What to Look For

  • Full service history (crucial for timing chains/belts)
  • Smooth gear changes on automatic variants
  • Evidence of water ingress in the boot or footwells
  • Dashboard warning lights on cold startup

What to Avoid

  • Ex-rental or heavily abused examples
  • Cars with 'lifetime' gearbox oil that has never been changed
  • Specific early-year diesel engines without DPF/EGR history

Top Faults Across All Focus Variants

12V Battery Degradation and Failure

Minor
2011-201830,000–150,000 miles£80–£250

Lead-acid and AGM batteries have a finite lifespan. Modern cars are highly sensitive to voltage drops, causing bizarre electrical faults before the battery completely dies.

Shock Absorber Oil Leak and Failure

Moderate
2011-201870,000–120,000 miles£200–£400

Shock absorbers lose their damping efficiency over time, and eventually blow their seals, leaking hydraulic fluid.

Suspension Coil Spring Snapping

Severe
2011-201860,000–120,000 miles£150–£300

A very common MOT failure in the UK. Suspension coil springs corrode and snap, usually near the bottom pigtail.
