Complaints about the 2017 Land Rover Discovery cluster around two main areas: the engine and windshield-related water intrusion. On the engine side, owners describe coolant loss that returns after dealership repairs, with at least one account of the engine shutting off mid-drive after a sudden low-coolant warning. Timing chain failure causing significant internal engine damage also shows up in the complaints. The windshield pattern is notable because it overlaps into electrical territory, owners consistently report water leaking in from the top or passenger side of the windshield and tracking down into the dash, where it triggers electrical problems including instrument cluster faults, warning lights cycling on, and in some cases the transmission getting stuck in gear while driving.

By System
The 2017 Land Rover Discovery has 5 recalls, the most serious involving rear passenger doors that can fail to latch properly and swing open while driving, with a secondary risk that the dashboard warning light may not alert the driver that a door is unsecured.
A separate structural concern also affects the rear doors: they may not catch fully when closed, again creating the risk of an unexpected opening while the vehicle is moving. On the fuel system side, the fuel gauge can misread the tank level and trigger a low-fuel warning when fuel is actually available. This matters beyond simple inconvenience because a driver who believes the tank is empty and the engine stalls loses both drive power and the vacuum-assisted braking that makes the brake pedal feel normal, leaving the vehicle harder to slow or stop. There is also a lighting issue on vehicles equipped with low-line headlight assemblies: when towing a trailer with its lights plugged into the vehicle's trailer socket and the daytime running lights active, the trailer's brake lights and turn signals may not illuminate. Drivers behind a towing vehicle rely on those trailer lights to know when it is slowing or turning, and without them, the risk of a rear-end collision rises.
