2010 TOYOTA PRIUS Service Brakes, Electric Problems

EVER SINCE I PURCHASED MY 2010 PRIUS IN NOVEMBER, 2009 THE BRAKES HAVE BEEN A PROBLEM. WHEN BRAKING WHILE DRIVING OVER A BUMP OR POTHOLE THE CAR LOOSES BRAKING ABILITY AND THERE IS A SURGE OF POWER. THE DEALERSHIP CLAIMS THERE IS NO PROBLEM AND THE RECALL WORK HAS NOT MADE A NOTICEABLE DIFFERENCE. *TT

HAVING PROBLEMS WITH THE BRAKING ON MY 2010 TOYOTA PRIUS. AT SLOW TO MODERATE SPEEDS WHILE I AM BRAKING AND GO OVER A POTHOLE THE CAR SEEMS TO STOP BRAKING AND KEEPS GOING. I THEN HAVE TO DEPRESS THE BRAKE HARDER TO MAKE THE CAR STOP. I HAVEN'T HAD ANY COLLISIONS BECAUSE OF THIS ISSUE BECAUSE I HAVE NOT BEEN FOLLOWING CLOSELY BEHIND A CAR. BUT I BELIEVE IF I WAS, I WOULD HAVE DEFINITELY REAR-ENDED ANOTHER VEHICLE. *TR

I PURCHASED A 2010 PRIUS. WITHIN A 100 MILES, THE BRAKE PEDAL RANDOMLY LOCKED UP, THE BRAKES GRABBED AND BROUGHT MY CAR TO AN ABRUPT HALT. THE BRAKE PEDAL REMAINED LOCKED FOR ABOUT 3-5 SECONDS. THE CAR WOULD NOT MOVE FORWARD OR BACKWARD UNTIL AFTER THE BRAKE PEDAL UNLOCKED ITSELF. INITIALLY THIS HAPPENED IN REVERSE MODE SEVERAL TIMES, THEN IT WAS HAPPENING ONCE A WEEK AND IN FORWARD MODE AS WELL AS REVERSE. I TOOK IT IN FOR REPAIRS, MOST RECENTLY TOYOTA HAD MY CAR FOR A MONTH. NOTE THAT DURING THIS MONTH LONG INVESTIGATION NOTHING WAS DONE TO MY CAR, IT JUST SAT THERE. UPON MY LEAVING THE DEALERSHIP THE BRAKE PEDAL ACTUALLY LOCK UP! THE FIELD REPRESENTATIVE CONFIRMED THE PEDAL TO BE LOCKED AND WOULD NOT RELEASE FOR 30 SECONDS OR LONGER. HE TOOK MEASUREMENTS AND THE ENGINEER TOOK PHOTOS OF THE BRAKE PEDAL AS IT WAS UP IN THE AIR AND NOT DEPRESSED AS A NORMAL PEDAL WOULD BE. HE INSTRUCTED THE SERVICE MANAGER TO SEND ME HOME IN A LOANER CAR AND NOT THE PRIUS BECAUSE OF THE BRAKE PEDAL. I WAS SO RELIEVED THAT SOMEONE FINALLY SAW THE BRAKE PEDAL LOCKED UP AND NOT RELEASE. AFTER AN ADDITIONAL WEEK, THE DEALER CONTACTED ME AND SAID THAT TOYOTA DETERMINED THAT THIS CONDITION IS NORMAL AND THAT THE VEHICLE IS OPERATING AS DESIGNED! WHEN I REQUESTED THAT THE PHOTOS AND MEASUREMENTS OF THE LOCKED UP BRAKE PEDAL BE INCLUDED IN MY SERVICE REPORT, THE FIELD REPRESENTATIVE REFUSED TO FURNISH THAT DATA. INSTEAD, HE DENIED HE WITNESSED THE BRAKE PEDAL LOCK UP. THERE WERE NO CODES, NO WARNING LIGHTS OR WARNING SOUNDS, A SERIOUS SAFETY DEFECT IN ADDITION TO THE BRAKES LOCKING UP. THE DEALER INFORMED ME THAT TOYOTA IS AWARE THAT 1% OF THE PRIUS CARS HAVE THIS PROBLEM AND ARE WORKING ON A FIX! I BELIEVE THAT THE DESIGN AND/OR MANUFACTURING DEFECT HAVE RESULTED IN AN INHERENTLY DANGEROUS PRODUCT AND TOYOTA IS TRYING TO COVER IT UP. PLEASE CHECK INTO THIS, I BELIEVE MANY PEOPLE ARE AT RISK. 1% OF A MILLION CARS IS A LOT OF DRIVERS, PASSENGERS AND OTHERS SHARING THE ROAD. *TR

BACKED 2010 PRIUS UP AND STARTED TO MAKE U-TURN IN DRIVEWAY. WHEN PULLED FORWARD TURNING APPLIED BRAKES AND WELL THERE WERE NONE. TRAVELED ABOUT 15 FEET AND HIT A BRICK WALL. AFTER SOME DELAY THE ENGINE NOW HAD SOME CONTROL AS THE BRAKES ALSO DID. WAITING FOR TOWING INSTRUCTIONS TO GET THE CAR TO GARAGE. MAXIMUM SPEED WAS MAYBE 5MPH. *TR

I HAVE A 2010 PRIUS, AND WHEN I APPLY THE BRAKES AT ANY INTENSITY AND MY VEHICLE HITS A DEFECT IN THE ROAD SURFACE, THE ABS SYSTEM SEEMS TO RELEASE BRAKE PRESSURE TO ALL 4 WHEELS COMPLETELY FOR ABOUT HALF A SECOND. THIS MAKES ME QUESTION THE EFFECTIVENESS OF THE BRAKES IN AN EMERGENCY SITUATION, ESPECIALLY ON HOUSTON'S NOTORIOUSLY NEGLECTED ROADWAYS. I WAS TOLD THAT THIS WAS NORMAL BY BOTH TOYOTA MOTOR CO. AT 1-800-331-4331 AND ALSO BY THE DEALER. TMC INFORMED ME THAT THIS IS THE WAY THAT THE ABS SYSTEM WAS DESIGNED. PLEASE LAUNCH AN INQUISITION AND/OR INVESTIGATION INTO THIS MATTER, FOR THE SAFETY OF THE OWNERS OF ALL TOYOTA PRIUS VEHICLES. *TR

Mileage: 32,204

MY 2010 PRIUS' BRAKES DID NOT RESPOND WHILE ON THE ROAD ON 1/22/11. THEN 2X AGAIN ON 1/23/11. AS A CONSUMER, I DO NOT KNOW WHO REGULATES CAR COMPANIES BUT I HAVE CALLED THE MANUFACTURER AND THEY NEED TO 'DUPLICATE' THE PROBLEM. IN THE PAST, MY BRAKES WOULD ACCELERATE BEFORE IT WOULD CATCH AND THE PROBLEM WAS NOT 'DUPLICATED' BY THE DEALER. THIS TIME THE BRAKES FAILED ME 3X WITHIN 24 HOURS AND I AM EXTREMELY CONCERNED. I WOULD LIKE TO KNOW WHICH GOVERNMENT AGENCY TO REPORT IT TO AND WHAT BETTER OPTIONS I HAVE TO GET A RESOLUTION. *TR

ACCIDENT 12/22/10 TURNED LEFT AS I PULLED INTO PARKING SPACE NEAREST TO HANDICAPPED SPOT. IT WAS VERY SUNNY AND THERE WAS A PATCH OF WHAT LOOKED LIKE ICE. AS THE CAR WENT OVER THAT SPOT IT STARTED TO ACCELERATE. I APPLIED THE BRAKE, ONLY TO FIND MYSELF HITTING THE CURB. AFTER HITTING THE CURB THE CAR LURCHED OVER THE CURB AND I CONTINUED APPLYING THE BRAKE. IN A FRACTION OF A SECOND MY CAR WAS ON THE SIDE WALK, JUST BEFORE IMPACT WITH THE WALL I TOOK MY FOOT OFF THE BRAKE BECAUSE THE CAR DID NOT SEEM TO BE RESPONDING. I DIDN'T KNOW WHAT ELSE TO DO. IT WAS OVER IN SECONDS. BRICKS DENTED IN THE BUILDING, SMASHED GLASS. I PUT THE CAR IN REVERSE AND INTO THE PARKING SPOT. HEAD SPINNING AS TO HOW THIS HAPPENED. I WALKED INTO THE STORE AND APOLOGIZED. THERE WAS GLASS DUST STILL HANGING IN THE AIR. THE WOMAN INSIDE SAID 'CALL THE POLICE'. I THOUGHT THAT WAS A GOOD IDEA. I WAS EAGER TO DEMONSTRATED THAT I WASN'T DRUNK NOR USING ILLEGAL DRUGS. I OFFERED TO TAKE A BREATHILIZER, BUT THEY THOUGHT THAT WASN'T NECESSARY. *TR

Mileage: 30,000

THE BRAKES RELEASE FOR A "SECOND" OR TWO WHEN THE CAR HITS A BUMP, ESPECIALLY IN COLD OR WET WEATHER. MY CAR HAS SLID THROUGH INTERSECTIONS IN THE WINTER A NUMBER OF TIMES BECAUSE OF THIS. I HAVE TO START BRAKING THREE BLOCKS AHEAD IN BAD WEATHER BECAUSE I NEVER KNOW WHEN THE BRAKES WILL RELEASE. THIS IS VERY DANGEROUS. *TR

EVEN AFTER THE BRAKE RECALL REPAIR HAS BEEN PERFORMED, MY CAR'S BRAKES SUDDENLY AND MOMENTARILY LOSE BRAKING POWER OVER UNEVEN OR ROUGH SURFACES. PROBLEM SEEMS COMPOUNDED WHEN TURNING. *TR

Mileage: 16,558

DESPITE THE COMPUTER UPDATE FOLLOWING THE RECALL MY 2010 TOYOTA PRIUS CONTINUES TO HAVE BRAKING PROBLEMS. SINCE THE UPDATE THE CAR ACCELERATES SLIGHTLY WHEN AN UNEVEN ROAD SURFACE IS ENCOUNTERED WHILE BRAKING. TOYOTA SAYS THIS IS NORMAL OPERATION. *TR

