2016 Toyota Prius

VEHICLE FEELS LIKE IT WANTS TO GO FORWARD AS SOON AS THE GAS ENGINE TURNS ON TO CHARGE THE HYBRID BATTERY WHEN IT IS STATIONARY, IS IN PARK GEAR WITH THE FOOT PARKING BRAKE FULLY ON AND ON A FLAT SURFACE. WHEN THE CAR IS RUNNING OFF OF BATTERY MODE AND THE BATTERY BECOMES DEPLETED THE GAS ENGINE TURNS ON TO CHARGE THE HYBRID BATTERY, YOU CAN FEEL THE CAR SENDING POWER TO THE WHEELS FOR A SLIGHT TWO SECONDS AND CAN ALSO HEAR THE BRAKES CREAKING AS A RESULT OF THE ENGINE FEELING ENGAGED TO THE WHEELS EVEN WHEN THE PARK GEAR (/BUTTON) IS SELECTED. IT HAPPENS ALL THE TIME AND NOT SURE WHY IT WOULD DO THAT WHILE IN PARK. IF A PARKING BRAKE FAILURE WAS TO HAPPEN WHAT WOULD HAPPEN WHEN THE ENGINE TURNS ON TO CHARGE THE BATTERY AGAIN? WILL IT CREEP FORWARD OR WHAT? JUST THOUGHT THIS WAS A CONCERN SINCE I HAVE NOT EXPERIENCED THIS WITH NON HYBRID CARS.

WHILE DRIVING THE VEHICLE STARTED TO SHAKE FROM UNDERNEATH FIERCELY, I CALLED MY MOTHER WHO CAME AND PICKED UP THE CAR SHE TURNED AROUND AND WENT BACK TO MY RESIDENCE, WHILE ATTEMPTING TO PARK IN THE GARAGE THE CAR STARTED TO ROLL DOWN THE DRIVEWAY AND THE BRAKES WOULDN'T WORK, THE CAR LANDED ON THE STREET. CITY OF LANCASTER CA

ON FRIDAY, OCTOBER 21, 2016 WHILE DRIVING OVER A POTHOLE I PRESSED ON THE BRAKE. THE CAR SLOWED BUT ALL OF A SUDDEN THE BRAKE SUDDENLY DEPRESSED EVEN FURTHER DOWN AND THE CAR JERKED AND SEEMED TO STALL BEFORE PUSHING FORWARD. I HAD BEEN PRESSING THE BRAKE AS FAR DOWN AS IT WOULD GO AND IT SEEMED AS IF THERE WOULD BE SOME KIND OF BRAKE FAILURE. ON OCTOBER 31, 2016 WHILE DRIVING OVER ANOTHER POTHOLE, I AGAIN STEPPED ON THE BRAKE AND SUDDENLY THE PEDAL AGAIN DEPRESSED FURTHER DOWN AND THERE WAS A CREAKING AND SQUEALING SOUND. THEN ON NOVEMBER 4, 2016 WHILE GOING OVER A POTHOLE, THERE WAS A SQUEALING AND CREAKING SOUND BUT NOT A SUDDEN ADDITIONAL DEPRESSION OF THE BRAKE PEDAL. ALL THESE INCIDENTS HAPPENED ON SALT LAKE BLVD. OR KAMEHAMEHA HIGHWAY AND PASSES UNDER THE FIXED GUIDEWAY FOR HAWAII'S RAIL SYSTEM. THE ROAD IS EXTREMELY BUMPY AND FULL OF POTHOLES.

AS I TOOK A HIGHWAY EXIT, FOLLOWING BEHIND OTHER CARS DOING THE SAME, MY PRIUS REFUSED TO BRAKE EFFICIENTLY WHEN ANOTHER CAR ABRUPTLY INVADED OUR LINE. IT FELT AS IF THE BRAKES MADE A SLIGHT RELEASE OR COULDN'T REACH A FULL STOP. I HAD ENOUGH SPACE TO STOP, AND I PRESSED THE BRAKES ON TIME BUT THERE WAS ALMOST NO BRAKE REACTION AND I CRASHED INTO THE TRUCK IN FRONT OF ME. I WAS PROBABLY GOING 20-30 MPH, SOMEWHERE IN THE MIDDLE... SO NOT EVEN THAT FAST. BEST PART IS THAT THE AIRBAGS DIDN'T INFLATE, EVEN THOUGH THE CAR WAS ALMOST TOTALED. THIS FEELS EXPLAINABLE TO ME... I HAD IT FOR ONLY TWO MONTHS THUS FAR. I DO NOT RECOMMEND THIS CAR TO OTHERS.

WHEN GENTLY APPLYING BRAKES FOR A STOP LIGHT, AND THE RIGHT WHEEL HITS A 1 AND 1/8 INCH DEEP DEPRESSION IN THE ROAD, THE BRAKES FEEL LIKE THEY MOMENTARILY RELEASE. THE DEPRESSION IS FOR A 9 INCH DIAMETER CITY WATER COVER, AND THE OVERALL DIAMETER OF THE DEPRESSION IS 12 INCHES, AND IT IS 1 AND 1/8 INCHES DEEP. THIS CAN BE REPLICATED AT THIS LOCATION AND WE HAVE ALSO NOTICED THE SAME THING HAPPENING ELSEWHERE IN TOWN.
