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. The vehicle's engine just fails I discovered the oil pump failure when I found it unusual that I had to add oil twice over a 6-month period. I took it to the dealer, where they informed me of the issue. This is extremely dangerous, especially when an engine locks up at high speeds on a highway.

Went to sit in driver rear seat and put on my seat belt and found it frayed apart. Thought this was od and tried the rear passenger side only to find the exact same thing. 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!
BOTH rear seat belts have broken off in the same spot. Went to use the driver's side rear seat belt and found it had been broken (frayed off). Moved to the passenger side and found the exact same thing. This could have been a bad situation if in an accident had occurred where they had not completely frayed but would have failed. Took it to my local dealer and they had no answers as to how this could have happened but suggesting that it most likely happened inside the recoil mechanism. They offered no other remedy other than to have me pay for replacement since the car was out of manufactory warranty,

What component or system failed or malfunctioned, and is it available for inspection upon request? - Suspension How was your safety or the safety of others put at risk? - Its giving head ache and body pain, driver & passengers are jumping / shaking / feeling very uncomfortable Has the problem been reproduced or confirmed by a dealer or independent service center? - Dealer mentioned all good, it designed this way Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - yes by BMW Service center Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - No The car's performance and handling is good, but the biggest concern is with suspension. 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 suspension ? The car is wobbling / shaking and very rough even for very small bumps / uneven surfaces (the car is just falling into it). It gives a headache when driving on a speed breaker even at 5 MPH. I really feel like the car has no suspension. Mentioning and selling with comfort mode where it is not doing the intended job is definitely a defective and design flaw. I would not have purchased it if it does not has comfort mode. Its happening all the time and from 5 to 70 mile speed. Please help me on this.
