2010 Toyota Prius complaints

I WANT TO COMPLAIN ABOUT THE BRAKING PROBLEM WITH MY TOYOTA PRIUS 2010 WHICH I PURCHASED IN NOVEMBER OF 2009. ON SEVERAL OCCASIONS, ABOUT 4 OR 5, THE BRAKES DON'T WORK WHEN GOING OVER A BUMP HITTING A POTHOLE AND THE CAR SLIDES FORWARD. THIS HAS HAPPENED WHILE SLOWING DOWN AT LIGHTS AND INTERSECTIONS. *TR

AT 8:00 AM THIS MORNING, I WAS DRIVING THROUGH A STREET AT A SPEED OF 20 MILES TO 30 MILES PER HOUR. SUDDENLY, THE CAR JUMPED A LITTLE PROBABLY HIT A SMALL POTHOLES OR BUMPS. I FELT LIKE THE CAR SURGED FORWARD OR MAY BE THE BRAKE DIDN'T RESPOND IMMEDIATELY. FORTUNATELY, NO OTHER CAR RIGHT IN FRONT OF ME AND THE CAR SPEED IS NOT VERY FAST. I WAS ABLE TO BRAKE IT AND SLOW DOWN. I HAVE CALLED THE DEALER AND THE SERVICE REPRESENTATIVE DOESN'T THINK IT IS A PROBLEM. LATER, I ALSO SENT A FAX TO TOYOTA US HEADQUARTER ASKING FOR HELP. *TR

2010 TOYOTA PRIUS PURCHASED ON JULY 31, 2009. BETWEEN 10 AND 12 TIMES SINCE PURCHASE DATE, WHEN APPLYING THE BRAKES SIMULTANEOUSLY WITH DRIVING OVER A BUMP OR ROUGH SECTION OF ROAD, THE CAR FELT AS THOUGH IT WAS ACCELERATING RATHER THAN BRAKING. THIS LASTED FOR ONE SECOND OR LESS BUT WAS FRIGHTENING. THE FIRST TIME I THOUGHT IT WAS MY IMAGINATION BUT IT OCCURRED ANOTHER 10 TIMES OR SO. IT ALWAYS OCCURS WHEN GOING OVER A BUMP. AS FAR AS I CAN RECALL, THE PAVEMENT WAS ALWAYS DRY. FORTUNATELY, THERE WAS NO ACCIDENT IN ANY OF THESE OCCURRENCES. *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

BRAKES SPORADICALLY GRAB AND MAKE SMOOTH BRAKING IMPOSSIBLE. THESE ARE UNEXPECTED AND INTERMITTENT. IT OCCURS MAYBE TEN PERCENT OF MY TRIPS. CONSEQUENCES ARE JOLTING STOP. NOTHING ALLEGEDLY CAN BE DONE TO CORRECT THE FAILURES. *TR

I HAVE A 2010 TOYOTA PRIUS. ON A DAILY BASIS I DRIVE OVER TWO SEPARATE SPEED BUMPS ON THE STEEP DOWNHILL-INCLINE ENTRANCE TO MY OFFICE PARKING GARAGE, AT A LOW SPEED (ALWAYS LESS THAN 10 MPH). UPON GOING OVER EACH BUMP, MY BRAKES (WHICH ARE ENGAGED DUE TO THE STEEP DOWNHILL INCLINE) DISENGAGE BRIEFLY AND THEN RE-ENGAGE. SOMETIMES THE BRAKES ALSO MOMENTARILY DISENGAGE WHEN I AM CONTINUING DOWN THE RAMP IN THE PARKING GARAGE, EVEN IN THE ABSENCE OF A SPEED BUMP. THIS SEEMS TO HAPPEN MOST OFTEN WHEN I AM TURNING. EACH TIME THE BRAKES DISENGAGE, THE CAR SLIPS AND I FEEL IT IS NOT UNDER CONTROL. I HAVE TRIED TO AVOID THESE SYMPTOMS BY KEEPING MY SPEED EXTREMELY LOW IN THE PARKING GARAGE (5 MPH), BUT THAT ONLY WORKS SOMETIMES. THE "DATE OF INCIDENT" IS REALLY ON A DAILY BASIS EVERY DAY I DRIVE INTO WORK. THIS SYMPTOM HAS OCCURRED CONSISTENTLY SINCE I PURCHASED THE CAR IN JUNE, 2009 AND CONTINUES TO THIS DAY. THE BRAKE SYSTEM I AM REFERRING TO IS THE BRAKES THAT ARE ACTIVATED WHEN I DEPRESS THE BRAKE PEDAL WHILE DRIVING. *TR

