The essentials.

2 documented, sourced faults across its 5 engines.
That is not much data: if no other faults show up here, it does not mean it has none.
They all depend on the equipment or the production date: ask what this car has.
7 official recalls on record: ask for the chassis number (VIN) and confirm they have been done.
According to the data we have, the engines with the fewest documented faults are: 1.1 Ti-VCT (Petrol), 1.5 EcoBoost ST (Petrol), 1.5 TDCi / EcoBlue (Diesel).

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
Ask an official Ford dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.
