Ford Focus Mk4 buying guide
The fourth-generation Focus was built from 2018 to 2025 with EcoBoost petrol and diesel engines, plus the 2.3 turbo ST, and was facelifted in 2022. The main checks depend on which engine and gearbox the car has and when it was built.
The versions
- 1.0 EcoBoost three-cylinder turbo petrol (timing belt in oil on early cars, chain from mid-2019) and 1.5 EcoBoost
- Diesel engines; mild hybrid 1.0 EcoBoost versions also exist
- ST (2019 to 2025): 2.3 turbo petrol, 280hp, six-speed manual or seven-speed automatic, hatchback or estate
- ST 2.0 diesel, 190hp, before the 2022 facelift
What to check on a Mk4 Focus
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
1.0 EcoBoost wet belt and oil changes
What to look for: On a 1.0 EcoBoost, check the build date and look for a fully stamped service history with oil changes on time. With the engine off, pull the dipstick and note whether the oil level is above the full mark or smells of fuel.
Why it matters: Cars built before mid-2019 have a timing belt that runs in oil. It can break down early if the engine isn't properly maintained, and a rising oil level or fuel smell can point to belt debris or fuel dilution. Cars from mid-2019, and all mild hybrid 1.0 engines, use a chain instead.
Recall work
What to look for: Before you travel, enter the registration on the DVSA recall checker or ask a Ford dealer to check the VIN for outstanding recalls.
Why it matters: The Mk4 has had several recalls, mostly on early cars: rear child locks, brake pedal hinge bolts, front suspension bolts, rear doors on the estate that could open without warning, seat belt anchorages and chafing of the engine bay wiring loom on cars built from March 2018 to March 2020. A car with all the recall work done is the one to look for.
Automatic gearbox behaviour
What to look for: On an automatic, drive in stop-start traffic and at steady speeds, and note any jerky or hesitant changes. Ask whether software updates have been done.
Why it matters: Owners have reported jerky automatic gearboxes on this generation. A gearbox control software update is the usual first step; if the problem persists, a specialist inspection is the next.
