2010 Toyota Prius Complaint Log

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

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

2010 TOYOTA PRIUS. I PURCHASED A 2010 TOYOTA PRIUS SERIES V IN JULY 2010 ... I HAVE NOTICE THAT WHEN GOING OVER A "POTHOLE" OR VERY ROUGH PAVEMENT THAT THE VEHICLE DOES SOMEWHAT SPEED UP AND HAVE A MOMENTARY LOSS OF BRAKING CAPABILITY. STEPPING ON THE BRAKE SEEMS TO ALLEVIATE THE SITUATION. SEEMS TO INTERMITTENT AND DID NOT HAPPEN ON ANY SPECIFIC DATE OR CAUSE AN ACCIDENT . *TR

EXPERIENCE SUDDEN LOSS BRAKING POWER WHEN MY PRIUS HIT A POTHOLE WHILE APPLYING THE BRAKE PEDAL. THE CAR REGAIN BRAKING POWER AFTER SHORT PERIOD OF TIME. THIS ISSUE HAPPENED MULTIPLE TIMES. I'M CONCERN MY CAR MAY HIT OTHER VEHICLE OR PEDESTRIAN IN THE FUTURE IF I WOULD NOT STOP THE CAR PROPERLY. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED HIS VEHICLE ACCELERATES ON ITS OWN WHEN HE STEPS ON THE BRAKES. THE CONTACT TOOK HIS VEHICLE TO THE DEALER AND THEY STATED THERE WAS NO PROBLEM WITH THE ACCELERATOR PEDAL. THE CONTACT STATED HE HEARD ABOUT THE PROBLEM ON THE NEWS AND HE WAS REPORTING THE PROBLEM. THE FAILURE MILEAGE WAS 2,010.

I OWN A 2010 PRIUS, PURCHASED 7/22/09. I HAVE EXPERIENCED A SUDDEN SURGE WHEN TRAVELING OVER A BUMP OR LARGE POTHOLE. THE CAR MOMENTARILY SURGES AND FEELS SLIGHTLY OUT OF CONTROL. THIS HAS HAPPENED ABOUT A DOZEN TIMES IN THE 6 MONTHS I HAVE OWNED THE VEHICLE. I AM CONCERNED ABOUT MY SAFETY AND THIS IS WHY I AM WRITING TO YOU. *JB

TL*THE CONTACT OWNS A 2010 PRIUS. WHILE DRIVING APPROXIMATELY 5 MPH ON UNEVEN PAVEMENT THE VEHICLE LUNGED FORWARD AND SHE WAS FORCED TO ENGAGE THE BRAKE PEDAL TWICE TO STOP THE VEHICLE. THE FAILURE OCCURRED 10 TIMES PRIOR TO HAVING IT DIAGNOSED BY THE DEALER. THE DEALER STATED THAT NOTHING WAS WRONG WITH THE VEHICLE. THE FAILURE MILEAGE WAS 4. THE CURRENT MILEAGE WAS 3,800. UPDATED 03/12/10. *LJ THE CONSUMER STATED THE DEALER FIX THE PROBLEM AS SOON AS THE RECALL WAS ANNOUNCED. UPDATED 07/13/10*JB

2010 PRIUS BOUGHT IN JULY OF 2009. SIMILAR PROBLEM TO WHAT IS CURRENTLY BEING INVESTIGATED. WHEN COMING TO A STOP (USUALLY FROM HIGHWAY SPEED) ON A ROAD WITH POTHOLES, THE CAR WILL HIT A POTHOLE AND WILL LURCH FORWARD, AS IF I HAD TAKEN MY FOOT OFF OF THE BRAKE. SO FAR, CONTINUED PRESSURE ON THE BRAKE PEDAL HAS ALWAYS STOPPED ME IN TIME. *TR

I HAVE A 2010 PRIUS AND I HAVE EXPERIENCED FREQUENT BRAKING LOSS WHEN DRIVING OVER BUMPS WHILE BRAKING. THE BRAKES RELEASE MOMENTARILY. I HAVE EXPERIENCED THIS MANY TIMES!! IT IS DEFINITELY DANGEROUS. *TR

TOYOTA PRIUS 2010. PROBLEM REPORTED TO DEALER 12-18-2010. BRAKES BECOME INOPERATIVE WHEN PASSING OVER UNEVEN SURFACES, VEHICLE ALSO AT THIS TIME VEHICLE LURCHES FORWARD. THIS OCCURS FREQUENTLY. CONTRARY TO YOUR FORM REQUIREMENTS THERE IS NO ONE "APPROXIMATE INCIDENT DATE". SHIFTER SOMETIMES IS DIFFICULT TO PUT INTO NEUTRAL, RATHER IT WILL INSTEAD GO FROM DRIVE TO REVERSE. IF THERE IS ALSO A SUDDEN ACCELERATION PROBLEM, THIS COULD BE A BIG PROBLEM WHEN TRYING TO REGAIN CONTROL. *TR

