Land Rover Range Rover IV (L405) (2012 – 2022)
Reliability score : 5.2/10
The fourth-generation Land Rover Range Rover (L405) marked a technical revolution upon its launch in 2012 thanks to the adoption of a 100% aluminum monocoque structure, allowing for spectacular weight savings (up to 420 kg depending on the version). Positioned as the pinnacle of the luxury SUV, it combines limousine-like comfort with extraordinary off-road capabilities (Terrain Response 2 system). A major facelift occurred in 2018, introducing the dual-screen Touch Pro Duo infotainment system, Matrix LED headlights, and the plug-in hybrid powertrain (PHEV P400e). While its road performance and refinement are exceptional, its overall reliability remains its Achilles' heel, with recurring electronic failures and serious mechanical weaknesses on certain engines, notably the diesel V6s.
✅ Strengths
- Imperial ride comfort (standard air suspension)
- Unmatched off-road capabilities in the category (Terrain Response)
- Soundproofing and material quality (leathers, woods, aluminum)
- Space on board, particularly on LWB (long wheelbase) versions
- Driving pleasure of the diesel V8 (SDV8), rare and torquey
⚠️ Weaknesses
- Very temperamental overall electronic reliability (screens, sensors, modules)
- Frequent and documented engine failures on the 3.0 V6 Diesel (TDV6/SDV6)
- Astronomical maintenance, repair, and insurance costs
- Substantial weight leading to rapid wear of brakes and tires
- Steep depreciation, particularly on older diesel engines
🎯 Verdict
The Range Rover L405 is a paradoxical vehicle: it is undoubtedly the most majestic and versatile SUV of its generation, but its reliability is unworthy of its rank. Buying a model equipped with the 3.0 V6 Diesel (TDV6/SDV6) is an extremely risky gamble due to frequent crankshaft failures. If you want a diesel, favor the robust 4.4 V8 (SDV8) or the recent Ingenium inline 6-cylinders (post-2020). The petrol versions (V8 Supercharged) are mechanically more solid but require meticulous maintenance of the cooling system. Golden rule: never buy this vehicle without a complete, transparent maintenance history, and ideally covered by a solid mechanical breakdown warranty (such as Land Rover Approved).
