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 1.3, 1.5 and 1.6 gasolina (serie M) reliable?

Suzuki's M series (the 1.3-litre M13A, 1.5-litre M15A and 1.6-litre M16A, with a timing chain and indirect injection) has a reputation as a simple, reliable engine: we have found no documented serious fault in the block or the chain. What is on record are minor faults or one-off campaigns: the catalytic converter and lambda sensors of the 2005-2010 Swift, the catalytic converter of the 2006-2007 SX4, the Swift's fuel hose and the Grand Vitara and Jimny tensioner pulley.[5][6][7][8][9][10]
