Crunching or stiff gear selection, particularly when shifting from first to second or second to third gear, caused by premature synchroniser ring wear.

Typically appears

40,000-70,000 miles

What to inspect

With the engine running and the handbrake applied, depress the clutch fully and shift rapidly between first, second, and third gears. Listen for audible crunches and feel for excessive mechanical resistance.

Clunking noise from the steering column over rough surfaces or a lack of self-centring after cornering, pointing to steering rack or column universal joint wear.

Typically appears

30,000-60,000 miles

What to inspect

With the engine idling, rock the steering wheel left and right off-centre to listen for distinct knocks. On a brief forecourt drive, check if the wheel naturally returns to centre after a tight turn.

Coolant leaks from the water pump or thermostat housing, particularly prevalent on 1.0 Boosterjet engines, which can lead to rapid overheating if ignored.

Typically appears

50,000-80,000 miles

What to inspect

Shine a torch down the auxiliary belt side of the engine block to look for pink or blue crusty coolant residue around the water pump pulley, and check the expansion tank level.

The touchscreen infotainment unit freezes, reboots randomly, or suffers from 'ghost touches' where it selects options without physical input.

Typically appears

4-7 years

What to inspect

Turn the ignition on, allow the system to boot completely, and rapidly tap through the radio, settings, and sat-nav menus. Watch for severe lag, freezing, or unprompted screen changes.
