Ford S-Max II (CD539) (2015–2024) (2015 – 2024)

Reliability score : 7.2/10

The second-generation Ford S-Max (internal code CD539), launched in 2015, successfully succeeded the first iteration, consolidating its position as a dynamic family MPV. Based on the CD4 platform, shared with the Mondeo and Galaxy, it stands out with a sharper design, improved spaciousness, and a more engaging driving experience than most of its competitors. Available in 5 or 7-seat configurations, it offers exemplary modularity and appreciable comfort on long journeys. A minor facelift occurred in late 2019/early 2020, bringing minor aesthetic changes, technological updates (notably the SYNC 3.4 infotainment system), and the introduction of new powertrains, including the highly anticipated hybrid version. Overall, the S-Max II is a well-designed vehicle, but its reliability can vary signi

✅ Strengths

Modularity and spaciousness (5 or 7 seats)
Dynamic and precise road handling for an MPV
Suspension comfort and sound insulation
Successful exterior design, less 'utilitarian' than some competitors
Efficient and reliable diesel and hybrid powertrains (post-2018)
Modern technological equipment (depending on trim level)

⚠️ Weaknesses

Reliability of the 1.5 EcoBoost engine (pre-2020) problematic
Fuel consumption of gasoline engines (excluding hybrid) can be high
AdBlue system on diesels can be a source of costly breakdowns
Quality of some interior plastics inferior to German standards
SYNC 2/3 infotainment system sometimes slow or buggy (improved with SYNC 3.4)
Third-row access a bit tight for adults

🎯 Verdict

The Ford S-Max II is an excellent choice for families looking for a spacious, modular, and enjoyable-to-drive MPV. However, the choice of engine is crucial for long-term reliability. We recommend avoiding 1.5 EcoBoost versions produced before 2020 due to recurring timing belt and cooling issues, unless an impeccable service history and proof of preventive replacement of at-risk parts are provided. 2.0 TDCi/EcoBlue diesel engines are generally reliable and an excellent choice for high-mileage drivers, provided the AdBlue system is monitored and rigorous maintenance is performed. The 2.0 EcoBoost 240 hp version is a powerful and more reliable option than the 1.5, but its fuel consumption should be considered. The 2.5 Duratec FHEV (hybrid) is the most recommendable engine for its smoothness, urban fuel efficiency, and potentially exemplary reliability, but it is newer and therefore more expensive on the used market. In summary: prioritize 2.0 TDCi/EcoBlue diesels or the 2.5 FHEV hybrid. If you opt for a 1.5 EcoBoost, be extremely vigilant about the history and budget for potential fixes. The S-Max II remains a very relevant vehicle for its segment.
