ON DEC. 2, 2014, I WAS ENTERING A WALGREEN'S PARKING LOT IN MY LEASED 2014 LEXUS IS 250, WHICH I HAD OWNED FOR ONLY 4 MONTHS WITH 1740 MILES. MOVING AT 5MPH OR LESS, I TURNED THE WHEEL TO ENTER A PARKING SPACE, WHEN THE CAR SUDDENLY ACCELERATED AND TOOK OFF. I PRESSED THE BRAKES TO THE FLOOR AND NOTHING HAPPENED. THE CAR JUMPED UP OVER A PLANTED MEDIAN FILLED WITH BUSHES, TREES AND A PHONE POLE. THE FRONT TIRES BECAME LODGED IN MUD AND THAT STOPPED THE CAR. I MISSED THE TELEPHONE POLE BY LESS THAN 1 FOOT. LUCKILY, I HAD AN INDIVIDUAL WITNESS THE ENTIRE EPISODE. I TELEPHONED LEXUS EMERGENCY SERVICES AND LEXUS CUSTOMER RELATIONS IMMEDIATELY. THE CAR HAD TO BE REMOVED FROM THE MEDIAN BY A TOW COMPANY AND WAS TAKEN TO THE DEALERSHIP WHERE PURCHASED. AFTER EXAMINING THE CAR FROM DEC. 3-DEC. 10, THE DEALERSHIP CLAIMS THERE IS BODY DAMAGE BUT NO MECHANICAL PROBLEM WITH THE CAR. THE DEALER CALLED ON DEC. 10 SAYING THE CAR WAS READY TO BE PICKED UP. I NOTED INACCURATE DATA IN THE SERVICE REPORT FROM WHAT I TOLD THE SERVICE MANAGER ORIGINALLY, AND I WAS GIVEN NO INFORMATION AS TO FOLLOW-UP ON THIS MATTER. I WAS SIMPLY TOLD THAT LEXUS CORPORATE HAD BEEN OUT TO SEE THE UNDERSIDE DAMAGE TO THE VEHICLE.(FRONT BUMPER, PAINT, CRACKS ON BASE OF BUMPER), AND THAT I WOULD HEAR FROM THEM IN 10 DAYS. I CALLED LEXUS CORPORATE AND WAS TOLD THAT THE MATTER IS NOW IN THE LEGAL DEPT. AND THAT IT WOULD BE FAR MORE THAN 10 DAYS FOR A RESPONSE. RATHER, I COULD EXPECT A CALL IN 4/6 WEEKS O
