Common Faults
Each fault below is drawn from real owner reports and UK garage patterns for this generation — not generic used-car advice.
1.2 PureTech wet belt degradation
criticalThe 1.2 PureTech three-cylinder uses a rubber timing belt running in oil. The belt sheds material into the oil pickup, starving the engine. Stellantis extended warranties but failures continue.
Check for: Ask for the belt replacement invoice (should be done by 6 years/60k miles, updated guidance). Look for low oil pressure warnings in the history.
Typical cost: £600–£900 belt job; £4,000+ if the engine goes
1.6 BlueHDi injector and AdBlue faults (diesel)
seriousInjector failures and AdBlue/SCR system faults are common on high-mileage diesels, often showing as warning lights and limp mode.
Check for: Any engine management light on start-up. Ask about injector or AdBlue repairs in the paperwork.
Typical cost: £400–£1,500 depending on the fault
i-Cockpit touchscreen glitches
minorThe central touchscreen controls almost everything and can lag, freeze or reboot.
Check for: Operate the heater and media through the screen on the test drive — if it's unresponsive now, it won't get better.
Typical cost: Software update usually free; screen replacement £400+
Rear suspension bushes wear
moderateRear axle bushes wear early on higher-mileage cars, causing knocks over bumps.
Check for: Listen for clonks on a bumpy road; check MOT history for bush advisories.
Typical cost: £250–£450
