2010 Toyota Prius complaints

LOW SPEED BRAKE FAILURE ON 2010 TOYOTA PRIUS. THIS DESCRIBES JUST ONE OF MULTIPLE TIMES I HAVE HAD WHAT SEEMS LIKE A SHORT, BUT TOTAL LOSS OF BRAKES ON THIS VEHICLE. EACH TIME, I WAS EASY TO MEDIUM BRAKING AND HIT A BUMP OR WAS ON ROUGH SURFACE. THE BRAKES JUST APPEAR TO FAIL. NATURAL REACTION IS TO PRESS HARDER ON BRAKE PEDAL. USUALLY BY THIS REACTION TIME THE BRAKES ARE BACK AND YOU STOP ABRUPTLY OR SKID TO A STOP. IT HAS SOMETHING TO DO WITH ROUGH ROADS OR BUMPS THAT HAPPEN AT A GIVEN POINT DURING BRAKING. VERY SCARY SITUATION. THIS HAS HAPPENED ON BOTH DRY PAVEMENT AND SNOW PACKED ROADS. AGAIN, THE COMMON FACTOR IS THE "BUMP" DURING BRAKING. EACH TIME I WAS THE ONLY PERSON IN THE VEHICLE AND THE VEHICLE HAD NO ADDITIONAL REAR WEIGHT. SPEED WAS UNDER 25-30 MPH. *TR

WE HAD PICKED UP OUR BRAND NEW TOYOTA PRIUS 2010 ON SEP 24TH 2009. A WEEK LATER, ON OCT 1, I WAS DRIVING IN TO MY BROTHER IN LAW'S DRIVEWAY (MAYBE AT 5MPH) WHEN I FELT THAT THE BRAKE PEDAL DID NOT ENGAGE. I CRASHED INTO THEIR GARAGE DOOR. SINCE, THIS WAS A METAL DOOR, WE THOUGHT WE COULD DENT IT BACK IN AND REPAINT IT. THEREFORE, IT WAS NOT REPORTED TO INSURANCE. SINCE THEN, I HAVE FELT A COUPLE MORE TIMES THAT THE BRAKE DID NOT ENGAGE EITHER QUICKLY ENOUGH OR HARD ENOUGH. I AM NOT A RASH DRIVER. I HAVE NOT HAD A TRAFFIC VIOLATION IN ABOUT 8 YEARS OR SO. I AM VERY WORRIED OUT THIS. WE HAVE 2 CHILDREN THAT ARE IN THE CAR A LOT WITH ME. PLEASE ADVISE. *TR

I LOSE ALL BRAKING FOR A FEW SECONDS ON MY 2010 TOYOTA PRIUS WHILE GOING OVER ROUGH ROADS AT SLOW SPEED. I HAVE NOT TRIED THIS AT HIGHWAY SPEEDS. I WANTED TO WAIT TO LEARN MORE OF THE PROBLEM FROM MY DEALER. SO WHEN I WAS AT MY TOYOTA DEALERSHIP ON 28 JAN 10,FOR MY CAR'S FIRST SCHEDULED MAINTENANCE, THE ASSISTANT SERVICE MANAGER STATED THAT THE PROBLEM IS PREVALENT ON MOST TOYOTA VEHICLES INCLUDING THE TRUCK HE OWNED. BUT THAT'S NOT WHAT REPORTS HEARD TODAY, 3 FEB 10. *TR

MY 2010 PRUIS TENDS TO LURCH FORWARD WHEN BRAKING. THIS MAINLY SEEMS TO OCCUR WHEN THE SURFACE CHANGES WHILE BRAKING, LIKE DRIVING OVER A MANHOLE COVER, POTHOLE OR SLIPPERY SURFACE. I HAVE EXPERIENCED THIS EVERY SINCE I BOUGHT THE CAR IN JUNE 2009. I REPORTED IT TO THE DEALER AT MY FIRST CHECK-UP, AND WAS TOLD THAT IT WAS A FUNCTION OF THE UNIQUE BRAKING SYSTEM ON THE PRIUS, AND THAT THEY HADN'T HEARD THE COMPLAINT BEFORE (TOO NEW IN THE MODEL YEAR). NO RECORD WAS MADE OF MY COMPLAINT. I HAVE LIVED WITH IT EVER SINCE, AND IT HAPPENS AT LEAST TWICE A WEEK; JUST HAPPENED AGAIN YESTERDAY. AT ONE INTERSECTION ON MY COMMUTE I HIT THE SAME SURFACE EVERY TIME AND IT LURCHES ALMOST EVERY TIME. IT FEELS ALMOST AS IF I HAVE LIFTED MY FOOT OFF THE BRAKE PEDAL AND IT LURCHES FORWARD, ALTHOUGH I CAN'T SAY IF IT FEELS LIKE IT IS ACCELERATING OR IF IT IS JUST THE INERTIA OF THE CAR THAT CAUSES IT TO LURCH FORWARD. IT HAS NOT CAUSED AN ACCIDENT YET, BUT SINCE THE CAR LURCHES A FEW FEET FORWARD, I KNOW THAT I WOULD HIT ANY CAR TOO CLOSE IN FRONT OF ME. I ALSO WORRY THAT IN SNOW OR ICE IT WOULD CAUSE A SKID TO OCCUR OR SEND ME INTO A DIFFERENT LANE. I WAS NOT AT ALL SURPRISED TO HEAR ABOUT THIS ON THE NEWS THIS MORNING, AND REGRET THAT I DID NOT KNOW ABOUT THIS COMPLAINT FORM TO FILE OR I WOULD HAVE BACK IN JULY. I CAN'T STATE AN INCIDENT DATE SINCE IT IS ONGOING. *TR

