Defect summary: repeated water intrusion (windshield, roof rails, rear door latch) leading to electrical damage. Electrical failures resulting in sudden loss of power, lighting, and infotainment. Critical safety system failures including: sudden loss of steering assist and brake assist while in motion. Vehicle stalling with the engine running but no drivetrain response. Gear shifter malfunctions leaving the vehicle stuck in gear. Notable incidents: July–August 2025 (61,000 mi): multiple events of complete power loss while driving, including loss of steering and braking control on a public roadway. September 11, 2025 (post-repair): after dealer-replaced battery and gear-shift module, the vehicle failed catastrophically within 450 feet of leaving the service center, jolting violently, losing all electrical power, and leaving steering and brakes stiff. An edison police officer witnessed the event and assisted in traffic control. Safety concern: these recurring failures present a clear and ongoing danger of crash, injury, or fatality. The pattern demonstrates a systemic design or manufacturing defect related to water ingress and electrical integrity.
The contact owns a 2020 Land Rover Discovery. The contact stated that while driving at various speeds, the navigation system screen went blank. the vehicle randomly failed to start. The Land Rover logo was on the screen. While driving, the battery warning light was flashing. All the warning lights were illuminated.

Vehicle warning lights come on including traction control and engine warning. Vehicle stops running after halting and then quits running completely. I had the vehicle towed 80 miles to the nearest dealer in columbia, SC they reported that it was a loose ground wire on the battery and told me it was resolved. Less than a month later the same thing happened again and all 4 wheels locked up requiring the towing company to drag it onto the flat bed two truck. It was towed to the local dealer in hardeeville, SC for repair last Friday and am waiting on a notice that they are working on the vehicle. I did report the issue to the local dealer prior to the latest event and was told that the earliest available appointment was a month out. I was not told of any recall by either dealer but was told that they are having the same issue with “so many cars” the first event was on September 13th and the second on October 14th.
