2020 Land Rover Discovery problems

“Vehicle suffered a catastrophic failure of the manufacturer-directed safety campaign remedy for Service Action N694 (Windshield Water Leaks). The Vehicle was brought in for service immediately after receiving the N694 Service Action Notification in September 2023. The inspection found no leaks and no action was taken. Two months later, in November 2023, the windshield began leaking water during rainstorms and was immediately brought into the dealership for service. The windshield was repaired, but not replaced which was also a remedy under the Service Action. The windshield again experienced severe leaking in September 2026 during an overnight rainstorm and significant damage to the vehicle has occurred. The dealership's temporary 'topical reseal' remedy completely failed, causing severe water intrusion that corroded the main dashboard infotainment screen module and flooded the vehicle's electrical channels. This hidden factory defect has compromised critical dashboard safety displays, created a toxic mold health hazard inside the cabin, and left standing water under the floorboards.”

“The windshield has failed which allows water to enter the vehicle. It puts me at risk because if I were to drive it in the rain or take it through a carwash it would destroy the electrical systems in the car and leave me unable to view the speedometer, vehicle information. It could also cause the computer in the middle to quit working. I have had the car to the dealership twice already and now it is leaking again- the first time they replaced the windshield because it had been recalled. 15 months later the new windshield began to leak and the dealership resealed the windshield and now 18 months later it is leaking again. The dealership said LR will not do anything and quoted me a "discounted" price of $3,219 for a new windshield or said they could attempt to reseal it again for $1,094 and that if it broke they would have to replace it. The vehicle has around 67,500 miles on it and has never been wrecked. This is a known problem and they are not going to repair the issue.”

“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.”

“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.”

“The contact owns a 2020 Land Rover Discovery. The contact stated that while the vehicle was at the dealer for maintenance, the contact was made aware of TSB: SSM74710 for the windshield seals. The vehicle was inspected under the TSB: SSM74710 (Failed Windshield Seals). The contact stated that on a separate occasion, months after the repairs, water leaked inside the cabin of the vehicle. The water leaked from the top side of the windshield on the driver’s side. The vehicle was taken to the dealer, where it was diagnosed, and determined that the windshield seal had failed. The vehicle was not repaired. The manufacturer was notified of the failure; however, the contact was informed that the dealer performed a windshield seal test, and the vehicle had passed the inspection. No evidence of a water leakage was present. The failure mileage was approximately 46,000.”

“Front parking aid sensors do not alert me to objects in front of me when parking forward. I have to first backup two feet to get it to work, then it picks it up once I put in forward motion again. The dealer stated that they have no recalls for this problem even though my vehicle is in warranty.”