I HAVE A 2010 TOYOTA PRIUS PURCHASE IN 9/2009. WHEN I SLOW DOWN TO STOP AND GO OVER A BUMP IT FEELS AS THOUGHT THE POWER BREAKS GO OUT AND THE VEHICLE SURGES FORWARD. THIS HAS OCCURRED SINCE WE PURCHASED THE VEHICLE. THE ORIGINAL EXPLANATION WAS THAT WE JUST NEED TO GET USED TO THE TRANSITION FROM GASOLINE POWER TO ELECTRIC POWER. HOWEVER, I DON'T FEEL THAT IS SUFFICIENT AS IT IS A VERY DANGEROUS SURGE. *TR

I HAVE NOTICED AN ISSUE WITH THE BRAKES NOT WORKING FOR A SECOND WHEN I AM GOING DOWNHILL IN THE PARKING GARAGE, AND GOING OVER A SPEED BUMP, WHEN I GO OVER THE BUMP WHILE THE BRAKES ARE SLIGHTLY PRESSED, IT MOMENTARILY LOSES BRAKING AFTER GOING OVER THE BUMP. I THINK IT IS AN ISSUE WITH SWITCHING FROM REGENERATIVE BRAKING, TO REGULAR MECHANICAL BRAKING. I AM ABLE TO REPEAT THE ISSUE CONSISTENTLY IN ONE LOCATION IN A PARKING STRUCTURE THAT I PARK IN. I NOTICED IT AROUND OCT 2009 AND HAVE BEEN NOTICING IT SINCE THEN. *TR

PROBLEM VEHICLE: 2010 TOYOTA PRIUS PURCHASED IN SEPTEMBER 2009. WHEN FOOT IS ON OR OFF BRAKE AT SPEEDS < APPROX 45 MPH, AND A LARGE BUMP/POT HOLE/ETC IS TRAVERSED, THE BRAKES FAIL FOR ABOUT A SECOND (WHICH FEELS LIKE AN UNCONTROLLED ACCELERATION). FOR THAT SECOND THE CAR IS UNCONTROLLED. THIS HAS HAPPENED AT LEAST 15 TIMES SINCE SEPTEMBER 2009. THIS IS ESPECIALLY DANGEROUS IS SUDDEN BRAKING IS REQUIRED OR ROAD CONDITIONS ARE HAZARDOUS. *TR

1. LOW DRIVING SPEEDS (<30 MPH), MOVING DOWN HILL, DECELERATING AS APPROACHING A STOP SIGN. 2. WHEN THE FRONT WHEEL STRIKES POT HOLE, THE BRAKING ACTION STOPS/DECREASES, THE CAR MOVES FORWARD MORE QUICKLY. IN THE CURRENT CASE, THERE ARE A SERIES OF THREE POT HOLES, SO HITTING EACH POT HOLE INCREASES THE FORWARD MOTION DESPITE HAVING BREAK PEDAL DEPRESSED. CONSEQUENCE, IS IMMEDIATE DIFFICULTY TO COME TO A STOP AT A STOP SIGN. 3. NO CURRENT CORRECTION HAS BEEN ATTEMPTED. *TR

WE HAVE AN ONGOING PROBLEM WITH OUR 2010 PRIUS, PURCHASED IN 9/09. WHEN GOING OVER A DEPRESSION IN THE ROAD, OR A BUMP, WHEN BRAKES ARE PRESSED, WE FEEL LIKE THE CAR IS BUCKING/ACCELERATING. CLEARLY, IT'S REALLY THAT THE BRAKES AREN'T WORKING MOMENTARILY BUT IT'S FRIGHTENING. IF WE HAD TO STOP, WE COULDN'T. THIS HAPPENS EACH AND EVERY TIME IN THOSE CIRCUMSTANCES. *TR

MY PRIUS 2010 3RD GENERATION MODEL'S BRAKES SEEM TO GO OUT WHEN BRAKING OVER UNEVEN ROAD. THIS HAS HAPPENED MORE THAN 10 TIMES STARTING FROM THE FIRST WEEK I GOT THE CAR. ESPECIALLY GOING OVER POTHOLES, THE CAR LURCHES FORWARD SEVERAL FEET. I CALLED THE DEALER SERVICE DEPARTMENT AND THEY SAID THERE WAS NOTHING THAT COULD BE DONE TO REMEDY THE BRAKES. I WAS TOLD TO CALL BACK IF THERE WAS A RE-CALL ISSUED. *CN

