Ford Focus

Recall campaign: engine can overheat without a coolant level warning, causing cylinder head cracks and fire risk from oil onto hot surfaces. Approximately 56,000 vehicles affected in Germany.

Symptoms: No warning despite low coolant; first symptom is often already severe engine damage or smoke.

Fragments from the clutch pressure plate can be ejected and strike engine components, causing smoke and fire in the engine bay. 1.0/1.5/1.6 EcoBoost models with manual gearbox are affected.

Symptoms: Smoke development, sudden power loss, in extreme cases engine bay fire.

Without a coolant level warning the engine can overheat and the cylinder head can crack. Repair costs usually exceed the car's value at Focus DYB age.

Symptoms: White smoke from exhaust, coolant loss, engine stops.

The oil feed line to the turbocharger tends to leak. Oil starvation causes bearing damage in the turbo. Typical failure pattern: shaft seal defective, oil enters the intercooler.

Symptoms: Blue smoke when accelerating; oil film in the intake or intercooler; increased oil consumption; power loss at higher revs.

Ford recalled approximately 56,000 vehicles with the 1.6 EcoBoost (2010–2014). The missing coolant level warning allowed the engine to run with insufficient coolant, causing cylinder head cracks. Retrofit: sensor plus software update.

Symptoms: No warning on coolant loss, engine overheats unnoticed, white smoke, power loss, in worst case irreparable engine damage

The 1.6 EcoBoost (Focus, Kuga) suffered piston ring breakage and cylinder bore scoring, sometimes before 110,000 km. The downsized design puts heavy stress on components; cause is often a combination of overheating and oil starvation.

Symptoms: Zero compression in one cylinder, severe juddering, no power build-up, engine beyond repair, replacement engine costs £5,700–£7,500

Vehicles with 6-speed manual gearbox and 1.0/1.5/1.6 EcoBoost (Aug 2012–Jun 2016) were recalled due to faulty clutch pressure plates. In some cases a complete clutch replacement was required.

The PTU of the GKN all-wheel drive system has no active cooling. Above 150°C the system switches to FWD. TSB 5461 for oil leaks 2016–2017. An aftermarket cooling kit is strongly recommended for track use.

The GKN torque-vectoring rear differential (RDU) of the Focus RS Mk3 requires fresh specialist oil every 48,000 km. Neglecting this causes the clutch plate packs to overheat and the gears to wear prematurely.

Springs and shock absorbers are frequently flagged at inspection. The sportily tuned suspension of the MK3 wears chassis components more rapidly than its predecessor.

The Getrag six-speed shows synchromesh wear in 2nd and 3rd gear at higher mileages. A gearbox oil change with specialist fluid can delay early failure. Repair 1,500–3,000 EUR.

Rear wheel arch openings rust at the bumper transition edge. The roof above the rear doors can deform through body torsion. Boot water ingress through leaking spoiler fixings is widespread.

Launch control and drift mode put enormous strain on the clutch. Replacement including labour over 1,000 EUR. Clutch test: 5th gear, 50 km/h, full throttle — if revs rise without vehicle accelerating, the clutch is worn.

The standard 350×25mm one-piece discs on the Focus RS Mk3 overheat with aggressive driving and warp. Particularly after track days or hard mountain passes. Noticeable as pedal vibration under braking.
