Renault Koleos II (HZG) (2016 – 2023)

Reliability score : 7.6/10

The Renault Koleos II (internal code HZG) is a D-segment family SUV, based on the modular CMF-C/D platform of the Renault-Nissan Alliance, which it shares closely with the Nissan X-Trail (T32). Unlike its predecessor, it abandons the atypical design to adopt the brand's premium stylistic codes (Talisman-style). Manufactured in Busan (South Korea) by Renault Samsung Motors (where it is sold as the QM6) and in Wuhan (China), it stands out for its generous rear spaciousness and ride comfort, but foregoes a 7-seat version (reserved for the Espace or Nissan X-Trail). Restylings (Facelifts): - Phase 2 (2019): Slight aesthetic tweaks (grille, skid plates), improved interior materials, full-screen Apple CarPlay/Android Auto integration, and a revamp of the engine range (introduction of Blue dCi).

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Renault Koleos II is an excellent used car deal if you target the right engines. Often depreciated compared to its European competitors, it offers an unbeatable price/performance/comfort ratio. For petrol, the 1.3 TCe (Europe) is a very relevant choice, combining modernity and reliability. In international markets, the 2.0 and 2.5 naturally aspirated blocks are indestructible, on the sine qua non condition that the CVT gearbox has been regularly drained. Diesel versions should be approached with more caution, particularly the Blue dCi (1.7 and 2.0) whose AdBlue system is a source of costly breakdowns. Opt for a facelifted model (post-2019) to benefit from a more reliable multimedia system and improved finish.
