What owners report
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.
The contact owns a 2021 BMW X4. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System). While the vehicle was in park(P), there were abnormal sounds coming from the engine. The contact stated that when the vehicle was shifted into drive(D) and the brake pedal was depressed, there was an abnormal sound coming from the front of the vehicle. The vehicle was taken to a dealer on several occasions, but the failure was not duplicated. The vehicle was then taken to an independent mechanic and was currently being diagnosed. The manufacturer was notified of the failure. The failure mileage was approximately 70,000.
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
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,
transfer case AWD/xDrive system drivetrain components The dealer diagnosed a transfer case failure on the BMW X4 xDrive. Vehicle displayed drivetrain malfunction warning. Repair estimate exceeds $20,000. The vehicle has under 50,000 miles. The issue appears consistent with known xDrive transfer case complaints. The warning light came on on January 7, 2026, at approximately 6 pm.
