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

Reliability score : 7.2/10

The second-generation Ford S-Max (internal code CD539) was launched in 2015, succeeding a model that had established the concept of the 'sporty' MPV. It retains this philosophy with a dynamic design, exemplary road holding for its category, and a modular interior offering 5 or 7 seats. Based on the CD4 platform, shared with the Mondeo and Galaxy, it benefits from modernized onboard technology (SYNC 2 then SYNC 3 system). A slight facelift occurred in late 2019/early 2020, bringing minor aesthetic changes, new engines (notably the introduction of EcoBlue and hybrid), and technological improvements. The S-Max II is appreciated for its compromise between driving pleasure, family space, and comfort. Its production ceased in 2024, marking the end of an era for large Ford MPVs.

✅ Strengths

Dynamic and precise road handling for an MPV
Exemplary spaciousness and modularity (individual seats, flat floor)
Suspension comfort and sound insulation (especially on high-end versions)
Successful exterior design, less 'utility-like' than some competitors
Wide choice of engines, including a reliable hybrid version
Good provision of safety and comfort equipment

⚠️ Weaknesses

Reliability of the Powershift automatic gearbox (DCT) if poorly maintained
Potential problems with the 1.5 EcoBoost (coolant intrusion)
Sensitivity of DPF/EGR/AdBlue systems on diesels in urban use
Quality of some interior plastics (easy to scratch)
SYNC 2/3 multimedia system sometimes slow or temperamental
High fuel consumption on powerful petrol versions

🎯 Verdict

The Ford S-Max II is an excellent choice for families who don't want to sacrifice driving pleasure. Its road handling is a benchmark in the MPV category. However, reliability depends heavily on the engine and maintenance. * For urban/suburban use and maximum reliability, the 2.5 Duratec Hybrid version is the most sensible choice, although newer and therefore more expensive on the used market. * For high-mileage drivers, the 2.0 EcoBlue engines are preferable to the older 2.0 TDCi, provided the AdBlue system is closely monitored and regular Powershift gearbox oil changes are performed if present. * The 1.5 EcoBoost should be considered with caution, meticulously checking the history and the absence of coolant issues. Buying advice: Prioritize a model with a clear maintenance history, especially for diesel versions and those equipped with the Powershift gearbox. A thorough road test is essential to ensure the gearbox functions correctly and there are no suspicious noises. The S-Max II remains a safe bet for anyone looking for a dynamic and versatile MPV, provided the engine and history are carefully chosen.
