2023 LAND ROVER DEFENDER Complaints

The dc dc converter failed and had to be towed away. The incident happened while I was driving the vehicle.

Vehicle was started, while still in park, an alert appeared on the dashboard “stop safely electrical fault detected”. Vehicle was turned off and restarted, with the same warning light on. Called LR dealer, Vehicle was backed out of garage at service advisors advice, parked and flatbed tow truck called.

While driving on the freeway I recieved and elctrical fault detected please pull over when safe. The issue is the DC to DC converter failed resultign in the loss of charging for the car and relaince on stored elctricity in the battery to drive systems. I was on the highway at freeway speeds and had to exit the highway quickly to avoid the vehicle completly shutting down on the freeway. The dealer has verified the issue. There is significant discussion on owner boards about the numerous failures across all years of the mhev defender resulting in owners being stranded on the side of the road. Land Rover needs to issue a recall to replace this defective part.

The contact owns a 2023 Land Rover Defender. The contact stated that while driving at an undisclosed speed, there was white smoke coming from the engine compartment. The message to “Add Coolant” was displayed. The coolant was added to the coolant reservoir; however, the failure reoccurred. The contact was constantly adding coolant; however, there were no coolant leaks found. The vehicle was taken to an independent mechanic; however, the cause of the failure was not yet determined. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced an unknown recall; however, the VIN was not under recall. The dealer was made aware of the failure and informed the contact that the vehicle needed to be diagnosed. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,000.

DC/DC converter failed on the 2023 Land Rover Defender about 2000 miles out of warranty. The parts are on back order with no ETA because so many LR Defenders are having this issue. This can cause your car to die while driving.

The DC to DC converter Failed. It is part of the mild hybrid system. Multiple cars in my state and globally have reported the same failure around the same time. Supposedly these failures are due to the cold weather. At the 1st start up of the day a warning message displayed "Stop safely Electrical fault detected" the it disappeared after 1minute. After the 2nd start up the message reappeared and stayed on. I drove straight to the dealership where the vehicle would not be able to start or move again. My safety and others would have been at risk if the vehicle would have been immobile on the road. The vehicle has since had the DC to DC converter replaced as well as the battery which suffered power drain. These repairs were done by the manufacturer/dealership under warranty. The DC to DC converter was on back order for months due to so may vehicles suffering the same failure. With more cold weather ahead is the replacement part or system safe? I think this issue needs to be investigated.

DC-DC converter has failed causing the car to shut of while driving. During this period of time the car shuts off and the steering wheel locks. Seems to be a massive problem as every dealer we call doesn't have the parts to repair and are quoting months to fix the car.

The DC/DC converter failed when I turned the car on and I received a warning. Drove straight to the dealership to drop it off for service. Reviewing others with this issue online, it is an extremely common problem and no recall has been issued. Many report their cars dying in the middle of nowhere. To make matters worse, there is a long backlog for the part, months for some people. I’m waiting to hear back from the dealer on my wait time. I hope by submitting a report that you will consider requiring Land Rover to issue a recall.

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.

While driving my Defender 130 at Highway speed a warning for a faulty electrical system light came on. Within a mile while I was trying to exit the highway, all electrical systems failed. I had a gearbox failure warning and the car went into neutral at highway speed. Power steering failed and I had to manhandle the vehicle off the road into a snow drift to get off the highway.
