Ford S-Max
2.0 EcoBoost 176 kW/240 hp automatic, S-Max II (2015-2019) / Galaxy III
EcoBoost Van
240 hp EcoBoost in the S-Max: brisk for a van, but no driving fun.
Engine Weaknesses 6
The 2.0L EcoBoost R9CD (S-Max MK2, early Galaxy MK3) belongs to the engine generation with known engine block hairline cracks. Check coolant level and condition carefully before buying.
Symptoms: Coolant loss, white exhaust smoke, foamy coolant reservoir
The PowerShift gearbox in the S-Max/Galaxy with R9CD shows the known shudder and slip issues. Gearbox oil change every 60,000 km is essential; neglected servicing causes clutch damage.
Symptoms: Shudder on pull-away, slipping clutches in low gears, gearbox fault
The 2.0 EcoBoost uses a timing chain whose tensioner can wear from around 120,000 km. Rattling on cold start is an early sign; if ignored, engine damage follows.
Symptoms: Metallic rattle on cold start, rough running, warning light
Production-line design flaw up to mid-2019: a hairline crack in the cylinder block between the cylinders lets coolant enter the combustion chamber. Ford revised the block from mid-2019.
Symptoms: Coolant loss without external leak; rough cold start; white smoke from exhaust; coolant milky.
The turbocharger of the 2.0 EcoBoost R9CD wears with suboptimal maintenance. In the heavier S-Max/Galaxy with frequent overtaking and full-load motorway use, the turbo is under more stress.
Symptoms: Whistling noise from the turbo, dropping boost pressure, bluish exhaust smoke
The 2.0 EcoBoost uses only direct injection, so crankcase oil mist cokes the intake valves. Cleaning every 60,000–80,000 km recommended.
Symptoms: Power loss at mid-range RPM; increased fuel consumption; hesitation at 2,000–3,000 rpm; rough idle.
Vehicle Weaknesses 8
The 1.5- and 2.0-litre EcoBoost engines in the S-Max II are susceptible to hairline cracks in the engine block, causing coolant loss and in the worst case engine damage. Particularly affected are model years before mid-2019.
The 6-speed Powershift dual-clutch gearbox in the S-Max II is prone to clutch wear, juddering when pulling away, sticking in gears and limp mode activation. Repair costs are considerable.
Ford recalled over 200,000 Galaxy and S-Max vehicles in Europe because the original bolts securing the rear trailing arms can fracture from severe corrosion. If they break the rear axle can fail — acute accident risk.
Corrosion occurs at the rear axle of the S-Max II on track rod ends and axle bolts. Ford recalled affected vehicles. On untreated examples, fracture and loss of driving safety are a risk.
The adaptive headlight control unit in the S-Max II occasionally fails, disabling automatic beam levelling. The failure is listed as a common finding in TÜV reports.
On the Ford S-Max II, rust forms at the tailgate — particularly on lower folded edges and hinge holes — with increasing age. Tow bars are also affected, as corrosion protection around the mounting point often deteriorates.
The Sync 3 infotainment system freezes during temperature fluctuations or after extended standstill and needs to be restarted. Bluetooth connections drop and voice control responds unreliably, particularly on newer vehicles after OTA updates.
TÜV statistics and driver reports confirm above-average brake disc wear on the S-Max II at both front and rear axles. Brake hoses also become brittle with age, which can lead to loss of braking effect.
