ELECTRICAL SYSTEM
Car only has 42K miles on it- we were driving down the highway at approx 75mph, when the dash alarms started going off indicating an electrical system failure. A few minutes later all systems started flashing failures (lane keep assist system, braking system, etc)....then suddenly the gear box system failure alerted and the gears disengaged, the RPM's shot up and red-lined, and the CAR lost power in the middle of the highway. Fortunately we were able to get off to the shoulder without getting hit by a semi-truck. The car was completely dead. It had to be towed to a dealer, to find out that the DC/DC converter had failed- and these parts have been on back order for months- apparently this is a common issue with these cars, and people have been talking about it online...many have been without their car for 3-4 months waiting these parts.

The car completely died. Unable to be jumped. Had to be towed. There’s a problem with the DC/DC converter. The parts going to take at least 3-4 weeks to come in. My dealer states they have over five or six vehicles waiting for the same repair. This should be a recall issue!

ELECTRICAL SYSTEM
On December 29th 2025 my car displayed an alert "Electrical Fault Detected: Please Pull Car Over Safely". I was in rural New Hampshire at the time so continued driving (for about 5 minutes) until I lost all power steering, stability controls and ability to drive the car - luckily by this point I had made it to Gorham, NH. Luckily it was just me in the car and not my family as the temps were below 10 F that day and Land Rover couldn't get a tow until the next day. Since then the car had to be towed to Land Rover Bedford and has been in the shop since as they dont have any DC Converters (Part number 433123464) in the US. Apparently there are 1400 Land Rover Defenders all sat in garage lots as nobody can get this part in the US from the manufacturer. There is no ETA on when the part will arrive in the US and I will have my car back.

The vehicle was not repaired because the part was on backorder. The manufacturer was not contacted. The approximate failure mileage was 61,000.

FUEL/PROPULSION SYSTEM
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.

ELECTRICAL SYSTEM
The Defender is only 2 years old, with 59k miles. Outside of warranty. It is a mild hybrid. Received an emergency electrical fault issue. Car stalled out. Had to get it towed to dealership. Its been with the dealership for a month now, with another month anticipated for the part, a dc converter, which is on backorder with LR to be delivered. Battery is dead also. Total repair is estimated at $3100. I will be without the vehicle for atleast 2 months. Looking through the internet it appears this is an issue with LR. Filed a complaint with LR corporate. They are aware of this happening also to vehicles which would explain the backorder on the part. No recall yet however.

ELECTRICAL SYSTEM, ENGINE
My car died on December 14, 2025 when I was pulling out of my driveway. It read “stop safely electrical fault detected.” And then shut down and would not turn on. Then it said “battery low. Please start engine.” But the car would not start. I had to get it towed to the dealer. They told me it was a the DC converter or the epic module. They said this is a company wide issue with the 2023 defenders and they do not have the part in stock and that it is on back order. Right now they are stating that the part may be in in mid February. Previous to this issue I also had issues two times with my car stating engine coolant issues and had to bring it to the dealer two times to get fixed.

ENGINE
we had a coolant leak like the one reported on recall N785, I called the Land Rover USA office and they said that they only have a "voluntary" recall for this problem and I need to pay for them to fix it. It's not faire that they refuse to fix something that is happening in the same car and model but different engine type. They know they need to recall all the Defenders. What you can do to protect us?

ENGINE
1.) Coolant turbo lines leak coolant. Causing the engine to overheat. It is recommended by the dealer to replace the two(2) o-rings and bypass hose assembly. 2.) This is a high risk this can cause risk of an engine fire in addition to major damage to the engine. 3.)The Land Rover Dealer (Annapolis, MD) has confirmed that this is a known issue. Further research online confirms from other customers with dealers that this is a known issue. 4.) The dealer performed diagnosis on the vehicle and confirmed the parts that need replacing. 5.) As the engine gets close to overheating, you notice the temperature gauge moving to red and a warning message that the engine is overheating. Initially, you will notice messages that the engine coolant level is low and as the problem progresses, you will see the message more frequently. I have personally gone through two full bottles of antifreeze in a day. The cost of repair is over $2500.

The door actuators are failing which is a very common problem on these vehicles. This fault makes it impossible to lock the doors and arm the vehicle. This is a significant safety issue. Based on the widespread complaints it seems reasonable that Land River should rectify the problem

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

VISIBILITY/WIPER
The windshield is very prone to splintering, chips and cracking from even small roadway impacts. I have had to replace the windshield twice in the last 6 months. This has been an ongoing problem with Defender 90 windshields from what I can read and the manufacturer is very aware of it. The windshields pose a danger to the driver at worst and an ongoing and expensive maintenance expense at best.
