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 2.0 / 2.4 i-VTEC reliable?

Naturally aspirated Honda petrol engines (K20/K24 and R20) with a timing chain. The only serious documented fault is camshaft wear in the early K20s (2003-2004); the R20A and K24Z show no serious faults in the sources consulted, and only isolated cases of oil consumption appear. The sample of testimonies is small.^{[5][6][7][8][9][10]}
