The fourth-generation Land Rover Range Rover (L405) marked a major technological turning point upon its launch in 2012. As the world's first SUV featuring an all-aluminum monocoque structure, it shed up to 420 kg compared to its predecessor (L322), thereby improving its road handling and efficiency. Facelifted in late 2017 (2018 model year) with the integration of the Touch Pro Duo infotainment system and the introduction of plug-in hybrid powertrains (PHEV), it embodies the pinnacle of off-road luxury. However, despite its regal performance, the L405 suffers from the brand's historical reputation: highly temperamental mechanical and electronic reliability. The petrol engines (supercharged V6 and V8) offer exceptional drivability but require rigorous preventive maintenance, particularly re
The Range Rover L405 is a paradoxical vehicle: it offers an unmatched driving experience and luxury, but its reliability is objectively mediocre. If you opt for a petrol engine (V6 or V8 Supercharged), the engine itself is robust, but its ancillaries (plastic cooling components, water pump) are ticking time bombs if not replaced preventively. Purchasing a used L405 should only be considered with a crystal-clear maintenance history and, ideally, an extended mechanical breakdown warranty. Flee from the V6 diesels (risk of crankshaft failure) and beware of the early PHEV models (2018-2019) riddled with bugs.