WHILE DEPRESSING THE BRAKE PEDAL IN THE 2010 PRIUS, THE VEHICLE WILL LOSE ALL BRAKING POWER IF YOU HIT A BUMP OR POT HOLE IN THE ROAD. I HAVE EXPERIENCED THIS SEVERAL TIMES WHILE DEPRESSING THE BRAKE, APPROACHING AN INTERSECTION. WHEN I DRIVE OVER THE BUMP IN THE ROAD (AND CONTINUE PRESSING THE BRAKE) THE VEHICLE SURGES FORWARD AS IF MY FOOT HAD RELEASED THE BRAKE. THE ONLY WAY TO STOP THE VEHICLE IS TO IMMEDIATELY RE-ENGAGE THE BRAKE FULLY. I HAVE CAME VERY CLOSE TO REAR ENDING THE VEHICLE IN FRONT OF ME DUE TO THIS DESIGN / MECHANICAL FLAW. I CAN RECREATE THIS SCENARIO EACH TIME I CROSS A CERTAIN PORTION OF THE ROAD I COMMUTE ON. *TR

WHEN BRAKING NUMEROUS TIMES, MY 2010 TOYOTA PRIUS HAS STOPPED BRAKING AND GIVES THE FEELING THAT IT IS LURCHING FORWARD. MY MOST RECENT INCIDENT OCCURRED WHEN I WAS DRIVING OVER A MAN HOLE AT ABOUT 30-35 MPH. THESE INCIDENTS TYPICALLY OCCUR WHEN BRAKING OVER NON-SMOOTH ROAD SURFACES, SUCH AS POTHOLES. I HAVE OWNED THE CAR SINCE JUNE 2009. *TR

MY 2010 TOYOTA PRIUS SEEMS TO HAVE BRIEF PERIODS OF ACCELERATION WHEN I TAKE MY FOOT OFF THE ACCELERATOR AND AM JUST PUTTING IT ON THE BRAKE. I HAVE TO BRAKE HARD TO KEEP IT FROM LURCHING FORWARD. *TR

I AM DRIVING A 2010 TOYOTA PRIUS SINCE AUGUST 2009. UNDER CERTAIN CONDITIONS THE BRAKES SEEM TO MALFUNCTION. I CAN REPLICATE THIS ISSUE ON A CERTAIN ROAD WHEN I AM COMING DOWN A SLOPE APPROACHING A TRAFFIC LIGHT AND THE VEHICLE (DRIVER SIDE FRONT TIRE) HITS A POTHOLE AS I AM BRAKING. THE VEHICLE CONTINUES TO GO FORWARD MOMENTARILY INSTEAD OF THE BRAKES WORKING AS THEY SHOULD. THE DATE MENTIONED BELOW IS THE MOST RECENT TIME I HAVE EXPERIENCED THIS ISSUE. ALL TOGETHER THIS HAS OCCURRED APPROX. 10 TIMES SINF AUGUST. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT NOTICED THAT THERE WERE OCCASIONS WHEN HE LOST BRAKING POWER AND SLIGHT ACCELERATION WHEN HE DROVE OVER A POTHOLE OR BUMP IN THE ROAD. HE STATED THAT THE ISSUE OCCURRED WHEN DRIVING AT LOW SPEEDS IN NORMAL ROAD CONDITIONS. THE CONTACT WAS ABLE TO REGAIN CONTROL AND RESUME NORMAL OPERATION ALMOST IMMEDIATELY AFTER THE FAILURE. HE EXPERIENCED THE ISSUE AT LEAST 12 DIFFERENT TIMES. HE HAD NEITHER TAKEN THE VEHICLE TO THE DEALERSHIP NOR SPOKEN WITH THE MANUFACTURER AT THE TIME OF THE COMPLAINT. THE VEHICLE HAD NOT BEEN REPAIRED TO-DATE. THE CURRENT MILEAGE WAS APPROXIMATELY 3,000. THE FAILURE MILEAGE WAS APPROXIMATELY 150.