TWICE MY 2010 PRIUS HAD A DELAY WHEN APPLYING THE BRAKES. MOMENTARILY I THOUGHT I HAD A BRAKING FAILURE. *TR

I HAVE 2010 PRIUS. I AM EXPERIENCING AN ENERGY SURGE FROM MY BACK WHEELS WHEN I STEP ON MY BRAKES WHILE SIMULTANEOUSLY GOING OVER A BUMPY SURFACE LIKE RAIL ROAD TRACKS, POT HOLE OR ROUGH GROUND. IT OCCURS SEVERAL TIMES A WEEK. THE RESULT IS THAT MY CAR SUDDENLY SPEEDS FORWARD WHEN I LEAST WANT IT TO - I AM BRAKING. I HAVE IT THRUST ME INTO AN INTERSECTION. I REPORTED IT TO MY SERVICE DEPT IN NOV 09. THEY TOLD ME THEY HAD NEVER HEARD OF THIS PROBLEM BEFORE AND HAD NO OTHER COMPLAINTS. WITH A FRONT WHEEL DRIVE I DIDN'T UNDERSTAND WHY THE POWER SEEMED TO BE COMING FROM THE BACK WHEELS. NOW I AM ASSUMING IT IS SOME KIND OF CONNECTION TO THE ABS SYSTEM. THIS HAPPENS MOST NOTABLY AT LOWER SPEEDS, ROUNDING A CORNER. BUT I THINK IT MAY ALSO BE HAPPENING ON THE HIGHWAY, BUT THE SURGE IS HARDER TO DETECT AT HIGHER SPEED. *TR

BRAKE FAILURE WHEN DRIVING AT SLOW SPEEDS OVER BUMPY SURFACE. 2010 TOYOTA PRIUS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE INTEGRATED NAVIGATION SYSTEM WAS PROVIDING INACCURATE READINGS WHEN ENTERING ANY STREET ADDRESS. HE NOTICED THAT THE NAVIGATION SYSTEM WOULD PLACE HIM ABOUT ONE QUARTER OF A MILE OFF FROM HIS DESTINATION. BOTH THE DEALER AND MANUFACTURER ADVISED THE CONTACT THAT THERE WAS NOTHING WRONG WITH THE NAVIGATION SYSTEM AND ADVISED HIM TO TAKE THE VEHICLE THROUGH THE ARBITRATION PROCESS. THE CURRENT MILEAGE WAS 28,000 AND THE FAILURE MILEAGE WAS 10. UPDATED 04/25/2011*BF UPDATED 10/26/11

RE: 2010 PRIUS. WHEN BRAKING OVER A POTHOLE, THE CAR SURGED FORWARD SUDDENLY (SUDDEN ACCELERATION DESPITE BRAKING). *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 45 MPH AND ATTEMPTING TO ENGAGE THE BRAKE PEDAL IT EXTENDED TO THE FLOOR; HOWEVER, WITHIN A FEW SECONDS THE BRAKE WOULD RESPOND. SHE EXPERIENCED THE BRAKE FAILURE THREE TIMES; DURING THE SECOND FAILURE THE BRAKES DIDN'T RESPOND AND SHE COLLIDED INTO A VEHICLE AND INJURED HER NECK. SHE HAS NOT TAKEN THE VEHICLE TO THE DEALER SINCE THE FAILURE OCCURRED ONLY WHEN SHE HIT A BUMP IN THE ROAD. SHE WILL TAKE THE VEHICLE TO THE DEALER TO BE DIAGNOSED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 3,000 AND THE CURRENT MILEAGE WAS 10,000. UPDATED 03/09/10. *LJ THE CONSUMER STATED SHE EXPERIENCED BRAKE PROBLEMS WITH HER VEHICLE TWICE WHILE SLOWING DOWN TO COME TO A STOP OR TO MAKE A TURN. THE CONSUMER STATED SHE FELT A RELEASE OF THE BRAKES AND A SURGE AFTER HITTING A POT HOLE IN THE ROAD. TWO AGO, WHILE DRIVING, SHE HIT A BUMP IN THE ROAD AND SHE FELT THE SAME ACCELERATION, LIKE THE GAS PEDAL WAS APPLIED, BUT SHE WAS BRAKING AT THE TIME. THE CONSUMER WAS INVOLVED IN AN ACCIDENT WHERE SHE WAS REAR-ENDED. SHE WAS AT A STOP WITH HER FOOT ON THE BRAKE. THE CONSUMER STATED WHEN SHE WAS HIT, SHE WAS PUSHED FORWARD AND HIT THE VEHICLE IN FRONT OF HER. UPDATED 05/13/10

