Ford S-Max I (WS) (2006–2015) (2006 – 2015)
Reliability score : 6.8/10
The first-generation Ford S-Max (chassis code WS), produced from 2006 to 2015, made an impression as a family MPV with unexpected dynamism. Positioned between the C-Max and the Galaxy, it offered a sportier and more stylish alternative to traditional MPVs, with a 5 or 7-seat configuration. Voted "Car of the Year" in 2007, it appealed with its precise road handling, comfort, and modularity. A facelift in 2010 brought aesthetic (front fascia, LED lights) and technical evolutions, notably the introduction of EcoBoost petrol engines and more powerful TDCi diesels. Overall, the S-Max I is a reliable vehicle, but certain powertrains, especially the more recent and complex ones, require particular attention.
✅ Strengths
- Dynamic and precise road handling for an MPV.
- Suspension comfort and sound insulation (especially after facelift).
- Interior modularity and generous space (5 or 7 seats).
- Modern and sporty exterior design.
- Very reliable naturally aspirated petrol engines (2.0/2.3 Duratec).
- Globally robust 2.0/2.2 TDCi (PSA) diesel engines.
⚠️ Weaknesses
- Reliability of the 2.5 Duratec I5 Turbo and 2.0 EcoBoost SCTi engines can be costly if maintenance is not impeccable.
- High fuel consumption for powerful petrol engines (2.5T, 2.0 EcoBoost) under dynamic driving.
- Premature wear of the dual-mass flywheel on diesels (especially 1.8 TDCi).
- DPF clogging issues on diesels in urban use.
- Some minor electronic issues (sensors, wiring harnesses).
- Quality of some interior plastics before the facelift.
🎯 Verdict
The first-generation Ford S-Max remains an excellent choice for families looking for a spacious, practical, and enjoyable-to-drive MPV. Its reliability is generally good, but it heavily depends on the chosen engine and maintenance history. * For peace of mind and a controlled budget, prioritize the 2.0 Duratec-HE (naturally aspirated petrol). These are the most reliable and least expensive to maintain.
* The 2.0 and 2.2 TDCi (diesel) are good compromises between performance and fuel consumption, but require particular attention to the DPF and dual-mass flywheel, especially if usage is predominantly urban.
* The 2.5 Duratec I5 Turbo and 2.0 EcoBoost SCTi (turbo petrol) offer exhilarating performance, but their reliability is more unpredictable, and their maintenance is more demanding and costly. They are best reserved for informed buyers willing to invest in rigorous mechanical follow-up.
* The 1.8 TDCi should be avoided due to its recurring problems. A well-maintained S-Max, especially with the recommended engines, represents excellent value for money on the used car market.