I HAVE A 2010 PRIUS. I HAVE NOTICED A PROBLEM WITH THE BRAKING IN CERTAIN CONDITIONS AS DESCRIBED: WHEN THE PRIUS HITS A PATCH OF UNEVEN PAVEMENT OR IS TAKING A SHARP TURN WHILE LIGHTLY BRAKING, THE PRIUS' BRAKE ECU INTERPRETS THAT AS A SITUATION WHERE THE COMPUTER NEEDS TO STEP IN AND KEEP THE WHEELS FROM LOCKING UP. THE BRAKES DO END UP WORKING BUT IT IS AN UNSETTLING AND DEFINITELY A POTENTIAL DANGEROUS SITUATION AS THERE IS A SURGE PRIOR TO THE BREAKS ACTUALLY WORKING. THE SURGE ONLY LASTS A SECOND OR SO BUT IT DOES FEEL LIKE THE CAR IS ACTUALLY ACCELERATING AND NOT BRAKING FOR THAT BRIEF MOMENT. *TR

WHEN ATTEMPTING TO BRAKE WHILE COMING TO A TRAFFIC LIGHT ON A SLIGHTLY ICY ROAD, THE CAR ACCELERATED. IT WAS NOT THE FUNCTION OF ANTILOCK BRAKES, BUT RATHER A SURGE THAT WAS TOTALLY UNEXPECTED AND SOMEWHAT FRIGHTENING. LUCKILY THERE WAS NO CAR IMMEDIATELY IN FRONT OF ME, OR I WOULD HAVE SURELY REAR ENDED IT. I REPORTED THIS TO TOYOTA AND THERE IS A CASE NUMBER - 1001142944. GIVEN TOYOTA'S SLOWNESS TO REACT TO THE GAS PEDAL ISSUE, I WANT TO NOTIFY NHTSA. *TR

MY 2010 PRIUS LURCHES OVER BUMPS. THE DEALERSHIP SAID I WAS THE ONLY ONE WITH THIS PROBLEM AND FOUND NOTHING WRONG ON TWO VISITS. I READ THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM, SO I WANT TO ISSUE A COMPLAINT AND ASK WHAT I SHOULD DO NOW. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRUIS. THE CONTACT STATED THAT WHILE DRIVING IN REVERSE WITH HER FOOT ON THE BRAKE PETAL, THE VEHICLE ACCELERATED ON ITS OWN. THE CONTACT THEN APPLIED THE BRAKES AND IT STOPPED. SHE THEN TURNED OFF THE VEHICLE AND IT DROVE NORMALLY. THE ISSUE HAS OCCURRED A TOTAL OF 5 TIMES. THE VEHICLE HAD NOT BEEN DIAGNOSED AT THE TIME OF THE COMPLIANT.THE DEALER WILL BE CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN AND CURRENT MILEAGE WAS 2500.

MY 2010 PRIUS BRAKES BRIEFLY STOP WORKING WHEN I'M BRAKING WHILE DRIVING OVER A BUMP OR POTHOLE. I HAVE NOT BEEN IN AN ACCIDENT HOWEVER THIS CAN LEAD TO AN ACCIDENT IN THE FUTURE. THIS HAPPENS PERIODICALLY AND CAN BE RECREATED. *TR

MY 2010 TOYOTA PRIUS SUDDENLY SURGED FORWARD FOR A FEW FEET AFTER GOING OVER A LITTLE BUMP IN THE ROAD (LIKE A MANHOLE COVER). THIS HAPPENED A COUPLE OF TIMES. NO INJURIES OR ACCIDENTS. I BROUGHT THIS TO THE ATTENTION OF MY DEALER WHEN I BROUGHT IT IN TO CHANGE THE OIL @ 5000 MILES. THEY SAID THEY COULD NOT REPLICATE OR DETECT THE PROBLEM. I HAVE NOT HAD ANY SUCH INCIDENTS IN THE PAST 2 MONTHS. *TR

MY 2010 TOYOTA PRIUS EXPERIENCES ACCELERATION WHENEVER I GO OVER A POTHOLE AND ATTEMPT TO BRAKE THE CAR. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE IN AUGUST 2009. I AM REPORTING IT NOW BECAUSE I NOW KNOW THAT OTHER OWNERS HAVE REPORTED THE SAME PROBLEM AND IT IS NOT A RESULT OF MY INABILITY TO GET USED TO DRIVING A HYBRID. THIS IS A SERIOUS SAFETY ISSUE AS I'M ALARMED THAT I MAY BE UNABLE TO BRAKE SUDDENLY IF THIS HAPPENS IN A SITUATION THAT WARRANTS ME TO QUICKLY BRAKE. *TR

2010 PRIUS I HAVE DEFINITELY BEEN GETTING THE LURCHING OVER BUMPS THAT I'VE HEARD OTHER 2010 PRIUS OWNERS COMPLAIN ABOUT. HAPPENS A LOT WHEN I DRIVE OVER A MANHOLE COVER, THE CAR SEEMS TO SPEED UP FOR A BRIEF MOMENT. I HAVEN'T HAD AN ACCIDENT FROM THIS YET, BUT WANTED TO REGISTER MY COMPLAINT WITH WHOMEVER ELSE IS HAVING THE SAME PROBLEM. *TR