Mileage: 2,250

2010 TOYOTA PRIUS OCCASIONAL LOSS OF BRAKE PERFORMANCE IMMEDIATELY UPON START-UP OF VEHICLE. ON 4 SEPARATE OCCASIONS, THERE WAS NOTED LOSS OF BRAKING CAPABILITY AFTER SHIFTING INTO REVERSE IMMEDIATELY AFTER TURNING ON THE IGNITION. THIS CAUSED THE BRAKE PEDAL TO FEEL HARD, AND ALLOWED THE CAR TO SLOWLY MOVE AGAINST THE OPERATOR'S INTENTIONS. AFTER ABOUT 5 SECONDS, THE BRAKES BEGIN TO FUNCTION NORMALLY. A TOYOTA DEALERSHIP TOLD ME IT TAKES A FEW SECONDS FOR BRAKE PRESSURE TO COME UP AFTER STARTING THE VEHICLE AND THAT I SHOULD WAIT BEFORE SHIFTING INTO GEAR. THIS INSTRUCTION SEEMS COUNTERACTIVE TOWARDS SAFETY, AND THE VEHICLE SHOULD NOT BE ALLOWED TO SHIFT INTO GEAR UNTIL BRAKE PRESSURE IS PRESENT. A SIMPLE SOFTWARE UPDATE SHOULD BE ABLE TO ADDRESS THIS CONCERN. *TR

SQUEALING NOISE FROM BRAKES/WHEELS WHEN I PRESS BRAKES ON MY BRAND NEW 2010 TOYOTA PRIUS. IT'S LITERALLY CAUSING ME HEADACHES AFTER DRIVES AND IS A BIG HEALTH HAZARD. I HAVE TAKEN THE CAR TWICE TO MY DEALERSHIP THAT SOLD THE CAR AND THEY ARE RECOGNIZING THE NOISE BUT TELLING THAT IT IS NORMAL FOR ALL PRIUS. IF THAT'S THE CASE THEN IT'S A DEFECT IN PRIUS AS SQUEALING NOISE THAT CAUSES HEADACHES SHOULD NOT BE NORMAL. ALSO, I AM NOT THE ONLY ONE FACING THIS.

MY 2010 TOYOTA PRIUS HAS ALWAYS HAD PROBLEMS BRAKING OVER BUMPY ROADS. AT CERTAIN SPEEDS FIRM BRAKING OVER BUMPS CAUSES THE WHEELS TO FEEL LIKE THEY ARE SLIPPING. TOYOTA RECALLED THE VEHICLE, AND PERFORMED SOFTWARE UPGRADES THAT I FEEL DID NOTHING TO IMPROVE THE SITUATION. I RECENTLY BROUGHT THE CAR BACK TO BE SERVICED AND MENTIONED THAT IT WAS STILL SLIPPING OVER BUMPS BUT THEY CLAIMED THAT THEY COULD NOT REPLICATE THE PROBLEM. THIS IS NOT ONE SPECIFIC INCIDENCE BUT MULTIPLE INSTANCES. *TR

2010 PRIUS WHEN ATTEMPTING TO STOP IF VEHICLE HITS BUMPS, POTHOLES, MANHOLES, ETC., THE VEHICLE BRAKING SYSTEMS LETS GO FOR A MOMENT AND THE VEHICLE WILL KEEP MOVING FORWARD. I HAVE HAD MY PRIUS INTO MY SERVICE DEPARTMENT FOR THE "RECALL" BUT THE PROBLEM CONTINUES. MY SERVICE DEPARTMENT HAS BEEN IN CONTACT WITH TOYOTA WHO TELLS THEM IT IS A CHARACTERISTIC OF THE VEHICLE AND TO ADVISE OWNER OF SUCH. THIS IS A CLEAR SAFETY ISSUE WITH THE VEHICLE. MY FAMILY WILL NOT DRIVE THE CAR AND MY FRIENDS WON'T GET IN THE CAR BECAUSE OF THIS PROBLEM. I WAS TOLD TO EITHER LIVE WITH THE VEHICLE OR TRADE IT IN. NOT AN ACCEPTABLE ANSWER IN MY BOOK. THIS CAN HAPPEN WITH THE VEHICLE 5 OR MORE TIMES A DAY DEPENDING ON WHERE I AM DRIVING. *TR

I HAVE BEEN EXPERIENCE MOMENTARY LOSS OF BRAKING POWER WHILE DRIVING MY 2010 PRIUS ON ROUGH ROAD SURFACE OR POTHOLES MORE THAN 30 TIMES SINCE I OWN THIS VEHICLE. I FILED A COMPLAINT (ODI #10304434) BACK IN FEB 3RD. 2010 BEFORE THE RECALL FROM TOYOTA. MY PRIUS WAS INCLUDED IN THE RECALL, SO I BROUGHT THE VEHICLE BACK TO TOYOTA SERVICE CENTER FOR THE RECALL. TOYOTA UPDATED THE ABS ECU SOFTWARE ON MY PRIUS ON FEB. 2010. SINCE TOYOTA UPDATED THE SOFTWARE FOR THE RECALL, I STILL EXPERIENCE THE SAME PROBLEM MULTIPLE TIMES, AND IT IS NOT ONLY HAPPEN DURING SLOW AND STEADY APPLICATION OF BRAKES, ALSO HAPPEN WHEN I USE THE BRAKE IN MORE SUDDEN FASHION EVEN AT MODERATE SPEED (30-40MPH). I BROUGHT MY PRIUS BACK TO THE TOYOTA SERVICE CENTER AGAIN IN MAY 2010 TO RECHECK THE ABS ECU SOFTWARE, AND THEY SAID THE SOFTWARE IS THE LATEST UPDATED VERSION, AND MY BRAKING SYSTEM IS MEETING THE MANUFACTURE SPECIFICATION. HOWEVER, THIS PROBLEM IS STILL EXIST AS OF TODAY, AND MY CONCERN REGARDING SAFETY OF THIS VEHICLE IS GROWING BECAUSE THIS PROBLEM LEAD TO INCREASE VEHICLE STOPPING DISTANCE AND THUS RAISE THE LIKELIHOOD OF A CRASH OR ACCIDENT. *TR

TOYOTA PRIUS BRAKING PROBLEM; I HAD THE "RECALL" FIX APPLIED; I HAVE NOTICED IN THE LAST TWO WEEKS THAT THE CAR HAS STARTED TO HAVE BRAKE FAILURE AGAIN WHEN GOING OVER BUMPY SURFACES. IT HAD BEEN FINE FOR A WHILE, BUT THIS STARTED HAPPENING AGAIN. I HAVE CONTACTED DEALERSHIP REGARDING THE SAME. *TR

Mileage: 9,900

WHEN ATTEMPTING TO STOP OUR 2010 TOYOTA PRIUS, THE CAR LURCHED FORWARD, AND CONTINUED TO MOVE. I LET OFF THE BRAKE PEDAL, AND REAPPLIED THE BRAKES, BUT THEY DID NOTHING FOR ABOUT 30 SECONDS - AT WHICH POINT THE CAR STOPPED. AFTER CONTACTING BOTH OUR TOYOTA DEALERSHIP, AND THE TOYOTA CUSTOMER SERVICE DEPARTMENT, THEY WILL NOT LOOK AT THE CAR UNTIL NEXT WEEK. *TR

Mileage: 9,950

LIKE ALL OTHER 2010 PRIUS COMPLAINTS, WHEN I APPLY THE BRAKES AND GO OVER A BUMPY SURFACE, THE BRAKES RELEASE CAUSING THE CAR TO JOLT FORWARD. I TOOK MY 2010 TOYOTA PRIUS IN TO THE DEALER DUE TO THE RECALL. THE SERVICE MANAGER STATED MY CAR WOULD BE FIXED IN LESS THAN THIRTY MINUTES. WHATEVER THEY WERE SUPPOSED TO DO TO FIX THE BRAKE PROBLEM DID NOT HAPPEN OR DID NOT WORK. MY CAR STILL JOLTS FORWARD WHEN I AM PRESSING ON THE BRAKES AND I HIT A BUMPY SURFACE. I AM SCARED FOR MY OWN SAFETY. IN ADDITION, I CANNOT HELP BUT WONDER WHAT THIS PROBLEM DOES TO MY TIRES. I HAVE HAD THE CAR SINCE JULY 2009 AND HAVE GOTTEN TWO FLAT TIRES IN THE PAST 11 MONTHS! I HAVE PUT SO MUCH TIME AND MONEY IN TO THIS CAR, AND I HAVEN'T EVEN HAD IT FOR A FULL YEAR. *TR

WE PURCHASED A 2010 PRIUS IN MAY 2010. MY WIFE DROVE THE CAR OUT OF A SHOPPING MALL DRIVEWAY INTO THE LEFT HAND TURN OF THE ROAD AND PULLED UP BEHIND A TRUCK. SHE WAS TRAVELING ABOUT 5-10 MPH ON A NORMAL ROAD, NO POT HOLES OR WET CONDITIONS. SHE HAD HER FOOT RAMMED TO THE FLOOR BUT NO BRAKES! SHE WENT INTO THE BACK OF THE TRUCK, CAUSING EXTENSIVE DAMAGE TO THE FRONT OF THE CAR AND WINDSCREEN. SHE HAD TWO CHILDREN IN THE BACK WITH HER. SEEMS LIKE THEY HAVE NOT FIXED THE PROBLEM! WE WERE TOLD BY DEALERSHIP THAT THERE WERE NO PROBLEMS AND THAT EVERY CAR ON THE LOT HAD BEEN FIXED! NOT REPAIRED YET. NOT SURE I WANT IT BACK. *TR

I OWN A 2010 TOYOTA PRIUS. I WAS HAVING BRAKING ISSUES BEFORE THE SAFETY RECALL. IT WOULD ACCELERATE WHEN I HIT A BUMP WHILE BRAKING. I TOLD BROUGHT MY VEHICLE IN FOR THE FIRST DAY OF THE RECALL AND IT WAS "FIXED." NOW THE PROBLEM IS BACK. MY CAR SUDDENLY ACCELERATES WHEN I'M SLOWING DOWN/BRAKING AND HIT A BUMP. *TR

2010 PRIUS ACCELERATES WHILE BRAKING AND SURGES IN ACCELERATION FROM A STOP WHILE ACCELERATING SLOWLY. MANY BUT NOT ALL OCCASIONS WERE WHILE GOING OVER BUMPS AND/OR WET ROAD. THIS HAS HAPPENED SEVERAL TIMES SINCE OWNING THE CAR. TOYOTA CANNOT DUPLICATE THE PROBLEM IN THE TESTING AND DENIES THAT IT IS REAL. IT HAS BEEN BROUGHT INTO TOYOTA FOR REPAIRS BUT THE PROBLEM PERSISTS. THE CAR IS NOW PARKED AND WE WILL NOT DRIVE IT AS IT IS NOT SAFE. WE FILED A LEMON LAW CLAIM (CA) AND TOYOTA HAS DENIED THE CLAIM WITH A FORM TYPE LETTER. *TR

