2010 Toyota Prius complaints

WHILE APPROACHING A STOP SIGN AND APPLYING MY BRAKE,CAR WOULD NOT SLOW DOWN. PRESSED HARDER ON BRAKE,WHEELS LOCKED UP AND MY CAR SLID THROUGH THE INTERSECTION,CAR STOPPED WHEN IT HIT THE CURVE ACROSS THE STREET. APPROX. 50 FEET. I WAS DRIVING AT 10-15 MPH WHEN APPROACHING THE STOP SIGN. THE ANTILOCK BRAKES DID NOT WORK. THERE WAS ABOUT 1-2 INCHES OF SNOW ON THE ROAD. *TR

2010 PRIUS DELAYED BRAKING - MULTIPLE TIMES. *TR

I HAVE OWNED A 2010 PRIUS SINCE AUGUST 2009. SINCE THE PURCHASE I HAVE PUT 10,000 MILES ON THE VEHICLE. TO DATE I HAVE EXPERIENCED THE BRAKING PROBLEM ON THREE SEPARATE OCCASIONS. MY HUSBAND HAD ONE EXPERIENCE. IT APPEARS THAT WHEN THE FRONT TIRES HIT AN UNEVEN OR DIFFERENT SURFACE THE BRAKES WILL DISENGAGE VERY BRIEFLY AND THEN CATCH WHEN THE TIRES HIT EVEN GROUND. *TR

WHEN BRAKING TO A STOP AT RELATIVELY LOW SPEEDS, IF YOU HIT A BUMP OR A POTHOLE, THE CAR STOPS BREAKING AND LURCHES FORWARD. THIS LASTS FOR LESS THAN A SECOND BEFORE NORMAL BRAKING RESUMES. *TR

MOMENTARY REDUCTION IN BRAKING PERFORMANCE WHILE TRAVELING OVER A BUMP AND APPLYING THE BRAKES. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 40 MPH ON UNEVEN ROADS, THE VEHICLE FAILED TO STOP IMMEDIATELY WHEN THE BRAKES WERE APPLIED. THE VEHICLE ALSO LUNGED FORWARD. THE FAILURE MILEAGE WAS UNAVAILABLE. THE CURRENT MILEAGE WAS 5300.

BOTH MY 2006 TOYOTA HIGHLANDER HYBRID AND MY 2010 TOYOTA PRIUS HAVE PREDICTABLE BRAKE LAPSES WHEN TRAVELING. I AM AWARE OF ONE SITE ON THE WAY TO WORK, AND ONE ON THE WAY HOME WHICH HAVE PREDICTABLE SURGES DURING BRAKING. I FIRST REPORTED THIS TO MY DEALER IN 2006, WHO COULD NOT REPLICATE THE EVENT IN THE NEIGHBORHOOD NEAR THE DEALER. THE PRIUS ACTS EXACTLY THE SAME. FOR MY CARS IT ALWAYS OCCURS WHEN BRAKING ON A ROAD AT THE PLACE WHERE A DESCEND TURNS INTO AN ASCEND. *TR

THE VEHICLE IS A VERY NEW PRIUS VERSION 3. THERE IS NO PROBLEM WITH THE FLOOR PADS. THERE DOES NOT SEEM TO BE A PROBLEM AT HIGHER SPEEDS. THE PROBLEM IS SHORT, UNEXPECTED BURSTS OF ACCELERATION AT LOWER SPEEDS, ESPECIALLY AS THE CAR IS SLOWING DOWN, WITH OR WITHOUT BRAKING. I BELIEVE IT OCCURS ESPECIALLY WHEN THE ENGINE SHIFTS FROM HYBRID TO ALL ELECTRIC. FOR EXAMPLE, ON A CURVING EXIT RAMP OFF A ROAD, AS THE CAR SLOWS, AND AS BRAKING AND ACCELERATION ARE RELEASED, AND THE CAR SHIFTS INTO PROPELLING ITSELF ON ELECTRIC, THERE IS A BURST OF ACCELERATION AT SOME TIME IN THIS MANEUVER. THIS HAS HAPPENED SEVERAL TIMES SINCE PURCHASING THE CAR A FEW WEEKS AGO. I SPOKE TO THE SERVICE MANAGER AT HE DEALERSHIP LAST WEEK. HE STATED HE KNEW NOTHING ABOUT THIS, AND HAD HEARD NORTHING FROM TOYOTA. HE OFFERED TO LOOK AT THE CAR IF I BROUGHT IT IN. SUBSEQUENTLY THE PRIUS PROBLEM BECAME NEWS.*TR