MY 2010 PRIUS HAS ISSUES WITH BRAKING UNDER CERTAIN CONDITIONS. IT SEEMS TO HAPPEN MOSTLY WHEN I AM BRAKING ON BUMPY ROADS OR GOING OVER RAILROAD TRACKS. WHEN THIS HAPPENS, IT LITERALLY FEELS LIKE THE CAR IS SURGING FORWARD WITH ENOUGH FORCE TO ACTUALLY MAKE ME FEEL LIKE IT IS ACCELERATING. I THOUGHT IT WAS JUST ME BUT, THEN, MY WIFE HAD THE SAME ISSUE JUST THE OTHER DAY. IN ADDITION TO THE BUMPY ROAD, IT WAS ICY AND IT CAUSED HER TO SLIDE THROUGH AN INTERSECTION. TODAY, I JUST HEARD ABOUT THIS ISSUE FROM A CO-WORKER SO, I HAVE DECIDED TO ADD MINE TO THE LIST. *TR

SINCE I BOUGHT MY 2010 TOYOTA PRIUS, I HAVE BEEN NOTICING THAT WHEN I GO OVER A BUMP OR POTHOLE IN THE ROAD THAT THE CAR LURCHES FORWARD AND SEEMS TO ACCELERATE OR I CAN'T BRAKE. IT OCCURS A FEW TIMES A WEEK SINCE I BOUGHT IT IN SEPT..2009 IT IS CURRENTLY AT THE DEALER AND I DON'T KNOW IF THEY WILL BE ABLE TO FIX THE PROBLEM. THEY DIDN'T SEEM VERY CONFIDENT THAT THEY WOULD BE ABLE TO. *TR

I BOUGHT A 2010 PRIUS IN AUGUST 2009. WHEN I APPLY THE BRAKES ON A BUMPY ROAD THERE IS A LOSS OF BREAKING FOR A SHORT TIME. IT FEELS LIKE A SURGE IN ACCELERATION BEFORE THE BRAKES WORK AGAIN. I DO NOT KNOW IF IT IS A SAFETY ISSUE BUT IT IS VERY DISCONCERTING. *TW

IT APPEARS THAT THE CAR EITHER DOES NOT RESPOND OR EVEN ACCELARATES WHEN BRAKING ON UNEVEN SURFACE. IT HAPPENED TO ME MORE THAN 10 TIMES, I HAVE THE CAR FOR 4.5 MONTHS.

I HAVE A 2010 TOYOTA PRIUS - IT HAS 6,000 MILES ON IT. TWO TIMES THE BRAKES HAVE FAILED TO ENGAGE WHEN I HAVE STEPPED ON THE BRAKE PEDAL. IT TAKES APPX. 2 TO 3 SECONDS BEFORE THE BRAKES ENGAGE. *TR

I PURCHASED A 2010 PRIUS IN SEPTEMBER 2009. WITHIN THE FIRST FEW DAYS OF DRIVING I EXPERIENCED A DISCONNECT WHEN I WOULD HIT THE BRAKE WHEN GOING OVER A BUMP. THIS HAS HAPPENED AT LEAST 20 TIMES SINCE. I AM CONTACTING THE DEALER BUT I HAVE NOT DRIVEN THE CAR VERY MUCH BECAUSE I AM UPSET ABOUT MY SAFETY AS WELL AS OTHERS ON THE ROAD. *TR

I PURCHASED A 2010 TOYOTA PRIUS IN SEPTEMBER. I HAVE NOTICED THAT DURING THE FIRST FEW MINUTES OF DRIVING AFTER THE CAR HAS BEEN STARTED, IF I GO OVER A SPEED BUMP THE CAR IS MUCH MORE DIFFICULT TO BRAKE TO A STOP. AFTER THE CAR IS WARMED UP, THIS ISSUE GOES AWAY. THERE IS A SPEED BUMP I HAVE TO GO OVER ON MY WAY HOME FROM WORK AND HAVE EXPERIENCED THE PROBLEM CONSISTENTLY. *TR