I HAD THE TOYOTA PRIUS REFLASH DONE ON MY CAR. SINCE THIS REFLASH I HAVE HAD MULTIPLE INSTANCES OF THE BRAKE SURGE. THE MOST RECENT INCIDENT WAS YESTERDAY. I WAS DRIVING DOWN A ROAD GOING ABOUT 25 MPH. I NOTICED AN UPCOMING STOP SIGN AND A SMALL DIP IN THE ROAD. I ENGAGED THE BRAKES AND SLOWED TO ABOUT 10 MPH. UPON HITTING THE DIP THE CAR SURGED FORWARD TOWARD THE STOP SIGN AND INTERSECTION. DESPITE APPLYING EVEN AND STEADY PRESSURE TO THE BRAKE, THE CAR SUDDENLY SURGED FORWARD ON ITS OWN ACCORD. WE HAVE HAD MULTIPLE INSTANCES SINCE THE 'FIX' BY TOYOTA. WE TRIED ARBITRATION TO RESOLVE THE ISSUE, BUT WE HAVE BEEN IGNORED. I AM CONCERNED THAT A FUTURE SURGE WILL INEVITABLY LEAD TO AN ACCIDENT. THIS IS A DEFINITE SAFETY CONCERN THAT MUST BE ADDRESSED! *TR

Mileage: 9,500

I HAVE A 2010 TOYOTA PRIUS AND I RECEIVED THE SOFTWARE RECALL FOR THE BRAKING SYSTEM. AFTER RECEIVING THE SOFTWARE RECALL MY WIFE AND I HAVE BOTH NOTICED THAT THERE ARE INSTANCES WHEN THE BRAKES DO NOT RESPOND AS QUICKLY AS THEY SHOULD WHICH IS SIMILAR TO THE ORIGINAL REASON THE PRIUS WAS RECALLED. *TR

Mileage: 6,000

I CONTINUE TO HAVE A LOSS OF BRAKING WHEN TRAVELING OVER BUMPY SURFACES, EVEN AFTER RECEIVING THE SOFTWARE UPGRADE THAT WAS RELEASED BY TOYOTA. THIS IS ESPECIALLY TROUBLING WHEN I AM TRAVELING OVER AN EXTENDED AREA OF BUMPY ROAD, AND THE BRAKES WON'T WORK AS EXPECTED. *TR

IN MY 2010 PRIUS I HAVE HAD TWO INCIDENCE WITH MY BRAKE WHEN STARTING OUT IN REVERSE. FIRST TIME WAS IN MY DRIVEWAY, DON'T REMEMBER HOW LONG I WAS IN THE CAR UNTIL MY GIRLFRIEND GOT IN.. BUT WHEN I PUT IT INTO REVERSE I GOT A"STIFF" FEELING IN THE PEDAL AND IT FELT LIKE IT WOULDN'T GO DOWN ALL THE WAY... THE CAR SEEMED TO ACCELERATE BACK FASTER THAN EXPECTED WHEN I LIFTED MY FOOT OFF THE BRAKE.... I LIFTED MY FOOT AND PUT THE BRAKE DOWN AND I STOPPED VERY QUICKLY (AS IF I WAS SLAMMING ON THE BRAKES) I THEN TOOK MY FOOT OFF AND REAPPLIED A FEW TIMES AND THE PEDAL FELT FINE. WE THEN DROVE TO THE LOCAL MARKET.. I SAT IN THE CAR WITH THE ACC MODE ON FOR ABOUT 5-8 MINUTES WHILE SHE WENT IN... WHEN SHE CAME OUT I STARTED THE CAR, WENT TO BACK UP AND THE SAME THING HAPPENED.... THIS WAS VERY DISCONCERTING IN A CROWDED LOT WITH LOTS OF PEOPLE WALKING IN CLOSE PROXIMITY TO THE CARS.... I BELIEVE I JUST HIT THE PARK BUTTON... THEN REAPPLIED THE BRAKE (WHICH NOW FELT NORMAL) AND I HAVEN'T HAD THE ISSUE SINCE.... THIS ISSUE HAS BEEN DISCUSSED IN PRIUS FORUMS AT LENGTH AND THERE IS A VERY CONSISTENT THEME TO THE INCIDENTS THAT TOYOTA SHOULD EXPLORE AND DEAL WITH. *TR

I HAVE A TOYOTA PRIUS AND IT HAS BEEN RECALLED ABOUT THE BRAKES. I SENT IT IN TO HAVE THE BRAKES FIXED, BUT I AM STILL HAVING PROBLEMS. WHEN EVER I START TO STOP THE CAR AND THERE ARE BUMPS IN THE ROAD THE CAR SEEMS TO ACCELERATE OR THE BRAKES RELEASE. IT ONLY HAPPENS IF THERE IS BUMPS IN THE ROAD. THE CAR WILL NOT STOP WHEN IT HITS THE BUMPS. WHAT SHOULD I DO? *TR

BRAKING ISSUE - 2010 TOYOTA PRIUS. WE PURCHASED A 2010 PRIUS LAST WEEK, ASKED THE DEALERSHIP IF ANY/ALL RECALL WORK HAD BEEN COMPLETED AND WERE TOLD 'YES.' YET, I BELIEVE THAT THE DEALERSHIP MISREPRESENTED THE FACTS - BOTH MY HUSBAND AND I HAVE EXPERIENCED TEMPORARY LOSS OF BRAKING IN OUR NEW 2010 PRIUS WHILE GOING OVER ROUGH PATCHES IN THE ROAD AND OVER SPEED BUMPS/TRAFFIC CALMING BUMPS. WE BOTH DOUBT THAT THE ABS RECALL WORK WAS ACTUALLY DONE BEFORE WE TOOK POSSESSION OF THE CAR LAST WEEK, SO WE'RE TAKING IT BACK TO THE DEALERSHIP TODAY. I AM NOT AFRAID TO BUY A TOYOTA AND UNDERSTAND THAT OTHER CAR MANUFACTURERS HAVE EXPERIENCED QUALITY ISSUES RESULTING IN RECALLS, BUT I AM VERY UPSET THAT WE ASKED ABOUT THE RECALL WORK AND STILL ENDED UP WITH A CAR WITH BRAKING ISSUES. I DON'T WANT TO DRIVE A POTENTIALLY UNSAFE VEHICLE. *TR

I OWN A 2010 PRIUS. I RECEIVED A RECALL NOTICE AND TOOK IT IN TO THE DEALER FOR REPAIR. NEVERTHELESS, EVEN AFTER THE ALLEGED REPAIR, PROBLEMS STILL HAPPEN WHILE BRAKING.

I HAVE A NEW 2010 PRIUS WITH LESS THAN 1K MILES. ON 4-9-10 WHILE PULLING INTO A PARKING SPOT I EXPERIENCED A SIMULTANEOUS LOSS OF BRAKING COMBINED WITH UNINTENDED SURGE OF ACCELERATION. MY PRIUS JUMPED THE CURB THAT WAS PERPENDICULAR TO THE PARKING SLOT AND STOPPED AS IT SLAMMED INTO A BRICK BUILDING ABOUT 8 FEET BEYOND THE CURB. I UTILIZED MY SAFETY CONNECT BUTTON TO RECORD THE TIME OF THE ACCIDENT AND HAD THE VEHICLE TOWED TO THE DEALER. I CONTACTED TOYOTA CUSTOMER EXPERIENCE CENTER AND NOW HAVE A CASE #. I WAS TOLD THAT SOMEONE WOULD CONTACT ME WITHIN 2 BUSINESS DAYS. I AM NOT AT ALL COMFORTED BY THIS VERY SCARY INCIDENT. I WOULD JUST LIKE TO HAVE MY 2005 PRIUS BACK AS I NEVER HAD ANY PROBLEMS WITH IT. I AM SEEING THAT MY PROBLEM IS NOT UNIQUE BASED ON MANY SIMILAR PROBLEMS ON THIS NHTSA COMPLAINT SITE. *TR

1. BRAKES DISENGAGED ON TWO SEPARATE OCCASIONS WHILE BRAKING TO A RED LIGHT AND WENT OVER UNEVEN PAVEMENT. 2. CAR IS PARKED IN GARAGE. IN THE MORNING I WENT TO START THE CAR AND UPON PUSHING THE START BUTTON THE CAR STARTED VIOLATING SHAKING AND MAKING A CLANKING NOISE. I IMMEDIATELY TURNED CAR OFF AS THIS WAS NOT A NORMAL OCCURRENCE. I PUSHED THE START BUTTON AGAIN AND CAR STARTED NORMALLY. 3. ON 4/1/10 TOOK CAR TO TOYOTA OF ORANGE FOR RECALL FIX OF THE BRAKES. ON 4/2 WHILE PULLING UP TO A STREET FROM A PARKING LOT THE BRAKES DISENGAGED. THE ASPHALT WAS VERY BUMPY IN THE PARKING LOT. I WAS ON A SLIGHT DECLINE. THE BRAKES DISENGAGED AND CAR LURCHED FORWARD. IT WAS WORSE THAN THE OTHER TWO TIMES. IT WAS SCARY. IF THERE WAS A CAR IN FRONT OF ME I WOULD HAVE HIT THEM. *TR

ALTHOUGH I TOOK MY VEHICLE IN FOR THE RECALL (2010 PRIUS) LAST WEEK, THE VEHICLE REPEATED THE LOSS OF BRAKE/SURGE ISSUE THIS MORNING. I ALSO REPORTED TO MY TOYOTA DEALER LAST WEEK ABOUT ABNORMAL, SUDDEN BRAKING. WHEN APPLYING NORMAL PRESSURE TO THE BRAKES, ON SEVERAL OCCASIONS THE BRAKES HAVE LOCKED VIOLENTLY, SENDING ME AND MY PASSENGERS AGAINST OUR SEAT BELTS. TOYOTA CLAIMED THAT THE RECALL MAY MAKE THAT BETTER. IT HAS NOT. THIRDLY, I REPORTED LAST WEEK TO TOYOTA THAT THE CAR HAS ON OCCASION SHAKEN VIOLENTLY AND MADE A LOUD CLANKING NOISE (LIKE A WASHING MACHINE OFF BALANCE) UPON START UP, CAUSING ME TO JUMP OUT F THE CAR FOR FEAR OF IT BLOWING UP. THEY SAID THEY HAD NEVER HEARD OF THIS. MY CO-WORKER, A FELLOW 2010 PRIUS OWNER, REPORTED THE SAME ISSUE. *TR

