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 2.7 and 4.0 gasolina (2TR-FE and 1GR-FE) reliable?

The sources consulted describe them as robust chain-driven engines with few documented faults: on the 4.0 V6 (1GR-FE), the water pump, head gasket on early units and the coils; on the 2.7 (2TR-FE), the front crankshaft seal in the early years. Almost all the data comes from technical websites, not official campaigns.[5][6][7][8]
