NHTSA Complaint #10781917 — 2008 TOYOTA PRIUS

I WAS TRAVELING NORTHBOUND ON THE SAW MILL RIVER PARKWAY. EXITED ON THE NORTHBOUND TACONIC STATE PARKWAY RAMP. AFTER CROSSING THE TACONIC STATE PARKWAT OVERPASS. MY 2008 TOYOTA PRIUS (WITHOUT ANY INPUT FROM MY PART) TURNED LEFT AND ACCELERATED ONTO THE GRASSY AREA. EVEN THOUGH MADE MULTIPLE ATTEMPTS AT CORRECTING MY DIRECTION BY TURNING THE CAR TO THE RIGHT AND TO STOP THE CAR, NEITHER THE STEERING INPUTS OR ENGAGING THE BRAKES HAD ANY EFFECT ON THE VEHICLE. AFTER TRAVELING ALMOST THE ENTIRE WIDTH OF THE GRASSY AREA, THE CAR WAS CAUGHT BY A BRANCH ON THE GROUND, JUST BEFORE THE DRIVER SIDE OF THE CAR WOULD HAVE SLAMMED INTO A TREE. I THEN PROCEEDED TO TURN THE CAR OFF. WHEN I TURN THE CAR BACK ON, EVERYTHING WAS BACK TO NORMAL. THERE WAS NO ERROR MESSAGE FROM THE ECU DURING OR AFTER THE INCIDENT.