I PURCHASED A BRAND NEW 2010 TOYOTA PRIUS V ON SEPTEMBER 24, 2009. IT PERFORMED BEAUTIFULLY, AND WAS A REAL PLEASURE TO DRIVE. HOWEVER, A MONTH OR SO LATER, WITH THE CAR IN REVERSE, I STARTED BACKING OUT OF A PARKING PLACE AND IMMEDIATELY NOTICED AN UNUSUALLY INTENSE "REVVING" OF THE ENGINE. STARTLED, I IMMEDIATELY PRESSED ON THE FOOT BRAKE, RELEASING IT IN LITTLE STEPS UNTIL THE CAR WAS "INCHED" OUT OF THE PARKING PLACE. I THEN SHIFTED THE LEVER INTO "DRIVE" AND PROCEEDED ON MY WAY QUITE NORMALLY WITHOUT ANY FURTHER PROBLEM WHATSOEVER. IN THE ENSUING MONTHS, THIS STRANGE PHENOMENON HAS ONLY REPEATED ITSELF TWO MORE TIMES OUT OF HUNDREDS OF BACKOUTS FROM PARKING SLOTS. THERE HAS BEEN NO OTHER CIRCUMSTANCE IN WHICH THIS SEVERE " REVVING" HAS RE-OCCURRED. IN THE AFOREMENTIONED THREE CASES, I HAD NO RECOLLECTION WHATSOEVER OF PRESSING THE FOOT THROTTLE, AND THEREFORE HAVE PRESUMED THAT THE PROBLEM IS IN THE ELECTRONICS OR SOFTWARE, RATHER THAN IN THE FLOOR THROTTLE MECHANICS. IN EVERY OTHER RESPECT SO FAR, MY 2010 TOYOTA PRIUS V HAS PERFORMED PERFECTLY. *TR

ON FEB. 3, 2010 THE BRAKES IN MY 2010 PRIUS FAILED ON SUDDEN APPLICATION AND THE PEDAL WENT ALL THE WAY TO THE FLOOR. I SWERVED RIGHT TO AN OPEN LANE, REAPPLIED THE BRAKES AND THIS SECOND APPLICATION WAS SUCCESSFUL AND SLOWED THE CAR. EVENT TOOK PLACE GOING 47 MPH ON CREST OF HILL WHEN CAR IN FRONT BRAKED SUDDENLY, AND I WENT FROM ACCELERATION TO SUDDEN BRAKING. PRIOR TO THIS EXPERIENCE I HAD MADE TWO COMPLAINTS TO MY LOCAL DEALER BECAUSE THE BRAKES OCCASIONALLY GRABBED VIOLENTLY WHEN I WAS BACKING OUT OF A PARKING SPACE. THE DEALER COULD NOT REPLICATE THIS ACTION, SO I JUST PUT UP WITH IT. THE DEALER NOW HAS MY CAR AND HAS PROVIDED A RENTAL CAR AT MY REQUEST. *TR

WHEN TRAVELING FORWARD OVER UNEVEN, BUMPY PAVEMENT, POT HOLES, OR SPEED BUMPS AND APPLYING THE BRAKES AT THE SAME TIME THE CAR SUDDENLY ACCELERATES VERY STRONGLY. THE ACCELERATION HAPPENS EVEN THOUGH YOU ARE PRESSING ON THE BRAKE PEDAL AND YOUR FOOT IS COMPLETELY OFF THE ACCELERATOR. THE SUDDEN ACCELERATION IS SO STRONG THAT IT NEARLY JERKS THE STEERING WHEEL OUT OF YOUR HAND. THIS INCIDENT HAS HAPPENED ONCE WHEN MY WIFE WAS DRIVING THE CAR AND THREE TIMES WHEN I HAVE BEEN DRIVING. IT ALMOST FEELS LIKE THE BRAKES STOP WORKING FOR A SECOND OR TWO AND THE CAR ACCELERATES BY ITSELF. WHEN IT HAPPENS IT IS QUITE STARTLING. I TOOK THE CAR TO THE DEALER AND THEY SAID NOTHING WAS WRONG WITH IT. THIS IS A SERIOUS SAFETY ISSUE THAT NEEDS TO BE LOOKED INTO. *TR

MY 2010 PRIUS HAS TROUBLE BRAKING WHEN I'M TRAVELING AT SLOW SPEEDS OVER UNEVEN OR SLIPPERY SURFACES. IT'S AS IF THE BRAKES LOSE TRACTION/SLIP. I FIRST REPORTED THIS PROBLEM TO TOYOTA IN OCTOBER 2009. I SENT EMAILS AND PLACED PHONE CALLS AND BROUGHT IT TO THE DEALERSHIP REPEATEDLY. THEY SAY THEY WERE UNABLE TO REPLICATE THE PROBLEM AND CAN'T FIX IT TILL THEY REPLICATE IT. THEY HAVE NO SOLUTIONS FOR ME. I CALLED TOYOTA TODAY AND THEY SAID THEY DID NOT REFER MY COMPLAINT TO NHTSA...EVEN THOUGH I FILED IT WITH TOYOTA MONTHS AGO. THEY SAY ITS NOT THEIR RESPONSIBILITY TO SHARE MY COMPLAINT WITH THE GOVERNMENT. *TR