I HAVE A 2010 TOYOTA PRIUS THAT WAS RECALLED AND REPAIRED IN MARCH 2010. ON APRIL 4, 2010 I WAS DRIVING THE CAR WITH MY WIFE AND WAS UNDER NORMAL BRAKING CONDITIONS WHEN I PRESSED THE BRAKES AND THEY ACTED LIKE THEY WERE ANTI-LOCK. THE PEDAL SKIPPED AND WENT TO THE FLOOR. IT WAS SO NOTICEABLE THAT MY WIFE ASKED WHAT JUST OCCURRED AND I TOLD HER THE BRAKES FAILED FOR A SECOND. I WAS AT ABOUT 20-30 MILES PER HOUR WHEN THIS OCCURRED COMING UP TO A STOP LIGHT. AGAIN THE CAR WAS TAKEN IN FOR THE RECALL PRIOR TO THIS. *TR

DESPITE HAVING HAD THE BRAKE RECALL ITEM FIXED ON MY 2010 TOYOTA PRIUS, I CONTINUE TO EXPERIENCE INSTANCES WHEN I DEPRESS THE BRAKE AND THE CAR SKIDS FROM SIDE TO SIDE WITH A SENSATION THAT THE END OF THE CAR IS LITERALLY LIFTING OFF THE GROUND. THIS HAS HAPPENED TO ME MULTIPLE TIMES AND TOYOTA HAS TOLD ME THAT THE RECALL FIXED ANY CONCERNS, SO THERE SHOULDN'T BE ANYTHING WRONG. ON ONE OCCASION WHEN THIS HAPPENED MY VEHICLE ACTUALLY BUMPED INTO A FIXED OBJECT, CAUSING DAMAGE TO THE FRONT BUMPER. I PURCHASED THIS CAR BASED ON TOYOTA'S REPUTATION AND AM NOW SO MISTRUSTING OF IT THAT I HESITATE TO PUT MY FAMILY IN IT. AS A CONSUMER I STRONGLY FEEL THAT I AND ALL OWNERS OF 2010 PRIUS' SHOULD HAVE THE RIGHT TO OPT TO RETURN OUR VEHICLES TO TOYOTA AND HAVE THE OPPORTUNITY TO SELECT A DIFFERENT NEW OR USED VEHICLE OF THE SAME PRICE FOR WHAT WE PAID FOR OUR CARS. THE PROVEN CONCERNS ABOUT THE 2010 PRIUS SHOULD BE ENOUGH FOR THE NHTSA TO PUT PRESSURE ON TOYOTA TO ALLOW FOR SOME TYPE OF RESTITUTION. IT IS NOT AS SIMPLE AS JUST TRADING IN THE CAR AT ANY RANDOM DEALER BECAUSE THE REPUTATION OF THESE CARS HAS SEVERELY LOWERED THE MARKET VALUE. TOYOTA'S ERRORS SHOULD NOT BE PERMITTED TO HAVE A FINANCIAL IMPACT ON THOSE CONSUMERS WHO PURCHASED THEIR CARS. I WOULD BE HAPPY TO ALLOW NHTSA TO TEST MY VEHICLE FOR A SHORT PERIOD OF TIME IF IT WOULD HELP IN THE RESEARCH OF THIS PROBLEM. *TR

ABS BRAKES FAIL TO ENGAGE WHEN ONE OF THE FRONT TIRES HITS POT HOLE / SLIPPERY BUMPY SURFACE. THE CAR SURGES FORWARD DURING BRAKING BEFORE BRAKING RESUMES. THE RECALL AND FIX TOYOTO IMPIMENTED ON MY CAR ON 2/15 DID NOT ADDRESS THE ISSUE, IT ONLY SHORTENED TO LAG TIME (PERIOD OF EXCELERATION - SURGE FORWARD). THE ISSUE STILL EXISTS AND IS STILL A DANGEROUS SAFETY HAZARD. I REPORTED THIS TO THE DEALER IN SMITHTOWN, NY WHO CONTACTED TOYOTA FACTORY AND THEY ADVISED THE DEALER, WHO ADVISED ME THAT THE CAR OPERATES AS PER SPECIFIATION. THE DEALER AND THE FACTORY DID NOT EVEN LOOK AT MY CAR! I DEMANDED A WORK ORDER WHICH THEY GAVE ME STATING "CAR TO BE BROUGHT BACK AFTER TOYOTA IS CONTACTED ADN ADVISES DEALER ON THE CONDITION". THE NEXT DAY THE DEALER CALLED ME TO SAY TOTOTA ADVISED THE CAR IS WORKING AS PER SPEC. TOYOTA REFUSES TO ADDRESS THIS ISSUE AND THE DEALER WILL NOT LOOK AT THE CAR. THIS IS A SAFETY HAZZARD THAT I SHOULD NOT HAVE TO BE SUBJECTED TO. PLEASE CONTACT ME. THANK YOU DOREEN GEBBIA, NESCONSET, NY

I PURCHASED MY 2010 PRIUS BACK IN JULY OF 2009 AND HAD PROBLEMS STOPPING THE CAR WHEN APPLYING THE BRAKE OVER A BUMP OR A POT HOLE ON THE ROAD. THE CAR WOULD ACCELERATE FOR A SECOND BEFORE COMING TO A FULL STOP. WHEN THERE WAS VOLUNTARY RECALL, FOR ME IT WAS MANDATORY BECAUSE THIS WAS A SERIOUS ISSUE BECAUSE IF THERE WOULD HAVE BEEN A CAR IN FRONT OF ME, OR IF THIS WAS CLOSE TO AN INTERSECTION AND PEDESTRIANS, WHO KNOWS WHAT COULD HAPPEN. I TOOK IT TO THE DEALERSHIP TO GET THE RECALL. THEY TOLD ME IT IS SOME SOFTWARE UPDATE. AFTER GETTING THE VEHICLE SERVICED, I TOOK IT FOR A TEST DRIVE AND NOTICED SLIGHT IMPROVEMENT IN THE RESPONSE WHEN APPLYING THE BRAKE PEDAL. BUT THIS MORNING AS I WAS APPLYING MY BRAKE HEADING TOWARDS THE INTERSECTION TO MAKE A TURN, I HIT A POT HOLE AND THE ACCELERATED AGAIN AND I HAD TO QUICKLY MANEUVER THE VEHICLE TO AVOID COLLISION WITH THE CAR IN FRONT OF ME. WHATEVER THEY DID WITH THE RECALL DID NOT RESOLVE THE BRAKE PROBLEMS.

THE BRAKE FIX ON MY 2010 TOYOTA PRIUS DID NOT SOLVE THE PROBLEM WITH THE BRAKES RELEASING UNDER CERTAIN CONDITIONS. I EXPERIENCED THE PROBLEM 3 TIMES BEFORE THE FIX AND 2 TIMES AFTER. THE ONLY WAY I COULD REPRODUCE THE PROBLEM WAS WHILE BRAKING ON A SNOW COVERED ROAD. SINCE HAVING MY CAR REPAIRED UNDER TOYOTA'S RECALL PROGRAM, I HAD THE BRAKES RELEASE ONCE ON WET ROADS (3/14) AND ONCE ON ICE (3/25).

ON 12/28/09 AT APROX. 6:30 A M, WHILE DRIVING MY 2010 TOYOTA PRIUS, I ATTEMPTED TO STOP ON A ROUGH ICE/SNOW PACKED SURFACE. I WAS TRAVELING AT ABOUT 5 MPH. THE VEHICLE SLID FOR ABOUT 20 TO 25 FEET BEFORE CRASHING INTO A SNOW BANK. THE ABS DID NOT OPERATE, AS I NEVER FELT THE DISTINCT PULSATING IN THE BRAKE PEDAL. THE VEHICLE SEEMED TO ACTUALLY LOOSE ALL BREAKING POWER FOR A INSTANT AND SURGE FORWARD. NO OTHER VEHICLES WERE INVOLVED AND NO ONE WAS INJURED. THE FRONT BUMPER WAS DAMAGED AND THE VEHICLE WAS REPAIRED FOR ABOUT $1,400. AFTER THE VEHICLE WAS REPAIRED, WHILE DRIVING OVER ROUGH SURFACES, AT TIMES, I NOTICED THAT THE BRAKES DID NOT STOP PROPERLY. AT THAT TIME, THERE WAS NO RECALL FOR THE 2010 PRIUS BRAKES. IT FEELS AS IF THE BRAKES STOP WORKING FOR AN INSTANT AND THE VEHICLE SURGES FORWARD. I EVEN REMARKED TO MY WIFE, WHILE DRIVING, THAT THE BRAKED DID NOT FEEL RIGHT WHEN STOPPING SOMETIMES. THERE HAS SINCE BEEN A RECALL FOR THE 2010 PRIUS BRAKES. MY PRIUS IS NOW AT THE TOYOTA DEALERSHIP WHERE THE BRAKE RECALL WILL BE PREFORMED. I HAVE BEEN DRIVING OVER 38 YEARS AND HAVE A VERY GOOD DRIVING RECORD. IT IS MY OPINION, THAT THE ACCIDENT WOULD NOT HAVE OCCURRED HAD THE BRAKES IN MY 2010 PRIUS BEEN WORKING PROPERLY.

2010 TOYOTA PIRIUS ISSUE WITH BRAKES. I RECEIVED A RECALL NOTICE, BROUGHT IT TO DEALER, THEY SUPPOSEDLY FIXED THE PROBLEM. THE RECALL DID NOT CORRECT THE PROBLEM. THERE IS STILL AN ISSUE WITH THE BRAKES. IF YOU HAVE TO BRAKE ON AN UNEVEN SURFACE THE CAR DOES NOT RESPOND IMMEDIATELY. IT SEEMS TO FLOAT OR GLIDE OVER BUMP BEFORE THE BRAKE CATCHES. IT IS A CONSTANT CAUSE OF ANIEXTY WHILE DRIVING. EXTREMELY DANGEROUS BECAUSE YOU CAN CRASH INTO CAR IN FRONT OF YOU ESPECIALLY WHEN CITY DRIVING AS I DO WHEN I COMMUTE TO AND FROM WORK EACH DAY.

ON MY DRIVE HOME FROM THE TOYOTA DEALERSHIP AFTER HAVING THE ABS BRAKE FIX RECALL FIX APPLIED, I APPLIED MY BRAKES TO SLOW DOWN FOR A SPEED BUMP AND WHILE THE CAR ROLLED OVER THE SPEED BUMP THE BRAKES SLIPPED AND THE CAR SEEMED TO SURGE FORWARD.