WHEN BRAKING OVER A SMOOTH SURFACE SUCH AS A MANHOLE COVER, THE VEHICLE TENDS TO LURCH FORWARD. *TR

MY 2010 TOYOTA PRIUS SEEMS TO LOOSE BRAKING ON OR OVER BUMPS. IT SEEMS TO NOT WANT TO STOP FOR A FEW SECONDS AFTER HITTING A BUMP IN THE ROAD. I HAVE TO REMOVE MY FOOT FROM THE BRAKES AND RE APPLY INORDER TO REGAIN BREAKING. THIS HAPPENS ALMOST EVERY TIME WHEN SIMULTANEOUSLY APPLYING THE BRAKES AND GOING OVER A BUMP/POTHOLE IN THE ROAD. *TR

WHEN BRAKING, THE BRAKES SEEM TO LOOSE PARTIAL GRIP ON AND OFF. ALSO WHEN BRAKING OVER A POTHOLE OR UNEVEN ROAD THE CAR SEEMS TO ACCELERATE SUDDENLY AND THERE IS A FEEL OF LOSS OF CONTROL. THESE ARE BOTH VERY SCARY. *TR

2010 PRIUS BRAKES DOES NOT WORK IF THE VEHICLE GOES OVER A BUMP OR A POT HOLE WHILE BRAKES BEING APPLIED..IT HAS HAPPENED SEVERAL TIMES...EVEN COMPLAINED TO THE DEALER ONCE...DEALER SAYS THERE ARE NO TECHNICAL BULITON OR TECHNICAL FIX ON THE ISSUE. *TR

MY 2010 PRIUS HAS BRAKES RELEASING WHILE MY FOOT IS ON THE BRAKE PEDAL. IN REVERSE THE BRAKES FREQUENTLY "STICK" ON. IN THIS MOST RECENT INCIDENT I WAS CHANGING LANES LOOKING TO MAKE A FUTURE LEFT TURN AND I WAS IN THE RIGHT LANE OF A 4 LANE ROAD, I WAS SLOWING DOWN TO CHANGE LANES AND DID NOT SEE A CAR IN MY "BLIND SPOT" WHERE MY MIRRORS DID NOT SHOW THE CAR. ONCE I SIDE SWIPED THE ACURA MDX, I MADE EMERGENCY MANEUVERS TO GET BACK TO THE RIGHT LANE, WHICH INCLUDED SWERVING RIGHT AND HITTING THE BRAKES AFTER THE CAR STARTED MOVING RIGHT. AT THAT POINT MY VEHICLE SEEMED TO MOVE ON IT'S OWN IRREGARDLESS OF MY PEDAL AND STEERING ACTIONS (I WAS IN PANIC MODE SINCE I HAVEN'T HAD AN ACCIDENT IN DECADES - EXCEPT A PARKING LOT "BUMP"). I WROTE OFF THE FACT THAT I WAS UNABLE TO DEFENSIVELY DRIVE AS I HAVE RELIED ON FOR ALL THESE YEARS SINCE I COULDN'T PULL OUT OF THE ACCIDENT. NOW HOWEVER, AFTER HEARING OF THE SIMILAR ISSUES ON 2010 PRIUS I AM WONDERING WHETHER THE VEHICLE PLAYED A PART IN THE ACCIDENT THAT I COULD NOT COMPENSATE FOR? *TR

I BOUGHT A 2010 TOYOTA PRIUS II NOVEMBER 2009. WITHIN 1 MONTH PERIOD, I HAD EXPERIENCE TWO SEPARATE BRAKE PROBLEM. ONCE WAS PASSING A RAILWAY TRACK AND THE OTHER TIME WAS MAKING A RIGHT TURN. BOTH TIMES I STEPPED THE BRAKE TO REDUCE SPEED AND FAILED. THAT MEANS THE BRAKE DID NOT REDUCE THE SPEED OF THE VEHICLE. FORTUNATELY, NO CAR WAS IN FRONT ME AND NO ACCIDENT HAPPENED. I THEN REPORTED TO MY DEALER AND SENT MY CAR BACK TO CHECK. THE DEALER TOLD ME THEY FAILED TO REPLICATE THE SITUATION AND EVERYTHING WAS NORMAL. NOTHING WAS DONE. THEY THEN TALKED TO TOYOTA CUSTOMER SERVICE LINE AND TOYOTA SAID IT IS NORMAL TO FEEL THE BRAKE DID NOT ENGAGE WHEN CROSSING A BUMP. I WAS REALLY DISAPPOINTED. *TR

WHEN I BRAKE MY 2010 PRIUS AND HIT A BUMP IT LURCHES FORWARD, CAUSING MOMENTARY LOSS OF CONTROL. *TR

REGENERATIVE BRAKING DISENGAGES FOR A SECOND OR TWO BEFORE MECHANICAL BRAKING TAKES OVER CAUSING CAR TO LURCH FORWARD/ACCELERATE WHEN BRAKING ON UNEVEN ROAD SURFACES. THIS EFFECT WAS NOTICED TWICE AT SPEEDS LESS THAN 15 MPH WHEN FRONT TIRES HIT RUTS IN ROAD ATTEMPTING TO BRAKE AT STOP LIGHTS OR WHEN GOING AROUND A CORNER. I TRY TO DRIVE CLOSE TO THE RIGHT CURB ON THE EVEN ROAD SURFACE TO AVOID BREAKING WHEN POT HOLES/RUTS ARE PRESENT IN MY LANE WHERE OTHER CARS TYPICALLY DRIVE. *TR