I HAVE A 2010 PRIUS PURCHASED IN SEPTEMBER OF 2009. IT NOW HAS JUST OVER 5000 MILES ON IT. SINCE THE BEGINNING, PROBABLY THE FIRST WEEKEND I OWNED THE CAR, WHEN BRAKING IF I HIT A BUMP IN THE ROAD, UNEVEN SURFACE, OR A POTHOLE OR SOMETHING, THE CAR OFTEN FEELS LIKE IT LURCHES FORWARD AND I HAVE TO IMMEDIATELY RELEASE AND REBRAKE. THE CAR FEELS OUT OF CONTROL. I HAVE VERY OFTEN FELT LIKE I NARROWLY MISSED LURCHING FORWARD INTO THE CAR IN FRONT OF ME. THE TOYOTA DEALERSHIP SERVICE DEPARTMENT INSISTS THEY ONLY KNOW OF RECALLS REGARDING THE STICKING ACCELERATOR PEDALS, NOTHING ABOUT THIS BRAKING ISSUE. YET I READ PLENTY ONLINE ABOUT THIS PROBLEM, SO I KNOW IT ISN'T ONLY HAPPENING TO ME. WHAT CAN YOU DO?? I'VE LISTED ALL THREE TYPES OF BRAKES IN THE EQUIPMENT AREA OF THIS FORM, BECAUSE I DON'T KNOW WHAT IT IS - SOMETHING ABOUT THE HYBRID BRAKING SYSTEM ALSO CHARGING THE ENGINE? ALSO I LISTED THE DATE AS THE DAY AFTER I BOUGHT THE CAR BUT THIS IS ONGOING, NOT A SINGLE INCIDENT BY ANY MEANS. *TR

CRASH DUE TO BRAKE FAILURE, SUDDEN UNINTENDED,SUDDEN UNCONTROLLED DANGEROUS ACCELERATION, SURGING FORWARD MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING EXTREMELY LOW SPEED UNDER 5 MPH ON AN UNEVEN BUMPY COUNTRY ROAD SURFACE, POTHOLE, OR BUMP, LURCHED FORWARD SKIDDED SIDE WAYS INTO TREE. FREQUENTLY OCCURS. MAJOR COLLISION DAMAGE, IN REPAIR SHOP 1 MONTH. *TR UPDATED 04/27/10.*LJ UPDATED 08/11/10

TL*THE CONTACT HAS 2010 TOYOTA PRIUS. THE CONTACT WAS ENGAGING THE BRAKE PEDAL WHILE DRIVING 15 MPH INTO A POT HOLE. ONCE THE CONTACT DROVE INTO THE POT HOLE THE BRAKES RELEASED AND SHE WAS FORCED TO PUMP THE BRAKES IN ORDER TO STOP THE VEHICLE. THE CONTACT STATED THAT THERE WAS A LOUD SCREECHING NOISE AS WELL. THE FAILURE MILEAGE WAS 600. THE CURRENT MILEAGE WAS 5,600. *CN UPDATED 02/17/10

JUST WANTED TO ADD MY TWO CENTS WORTH THAT THE BRAKES ON MY 2010 PRIUS AREN'T RIGHT. WHEN I HIT A POTHOLE WHILE BRAKING, THE CAR LURCHES FORWARD A FEW MORE FEET. IT HAS ALMOST PUT ME INTO ONCOMING TRAFFIC A COUPLE OF TIMES. THIS HAS HAPPENED NUMEROUS TIMES. I PURCHASED MY CAR ON AUGUST 28, 2009. PLEASE LET ME KNOW WHEN REPAIRS AND ADJUSTMENTS WILL BE AVAILABLE TO THE PUBLIC. *TR

I HAVE A 2010 TOYOTA PRIUS PURCHASED IN JULY 2009. DURING OWNERSHIP I EXPERIENCED WHEN THERE WAS A CREASE, HOLE OR BUMP IN THE ROAD WHEN BRAKING - IT ACCELERATING AND LUNGES. I AVOIDED SITUATIONS LIKE THAT AND WHEN THE RECALL CAME, I TOOK IT TO BUTLER TOYOTA (ALSO HAD THE FLOOR MAT HOOKS INSTALLED PRIOR), ON APRIL 5, 2010. THEY SUPPOSEDLY FIXED IT. ABOUT A WEEK LATER, I CAME UPON A MANHOLE COVER IN A ROAD WHILE BRAKING AND MAKING A TURN SO GOING SLOW, AND THE SAME THING HAPPENED. THE NEXT DAY I PURPOSELY WENT THROUGH IT TO "TEST" AND IT DID THE SAME THING BUT LUNGE INTO THE OTHER LANE. I WAS SCARED AND CALLED BUTLER TOYOTA. THEY TOLD ME TO CALL NATIONAL TOYOTA TO REPORT. THEY CONTACT BUTLER AND I WENT BACK IN MAY 21, THEY DID NOT REPAIR IT AND "SHRUGGED" THEIR SHOULDERS SAYING IT'S THE ABS. THEY OFFERED TO HAVE A FIELD TECH PERSON COME DRIVE MY CAR. I CALLED NATIONAL AGAIN AND THEY SEEM TO BE "MEDIATING" THIS WITH BUTLER. I FOUND A REPORT FROM CONSUMERAFFAIRS.COM THAT THIS VERY SIMILAR ISSUE WAS OCCURRING BACK IN 2008 AND THEY CALLED IT "TRACTION CONTROL". NO ONE FROM TOYOTA HAS TOLD ME THIS. I WANT IT FIXED OR A DIFFERENT CAR. I HAVE A TEENAGE WITH A PERMIT AND IF HE WAS DRIVING THIS AND IT OCCURRED, HE WOULD PROBABLY RUN INTO SOMEONE BECAUSE IT TAKES YOU BY SURPRISE. I DO FEAR HIM DRIVING IT DUE TO HIS INEXPERIENCE AND I FRANKLY AM CONCERNED AND AM VERY CAUTIOUS AS A RESULT. *TR

