Ford Focus Buyers Guide: Common Problems, Costs, and What to Avoid
The Ford Focus is one of the UK's best-selling cars of all time. There are hundreds of thousands on the used market at any given time, from £1,000 bangers to £15,000 nearly-new examples. But which one should you buy — and what will go wrong?
We analysed the Focus across two generations using real MOT failure data and component cost data to give you the definitive buying guide.
Ford Focus Mk2 (2004-2011)
Price range: £4.1k-£6.0k Insurance group: 14 MPG: 38 Reliability factor: 0.95
The Mk2 is the bargain Focus. Most are now 13-20 years old and well under £3,000. They're fundamentally solid cars but age-related issues are common.
Common faults:
- Dual mass flywheel — DMF failure causing judder and noise (£600-£1.0k, avg 85k miles)
- Clutch assembly — Clutch wear requiring replacement (£400-£650, avg 90k miles)
- Thermostat housing — Thermostat housing crack causing coolant leak (£80-£150, avg 70k miles)
- Coil springs — Coil spring fracture (corrosion-related) (£100-£200, avg 107k miles)
- Exhaust system — Exhaust system leak or corroded (£150-£400, avg 114k miles)
Verdict on the Mk2
The Mk2 is a good buy if you find one with a documented service history and no signs of the dual mass flywheel going. Budget £500-1,000 for likely repairs in the first year.

Ford Focus Mk3 (2011-2018)
Price range: £6.4k-£7.0k Insurance group: 12 MPG: 52 Reliability factor: 0.88
The Mk3 is better to drive and more refined, but has some known problem areas — particularly the 1.0 EcoBoost engine and the Powershift automatic gearbox.
Common faults:
- Timing belt — Timing belt replacement due (£350-£550, avg 75k miles)
- EcoBoost coolant hose — Coolant hose split causing overheating (£100-£200, avg 50k miles)
- EGR valve — EGR valve clogging causing limp mode (diesel) (£250-£450, avg 70k miles)
- Coil springs — Coil spring fracture (corrosion-related) (£100-£200, avg 82k miles)
- Ball joints — Ball joint wear causing play in suspension (£80-£180, avg 92k miles)
The EcoBoost Warning
The 1.0 EcoBoost engine is brilliant when it works — 125bhp from a 1-litre three-cylinder with great fuel economy. But early versions (2012-2014) have a known coolant leak issue that can destroy the engine. Check for:
- Coolant level drops
- White residue around the coolant bottle
- Any history of degas hose replacement
Later cars (2015+) had the issue largely resolved.
Avoid the Powershift
The dual-clutch Powershift automatic gearbox is the Focus Mk3's biggest weakness. Clutch shudder, judder, and rough shifts are extremely common. If you want an automatic Focus, look elsewhere — or budget for a £900-1,800 clutch pack replacement.
Verdict on the Mk3
The manual petrol Mk3 (1.0 EcoBoost 2015+ or 1.5 TDCi) is a great family car. Avoid the Powershift auto and early EcoBoost engines.

Which Focus Should You Buy?
| Mk2 | Mk3 | |
|---|---|---|
| Budget | Under £3,000 | £3,000-£8,000 |
| Best engine | 1.6 Ti-VCT petrol | 1.0 EcoBoost (2015+) |
| Avoid | High-mileage TDCi | Powershift auto |
| Reliability | 0.95 | 0.88 |
| Annual service | £280 | £300 |
On a tight budget? Mk2 1.6 petrol with under 80,000 miles. Simple, proven, cheap to fix.
Want something nicer? Mk3 1.0 EcoBoost manual (2015+). Great to drive, economical, and the coolant issues were mostly sorted.
