I PURCHASED THE VEHICLE NEW IN 2025 AND I HAVE BEEN EXPERIENCING BRAKE FAILURE ISSUES EVERY TIME I ATTEMPTED TO BRAKE OVER EITHER A POTHOLE, A SLICK SURFACE LIKE A METAL SHEET AT ROAD CONSTRUCTION OR WET ROADS THE BRAKE WOULD FAIL. ALL THE RED WARNING SIGNS WOULD COME ON IN THE DASHBOARD AND THE BRAKES WOULD MAKE THAT LOUD HORRIBLE NOISE. I LOVE MY PRIUS, I DON'T WANT TO GET RID OF IT. I WAS HOPING TOYOTA MOTORS WOULD HAVE A FIXED FOR THE BRAKING SYSTEM BY NOW AS THIS IS VERY UNSAFE SPECIALLY INEXPERIENCED DRIVERS. MY GOAL IS TO PASS THIS CAR TO MY TEENAGE DAUGHTER WHEN SHE GOES TO COLLEGE IN 2021, BUT THIS MAY NOT BE POSSIBLE IF TOYOTA DOESN'T TO UP WITH A SOLUTION TO THE PROBLEM.

THE BRAKES ON MY 2015 PRIUS TOTALLY FAILED AND I HAD TO SWERVE TO AVOID CRASHING INTO THE CAR STOPPED IN FRONT OF ME. I'VE BEEN DRIVING FOR MORE THAN 30 YEARS AND HAVE NEVER EXPERIENCED ANYTHING LIKE THIS. IT WAS TERRIFYING. TO WIT: I WAS DRIVING ABOUT 20 M.P.H. ON CITY STREETS IN LONG BEACH, CALIFORNIA, IN APRIL 2019. AS I DROVE OVER A BRIDGE, TRAFFIC WAS COMING TO A STOP AT A RED LIGHT 200 YARDS IN FRONT OF ME. I DROVE OVER A NARROW METAL PLATE--THERE ARE SEVERAL ON THE BRIDGE--AND HIT THE BRAKES, BUT MY CAR DIDN'T SLOW. A WARNING LIGHT FLASHED--A STABILITY CONTROL LIGHT, I BELIEVE, DUE TO THE METAL PLATE. I PRESSED THE BRAKES TO THE FLOOR AS MY CAR ROLLED DOWNHILL ON PAVEMENT. MY CAR DID NOT SLOW AT ALL. I LOOKED IN THE DRIVER SIDE MIRROR AND SAW THAT THE LANE TO MY LEFT WAS CLEAR, SO I SWERVED INTO IT WITH MY FOOT ON THE BRAKES. THE CAR SLOWLY CAME TO A STOP WELL BEYOND WHERE I SHOULD HAVE STOPPED HAD MY BRAKES WORKED PROPERLY. THE INCIDENT WAS SO TERRIFYING THAT I HAD TO PULL OVER TO COLLECT MYSELF. MY BRAKES WORKED PROPERLY AFTER THAT. A FEW DAYS LATER, I TOOK MY CAR TO PENSKE TOYOTA IN DOWNEY, CALIFORNIA, WHERE I BOUGHT THE CAR, AND TOLD A SERVICE AGENT WHAT HAPPENED. I ASKED HIM TO FIX THE PROBLEM. AFTER SERVICE TECHNICIANS INSPECTED THE BRAKES THAT DAY, I WAS TOLD THE BRAKES APPEARED TO BE FINE AND, BARRING A RECALL, NOTHING COULD BE DONE. I'VE BEEN DRIVING THE CAR SINCE THEN, BUT I'VE WORRIED THAT THE BRAKES COULD FAIL AGAIN. THEN I SAW THE JAN. 3, 2020 ARTICLE BELOW. AS A RESULT, I'VE RENTED A CAR AND HAVE STOPPED DRIVING MY PRIUS. THIS IS A TERRIFYING, LIFE-THREATENING PROBLEM THAT NEEDS TO BE ADDRESSED NOW.

THE ENGINE IMMEDIATELY RACED AND THE CAR BEGAN TO ACCELERATE AT HIGH SPEED. I STOMPED ON THE BRAKE PEDAL AND THE CAR KEPT MOVING. THE SOUND OF THE ENGINE WAS LOUD ENOUGH THAT PEOPLE IN NEARBY HOUSES HEARD IT. MY CAR WOULD NOT SLOW WITH MY EFFORTS TO BRAKE. I TRIED TO SHIFT INTO NEUTRAL AND PARK BUT THE CAR DID NOT SLOW DOWN. IT RACED ACROSS THE STREET AND PLOWED DIRECTLY INTO A NEIGHBOR'S STONE WALL. MY CAR BECAME WEDGED BETWEEN THE WALL AND A LARGE TREE. I HAD TO EXIT THE VEHICLE FROM THE PASSENGER SIDE AS THE DRIVER'S DOOR WAS PRESSED AGAINST THE TREE. AFTER THE COLLISION, INTERIOR LIGHTS WERE NON-FUNCTIONING EVEN WHEN THE DOOR WAS PROPPED OPEN. THE CAR WOULD HAVE CRASHED THROUGH THE HOUSE IF IT HAD NOT BEEN STOPPED BY THE WALL AND TREE.

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
