4 important faults

critical2

Low pressure fuel pump: a recall, but without a fix

critical

The internal clearances of the low pressure fuel pump are small, so the friction is high and the pump is sensitive to vapour lock. The cause lies with the supplier: in June 2021 it changed the manufacturing process, and the new process did not hold the dimensions reliably.

Show the rest

The fault comes out when the fuel is low, or when the tank warms up in hot weather. Fuel pressure is then lost, the engine does not get enough fuel and can stop while driving. The authority calls this a loss of motive power, and it is the most serious consequence a fault can cause while under way.

The milder sign is hesitation at part throttle and sluggish acceleration, and the fault is reported above 40 000 kilometres.

In July 2025 the maker issued a recall for it under number 25S75 (25V455 at the authority), and it covers 850 318 cars from the 2021 to 2023 model years. One thing has to be known, though: when the campaign started the final repair was not yet ready, and owners first received only an interim notice. On an affected car it is therefore not enough to ask whether the recall has been carried out; it also has to be clarified whether there was anything to carry out.

above 40,000 km

What to check

  • Ask the franchised dealer with the chassis number: is it affected by the 25S75 campaign
  • If it is affected, ask what was carried out on it, and ask for proof of it
  • Watch for hesitation at part throttle and sluggish acceleration on the test drive

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

Ten-speed automatic: it jerks and clunks, and the maker says this is normal

expensive

The shifting of the ten-speed automatic is harsh: the transmission jerks, bangs, clunks and hesitates between gears. Slipping comes with it, along with late shifts, harsh downshifts, and the transmission sometimes not engaging a gear at all. Among the complaints there is also a sudden loss of power occurring on the motorway.

Show the rest

This is not individual bad luck: in April 2023 a class action was filed over it in the United States, and it covers the Expedition, Mustang, Ranger, F-150 and Navigator built from 2017 onwards which were fitted with this transmission. The fault is reported above 60 000 kilometres.

The most important thing to know is the maker's response. The maker did not issue a recall and did not replace transmissions, but issued technical bulletins instead, and according to the claim it told owners that the abrupt, harsh shifting is normal. No settlement has been reached.

For a buyer this means that the workshop's opinion decides nothing here. On the test drive it is your own experience that counts, and it has to be compared with what a properly working transmission of the same kind can do.

above 60,000 km

What to check

  • On the test drive have it shift all the way through: it should not jerk, bang or hesitate between gears
  • Watch the downshifts when slowing: a harsh downshift belongs here
  • Pull away from a standstill several times: the transmission should engage a gear without delay

Open deck block: the bore moves and the gasket cuts into itself

expensive

The block of the engine is of open deck design: the cylinder walls are not braced at the top. Under boost and heat the unbraced cylinder wall moves sideways, and this micro-movement puts a shearing load on the fire ring of the head gasket. The ring cuts further into itself with each thermal cycle, and because there is no solid backing underneath it between the cylinders, it extrudes into the coolant slots. In the end it lets pressurised gas and coolant through.

Show the rest

It is not the mileage that decides but the year of casting and the use. On the blocks cast between 2015 and 2019 there are grooves forming slots between the cylinders, and the risk is highest on those. In 2020 the maker revised the casting: in place of the open slots came small coolant passages drilled diagonally from the outer wall, and with that the metal backing returned. The number of failures dropped noticeably as a result.

The load is what counts, not the distance: the critical case is a heat-soaked restart after hard use.

The symptom is coolant going down with no visible dripping, white smoke, an uneven, stumbling idle, misfires (codes P0300 and P0316), mayonnaise-like oil and running hot.

The repair starts with a pressure test, then a revised gasket, a new cylinder head or a complete block replacement follows, depending on the extent of the damage. An engine that had already overheated before the repair can remain distorted, and then the coolant loss comes back.

What to check

  • Check the casting year of the block: a casting from between 2015 and 2019 is the risky one, post-2020 is the good one
  • If it is from between 2015 and 2019, ask for the repair history of the head gasket or proof of a block replacement
  • Look at the coolant level and ask whether it has had to be topped up
