Renault Scenic III (JZ) (2009 – 2016)

Reliability score : 8.2/10

The Renault Scénic III (codename JZ), available in short-wheelbase (5-seater) and Grand Scénic (5 or 7-seater) versions, marked a major turning point for Renault. After a Scénic II with disastrous reliability, this third generation was designed with rigor in mind (Renault Quality plan). It went through three phases: Phase 1 (2009-2012), Phase 2 (2012-2013, new front end and 'Energy' engines), and Phase 3 (2013-2016, grille with large logo and R-Link system). It is a benchmark compact MPV, offering an excellent comfort/road handling compromise. On the used car market, diesel versions (dCi) are ubiquitous and, for the most part, highly recommendable, contrasting sharply with certain petrol engines (notably the 1.2 TCe) which have experienced serious failures.

✅ Strengths

Overall reliability of diesel engines (dCi), particularly the 1.6 and 2.0 dCi.
Superb road handling, precise chassis, and well-controlled body roll.
Spaciousness and modularity (individual removable seats, numerous storage compartments).
Suspension comfort and sound insulation (especially on Phase 2 and 3).
Unbeatable price/performance ratio on the used car market.

⚠️ Weaknesses

Disastrous reliability of the 1.2 TCe (H5F) petrol engine.
EDC dual-clutch automatic gearbox sometimes temperamental (dry clutch wear, ECU).
Rear seats heavy and cumbersome to remove (no flat folding floor like some competitors).
Onboard electronics: R-Link multimedia system bugs on Phase 3.
Aging of some interior plastics and seat imitation leather (cracking).

🎯 Verdict

The Renault Scénic III is an excellent used car choice, provided you target the right engines. It redeemed the Scénic II's reputation by offering high-level reliability on its diesel engines. The top choice is the 1.6 dCi 130, which offers the best compromise of performance/consumption/reliability (timing chain). The 2.0 dCi is indestructible but thirstier, ideal for towing. The 1.5 dCi remains a very relevant economical choice, provided you avoid examples used exclusively in the city. In petrol, the 1.6 16v is robust but sluggish. Major warning: absolutely avoid the 1.2 TCe, a real financial time bomb. Finally, opt for a manual gearbox, as the EDC6 automatic gearbox can prove costly to maintain after 100,000 km.
