7 known faults with sources
Applies if: Only the four-cylinder 1.5 EcoBoost.
Block cracks on the 1.5 and 2.0 EcoBoost with coolant lossCooling
- Engine / equipment
- Four-cylinder 1.5 EcoBoost and 2.0 EcoBoost: Kuga, Mondeo, S-Max, Galaxy, Focus and C-Max
- Period mentioned
- Approx. 2014–2019
- Symptoms
- Coolant loss with no visible leak, rough running on cold start, white smoke and, in serious cases, engine failure.
- Possible cause described
- Hairline cracks in the block let coolant into the cylinders; it mainly affects older 1.5 units and, less often, the 2.0. Ford revised the block in mid-2019.
- Check for the garage
- Watch the coolant level; if it drops with no external leak, run a pressure and combustion-gas test and check the spark plugs. Ask Ford by VIN about warranty actions.

Applies if: Only the 1.6 EcoBoost built from 2/6/2010 to 22/12/2014.
Overheating and cracked cylinder head on the 1.6 EcoBoostCooling
- Engine / equipment
- 1.6 EcoBoost: Focus, C-Max, Kuga, Fiesta ST and Transit Connect
- Period mentioned
- 2010–2014
- Symptoms
- The temperature rises, coolant is lost and, in extreme cases, oil sprays under pressure from a crack in the head with a risk of fire in the engine bay.
- Possible cause described
- Lack of coolant circulation causes local overheating of the head. In 2018 Ford recalled cars built between 2010 and 2014: it checks engine and cooling parts and adds a coolant level sensor with a warning.
- Check for the garage
- Check with Ford by VIN that the recall was done; watch the coolant level and stop at the temperature warning.
- Cost cited in the source

Transmission, lights and campaigns on the C-Max IIKnown weak points
- Engine / equipment
- Ford C-Max II and Grand C-Max (petrol and diesel)
- Period mentioned
- 2010–2019
- Symptoms
- A clutch that needs replacing, a pedal that does not return or a jerky gearbox (in the worst case gearbox failure); lights that fail or go out of alignment and moisture in the headlamps; a trip computer with false warnings; batteries, alternators and injectors (2010–2013); a clogged particulate filter; axle bushes.
- Possible cause described
- Recalls: pressure plate on manual EcoBoosts (fire risk), 2.0 Duratorq overheating from calibration (sump leak), 1.6 EcoBoost coolant-level sensor, the 2.0 diesel fuel sensor, alloy wheels and side and knee airbags.
- Check for the garage
- Check every campaign by VIN; test clutch and gearbox; check lights and particulate filter.

Coolant use, white smoke and rough running on the 1.0 EcoBoost: crack in the head next to the integrated manifoldEngine
- Engine / equipment
- 1.0 EcoBoost three-cylinder: Fiesta, Focus, EcoSport, B-Max and C-Max
- Period mentioned
- 2014–2019
- Symptoms
- The coolant level drops with no visible leak, white smoke comes from the exhaust and the engine runs rough (a cylinder misfires).
- Possible cause described
- Ford technical message SSM 47587 (October 2018) for the 2014–2017 Fiesta, 2015–2018 Focus and 2018–2019 EcoSport with the 1.0 EcoBoost says to run the extended cooling-system pressure test first and, if there is no external loss, inspect the exhaust manifold area integrated in the cylinder head: if there is a crack around the exhaust ports, the parts are replaced.
- Check for the garage
- Do not keep driving if the coolant keeps dropping: the 1.0 EcoBoost is damaged if it overheats. The garage pressure-tests the cooling system, looks for external leaks and, if there are none, carefully inspects the exhaust manifold area of the head for cracks.

Lack of power with the engine warning light and P0299 / P0234 on the 1.6 EcoBoost: wastegate solenoidInjection / turbo
- Engine / equipment
- 1.6 EcoBoost direct injection: Focus, C-Max, Kuga, Fiesta ST, Mondeo and Transit Connect
- Period mentioned
- 2013–2016
- Symptoms
- The engine loses power and the engine warning light comes on. The computer stores codes P0234 (turbo overboost), P0245 or P0246 (wastegate solenoid circuit) or P0299 (turbo underboost).
- Possible cause described
- Ford bulletin 15-0162 (October 2015) for the 1.6 EcoBoost of the Escape, Fiesta ST and Fusion says to check the charge-air-cooler pipes and vacuum lines first; if they are fine, the cause is the solenoid valve that regulates the turbo wastegate, and it is replaced.
- Check for the garage
- Read the codes. Check that the charge-air-cooler pipes and vacuum lines are not split or loose; if they are fine, test the wastegate solenoid (under the engine) and make sure its hoses are fully fitted before replacing the turbo.

1.0 EcoBoost wet belt: blocked oil pumpEngine
- Engine / equipment
- 1.0 EcoBoost three-cylinder with oil-immersed belts
- Period mentioned
- Approx. 2014–2021
- Symptoms
- Low oil-pressure warning just before a loss of power; sometimes the engine seizes without warning. With no oil pressure the vacuum pump that assists braking can also stop working.
- Possible cause described
- The oil-immersed belt material can degrade and shed debris that blocks the oil-pump pickup screen; the tensioner arm can also break. The US agency (NHTSA) is investigating almost 136,000 cars; most failures happened before the belt-change interval.
- Check for the garage
- With the oil-pressure warning, stop and do not restart. At the garage, check the belt and tensioner and look for debris in the sump and pump screen; use the exact oil Ford specifies and do not stretch the change intervals.

1.0 EcoBoost coolant hose that may fail (2011–2013)Cooling
- Engine / equipment
- 1.0 EcoBoost, nylon pipe between engine and coolant tank
- Period mentioned
- 2011–2013
- Symptoms
- Coolant loss, overheating and, if you keep driving, serious cylinder-head or engine damage.
- Possible cause described
- The nylon coolant pipe could fail at high temperature on about 44,700 cars built between October 2011 and October 2013. Ford replaced it in a 2015 service action and in 2018 committed to paying for outstanding repairs.
- Check for the garage
- Check with Ford by VIN that the service action was done; watch the coolant level and stop at the temperature warning.
- Cost cited in the source
- The pipe replacement was free; later damage, case by case by Ford.A rough figure from the original database, not an up-to-date quote.
