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.^[1][2][3][4]

Is the 1.0, 1.4 and 1.6 8v EA111 reliable?

Eight-valve petrol engines, simple, with a timing belt. For the European 1.0 and 1.4, sources only record isolated incidents, mainly ignition faults in damp weather on the 1.4. In Brazil, the 2008-2010 1.0 VHT of the Gol, Voyage and Fox suffered lubrication-related noise, an oil campaign with extended warranty and a software recall in 2009.^[5][6][7][8]