2010 TOYOTA PRIUS - PURCHASED IN NOV 2009. CAR JUMPS FORWARD WHEN APPLYING BRAKE. *TR

WE HAVE A NEW 2010 TOYOTA PRIUS TYPE IV THAT MY WIFE DRIVES. SEVERAL TIMES NOW SHE HAS EXPERIENCED PROBLEMS WITH THE BRAKING SYSTEM; WHEN SHE APPLIED THE BRAKES THE CAR LUNGED FORWARD AND THEN SHE HAD TO APPLY THE BRAKES REALLY HARD IN ORDER TO GET IT TO STOP. THIS OCCURRED SEVERAL TIME UPON HITTING A BUMP, BUT IT HAS ALSO OCCURRED ON A SMOOTH SURFACE ROAD. WE OBTAINED THIS NEW CAR IN SEPTEMBER 2009; SO THE FREQUENCY OF THIS PROBLEM IS PRETTY HIGH. WE UNDERSTAND THAT OTHERS ARE EXPERIENCING THIS SAME PROBLEM... WE WOULD LIKE TO CONFIRM AND COMPLAIN THAT WE TOO ARE EXPERIENCING THESE SAME PROBLEM WITH OUR PRIUS. WE HAVE CALLED THE LOCAL CAR DEALER WHERE WE PURCHASED THE VEHICLE, THEY ARE UNAWARE OF THIS PROBLEM AND OFFERED TO DO NOTING ABOUT IT. WE ALSO TRIED TO CALL THE TOYOTA EXPERIENCE CENTER BUT THE 800 NUMBER WAS OVER RUN WITH CALLS AND STATED THAT THEY COULD NOT PROCESS OUR CALL DUE TO HIGH CALL VOLUME. AT THIS POINT I AM VERY CONCERNED FOR THE SAFETY OF THOSE IN THE CAR AND THOSE WHO MAY BE STRUCK SHOULD WE EXPERIENCE THIS PROBLEM AT A CRITICAL MOMENT IN STOPPING THE VEHICLE. *TR

I OWN A 2010 TOYOTA PRIUS, PURCHASED IN OCTOBER OF 2009. I CONTACTED THE DEALER ABOUT SLIPPAGE WHEN BRAKING AND THEY WERE NOT HELPFUL. WHEN THE BRAKES ARE APPLIED, THE CAR DOES NOT STOP BUT FEELS LIKE IT IS SLIPPING AND YOU NEED TO REAPPLY THE BRAKES. I CONTACTED TOYOTA ABOUT THIS PROBLEM AND THEY DID NOT RESPOND. I HAVE NOW RECONTACTED THE DEALER AND THEY TOLD ME TO WAIT TO HEAR BACK FROM THEM. THEY HAVE NOT OFFERED TO LOAN ME A CAR UNTIL THIS PROBLEM IS RESOLVED. I AM DEEPLY DISAPPOINTED BY TOYOTA AND THE DEALERSHIP. *TR

I HAVE A 2010 PRIUS, WHICH HAS EXPERIENCED THE BRAKE DELAY PROBLEM THAT I READ ABOUT IN THE NEWS TODAY. IT HAS HAPPENED APPROXIMATELY 3 TIMES SINCE I PURCHASED THE CAR IN NOVEMBER 2009. I PRESSED ON THE BRAKE, AND THE CAR DID NOT SLOW IMMEDIATELY. EACH TIME THERE WAS A MOMENTARY DELAY, WHICH FRIGHTENED ME. *TR

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

WHILE DRIVING MY 2010 TOYOTA PRIUS, I NOTICE THAT AT TIMES THE CAR FAILS TO BRAKE ADEQUATELY. THIS HAPPENS WHEN BRAKING OVER UNEVEN PAVEMENT. THE FEELING IS AS IF THE CAR SPEEDS UP A LITTLE. IT'S DISCONCERTING. *TR

CONFIRMATION OF BRAKE ISSUE WITH PRIUS. CAR BRIEFLY ACCELERATES ON ROUGH PATCHES OR GOING OVER POTHOLES WHEN USING BRAKE. NO ACCIDENTS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE ENGAGING THE BRAKE PEDAL DRIVING APPROXIMATELY 20 MPH OVER A POTHOLE, THE BRAKES TEMPORARILY FAILED TO FUNCTION. THE FAILURE OCCURRED WHENEVER HE DROVE OVER ROUGH ROAD SURFACES. THE DEALER STATED THAT WHEN A FIX BECOMES AVAILABLE THEY WOULD NOTIFY HIM. THE MANUFACTURER WAS NOT NOTIFIED. THE CURRENT MILEAGE WAS APPROXIMATELY 4,000. THE FAILURE MILEAGE WAS APPROXIMATELY 2,500.

