6-speed manual: the clutch fractures

critical

The clutch can fracture, the break damages the transmission case, and gearbox oil can leak from it. The car may become immobile, and the leaking oil can ignite on the hot engine or exhaust.

Show the rest

Ford issued three campaigns. The first went out in March 2018 (18V169000) for the 1.6 EcoBoost with the 6-speed manual, the second in November 2018 (18V845000) for the 1.0 EcoBoost cars, and the third in June 2026 (26V376000) because part of the earlier repairs had been done incorrectly. A car that has had the repair is not necessarily in order.

In the European range the 1.0 EcoBoost with the 6-speed manual is the most common Focus.

What to check

  • Pull away from a standstill several times: the clutch must not shudder, slip or kick
  • Pull away on a hill using the clutch: slipping shows up here first
  • Look under the car around the transmission housing: fresh or dried oil traces can mean a break

Door latch: the latching component breaks and the door can open while driving

critical

A component inside the door latch breaks, so the latch no longer holds properly: the door is hard to close, or it only catches on the first detent. The driver and the passenger may believe the door is properly shut when it is not, and it can open while driving.

Show the rest

Ford issued five campaigns between 2015 and 2023, and two of them, 20V331000 and 23V775000, recalled cars where the earlier repair had not been carried out properly. The 2020 campaign names six models: the 2011-2014 Fiesta, the 2012-2015 Focus, the 2013-2015 C-Max, the 2014-2016 Transit Connect, the 2015 Mustang and the 2013-2014 Fusion. The factory repair fits a revised door latch.

What to check

  • Close all four doors with normal force: none should need slamming, and none should bounce back
  • Push each door half shut: it must hold on the first detent, with no play
  • Open and close each one from the outside and the inside, including the child locks at the rear

Steering gear: the servo motor bolts corrode and the power assist is lost

critical

The electric power steering motor is attached to the steering gear housing with bolts. Slush thrown up from salted roads reaches those bolts and corrodes them. If a bolt cracks or falls out, the motor can separate from the housing and the power assist is lost: the steering becomes heavy, especially at low speed and when parking.

Show the rest

Ford issued two campaigns, in 2015 and in 2019, both specifically for the US states where roads are salted in winter. The factory repair replaces the bolts and applies a wax sealer; if any bolt is broken or missing, the whole steering gear is replaced. The same load arises anywhere roads are salted in winter.

What to check

  • With the car stationary, turn the wheel fully both ways: the assist must not cut out or be heavier on one side
  • After starting, check the dash: the power steering warning light must not stay on
  • From underneath, look at where the motor meets the steering gear: no rust streaks on the bolts, and none missing

MMT6 manual: worn shift mechanism, hard shifting when cold

expensive

The gearbox itself is reliable, but the shift mechanism wears noticeably between 100,000 and 150,000 km. Shifting becomes stiff, and it is most obvious when cold: the lever does not want to find its place, or the gear only goes in with force.

Show the rest

At high mileage the synchros on the first two gears wear out, and then the shift grates. The gearbox comes with a dual-mass flywheel, which is not the most durable part either.

between 100,000 and 150,000 km

What to check

  • Set off from cold: both first and second must engage without snagging
  • Stop and select reverse: it must not grate or need force
  • While rolling, change down into second: this is where worn synchros are audible

IB6 manual: little oil, leaks, and the synchro noise that follows

expensive

The gearbox is light and compact and reliable, but the small oil quantity makes it sensitive to leaks: not much has to escape before the level becomes critical.

Show the rest

Most complaints about synchro noise actually come from this, from the low oil level rather than from the synchro itself. Beyond that the input shaft bearing can wear out and reverse can fail. Every version comes with a dual-mass flywheel, which is not the most durable part.

What to check

  • Look at the gearbox housing from underneath: fresh oil means a leak, and here that is the main cause
  • Ask when the oil level was last checked and whether it has ever been topped up
  • While rolling, change down into second and third: grating means worn synchros

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