FEBRUARY 5, 2010 OFFICE OF DEFECTS INVESTIGATION NATIONAL HIGHWAY & TRAFFIC SAFETY ADMINISTRATION WASHINGTON DC RE: ON-LINE CUSTOMER COMPLAINT TOYOTA PRIUS 2010 DEAR MADAM OR SIR: MY HUSBAND AND I PURCHASED A PRIUS 2010 IN SEPTEMBER 2009. IN NOVEMBER 2009, I EXPERIENCED A SUDDEN JOLTING FORWARD OF MY NEW CAR AS I PULLED INTO MY DRIVEWAY. SHORTLY THEREAFTER, AS I WAS DRIVING ON A MAJOR COMMERCIAL THRUWAY IN MY AREA (ROUTE 10), I EXPERIENCED A SIMILAR UNEXPECTED ACCELERATION WHILE I WAS STOPPING AT AN INTERSECTION LIGHT (ALTHOUGH MILDER). I WAS CONCERNED AND ALARMED BY THE PROBLEM AND CALLED TOYOTA MORRISTOWN, NEW JERSEY (THE CAR DEALER WHERE WE BOUGHT THE CAR) TO REPORT THE PROBLEM. I WAS TOLD THE PROBLEM WAS NOT SERIOUS AND THAT I DID NOT NEED TO BE CONCERNED ABOUT IT.. WHILE I DID NOT REALLY BELIEVE THE DEALER'S STORY, IT DID NOT HAPPEN AGAIN SO I DID NOT PURSUE THE MATTER. AFTER TODAY'S ARTICLE IN THE NEW YORK TIMES, I NOW SEE THAT A NUMBER OF PRIUS 2010 OWNERS ARE HAVING THE SAME PROBLEM AND I WANT TO LET YOU KNOW I EXPERIENCED IT AS WELL. TOYOTA NEEDS TO FIX THIS SAFETY ISSUE AS SOON AS POSSIBLE WITHOUT EXTENSIVE INVESTIGATIONS AND DELAYS. THANK YOU FOR PROTECTING THE PUBLIC'S INTEREST IN THIS REGARD. *TR

NOTICED THE BRAKING ON MY 2010 PRIUS HAS A FEW PROBLEMS EVERY NOW AND THEN. WHEN PRESSING DOWN ON THE BRAKE PEDAL IT FEELS LIKE THE BRAKES AREN'T WORKING OR THAT THE VEHICLE IS ACCELERATING. I LIVE IN FAIRBANKS, ALASKA AND HAVING BRAKES THAT WORK IS ESPECIALLY IMPORTANT HERE WHERE THE ROADS ARE COVERED WITH ICE SIX MONTHS OF THE YEAR. I CALLED THE TOYOTA DEALERSHIP AND INFORMED THEM OF THE PROBLEM AND THEY TOLD ME THAT THERE WASN'T A RECALL FOR THE PRIUS AND TRANSFERRED ME TO THE MAIN TOYOTA LINE TO ANSWER MY QUESTIONS, BUT THAT CALL ENDED DUE TO HIGH PHONE CALL VOLUME. *TR

EXPERIENCED EXACT SAME TEMPORARY LOSS OF BRAKING AFTER DRIVING OVER BUMPS, POT HOLE AS DESCRIBED IN YOUR INVESTIGATION. HAVE EXPERIENCED THIS PROBLEM REPEATEDLY SINCE FIRST DAYS OF OWNERSHIP. *TR

DRIVING OUR 2010 TOYOTA PRIUS OVER BUMPS AND POTHOLES THE CAR BRAKING SYSTEM IS NOT WORKING PROPERLY. IT DOESN'T STOP IMMEDIATELY AFTER THE BRAKES ARE PRESSED. WE HAVE BROUGHT THE CAR IN FOR SERVICE AND TOYOTA THEY SAY THE CAR IS FINE. *TR

ON TWO OCCASIONS MY 2010 TOYOTA PRIUS 3 BRAKES HAVE FAILED AS DESCRIBED IN RECENT NY TIMES ARTICLE. I WAS DRIVING ON ROUGH ROAD WITH POT HOLES AND MAN HOLE COVERS, SLIGHTLY WET PAVEMENT AND THERE WAS A MOMENTARY LOSS OF BRAKING (SORT OF LIKE THE CAR WAS HYDROPLANING). I PURCHASED MY PRIUS IN NOVEMBER 2009. *TR