2010 PRIUS. CAR LURCHES EVERYDAY WHEN BRAKING AT STOP SIGNS. CAR DRIFTS FORWARD AND DOES NOT IMMEDIATELY RESPOND TO BRAKE PEDAL BEING PUSHED DOWN. OFTEN HAPPENS IN THE MIDDLE OF THE STOP. BRAKES WILL START WORKING BUT THEN "SLIP" IN THE MIDDLE AT VERY LOW SPEEDS. DOUBT THE ANTI-LOCK BRAKE SYSTEM COULD BE THE PROBLEM AS SPEED ARE VERY LOW. HAS BEEN OCCURRING SINCE THE CAR WAS PURCHASE IN THE SUMMER OF 2009. *TR

SUDDEN ACCELERATION LOSS OF BRAKING WHILE DRIVING OVER BUMPY ROAD AT SLOW SPEED. THIS HAS HAPPENED SEVERAL TIMES. NO ACCIDENT RESULTED. HAVING READ REPORTS OF THIS IN THE NEWS, I WANTED TO REPORT IT AS WELL. *TR

I HAVE CONTACTED MY AUTO MANUFACTURER ABOUT A STEERING PROBLEM. THE CAR WILL NOT DRIVE IN STRAIGHT LINE, IT IS ETHER GOING LEFT OR RIGHT. THEY HAVE NOT RESPONDED TO MY COMPLAINT. I HAVE TO BE VERY CAREFUL DRIVING THIS CAR BECAUSE IT WILL WONDER OFF OF THE ROAD. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED HER VEHICLE SURGES WHEN SHE GOES OVER A POTHOLE AND HIT HER BRAKES. THIS HAS BEEN HAPPENING SINCE SHE PURCHASE HER VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER AND THE TECHNICIAN TEST DROVE THE VEHICLE WITH HER BUT THE FAILURE DID NOT OCCUR AGAIN. THE FAILURE MILEAGE WAS 4,000.

FROM THE FIRST DAYS WITH THIS VEHICLE WE HAVE HAD AN INTERMITTENT ISSUE WITH THE BRAKES. SO FAR, THIS ISSUE ONLY OCCURS AT VERY SLOW SPEEDS, SUCH AS WHEN BACKING OUT OF THE GARAGE OR WHEN BACKING OUT OF PARKING SPACES. ON OCCASION, WE HAVE EXPERIENCED THIS PROBLEM IN THE FORWARD DIRECTION WHEN STOPPING IN THE SLOW CONDITIONS OF A PARKING LOT. FOLLOWING IS A DESCRIPTION OF THE BRAKING ACTION: 1. I START THE CAR (POWER BUTTON WITH FOOT ON THE BRAKE). 2. I PLACE THE SHIFT LEVER IN REVERSE OR DRIVE WITH FOOT ON THE BRAKE. 3. I RELEASE THE BRAKE PEDAL. 4. THE CAR EASES BACKWARD (OR FORWARD, AS THE CASE MAY BE). 5. I APPLY THE BRAKE , EITHER TO SHIFT INTO DRIVE OR TO CHECK FOR TRAFFIC BEFORE CONTINUING. 6. SEVERAL TIMES PER WEEK THE BRAKES LOCK THE INSTANT MY FOOT TOUCHES THE BRAKE PEDAL. 7. WHEN THIS PROBLEM OCCURS, THE LOCKING ACTION WILL REPEAT EACH TIME I RELEASE THE BRAKE, EASE BACKWARD OR FORWARD, AND BRAKE AGAIN. 8. THE BRAKE LOCKING IS SO INSTANTANEOUS THAT PASSENGERS' HEADS JERK AND THEY LOOK SURPRISED. 9. THE BRAKING ACTION IS MORE LIKE THAT OF FLIPPING AN ELECTRICAL SWITCH THAN OF PRESSING A BRAKE PEDAL. 10. FROM THE BEGINNING, I HAVE TRIED TO DETERMINE IF A CERTAIN SEQUENCE OF ACTIONS TRIGGERS THE LOCKING. I CANNOT COME UP WITH ANYTHING. SO FAR, THE ONLY CONSTANT IS THAT THIS LOCKING HAPPENS WITH THE FIRST STOPS AFTER STARTING THE CAR. I HAVE NOT EXPERIENCED IT WITH SUBSEQUENT STOPS. HOWEVER, HEAVEN HELP US IF THIS WERE TO OCCUR AT HIGHER SPEEDS! AT THE 5000 MILE SERVIC

