor. When I said did I disagreed with the findings based on the fact that there was no evidence of it being the engine overheating due to cool it he replied that maybe I needed a second opinion and it needed to be off of their lot by Friday.

Vehichle completely shut off while driving in middle of road. All power was cut to vehicle, luckily I had foot on the break at the time at a stop light. Was dead in the intersection, required a tow to dealership. The dealer confirmed it was a DC/DC electrical failure that had my mild hybrid engine not working. Basically communication with the gas engine stopped and vehicle died after draining the battery.

The cars electrical system failed while driving on the highway. It first impacted the traction control, then ABS, then put the car into neutral while traveling at 70 mph the highway with no ability to put the car into drive. Fortunately I was able to coast into the breakdown lane before the car completely shut off and put itself in park. Had I not been able to get into the breakdown lane we would have been sitting stalled in the middle of the highway with no flashers p putting me, my wife and kids at significant risk of injury or death with cars and trucks going 70+ mph. The vehicle has been inspected by the dealer and I have been told it is a DC-to-DC converter that has failed and is the cause of the issue. The dealer informed me that this has been a recurring issue for these vehicles and that parts are on backorder due to the volume or orders. At the time of my call they indicated there is a "significant" number of orders nationally for this part. I was fortunate to have been able to get into the breakdown lane but this would have turned out very differently had I not been able to do that. I think others should be warned/aware of this issue.

VIN# [XXX] I reported complaints during all of my routine oil changes that I had a coolant leak and it smelled like something was burning under my hood. I also told them that I had coolant on my garage floor and that my gears were stalling on my vehicle. I reported these issues when my car had under 10,000 miles and again at the 20,000 mile range. They stated they saw no issues or related recalls. I believe I was intentionally lied to because my car was under warranty at the time and they didn’t want to address the issues. I asked for them to check again prior to the expiration of the factory warranty they said they found nothing. I now have 69k miles and the issues that I’m experiencing surely didn’t happen over night/ Recently when my oil change light came on another light came on as well. I asked the dealership to look into it but they refused unless I paid $265. I went to another repair shop and the identified several issues (codes) PCM issues that would explain the issues that I reported over the years and none of the recalls were looked into. I purchased my car new during Covid and did not have a lot of face to face contact so I thought I purchased the extended warranty and now realize that I did not. I have reported these issues well before the end of the warranty period and believe that my car should be inspected immediately because I now fear for my safety and the safety of my family. I now have the following codes showing on my vehicle: Engine P00B0-49 June 7, 2025 11:16 AM P3498-86 P2170-11 P21A0-84 P21A1-84 P219F-84 U0080-87 P26CB-72 Turbocharger/Supercharger Boost Control B Module Performance Internal Electronic Failure Cylinder 1 Deactivation Performance Signal Invalid Exhaust Pressure Regulator Vent Solenoid Control - Circuit Low Circuit Short To Ground Cylinder 5 Air-Fuel Ratio Imbalance Signal Below Allowable Range Cylinder 6 Air-Fuel Ratio Imbalance Signal Below Allowable Range Cylinder 4 Air-Fuel Ratio Imbalance Signal Below Allowab INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

I reported issues with my car stalling, front and rear camera going blank and smoking under my hood, in addition leaking coolant. I immediately requested for the dealership to inspect the vehicle and I smelled coolant and saw the coolant on my garage floor the dealership stated they did not find anything. This occurred during my first oil change at around 6,000 miles. It happed again at the second one as well. I had the same issue when I got my oil changed amongst other issues no issues detected. I went to the dealership to get an oil change and the code P00B0-49 was showing the dealership asked if I wanted to pay $265 to diagnose the vehicle I stated I would not because these issues didn’t happen overnight and there could be potential recalls not addressed when they should have been.
