The 3 cylinder Ecoboost engine has been having big problems in the UK with coolant leaks resulting in complete engine failure.

Ford seem to be as sympathetic to those owners as they were to the mugs who got landed with the DSG gearbox.
Maybe they have fixed the problem now. Maybe. Are you feeling lucky?
I will stick with a nice big engine with no turbos or superchargers to go wrong. If you need more power get a bigger engine.
