I'M AN OWNER OF A 2010 PRIUS. TEN DAYS OR SO AFTER I PURCHASED THE CAR(IN JAN 2010), I EXPERIENCED A LOSS IN BRAKING WHICH RESULTED IN DAMAGE TO THE BUMPER. NUMEROUS!!!! ALMOST DAILY!!!! TIMES SINCE, EVEN AFTER THE RECALL FIX (DONE ON MY VEHICLE ON 3/10/10), I HAVE EXPERIENCED, NOT ONLY A LOSS OF BRAKING (USUALLY WHILE GOING OVER SOME LITTLE BUMP) BUT THE CAR ACTUALLY LURCHING FORWARD. QUITE DRAMATIC AND SCARY, ESPECIALLY IF THERE IS A STOP SIGN, INTERSECTION, A CAR OR A PERSON IN FRONT OF YOU. LAST THURS (11/10/11), THE ROAD SURFACE WAS WET, AND I BRAKED AND HAD NO, NONE , NADA BRAKES AND I REAR ENDED THE PERSON IN FRONT OF ME. I PAID FOR HER DAMAGE OUT OF MY OWN POCKET. I HAVE NOT FIXED THE DAMAGE DONE TO MY CAR. BRAND NEW ALL SEASON TIRES ON THE CAR, BY THE WAY. TODAY (11/14/11), AGAIN THE ROAD SURFACE WAS WET, I WAS BEHIND A CAR IN THE RIGHT LANE WHEN A CAR INAPPROPRIATELY BEGAN MERGING FROM A RAMP ON THE RIGHT, CAUSING THE CAR IN FRONT OF ME TO SUDDENLY SLOW DOWN. I BRAKED, AND AGAIN, NOTHING!!! I QUICKLY LOOKED IN MY SIDE VIEW MIRROR AND SAW I HAD CLEARANCE TO GO IN THE LEFT LANE, AND MANAGED TO AVOID CONTACT. 10 DAYS AFTER I PURCHASED THE 2010 PRIUS, I SAID I WANTED TO RETURN IT AND I SENT IN ALL THIS DOCUMENTATION CERTIFIED MAIL, BUT TOYOTA REJECTED EVERYTHING. THERE IS A DEFECT IN THIS CAR AND IT IS UNSAFE. *TR

WHEN I WAS PULLING INTO A PARKING SPOT, THE BRAKES FAILED AND THE VEHICLE ACCELERATED ON ITS OWN CAUSING ME TO RUN OVER THE CEMENT PARKING STOP AND CRASH INTO A CEMENT WALL. THE VEHICLE THEN BACK UP FROM THE CONCUSSION AND ACCELERATED ONCE AGAIN CAUSING ME TO CRASH TWICE. I FINALLY CAME TO MY SENSES AND SHUT THE VEHICLE OFF. I HAD BEEN NOTICING THE BRAKES FEELING STRANGE PRIOR TO THIS INCIDENT. THIS CAUSED $6,400 IN DAMAGE. TOYOTA WAS ALERTED, HAD THE VEHICLE INSPECTED AND CLAIM IT REVEALED NO EVIDENCE OF ANY SORT OF MALFUNCTION OR DEFECT. IN MY HEART, I KNOW THAT IS NOT TRUE. THIS WAS A VERY FRIGHTENING EXPERIENCE AND I DREAD THIS HAPPENING AGAIN. *TR

I GENTLY DRIVE MY 2010 TOYOTA PRIUS IN ECO MODE TO MAXIMIZE FUEL ECONOMY. EVERY WEEKDAY, SINCE JANUARY 2011, I SLOW ON A CERTAIN ROAD TO MAKE A RIGHT TURN. THE ROAD HAS A MANHOLE COVER RECESSED ABOUT 1 INCH INTO THE ROAD ALONG THE PATH OF MY PASSENGER SIDE TIRES. EVERY TIME I DRIVE OVER THIS MANHOLE COVER THE PRIUS COMPLETELY LOSES ABILITY TO BRAKE FOR ABOUT 1/2 SECOND, THEN BRAKING IS REESTABLISHED. THERE ARE OTHER SMALL BUMPS I DRIVE OVER AT OTHER PLACES WHICH HAVE THE SAME RESULTS TO THE PRIUS BRAKING SYSTEM. YESTERDAY (26 OCT 2011) SOMETHING DIFFERENT BUT POSSIBLY ASSOCIATED HAPPENED WHILE DRIVING OVER A BUMP. THIS TIME I WAS ACCELERATING AFTER HAVING MADE A RIGHT TURN FROM A COMPLETE STOP. WHILE STILL ACCELERATING AFTER THE TURN I SIGNALED LEFT AND PROCEEDED TO MERGE INTO THE LEFT HAND LANE. AS THE PRIUS RIGHT FRONT TIRE DROVE OVER THE REFLECTIVE LANE MARKER IMBEDDED IN THE ROAD SURFACE (THE MARKER STICKS OUT ABOUT 1/2 INCH FROM ROAD SURFACE) THE PRIUS WENT OUT OF CONTROL. THE CAR SUDDENLY AND SEVERELY PULLED HARD TO THE LEFT AND RAPIDLY SLOWED, I STRUGGLED AGAINST THE CARS ACTIONS TO AVOID HITTING THE RAISED CENTER MEDIAN. MY FIRST THOUGH WAS THAT I MUST HAVE HAD A COMPLETE AND INSTANTANEOUS BLOW OUT ON THE FRONT LEFT TIRE. MY REACTION WAS TO IMMEDIATELY REMOVE MY FOOT FROM THE ACCELERATOR. THEN AS I WAS FURTHER ASSESSING MY OPTIONS AND THE SURROUNDING TRAFFIC THE PRIUS REGAINED CONTROL AND I WAS ABLE TO CONTINUE DRIVING DOWN THE ROAD AS IF NOTHING HAD EVER HAPPENED. AS THE PRIUS REINSTATED CONTROL I HEARD A BEEP COME FROM THE DASHBOARD, HOWEVER I WAS NOT QUICK ENOUGH TO NOTICE IF ANY WARNING LIGHTS HAD ENGAGED DURING THE INCIDENT. WHEN I LOOKED AT THE DISPLAYS EVERYTHING APPEARED NORMAL. I ALSO CHECK THE CAR EXTERNALLY AND EVERYTHING APPEARED NORMAL. ALL INCIDENTS ARE ON HIGH QUALITY ROAD SURFACES WITH DRY PAVEMENT. DEALER INDICATES NO RECALLS. *TR

