NHTSA complaint #11758988

Owner complaint summary

Description of the Complaint: I own a 2022 BMW X5 (VIN: [XXX], current mileage: approximately 39,500 miles as of 08/24/2026) equipped with the B58TU engine, which uses a plastic oil pump (part number 11418646454) rather than a metal one. I have not yet experienced an actual failure, but I am reporting this as a precautionary safety concern based on the following: 1. On BMW's official parts reference site (RealOEM.com), the oil pump for my specific vehicle is flagged with an "Attention! Observe PuMA measure 65494813" notice, indicating BMW's own internal system has identified a known issue requiring special observation for this part. 2. I have learned that BMW Korea has acknowledged this plastic oil pump issue following a government investigation, and has committed to a full free repair program for affected vehicles in Korea. 3. I am aware of multiple reports and complaints from other B58TU engine owners in the United States regarding this same plastic oil pump issue. 4. Given that the oil pump is a critical component for engine lubrication, a failure of this part while driving — particularly during highway or long-distance travel — could pose a serious safety risk, including sudden loss of engine oil pressure and potential engine seizure at speed. I am filing this report to bring this issue to NHTSA's attention before an actual failure occurs, and to request that this be considered as part of any pattern analysis regarding B58TU engine oil pump defects in the United States. - **Year:** 2022 - **Make:** BMW - **Model:** X5 - **VIN:** [XXX] - **Mileage:** 39,500 - **Component:** Engine and Engine Cooling (or "Engine Oil System" if listed separately) - **Attachments:** RealOEM.com INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
