Is the 2.0 TSI / TFSI reliable?

It depends above all on the generation. The earliest units (2008-2012, without Valvelift) have more oil consumption complaints and somewhat more chain and tensioner wear; from 2012 the Valvelift design reduced oil consumption but kept carbon build-up on the intake valves as a weak point until, around 2016, supplementary indirect injection was added. The thermostat housing with the integrated water pump leaks coolant in several generations.^{[1][2][3][4][5]}

Is the 2.3 EcoBoost reliable?

The 2.3 EcoBoost is the turbocharged four-cylinder petrol engine that Ford has fitted since 2015 to the Focus RS (350 hp), the fourth-generation Focus ST (280 hp) and the Ranger. Its documented fault is the cylinder head gasket on Focus RS cars built up to July 2017, which Ford repaired free of charge. We have found no evidence that it affects the ST, which uses a variant derived from the Mustang.^[6][7][8][9]