BRAKES GRAB TOO QUICKLY, JOLTING THE CAR TO A STOP. *TR

I HAVE A NEW 2010 TOYOTA PRIUS, PURCHASED 15 JAN. 2010. I HAVE SINCE PUT 3,292 MILES ON THE VEHICLE ON A TRIP FROM WASHINGTON TO CALIFORNIA AND BACK, DURING WHICH CONDITIONS FROM MOUNTAINS, SNOW AND ICE, AND DRY FREEWAY CONDITIONS WERE ENCOUNTERED. THE RANDOM PROBLEM OCCURRED SEVERAL TIMES WHEN USING THE BRAKE PEDAL TO DISCONNECT THE CRUISE CONTROL TO SLOW DOWN. THE PROBLEM IS MOST PRONOUNCED WHEN THE POWER APPLIED TO THE VEHICLE IS INCREASING TO MAINTAIN SELECTED CRUISE CONTROL SPEED. WHEN THE BRAKE IS APPLIED IN THESE SITUATIONS, THE VEHICLE TRIES TO ACCELERATE FOR A SECOND OR SO, GIVING THE DRIVER THE FEELING OF NOT BEING IN CONTROL. THE PROBLEM IS MOST PRONOUNCED WHEN CLIMBING A STEEP (6% TO 8%) GRADE. IN THOSE CASES (2 TO 3 TIMES) THE POWER SURGE WAS PRONOUNCED AND SEEMED TO LAST FOR 2 TO 3 SECONDS WITH THE SMELL OF BURNING BRAKES AFTER THE ACCELERATION ENDED. ON THE FREEWAY, WHILE THE PROBLEM IS LESS SEVERE, THE DRIVER IS LEFT WITH AN UNCOMFORTABLE SITUATION IF COMING UP ON A SLOWER MOVING VEHICLE AS YOUR VEHICLE CONTINUES TO GAIN ON THE VEHICLE AHEAD EVEN THOUGH YOU ARE TRYING TO SLOW DOWN. THESE INCIDENTS OCCURRED OVER A PERIOD OF THREE WEEKS, SO THE DATE BELOW IS NOT ACCURATE. *TR

I RECENTLY PURCHASED TOYOTA PRIUS 2010 AND ALREADY HAVE AN ACCIDENT DUE TO FAULTY BRAKE SYSTEM. WHEN THE BRAKE IS APPLIED, THE CARE DOES NOT SLOW DOWN INSTANTLY BUT KIND OF ACCELERATES AND THE SLOWS DOWN WHICH IS A MAJOR SAFETY HAZARD. *TR

MY TOYOTA PRIUS HAS A PROBLEM WITH SUDDEN SHAKING WHEN LIGHTLY APPLYING THE BRAKES. THE PROBLEM IS INTERMITTENT. THE DEALER DOES NOT KNOW WHAT TO DO UNTIL TOYOTA GIVES CLEAR DIRECTION. *TR

TOYOTA PRIUS 2010 MODEL - BOUGHT JULY 2009 - PERIODICALLY (TAKEN PLACE OVER A PERIOD OF 6 MONTHS OR SO) WHEN PRESSING THE BRAKE PEDAL, THERE IS A SHORT PERIOD OF TIME WHEN IT IS APPARENT THAT NO BRAKING ACTION IS TAKING PLACE AND THAN ALL OF A SUDDEN YOU CAN TELL THAT THE BRAKING ACTION HAS TAKEN PLACE. IT IS SCARY WHEN THIS TAKES PLACE. I DO HAVE AN APPOINTMENT WITH THE DEALER THIS COMING WEEK. *TR

AROUND THE FIRST OF JANUARY, 2010, WE HAD TURNED INTO THE DRIVE OF OUR HOME IN GRENADA, MS. AS THE DRIVE CURVES IN FRONT OF THE HOUSE IT IS BORDERED BY A BRICK RETAINING WALL. WE WERE GOING SLOWLY AND INTENDED TO APPLY THE BRAKE. INSTEAD OF SLOWING THE 2010 PRIUS SPEED UP AND STRUCK THE WALL. THE RESULTING DAMAGE WAS BETWEEN $4500 AND $5000. I ASSUMED WE HAD MISTAKENLY USED THE ACCELERATOR INSTEAD OF THE BRAKE. I STILL BELIEVE THAT IS EXACTLY WHAT OCCURRED. HOWEVER, WITH THE ISSUES AROUND THE PRIUS, I WANTED TO REPORT THIS INCIDENT. THERE WAS NO INJURY AND THE CAR HAS BEEN REPAIRED WITH INSURANCE PROCEEDS. I'M HAPPY TO PROVIDE MORE INFORMATION IF YOU LIKE. *TR

