Credov's researched list of the 2 faults the Ford Fiesta ST WZ is known for (2010–2014), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Look for low coolant, crusty coolant residue or fresh oil near the turbo, and ask for the overheating recall record.
Why it matters: The hazard stated in the recall notice is a cracked cylinder head, an oil leak and an engine-compartment fire. An un-recalled or previously overheated example can need a cylinder head or a complete engine.
What to look for: Check every door latches on the first close, and doesn't move or show 'door ajar' when pushed from inside.
Why it matters: A door opening on the move is a fall-out hazard.
