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 TCe / SCe reliable?

The 1.0 TCe/SCe (H4D/H4Dt) is a simply designed three-cylinder with reasonable reliability. Its most-cited fault is a noise or vibration from the turbo wastegate; the ECO-G (LPG) version adds its own gas-management faults and a 2023 recall over a risk of leaks and fire from the tank. An isolated case of a failed high-pressure pump is also documented, and no oil consumption pattern.[5][6][7]