WHILE DRIVING MY 2010 TOYOTA PRIUS I APPROACHED A RED LIGHT WITH TRAFFIC STOPPED IN FRONT OF ME AT THE LIGHT. IT HAD BEEN RAINING AND THE PAVEMENT WAS WET. I BEGAN TO GENTLY BRAKE TO STOP WELL BEHIND THE STOPPED TRAFFIC AT THE LIGHT. I PASSED OVER SOME ROUGH/BUMPY ROAD AND THE BRAKES FAILED FOR ABOUT 1 SECOND AND THE CAR SHOT FORWARD APPROXIMATELY 10 FEET. THE BRAKES THEN BEGAN WORKING AGAIN IN ABS MODE AND I WAS ABLE TO AVOID HITTING THE STOPPED TRAFFIC IN FRONT OF ME BY ONLY 12 TO 24 INCHES. THIS HAS HAPPENED A NUMBER OF TIMES SINCE PURCHASING THIS 2010 PRIUS IN NOVEMBER OF 2009. IT HAS HAPPENED 3 OR 4 TIMES IN THE 3 MONTHS I HAVE OWNED THE VEHICLE. THE LOSS OF BRAKING CAUSES A SEVERE SENSE OF PANIC AND DISTRESS AND THE VEHICLE DOES SHOOT FORWARD FOR THAT SECOND OR SO. AND IN THE CASE NOTED ABOVE CAME VERY CLOSE TO CAUSING AN ACCIDENT. IT IS ONLY TIME BEFORE IT WILL CAUSE AN ACCIDENT AND HARM TO ME AND/OR OTHERS. TOYOTA HAS NOT OFFERED ANY REMEDY. THEY KNOW THE PROBLEM EXISTS AND HAVE KNOWN IT FOR QUITE SOME TIME. COMMUNICATION FROM TOYOTA ABOUT THE PROBLEM HAS BEEN ALMOST NON-EXISTENT. *TR

MY 2010 PRIUS HAS SEEMED TO 'GO AIRBORNE" WHEN I HIT A CERTAIN SPOT ON A LOCAL FREEWAY EXIT RAMP. WHEN I APPLY MY BRAKES AT THE END OF THE RAMP, THE BRAKES SEEM TO MISS AS THERE IS A DEPRESSION IN THE PAVEMENT. IT HAS HAPPENED MORE THAN ONCE IN THAT SPOT. I KNOW IT IS THE CAR BECAUSE WHEN I DROVE MY SATURN OVER THAT SPOT IT NEVER HAPPENED IN THREE YEARS OF EXITING THERE. I CALLED MY DEALERSHIP TWO WEEKS AGO AND THEY HAD NOT HEARD ABOUT THIS PROBLEM. I CALLED AGAIN THIS WEEK AND THEY WERE VERY AWARE OF THIS. I DID TELL THEM THAT THIS WAS A POTENTIAL HAZARD AND HOPED THAT ALL PRIUS 2010 CARS WILL BE FIXED. TO BE FAIR, I DID NOT ASK FOR THEM TO REPAIR MY CAR SINCE I HAD FIGURED OUT HOW TO PREVENT THE SKIP (BRAKING EARLIER, SLOWING MORE). BUT I THINK THIS SHOULD BE PART OF A RECALL BECAUSE THIS DEFECT CAN HAPPEN QUITE OUT OF THE BLUE, WHICH COULD CAUSE AN ACCIDENT DEPENDING ON ROAD CONDITIONS. I EXPERIENCED A SIMILAR INCIDENT LAST MONTH ON A SLIPPERY ROAD (ICE) BUT DIDN'T MAKE THE CONNECTION. *TR

2010 PRIUS BRAKING PROBLEM. WE THOUGHT IS WAS US OR THE CAR. WE BOUGHT IN AUGUST 2009. MY WIFE ALMOST HIT ANOTHER CAR ON 2/4. SLOW SPEED, BUMPS, THE CAR DID NOT APPEAR TO STOP WHILE BRAKING, THEN IT FINALLY STOPPED. I TOLD MY WIFE OF PROBLEMS EARLIER, BUT THEY WERE PERIODIC. *TR