I WAS DRIVING DOWN LAUREL CANYON IN LOS ANGELES, I HIT MY BRAKES, THEY ACCELERATED AND I HIT THE CAR IN FRONT OF ME. I DID HAVE THE CODE IN MY 2010 PRIUS FIXED HOWEVER THERE WERE STILL SOME MINOR ACCELERATION PROBLEMS AND I WAS SO ANNOYED THAT I DIDN'T SAY ANYTHING. HOWEVER NOW I HAVE RAN INTO THE CAR IN FRONT OF ME. *TR

IT HAS ALSO HAPPENED AGAIN TODAY WHEN I TRIED TO USE THE CRUISE CONTROL. *TR

I LEASED A 2010 TOYOTA PRIUS IN DECEMBER. IMMEDIATELY UPON LEAVING THE DEALERSHIP I NOTICED THAT THE VEHICLE'S BRAKES DO NOT HOLD WHEN YOU HIT A BUMP/POTHOLE. IN FACT, THE CAR SHOOTS FORWARD AND YOU MUST BE PREPARED. I FILLED OUT THE ON-LINE FORM FOR TOYOTA CUSTOMER SERVICE TO GO ON RECORD WITH THEM I HAD THE RECALL SOFTWARE UPGRADE INSTALLED 3 WEEKS AGO, AND WHILE THE PROBLEM IS MUCH LESS SEVERE, THE UPGRADE FIX DOES NOT FULLY CORRECT THIS ISSUE. THIS MORNING, MY VEHICLE'S BRAKES DID NOT HOLD WHEN I WAS BRAKING TO DRIVE OVER A BUMP IN THE ROAD AT 20MPH. I HAVE HAD A FEW MORE MINOR OCCURRENCES, BUT TODAY WAS NOTICEABLE. *TR

MY 2010 TOYOTA PRIUS HAS HAD A DEFECT THAT I NOTICED AFTER PURCHASE. EVERY TIME I BRAKE, WHEN I HIT A BUMP, MY CAR ACCELERATES. THERE WAS A RECALL IN WHICH WE PARTICIPATED ON MARCH 15, 2010 HOWEVER IT DID NOT CORRECT THE PROBLEM. WE ARE EXTREMELY DISSATISFIED AND FEARFUL OF THE POSSIBLE DANGER IT COULD BRING TO OUR FAMILY AND CHILDREN. *TR

I HAVE A 2010 TOYOTA PRIUS THAT HAS HAD THE SOFTWARE UPDATE RECALL PERFORMED. SINCE HAVING THE RECALL DONE, THE BRAKES ON THE CAR SEEM TO WORK EVEN WORSE THAN BEFORE.

I HAVE BEEN HAVING TWO ISSUES WITH THE 2010 PRIUS SINCE I BOUGHT IT ON 29TH DEC 2009. 1. UNABLE TO STOP AND SUDDEN ACCELERATION WHEN HITTING ROUGH /UNEVEN ROAD CONDITION AND TRYING TO STOP AND CONTROL THE VEHICLE. 2. UNABLE TO STOP SOME TIMES WHEN DRIVE AT CITY SPEED LIMIT AND GOING BETWEEN SLOW AND STOP AND SLOW AND FAST AND SLOW KIND OF DRIVING, SOMETIME WHEN PRESSING BRAKE, INSTEAD OF DECELERATING IT START TO ACCELERATE AND TAKES LONGER TO STOP. I HAVE ALREADY BEEN TO TOYOTA DEALERSHIP 3 TIMES OVER THIS ISSUE. FIRST TIME THEY FIXED BRAKE ISSUE. SECOND TIME IT WAS RECALL THAT THEY TOLD WILL FIX THE PROBLEM I AM HAVING. 3RD TIME THEY SAID THEY CAN REPRODUCE THE PROBLEM. BUT I KNOW I FEEL THE ISSUE SOMETIME. AND I CAN NOT JUST LEAVE THE CAR WITH THEM FOR DAYS TO INVESTIGATE AND I CAN CHANGE MY DRIVING PATTERN OR BEHAVIOR EITHER FOR THIS CAR. *TR

I HAD MY 2010 TOYOTA PRIUS SERVICED IN ORDER TO ADDRESS A LOSS OF BRAKE POWER WHEN BRAKING WHILE GOING OVER A BUMP. AFTER THE SERVICING THE PROBLEM HAS CONTINUED. IT IS A BRIEF EVENT BUT CONCERNS ME AS WHEN IT HAPPENS IT FEELS MOMENTARILY AS THOUGH THE CAR IS SPEEDING UP. *TR

I BOUGHT A 2010 PRIUS IN JUNE 2009. SHORTLY AFTER GETTING THE CAR I NOTICED THAT IT SEEMED TO "SLIP" WHEN I WAS DRIVING SLOWLY OVER UNEVEN SURFACES (RAILROAD TRACKS, UNEVEN ROAD SURFACES, UTILITY COVERS). WHEN THE RECALL WAS ANNOUNCED I REALIZED THE "SLIP" I WAS FEELING WAS THE BRAKES NOT WORKING MOMENTARILY. I WENT TO A DEALER AND THE CAR WAS SERVICED. HOWEVER, I HAVE CONTINUED TO EXPERIENCE THIS ISSUE EVEN AFTER THE SUPPOSED FIX. *TR

MY PRIOR PRIUS WAS REPURCHASED BY TOYOTA 09/09 WITH SEVERE ELECTRICAL ISSUES WHICH ONLY ESCALATED. I BELIEVE THE MAN IN CA BECAUSE THAT HAPPENED TO US ON THE HIGHWAY, AND OUR CAR BEHAVED AS IF IT WERE 'POSSESSED'. NOW MY 2010 IS HAVING INTERMITTENT ISSUES, INCLUDING AN ANTI-SKID/ BRAKING LIGHT THAT WE'D THOUGHT WAS REMEDIED BY RESETTING AN ABS ACTUATOR FRIDAY-IT WAS ON SINCE TEST DRIVING THE CAR-BUT I WAS TOLD MANY EXCUSES, AND EVENTUALLY THEY WERE AWARE BUT DID NOT KNOW HOW TO CORRECT THIS. (?) I'M CONCERNED ABOUT DRIVING THIS VEHICLE AS MY 2007 TRAPPED US IN THE CAR TWICE-911 CALLED IN A PANIC-PLUS MY SMALL DAUGHTER'S SAFETY WAS AT RISK JUST BY OWNING THAT CRAZY CAR. PLEASE SEE IF YOU CAN LOCATE THAT CAR AND INSPECT IT-YOU WILL SEE THIS IS NOT SOME CHANCE SITUATION-AND NOW I AM EXTREMELY CONCERNED ABOUT OUR NEW CAR 'PERFORMING AS DESIGNED' WHEN BRAKE WARNING LIGHT COMES ON WHEN APPLIED! FEEL FREE CONTACTING ME ON THIS!! *TR

I BROUGHT MY 2010 PRIUS TO SERVICE THE RECALLED BRAKE SOFTWARE ISSUE. PREVIOUS TO THIS, I NOTICED BRAKING PROBLEMS WHEN ON SLIPPERY AND/OR BUMPY ROADS WHERE THE BRAKES WOULD 'STOP BRAKING' FOR 1-2 SECONDS, AND GIVE A FEELING THAT THE CAR WAS LUNGING FORWARD WHEN ATTEMPTING TO DECELERATE. I BROUGHT THE CAR IN TO HAVE THE BRAKE SOFTWARE UPGRADED. ON MARCH 12TH I WAS DRIVING ON WET ROADS, WITH SOME POTHOLES, IT WAS FAIRLY BUMPY. I SLOWED THE CAR AS USUAL AND NEAR THE STOPLIGHT THE CAR FAILED TO DECELERATE FOR 1-2 SECONDS, AND I THOUGHT I WAS GOING TO CRASH INTO THE CAR IN FRONT OF ME. AFTER 1-2 SECONDS THE BRAKES CAUGHT AGAIN AND I HAD TO SLOW DOWN MUCH MUCH FASTER TO AVOID HITTING THE VEHICLE IN FRONT. MY CONCERN IS THAT THE BRAKE SOFTWARE UPGRADE DID NOT FIX THE PROBLEM, AND I CONTINUE TO BE AT RISK. *TR

WHILE DRIVING ON A RESIDENTIAL STREET AT APPROXIMATELY 25 TO 30MPH, I PUT ON BRAKES FOR A SPEED BUMP AND MY 2010 PRIUS LOST BRAKE POWER FOR A (VERY SHORT) PERIOD OF TIME. THIS SAME EVENT HAPPENED ON 3 SEPARATE OCCASIONS FROM NOVEMBER OF 2009 TO THE PAST WEEK. IN ALL CASES THE STREET WAS DRY AND THE CAR WAS TRAVELING AT OR BELOW THE SPEED LIMIT. ONE OCCURRENCE WAS AS DESCRIBED ABOVE AND THE OTHER TWO WE ON SOMEWHAT OF A ROUGH SPOT IN THE ROAD. *TR

ON FEB 1, 2010, I WAS APPROACHING A STOP LIGHT INTERSECTION AT ABOUT 7 MPH. WHEN APPLYING THE BRAKES IT WAS LIKE STEPPING ON A SOLID STEEL POLE OR ICE SKATES. THE PEDAL WOULD NOT DEPRESS AND THE BRAKES WOULD NOT ENGAGE. I RELEASED BRAKE PRESSURE AND AGAIN PRESSED THE PEDAL AND THEN THE BRAKES OPERATED SATISFACTORILY. THE STREET WAS SMOOTH ASPHALT, DRY AND IN GOOD CONDITION WITHOUT BUMPS. ON FEB 28, 2010 THE DEALER (LAKE CITY TOYOTA) ACCEPTED THE VEHICLE AND PERFORMED THE "SERVICE CAMPAIGN AOB ABS ACTUATOR ECU UPDATE". *TR

PURCHASED 2010 PRIUS ON AUG LL,09. HAVE RETURNED TO DEALER 5 TIMES, BEGINNING ON SEPT.29, 09, TO REPORT SAME PROBLEM...WHICH IS THAT AT RANDOM TIMES WHEN I SHIFT FROM "P" TO EITHER "D" OR "R", THE VEHICLE LUNGES AND WHEN I APPLY THE BRAKE, IT IS LIKE HITTING A BRICK WALL. THIS PROCESS IS REPEATED SEVERAL TIMES IN SEQUENCE...LUNGE, BRAKE, LUNGE, BRAKE..THEN IT CORRECTS ITSELF AND DRIVES NORMALLY. I CANNOT PREDICT WHEN THIS WILL OCCUR, SOMETIMES IT IS WEEKS AND HUNDREDS OF MILES BETWEEN OCCURRENCES; SOMETIMES ONLY A FEW MILES AND HOURS BETWEEN INCIDENTS. THE DEALER ALWAYS SAYS THEY HAVE NOT BEEN ABLE TO REPRODUCE THE PROBLEM, THEREFORE NO DIAGNOSIS OR REPAIR. I HAVE REPORTED TO TOYOTA CUSTOMER SER. AND WAS ASSIGNED A CASE #. HAVE HAD ONGOING CONVERSATION WITH TCS REP TO REPORT THIS AND SEVERAL OTHER PROBLEMS, I.E. VARIOUS WARNING LIGHTS AT INAPPROPRIATE TIMES..."KEY DETECTED IN VEHICLE" WHILE DRIVING DOWN THE ROAD... ETC. AM ALWAYS TOLD "SCAN SHOWS NO PROBLEMS". I THINK THERE IS A PROBLEM WITH ELECTRONICS. UNSAFE, FRIGHTENING. LATEST INCIDENT ON 3/05/10. DEALER INSTALLED SOFTWARE FIX FOR BRAKE RECALL ON 2/10/10. AT TIMES MUST REPEATEDLY MOVE GEAR SHIFT LEVER BEFORE IT RESPONDS. *TR

