2013 BMW 335XI Fuelpropulsion System Problems

IN A LEFT-HAND TURNING LANE OF A CITY STREET, INTENDING TO MAKE A LEFT TURN ON A GREEN LIGHT AT A CONTROLLED INTERSECTION, MY CAR WAS STATIONARY AT IDLE & IN NEUTRAL AT A COMPLETE STOP UNTIL ON-COMING TRAFFIC CLEARED INTERSECTION. FROM A DEAD STOP IN 1ST GEAR (STICK SHIFT), I STARTED A LEFT TURN - SUDDENLY, UNEXPECTEDLY & UNINTENTIONALLY THE VEHICLE RAPIDLY & UNCONTROLLABLY ACCELERATED TO 30 TO 40 MPH. I CLUTCHED OUT OF GEAR, SLAMMED ON THE BREAKS, BUT COULD NOT SLOW THE VEHICLE. THE VEHICLE SUBSEQUENTLY JUMPED A CURB AND COLLIDED HEAD-ON WITH A TELEPHONE POLE. SEAT BELT WORKED AND AIR BAG DEPLOYED. CAR WAS TOWED. I WAS TRANSPORTED BY EMS TO AN EMERGENCY ROOM TO EVALUATE FOR INJURIES.
