Focusbuyer's guide

The Mk3 Focus is a high-volume used car on both sides of the Atlantic, and high volume means high numbers of badly maintained examples. Automatic and CVT shudder at low speed, oil consumption that only shows up after a long drive, and coolant leaks that creep toward overheating are the problems most buyers miss at a casual viewing. This guide gives you the checks to run before you commit.

This guide covers ten documented issues: automatic/CVT shudder or delayed engagement, engine oil consumption or leak, coolant leak or overheating, AC compressor or condenser failure, infotainment/camera electrical faults, suspension knocks and tyre wear, brake pulsation or seized caliper, water leak or accident repair, ADAS/radar calibration fault, and the full recall and campaign status checklist. Each fault has a field check and a real repair-cost range.

A well-documented Mk3 Focus with a clean scan and no active faults is a practical, affordable used car. A poorly maintained one will start showing those costs within months of purchase. Use this guide to know the difference at the viewing.