2010 TOYOTA PRIUS GAVE ME IN TWO DIFFERENT OCCASIONS THE FEELING THAT THE BRAKE WAS NOT WORKING. IN BOTH CASES I WAS DRIVING SLOW AND TRACTION CONTROL LIGHT CAME ON. IN ONE CASE I WAS BACKING UP FROM MY GARAGE; IN THE OTHER CASE I WAS TRANSITIONING FROM A SMALL DOWNHILL EXIT TO A FLAT STREET. *TR

WHEN BRAKING, ALL OF A SUDDEN THE CAR LURCHES FOR A SECOND OR SO, AS IF ON ICE. THIS HAPPENED 3 TIMES IN DIFFERENT CIRCUMSTANCES, ONCE NOT RELATED TO A POTHOLE. TOYOTA DEALER IN AVON CT APPLIED THE CORRECTION TO THE SOFTWARE, AND THE NEXT WEEK (LAST WEEK) THE SAME THING HAPPENED AGAIN, WHEN I HIT A WIDE, BUT NOT DEEP POTHOLE WHILE BRAKING, JUST BEFORE STOPPING AT THE END OF A HIGHWAY EXIT RAMP. IN THIS SITUATION, IT WAS FORTUNATE THAT NO CAR WAS IN FRONT OF ME AT THE LIGHT. ADDITIONALLY I HAD A PROBLEM WITH SUDDEN ACCELERATION A COUPLE TIMES WHEN DRIVING AT SLOW SPEED. *TR

I JUST PICKED UP MY 2010 TOYOTA PRIUS FROM THE DEALERSHIP FOR THE SECOND TIME SINCE THE BRAKE RECALL. THIS IS THE THIRD TIME MY PRIUS HAS BEEN IN FOR SERVICE ON MY BRAKES. THEY PERFORMED THE RECALL AND KEEP TELLING ME THAT MY CAR IS FUNCTIONING PROPERLY AND THAT ALL HYBRIDS BRAKE THIS WAY. I WILL ADMIT MY PRIUS STOPS QUICKER THAN BEFORE THAN THE RECALL HOWEVER I STILL NOTICE THAT IT SURGES FORWARD BEFORE THE CARE STOPS AT TIMES. IN THE 2 WEEKS I HAD THE CAR BACK AFTER THEY PERFORMED THE RECALL I AND MY HUSBAND NOTICED THAT THE BRAKES STILL SURGED FORWARD BEFORE STOPPING. I PICKED UP MY CAR TODAY AND I NOTICED IT AGAIN ON MY WAY HOME. WHAT IS IT GOING TO TAKE TO GET THIS CAR FIXED PROPERLY? I DO NOT FEEL SAFE DRIVING IT AROUND, AND I HAVE YOUNG CHILDREN. I WANT SOMEONE TO LOOK INTO WHY THESE RECALLS ARE MAKING THE PROBLEM ALITTLE BETTER BUT NOT FIXING THE PROBLEM. IF TOYOTA DOES NOT KNOW HOW TO FIX IT THEN MAYBE THEY NEED TO BUY THESE UNRELIABLE DEATH TRAPS BACK FROM THEIR CONSUMERS AND STOP FEEDING US A LINE ABOUT HOW THIS IS NORMAL AND ALL HYBRIDS DO THIS. *TR

I REALIZE THERE ARE PRIVACY CONCERNS AS AN OWNER, AND I'M NOT LOOKING TO PUT EMPHASIS ON MYSELF, HOWEVER; AFTER SUPPOSED REPAIRS TO THE BRAKE SYSTEM I AM WORRIED THAT THE ELECTRONIC UPDATE TO THE PRIUS 2010 WAS NOT SUFFICIENT.

1. ON FRIDAY, FEBRUARY 26TH, 2010 I HAD MY 2010 PRIUS "FIXED" AT A TOYOTA DEALERSHIP FOR THE BRAKE/ACCELERATION RECALL. I HAD EXPERIENCED BRAKING/ACCELERATION ISSUES ONLY 3 TIMES IN 5 MONTHS OF OWNING THE VEHICLE BEFORE HAVING IT RECALLED. 2. IN THE LAST 2 DAYS I HAVE EXPERIENCED THE BRAKING/ACCELERATION PROBLEM TWICE. THE PROBLEM SEEMS TO HAVE GOTTEN WORSE. ESSENTIALLY WHAT OCCURS IS A SUDDEN JERKING FORWARD OF THE CAR, WHETHER OR NOT THE BRAKING SYSTEM IS DEPRESSED, TYPICALLY WHEN GOING OVER ROUGH TERRAIN OR UNEVEN PAVEMENT. I OCCURRED BOTH TIMES AT RELATIVELY LOW SPEEDS BETWEEN 10-20 MILES AN HOUR AND THE ACCELERATION LASTED ONLY A SECOND OR 2, BUT IS VERY ALARMING, ESPECIALLY IF A CAR IS IN FRONT OF YOU. *TR

WE BOUGHT A 2010 PRIUS LAST JULY. SINCE BUYING THE PRIUS WE HAVE HAD THE BRAKES COMPLETELY STOP WORKING, DURING BRAKING AFTER DRIVING OVER A SMALL BUMPS (MANHOLE COVER, DISTURBED PAVEMENT, SMALL POTHOLE). THIS HAS NOW HAPPENED AROUND 10 TIMES. FORTUNATELY, AFTER COMPLETELY RELEASING THE BRAKES WOULD AGAIN BRAKE AFTER APPLYING INCREASED PRESSURE ON THE BRAKE PEDAL. MOST RECENTLY THE BRAKING FAILURE OCCURRED THE DAY IMMEDIATELY FOLLOWING HAVING THE 'BRAKE RECALL" MAINTENANCE PERFORMED BY TOYOTA TO CORRECT THE BRAKING PROBLEM. THE "FIX" IS OBVIOUSLY NOT CORRECTING THE PROBLEM. THIS IS A MAJOR SAFETY CONCERN. THE BRAKES ONCE GAVE OUT WHILE APPROACHING A PEDESTRIAN IN A CROSSWALK. IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS SERIOUSLY INJURED OR WORSE. PLEASE HELP. WHAT SHOULD I DO NOW? *TR

I BOUGHT A 2010 PRIUS IN NOVEMBER OF 2009. I SOON DISCOVERED THAT THE CAR WOULD NOT BRAKE PROPERLY AND A COUPLE OF MONTHS LATER HEARD ABOUT THIS ISSUE ON THE NEWS. I BROUGHT MY CAR IN FOR THE RECALL AND A SOFTWARE PATCH WAS APPLIED TO THE CAR TO RECTIFY THE SITUATION. THAT WAS 5 DAYS AGO. UPON LEAVING THE DEALERSHIP, THE CAR DID FEEL BETTER; THE BRAKES DID NOT FEEL AS SENSITIVE. HOWEVER, IN THE PAST FIVE DAYS I HAVE EXPERIENCED THE SAME EXACT SENSATION OF THE CAR NOT BRAKING WHEN I HAVE BEEN RIDING OVER A ROUGH PATCH OF ROAD AT A SPEED OF LESS THAN 30 MPH. BUT IT'S NOT JUST A FEELING. THE CAR SURGES FORWARD MOMENTARILY. IT ALMOST FEELS LIKE I AM SKIDDING ON ICE. I DO NOT FEEL SAFE IN THIS VEHICLE DESPITE THE FACT THAT THE FOLKS AT MY TOYOTA DEALERSHIP SAID THIS PROBLEM WAS "NOT A SAFETY ISSUE." I DISAGREE. I AM AFRAID THAT I WILL LOSE BRAKING ABILITY AND HIT SOMETHING OR SOMEONE OR END UP IN AN INTERSECTION INVOLUNTARILY. I HAVE A FIVE YEAR OLD DAUGHTER. I REALLY WANT MY MONEY BACK. I WOULD NEVER HAVE PURCHASED THIS CAR IF I HAD KNOWN IT HAD FAULTY BRAKES. I FEEL BURNED BY TOYOTA. *TR

HOWEVER ON 19 FEB 10 I HIT THE BRAKES TO STOP AND IT FELT LIKE THE SIMPLY MADE A GRINDING SOUND AND BARELY SLOWED AT ALL...THE HARDER I PRESSED THE LESS THE SEEMED TO APPLY.

WHILE TURNING INTO A DRIVEWAY TO TURN AROUND TO GRAB A PARKING SPOT, I APPLIED THE BRAKES AND THEY COMPLETELY RELEASED AND I SLAMMED TO THE SNOW PILED AT THE ENTRANCE TO THE DRIVEWAY. THE FRONT BUMPER COVER GOT A HOLE PUNCHED INTO IT THE SIZE OF A BASEBALL FROM THE FROZEN SNOW. SINCE THEN THE BRAKES HAVE RELEASED WITHOUT INCIDENT BUT NOT WITHOUT CONCERN. I CALLED AND REPORTED THE PROBLEM TO MY TOYOTA DEALER AND HE ASKED "DO I HAVE AN ERROR SHOWING UP ON THE DASH SCREEN" AND I SAID "NO". I ASKED WAS THERE A NEW UPDATED PROGRAM AND HE SAID HE DID NOT KNOW ANYTHING ABOUT IT AND THEY DON'T HAVE A FIX ANYWAY. THIS WAS BEFORE THE CAR WAS RECALLED BY A COUPLE OF WEEKS BUT AFTER TOYOTA HAD STARTED LOADING A DIFFERENT PROGRAM ONTO THE CAR. ON FEB. 17, 2010 TOYOTA DID FLASH THE CAR'S COMPUTER TO FIX THE PROGRAM ISSUES. I WOULD LIKE TOYOTA TO HAVE THE FRONT BUMPER COVER REPAIRED. THANKS. *TR

