2016 TOYOTA PRIUS V Engine Problems

I PREVIOUSLY SENT IN A COMPLAINT BUT THERE HAVE BEEN DEVELOPMENTS AND I NEEDED TO EXPLAIN MORE CLEARLY. OUR TOYOTA HAS LESS THAN 18,000 MILES AND HAS BEEN VERY WELL TAKEN CARE OF. DESPITE THIS, OUR VEHICLE HAS NOT BEEN IN OPERATION SINCE EARLIER THIS MONTH. IT STARTED BY FLASHING WARNING LIGHTS 2 WEEKS AGO AND THEN WOULDN'T START UP. SATURDAY WHEN I OPENED THE DRIVER DOOR TO GET SOMETHING OUT OF THE INOPERABLE VEHICLE, THIS INITIATED A VERY LENGTHY TERRIBLE SOUND COMING FROM UNDER HOOD ON DRIVER'S SIDE. IT SOUNDED LIKE SOMETHING WOULD EXPLODE UNDER THE HOOD. THIS HORRIBLE PROCESS APPEARANTLY DRAINED THE WHOLE BATTERY. IT HAS ABSOLUTELY NO SIGNS OF LIFE NOW. ALL OF THIS HAPPENED WHILE THE VEHICLE WAS STATIONARY.

WHILE PARKING MY VEHICLE AND SLOWING DOWN TO ENTER A PARKING SPACE, I EASED OFF THE BRAKE TO PULL INTO THE SPACE WHEN I HEARD THE ENGINE REV LOUDLY AND THEN THE CAR ACCELERATED AND CONTINUED TO ACCELERATE DESPITE ATTEMPTS TO PUMP THE BRAKES, RELEASE THE BRAKES WITHOUT TOUCHING ANY PEDAL AND ALSO TRYING TO PUT THE TRANSMISSION INTO PARK. THE VEHICLE WOULD NOT STOP AT ALL. I WAS AFRAID FOR MY LIFE AND TRIED EVERYTHING TO AVOID OTHER VEHICLES AND PEDESTRIANS AS THE CAR ACCELERATED GREATLY. I STEERED THE CAR TO TRY AND AVOID A SLIGHT EMBANKMENT AND CURVE BUT WITH THE RAPID SPEED OF THE CAR, IT BECAME HARD TO MANEUVER THE CAR. THE VEHICLE JUMPED THE CURB STRIKING A TREE AND THEN A CONCRETE POST. THE CAR CAME TO REST ON ITS SIDE AFTER IMPACT. THE CAR WAS A TOTAL LOSS.
