2020 BMW M5 a metal-shavings engine failure at highway speed is a safety event. I had total catastrophic engine failure at less than 50,000 miles. No warning lights, found metal shavings in the engine system and engine needs complete replacement. I discovered that the very first and most important service at 1200 miles was never performed by BMW of [XXX]. It has been detailed by managers in writing. They still sold me the car XXX without disclosing the risks to purchase the car without this service being done. The repair is estimated to exceed $97,000 in repairs. I believe there was neglect, wrongdoing, and fraud done by BMW of [XXX] and BMW of [XXX] since they admitted to this neglect of service and never warmed me of the know risks to purchasing a car like this. I have proof in writing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Coolant expansion tank is leaking on fuel injectors, coils and plugs on engine below causing ‘drivetrain malfunction’ which puts vehicle into Limp Mode. Car can begin to shudder, misfire and stall. BMW has an SIB on the expansion tank, but has done nothing to address the components underneath that get damaged. Feel free to Google BMW M5 coolant expansion tank issues.
