2016 BMW 3 Series POWER TRAIN,ENGINE

My vehicle functioned normally without any faults for the approximately year and a half/ ~20,000 miles I used it. The one day I attempt to start my vehicle in colder weather (-6 degrees fahrenheit) and my starter fried and my engine seized up. I have heard of other occurrences like this happening where BMW owners attempted to start their vehicles in colder weather, have a fault come up as "starter/ignition malfunction" and then leading to an engine seizing. I believe this to be a faulty product from BMW.

THIS HAPPENED TWO SEPARATE TIMES ABOUT 2 WEEKS APART.. THE CAR WAS STOPPED AT A STOPLIGHT. FOOT ON BRAKE. SUDDENLY ENGINE STARTED REVVING AND CAR LEAPED FORWARD. BRAKE DID NOT STOP IT. THE SECOND TIME, (AUGUST 31, 2020) THE CAR REARED-ENDED THE CAR IN FRONT, POSSIBLY CAUSING INJURY TO THAT DRIVER. NEITHER CAR WAS HARMED.

TO NHTSA: NOT TOO LONG AGO THE TIMING CHAIN AND REAR DIFFERENTIAL PINION BEARING WENT OUT ON MY 2016 BMW 320I ([XXX]) TIMING CHAIN ISSUE SHOULDN'T OCCUR ON A MOTOR WHICH ONLY PRODUCES 180 HORSEPOWER WITH NO MODS OR TUNES. THE REAR DIFFERENTIAL SHOULD DEFINITELY NEVER GIVE OUT UNLESS YOU'RE PUSHING OVER 700 HORSEPOWER ON A STOCK DIFF. AGAIN MY CAR HAS 180 HORSEPOWER AND HAS NEVER BEEN MODDED. THIS IS JUST RIDICULOUS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