ONE OCCASION OF FAILURE OF BRAKES FOR 1-2 SECONDS ON 2010 PRIUS (OVER ROUGH ROAD). *TR

THIS PROBLEM SEEMS TO OCCUR WHEN I AM JUST BEGINNING TO BRAKE OR IN THE MIDDLE OF BRAKING, IF I GO OVER ANY UNEVEN TERRAIN (I.E. POTHOLE, DIPS, ETC.), THE BRAKING SYSTEM FEELS LIKE IT IS GIVING. IT GENERALLY ONLY LASTS FOR A SECOND OR SO, BUT IT IS UNNERVING. I DO FEEL THE CAR LUNGE FORWARD AT THIS POINT, AND FEEL THAT I HAVE NO CONTROL OVER MY CAR. I DRIVE IN THE CITY ON A DAILY BASIS, AND THAT WAS ONE OF THE MAIN REASONS FOR ME PURCHASING THIS CAR. IT IS NOT A COMFORTABLE FEELING, AND IT IS TERRIFYING TO MY PASSENGERS. WHEN I CONTACTED TOYOTA, THEY WERE VERY CONDESCENDING. MADE IT SEEM LIKE IT IS JUST BECAUSE THE AUTOMOBILE IS SO ADVANCED AND TECHNICAL, AND THAT IS SUPPOSED TO HAPPEN. HOWEVER, MY 2 BROTHERS BOTH HAVE OLDER PRIUSES, AND NEITHER HAVE EXPERIENCED THIS. *TR

2010 TOYOTA PRIUS LOSS OF BRAKES - THIS HAS HAPPENED FOUR TIMES IN THE SEVEN MONTHS THAT I HAVE OWNED THIS VEHICLE. ALL FOUR TIMES WERE WHEN THE VEHICLE WAS ON ICE OR HARD PACKED SNOW. DETAILS; WHEN COMING TO A STOP AT RELATIVELY LOW SPEED (APPROX. 10MPH) ON EITHER ICE OR HARD PACKED SNOW THE VEHICLE WILL LOSE ALL BRAKING FOR ABOUT 5 TO 10 FEET. THE FIRST SEVERAL TIMES THIS HAPPEN I THOUGHT THAT I HIT A PATCH OF BLACK ICE BUT DIDN'T UNDERSTAND WHY THE ANTI-LOCK BRAKES DID NOT CHATTER. *TR

IN JUNE I PURCHASED A 2010 TOYOTA PRIUS. I LIVE IN A COLD WINTER CLIMATE AND HAVE NOTICED THAT THE CAR BRAKES SEEM TO DISENGAGE FOR SHORT PERIODS OF TIME, PARTICULARLY AS I COME TO A STOP ON A SNOWY/ICE RUTTED ROAD, OR AM GOING OVER A BUMPY SURFACE. IF I LEAVE MY FOOT ON THE BRAKE, IT WILL REINGAGE QUICKLY. IN OTHER WORDS, I PUT ON THE BRAKE, AND THE CAR STARTS TO RESPOND BUT THEN "JUMPS AHEAD" AS IF IT'S SLIDING ON GLARE ICE BEFORE COMING TO A COMPLETE STOP. THE PROBLEM IS INTERMITTENT, DEPENDING UPON THE CONDITION OF THE ROAD AT THE TIME. I HAVE REPORTED THE PROBLEM TO THE DEALERSHIP. *TR

TOYOTA 2010 PRIUS INTERMITTENT BRAKE FAILURE WHEN BRAKING ON ROUGH PAVEMENT- I PURCHASED A NEW 2010 TOYOTA PRIUS ON JUNE 30, 2009 AND HAVE APPROXIMATELY 6400 MILES ON THE VEHICLE. WE EXPERIENCE TWO ISSUES WHEN BRAKING ON ROUGH PAVEMENT. FIRST IS THAT THE BRAKES SEEM TO FAIL WHEN APPLIED IN NORMAL NON PANIC STOPPING IF THERE IS WET OR ROUGH PAVEMENT. SECOND WHEN THE FIRST SYMPTOM OCCURS IT IS ALSO ACCOMPANIED BY WHAT FEELS LIKE AN INCREASE IN TORQUE AT THE FRONT WHEELS SO THAT NOT ONLY DO THE BRAKES FEEL LIKE THEY ARE FAILING THE CAR LURCHES FORWARD FROM THE ADDED THRUST. *TR

TOYOTA PRIUS 2010 PURCHASED JULY 2009. THIS VEHICLE HAS THE BRAKING PROBLEM WHICH IS DESCRIBED IN THE MEDIA. THE BRAKE "INTERMITTENT RELEASE" ON UNEVEN ROAD SURFACE IS REPEATABLE AND HAS BEEN SYMPTOMATIC SINCE NEW. *TR

