NHTSA Complaint #11690949 — 2019 BMW X5

The oil pump contains a plastic housing that fractured during regular use. (Yes, I did retain the part for inspection and can include photos of the defect here). Yes, the problem has been confirmed by my mechanic and the general public with multiple posts and videos shared widely across the internet and in vehicle forums. This failure caused the engine to lose oil pressure abruptly. Had this occurred at highway speeds or in heavy traffic, it could have resulted in a serious accident. BMW is aware of the problem and has redesigned the oil pumps for all X5s starting in 2020. There is no real warning for this potential failure which would cause the engine to cease. The problem is most commonly diagnosed by checking the oil level via the I-Drive System electronically, (there is no dipstick for these cars). The oil level cannot be provided on the screen due to significant pressure fluctuations caused by the damaged oil pump- and that's how you know you're at risk of engine failure. There has been no recall for the 2019 vehicles. All 2019 BMWs with the B58 engine, (and the Toyota Supra), include this dangerous and expensive design flaw and I believe a recall should be issued; the majority of these cars are still on the road. I estimate the total number of cars to be 250,000 cars. My oil pump had to be replaced or the car would be rendered undriveable. The estimate from BMW dealership #1 exceeded $11,000; the estimate from BMW dealership #2 exceeded $8,000. The car has less than 70,000 miles on it and this is a known issue for this model year.
