Component/System: 48V Mild Hybrid Electric Vehicle (MHEV) system including the DC/DC Converter (subject of active recall D126), Battery Energy Control Module (BECM), Telematics Control Unit (TCU), Battery Charge Control Module (BCCM), and Vehicle Immobilizer Module (VIM). All components are available for inspection upon request. What happened: My 2021 Range Rover Sport HSE MHEV (VIN: [XXX] ) experienced a complete no-start condition after sitting for approximately one week. Prior to towing the vehicle to Hendrick Jaguar Land Rover Charlotte, I performed a live data diagnostic using a Land Rover specific iCarsoft LR V3 diagnostic tool which confirmed the 48V hybrid battery at 17.86% state of charge critically below the minimum threshold required to authorize a start sequence. The TCU, BCCM, and VIM all showed not fitted simultaneously a known cascade effect of a critically depleted 48V MHEV system. Recall D126 for DC/DC Converter failure was confirmed on my vehicle. The DC/DC converter manages power transfer between the 48V and 12V systems. Its failure directly caused the 48V battery depletion and subsequent cascade module failures. Safety risk: The vehicle became completely immobile with no warning. The immobilizer went offline preventing the vehicle from starting, stranding the occupant in a parking lot. A vehicle that shuts down without warning and cannot be restarted poses a serious safety risk to the driver and other road users. Additionally the DC/DC converter failure affecting the MHEV system represents a risk of sudden loss of hybrid assist during driving.

Vehicle was operating normally on interstate traffic at 70mph when vehicle suddenly flashed "Charging system fault" and the vehicle then would not accelerate and dropped to 25 mph. Trying to exit the interstate and vehicle went into limp mode and battery icon showed up. Had to be towed to Range Rover dealership Range Rover said the issue was a DC / DC converter. They replaced this and are now saying the BISG alternator is at fault. Repairs will be close to 8k without a confirmation this will be the fix. Not comfortable driving the vehicle even with the 'fix." A vehicle "Dying" on the interstate at interstate speeds is dangerous. The problem is known on the internet and by range rover. Not sure if component has been inspected. 2021 Range Rover Sport 53k miles

The alternator on my vehicle (DC to DC convertor) went while driving home with only one sensor prompting me to turn back around and head home to be safe. The car essentially died and power steering was lost. There were no prior warnings or indicators of an issue. I had 15 minutes to make it back home. The car died in intersection, luckily at corner of my street and folks had to help push it into the driveway. Having searched for a replacement, there are no after market options, no used options, and my mechanic was told we are customer 30,335 as THOUSANDS of owners are experiencing this very same problem. The estimate weight time for the part was 3 months, at the least. So, we are stuck with an invaluable car, sitting for three months, and forced to pay storage fees at the mechanic shop as well as keeping current on the monthly car payment.

Over the last few months my warning light for engine coolant appears and says add coolant now. I will add coolant at preferred vendor. Two weeks later my coolant light will appear again saying add coolant now. When I looked myself after that 4th occasion I saw that the coolant tank was in fact empty and my car was not experiencing a sensory or electrical issue. As far as electrical my car volume will turn up and down on its on at sporadic times. I have had a professional take a look and not one service technician mentioned that I may have a possible leak or electrical problem . They just fill my fluids. However, I am certain there is a leak since my tank is empty almost every 10-14 days and my warning light is coming on to verify. I will be going back to land rover for them to do a more thorough inspection.

I was driving the car on March 11th 2022, at around 10pm when the car suddenly lost power, while driving in a rural area of Interstate 5 in northern California when the vehicle lost power, I was unable to see anything at all and had to pull to the shoulder unsure of what was on the shoulder. Dash display stated "headlight detected" and the vehicle shut off. Everything was off including, power, lights, engine, and the vehicle was unresponsive for 30 minutes. After about 30 minutes, the car started up and I decided to drive it. Furthermore, after about 1.5 miles the issue repeated and the car shut off again. Car was off for about 5 minutes, at this point I decided not to drive the car as I felt it was dangerous. The night of March 11th, the vehicle was towed to the nearest Land Rover/Range rover dealership and was diagnosed on Monday the 14th. The dealership diagnosed the vehicle with a defective battery. The battery was replaced and I was assured that the technician was certain the issue is resolved, and they have experienced it with other Range rover sports in the past year. I picked up the vehicle on March 16, 2022. Today, March 19, 2022, while driving the vehicle around 1pm the vehicle, the dashboard displayed “headlight fault detected” and the vehicle was once again shut off, including all the electronics. I do not consider this incident to be as dangerous as it was during daylight and near my house. However, the earlier incidents were very hazardous as it occurred at night, with no vehicle lighting or street lighting in an unfamiliar area. I am not confident driving this vehicle at all, as it could lose power at any moment. Thankfully in this time, the vehicle was in a safe area, but this incident could certainly have happened in the middle of a turn, in an area with no shoulder, or in a construction zone. All of which would dramatically increase the risk of significant injury.
