NHTSA Complaint #11123312 — 2012 BMW X5

I WAS DRIVING MY BMW X5 AND OUT OF NOWHERE AN "ENGINE MALFUNCTION WARNING LIGHT" CAME UP ACCOMPANIED BY AN ENGINE OVERHEATING, I IMMEDIATELY PULLED OVER AND CALLED A TOW-TRUCK WHO TOOK MY X5 TO THE NEARS BMW DEALER. THE TECHNICIAN STATED IT WAS THE IVM AND THE CHARGE AIR PIPE THAT NEEDED TO BE REPLACED, AFTER SPENDING $1,500 ON THE 2 ITEMS, I DROVE OUT OF THE DEALER AND LESS THAN A MILE DOWN THE ROAD, THE SAME "ENGINE MALFUNCTION AND VEHICLE OVERHEATING LIGHT" CAME BACK UP. CALLED THE DEALER AND ANOTHER TOW-TRUCK PICK UP MY X5, THEN I REQUESTED TO SPEAK WITH THE SHOP MANAGER WHO INFORMED ME THE PROBLEM WITH THE X5 WAS NEVER PERTAINING TO THE IVM OR CHARGE AIR PIPE, AS THEY MISS OVERLOOKED THE DIAGNOSIS WHICH STATED THE DME WAS NOT WORKING. THEY CHANGE THE DME AND ANOTHER $2,000 WAS CHARGED, AFTER IT WAS REPAIR AND I DROVE AWAY, THE SAME ENGINE MALFUNCTION LIGHT AND VEHICLE OVERHEATING LIGHT CAME UP, CALLED THE DEAELR AND THEY TOLD ME THAT AFTER CHANGING THE DME, THE NEW DIAGNOSIS STATED THE WATTER PUMP NEEDED TO BE REPLACED AND THIS WAS THE PART THAT WAS CREATING THE ENGINE MALFUNCTION AND OVERHEATED VEHICLE WARNING TO COME UP. I ENDED UP CHANGING THE WATER PUMP AND OTHER VEHICLE PARTS, THAT DID NOT NEEDED TO BE CHANGED AND NOW A RECALL FOR THE WATER PUMP CAME OUT. ON THE MEANTIME, I SPENT ALMOST $4,000.00 ON REPAIRS WHEN EVERYTHING COULD HAVE BEEN DONE IF THEY WOULD HAVE CONDUCTED THE WATER PUMP RECALL. WHO CAN REIMBURSE ME THE AMOUNT OF MONEY PAID? I SENT THE ORIGINAL DME TO SEE IF IT WAS DAMAGE, AND THEY CAME BACK STATING IT WAS NOT DAMAGE AT ALL, THEREFORE THE PROBLEM WAS THE WATER PUMP AND NOT THE DME, OR IVM OR CHARGE AIR PIPE. PLEASE HELP!!!
