NHTSA lists 4 safety recalls and 37 owner complaints for the 2018 Land Rover Discovery. Most complaints involve electrical system (8) and power train (8). 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 2018-2020 Range Rover, Range Rover Sport, Discovery, and Range Rover Velar vehicles. The Auto High Beam (AHB) system does not indicate through the instrument cluster when the high beams are illuminated automatically. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2017-2018 Discovery vehicles equipped with low line headlight assemblies. When towing a trailer with the trailer lights connected to the trailer socket and the vehicle's Daytime Running Lights (DRL) are on, the trailer lights may not function.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Shortly after I purchased this used 2018 Land Rover Discovery with approximately 30,700 miles, the vehicle began intermittently lurching, surging and shaking during normal driving. These symptoms began before the check-engine light illuminated. Two days after the check-engine light first appeared, the lurching and surging became noticeably worse. Approximately two minutes before the first engine shutdown, numerous warnings appeared in rapid succession, including “Stability Control Not Available,” “Forward Alert Not Available,” “AEB Not Available,” and “ATPC Not Available.” I stopped the vehicle briefly. Approximately one minute after resuming driving, the engine unexpectedly shut off and the vehicle remained disabled for approximately 30 seconds before restarting. The abrupt loss of propulsion nearly caused the vehicle behind me to collide with the rear of my vehicle. During the second incident, the engine suddenly shut off while I was making a left turn through a four-way intersection. The vehicle became immobilized in the middle of the intersection, directly exposed to opposing oncoming traffic, and would not restart for approximately one minute. The sudden…”
“Pulled out of car wash to drying area. Car was still in D, with foot on brake. After a few moments, auto start/stop triggered shutting the car off, but rotary gear selector retracted while still in D. Would not allow restart as trans still in Drive and dash displayed Gearbox malfunction. After a 15 minute wait for system restart, tried to start to no avail. Had to get Discovery towed to dealer which informed that gear selector failed and needed replacement. Thank goodness I wasn't in a traffic situation. This problem has recalls on other models in same model year. Desire the Discovery (D5) to be included in recall. Car is at 82K miles.”
“This vehicle has an active water intrusion from the headliner above the windshield due to windshield bonding and body seal failure. Water is dripping down and entering the dashboard area and shorting electrical control modules behind the media/glove box and media console. Each time the media/glove box is opened, the HVAC system shorts and forces the defrost system to activate involuntarily. The vehicle also exhibits Park Brake Fault warnings, delayed and intermittent no-start conditions, brake fluid loss, and electrical instability. This is an active electrical short inside federally regulated safety systems, making the vehicle unsafe to operate. The defect is progressive and continues to worsen”
