Land Rover Discovery Problems — All Years, Common Issues & Reliability

I purchased my 2024 Land Rover Discovery new in March of 2024. In October of 2025, I found a large amount of water leaking through my windshield. Land Rover had my vehicle from October 2025 until April 2026. When it was returned to me it had mold in that had to be remidate3d and now my screen is starting to short. I am concerned of the safety of this vehicle and the amount of water that went into the electrical system.

The DC/DC converter had failed after the recent software upgrade by JLR right in the middle of the road. Barely made to their shop. It has been a month since. No updates on the status of the fixing my car. Had call many times, no response. The car is in the JLR diller in Hunt Valley, Maryland.

Our DC converter caused an electrical malfunction which is apparently such a big problem that our dealership can not get the necessary parts to fix the problem. We are being told we are number 21 in line.

The contact owns a 2022 Land Rover Discovery. The contact stated that while driving at an undisclosed speed, the vehicle jerked, and several unknown warning lights were illuminated. The vehicle was pulled over to the side of the road and turned off. The contact waited before restarting the vehicle; however, after driving for several miles the failure reoccurred. The contact stated that on a separate occasion, the vehicle jerked, and the vehicle failed to accelerate as intended while depressing the accelerator pedal before the vehicle stalled. The message "Emergency Braking Assistance Not Available" was displayed. The contact was able to coast to the side of the road. The contact called for assistance and another driver arrived the scene and followed behind the vehicle back to the residence. The vehicle was taken to the dealer, where it was diagnosed that the ground studs were not connected and had failed to function as intended. The vehicle remained at the dealer unrepaired. The contact stated that before the electrical failure, the message "Check Coolant" was displayed. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 21V457000 (ELECTRICAL SYSTEM); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 76,000.

DC/DC converter failed (January 2025) and is sitting at the dealership. My vehicle completely shut down while I was driving on the interstate. I had the same issue in April 2024 and was without my vehicle for nearly 2 months.

Windshield was leaking into electrical compartment. Caused $10,000 worth of damage and caused the vehicle to be inoperable and stop while driving.

DC DC converter failed while driving. Car shut down and rolled to a stop. Could jump start the car but would only work for 10 seconds or so to move it out of traffic. 1-2 month part delay.

Car displayed a warning noting of an “an electrical fault” but was still running fine otherwise. Drove straight to service center roughly 5 miles away. About a half a mile away from service center the car experienced a cascading number faults in quick succession. First it was safety systems, then air suspension, followed by transmission and finally steering, which point the car was able to roll and some steering though required significant effort. This occurred during traffic, where luckily i had just gotten off the highway. I was able to coast the car into the middle of a shopping center parking lot where it became immobile. A fortunate timing of intersection traffic lights being green likely helped avoid a collision or hitting a pedestrian as all vehicle systems shut down. Towed vehicle to factory service center. Dealer confirmed a a failed DC-to-DC Converter (48V to 12V in mild hybrid system) led to vehicle shutdown and damaged auxiliary 12V battery. Requires a new DC to DC converter but is on backorder for weeks with no ETA available. Car remains immobile until a new part is received.

The DC-DC converter went out in December. The vehicle has 53,000 miles on it, so it is just out of warranty. I live 100 miles from the nearest dealership so I had it towed to a local shop. I was originally told the part was on back order until Mid-February. I was told yesterday, they think it may not be available until May 2026. If this is such a big issue that they can not keep up with the part, why is this not a recall item?

I was driving on Ware Rd about 50 MPH on my way home. The vehicle turned off while I was driving and had to turn into a street before the vehicle stopped moving. There were no warning lamps, messages or other symptoms prior to the failure. If I had been on a highway, there would not have been a way for me to get out of dangerous traffic. The dealer checked the vehicle and determined that it had suffered a catatrophic engine failure. They had no explanation on the cause of the problem. My vehicle had just run out of warranty with only 60,000 miles on it.

3rd time the vehicle has experienced a electrical fault and renders the car undrivable and will shut down while driving regardless of where you are. Each time the vehicle has stopped while driving on an interstate.

JLRNA has identified my vehicle as unsafe to drive due to bonding delamination of the front windshield. As a result, the windshield had water egress. The service department has deemed my vehicle unsafe to drive as the windshield may not be properly bonded to the vehicle body, allowing it to loosen or detach during a crash. I am aware of multiple vehicles, including mine, currently waiting for replacement windshields at the dealership with no known ETA for replacement or repair of the windshield. This is a historical issue that JLRNA was ordered to resolve, as previous incidents were due to a manufacturing deviation in primer and bonding agent application.
