2011 BMW 135I US Engine Problems

VEHICLE WILL "JOLT" FORWARD. THIS ISSUE HAS HAPPENED TO ME OVER 100 TIMES. THE ISSUE IS BEST DESCRIBED LIKE THIS. I WILL DRIVE THROUGH A FAST FOOD DRIVE-THRU LINE AND THERE WILL BE 1 OTHER VEHICLE IN FRONT OF ME. I WILL PULL UP AND BRAKE TO A COMPLETE STOP TO ORDER.

MY FIRST ISSUE WAS BACK IN FEBRUARY WITH A BLOWN CHARGEPIPE. THE CAR JUST LEFT ME STRANDED 50 MILES FROM HOME AND IT HAD TO BE TOWED BACK. ON JULY IT LEFT ME STRANDED AGAIN, IT WAS A BROKEN VANOS BOLT IN THE ENGINE. DURING THIS VISIT, I TOLD TO THE SA THE HARD TIME MY CAR WAS HAVING WHEN CRANKING EVERY MORNING FOR THE PAST TWO WEEKS. I GOT THE CAR BACK, AND IT SEEMED THAT EVERYTHING WAS FIXED, BUT THE BATTERY. I WAS TOLD THAT THE BATTERY WAS DISCHARGED DUE TO OVER CRANKING WHEN I GOT STRANDED. TWO WEEKS LATER, THE CAR GAVE ME AN ENGINE WARNING YELLOW LIGHT. IT RESULTED TO BE THAT THE INTAKE VANOS MODULE FAILED. THEY...
