I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models.

Plastic components in the oil pump went out. BMW has made new oil pumps with metal components that are less fragile and do not fail as often. Outside of warranty these repairs can be very costly.