OWN A 2010 PRIUS. HAVE EXPERIENCE INTERMITTENT BRAKE ISSUES. THE BRAKES SEEM TO NOT FUNCTION PROPERLY WHEN THEY APPLIED OVER UNEVEN SURFACES. THE CAR FEELS LIKE IT IS "SLIDING" OR "HYDROPLANING" FOR A BRIEF MOMENT, THEN THE BRAKES "CATCH" AGAIN. I WAS INVOLVED IN AN ACCIDENT ON SEPTEMBER 24, 2009 AND NEVER THOUGHT ABOUT THE ISSUE WITH THE BRAKES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN HE HIT A BUMP IN THE ROAD OR A POTHOLE AND DEPRESSED THE BRAKE PEDAL, THE BRAKES SEEMED TO RELEASED OR LET GO; INSTEAD OF SLOWING DOWN, THE VEHICLE WOULD CONTINUE MOVING AT THE SAME SPEED. HE NOTICED THE ISSUE ON AN INTERMITTENT BASIS AND ONLY WHEN ON A ROUGH OR BUMPY SURFACE. HE HAD NOT TAKEN THE VEHICLE TO THE DEALERSHIP BUT CALLED; HE WAS TOLD THAT THEY WERE LOOKING INTO THE PROBLEM. HE HAD NOT CALLED THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS APPROXIMATELY 7,200. THE FAILURE MILEAGE WAS APPROXIMATELY 2,100.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES FAILED WHILE DRIVING APPROXIMATELY 25 MPH ON A NORMAL ROAD SURFACE. THERE WAS MINIMAL HESITATION WHEN THE BRAKE PEDAL WAS ENGAGED. THE FAILURE MILEAGE WAS 1,200 AND THE CURRENT MILEAGE WAS 9,700.

MY NEW 2010 PRIUS ACCELERATED ON IT'S OWN AS I WAS BRAKING AND SLOWLY APPROACHING THE CAR IN FRONT OF ME THAT WAS STOPPED AT A STOP LIGHT QUITE SOME DISTANCE AWAY. MY CAR HAD ALMOST COME TO A COMPLETE STOP WHEN SUDDENLY THE ENGINE REVVED ON IT'S OWN AS MY FOOT WAS STILL ON THE BRAKE. I HAD TO PRESS DOWN SO HARD ON THE BREAK TO KEEP IT FROM SURGING FORWARD THAT THE ABS LIGHT CAME ON AND THEN THE CAR'S REV WENT DOWN ON IT'S OWN AND ALL WAS BACK TO NORMAL AND HADN'T HAPPENED AGAIN SINCE. I BROUGHT THE CAR TO THE DEALER AND THEY KEPT IT FOR TWO DAYS BUT DIDN'T FIND ANYTHING WRONG WITH IT. I HAVE TWO SMALL CHILDREN AND BOUGHT THIS CAR FOR A NUMBER OF REASONS, SAFETY BEING ONE OF THE IMPORTANT ONES. I AM NO LONGER FEELING SAFE. THIS WAS NOT THE FLOOR MATS, OR A SUDDEN STOP MISTAKING ONE PEDAL FOR ANOTHER, OR ANY OTHER FORM OF DRIVER ERROR. THIS WAS THE CAR! PLEASE HELP TO DISCOVER THE CAUSE AND MAKE TOYOTA FIX IT BEFORE SOMEONE GETS HURT OR KILLED. THANK YOU, CHRIS TOPPIN *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 5 MPH OVER RAILROAD TRACKS WITH HIS FOOT ON THE BRAKE PEDAL, THE VEHICLE ACCELERATED ON ITS OWN. THE FAILURE DOES NOT OCCUR WHILE DRIVING OVER SMOOTH ROAD SURFACES. THE DEALER HAS NOT BEEN CONTACTED. NO REPAIRS WERE MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 2000 AND THE CURRENT MILEAGE WAS 11000.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES WERE MOMENTARILY UNRESPONSIVE AT LOW SPEEDS WHEN DRIVING APPROXIMATELY 10 MPH OVER A POTHOLE. SHE STATED THAT THE FAILURE OCCURRED 50% OF THE TIME SHE DROVE OVER A POTHOLE OR BUMPY SURFACE. SHE CALLED THE DEALER AND WAS TOLD THAT THE ABS WAS THE CAUSE AND IT WAS NORMAL. SHE CALLED THE MANUFACTURER AND WAS UNABLE TO SPEAK WITH A REPRESENTATIVE. THE VEHICLE HAS NOT BEEN REPAIRED TO-DATE. THE VEHICLE IDENTIFICATION NUMBER WAS NOT AVAILABLE AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS APPROXIMATELY 4,000. THE FAILURE MILEAGE WAS APPROXIMATELY 500.

