2009 ACURA RL Power Train Problems

MY HUSBAND DROVE ONTO A SLOPED DRIVEWAY (UPHILL) AND LEFT THE CAR RUNNING, GOT OUT AND RANG THE DOORBELL TO OUR DAUGHTER'S HOUSE TO SEE IF ANYONE WAS HOME. THEY ANSWERED THE DOOR AND HE CAME BACK TO THE CAR AND MOTIONED FOR ME TO GET OUT OF CAR AND COME INTO HOUSE. HE REMEMBERED HE HAD LEFT THE CAR RUNNING, SO AS I GOT OUT OF THE FRONT PASSENGER SEAT, HE REACHED IN AND TURNED THE IGNITION OFF. I TURNED TOWARD THE BACK OF CAR TO GET SOMETHING OUT OF THE BACK SEAT. THE FRONT PASSENGER DOOR WAS STILL OPEN ALL THE WAY. THE CAR STARTED ROLLING BACKWARD DOWN THE DRIVEWAY, I TRIED TO RUN BUT THE DOOR HIT ME KNOCKED ME FACE DOWN ON THE ASPHALT OF THE STREET, AND THE BOTTOM OF THE OPEN FRONT DOOR SCRAPED OVER ME, ABRADING MY HEEL, BACK, AND LACERATING MY HEAD....
