Engine Overview
The Ford S-Max 2 is available with 6 engine variants — from 120 to 241 hp. 3 variants had engine changes — the model year is crucial.
2.0 EcoBlue 110 kW/150 hp, S-Max II facelift (2018-2023) / Galaxy III facelift
- !! Continental Injector Coating Defect (2019) from 50,000 km
Continental injectors with a faulty internal coating (vehicles built Feb–Sep 2019). The coating delaminates and blocks the injector. Ford service action: free injector replacement (Ford TSB-20-2335). Affected vehicles: Transit, Ranger, Focus, Mondeo, S-Max, Galaxy, Edge.
Symptoms: Hesitation, poor idle, power reduction, increased fuel consumption, limp mode - !! DPF Clogging from Injector Soot Ingestion from 80,000 km
Faulty injectors generate excessive soot that prematurely clogs the DPF. On the high-output variant (190 hp), soot also blocks the low-pressure filter of the dual EGR system. Repair requires simultaneous replacement of injectors AND DPF (TSB-20-2335). Replacing the DPF alone does not resolve the issue long-term.
Symptoms: Fault codes P2002, P02EC, P02FA, check engine light, power reduction - !! Oil Bath Belt Clogs Oil Pump Strainer from 100,000 km
The oil bath timing belt deteriorates and clogs the oil pump strainer with debris. The engine dies from oil starvation — bearings, crankshaft, camshaft, and turbocharger are destroyed.
Symptoms: No warning: oil pressure drops, engine runs roughly, then total failure. Belt itself may appear visually intact.

Symptoms: Coolant loss, white exhaust smoke, foamy coolant reservoir - !! PowerShift Dual-Clutch Wear from 80,000 km
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 - !! Timing Chain / Chain Tensioner from 130,000 km
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

- !! eCVT Planetary Gearbox Failure from 150,000 km
The eCVT hybrid gearbox (electric drive + planetary gear set) can fail at very high mileages or from leaking shaft seals. Servicing as a sealed unit is very expensive.
Symptoms: Judder or rattling when pulling away, gearbox fault message, loss of drive. - !! Head Gasket Failure from 80,000 km
The 2.3 EcoBoost 206 kW (Focus ST) is prone to head gasket failure from high thermal stress. Spirited driving significantly accelerates wear.
Symptoms: Coolant loss without external leak, white exhaust clouds on cold start, overheating warning. - !! DC-DC Converter Failure — 12V System Collapse from 100,000 km
The DC-DC converter that steps down HV battery voltage to 12V can fail and cause the 12V electrical system to collapse. Reported sporadically on the C-Max/Kuga Hybrid with Atkinson engine.
Symptoms: All warning lights illuminate simultaneously; vehicle immobilised; 12V battery no longer charged; system errors on SYNC display.
