I AM WRITING THIS BECAUSE OF THE RECENT TRANSMISSION SHIFTER RECALL REGARDING MY 2014 JEEP GRAND CHEROKEE. ON APRIL 9, 2015, AT APPROXIMATELY 2:00 A.M., I STOPPED AT THE POST OFFICE TO MAIL A LETTER. I PLACED THE ELECTRONIC VEHICLE GEAR SHIFTER INTO 'PARK'. IT ACTUALLY WENT INTO REVERSE. AS I STEPPED OUT OF THE VEHICLE, MY FOOT BEGAN TO SLIP. I THOUGHT I HAD STEPPED ONTO SOME OIL ON THE PARKING LOT. I PLACED MY OTHER FOOT ONTO THE PAVEMENT TO CATCH MY BALANCE. IT BEGAN TO SLIP, ALSO. IN THE CONFUSION, I WAS UNABLE TO DETERMINE WHETHER THE VEHICLE WAS MOVING FORWARD OR REVERSE. I STILL HAD A HOLD ON THE DOOR AND THE STEERING WHEEL. AS I TRIED TO PULL MYSELF BACK INTO THE VEHICLE, THE STEERING WHEEL TURNED. AT THAT POINT, AND SINCE THE DOOR WAS WIDE OPEN, I DECIDED TO DROP TO THE PAVEMENT TO MOVE AWAY FROM THE MOVING VEHICLE. WHEN I DID, THE FRONT LEFT WHEEL ROLLED OVER MY RIGHT LEG. MY LEG MUST HAVE BEEN IN A FOLDED POSITION. THE WHEEL ROLLED ONTO THE INNER-UPPER PART OF MY LOWER LEG, MISSING THE KNEE, AND OFF THE OUTER-LOWER PART OF MY UPPER LEG. THE PAIN SET IN. I WAS ABLE TO GET UP, CHASE DOWN THE VEHICLE, GET IN, AND STOP IT BEFORE IT CRASHED INTO ANYTHING. I SAT IN THE VEHICLE FOR A WHILE UNTIL SOME OF THE PAIN SUBSIDED A BIT, DROVE BACK TO THE ORIGINAL PLACE AT THE POST OFFICE AND PARKED IT. I LOST THE LETTER I WAS MAILING AND SEARCHED FOR IT. I WENT HOME, TOOK THREE ASPIRIN AND A SHOT OF WHISKEY, AND WATCHED TELEVISION FOR A WHILE UNTIL I COULD SLEEP.
