Land Rover Discovery 5 (L462)

The fifth-generation Land Rover Discovery (L462), launched in 2017, represented a radical shift for the model, abandoning the boxy design of its predecessors for a more aerodynamic, "lifestyle" silhouette. Built on a lightweight aluminium architecture shared with the Range Rover, it shed nearly 500kg of weight, offering a significant improvement in both fuel efficiency and handling agility. In the UK, it remains the ultimate seven-seat family workhorse, prized for its immense interior versatility, class-leading towing capacity, and genuine off-road capability that its more urban-focused rivals struggle to match. However, the L462’s reputation for reliability has been early on marred by high-profile build quality and mechanical concerns. Most critical is the risk of catastrophic crankshaft failure on the 3.0-litre SDV6 diesel models, a failure that can lead to a total engine replacement. The vehicle is also notorious for water ingress, with poorly bonded windscreens and leaking tailgate seals being common UK issues that can trigger a "cascade" of frustrating electrical glitches. Additionally, models equipped with the 2.0-litre "Ingenium" diesel engine are prone to premature timing chain wear and oil dilution if not serviced more frequently than the official manufacturer intervals. When buying a used L462 in the UK, a professional Pre-Purchase Inspection (PPI) is highly recommended to identify hidden issues with the windscreen seal or engine health. Prospective owners should look for cars with a documented service history that shows oil changes every 8,000 to 10,000 miles, rather than the official 21,000-mile intervals. It is also important to test all electronic functions, including the motorized seat folding system and the Pivi Pro infotainment (on later models), and to check the boot and footwells for any signs of dampness. For those seeking the best balance of performance and reliability, the 3.0-litre SDV6 is the most sought-after choice, provided its maintenance history is impeccable.
