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

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.

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
- Free under the recall.A rough figure from the original database, not an up-to-date quote.

Applies if: Same engine as the models NHTSA is investigating (Fiesta, Focus, EcoSport); have the belt checked at the garage.
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.
- Cost cited in the source
- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

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.

Ford diesel particulate filter: regeneration and emissionsExhaust and emissions
- Engine / equipment
- Kuga 2.0 TDCi and 1.5 / 2.0 EcoBlue; 1.5 TDCi and EcoBlue in the Focus, C-Max, Transit Connect and Transit Courier
- Period mentioned
- 2014–2023
- Symptoms
- Filter regenerations at excessive temperature, a damaged filter and particle emissions above the limit: the car can fail the emissions part of the roadworthiness test.
- Possible cause described
- Because of how the filter regenerates, particle emissions can rise over the years. Ford recalled several diesels (code 24E06): it recalibrates the regeneration, inspects the filter and replaces it if damaged. The German guide calls the filter the Achilles heel of modern Ford diesels.
- Check for the garage
- Ask Ford by VIN whether recall 24E06 is outstanding; check the filter and the regeneration history before the roadworthiness test.
- Cost cited in the source
- Free under the recall; before that, many owners paid for the filter themselves.A rough figure from the original database, not an up-to-date quote.

1.6 TDCi turbo starved of oilInjection / turbo
- Engine / equipment
- 1.6 TDCi (DV6)
- Period mentioned
- Approx. 2004–2018
- Symptoms
- Hissing from the engine, diesel smell in the cabin, very dark oil between changes and, eventually, a failing turbo with smoke and loss of power.
- Possible cause described
- The injectors’ copper washers stop sealing; the gases form carbon that gets into the oil and blocks the mesh filter in the turbo oil-feed pipe, starving the turbo. The wrong oil and switching off with the turbo very hot make it worse.
- Check for the garage
- Check the injector washers and the turbo oil-feed filter. If the turbo is replaced, also clean the sump, intercooler and feed pipe, or the new turbo can fail again. Use low-SAPS oil.
- Cost cited in the source
- Approx. €1,200–2,500 for a turbo replacement with oil-circuit cleaningA rough figure from the original database, not an up-to-date quote.
