Ford Focus Mk3 (C346)

Production Years: 2011 - 20183 Documented Faults

The Mk3 Ford Focus (C346) is a high-tech, global family hatchback that brought significantly improved safety features and refinement over its predecessor. Positioned as the default UK family car, it offers sharp handling, excellent motorway manners, and a vast array of trim levels to suit any budget. However, buying one now means carefully navigating the notorious 1.0 EcoBoost wet-belt risk and the deeply problematic Powershift automatic gearbox. When purchased in the right specification (ideally a manual diesel or a well-maintained petrol), it remains a superb, practical, and cheap-to-run family vehicle.