DRIVING A 2010 PRIUS WITH A HALF INCH OF FRESH SNOW ON A RESIDENTIAL STREET AT 20 DEGREES. DRIVING AT 12 MPH, SLOWING TO A STOP AT A STOP SIGN. TWICE THE BRAKES STOPPED WORKING, CAUSING ME TO COME TO A STOP BEYOND THE PEDESTRIAN CROSSWALK. FORTUNATELY, NO PEDESTRIANS WERE THERE. IT FELT AS IF ABS HAD ENGAGED, CAUSING ME TO LOSE CONTROL OF BRAKING. EVEN IF THIS IS A DESIGN ELEMENT, IT CAUSED ME TO NOT BE ABLE TO STOP IN TIME. I WAS GOING 7 MPH WHEN THIS HAPPENED AND WOULD HAVE EASILY STOPPED THE CAR IN TIME IF THIS HAD NOT HAPPENED. AFTER THIS INCIDENT I HAD TO APPROACH INTERSECTIONS AT 3-5 MPH, AFRAID THAT MY SLOW SPEED WOULD CAUSE SOMEBODY BEHIND ME TO REAR END ME. *TR

I DRIVE A 2010 TOYOTA PRIUS AND WOULD LIKE TO REPORT THAT WHEN BRAKING, IF I HIT A POT HOLE OR BUMP, THE CAR LUNGES FORWARD OR ACCELERATES FOR A SPLIT SECOND. I HAVE HAD MY CAR FOR JUST UNDER 60 DAYS BUT HAVE HAD THIS EXPERIENCE AT LEAST A DOZEN TIMES. IT HAS NOT CAUSED AN ACCIDENT, BUT LEAVES ME FEELING AS IF THERE ARE MOMENTS THAT I DO NOT HAVE CONTROL OF MY CAR. IT'S LIKE IT HAS A MIND OF IT'S OWN! *TR

VEHICLE SURGES FORWARD WHEN BRAKING OVER ROAD SURFACE THAT IS NOT SMOOTH. SYMPTOM MAKES SAFELY JUDGING STOPPING DISTANCE VERY DIFFICULT, AND IN OUR OPINION, INCREASES LIKELIHOOD OF AN ACCIDENT. TOYOTA DEALER CLAIMED THEY COULD NOT REPLICATE ISSUE AND THAT VEHICLE'S COMPUTER DID NOT REPORT/RECORD ANY PROBLEMS. WE CAN REPLICATE ISSUE OVER SAME BUMP EVERYDAY. *TR

I PURCHASED A 2010 TOYOTA PRIUS V IN NOVEMBER 2009. SHORTLY AFTERWARDS MY WIFE EXPERIENCED THE PROBLEM WITH THE BRAKES. SHE WENT TO APPLY THE BRAKES BUT THE CAR JUST WOULD NOT SLOW DOWN. SHE PRACTICALLY HAD TO STAND TO APPLY ENOUGH PRESSURE TO BRING THE CAR TO A STOP. WE WENT BACK TO THE DEALER TWICE, BUT COULD NOT FIND ANYTHING WRONG. *TR

WHEN BRAKING, MY TOYOTA PRIUS UNEXPECTEDLY JOLTS FORWARD IF I HIT A BUMP IN THE ROAD. THIS HAPPENS CONSISTENTLY NEARLY EVERY DAY I DRIVE IT. *TR

TOYOTA PRIUS 2010 SUDDENLY STOPS AND STALLS AT LOW SPEEDS. AFTER THIS, IT WOULD NOT START FOR 20 MINUTES, DESPITE REPEATEDLY TURNING THE ENGINE ON AND OFF. *TR

2010 TOYOTA PRIUS SEEMS TO ACCELERATE WHEN I APPLY BRAKES TO SLOW DOWN AND CAR GOES INTO SHALLOW POTHOLE. THIS EVENT IS REPEATABLE AND HAPPENS EVERY TIME I SLOW DOWN AT A PARTICULAR STOP SIGN WITH A POTHOLE IN FRONT OF IT. FORTUNATELY THERE HAS NEVER BEEN A CAR IN FRONT OF ME AND I NOW KNOW TO AVOID THIS SPOT. CAR BEHAVES NORMALLY ONCE IT HAS CLEARED THE POTHOLE. THIS OCCURS AT SLOW SPEEDS ( 20MPH DOWN TO 0 ) HAS NOT HAPPENED ANYWHERE ELSE, BUT HAPPENS EVERYTIME AT THIS LOCATION. *TR

I BOUGHT MY NEW 2010 PRIUS JUNE 6TH 2009. SINCE ABOUT OCT 2009, I HAVE NOTICED WHEN I AM BRAKING AND GO OVER A POTHOLE IN THE ROAD, THE CAR SEEMS TO SPEED UP. THERE IS A POTHOLE BY MY HOUSE SO I CAN TEST THIS FREQUENTLY. IT HAPPENS WHEN I GO ABOUT 30 MPS (AS I'M SLOWING DOWN DUE TO THE STOP LIGHT ON THE CORNER). I TOOK MY 2010 PRIUS INTO THE DEALERSHIP ON DEC 28TH AND THEY WERE VERY UNHELPFUL AND RUDE. THEY TOLD ME TO REMOVE MY FLOOR MATS EVEN THOUGH WHAT MY ISSUE WAS HAD NOTHING TO DO WITH FLOOR MATS OR THE GAS PEDAL. WHAT CAN I DO TO HELP ENCOURAGE THEM TO FIX THIS ISSUE AS I FIND IT UNSAFE TO DRIVE MY CAR?? I HAVE ALMOST REAR ENDED THE CAR IN FRONT OF ME TWICE. IT'S VERY CONCERNING. *TR