I OWN A 2010 TOYOTA PRIUS. I HAVE EXPERIENCED SOME DANGEROUS OCCURRENCES WHILE DRIVING. 1) OCCASIONAL LOSS OF TRACTION (FOR A SECOND+-). PROBLEM HAS OCCURRED AUG, 2009 - PRESENT. USUALLY OCCURS WHEN HEADING DOWNHILL OR WHEN DRIVING OVER A MANHOLE OR DRAINAGE COVER. CAR FEELS AS IF SLIPPING OR AIRBORNE FOR A MOMENT.. 2) FREQUENTLY IMMEDIATELY AFTER STARTING CAR, AT SLOW SPEEDS OF ONLY 0-5 MPH, CAR IS JERKY EACH TIME BRAKE IS APPLIED. PROBLEM HAS OCCURRED AUG, 2009 - PRESENT. PASSENGERS ARE ACTUALLY JERKED, AS IF DRIVER WAS APPLYING BRAKES TOO SUDDENLY. EVEN WITH GREAT ATTEMPT TO STOP SMOOTHLY AND GRADUALLY, IT IS IMPOSSIBLE. BRAKES GRAB AND JERK. THIS OCCURS BOTH IN REVERSE AND FORWARD, YET NOT EVERY TIME ENGINE IS STARTED. IT LASTS FOR ONLY A MINUTE OR SO, BUT MAKES MANEUVERING WHILE PARKING OR ENTERING TRAFFIC UNSAFE, AS WELL AS MAKING DRIVER LOOK INEPT. I CANNOT FIGURE OUT IF THIS IS A BRAKING OR ACCELERATION PROBLEM. WHEN CALLING A TOYOTA DEALER (NOV, 2009), I WAS TOLD THEY HAD NO SIMILAR REPORTS OF THESE PROBLEMS AND OFFERED NO SOLUTION. MY CONCERN HAS INCREASED WITH THE RECENT RECALLS WHEN CALLING A TOYOTA DEALER PREVIOUSLY, I WAS TOLD THEY HAD NO SIMILAR REPORTS OF THESE PROBLEMS.

IT'S THE ONLY TIME THIS HAS HAPPENED TO ME SINCE BUYING THE PRIUS LAST NOVEMBER, BUT BECAUSE OF THE UNCERTAINTY I READ TODAY ABOUT WHETHER TOYOTA WOULD ISSUE A RECALL IN THE U.S. AFTER DOING SO IN JAPAN FOR THE SAME CARS, I THOUGHT IT WOULD BE WORTHWHILE TO SUBMIT THIS TO YOU. *TR

I PURCHASED A PRIUS 2010 IN THE SUMMER OF 2009. I CALLED MY DEALER A WEEK AGO TO REPORT THAT I TOO HAD EXPERIENCED THE BRAKING ISSUE THAT WAS REPORTED ON THE NEWS. I WAS NOT SURE IF THE CAR WAS SKIDDING THE FIRST TIME I EXPERIENCED IT, I WAS GOING SLOWLY AND PUT ON BRAKES OVER A SLIPPERY PATCH AND THE CAR LURCHED BEFORE BRAKING, BUT THEN IT HAPPENED AGAIN OVER A ROUGH SURFACE. WHEN I REPORTED THIS TO THE SERVICE DEPARTMENT OF MY DEALER, CONICELLI TOYOTA OF SPRINGFIELD, PA, I WAS TOLD THAT NO RECALL HAD BEEN ANNOUNCED, NO OTHER CONCERN OR CARE WAS GIVEN TO ME AT THAT TIME. I DID ASK FOR THE CONTACT INFORMATION OF THE COMPANY AND WAS GIVEN AN 800 NUMBER AND THE WEBSITE. I TRIED CALLING THE CUSTOMER SERVICE LINE OF TOYOTA TWICE TO REPORT MY EXPERIENCE, AND WAS ON HOLD FOR OVER 10 MINUTES BEFORE HANGING UP WITHOUT BEING ABLE TO LEAVE A MESSAGE. I CONTACTED MY DEALER AGAIN AND SPOKE WITH THE CUSTOMER RELATIONS MANAGER, I ASKED THAT THEY REPORT MY EXPERIENCE TO YOU AND THAT THEY WORK TO ADVOCATE FOR A SOLUTION FOR THE BRAKE ISSUE. I AM AWAITING A RESPONSE FROM THEM. I AGAIN TRIED THE 800 NUMBER WITHOUT SUCCESS AND THEN ACCESSED YOUR WEBSITE. I WAS UNABLE TO LOCATE A PLACE TO SEND OR POST MY COMMENT/CONCERN, SO I AM WRITING THIS LETTER. PLEASE ADD ME TO THE 210 COMPLAINTS YOU HAVE REPORTED FOR THE PRIUS BRAKING PROBLEM. I AM DEEPLY CONCERNED THAT TOYOTA 'FIXED' THE PROBLEM ON THE PRODUCTION LINE BUT WAS NOT PROACTIVE IN FINDING A CORRECTION FOR THE MODELS PRODUCED BEFORE JANUARY 2010. I WILL BE CONTACTING MY LAWYER AND OTHER AUTHORITIES ABOUT THIS ISSUE. MY SAFETY AND THE SAFETY OF MY FAMILY AND THOSE THAT SHARE THE ROAD WITH ME ARE OF UTMOST IMPORTANCE TO ME. I AM CONCERNED THAT THEY ARE NOT OF THE UTMOST CONCERN OF TOYOTA, WHO WOULD LEAVE US ALL AT RISK UNLESS PUBLIC PRESSURE IS BROUGHT TO BEAR. *TR

1. I LIVE IN MINNESOTA. AFTER THE FIRST BIG SNOWSTORM WHEN I WAS BRAKING ON SNOW AND ICE, THERE WAS A VERY STRONG BURNING RUBBER-LIKE BURNING SMELL, AND THE BRAKING CHANGED. I STARTED SLIDING THROUGH STOP SIGNS AND INTO INTERSECTIONS WHEN ON ICY PAVEMENT. I WAS VERY CONCERNED AND TOOK THE CAR TO THE DEALERSHIP ON DECEMBER 12. THEY REPORTED THERE WAS NOTHING WRONG WITH THE CAR. 2. ON JANUARY 5, I WAS ON A TOTALLY ICED OVER STREET IN PARK RAPIDS, MINNESOTA. I MADE A LEFT TURN, THEN WAS SLOWING DOWN TO MAKE A RIGHT TURN INTO A PARKING SPOT. I WAS GOING VERY SLOWLY. I DEPRESSED THE BRAKE, BUT THE CAR FAILED TO SLOW DOWN. I KEPT SLIDING AND HIT THE CEMENT PARKING MARKER, WHICH PUNCTURED THE FRONT OF THE CAR (IN THE BUMPER AREA). 3. NOTHING HAS BEEN DONE, AND I AM AFRAID TO DRIVE THE CAR.

I HAVE HAD PROBLEMS WITH MY BRAKES WORKING IN MY 2010 TOYOTA PRIUS. I WAS DRIVING ON A COLD, WET ROAD THAT WAS BENDING TO THE RIGHT. I PRESSED THE BRAKE PEDAL TO SLOW THE CAR, THE CAR STUTTERED THEN ACCELERATED WHILE I WAS BRAKING. THE CAR SLID OFF THE ROAD, INTO A DITCH, AND ACCELERATED ITSELF OUT OF THE DITCH ON THE SIDE OF THE ROAD, THE WHOLE TIME I WAS DEPRESSING THE BRAKE PEDAL. NO ONE WAS INJURED, NO PROPERTY DAMAGE WAS SUSTAINED, AND THERE WERE NO OTHER WITNESSES. THE LEFT FRONT BUMPER OF MY CAR SUSTAINED BODY DAMAGE THAT HAS NOT BEEN REPLACED OR FIXED. THE LEFT FRONT WHEEL WELL WAS PUSHED OUT OF PLACE SO THAT WHEN I TURNED THE STEERING WHEEL AT A SHARP RIGHT, THE LEFT FRONT TIRE WOULD RUB AGAINST THE HARD PLASTIC WHEEL WELL. I HAD TO PAY TO GET THE WHEEL WELL PUSHED AND BOLTED BACK INTO PLACE. THIS IS THE INCIDENT THAT TOOK PLACE ON JANUARY 28TH. PRIOR TO THIS INCIDENT, I HAVE ALSO HAD OTHER TIMES WHEN THE BRAKES FAILED, MOST OFTEN WHEN I WAS DRIVING AT NIGHT WHEN IT WAS COLDER OUTSIDE. THEY HAD FAILED AT LEAST THREE TIMES WHILE I WAS DEPRESSING THE BRAKES TO STOP AT A STOP SIGN. WHILE I DEPRESSED THE BRAKES THE CAR WOULD JUMP FORWARD AND ACCELERATE INSTEAD OF SLOWING.

WHEN DEPRESSING THE BRAKES DUE TO APPROACHING A STOP LIGHT, THE VEHICLE TRAVELED OVER A MAN HOLE COVER WHICH WAS UNEVEN WITH THE ROAD SERVICE. THE BRAKES APPEARED TO RELEASE, THE CAR DRIFTED FORWARD 3-5 FEET, AND THEN THE BRAKES RE-ENGAGED. *TR

TOYOTA PRIUS 2010, HAVING DIFFICULT BACKING OUT OF MY GARAGE BECAUSE THE BRAKE IS EXTREMELY TIGHT. AFTER I EVENTUALLY BACKED OUT, I DROVE A FEW YARDS FORWARD AND THEN TESTED IT BACKWARD, THE BRAKE FELT NORMAL. *TR

MY 2010 PRUIS BRAKE PROBELM AS REPORTED IN THE NEWS. *TR

WHILE APPLYING MODERATE PRESSURE TO THE BRAKES ON MY 2010 PRIUS AND WHILE DRIVING OVER A BUMPY ROAD, THE BRAKES SEEM TO MOMENTARILY, BUT COMPLETELY FAIL. THEN THE CAR SEEMS TO BRIEFLY ACCELERATE (OR AT LEAST FREE-WHEEL) BEFORE THE BRAKES FEEL LIKE THEY'RE STARTING ENGAGE AND WORK AGAIN. THIS HAS HAPPENED WITH THIS NEW CAR SINCE THE DAY I PURCHASED IT IN JULY OF 2009. IT DOES IT EVERY SINGLE DAY, AS I DRIVE OVER THE SPEED BUMP WHILE DRIVING OUT OF THE PARKING GARAGE NEAR MY WORK. *TR

