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 Honda IMA híbrido reliable?

Honda's IMA hybrid system (Insight II, Jazz Hybrid, CR-Z and Civic Hybrid) has a good reputation for reliability in the British press, and its documented weak point is the ageing of the high-voltage battery, which turns on the IMA warning light. There were also two one-off campaigns: the DC/DC converter on the 2006 Civic Hybrid and the CR-Z software.[5][6][7]
