Most affected: 2.0 TDCi Powershift, 2.0 EcoBoost Powershift

Estimated cost: £1,500–£3,000Affects: 2010–2014

Typical symptoms

  • •Harsh gear changes
  • •Loss of reverse
  • •"Transmission Limited Function" message on dash

What to inspect before you buy

  • ✓Demand invoice proof of regular gearbox oil changes
  • ✓Check for smooth pull-away on an incline

Steering Rack Failure

The power steering rack can leak fluid internally into the track rod end boots, eventually running the pump dry and ruining the rack.

Most affected: All models

Estimated cost: £500–£1,000Affects: 2006–2014

Typical symptoms

  • •Heavy steering
  • •Whining noise from the power steering pump
  • •Loss of fluid from the reservoir

What to inspect before you buy

  • ✓Look for swollen rubber boots on the ends of the steering rack

Dual Mass Flywheel (DMF) Wear

SeriousGearbox & Transmission

The S-Max heavy body puts extra strain on the DMF. Symptoms include rattling at idle especially cold, vibration through the pedals and difficulty engaging gears. Some owners report failure as early as 60,000 miles on cars used in stop-start traffic.

Most affected: All manual models

Estimated cost: £800-£1,500Affects: 2006–2014Often appears around: 60,000-110,000 miles

  • ✓Listen for rattle that stops when clutch is depressed
  • ✓Test for judder pulling away uphill
  • ✓Check for smooth gear changes when warm

DPF Clogging and Vaporiser Failure

ModerateExhaust & Emissions

Short urban journeys prevent DPF regeneration. The fuel vaporiser can fail and the differential pressure sensor is a common secondary failure. Without the vaporiser working the DPF cannot regenerate and will eventually clog completely.

Most affected: 2.0 TDCi, 2.2 TDCi

Estimated cost: £250-£1,500Affects: 2006–2014Often appears around: 50,000+ miles with short-trip use

Typical symptoms

  • •DPF warning light
  • •Reduced power or limp mode
  • •Engine malfunction message
  • •Frequent regeneration fan noise

What to inspect before you buy

  • ✓Scan for P244B or P2463 fault codes
  • ✓Check DPF soot load via diagnostics
  • ✓Ask about usual driving pattern

Power Folding Seat Mechanism Failure

ModerateBodywork & Rust

The 2nd and 3rd-row seats fold flat electrically via motors in the seat bases. These motors can fail, the mechanisms can jam and the wiring in the seat channels can fracture. A non-folding third row reduces the car key practical advantage.

Most affected: Titanium, All models with power-fold seats

Estimated cost: £200-£600Affects: 2006–2014

Typical symptoms

  • •Seats will not fold or unfold electrically
  • •Grinding noise from seat motor
  • •One side folds but the other does not

  • ✓Fold and unfold all seats during inspection
  • ✓Listen for motor noise and smooth operation
  • ✓Check seat-folding wiring harness for damage

Coolant Leaks (Thermostat and Hoses)

ModerateCooling System

The thermostat housing, expansion tank and coolant hoses are common leak points as the car ages. Gradual coolant loss can lead to overheating if not caught early. The 1.6 EcoBoost models are also subject to the cylinder-head cracking recall.

Most affected: All models

Estimated cost: £80-£900Affects: 2006–2014

Typical symptoms

  • •Low coolant warning
  • •Sweet smell from engine bay
  • •Pink staining around hoses or expansion tank

What to inspect before you buy

  • ✓Check for unexplained coolant top-ups
  • ✓Verify recall completion for 1.6 EcoBoost models
