What 2023 Land Rover Discovery owners say
Most recent owner complaints, unedited.
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.
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.
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?
Perrelli Scorpion 255/55R20 tires experience experience excessive wear down to cords in under 15K miles. Tires are in adequate to support the weight of the vehicle.
I am writing to report a safety issue with my 2023 Land Rover Discovery Metropolitan that occurred on April [XXX] 2024. VIN: [XXX] The issue involved the steering wheel locking unexpectedly. After parking the car overnight for 15 hours, I returned to find a message indicating lane departure assist wasn't working, and the steering wheel was completely locked and inoperable. I attempted various troubleshooting steps, including changing driving modes, restarting the car, and checking for software updates, but none resolved the problem. While the car functioned normally in terms of forward and backward movement, the locked steering wheel prevented any turning ability. There were also no warning lights or error messages displayed on the dashboard. The only solution I found was to perform a hard reset by disconnecting the negative battery cable for 3 minutes and then reconnecting it. It's concerning that a similar issue appears to be reported by other Land Rover owners online, particularly with Defender models. [XXX] My primary concern is the possibility of this malfunction occurring while driving, which could lead to a serious accident. There seems to be no guarantee that this isn't a potential risk. I will be in contact with the Land Rover dealership locally and urge the federal safety agency to investigate this potential safety concern with Land Rover vehicles. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I was in a parking lot adjusting settings via the touch screen when the vehicle suddenly deactivated the key fob rendering the vehicle useless. The only option was to get the spare key to start the vehicle. This presents a safety issue for all occupants if the vehicle is disabled because of a malfunction with the key, potentially leaving people stranded in a unsafe environment.
