Ford Focus Common Faults in Ireland
Mk4, 2018–2025 — compact family hatch. Updated 2026-08-19.
The Mk4 Ford Focus (2018–2025) drives brilliantly but the 1.0 EcoBoost wet-belt is a critical concern — pre-2018 examples were prone to belt failure causing engine destruction; later belts are improved but inspection at 100,000 km is essential. The 1.5 EcoBlue diesel suffers oil dilution. Best-buy: 1.0 EcoBoost 2021+ with belt evidence. Worst: pre-2018 wet-belt.

Which Ford Focus years should you avoid?
Avoid 2018, early 2019 Ford Focus models if you can. Early Mk4 1.0 EcoBoost wet-belt failures were catastrophic when they occurred — a €4,000–€7,000 engine rebuild (independent specialist; main dealers quote higher) on a €15k car.
Best and worst years to buy
Wet-belt revisions, mature 8-speed auto on petrol, and SYNC 4 infotainment delivered. 2021+ examples with documented belt change history are excellent value.

Before you buy or sell a Ford Focus
Two quick checks pay for themselves on any used Focus. First, check the car's NCT history before you buy — a missed or repeat-fail NCT often signals a chronic fault the seller is hoping you'll miss. Second, if you're weighing the Focus against rival models, you can compare the Focus against its rivals side-by-side on price, running costs and spec.
