Why does our Ford Fiesta suffer from a flat battery?

My daughter in-law has a Ford Fiesta 1.0 litre EcoBoost on a two year PCP plan with a major Ford Dealer. Over the last 18 months the AA has recovered the vehicle on six occasions with a 'dead battery' following overnight parking. The dealership has investigated the car, (diagnostics each time), and after 2/3 days they report back that they cannot find a fault,.

With six months left on her PCP, what course of action would you advise? She had originally intended to buy the vehicle from Ford at the end of the second year but is now concerned about future reliability.

It seems to be the radio. Very common on Fords. if it has Bluetooth it does not switch off with the car and drains the battery constantly searching for the paired phone.
