Ford Focus III (DYB) (2011 – 2018)

Reliability score : 6.8/10

The third-generation Ford Focus (codename DYB) marks the era of the “One Ford” program, aiming to design a global model for all markets. Renowned for its excellent comfort/handling compromise, it introduced a plethora of driving assistance technologies for its segment. The late 2014 facelift (often called Mk3.5) brought the famous “Aston Martin” style grille, a welcome redesign of the center console (fewer buttons), and the introduction of the SYNC 2 multimedia system (then SYNC 3 in 2016). While its dynamic qualities are undeniable, its mechanical reliability is very heterogeneous, particularly for EcoBoost petrol engines and PowerShift automatic gearboxes.

✅ Strengths

Exceptional chassis: precise steering, sharp front end, excellent comfort/handling compromise
Significantly improved sound insulation compared to the previous generation
Rich technological equipment for its time (automatic braking, lane keeping assist, automatic parking)
Very reliable 2.0 TDCi and 1.6 Ti-VCT engines
SYNC 3 multimedia system (from 2016) responsive and compatible with Apple CarPlay / Android Auto

⚠️ Weaknesses

Disastrous reliability of the PowerShift dry-clutch automatic gearbox (DPS6)
1.0 EcoBoost engine: risky and costly-to-maintain wet belt design
Rear passenger space and boot volume (316 liters) below the category average (Golf, 308)
Dashboard ergonomics before the facelift (too many buttons, small screen)
Quality of some interior plastics and uneven assembly

🎯 Verdict

The Ford Focus III is a brilliant car on the road, but requires extreme caution when buying used. If you're looking for a petrol engine, the sensible choice is the modest 1.6 Ti-VCT with a manual gearbox, which is indestructible. The very common 1.0 EcoBoost offers excellent driving pleasure but its wet belt system is a sword of Damocles: only buy with a 100% clear Ford service history and budget for the belt replacement. Absolutely avoid PowerShift automatic gearboxes on petrol engines (DPS6). High-mileage drivers will find their happiness with the excellent 2.0 TDCi diesel engines.
