TRANSMISSION SKIPPED, ESPECIALLY WHEN COMING TO A STOP...IT WAS DIAGNOSED AND "REPAIRED" BY REPLACING THE "MECHATRONICS" IN THE VEHICLE. NOW, IT HAS OCCURRED AGAIN, AND THEY CLAIM NOW THAT IT IS THE FAILURE OF THE DOOR OPENING SYSTEM, INSTALLED BY BMW, THAT'S CAUSING THE BATTERY TO "LEAK", THEREFORE CAUSING THE TRANSMISSION TO MALFUNCTION..I DON'T UNDERSTAND THE CONNECTION BETWEEN THE TWO ITEMS, AND IF SO THIS COULD BE EXTREMELY DANGEROUS TO MYSELF AND FAMILY. THE CAR COULD COME TO A SUDDEN STOP AT ANY TIME AND CAUSE US TO GO FORWARD, AND POSSIBLE TO DO SERIOUS INJURY OR DEATH, OR THE BATTERY COULD EXPLODE AGAIN CAUSING SERIOUS INJURY. I WOULD LIKE TO SHOW YOU THE RECORDS THEY PROVIDED TO ME, AND BE ASSURED THAT THIS PROBLEM ISN'T ONE THROUGHOUT THEIR VEHICLES, LIKE A BOMB READY TO GO OFF AT ANY TIME. *TR