BRIEF BRAKING INTERRUPTION ON WET, UNEVEN PAVEMENT. 5 - 6 INCIDENTS FROM NOV THROUGH JAN - 2010 PRIUS BOUGHT AT THE END OF OCT 2009. *TR

I LIKE MANY OTHERS HAVE HAD SKIDDING AND NON-RESPONSIVENESS WHEN I HIT THE BRAKES ON THE 2010 PRIUS. *TR

I CURRENTLY OWN A 2010 TOYOTA PRIUS AND OVER THE PAST FEW MONTH I'VE NOTICED A MOMENTARY LOSS IN MY BRAKING WHEN TURNING CORNERS OR COMING TO A STOP. I'M ALITTLE CONCERN THAT THIS MIGHT BE A DEGENERATIVE ISSUE THAT MAY CAUSE A SERIOUS ACCIDENT AT HIGH SPEEDS. *TR

I HAVE NOTICED AN ISSUE WITH THE BRAKES IN MY 2010 PRIUS (IV) PURCHASED IN LATE AUGUST 2009 FROM WELLESLEY TOYOTA IN WELLESLEY, MA. I HAVE NOTICED AN ODD PULSING IN THE BRAKES, MUCH LIKE THE FEELING OF ALB SYSTEM KICKING IN. THE CAR SEEMS TO CONTINUE MOVING RIGHT THROUGH MY BRAKING. I SOMETIMES HAVE TO THEN SLAM THE BRAKES TO MAKE THE CAR STOP. THIS IS USUALLY TAKING PLACE AS I AM SLOWING TO A STOP SIGN OR LIGHT -- AND FREQUENTLY WHEN I'M GOING DOWNHILL. I HAD THOUGHT IT HAD SOMETHING TO DO WITH THE SWITCH BETWEEN GAS & ELECTRIC POWERING BUT I CAN'T BE SURE OF THAT. *TR

MY 2010 PRIUS WON'T STOP ON ROUGH OR ICED UP ROADS. *TR

MY 2010 PRIUS, WHICH WAS PURCHASED IN MAY HAS HAD THE VERY BRAKE ISSUES THAT ARE BEING REPORTED. WHEN A BUMP IS HIT, THE CAR JERKS FORWARD QUITE UNEXPECTEDLY WHEN THE BRAKES ARE APPLIED. I THOUGHT IT WAS JUST MY IMAGINATION OR THAT I HIT A SLICK SPOT, BUT IT HAS HAPPENED MANY TIMES. THE FACT THAT TOYOTA KNEW ABOUT THIS AND HID IT FROM THE FIRST PRIUS OWNERS IS UNBELIEVABLE. SINCE THEY HAVE BEEN FIXING IT ON NEWER MODELS AND DID NOT TELL OWNERS OF THE FIRST ONES OFF THE PRODUCTION LINE T, I THINK A CLASS ACTION LAW SUIT SHOULD BE UNDERTAKEN. I AM VERY ANGRY AND WOULD LIKE SOME MECHANISMS FOR GETTING RID OF THIS CAR, GIVEN TOYOTA'S DECEPTION. *TR

2010 TOYOTA PRIUS LOOSING BRAKING POWER FOR SHORT PERIOD OVER A BUMP. CAN REPEAT IT CONSISTENTLY OVER THE SAME AREA ON THE STREET VERY CLOSE TO MY WORKING PLACE. *TR

BRAKES ARE TERRIBLE. VEHICLE COMPUTER CAUSES BRAKES TO UNLOAD WHEN GOING OVER VERY ROUGH ROAD OR POTHOLES. IF STOPPING JUST BEHIND TRAFFIC, COLLISION IS ALWAYS IMMINENT. BRAKES ARE ALSO EXTREMELY SENSITIVE, ESPECIALLY AT LOW SPEEDS. WHILE TRYING TO FEATHER THE BRAKES WHILE BACKING OUT OF A PARKING SPACE (FOR INSTANCE) THE COMPUTER SEEMS TO TELL THE BRAKES TO FULLY CLAMP DOWN WITHOUT APPLYING ADDITIONAL FORCE TO THE BRAKE PEDAL. THIS CAUSES A LURCHING MOTION AS OPPOSED TO A SMOOTH BACKUP AT IDLE SPEED. ALSO, WHEN COMING TO A STOP, THE SLOWER YOU GO, THE MORE SENSITIVE THE BRAKING BECOMES SUCH THAT YOU ARE TRYING TO NOT OVER-APPLY THE ALREADY SENSITIVE BRAKES YOU INEVITABLY END UP STOMPING ON THEM AT THE LAST MINUTE BECAUSE THE AMOUNT OF TRAVEL FROM ZERO TO FULL BRAKING IS MINISCULE. I HAVE OWNED ALL THREE GENERATIONS OF PRIUS. THE FIRST HAD BRAKES THAT WERE UNUSUAL DUE TO THE REGENERATIVE SYSTEM, BUT THEY HAD ACCEPTABLE AMOUNT OF PEDAL TRAVEL AND WERE NOT A PROBLEM. THE SECOND GENERATION'S BRAKES WERE MUCH IMPROVED OVER THE FIRST EDITION AND THEY FELT ALMOST LIKE NORMAL BRAKES. BUT THIS THIRD GENERATION'S BRAKES ARE ABSOLUTELY HIDEOUS! I COMPLAINED ABOUT THEM TO THE DEALER ABOUT A MONTH AGO AND THEY SAID THEY WERE NORMAL AND THAT ALL PRIUS BRAKES WERE LIKE THAT. THAT DOESN'T MAKE IT RIGHT! I AM GLAD ALL THIS PUBLICITY HAS VINDICATED MY ASSERTIONS. *TR