PRIUS, WHEN BRAKE WAS DEPRESSED IT SPED UP WHEN DRIVING SLOW AND HITTING A POT HOLE THIS HAPPENED TWICE BEFORE TOYOTA CAME OUT WITH THE INFORMATION ABOUT THE BRAKES AND ONCE SINCE THE INFORMATION HAS BEEN IN THE NEWS. I BOUGHT THE CAR IN AUGUST HAD THE FIRST INCIDENT IN SEPT. ONE AROUND CHRISTMAS AND ONE THIS MONTH. DIDN'T REALLY KNOW WHAT WAS HAPPENING UNTIL NOW. *TR

WHILE BRAKING AND TURNING AND GOING OVER A SMALL BUMP MY PRIUS SEEMS TO LOSE ITS BRAKES AND ACCELERATE FOR A SPLIT SECOND . IT HAS HAPPENED ABOUT 4 TIME IN THE LAST 6 MONTHS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING OVER A ROUGH SURFACE, THE BRAKES FAILED TO STOP THE VEHICLE. HE STATED THAT THE ANTI-SKID ACTIVATED WHILE DRIVING ON THAT TYPE OF SURFACE. THE FAILURE OCCURRED 100% OF THE TIME ON ROADS WITH A ROUGH SURFACE. THE DEALER TOLD HIM THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. HE HAD NOT SPOKEN WITH THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS 13,202. THE FAILURE MILEAGE WAS APPROXIMATELY 600.

ON THREE OCCASIONS, WHILE DRIVING ON CLEAN, DRY ROAD SURFACES, MY 2010 PRIUS SUDDENLY AND BRIEFLY ACCELERATED WITHOUT ANY WARNING AFTER I DROVE OVER MINOR BUMPS AND, ONE 1 OCCASION, A MANHOLE COVER, WHILE BRAKING. THE SENSATION WAS THAT OF THE ENGINE SUDDENLY SURGING AND ACCELERATING. I WAS FORTUNATELY ABLE TO APPLY HARDER PRESSURE TO THE BRAKE PEDAL, REGAINED CONTROL OF THE VEHICLE AND AVOIDED CRASHING INTO THE CAR IN FRONT OF ME. I SPOKE WITH A TOYOTA FIELD TECHNICAL SPECIALIST TODAY WHO TOLD ME THAT THE MECHANICS OF THE CAR ARE SUCH THAT IF A WHEEL HITS A BUMP OR MOVES ONTO A SURFACE THAT CAUSES IT TO ROTATE AT A DIFFERENT RATE VERSUS THE OTHER WHEELS, THE CAR THINKS IT IS GOING INTO A SKID, AND THE ABS SYSTEM KICKS IN. ALSO, THE SYSTEM THAT GENERATES ENERGY TO RECHARGE THE BATTERY, WHICH ALSO EFFECTIVELY BRAKES THE CAR, SUDDENLY CEASES TO OPERATE. CONSEQUENTLY, YOU HAVE THE SENSATION OF ACCELERATION WHEN IN FACT, ACCORDING TO THE TOYOTA SPECIALIST, THE CAR STOPPED DECELERATING. NONETHELESS, THIS SUDDEN DECELERATION IS UNEXPECTED, AND IF I WAS NOT FOCUSED AT THOSE EXACT MOMENTS AND FAILED TO IMMEDIATELY APPLY SIGNIFICANT PRESSURE TO THE BRAKE PEDAL, I COULD HAVE EASILY CRASHED INTO AN OBJECT, OR CAR, OR PERSON, IN FRONT OF ME. I DO NOT FEEL SAFE IN THIS CAR, AND AM WORRIED THAT MY WIFE OR SON COULD HAVE A MAJOR PROBLEM RESPONDING TO THIS SUDDEN LACK OF CONTROL. THERE IS GREAT POTENTIAL FOR SERIOUS INJURY OR DEATH FROM THIS TYPE OF INCIDENT. MY CAR IS ABOUT 1 MONTH OLD, WITH 1,250 MILES ON IT. I UNDERSTAND FROM THE SPECIALIST THAT TOYOTA DEALERSHIPS ON LONG ISLAND HAVE HAD AT LEAST ONE OTHER SIMILAR COMPLAINT. *TR

