NHTSA Complaint #10552007 — 2008 TOYOTA PRIUS

I HAVE A TOYOTA PRIUS AND IT IS USED AS A TAXI IN SAN FRANCISCO. I HAD NOTICED A FEW TIMES THAT THE ENGINE REVS UP WHILE I WAS AT STOP AND THE BATTERY WAS FULLY CHARGED. IT WAS LIKE THE ENGINE PULSE. IDLE TO HIGH REV AND IDLE AGAIN FOR A FEW TIMES AND THAT HAPPENED FOR ABOUT 2 WEEKS WHILE ON THE ROAD. THE VEHICLE STARTED TO ACCELERATE BY ITSELF AT THE FIRST WEEK OF NOV 2013 AND HAPPEN AGAIN ON HIGHWAY 101 SOUTH IN MILL VALLEY CA AROUND 8 PM. I HAVE CALLED CITY TOYOTA AND EXPLAINED ABOUT IT BUT THE SERVICE DEPARTMENT JUST TOLD ME TO GET APPOINTMENT TO CHECK IT UP. AS I ASSUME MYSELF AS WELL EXPERIENCED DRIVER WITH 25 YEARS OF DRIVING MULTI TYPE OF VEHICLES, IT IS NOT DRIVER ERROR NOR THE PEDAL NOR THE FLOOR MATS. IT IS MECHANICAL OR ELECTRICAL PROBLEM. *TR
