Credov's researched list of the 2 faults the Ford Fiesta EcoBoost is known for (2012–2014), 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: Follow the small coolant hoses from the header tank to the turbo with a torch, looking for cracks.
Why it matters: Losing coolant this fast can overheat and warp or crack the aluminium cylinder head and blow the head gasket, and the source reports many affected engines needed full replacement.
What to look for: Ask for the wet belt receipt with its date and km, and for regular oil change records.
Why it matters: A degraded wet belt sheds rubber that can block the engine's oil pickup or the belt can fail outright, and either way the usual result is a damaged or seized engine.
