Check a Ford Focus advert (free) →The Ford Focus has 35 known faults in our database across 3 generations, 27 of them rated high severity. The most serious are gearbox (the wet-clutch Powershift automatic transmission) and engine (timing belt tensioners on Zetec-E petrol engines are prone to failure). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.

A number of vehicles fitted with a 1.0 1.5 or 1.6 Ecoboost engine and 6-speed manual transmission could suffer clutch pressure plate fracture. This results in clutch smell reduced vehicle speed and performance. In the unlikely event of clutch pressure plate fracture a noise (thud / bang) could be heard from the vicinity of the transmission in extreme cases resulting in clutch / transmission fragments being released and striking under hood components creating a risk of smoke and fire from the under hood area.
Put right by: To prevent the repeated heating /cooling events a new calibration has been developed for vehicles fitted with Engine Stop Start feature. The software with the additional feature sets the Instrument panel Wrench light and de-rates the engine performance if prolonged clutch slip is detected. The software feature includes a drive cycle strategy for latching the wrench light and engine performance de-rate if the customer should experience repeated clutch slip events. For vehicles that do not have Engine Stop Start feature an alternative clutch kit has been released.

A small batch of alloy wheels may have a casting defect that may initiate a fatigue crack and result in wheel failure.
Put right by: Check wheels on affected vehicles for a specific batch code. Replace those wheels which have the identified batch code.
The engine control module calibration may not adequately detect an overheat condition in certain 2.0L Duratorq Diesel engines. In extreme cases an overheated engine can result in a breach of the oil sump leading to loss of the engine oil.
Put right by: Recall the vehicles that are likely to be affected and download revised software for the control module calibration that improves overheat detection and provides an instrument cluster warning indicator to the driver and engine de-rate strategy.
Localized overheating of the engine cylinder head may cause the cylinder head to crack.This may cause a pressurized oil leak which in extreme circumstances could result in a fire in the engine compartment.
Put right by: On affected vehicles Inspect engine and cooling system. Replace affected components and fit a Coolant Level Sensor along with associated software to provide and audible and visual warning to the driver.
The airbag initiator may be defective and may prevent the side airbag(s) and/or knee airbag deploying in the event of an accident. In a collision the airbags not deploying could put the occupants at further risk.
Put right by: Recall the 1943 vehicles that are likely to be affected to check and where necessary replace the side and knee protection airbags complete with initiators.
Engineering investigations have identified that vehicles operated in countries which have high road salt usage during winter months may experience an increased risk of corrosion build up. In extreme cases the corrosion can propagate into the electronic circuits and result in overheating. In rare cases the overheating may be sufficient to ignite the module and surrounding wiring and components.
Put right by: A supplemental wiring loom that removes the power supply to the fan control module when the ignition is switched off is required to be fitted to affected vehicles. An additional water shield must also be fitted to protect the module against water entry and corrosion build up.
Due to high road salt usage in winter the engine cooling fan module may suffer from corrosion and may overheat and ignite.
Put right by: Recall affected vehicles to modify wiring loom and to fit water shield to module.

