5 known faults with sources

Engines: 1.25 / 1.4 / 1.6 Duratec Ti-VCT (Petrol) · 1.0 EcoBoost (Petrol) · 1.6 EcoBoost ST (Petrol)

Applies if: Only with the PowerShift dry dual-clutch automatic (DPS6). Confirm the gearbox type.

Judder on the PowerShift dry dual-clutch gearbox (DPS6)Automatic gearbox

Engine / equipment: 6-speed PowerShift automatic with dry dual clutch (DPS6 / 6DCT250)
Period mentioned: Approx. 2011–2018
Symptoms: Shudder or judder when pulling away, especially in traffic; gearbox-module faults that can stop the car starting.
Possible cause described: Early wear of the dry clutches (the software did not compensate well for temperature), and failures of the control module (TCM) and clutch actuators.
Check for the garage: Read codes (e.g. P0900, clutch actuator), update the gearbox software and run the relearn drive cycle; if the shudder remains, replace the clutch. Ask Ford about campaigns or warranty extensions for the VIN.
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.

Engines: 1.0 EcoBoost (Petrol)

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.

Engines: 1.0 EcoBoost (Petrol)

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.

Engines: 1.6 EcoBoost ST (Petrol)

Applies if: Only the 1.6 EcoBoost built from 19/9/2012 to 16/12/2014.

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

Engines: 1.4 / 1.5 / 1.6 TDCi (Diesel)

Applies if: Only the 1.6 TDCi.

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.