VEHICLE - TOYOTA 2010 PRIUS. THIS PARTICULAR PROBLEM IS ONGOING YET INTERMITTENT. DESCRIPTION - THE BRAKES GRAB UNEXPECTEDLY. HAPPENS AFTER VEHICLE HAS BEEN DRIVEN, PARKED AND THEN RE-STARTED. WE NEVER KNOW WHEN IT IS GOING TO HAPPEN. WE HAVE TO COMPLETELY STOP THE VEHICLE (NOT TURNING IT OFF) AND BEGIN AGAIN. THEN THE PROBLEM APPEARS TO GO AWAY. THE DESCRIPTION OF THE BRAKES GRABBING IS AS FOLLOWS: WHEN THE BRAKE PEDAL IS PRESSED EVER SO SLIGHTLY, THEY GRAB AND THE CAR COMES TO A JERKY HALT. WE TRY IT AGAIN AND IT REPEATS. THIS IS NOT NORMAL VEHICLE BEHAVIOR. I CANNOT ANSWER INCIDENT DATE SINCE THE PROBLEM IS ONGOING AND INTERMITTENT. I WILL INSERT THE APPROXIMATE FIST INCIDENT. *TR

TOYOTA PRIUS 2010: I HAVE EXPERIENCED MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING DOWN THE HILL AND MADE A RIGHT TURN. THIS HAS HAPPENED TWICE. *TR

UPON ENTERING THE ROAD TO MY DRIVEWAY THERE ARE A SMALL SERIES OF DIPS AND BUMPS OR SHORT SEQUENCE OF SMALL POTHOLES FROM THE RAIN. WHEN I LIGHTLY APPLY THE BRAKE TO SLOW DOWN THE PEDAL SEEMS TO HAVE "NO BRAKING AFFECT" WHEN I GO DOWN INTO AN COME OUT OF THE FIRST OF THE SERIES OF DIPS. THE BRAKES THEN RETURN TO NORMAL IN MY DRIVE WAY. WHAT I HAVE BEEN DOING IS AVOIDING THE DIPS AND THEREBY AVOIDING THE EERIE FEELING THAT MY BRAKES HAVE FAILED. *TR

ON DECEMBER 29, 2009 WE PURCHASED A 2010 TOYOTA PRIUS. WITHIN A FEW DAYS WE EXPERIENCED BRAKE PROBLEMS WHILE BACKING UP AND APPLYING THE BRAKES LIGHTLY. THE PRIUS STOPPED ABRUPTLY MANY TIMES BEFORE WE WERE IN A POSITION TO MOVE FORWARD. THIS HAS HAPPENED ON A NUMBER OF TIMES; HOWEVER, THIS BEHAVIOR IS INTERMITTENT. AND ON ANOTHER OCCASION THE CAR VEERED TO THE RIGHT WHILE TRAVELING FORWARD AND APPLYING THE BRAKES IN AN EMERGENCY SITUATION. *TR

I OWN A 2010 PRIUS PURCHASED AROUND SEPT. 2009. A FEW WEEKS AFTER WE GOT THE VEHICLE, MY WIFE AND I INDEPENDENTLY BOTH EXPERIENCED A SUDDEN ACCELERATION WHEN THE CAR WENT OVER A BUMP. THIS HAS OCCURRED ABOUT A TOTAL OF 4 TIMES. MY FOOT WAS NOT ON THE ACCELERATOR AT THE TIME THIS OCCURRED. STEPPING ON THE BRAKE DID SLOW THE VEHICLE DOWN. THE LAST TIME I EXPERIENCED THIS WAS 2-3 WEEKS AGO. I DID ASK THE DEALER SHORTLY AFTER THE INITIAL INCIDENT IF HE HAD HEARD OF THIS PROBLEM AND HE SAID NO. I HAVE NOT SINCE BROUGHT THE CAR BACK TO THE DEALER. WE HAVE NOTICED THIS ONLY WHEN THE CAR GOES OVER A BUMP.*TR

STARTED UP MORNING AFTER RAINY DAY, DROVE DOWN HILL TO STOP SIGN. APPROACHING STOP SIGN I APPLIED BRAKES AND NOTICED BRAKES DIDN'T IMMEDIATELY SLOW ME DOWN. ONLY AFTER FLOORING THE PEDAL AND FEELING A METAL ON METAL TYPE REACTION DID I COME TO A STOP. THIS PROBLEM HAS NOT REPEATED ITSELF. *TR

