Ford S-MAX Mk2 Common Problems & Reliability

The Mk2 Ford S-MAX is a more refined, mature, and quieter evolution of the original, sharing its sophisticated platform with the Mondeo Mk5. Positioned as a premium family MPV, it offers a vastly improved cabin, advanced safety tech, and a very comfortable ride, though it lost a fraction of the Mk1's sharp handling. In the UK, it remains an excellent choice for large families, but it introduces complex new electronics and the risky 1.5 EcoBoost engine to the lineup. It is best suited for buyers wanting a sleek, comfortable 7-seater who are willing to carefully navigate the engine and gearbox choices.

Inspection Checklist for Ford S-MAX Mk2 Buyers

✓Avoid early 1.5 EcoBoost petrol models (pre-2019) due to well-documented issues with coolant intrusion into the engine cylinders, requiring a new engine.
✓Check the Powershift automatic gearbox (if fitted to early diesels) for shuddering; later models switched to a more reliable conventional torque converter.
✓Verify the SYNC 2 or SYNC 3 infotainment system works without freezing; SYNC 3 (post-2016) is highly preferred for Apple CarPlay/Android Auto support.
✓Inspect the power-folding rear seats (if optioned) to ensure the electric motors haven't failed or jammed due to trapped debris.
✓Listen for clunks from the front suspension when pulling away, indicating worn MacPherson strut top mounts or lower control arms.
✓Check the DPF and AdBlue systems on diesel models, as these large cars are often subjected to short, DPF-clogging urban journeys.
