Faults a 2020 example has usually reached
Documented onset mileage is at or below the ~81k miles an average 2020 car has covered.
TransmissionMedium
8-speed automatic harsh or delayed shifting
- Typically appears
- 60,000+ miles
- What to inspect
- Test kickdown and low-speed shifts
SuspensionMedium
Rear bushes and front drop links knocking
- Typically appears
- 70,000+ miles
- What to inspect
- Listen over speed bumps
EngineHigh
Loud metallic rattling from the top end on cold start due to camshaft chain stretch on 1.5 EcoBlue diesels.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Open the bonnet and perform a completely cold start. Listen closely to the top of the engine near the cam cover for a harsh rattle before oil pressure fully builds.
LightingMedium
Flickering, dim, or completely failed LED Daytime Running Lights (DRLs) requiring full unit replacement.
- Typically appears
- 40,000-80,000 miles
- What to inspect
- Turn on the ignition and headlights. Stand at the front of the vehicle and visually verify that both LED DRL strips are emitting a solid, even light without flickering or dead spots.
BrakesMedium
Electronic Parking Brake (EPB) fails to engage or disengage due to rear wiring loom chafing.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- With the engine running, cycle the EPB switch on the centre console three times. Listen for both rear caliper motors engaging smoothly without hesitation, grinding, or dashboard warning chimes.
Faults that appear at any mileage
Age, electronics and build-related issues that are not mileage-driven.
ElectricalLow
SYNC 3 infotainment freezes and camera dropouts
- Typically appears
- Age-related
- What to inspect
- Cycle every screen function and the camera
BodyMedium
Water pooling in the boot caused by failing pressure relief vents or rear light cluster seals.
- Typically appears

Check this exact carFord Focus · frequently asked questions
Is the Mk4 Focus a safer buy than the Mk3?
Yes on gearboxes, but the wet belt replaces PowerShift as the main risk.
Which trim sells fastest?
ST-Line in petrol with a full service history.
What should I always check?
Belt paperwork. Without it, price the job in.
What is the difference between the 1.0 EcoBoost mHEV and the standard EcoBoost?
The mHEV mild-hybrid versions, introduced around 2020, replace the standard alternator with a belt-driven integrated starter generator and add a 48-volt battery to improve torque and economy. Crucially for dealers, these mHEV engines utilise a timing chain, completely bypassing the notorious wet belt failures found in earlier non-hybrid 1.0-litre variants.
How can I easily identify if a Mk4 diesel model is ULEZ compliant?
All Mk4 Focus diesel models, including the 1.5 and 2.0 EcoBlue engines, meet Euro 6d-TEMP or Euro 6d emissions standards. This means they are fully ULEZ and Clean Air Zone compliant across the UK. You can quickly verify this on the forecourt by locating the blue AdBlue filler neck next to the diesel cap.
Are there any specific exterior checks required for the Active trim level?
The Focus Active features a raised ride height and bespoke plastic body cladding. While mechanically identical to standard models, you must inspect the wheel arch and sill trims for loose clips, scuffs, or impact damage. Replacement factory cladding is expensive and frequently on backorder, which can severely impact your preparation costs and retail margin.
