2010 BMW 535XI Power Train Problems

TWO TIMES IN THE PAST FIVE DAYS MY 2010 BMW 535XI HAS SHUT DOWN. EACH TIME IT HAS MALFUNCTIONED(12/24/16 AND 12/29/16), THE AUTOMATIC DOWNSHIFT ACTIVATED). ONCE WHILE TRAVELING UP A HILL AT APPROXIMATELY 35 MILES PER HOUR AND ONCE WHILE TRAVELING IN EXCESS OF 55 MILES PER HOUR ON A VERY BUSY HIGHWAY. I WAS NOT ABLE TO RESTART THE VEHICLE AND HAD THE VEHICLE TOLLED TO A LOCAL GARAGE. SHORTLY AFTER ARRIVING THE TOW OPERATOR STARTED THE VEHICLE. IT STARTED WITHOUT HESITATION A SECOND TIME. I LEFT THE VEHICLE AT THE REPAIR SHOP AND PICKED IT UP FOUR DAYS LATER. IT HAS STARTED AND OPERATED AS BEFORE UNTIL DAY FIVE WHEN I WAS TRAVELING UPHILL AND IT INITIATED A DOWNSHIFT AND STOPPED OPERATING. EACH TIME THE FUEL PUMP FAILURE INDICATOR CAME ON. IT IS A SCARY FEELING, ESPECIALLY SINCE EACH TIME I WAS IN THE MIDST OF OTHER VEHICLES....

EXPERIENCING HARD BUMP WHEN BRAKING, HARD SHIFTS IN SPORT MODE, SLOW TO ENGAGE IN REVERSE AND HUNTING FOR THE RIGHT GEAR WHEN COASTING. THIS DELAYED AND JERKY RESPONSE PRESENTS A SEVERE DRIVING RISK AND DANGER AS THE VEHICLE BEHAVIOR IS UNPREDICTABLE AND INCONSISTENT. THESE ARE COMMON SYMPTOMS OF A KNOWN MECHATRONICS FAILURE, HOWEVER BMW REFUSES TO FIX THIS UNTIL A CODE IT THROWN. UNFORTUNATELY THE SAFETY OF MY FAMILY SHOULD NOT REQUIRE A CODE!!!!! *TR
