2004 BMW 545I Engine And Engine Cooling Problems

I CAME BACK FROM MY SUMMER HOLIDAY, AND RESTARTED MY CAR. A LOT OF WARNINGS APPEARS ON THE ODOMETER. ABOUT ENGINE, AIRBAGS, STEERING, TIRE PRESSURE, AND SEAT BELT. (I HAVE CHECKED THE TIRE PRESSURE, IT IS NORMAL. AND I ALWAYS LOCK THE SEAT BELT BEFORE DRIVING). IN ADDITION, THE NAVIGATION SCREEN AND RADIO DIED. FURTHERMORE, THE CAR LOSE ELECTRICITY AFTER IT SHUTS DOWN. AFTER MORE THAN 3 HOURS OF SHUT DOWN, IT WON'T HAVE ENOUGH POWER TO RE-IGNITE. I CHECK ON NHTSA WEBSITE THAT THERE ARE THREE RECALL ISSUES THAT MY CAR WAS INCLUDED, AND RELATED TO THE ISSUES I AM REPORTING RIGHT NOW. ABOUT AIR BAGS (08V384000), ENGINE (12E029000), AND ELECTRICAL SYSTEM (12V126000). BUT I CANNOT FIND OUT ANY INFORMATION BY MY VIN NUMBER ON NHTSA. IT IS A USED CAR, I AM NOT SURE WHETHER THE FORMER USER RESPONDED THE RECALL BEFORE. EVEN IF THIS CAR WAS RECALLED...

ON BMW WITH THE N62 4.4L V8 ENGINE THERE'S AN OIL LEAK ON THE ALTERNATOR BRACKET THAT LEAKS FOR A WHILE UNTIL IT IS INSPECTED AND FOUND IT LEAKS OIL ON THE STEERING COMPONENTS I THINK CAUSING THE STEERING COMPONENTS TO DETERIORATE AFTER A WHILE CAUSING A SAFETY ISSUE. THE OIL LEAK EVENTUALLY HAPPENS TO ALL N62 4.4L V8 ENGINES. *TR
