2021 BMW X4 M problems

“I am reporting a safety concern regarding BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found on models from 2019 to 2021. The oil pump in these vehicles is failing prematurely. I was told this by service technicians at BMW and confirmed it through my own research. The oil pump failure is due to a plastic adjusting ring breaking. The result is severe oil pressure loss and engine failure. This is uncommon for a vehicle that has 65k miles. The engine failure comes without warning; there are no check engine light warnings.

Took it to the dealer in Visalia, CA. They said that they have never seen anything like that before. After discovering that both belts were broken in the same spot, they concluded it must be caused by wear in the retracting mechanism, but because the car was out of manufacturer's warranty they could only sell me new ones. I believe this is a very serious safety issue because as they were starting to fray apart the belts may have not had enough strength to restrain someone during an accident. Glad this was discovered before that happened!”

Bad experience in the driver's seat and more bad in the passenger seat. I understand if the suspension is not performing in sport mode, but even in comfort mode the suspension is not even working 10%. Really frustrated and getting depressed. Why is it mentioned as comfort mode and not doing the intended job ? Why is the car being advertised and sold as it has Adaptive suspension ? really the car has…”
