Car was driving fine one day and then while driving down the interstate I had the Pre collision system malfunction error, Brake light came on, Cruise will not operate, ABS light is on. After much research it seems Prius V has a common issue with brake booster faulting.

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.
I HAVE OWNED SEVERAL TOYOTA VEHICLES OVER THE YEARS - A TERCEL, A RAV4, A TACOMA AND A PRIUS V. RECENTLY I WAS HIT WITH A $1680 + REPAIR TO MY 2016 PRIUS V DUE TO 'RODENT DAMAGE' TO MY WIRING.

I HAVE OWNED SEVERAL TOYOTA VEHICLES OVER THE YEARS - A TERCEL, A RAV4, A TACOMA AND A PRIUS V. RECENTLY I WAS HIT WITH A $1680 + REPAIR TO MY 2016 PRIUS V DUE TO 'RODENT DAMAGE' TO MY WIRING. THIS INCLUDED DAMAGE TO 3 OUT 4 BRAKE LINES, AN O2 SENSOR LINE, A FUEL LINE SENSOR AND POSSIBLY A FUEL PUMP WIRING HARNESS. THE CHECK ENGINE LIGHT CAME ON WHILE DRIVING AT 60MPH. I WAS DRIVING ON 1 WORKING BRAKE LINE!! MY CAR WAS IN THE TOYOTA SHOP FOR 3 DAYS. I'VE READ THAT TOYOTA DENIES RESPONSIBILITY FOR USING WIRING THAT ATTRACTS RODENT CHEWING. I HAVE BEEN FORCED TO TAKE THIS LOSS OF USE AND DAMAGE TO MY AUTO INSURANCE POLICY AND AM EXTREMELY CONCERNED THAT I WILL FACE THIS TYPE OF DAMAGE IN THE FUTURE WITH MORE CATASTROPHIC RESULTS LIKE AN ACCIDENT. THIS POSSIBILITY MAKES THE OWNERSHIP OF A MY PRIUS FINANCIALLY AND PRACTICALLY UNTENABLE!!! I CAN'T DEPEND ON MY PRIUS TO BE ABLE TO DRIVE ME TO MY WORK OR AND ANY OTHER DESTINATION SAFELY IF THE DESIGN OF THIS VEHICLE MAKES THE WIRING ACCESSIBLE TO RODENTS. I CAN'T KILL EVERY RODENT THAT MAY ENCOUNTER MY CAR IN EVERY LOCATION I PARK OR DRIVE MY CAR!! SINCE THIS HAS HAPPENED NOT ONLY TO ME BUT ALSO OTHER TOYOTA OWNERS, I WANT TO KNOW WHAT TOYOTA IS DOING TO PREVENT AND/OR CORRECT THIS PROBLEM? I'M HAVING TO PAY FOR INSTALLING NEW WIRING, WHICH UNLESS THE TOYOTA SERVICE CENTER DOING THE REPAIR DOES SOMETHING TO PREVENT THIS FROM HAPPENING AGAIN, THE WIRING WILL STILL BE SUBJECT TO THE SAME DESTRUCTION DUE TO TOYOTA'S BAD DESIGN AND/OR INFERIOR MATERIALS THAT PERMIT RODENT DAMAGE.
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 IN…

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.