TL* THE CONTACT HAS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE VEHICLE FEELS AS IF THE BRAKES RELEASE IF HE HITS A BUMP WHILE PRESSING THE BRAKES. THE CONTACT STATED THAT IT FELT LIKE THE VEHICLE SURGED FORWARD.THE CONTACT STATED THAT IT ONLY HAPPENS WHEN THE VEHICLE HITS A BUMP OR POTHOLE. THE FAILURE MILEAGE WAS 100. THE CURRENT MILEAGE WAS 5000.

THE BRAKES SEEM TO RELEASE IF THEY ARE BEING APPLIED WHILE DRIVING OVER A ROUGH SURFACE - SPEED BUMP, POTHOLES, ETC. THIS HAS OCCURRED ABOUT 10-15 TIMES SINCE BUYING THE VEHICLE IN AUGUST 2009. *TR

WHEN I DRIVE OVER A BUMPY ROAD AND APPLY THE BRAKES, MY CAR DOES NOT STOP. *TR

THE CAR HAS HYPER-SENSITIVE BRAKES WHENEVER I AM BACKING UP FROM A PARKED SPOT (E.G. BACKING UP FROM A PARKING SPACE AT A STORE.) WHEN BACKING OUT OF A SPACE (USING JUST IDLE SPEED AND TAPPING LIGHTLY ON THE BRAKES TO CONTROL THE SPEED) TAPPING LIGHTLY RESULTS IN THE CAR BRAKES FORCEFULLY ENGAGING AND SLAMMING THE CAR TO A STOP. THIS HAPPENS ONLY AFTER THE CAR HAS BEEN WARMED UP; PARKED (LIKE GOING TO THE STORE TO SHOP) AND THEN YOU RE-ENTER IT TO LEAVE. THE HYPER SENSITIVE BREAKS CONTINUE FOR A SHORT PERIOD OF TIME WHILE I AM POSITIONING THE CAR TO GET OUT OF A PARKING SPACE AND ONTO THE ROAD. AFTER THE FIRST OCCURRENCE OF THE FORCEFUL BRAKING, PUTTING THE CAR IN PARK, PUMPING ON THE BRAKES SEVERAL TIMES USUALLY CORRECTS THE PROBLEM. SINCE IT HAPPENS RANDOMLY, YOU NEVER KNOW WHEN IT WILL OCCUR. TOYOTA SAYS THERE IS NOTHING WRONG WITH THE BRAKES WHEN I BROUGHT IT TO THEIR ATTENTION. THEY SAID IT IS COMMON WITH PRIUSES. THIS IS NOT TRUE. I OWN A 2007 PRIUS AND NEVER HAD THIS PROBLEM. THIS PROBLEM HAS BEEN MENTIONED SEVERAL TIMES BY OTHER 2010 PRIUS OWNERS ON THE PRIUSCHAT.COM WEBSITE. *TR

2010 TOYOTA PRIUS III, PURCHASED DECEMBER 2009 FROM DCH BRUNSWICK TOYOTA, NORTH BRUNSWICK, NJ 08902 I EXPERIENCED ATLEAST 3 DIFFERENT INCIDENTS OF THE FOLLOWING, SOMETIMES AT THE SAME SPOT ON A ROAD - WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. *TR

MY 2010 PRIUS IV PURCHASED IN JUNE, 2010 HAS ON SEVERAL OCCASIONS WHEN I BRAKE AT SLOW SPEEDS AND I CROSS OVER A BUMP IN THE ROAD THE CAR MOMENTARY SURGES FORWARD. *TR

I PURCHASED A NEW TOYOTA PRIUS 2010 IN DECEMBER 2009. ALMOST IMMEDIATELY I NOTICED BRAKING WAS 'ODD' AND I FELT LIKE WHEN I WOULD BRAKE SOMETIMES, THE CAR JOLTED FORWARD BEFORE STOPPING. AFTER SOME SELF MONITORING, I REALIZED THIS PARTICULARLY HAPPENED WHEN CROSSING RAILROAD TRACKS NEAR MY HOME EN ROUTE TO WORK. I HAVE NOT HAD AN ACCIDENT BUT INSTEAD, HAVE TRIED TO BRAKE MORE SLOWLY AND IN GENERAL THIS HAS HELPED. HOWEVER, A FEW TIMES IN TRAFFIC I HAVE HAD TO STOP ABRUPTLY AND ABOUT HALF THE TIME IT DOES THE SAME THING, CAUSING ME TO FULLY SLAM ON THE BRAKES. IN THE PAST I HAVE HAD SEVERAL TOYOTA CARS AND RARELY NEEDED THE FULL FORCE OF MY ANTI-LOCK BRAKES IN SUCH SITUATIONS. I HAVE REPORTED THIS PROBLEM TO THE DEALER AND HE REQUESTED I WAIT UNTIL THE 'BREAK-IN' PERIOD WAS OVER BEFORE MAKING ANY DECISIONS. THAT BREAK-IN PERIOD WAS DEFINED AS 5000 MILES AND I AM NOW AT ABOUT 4800, AND THE PROBLEM HAS NOT CHANGED. WHEN I REPORTED IT TO THE DEALER, I HAD ABOUT 3000 MILES ON THE CAR, AND IT WAS ABOUT ONE MONTH AFTER PURCHASE (EARLY JANUARY). AT THE TIME, THE BRAKES WERE CHECKED AND NO PROBLEM WAS IDENTIFIED. TODAY I CONTACTED THE DEALER ABOUT TURNING THE VEHICLE BACK IN SINCE I AM CONCERNED AND NOT HAPPY WITH THE VEHICLE'S PERFORMANCE. *TR

