“BMW 750 I XDRIVE 2011 --EXCESSIVE ENGINE OIL CONSUMPTION AND OR BURNING. THE DESIGN OF THE VALVE STEM SEALS IS A MAJOR SAFETY PROBLEM DUE TO EXCESSIVE OIL CONSUMPTION.

“ABOUT 6 MONTHS AGO THE CAR STARTED SPUTTERING WHEN YOU ACCELERATE. I FOUND ONLINE THAT YOU CAN TAKE YOUR BMW 750LI XDRIVE IN FOR A CUSTOMER CARE PACKAGE ( THEY DID NOT CALL IT A RECALL BUT A CUSTOMER CARE PACKAGE.) I THOUGHT THIS WOULD CORRECT THE PROBLEMS BECAUSE THEY REPLACE SOME SENSORS AND VACUUM HOSE BUT THE PROBLEM IS STILL THERE. BMW DID A FULL DIAGNOSTIC AND SAID (REMOVE AND REPLACE ALL INJECTORS (X8), IGNITION COILS (X8),AND SPARK PLUGS (X8) (DURING THE INSPECTION FOUND THE VEHICLE MISFIRING) FINAL COST WILL RUN $6777.00 MY WARRANTY COMPANY WILL REFUSE TO PAY BECAUSE THEY WANTED TO KNOW WHAT WOULD YOU REPLACE ALL 8 INJECTORS AND ALL OF THE OTHER PARTS BECAUSE ALL 8 INJECTORS CANT BE BAD. THE WARRANTY COMPANY THINK BMW KNOW THEY HAVE A FAULTED INJECTION SYSTEMS AND TRYING TO UPGRADE AND CORRECT THE PROBLEM AT THE CUSTOMER EXPENSE. THE CAR BURN MAJOR OIL, BMW CLAIM THIS IS NORMAL.”
