Reliability, common problems and owner reviews for the Ford Galaxy / S-Max 2.0 EcoBoost (petrol). Check this before you buy used.
The 2.0 EcoBoost turbo petrol makes the big Galaxy/S-Max genuinely quick, but it's the thirsty minority choice in these diesel-dominated MPVs. It's a chain-driven direct-injection turbo, so the cautions are intake-valve carbon over time, coolant/thermostat and turbo care, and the well-known Ford EcoBoost coolant-intrusion attention on some units (monitor coolant level and watch for the degas/coolant issues). A serviced car on clean oil is strong and refined; just expect MPV-unfriendly economy. Most buyers should take the diesel.
