NHTSA lists 6 safety recalls and 20 owner complaints for the 2020 Land Rover Discovery. Most complaints involve electrical system (9) and structure (4). The EPA rates it 18–23 mpg combined.
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2017-2020 Land Rover Discovery vehicles. The UniLatch Keyless Vehicle (KV) entry function may fail to properly latch the rear passenger doors, which can result in the doors opening while driving. In addition, the instrument cluster open-door warning light may fail to alert the driver of this condition.
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2021 Range Rover, 2022 Range Rover Sport, 2020-2021 Range Rover Velar, Discovery Sport, 2020-2022 Discovery, and Defender vehicles. The seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly.
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2020-2021 Land Rover Discovery vehicles. A loose contact between the battery ground stud and the chassis may result in various electrical faults, possibly causing a loss of electrical power or the vehicle to shut down while driving.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“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.”
