WHEN DRIVING BETWEEN 0 TO 5 MILES PER HOUR I PRESSED ON THE ACCELERATOR PEDAL WHILE THE AUTO WAS EITHER ON LEVEL SURFACE OR AT THE BEGINNING OF A SMALL INCLINE THE AUTO DID NOT MOVE FORWARD. THEN I SHIFTED THE AUTO INTO REVERSE AND STEPPED ON THE ACCELERATOR PEDAL AND THE AUTO DID NOT MOVE BACKWARDS. I THEN TURNED THE AUTO OFF WITH THE AUTO SHIFTED INTO PARK. THEN I RESTARTED THE AUTO AND SHIFTED INTO DRIVE AND PRESSED ON THE ACCELERATOR PEDAL AND THE AUTO DID MOVE FORWARD. THE SAME DAY I BROUGHT THE AUTO INTO THE JEEP DEALER WHOM I LEASED THE AUTO FROM JUST FIVE DAYS EARLIER, TO IDENTIFY AND FIX THE DEFECT CAUSING THE AFOREMENTIONED PROBLEM. ON MONDAY 11/8/10 THE DEALER INFORMED ME THE VEHICLE IS OPERATING AS DESIGNED AND THEY FOUND NOTHING WRONG WITH IT, AND THEY RETURNED THE VEHICLE TO ME. I AM CONCERNED THAT THE DEFECT WHICH CAUSED THE AFOREMENTIONED PROBLEM ON 11/6/10 COULD CAUSE REOCCURRENCE(S) OF THE AFOREMENTIONED PROBLEM (EVEN AT HIGHER SPEEDS)
