Common Problems with the
2015 Ford Galaxy Mk3

Launch year: the Mk3 Galaxy went on sale in mid-2015 on Ford's CD4 platform, with seven full-size seats, 1.5 and 2.0 EcoBoost petrols and 2.0 TDCi diesels from 120 to 180PS.

What changed for 2015

  • •New CD4 platform shared with the Mondeo Mk5 and S-Max Mk2
  • •1.5 EcoBoost 160PS and 2.0 EcoBoost 240PS petrols, though Ford expected only 2% of UK sales to be petrol
  • •2.0 TDCi 120/150/180PS with six-speed manual or Powershift, and AWD on the 180
  • •Zetec, Titanium and Titanium X trims, with a 2.0 bi-turbo 210PS range-topper

Common MOT watch-outs

  • !Rear coil springs and dampers tired from seven-up loads
  • !Rear climate pipes corroding under the floor and losing heat to the back
  • !DPF regeneration problems on school-run and short-trip cars

All Known Issues

Dual Mass Flywheel (DMF) Wear

SeriousGearbox & Transmission

Like the S-Max, the Galaxy heavy body accelerates DMF wear especially on cars used for family hauling or towing. Symptoms include rattling at idle that stops when the clutch is pressed, vibration through the pedals and judder on pull-away.

Est. Repair Cost: £800-£1,500
Warning Signs:

Metallic rattle at idle with clutch up, Vibration through pedals, Judder pulling away from standstill

What to Inspect:
  • Listen for DMF rattle on cold start
  • Check for clutch slip under load in higher gears

Electric Power Steering (EPAS) Rack Failure

SeriousSteering

The Galaxy Mk3 and S-Max share a known EPAS rack issue where the piston inside the rack can disintegrate losing internal pressure. This clogs the reservoir filter and can starve the pump of fluid. Replacing the pump without replacing the rack will cause the new pump to fail again.

Est. Repair Cost: £600-£1,300
Warning Signs:

Loss of assistance on one or both sides, Heavy or inconsistent steering, Whining from power steering pump

What to Inspect:
  • Test steering lock-to-lock at walking pace
  • Check power steering fluid colour (should be clear red/pink)
  • Listen for pump noise

AdBlue / NOX System Faults

ModerateExhaust & Emissions

The AdBlue injector or NOX sensors on the Euro 6 EcoBlue diesels frequently fail, putting the car into a countdown mode where it will refuse to start once the miles reach zero.

Est. Repair Cost: £300–£1,000
Warning Signs:

"Engine will not restart in X miles" message, Engine management light

What to Inspect:
  • Check for recent AdBlue or NOX sensor replacements in the history

DPF Clogging on Urban Models

ModerateExhaust & Emissions

The Galaxy is a heavy car often used for school runs and short trips. The DPF clogs faster in these conditions and regeneration fails if the car cannot reach motorway speeds for long enough.

Est. Repair Cost: £250-£1,500
Warning Signs:

DPF warning light, Limp mode under load, Frequent regeneration fan noise after shutdown

What to Inspect:
  • Check MOT history for DPF advisories
  • Scan for soot-load percentage
  • Ask about usual driving pattern

Coolant and Heating System Leaks

ModerateCooling System

The Galaxy long coolant pipes running to the rear climate control can leak or block. The front thermostat housing and expansion tank are also common leak points. Rear passengers may notice weak or no heat if the rear pipes are blocked.

Est. Repair Cost: £100-£600
Warning Signs:

Low coolant warning, Rear passengers get no heat, Sweet smell from engine bay, Pink staining around hoses

What to Inspect:
  • Check coolant level and look for staining
  • Test rear climate control heat output
  • Inspect expansion tank and thermostat area

Buying Tips for 2015 Ford Galaxy Mk3

  • Check every seat folds and slides, and test the rear climate controls from the front
  • Ask whether the car has been a taxi or airport run car; seat bolsters and door shuts show it
  • On a Powershift, insist on proof of the 37,500-mile fluid changes
