NHTSA complaint #11731189

Owner complaint summary

I recently took my 2019 X5 to the BMW dealership because of the recall (Engine starter) and the code P0456 (NVLD Minor Leak Fault). At the same time, there's a warning that says, "Oil at a minimum level. Add 1 liter immediately". I have the 3 Year Oil Plan and asked them to put some oil, but the dealership said that they can't add oil because the oil level wouldn’t read properly. They told me they couldn’t diagnose it without charging me an extra 300 for further testing. Then, I read a lot of threads online and it seems that BMW quietly changed the pump to an all-metal design around 2020 but never issued a recall or extended warranty for the earlier cars. There's a lot of customers complaining with the B58TU engine found in many 2019–2021 BMWs (X5 xDrive40i, 540i, 340i, etc.). The variable oil pump uses a plastic internal adjusting ring that cracks over time. When it fails, oil pressure becomes unstable or is lost, often with little warning. A common early symptom is the oil level sensor test failing and stopping around 12-20%. In the worst cases, it can lead to sudden engine damage or the car shutting down while driving. I called up my mechanic, and he said that this is a common problem and it could be an oil pump issue that needs to be replaced. I asked him for a quote and he said approximately 5k or more. I believe this is a safety defect that deserves investigation Hoping for your kind consideration. I plan to keep my car as long as possible Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
