Is the 1.2 TCe reliable?

Only with reservations: 1.2 TCe and 1.2 DIG-T engines built between 2012 and mid-2016 can burn a lot of oil because of poor piston ring sealing, with a risk of damaging the valves, stretching the chain or destroying the engine. Renault and Nissan dealt with it through technical notes and case-by-case assistance, without a recall; later production incorporates the fix.^{[1][2][3][4][5]}

Is the BMW B58 reliable?

The B58 (3.0 turbo straight-six, since 2015) is considered robust and less troublesome than the N54/N55 it replaced, and the sources do not document widespread internal failures. The known faults are on the periphery: the plastic oil filter housing, crankcase ventilation, gaskets and coolant. On units built before 2021 there are also US reports of an oil pump with a plastic housing.^[6][7][8][9]
