Known Ford Focus faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
011.5 EcoBoost coolant loss and coolant intrusion into cylinders (Mk3.5)
CriticalOccasionalCooling $4,000–$10,000 to fix
The 1.5 EcoBoost in facelifted Mk3 Focuses shares the EcoBoost family's coolant-intrusion weakness: coolant seeps past the head gasket into the cylinders, starting as slow unexplained loss and ending in misfires, bore corrosion and engine replacement. It is covered by the same US class action as the 1.6/2.0 versions. Slow coolant loss on one of these is never 'just a top-up' — walk away or price in an engine.
Symptoms to notice
Coolant disappearing with no visible leak
White exhaust smoke on cold start
Single-cylinder misfire codes
Sweet coolant smell from the exhaust
What to check
Check the expansion tank level cold and look for signs of frequent topping up. Cold-start the car and watch the exhaust for persistent white smoke. Commission a cooling-system pressure test or leak-down test before purchase.
Where to look: Head gasket/block deck inside the engine; evidence at coolant tank and tailpipe
Ask the seller
“Does it use coolant between services?”
“Has a pressure or leak-down test been done?”
“Has the head gasket or engine ever been replaced?”
02Power steering hose and pump leaks (Mk1 hydraulic PAS)
MinorCommonFluid Leaks $300–$900 to fix
Mk1 Focus hydraulic power steering systems leak from the high-pressure hose and pump seals with age. Left low on fluid the pump whines, then fails, and a groaning pump plus hose replacement adds up quickly on a low-value car. Fluid dripping onto the exhaust also creates a smoking/smell hazard that will spook any buyer behind you.
Symptoms to notice
Whining or groaning when turning, especially at full lock
Power steering fluid drips on the driveway
Heavy steering at parking speeds
Burning-oil smell after driving
What to check
Check the power steering reservoir level and look for wetness along the hoses down to the rack. Turn the wheel lock-to-lock with the engine idling and listen for whine. Look for fresh drips under the front of the car after the test drive.
Where to look: PAS reservoir and pump on the engine, hoses running down to the steering rack
Ask the seller
“Has the power steering ever needed topping up?”
“Have the PAS hoses or pump been replaced?”
