Ford Focus

Faulty injectors cause severe juddering and knocking on acceleration. Problem occurs from approx. 140,000–150,000 km. Multiple injectors become leaky or faulty simultaneously. Ford has replaced all 4 injectors in individual cases without a permanent fix.

Symptoms: Heavy juddering, knocking on acceleration, engine misfires, power loss

The 1.5 EcoBlue diesel can suffer from premature timing chain wear. Ford's recommended fix is to retrofit the weaker original chain with the reinforced 8mm version that is standard fit from 2023.

Symptoms: Rattling from engine area especially on cold start, engine warning light, rough engine note

Ford recalled approx. 8,400 vehicles (production October 2014 to April 2015) because the camshaft sprocket can fracture due to material fatigue and damage the engine.

The EGR cooler develops cracks from extreme thermal cycling. Coolant enters the intake tract and forms black foam in the expansion tank. In the worst case, hydraulic lock.

Symptoms: Black or oily foam in coolant expansion tank, coolant loss without external leak, white exhaust smoke, overheating tendency.

The DPF on the 1.5 EcoBlue is prone to clogging, especially in short-trip use. Ford has released software updates improving the regeneration strategy. Check whether the latest software update has been applied before purchase.

Symptoms: DPF warning light, power loss, engine warning light P2002

Recall for 9,858 vehicles (Oct–Dec 2018) due to bolts at the brake pedal-to-master cylinder connection being at risk of fracture. Complete brake failure is possible.

Cracking and squeaking from the electric steering on parking manoeuvres. Isolated cases of steering failure with a warning message on cold start. Usually resolved under warranty.

On the 155 hp MHEV variants with manual gearbox, the synchro rings for 1st and 2nd gear wear prematurely. Failures documented from as low as 22,000 km. Ford does not offer improved replacement parts.

Early 2018–2019 model years had significant electrical issues: failed parking sensors, a faulty SYNC 3 system, defective stop-start and Auto Hold functions. Software updates resolve many problems.

The underbody has inadequate corrosion protection: weld seams unsealed, cavities open. Rust forms early in splash zones. The exhaust system corrodes quickly.