I HAVE BEEN DRIVING MY 2010 PRIUS FOR ALMOST 6 MONTHS NOW AND HAVE EXPERIENCED THE CAR JERKING FORWARD AND FOR A FEW SECONDS SPEEDING UP AS IF THE BRAKE DOESN'T WORK. THIS HAPPENS SPECIFICALLY IF A POTHOLE OR BUMP IN THE ROAD IS HIT AND I'M BRAKING. MOSTLY WHEN SLOWING DOWN BY HITTING THE BRAKE. I ACTUALLY NOTICED THIS ALMOST IMMEDIATELY WHEN I BOUGH THE CAR BUT SINCE I'VE BEEN READING UP A LOT ABOUT THE 2010 PRIUS NOT IN THE TOYOTA RECALL LIST, I THOUGHT IT IS IMPORTANT TO REPORT IT AND GET IT FIXED. ONE EXPERIENCED THE STRANGEST FEELING WHEN THIS HAPPENS. ALMOST AS IF THE BREAK PEDAL IS HIT AND THE CAR JERKS FORWARD AS IF THE PEDAL IS STUCK AND THE CAR BODY MOVES FORWARD. *TR

I BOUGHT TOYOTA PRIUS 2010 IN EARLY DECEMBER 2009 AND HAVE EXPERIENCED AT LEAST FIVE TIMES BRAKE PROBLEM. I BASICALLY CAN'T MAKE MY CAR STOP EFFECTIVELY WHEN I HIT THE BRAKE. IT IS WORSE WHEN YOU DRIVE FAST OR IN A SNOWY OR ICY DAYS. NOW I HAVE TO SLOW DOWN WAY BEFORE THE STOP SIGN SO I CAN AVOID THE BRAKE PROBLEM, AND I WOULDN'T LET ANYONE ELSE TO DRIVE THE CAR FOR THE FEAR OF CAR ACCIDENT. *TR

PRIUS 2010. INTERMITTENTLY LOSE BRAKING ABILITY. ESPECIALLY WHEN ROAD IS WET AND UNEVEN. WHEN COMING TO A STOP LIGHT AND TRAVELING RELATIVELY SLOWLY, IF THE VEHICLE GOES OVER UNEVEN PAVEMENT (POTHOLE OR JUST "RUBBLY"), IT'S AS IF THE ABS GETS CONFUSED AND VERY TEMPORARILY GIVES UP. THIS IS IN CITY DRIVING. STARTING FROM UNDER 20 MPH. TRYING TO STOP AT A LIGHT AND WITH CARS IN FRONT OF ME. I HAVE DRIVEN THE EXACT SAME ROUTE IN OTHER CARS AND NOT HAD THE SAME PROBLEM. (PRIOR VEHICLE WAS BMW 528I (MODEL YEAR 2000). THIS IS A ROUTE I DRIVE DAILY (BETWEEN DROPPING MY DAUGHTER AT SCHOOL AND GOING TO WORK.) I HAVE OBSERVED THE PROBLEM MULTIPLE TIMES. *TR

I HAVE HAD MY 2010 TOYOTA PRIUS IV SINCE AUGUST 2009. OVER THE PAST TWO TO THREE MONTHS, I NOTICE THAT SOMETIMES WHEN I BRAKE, MY CAR JUMPS FORWARD A LITTLE BIT BEFORE BRAKING. IT FEELS LIKE SKIDDING ON ICE BUT THERE IS NO ICE AROUND. IT HAPPENS AT LEAST A FEW TIMES EVERY WEEK. I HAVE BEEN LUCKY SO FAR THAT THIS ISSUE HASN'T CAUSED AN ACCIDENT. I NOW MAKE SURE I HAVE EXTRA SPACE WHEN BRAKING BECAUSE I CAN'T SEEM TO FIND A REASON FOR THIS HAPPENING. THERE IS NO WAY TO PREDICT WHEN THE BRAKES WILL REACT THAT WAY. I AM PLANNING ON CONTACTING MY DEALERSHIP TODAY. *TR

2010 PRIUS BRAKE SURGE WHEN HITTING BUMP IN ROAD WHEN BRAKE IS ENGAGE. *TR