ON MY 2010 PRIUS IV WHICH I TOOK DELIVERY OF IN AUGUST, 2009, EVERY TIME I BRAKE, GOING OVER A POTHOLE OR LARGE BUMP, THE CAR LURCHES FORWARD EVEN THOUGH I AM STEPPING ON THE BRAKE. A FEW TIMES I ALMOST HIT THE CAR AHEAD OF ME. THIS IS AN EXTREMELY DANGEROUS SITUATION, AND COULD RESULT IN A CRASH OR POSSIBLY HITTING A PEDESTRIAN. I HOPE THIS SITUATION CAN BE RESOLVED IMMEDIATELY, BEFORE FATALITIES RESULT. I K NOW OTHER PEOPLE ARE EXPERIENCING THE SAME PROBLEM. *TR

ON OCCASION THE BRAKING ON OUR 2010 PRIUS HAS NOT FELT RIGHT. SOMETIMES WHEN BRAKING AND HITTING A BUMP OR POTHOLE, THERE SEEMS TO BE A BRIEF PERIOD WHERE THE CAR FEELS LIKE ITS ACCELERATING OR THE BRAKES ARE NOT SLOWING IT DOWN PROPERLY. KEEPING PRESSURE ON THE BRAKES GETS BY THE PROBLEM BUT IT IS VERY UNSETTLING AND I HAVE NEVER HAD THIS PROBLEM WITH BRAKES IN ANY CAR BEFORE. IT HAS HAPPENED A FEW TIMES SINCE WE BOUGHT THE CAR IN JULY 2009 BUT VERY INTERMITTENTLY. THE DATE I AM PICKING IS JUST AN APPROXIMATE DATE FOR ONE OF THE INCIDENTS. I AM REPORTING THIS NOW IN LIGHT OF THE RECENT PUBLICITY ABOUT SIMILAR EVENTS REPORTED BY OTHER OWNERS, WHICH MADE ME REALIZE WHAT I HAD BEEN NOTICING WAS A REAL ISSUE. *JB

TOYOTA PRIUS 2010. WHILE DRIVING APPROX 20 MPH OVER A POTHOLE WHILE APPLYING THE BRAKES, I FELT WHAT SEEMED LIKE THE BRAKE SLIP AND RELEASE TEMPORARILY. ALTHOUGH IT DID NOT CAUSE AN ACCIDENT, IT COULD HAVE HAD THERE BEEN A CAR CLOSER ON THE OTHER SIDE OF THE POTHOLE. *TR

OUR 2010 TOYOTA PRIUS HAS EXPERIENCED THE LOSS OF BRAKE ACTION, OR THE SENSATION OF SPEEDING UP, WHEN GOING OVER A BUMP, OCCASIONALLY AROUND CORNERS AND ON UNEVEN SURFACES. *TR

2010 TOYOTA PRIUS ACCELERATES FOR A SECOND WHEN I HIT THE BRAKES WHEN I AM PASSING OVER POTHOLES OR ICE. IT HAS HAPPENED WELLOVER 10 TIMES. *TR

I BOUGHT MY 2010 PRIUS IN JULY 2009. OVER THE COURSE OF THE FIRST 3-4 MONTHS, THERE WERE 3 OR 4 INSTANCES WHEN I FELT MOMENTARILY THAT I HAD NO BRAKING CONTROL, ALL WHILE TRAVELING AT LOW SPEED OVER BUMPY TERRAIN., AND AT LEAST TWICE WHILE IN REVERSE. I DIDN'T IDENTIFY IT AS BEING A REAL PROBLEM UNTIL THE BRAKING PROBLEM SURFACED. I AM EAGER TO HAVE MY CAR FIXED, SO THAT THERE ISN'T A CRASH IN THE FUTURE. *TR
