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 BMW N13 reliable?

The BMW N13 (2011-2016), BMW's first turbocharged four-cylinder in three decades, powered the 114i, 116i, 118i and 120i (F20/F21) and the 316i (F30). It derives from the Prince engine developed with PSA, the same origin as the 1.6 THP. In 2013 BMW issued a technical service bulletin over timing chain and tensioner wear; oil consumption and carbon build-up on the injectors are other weak points shared with that family.[5][6][7]