I BARELY AVOIDED HITTING A TRUCK IN FRONT OF ME (I WAS ABLE TO DRIVE AROUND). ROAD SURFACE WAS DRY,WITHOUT ANY POTHOLES,BUMPS,ETC. I TOOK THE CAR TO THE TOYOTA SERVICE CENTER. AFTER CHECKING MY CAR THEY INFORMED ME THAT THE COMPUTER DID NOT DETECT ANY MALFUNCTIONS, THE TEST DRIVE WAS ALSO UNEVENTFUL,SO THAT NOTHING COULD BE DONE TO RESOLVE THE PROBLEM. THIS CAR'S BRAKING IS OBVIOUSLY UNPREDICTABLE AND IT IS ,WITHOUT A DOUBT, NOT SAFE TO DRIVE. *TR

CAR ABS LIGHT COMES ON, AND AT THE SAME TIME VEHICLE LOSES BRAKE ASSIST OR BRAKE ASSIST BECOMES UNEVEN. CAR HAS HAD THREE BRAKE LIGHT FAILURES - 1 WITH PREVIOUS OWNER AND 2 WITH CURRENT OWNER. FIRST FAILURE WAS REPAIRED BY RESETTING THE COMPUTER, WE THINK. WITH CURRENT OWNER, DEALER HAS REPLACED THE ANTILOCK SENSOR TWO TIMES, AND WITH THE SECOND SENSOR REPLACEMENT TOYOTA NOW HAS PRONOUNCED THE VEHICLE AS SAFE. SINCE THE BRAKES FAILED AFTER THE FIRST SENSOR REPLACEMENT, WE HAVE LITTLE CONFIDENCE THAT THE PROBLEM WAS SOLVED WITH THE SECOND SENSOR REPLACEMENT. WE ARE CONCERNED ABOUT VEHICLE SAFETY, ESPECIALLY SINCE THE CAR IS FREQUENTLY DRIVEN IN HEAVY WASHINGTON BELTWAY TRAFFIC. TYPICALLY CAR RUNS FOR SOME TIME AND THEN FAILS, SO WE DO NOT KNOW IF AND WHEN IT WILL HAPPEN AGAIN. DEALER AND TOYOTA HAVE BEEN UNSUPPORTIVE TO OUR CONCERNS. *TR