BRAKING SYSTEM. I NOTICE THAT AS I PULL UP TO A STOP SIGN WHILE DRIVING, I APPLY THE BRAKES LIGHTLY TO SLOW DOWN GRADUALLY. I HAVE NOTICED MULTIPLE TIMES THAT WHEN I HIT A BUMPY SPOT OR A POTHOLE, THE CAR LOSES IT BRAKING CAPACITY. I MASH THE BRAKE DOWN HARDER TO SLOW DOWN IF NECESSARY AND THEN IT WORKS FINE. I DON'T KNOW IF IT IS RELATED TO THE CAR'S ABILITY TO ABSORB KINETIC ENERGY AND RECHARGE THE HYBRID BATTERY OR WHAT. I ALSO NOTICED ONE DAY WHEN IT BEGAN TO SNOW HEAVILY, THE ROADS WERE VERY SLIPPERY AND I ALMOST SKIDDED OFF THE ROAD AS I APPLIED THE BRAKES. *TR

I BOUGHT A 2010 PRIUS IN OCTOBER 2009. I BROUGHT THE PRIUS BACK TO THE DEALER, STEVENSON TOYOTA, FOR A PROBLEM THAT WOULD OCCUR WHEN THE VEHICLE BRAKE WAS COMPLETELY DEPRESSED AND THE TRACTION CONTROL LIGHT WOULD COME ON. I ALSO MENTIONED THAT WHEN I WOULD HIT A BUMP OR DRIVE ON ICE, IT DID NOT SEEM THAT THE VEHICLE WOULD STOP PROPERLY AND THAT WHEN HITTING A BUMP, THE VEHICLE WOULD SEEM TO "LURCH FORWARD". THE DEALER SAID THIS WAS A SAFETY ASPECT OF THE VEHICLE AND WAS NORMAL OPERATION. A FEW WEEKS LATER, I CALLED THE DEALER AGAIN TO REITERATE MY CONCERNS ABOUT THE BRAKING PROBLEM AND THE LURCHING FORWARD WHEN HITTING A BUMP, THEY AGAIN REPEATED THAT IT WAS A SAFETY MEASURE NEW ON THE 2010 PRIUS MODELS. NOW THAT THE RECALL IS OUT, I AM SKEPTICAL ON THE VALIDITY OF THEIR STATEMENTS SAYING THAT IT WAS A NEW 2010 SAFETY FEATURE. MY WIFE WHO ALSO DRIVES THE VEHICLE DOES NOT FEEL SAFE DRIVING IN THE SNOW BECAUSE OF THE FEEL OF THE BRAKES WHEN ATTEMPTING TO STOP. I BOUGHT THE CAR FOR HER BUT NOW DRIVE IT MORE BECAUSE SHE DOES NOT FEE SAFE IN THE VEHICLE. *TR

I TOO HAVE NOTICED A STRANGE FEELING OF SPEEDING UP INSTEAD OF SLOWING DOWN WHEN DRIVING OVER A LARGE BUMP ON A STREET IN MY 2010 PRIUS. *TR

I OWN A 2010 TOYOTA PRIUS AND HAVE EXPERIENCED SEVERAL TIMES THE BRAKING FAILURE PROBLEMS RECENTLY DISCUSSED IN THE NATIONAL MEDIA ON SNOW AND ICE AND ON ROUGH ROAD SURFACES. THIS HAS HAPPENED SEVERAL TIMES DURING THE WINTER WEATHER SEASON PARTICULARLY ON SNOW AND ICE. I PURCHASED MY PRIUS IN JULY 2009. *TR