I HAVE HAD A 2010 TOYOTA PRIUS SINCE SEPTEMBER 2009. I BOUGHT IT FROM A DEALER-TOYOTA OF LAKE CITY, SEATTLE, WA. I HAVE BEEN EXPERIENCING THE FOLLOWING PROBLEM: A MOMENTARY REDUCTION IN BRAKING PERFORMANCE WHILE TRAVELING OVER AN UNEVEN ROAD SURFACE OR BUMPS AND APPLYING THE BREAKS. IT FEELS LIKE THE BRAKES SLIP AND THE CAR JERKS FORWARD WHEN THE BRAKES ARE APPLIED WHILE TRAVELING (ESPECIALLY DOWNHILL) ON AN UNEVEN ROAD SURFACE OR BUMPS. THIS PROBLEM OCCURS EVERY TIME/DAY I DRIVE ON AN UNEVEN ROAD SURFACE OR BUMPS, AND TRY TO APPLY THE BRAKES. NOTHING HAS BEEN DONE TO CORRECT THE FAILURE AS NO RECALL HAS BEEN ISSUED YET. DEALER NOTIFIED OF PROBLEM. *TR

I WAS DRIVING MY 2010 PRIUS (BUILT BEFORE JANUARY, 2010) ON ICY CONDITIONS. I COASTED TO A STOP SIGN AND APPLIED THE BRAKES. THE CAR SEEMED TO IGNORE MY BRAKING AND CONTINUED THROUGH THE STOP SIGN 2-3 FEET. I ATTRIBUTED THE PROBLEM TO THE WEATHER CONDITIONS AND PROCEEDED WITH CAUTION. AT THE NEXT STOP SIGN, I WAS ESPECIALLY CAREFUL, BUT WHEN I APPLIED THE BRAKES, THE CAR SEEMED TO SURGE FORWARD FOR 1-2 SECONDS, ENOUGH TIME TO PUT ME IN THE PATH OF AN ONCOMING PICK-UP TRUCK. NOBODY WAS HURT, BUT THE DAMAGE WILL COME TO ABOUT $11,000. AFTER HEARING ABOUT THE PRIUS' BRAKE PROBLEMS, I REALIZED THAT THE LACK OF BRAKE ACTION THAT I EXPERIENCED IS VERY SIMILAR TO OTHER COMPLAINTS ABOUT PRIUS' BUILT PRIOR TO TOYOTA'S JANUARY PROGRAMMING FIX. I AM UPSET THAT TOYOTA KNEW ABOUT THIS PROBLEM, BUT FAILED TO TELL ME ABOUT IT. AS A RESULT, I WILL END UP WITH A LESS VALUABLE REPAIRED VEHICLE WITH A KNOWN BRAKE DEFECT AND HIGHER INSURANCE RATES WHICH WILL PLAGUE MY WALLET FOR YEARS TO COME. *TR

UPON BRAKING APPROACHING A STOPLIGHT, MY 2010 TOYOTA PRIUS HIT A POTHOLE AND SUDDENLY JERKED FORWARD, THEN RETURNED TO SLOWING. I KEPT MY FOOT ON THE BRAKE AND THE CAR STOPPED NORMALLY. *TR

I OWN A 2010 TOYOTA PRIUS, PURCHASED IN NOVEMBER, 2009. TWICE, I HAVE BEEN GOING OVER A SMALL BUMP IN THE ROAD AND THE CAR HAS ACCELERATED SUDDENLY INSTEAD OF BRAKING. THIS HAPPENED BOTH IN JANUARY AT THE SAME INTERSECTION -- AT THE INTERSECTION OF HAMPDEN AND MONACO IN DENVER, COLORADO. *TR

I ATTEMPTED TO BRING MY 2010 PRIUS TO A STOP ON A DIRT ROAD LEADING TO AN ASPHALT SURFACE THAT WAS COVERED WITH A RECENT SNOWFALL OF ABOUT 2 INCHES. THE BRAKES DID NOT GRAB FOR ABOUT 3 SECONDS DURING WHICH I ATTEMPTED TO PUMP THE BRAKES. THE CAR HAD 4 SNOW TIRES MOUNTED ON IT WHICH USUALLY GRAB RIGHT AWAY. *TR

I WAS COMING UP TO AN INTERSECTION WITH A STOPLIGHT. THE LIGHT TURNED RED. I WAS GOING OVER A MANHOLE AS I HIT THE BRAKES. MY BRAKES DID NOT WORK AND IN FACT, MY CAR LURCHED FORWARD. I STEPPED HARD ON THE BRAKE AND EVENTUALLY STOPPED. LUCKILY, THE CAR AHEAD OF ME WAS FAR ENOUGH AWAY OR I WOULD HAVE REAR-ENDED IT. ANOTHER INCIDENT HAPPENED A FEW DAYS AFTER A SNOWFALL. THE END OF MY STREET HAD SOME HARD, PACKED SNOW THAT THE PLOW LEFT BEHIND. AS I CAME UP TO THE STOP SIGN, MY BRAKES DID NOT WORK AND I ENDED UP IN THE CROSS STREET. I WAS ONLY GOING ABOUT 10-15 MPH AT THE TIME THAT I BRAKED. THIS INCIDENT HAPPENED IN DECEMBER 2009, THE OTHER IN JANUARY 2010. NOTHING HAS BEEN DONE TO CORRECT OR REPAIR THE CAR. *TR

