I HAVE A 2003 FORD EXPLORER. I HAVE HAD SEVERAL INCIDENTS OF IT NOT EASILY CHANGING FROM PARK TO REVERSE, AND REVERSE TO PARK. LAST NIGHT, I WAS UNLOADING SOME ITEMS FROM THE EXPLORER. THE CAR WAS IN PARK, AND THE EMERGENCY BRAKE WAS ENGAGED. I WAS STANDING IN THE RIGHT SIDE PASSENGER DOORWAY. I REACHED OVER TO TURN OFF THE IGNITION. UPON TURNING IT OFF, THE EXPLORER IMMEDIATELY BEGAN TO ROLL INTO REVERSE. MY MOTHER WAS SITTING IN THE BACKSEAT AT THIS TIME AS WELL AS MY TWO BABIES, WHO WERE STRAPPED IN THEIR CAR SEATS. MY DRIVEWAY IS AN INCLINE, SO THE EXPLORER ROLLED BACKWARDS. I TRIED TO RUN WITH IT AS I WAS TRAPPED IN THE DOORWAY. THE EXPLORER GAINED SPEED GOING DOWN THE DRIVEWAY, CAUSING ME TO BE KNOCKED DOWN, UNSURE OF WHETHER OR NOT I WAS ABOUT TO BE RUN OVER, OR WHETHER MY MOM AND CHILDREN WERE GOING TO BE INJURED. I WAS THROWN DOWN, LANDED ON MY BUTTOCKS WHICH HAS CAUSED SEVERE BRUISING, HIT MY HEAD ON THE CONCRETE, AND WAS LEFT WITH PAINFUL, OPEN CUTS ON MY LEFT ARM. MY MOTHER WAS TOSSED ABOUT CAUSING PAIN TO HER BACK. MY KIDS WERE THANKFULLY RESTRAINED IN THEIR CAR SEATS. THEY ROLLED BACKWARD INTO A NEIGHBOR'S YARD, THEN PROCEEDED TO ROLL FORWARD BACK ACROSS THE STREET INTO MY YARD. WHEN THE CAR FINALLY STOPPED, THE EMERGENCY BRAKE WAS STILL ENGAGED, AND THE GEAR SHIFT WAS STUCK BETWEEN PARK AND REVERSE. IT WOULD NOT COME OUT OF THIS POSITION. IT TOOK QUITE A LOT OF WORK TO GET THE CAR TO GO INTO REVERSE OR DRIVE SO THAT THE EXPLORER COULD BE PROPERL