WHILE APPROACHING A STOP SIGN AT A PARTICULAR INTERSECTION WITH A BUMP AND POTHOLE JUST BEFORE THE STOP AREA AT APPROX 30MPH, CAR MOMENTARILY LOSES BRAKING POWER WHEN PASSING OVER BUMP AND POTHOLE. I CAN REPLICATE THIS ISSUE EVERY TIME I APPROACH THIS INTERSECTION, AND IT HAS HAPPENED SEVERAL TIMES SINCE WE BOUGHT THE CAR IN 8/09. PROBLEM WAS REPORTED TO DEALER IN SEPTEMBER, AND WE WERE TOLD THERE WAS NO ISSUE WITH THE BRAKES ON THE VEHICLE. *TR

I HAVE A 2010 PRIUS, WHICH I PURCHASED IN AUGUST 2009. I NOTICED WHEN I APPLY THE BRAKES IF I AM AT A POTHOLE,OR UNEVEN ROAD, THERE IS A "SLIGHT" PAUSE BEFORE THE BRAKES ENGAGE AND STOP THE CAR. THIS HAS OCCURRED AT LEAST 50 TIMES SINCE I PURCHASED THE CAR. *TR

TOYOTA PRIUS 2010 - I HAVE EXPERIENCED IRREGULARITIES WITH MY BRAKES SINCE I PURCHASED THIS CAR ON DECEMBER 28, 2009. I ATTRIBUTED IT TO MY LACK OF EXPERIENCE DRIVING A CAR WITH ANTI-LOCK BRAKES. HOWEVER, I NOW BELIEVE THAT THESE PROBLEMS ARE RELATED TO THE CURRENT INVESTIGATION OF PRIUS BRAKES. TWO THINGS HAPPEN: (1) SEVERAL TIMES WHEN I PLACE MY FOOT ON BRAKE TOO HARD, THE CAR PROPELS FORWARD, (2) UNDER SLICK CONDITIONS AND I PRESS THE BRAKES, THE BRAKES TAKE TOO LONG TO RESPOND AND THE CAR CONTINUES TO MOVE. *TR

2010 TOYOTA PRIUS PURCHASED APRIL 2009. REPORTED TO DEALER SHORTLY AFTER PURCHASE THAT ANTILOCK BRAKE SYSTEM RELEASES BRAKES AND LUNGES CAR FORWARD IF TIRES ENCOUNTER UNEVEN SURFACE (E.G., POTHOLE) WHILE BRAKING. OCCURRENCE HAS RESULTED IN MISSING STOP SIGNS, BUT NO ACCIDENT TO DATE. TOYOTA DEALERSHIP REPORTED THAT THIS WAS NORMAL OPERATION DESPITE MY CALLING THE DEALERSHIP ON TWO SEPARATE OCCASIONS. *TR

IS ANYONE LOOKING INTO THE HEADLIGHT PROBLEM WITH THE 2010 PRIUS MODEL V. I MADE A COMPLAINT TO TOYOTA AND NOTHING RESULTED. THE LOW BEAMS ONLY EXTEND ABOUT 40 FEET, SO THAT YOU CAN ONLY SAFELY TRAVEL ABOUT 30 MPH WITH LOW BEAMS OR OUTRUN YOUR VISION. THERE IS A "CURTAIN" EFFECT. OBVIOUSLY, ONE HAS TO TRAVEL FASTER THAN 30 MPH. *TR

I HAVE A 2010 PRIUS V VEHICLE. EVERY TIME I APPROACH A STOP SIGN THAT HAS A FAIRLY DEEP TRANSVERSE RUT IN THE PAVEMENT IN FRONT OF IT, MY HEAD SNAPS BACK AS THE CAR LURCHES FORWARD. THIS APPEARS TO BE THE MOMENTARY LOSS OF BRAKING THAT IS IN THE NEWS FOR THE 3RD GENERATION PRIUS. IT IS EXTREMELY REPEATABLE...IT HAPPENS EVERY TIME. THE DATE BELOW IS ONLY THE MOST RECENT TIME I'VE DRIVEN ON THAT ROAD. I HAVE NOT HAD AN ACCIDENT. *TR

