2010 BMW 550I

PURCHASED CAR TWO YEARS AGO AND DRIVETRAIN MALFUNCTION CONTINUES TO LIGHT CONTINUALLY COMES ON, VEHICLE BEGINS TO SHAKE UNCONTROLLABLY. I'VE HAD DRIVEN LEXUS VEHICLES FOR THE PRIOR 30 YEARS AND NEVER SPENT SO MUCH TIME AT THE DEALER TRYING TO RESOLVE THE SAME PROBLEM OR ANY MECHANICAL / ELECTRICAL PROBLEMS. SWITCHING TO BMW WITHIN THESE PAST TWO YEARS HAVE LITERALLY INTERRUPTED MY LIFE, COST ME TIME AND MONEY AS THIS VEHICLE WAS IN THE REPAIR SHOP (DEALER) FOR MORE THAN 70 DAYS WITHIN TWO YEARS (DEALER SPENT JUST AS MUCH TIME WITH THE CAR AS I). AFTER ALL THE REPAIRS THE FAITHFUL DRIVETRAIN MALFUNCTION ENTERS MY LIFE YET AGAIN. CAN YOU DO SOMETHING ABOUT THIS MAJOR COMPONENT IN THIS CAR. AFTER PURCHASING FOR CASH I THOUGHT I WOULD NOT NEED TO PURCHASE ANOTHER CAR FOR AT LEAST 5-6 OR MORE YEARS BUT ONCE AGAIN I FIND MYSELF HAVING TO NOW BUY A RELIABLE CAR. IF I KNEW BMW VEHICLES WERE THIS MUCH TROUBLE, I WOULD HAVE SAVED AN ENORMOUS AMOUNT OF CASH BY FINANCING INSTEAD EXPENDING THAT AMOUNT UPFRONT ONLY TO FIND MYSELF "LIVING" AT THE DEALERSHIP. SADDEST PART IS YOUR ORGANIZATION HAS A SAFETY RECALL FOR THIS PROBLEM BUT ONLY THE 2011-12 BMW 550I GRAN TURISMOS AND I HAVE THE 2010. I GUESS "AFTER" I PAY FOR THE REPAIR THEN YOU WILL INITIATE A RECALL TO INCLUDE THIS YEAR AS WELL (SAME CAR AS OTHERS, EXPERIENCING THE EXACT SAME PROBLEM, BUT ONE YEAR MAKING THE DIFFERENCE). CAN YOU PLEASE HELP.
