I am reporting a potential safety concern with my engine. The oil pumps are known to fail due to plastic internal components. BMW has issued a new pump with metal parts, but existing engines are not being helped and if oil pressure drops the car can suddenly stop in traffic, creating a safety hazard.

Component: Engine Oil Pump (Plastic Internal Variant) Safety Risk: Sudden Loss of Motive Power / Engine Seizure Defect Description: The oil pump in the BMW B58 engine utilizes a plastic tensioning/adjusting ring that is prone to brittle fracture. At only 38,000 miles, my vehicle suffered a catastrophic internal pump failure, resulting in an immediate "Low Oil Pressure" warning and forced engine shutdown. Safety Hazard: Stalling at Speed: This defect causes an immediate loss of propulsion. If this occurs during highway merging or high-speed maneuvers, the driver faces an abrupt loss of power steering and braking assist, significantly increasing the risk of a high-speed rear-end collision. Imminent Seizure: Total oil pressure loss can lead to crankshaft seizure, potentially locking the drive wheels and causing a loss of vehicle control. Technical Evidence: BMW has released an updated part (P/N 11419895359) that replaces the plastic internals with a metal housing, acknowledging the original design is insufficient for the thermal loads of the engine. Post-repair inspection of my vehicle showed significant carbonized "soot" in the filter, indicating that the pump's underperformance caused localized overheating of the lubricant prior to the final failure. Request: NHTSA should open an investigation into the B58 oil pump (2019–2021 models) to determine the failure rate of the plastic-ring units. A safety recall is necessary to replace these units with the updated all-metal version before a high-speed seizure results in a fatality.