An overdue cambelt is the most expensive thing a seller can fail to mention on a used Focus. These are the figures UK specialists work to.
The Mk3 Focus 1.0 EcoBoost (2012 to 2018) has a wet belt: Ford's own specification lists a belt-in-oil drive. Ford's original schedule for this belt was 10 years / 150,000 miles. In June 2026 Ford told the US safety regulator NHTSA it was cutting that to 6 years / 100,000 miles for vehicles worldwide with this engine, which it calls the 1.0 Fox Classic, because degraded belt material can block the oil pickup and starve the engine of oil. UK advice was still 10 years / 150,000 miles into 2025, so plenty of cars with a full service history are past the new figure. The revised figure is recorded, and specialists advise changing it sooner still. The Mk4 Focus, from 2018, has the chain version instead, so a 2018 car could be either.
The Mk4 Focus (2018 to 2025) has the chain version of the 1.0 EcoBoost from launch, including the 125 and 155PS mild hybrids. Ford's specification sheets list a timing chain with a hydraulic tensioner for this version of the 1.0 EcoBoost, so there is no cambelt to replace. Every 48V mild hybrid 1.0 EcoBoost has the chain engine. The earlier engine with the wet belt looks similar and carries the same badge, so on a car near the changeover check the engine code rather than the badge.
Ford's schedule splits on build date: 140,000 km (87,000 miles) or 10 years for cars built up to July 2011, and 180,000 km (112,500 miles) or 10 years after that. The shorter pre-2011 figure is recorded. This engine is known for tensioner problems, so it is critical to replace the water pump at the same time.
IMPORTANT: this four-cylinder 1.5 EcoBoost (2014-2018, Sigma-derived) runs a conventional DRY external cam belt and a crank-driven oil pump, so it has no belt-in-oil component at all. Do not confuse it with the 1.0 EcoBoost wet belt, or with the later Mk4 three-cylinder 1.5, which is chain driven. Ford officially recommends 150,000 miles or 10 years; specialists advise dropping this to 100,000 miles, which is recorded here.
The 1.6 Ti-VCT petrol (Sigma) uses a dry belt. Ford's schedule for this specific engine was reduced to 8 years / 100,000 miles, against 10 years / 100,000 for other Sigma variants, reportedly because the variable cam timing units load the belt harder. Some US-oriented sources quote 150,000 miles / 10 years; the shorter UK figure is recorded. Failures are rare but this is an interference engine.
The 2.0 TDCi (PSA DW10 Duratorq) is belt driven on a Ford schedule of 125,000 miles (200,000 km) or 10 years for belt, tensioner and idlers. The job is labour-heavy because the engine has to be lifted. NOTE: this row covers the Mk2 and Mk3 TDCi only. The Mk4 Focus 2.0 diesel is the EcoBlue, which runs a WET belt and is a different proposition entirely.
The Mk4 Focus (from 2018) and the S-Max and Galaxy (from the September 2018 update) offered the 2.0 EcoBlue diesel. The 2.0 EcoBlue runs its timing belt and a separate oil pump belt in oil (a wet belt), the same engine as the Transit vans. Ford's original schedule was 10 years / 150,000 miles. Ford's published cut to 6 years / 100,000 miles names only the vans, and no car-specific revision was found, but the engine and the cause (fuel dilution of the oil during DPF regeneration) are the same, so the van figure is recorded as the safer one. Change the oil pump belt with the timing belt. Not to be confused with the 1.5 EcoBlue, which is a conventional dry belt.
The 1.8 TDCi (Lynx) originally drove its high-pressure injection pump from the crank by a chain. On engines built from October 2007 that chain became a belt running in oil (a wet belt), designed by Dayco, while the camshaft stays on a conventional dry belt. Cars built before October 2007 have the chain, so a 2007 or 2008 car needs its build date checked. Ford's schedule is reported as 10 years / 125,000 miles for both belts, and Dayco says Ford specify the pump drive at 120,000 miles; the shorter figure is recorded. Change both belts together.
The three-cylinder 1.5 EcoBoost is in the Mk4 Focus (150 and 182PS) and the Mk8 Fiesta ST (200PS). Ford's specification sheets list a timing chain with a hydraulic tensioner, so there is no cambelt to replace. This is not the earlier four-cylinder 1.5 EcoBoost (to 2018), which has a conventional dry belt. Some sources report that engines built from February 2019 drive the oil pump by a belt running in oil, which Ford's sheets don't mention, so ask for the service history to show the oil pump belt if the car is near 10 years old.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
Three stand out. Gearbox: the wet-clutch Powershift automatic transmission (Getrag 6DCT450) requires fresh fluid (typically 50000 to 80000 miles). Engine: timing belt tensioners on Zetec-E petrol engines are prone to failure (typically 60000 to 90000 miles). Engine: rainwater or washer fluid can drain into the spark plug orifices (typically 60000 to 100000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
No Ford Focus year is a write-off, but the Mk3 (2011 to 2018) carries the most serious faults: engine, gearbox, cooling system, suspension and electrics. The Mk2 (2004 to 2011) and Mk1 (1998 to 2004) have high-severity faults on record too. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the gearbox and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for delay in engaging drive, sudden loss of engine power and engine misfires or runs roughly. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 35 known faults before you travel. Check a Ford Focus advert →
The DVSA lists 38 safety recalls for the Ford Focus issued between 2012 and 2026. The most recent, from June 2026, is "Transit Courier: Diesel DV-Neo Engine Coolant Pump Update". Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it. This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.
Owners report 44.9 mpg on average across the Ford Focus engines with data, about 80% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 9,033 owner submissions.