ON DECEMBER 12, AT APPROXIMATELY 6:15 PM WHILE TRAVELING EAST BOUND ON I-30 NEAR DOWNTOWN DALLAS, I REAR ENDED THE CAR IN FRONT OF ME. I WAS TRAVELING AT APPROXIMATELY 12 MPH AND THE ROADS WERE DRY. I WAS NOT TAIL GATING THE CAR IN FRONT OF ME. THE CAR IN FRONT OF ME WAS CUT OFF AND HE IMMEDIATELY HIT HIS BRAKES. I DID THE SAME. MY CAR BEGAN TO BUCK AND JUMP AND I HIT THE CAR IN FRONT OF ME CAUSING OVER $10,000 WORTH OF DAMAGE TO MY 2010 TOYOTA PRIUS. MY CAR WAS TOWED AND REPAIRED BY TOYOTA OF DALLAS. I REPORTED THE INCIDENT TO THE DEALERSHIP AS WELL AS TO STATE FARM. THE DEALERSHIP HAS TOLD ME OVER AND OVER AGAIN THAT THERE ARE NO PROBLEMS WITH THE BRAKES IN MY VEHICLE. THEY CLAIM I MUST HAVE BEEN TRAVELING TOO FAST OR TOO CLOSE TO THE VEHICLE IN FRONT OF ME. I WAS NOT ISSUED A CITATION BY THE SHERIFF. MY AIR BAGS DID NOT DEPLOY AS I WAS TRAVELING AT APPROXIMATELY 12 MPH. I CONTINUED TO COMPLAIN TO TOYOTA ABOUT THE BRAKES AND THEY SENT AN ENGINEER TO EXAMINE MY VEHICLE ON TUESDAY, FEBRUARY 2 WHO AGAIN TOLD ME THAT THERE WERE NO ISSUES WITH MY BRAKES. THE VERY NEXT DAY, THE NTSB BEGAN AN INVESTIGATION INTO THE BRAKES, AND THIS MORNING, FEBRUARY 4 (2 DAYS AFTER THE ENGINEER INSPECTED MY VEHICLE) TOYOTA ANNOUNCES THAT THERE ARE ISSUES WITH THE BRAKING SYSTEM IN MY VEHICLE. I CONTINUE TO EXPERIENCE THE SAME ISSUES WITH MY BRAKES. I AM AFRAID TO CONTINUE TO DRIVE THE VEHICLE. *TR

MOMENTARY BRAKE FAILURE ON 2010 PRIUS, HAS OCCURRED ON NUMEROUS OCCASIONS. *TR

SEVERAL TIMES SINCE I PURCHASED MY 2010 TOYOTA PRIUS ON DEC. 23RD 2009, I'VE EXPERIENCED MOMENTARY LOSS OF BRAKE CONTROL WHILE BRAKING. IT HAPPENS FOR LIKE A SPLIT SECOND THEN RETURN TO NORMAL. I HAVEN'T NOTICED ANY CONNECTION BETWEEN WHEN IT HAPPENS AND ROUGH ROAD SURFACES. *TR

BRAKING FAILURE ON 2010 PRIUS ON ROUGH OR UNEVEN DRIVING SURFACES. NO FIX HAS BEEN ATTEMPTED OR MADE. THIS IS ANOTHER EXAMPLE OF THE WIDELY REPORTED PROBLEM IN THE 2010 PRIUS. *TR

FROM A DEAD STOP, MOVING FORWARD OR IN REVERSE, BRAKES WILL LOCK OR GRAB & WILL NOT RELEASE EASILY. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT SPEEDS OF LESS THAN 20 MPH IN OVERCAST WEATHER CONDITIONS AND APPROACHING A STOP SIGN AT A BUSY INTERSECTION, THE BRAKES FAILED TO ENGAGE AND THE VEHICLE PROCEEDED WITH CAUTION THROUGH THE INTERSECTION. THE DEALER WAS CONTACTED AND STATED THAT THEY NEVER HEARD OF ANY SIMILAR FAILURES. THERE WERE NO RECALLS OR REPAIRS MADE TO THE VEHICLE. THE FAILURE AND CURRENT MILEAGES WERE 1,400. UPDATED 03/18/10 *BF UPDATED 05/12/10.*JB

WE PURCHASED OUR TOYOTA 2010 PRIUS V MODEL IN JANUARY 9, 2010. DURING THE FIRST WEEK OF DRIVING WE NOTICED THAT IF WE APPLY BRAKE WHILE TURNING LEFT IT WILL SKIT FORWARD JUST MISSING THE DITCH IN OUR DRIVE WAY OR OFF SHOOTING IN THE TRAFFIC LIGHT CROSSING THE MEDIAN. THESE INCIDENTS WERE REPORTED TO THE LOCAL TOYOTA DEALER AND THE DEALER TECH INFORMED US THAT PRIUS IS NOT IN RECALL AND WHEN THEY TEST DRIVE THEY DO NOT FIND ANYTHING WRONG. WELL, WE SAID THAT IT DOES NOT APPEAR EVERY TIME BUT IT DOES VERY OFTEN. THEIR EXPLANATION WAS THAT IT MAY BE BECAUSE OF THE SNOW AS IT IS WINTER AND BEING MICHIGAN ROADS NOT CLEARED ON TIME. *TR

BRAKES ON 2010 TOYOTA PRIUS DO NOT WORK PROPERLY WHEN BACKING UP. DEALER CHECKED BRAKES AND COULD NOT FIND A PROBLEM. *TR

