I am reporting a safety concern involving BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019–2021. These vehicles utilize a variable-displacement engine oil pump containing an internal thermoplastic adjusting component responsible for regulating oil pressure. Field failures are increasingly being reported in which this internal component fractures, resulting in sudden loss or instability of engine oil pressure. The failure frequently occurs during cold-start operation in low ambient temperatures. When the component fails, oil pressure regulation becomes erratic or is lost entirely. In many cases, drivers receive little or no actionable …

Oil pump for the 2020 model is made with plastic internals. The passage that controls the flow of oil into your engine is made of plastic. The car didn’t even have 40,000 miles and the plastic broke causing the passage to be in a very close to shut position not allowing enough oil to enter the engine in higher rpm. The mechanic told me this is the biggest thing he is starting to see and he works for BMW Service center of Mamaroneck. He’s seen over 150+ B58TU (engine model) of the year 2020 with broken plastic in the oil pump. For the 2021 model year and up to 2026 they have updated the oil pump to metal internals and metal passageways solving the issue but are not helping us 2020 owners and …

I am reporting a premature oil pump failure on my 2020 BMW M340i xDrive with 42 thousand miles. The vehicle has been well maintained and has not experienced any oil pressure warning lights. However, the electronic engine oil level measurement repeatedly fails to complete once the engine is fully warmed up. I have also received stored BMW fault code 21B2C7 relating to engine oil pressure plausibility/excessive oil pressure. The fault currently shows as inactive, but it was not present previously. I have monitored engine oil pressure using diagnostic software. Pressure is generally around 38–42 psi at hot idle, approximately 44–48 psi during cruising, and can rise into the 60–78 psi range …

NHTSA complaint 11756783, quoted in part. Filed by an owner and not verified by NHTSA or by us.

Component Involved:Engine Mechanical / Variable-Displacement Engine Oil Pump (Part #11418635032 / Updated #11419895359) Description of Safety Hazard / Defect:The early-generation B58TU engine features a variable-displacement oil pump equipped with an internal thermoplastic (plastic) adjusting ring. Due to continuous thermal cycling and mechanical stress, this plastic ring is prone to cracking and shattering without warning.When this internal component disintegrates, it causes an immediate loss of oil pressure to critical engine components. This creates a severe safety hazard, as the vehicle can experience a sudden loss of motive power or complete engine seizure while travelling at highway …

NHTSA complaint 11754090, quoted in part. Filed by an owner and not verified by NHTSA or by us.

Safety Hazard: Oil Pump Failure Leading to Sudden Engine Stall (BMW B58TU engines) Description of Defect: The oil pump module in the 2020 BMW M340i (G20) and many other models between 2019-2020 contains internal plastic components that are prone to thermal degradation and premature failure. These plastic parts can crack or disintegrate, causing a sudden loss of oil pressure. BMW corrected this in later models with metal parts but failed to issue a recall or the older models containing plastic parts. Safety Risk: A failure of the oil pump leads to insufficient lubrication of critical engine components, which can result in a sudden and complete engine seizure while the vehicle is in motion. …

NHTSA complaint 11750244, quoted in part. Filed by an owner and not verified by NHTSA or by us.

I am submitting this complaint regarding a potential safety defect involving the engine lubrication system on my 2020 BMW M340i with the B58 engine. The vehicle was purchased used from a single owner with low mileage and comprehensive maintenance records, with no indication of prior engine or lubrication issues. While traveling at highway speed, the vehicle suddenly displayed a low oil pressure warning and simultaneously entered a protective shutdown strategy, resulting in a significant loss of engine power. This forced me to rapidly slow down and merge across multiple lanes of traffic to reach the shoulder, creating a dangerous situation with a substantial risk of a rear-end or …
