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 1.0, 1.2 and 1.4 Fire reliable?

The 1.2 8v Fire is one of Fiat's simplest and most widespread petrol engines, with more than two decades in production and no serious or systemic faults documented. The sources consulted describe it as robust: its most-cited issues are isolated sensor failures (lambda sensor, crankshaft sensor), the ignition coil and somewhat high oil consumption at higher mileages; there is no pattern of timing belt breakage.[6][7][8][9][10][11]