PRIUS 2010, PURCHASED JULY, 2009, DCH TOYOTA, MAMAROCECK, NY. BRAKING PROBLEMS SINCE PURCHASE: BRAKES DISENGAGE, CAR JUMPS, STEERING WHEEL NEEDS TO BE CONTROLLED - WHILE GOING OVER A BUMP, POTHOLE OR ICE. IN ORDER TO ACCOMMODATE TO THIS DEFECT I MUST DRIVE CAR CAREFULLY AND SLOWLY. THIS OCCURS REGULARLY ON ROUTINE DRIVES IN THE METROPOLITAN AREA. *TR

SO THIS IS REGARDING THE 2010 PRIUS I RECENTLY PURCHASED. I BOUGHT THE CAR IN AUGUST OF 2009. THE ONLY PROBLEM I HAVE IS WITH THE BRAKES. SOMETIMES WHEN I HIT A BUMP OR POTHOLE IN THE ROAD, AND I'M STEPPING ON THE BRAKES, I FEEL A SUDDEN ACCELERATION EVEN THOUGH I DO NOT STEP ON THE GAS PEDAL. IF I KEEP MY FOOT ON THE PEDAL I WILL STOP EVENTUALLY, BUT THE SUDDEN ONSET OF ACCELERATION IS QUITE SCARY. THIS HAPPENS FROM TIME TO TIME AND I CAN NEVER PREDICT IT. *TR

BRAKES FAIL ENTIRELY WHEN THE CAR GOES OVER A SMALL BUMP OR CREASE IN THE ROAD. ITS OBVIOUS (NOW) THAT THE DEALERSHIP WAS AWARE OF THIS AND TRIED TO COVER IT UP, AS THEIR IMMEDIATE RESPONSE WAS THAT IT WAS NORMAL AND WAS JUST THE ABS GRIPPING (THEY DIDN'T EVEN WANT TO WRITE MY COMPLAINT ON MY SERVICE REPORT), DESPITE MY REPEATED ASSERTIONS THAT I AM WELL AWARE OF THE DIFFERENCE BETWEEN ABS GRIPPING AND NO BRAKES. BRAKES FAILED ON 3 OCCASIONS BEFORE THE VEHICLE EVEN HAD 4,000 MILES. *TR

2010 PRIUS WHEN DRIVEN OVER POTHOLE WHILE BRAKING SEEMS TO SURGE FORWARD UNTIL THE WHEELS HAVE PASSED THE POTHOLE. THEN BRAKES SEEMS TO CATCH AND PERFORM NORMALLY. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. SHE STATED WHILE BRAKING AT SPEEDS OF LESS THAN 15 MPH AND GOING OVER A POTHOLE AND RAILROAD TRACKS THE BRAKES WOULD INTERMITTENTLY HESITATE TO FUNCTION PROPERLY. WITHIN MOMENTS, THE BRAKES WOULD RESPOND NORMALLY. ON A SEPARATE OCCASION, WHILE TRAVELING IN SNOWY CONDITIONS AT SPEEDS OF UNDER 30 MPH, SHE ATTEMPTED TO DEPRESS THE BRAKE PEDAL AND IT WOULD NOT ENGAGE. THE VEHICLE DID NOT SLIDE; HOWEVER, THE BRAKES DID NOT ENGAGE AND SHE PROCEEDED TO CRASH INTO A CURB CAUSING MODERATE DAMAGE TO THE FRONT PASSENGER'S SIDE TIRE AND RIM. THERE WAS ALSO A LOUD GRINDING NOISE COMING FROM THE VEHICLE AFTER THE CRASH OCCURRED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE SHE WAS AWAITING REPAIRS. THERE WERE NO RECALLS. THE FAILURE AND CURRENT MILEAGES WERE 1200.

2 WEEKS AFTER PURCHASING A 2010 PRIUS (DECEMBER 2009) I WAS SLOWING DOWN TO MAKE A TURN AND WHILE BRAKING I HIT A SMALL POTHOLE IN THE ROAD MY CAR LUNGED FORWARD. AT FIRST I THOUGHT I HAD BEEN REAR-ENDED BUT LOOKED AND SAW THAT THE NEAREST CAR WAS A GOOD 20 FEET BEHIND ME. THE SAME THING HAPPENED TO ME AGAIN LAST WEEK (WEEK OF FEBRUARY 1). THIS TIME I WAS BRAKING FOR A STOPLIGHT WHEN THE CAR HIT A BUMP IN THE ROAD AND AGAIN LUNGED FORWARD. THE LUNGING IS QUICK BUT VERY NOTICEABLE. I HAVE CHANGED MY DRIVING HABITS IN THE HOPES THAT I WON'T REAR-END SOMEONE. I HAVE NOT CALLED IN TO THE DEALERSHIP ABOUT THIS BUT DID FILL OUT A SATISFACTION SURVEY FROM TOYOTA YESTERDAY THAT I GOT DUE TO THE PURCHASE OF THE CAR AND INCLUDED THESE PROBLEMS IN THAT SURVEY. *TR
