Ford S-Max I (WS) (2006–2015) (2006 – 2015)

Reliability score : 7.2/10

The first-generation Ford S-Max (chassis code WS) was launched in 2006, positioning itself as a 7-seater family minivan, but with a touch of dynamism and a sportier design than its larger sibling, the Galaxy. It quickly appealed with its agile road handling, modular interior, and good value for money. Voted European Car of the Year in 2007, it received a significant facelift in 2010 (phase 2), bringing aesthetic changes (front fascia, LED lights) and the introduction of EcoBoost gasoline engines and more powerful versions of the TDCi diesels. Overall, the S-Max I is a reliable vehicle for its category, but like any minivan, it is subject to wear of certain components and specific problems depending on the engine, particularly the widely used diesels in Europe.

✅ Strengths

Dynamic and pleasant road handling for a minivan
Cabin modularity (individual retractable seats)
Successful and timeless exterior design
Good spaciousness and trunk volume
Overall comfort (suspension, soundproofing)
Good value for money in the used market

⚠️ Weaknesses

Uneven reliability of certain engines (1.6 EcoBoost, 1.8 TDCi)
Rapid wear of certain consumables (brakes, tires) due to weight
High maintenance cost for high-end or poorly maintained versions
Minor electronic problems (sensors, modules)
Quality of certain interior plastics (scratches, aging)
Powershift gearbox (on some post-2010 models) can be problematic if poorly maintained

🎯 Verdict

The first-generation Ford S-Max remains an excellent choice for families looking for a spacious, modular, and pleasant-to-drive minivan. Its design has aged well, and its road handling is one of its major assets. For a confident purchase, prioritize the following engines: * Diesel: The 2.0 TDCi (140 or 163 hp) is the most balanced and reliable choice. It offers a good compromise between performance/consumption and proven robustness, provided rigorous maintenance (DPF, EGR, flywheel). It is the core of the range and the most recommended for high-mileage drivers. * Gasoline: The atmospheric 2.0 and 2.3 Duratec are safe bets in terms of pure reliability, but their consumption is high and their performance is just adequate. The 2.5 Duratec (Volvo T5) is a pleasure engine, but very thirsty and requires specific maintenance. To avoid or buy with extreme caution: * The 1.6 EcoBoost is to be avoided due to its recurring and costly overheating and engine failure problems. If you find one, ensure that all major recalls and fixes have been performed and documented. * The 1.8 TDCi should be strongly negotiated due to the fragility of its flywheel and injectors. Budget for these repairs if they