2010 PRIUS IV - BRAKING IS DELAYED IN WET CONDITIONS AND WHEN I DRIVE OVER A BUMP OR POTHOLE. HAVE TO KEEP THE BRAKE PEDAL PRESSED AND IT FEELS AND SOUNDS LIKE THE ENGINE ACCELERATES BEFORE THE BRAKE COME ON. IT LASTS FOR FEW SECONDS AND DOES NOT HAPPEN ALWAYS. *TR

ON SEVERAL OCCASIONS, MY 2010 TOYOTA PRIUS HAS LURCHED AHEAD AFTER HITTING A POTHOLE, AS DESCRIBED IN THE FEB. 4 NEW YORK TIMES ARTICLE. NO CONTACT OR PROPERTY DAMAGE HAS OCCURRED. *TR

AS I SLOW DOWN IN MY 2010 TOYOTA PRIUS, IF THE CAR GOES OVER ANY BUMPS, I FEEL AN "ACCELERATION" (ACTUALLY A SUDDEN STOP IN DECELERATION) AS I AM APPLYING THE BRAKES. I WENT TO MY TOYOTA DEALER AND THEY ACKNOWLEDGED THAT THEY'D HEARD OF THE ISSUE, BUT DENIED IT WAS A PROBLEM. *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

I HAVE HAD A BRIEF FAILURE OF THE BRAKES ON MY 2010 PRIUS IV. I WAS DRIVING IN TOWN COMING BACK FROM THE SCHOOL WHERE I TEACH. I SLOWED AS I CAME UP ON ANOTHER VEHICLE STOPPED AT A STOPLIGHT. ALTHOUGH I HAD MY FOOT ON THE BRAKE, IT DID NOT START TO BRAKE FOR A COUPLE OF SECONDS. I NARROWLY AVOIDED AN ACCIDENT. *TR

TOYOTA PRIUS 2010. ON THREE OCCASIONS ON ICE AND/OR SNOWY ROADS THE BRAKES FAILED TO STOP THE CAR SAFELY. ON TWO OCCASIONS THE CAR CAME DOWN THE BRICK STREET AND INTO THE CROSS STREET. FORTUNATELY NO ACCIDENT OCCURRED. FIRST TIME IN DEC. 2009, TWICE IN JAN. 2010. *TR

I WAS APPROACHING A TRAFFIC SIGNAL, HIT A SMALL POT HOLE, AND APPLIED THE BRAKES ON MY 2010 TOYOTA PRIUS. THE PEDAL WENT ALL THE WAY TO THE FLOOR AND THE CAR DID NOT SLOW. I RELEASED THE PEDAL AND STEPPED ON IT A SECOND TIME AND THIS TIME THE BRAKES WORKED. *TR

MY 2010 PRIUS HESITATED TO BRAKE PROPERLY/CAUSED A DELAY AT 10MPH ON THE FREEWAY, AS A RESULT MY LEFT FENDER MADE CONTACT WITH THE VEHICLE IN FRONT OF ME. AS RESULT, MY INSURANCE INCREASED, I HAD TO PAY $500 DEDUCTIBLE TO REPAIR MY BUMPER. ALSO THE BACK BRAKES HAVE SQUEAKED GOING IN REVERSE SINCE PURCHASE IN NOVEMBER 2009. *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 OWN 2010 TOYOTA PRIUS PURCHASED IN JANUARY 2010. TWICE I HAVE ENCOUNTERED BRAKING PROBLEM. IN BRAKING FROM 40 MILES AN HOUR FOR TRAFFIC CONGESTION, I HAD TO RESORT TO LAST SECOND ADDITIONAL FOOT PRESSURE TO AVOID HITTING THE CAR IN FRONT OF ME. UNLIKE THE COMPLAINS I HAVE READ IN THE MEDIA, MY PROBLEM DID NOT OCCUR DUE TO SLIPPERY ROAD OR ANY KIND OF BUMP. SIMPLY PUT, STOPPING REQUIRED UNUSUAL FOOT PRESSURE THAT I HAVE NEVER ENCOUNTERED IN ANY PREVIOUS VEHICLE. *TR