I FIRST REPORTED THIS TO TOYOTA PRIOR TO THE INITIAL 2010 RECALL, THE CAR WAS LESS THAN 1 MONTH OLD AND I HAVE REPORTED IT ON NUMEROUS OCCASIONS VIA THE TOYOTA WEBSITE. ON THE FEW OCCASIONS I LENT THE CAR TO FRIENDS THEY HAVE HAD THE SAME EXPERIENCE. DESCRIPTION: WHEN TRAVELING AT RELATIVELY SLOW SPEEDS AND AN UNEXPECTED BUMP COMES UP AND THE BRAKES ARE ENGAGED EARLY, ONCE GOING OVER THE BUMP THE CAR LOSSES BRAKE POWER FOR A FEW SECONDS AND JOLTS FORWARD. IT IS VERY DISCONCERTING B/C IN THOSE SPLIT SECONDS IF ONE IS NOT PREPARED THE CAR HURLS FORWARD AND COULD IF ALL ODDS ARE AGAINST ME, THE CAR COULD KILL SOMEONE IF THEY ARE WALKING IN FRONT OF THE CAR. I REPORTED IT TO MY DEALER, MY DEALER'S INSPECTOR WENT OUT ON TEST DRIVE WITH ME, WE WERE ABLE TO RECREATE THE INCIDENT WHEN HE WAS DRIVING AS THERE ARE A FEW SPOTS IN MY NEIGHBORHOOD THAT IT HAPPENS EVERY TIME. HE PUT THE COMPUTER ON THE CAR BUT IT DID NOT READ THERE WAS A PROBLEM. HE CALLED THE NATIONAL TECHNICAL OFFICE, WHO EVENTUALLY CAME OUT, I LEFT THE CAR AT THE DEALERSHIP. THEY RECREATED THE PROBLEM AND ACCORDING TO THE LOCAL TECHNICIAN THEY PUT A CAMERA IN THE WHEEL TO FILM THE SITUATION. I WAS LATER TOLD BY MY LOCAL TECHNICIAN THAT IT WAS DETERMINED THAT THERE WAS NOT A PROBLEM WITH THE CAR AND THAT THE SITUATION IS NORMAL WHERE THE TIRE CATCHES AN UNEVEN SURFACE AND GOES INTO OVERDRIVE. I HAVE HAD DREAMS THAT I WOULD KILL SOMEONE IN THIS CAR. NOONE IS ALLOWED TO USE THIS CAR FOR THE SAME REASON. I FEAR FOR MY LIFE AND THE LIFE OF ANYONE WALKING IN FRONT OF ME ON A STREET I DO NOT KNOW. IT HAPPENS ALMOST EVERY 2 WEEKS. IT IS SCARY! PLEASE HELP! THIS IS THE FIRST NEW CAR I BOUGHT IN 25 YEARS AND I AM UNABLE TO GET RID OF IT B/C I HAD TO PAY SO MUCH FOR IT. WHEN I INQUIRED WHAT MY OPTIONS WERE, TOYOTA SAID NONE, THAT THERE IS NO PROBLEM WITH THE CAR. *TR

I PURCHASED MY 2010 PRIUS IN AUGUST 2010. FOR THE PAST YEAR, I HAVE HAD PROBLEMS WITH THE BRAKE SYSTEM WHEN ATTEMPTING TO BRAKE AT LOW SPEEDS. WHEN BRAKING AT LOW SPEEDS, SUCH AS STOPPING AT A RED LIGHT OR STOP SIGN, IF THE CAR HITS A BUMP OR A POTHOLE, IT STOPS BRAKING AND INSTEAD ACCELERATES FORWARD A BIT. IT IS EXTREMELY FRIGHTENING AND I FIND IT EXCEPTIONALLY DANGEROUS. I HAVE COME EXTREMELY CLOSE TO HITTING THE VEHICLES IN FRONT OF ME ON SEVERAL OCCASIONS. I NOW HAVE TO TRY TO CONSCIENTIOUSLY ADJUST AND DRIVE VERY, VERY SLOWLY WHEN BRAKING ON UNEVEN ROAD SURFACES SINCE I HAVE COME TO ANTICIPATE THIS PROBLEM. HOWEVER, MANY TIMES THERE IS NO WAY TO AVOID THE CAR'S SURGE OF POWER. I BELIEVE THIS IS A HIGHLY DANGEROUS SITUATION WITH MY VEHICLE. A SIMPLE INTERNET SEARCH WILL DEMONSTRATE THAT THIS PROBLEM EXISTS AND WAS NOT RESOLVED WITH THE RECALL IN MARCH 2010. I PURCHASED MY PRIUS, NEW, FIVE MONTHS AFTER THE PROBLEM WAS ALLEGEDLY FIXED AND I HAVE HAD THIS PROBLEM SINCE DAY ONE. THE BRAKES HAVE BEEN EXAMINED ON MY VEHICLE BY A TOYOTA DEALER AND THEY APPEAR TO BE FINE. I HIGHLY BELIEVE THAT A RECALL IS APPROPRIATE TO FIX THIS DANGEROUS BRAKING ISSUE. *TR

DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
DP19004 · Brake Actuator Valve Wear
Opened Sep 30, 2019 · Closed Jan 21, 2021
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
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.
PE10006 · Braking Performance, Hybrid Vehicle

The subject vehicles are the first model year of a new design generation of the Prius model line.The vehicles are powered by a hybrid drive system that uses both a regenerative braking system, which converts vehicle momentum into electrical energy to be stored in onboard batteries, and a hydraulic brake system more typical of the brake system used on non-hybrid vehicles.As is the case for other similarly designed hybrid vehicles the interaction and management of the two braking systems during ABS braking is complex and requires a sophisticated control system.In a February 9, 2010 Defect Information Report, Toyota advised the agency of its plans to conduct a safety recall to address inconsistent brake feel and increased stopping distances that may occur during braking events requiring ABS operation, such as would occur when braking on rough or low friction road surfaces.Toyota will reprogram the ABS control unit with improved software that addresses this condition.Based on Toyota's action the investigation is closed. ODI will continue to monitor the subject vehicles' performance and will take further action as future circumstances dictate.