SINCE I BOUGHT MY PRIUS BACK IN JULY 2009, MY BRAKES HAVE BEEN GREAT EXCEPT FOR THE 5 OR 6 TIMES WHEN THE BRAKES DISAPPEARED FOR A SECOND AS I PULLED UP TO A STOP SIGN ON A BUMPY ROAD. IT'S HAPPENED TWICE AT ONE STOP SIGN WHERE I DRIVE JUST ONCE A WEEK. THAT ONE HAS A BIG DIP IN THE ROAD WHERE THEY HAVE REPLACED A WATER LINE AND THEN REPAVED. MY OCCURRENCES HAVE ALL BEEN WITHIN 20 FEET OF THE STOP SIGN AND NEVER NEAR A CAR OR PEDESTRIAN FORTUNATELY. I NOW HAVE 14,000 MILES ON THE CAR. WITH SOMETHING THIS RARE, THE DEALERSHIP WAS OF COURSE UNABLE TO REPRODUCE THE PROBLEM. THE NEXT DAY TOYOTA ANNOUNCED THAT IT HAD FIXED THE PROBLEM IN LATE JANUARY ON THE LINE BUT HAD NO FIX TO OFFER US YET. BRAKES ARE GREAT OTHERWISE; THE BEST I'VE HAD. RECENTLY I HAVE HAD PLENTY OF OPPORTUNITY TO TEST ABS, TRACTION CONTROL AND STABILITY CONTROL. NO PROBLEMS EXCEPT FOR THOSE HALF-DOZEN INCIDENTS. *TR

Mileage: 14,000

WHILE DRIVING A 2010 TOYOTA PRIUS IT SOUNDED LIKE THE ROTORS WERE SQUEALING SO LOUD WE HAD TO PULL OVER AND CHECK THE ROTORS AND BRAKES. HOWEVER, NOTHING LOOKED UNUSUAL SO WE SLOWLY DROVE BACK HOME. ME AND MY WIFE THEN PROCEEDED TO RETURN HOME SLOWLY AND THE SOUND CONTINUED ALL THE WAY HOME (10 MILES). SINCE THEN WE HAVE PARKED THE VEHICLE TO AWAIT RESULTS OF RECALL THAT, WHICH HAS BEEN ANNOUNCED TODAY. *TR

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). [XXX] TO WHOM IT MAY CONCERN: I PURCHASED A PRIUS 2010 IN THE SUMMER OF 2009. I CALLED MY DEALER A WEEK AGO TO REPORT THAT I TOO HAD EXPERIENCED THE BRAKING ISSUE THAT WAS REPORTED ON THE NEWS. I WAS NOT SURE IF THE CAR WAS SKIDDING THE FIRST TIME I EXPERIENCED IT, I WAS GOING SLOWLY AND BRAKED OVER A SLIPPERY PATCH AND THE CAR LURCHED BEFORE BRAKING, BUT THEN IT HAPPENED AGAIN OVER A ROUGH SURFACE. WHEN I REPORTED THIS TO THE SERVICE DEPARTMENT OF MY DEALER, CONICELLI TOYOTA OF SPRINGFIELD, PA, I WAS TOLD THAT NO RECALL HAD BEEN ANNOUNCED, NO OTHER CONCERN OR CARE WAS GIVEN TO ME AT THAT TIME. I DID ASK FOR THE CONTACT INFORMATION OF THE COMPANY AND WAS GIVEN AN 800 NUMBER AND THE WEBSITE. I TRIED CALLING THE CUSTOMER SERVICE LINE OF TOYOTA TWICE TO REPORT MY EXPERIENCE, AND WAS ON HOLD FOR OVER 10 MINUTES BEFORE HANGING UP WITHOUT BEING ABLE TO LEAVE A MESSAGE. I CONTACTED MY DEALER AGAIN AND SPOKE WITH THE CUSTOMER RELATIONS MANAGER, I ASKED THAT THEY REPORT MY EXPERIENCE TO YOU AND THAT THEY WORK TO ADVOCATE FOR A SOLUTION FOR THE BRAKE ISSUE. I AM AWAITING A RESPONSE FROM THEM. I AGAIN TRIED THE 800 NUMBER WITHOUT SUCCESS AND THEN ACCESSED YOUR WEBSITE. I WAS UNABLE TO LOCATE A PLACE TO SEND OR POST MY COMMENT/CONCERN, SO I WROTE THIS LETTER. PLEASE ADD ME TO THE 210 COMPLAINTS REPORTED FOR THE PRIUS BRAKING PROBLEM. I AM DEEPLY CONCERNED THAT TOYOTA 'FIXED' THE PROBLEM ON THE PRODUCTION LINE BUT WAS NOT PROACTIVE IN FINDING A CORRECTION FOR THE MODELS PRODUCED BEFORE JANUARY 2010. I WILL BE CONTACTING MY LAWYER AND OTHER AUTHORITIES ABOUT THIS ISSUE. MY SAFETY AND THE SAFETY OF MY FAMILY AND THOSE THAT SHARE THE ROAD WITH ME ARE OF UTMOST IMPORTANCE TO ME. I AM CONCERNED THAT THEY ARE NOT OF THE UTMOST CONCERN OF TOYOTA, WHO WOULD LEAVE US ALL AT RISK UNLESS PUBLIC PRESSURE IS BROUGHT TO BEAR. . [XXX] *TR

I OWN A 2010 PRIUS. I NOTICE THAT ON MANY OCCASIONS, THE WARNING LAMP ON THE DASHBOARD FOR THE ANTI-SKID SYSTEM COMES ON VERY EASILY, WHEN THE CAR IS NOT IN ANY DANGER WHATSOEVER OF SKIDDING, AND THAT IT SOMETIMES COMES ON WHEN THE CAR IS ACTUALLY AT A STOP. I HAVE ALSO NOTICED THAT WHEN DRIVING ON UNEVEN PAVEMENT, AT MODERATE SPEEDS OF ABOUT 30 MPH, THE BRAKES DO NOT FEEL RELIABLE, AND THAT SOMETIMES THEY FEEL VERY SLOPPY: SLOW TO REACT AND VERY SOFT IN THEIR IMPACT. I HAVE BEEN DRIVING EARLIER MODEL PRIUS CARS FOR SEVERAL YEARS AND DID NOT NOTICE THIS SAME PROBLEM BEFORE I STARTED DRIVING MY 2010 PRIUS. I AM NOT CONFIDENT ABOUT THE BRAKE SYSTEM AND FEEL RELUCTANT TO DRIVE THE CAR, EXCEPT AT VERY LOW SPEEDS.

Mileage: 1,500

PURCHASED 2010 PRIUS V APPORX. MID-JUNE. DRVING IN FIRST WK OF OWNERSHIP, OBSERVED BREAK PROBLEM. VEHCILE HAD APPROX. 50 MILES ON. DRINING 25-30 MPH ON STRAIGHT, SMOOTH, BLACKTOP ROAD ON A SUNNY, NICE DAY. A CAR BACKED OUT OF A 45 DEG PARKING SPOT WITHOUT WARNING, I HAD TO SLAMP ON BREAKS AT THE SAME TIME THE GAS/ELECTRIC MOTORS WERE SWITCHING. THE BREAK PEDAL LOST FEELING THAT IT HAD PRESSURE UNTIL I PUSHED THE BREAK PEDAL ANOTHER 2 INCHES MORE TO FEEL PRESSURE AND THAT THE BREAKS WERE GRABBING. I DID NOT REPORT THIS IN JUNE, DUE TO I THOUGHT I WAS IMAGINING THINGS DUE TO THE EMERGENCY STOP TOOK MY ATTENTION TO SOME DEGREE. I WAS A SERVICE MANAGER FOR CHRYSLER YEARS AGO, SO I AM VERY FAMILIAR WITH VEHCILE MECHANICAL SYSTEMS AND I HAVE PURCHSED APPROXIMATELY 25 NEW VEHCILES IN MY LIFETIME.

THE BRAKES ON MY 2010 PRIUS DID NOT ENGAGE TWO TIMES WHILE DRIVING IN SNOWY CONDITIONS THIS WINTER. I ALMOST CRASHED INTO A CAR BOTH TIMES.

Mileage: 5,000

BRAKES DISENGAGE MOMENTARILY WHEN BRAKING ON A ROUGH OR RIPPLED SURFACE. IT GIVES THE FEELING THE VEHICLE IS BEING ACCELERATED. UNCONTROLLED TRAVEL DISTANCE CAN BE LENGTHLY. I HAVE EXPERIENCED FOUR SUCH INSTANCES.

Mileage: 5,000

THE BRAKES ON MY PRIUS HAVE FAILED NUMEROUS TIMES OVER 7 MONTHS IN BOTH CITY AND RURAL DRIVING CONDITIONS. WHEN BRAKE FAILURE OCCURS, THE PRIUS BRAKES NOT ONLY DISENGAGE (FAIL) BUT THE CAR SEEMS TO LUNGE FORWARD. IT'S AS IF I AM BRAKING WITH MY FOOT ON THE GAS PEDAL AND THEN LET UP ON THE BRAKE WHILE THE GAS PEDAL IS STILL DEPRESSED. IT IS NOT A SAFE VEHICLE. I HAVE GREAT CONCERN FOR MY SAFETY AND THE SAFETY OF MY FAMILY AND OTHERS, PARTICULARLY PEDESTRIAN SAFETY AT INTERSECTIONS.

I WAS DRIVING DOWN A HILL THAT HAS A SLIGHTLY UNEVEN SURFACE AND WAS A BIT ICY AND WHEN APPLYING THE BRAKE IN MY PRIUS, MY CAR SPED UP SLIGHTLY WHEN IT HIT THE UNEVEN SURFACE AND SEEMINGLY JUMPED FASTER BEFORE THE BRAKES KICKED IN AND BROUGHT MY CAR TO A STOP. THIS HAS HAPPENED TWICE ON DIFFERENT ROADS, BOTH OF THE ROAD SURFACES BEING SLIGHTLY UNEVEN. NOTHING HAS BEEN DONE TO CORRECT THIS PROBLEM, WHEN I CALLED TOYOTA THEY TOLD ME THAT THERE WAS NOTHING THEY COULD DO.

Mileage: 5,100

THE BRAKES ON MY 2010 TOYOTA PRIUS AT TIMES DO NOT ENGAGE IMMEDIATELY. IT MAY BE NECESSARY AT THOSE TIMES TO DEPRESS THE BRAKE PEDAL BY 1/3RD BEFORE BRAKING BEGINS. THERE IS A SIMILAR DELAY WHEN BRAKING IS USED TO TURN OFF CRUISE CONTROL. NEITHER OF THESE HAVE CAUSED AN ACCIDENT, BUT IN BOTH CASES THERE IS SOME RISK.

MY 2010 TOYOTA PRIUS, PURCHASED 12/28/09, HAS BRIEFLY LURCHED FORWARD ON MULTIPLE OCCASIONS WHEN I WAS BRAKING AND CROSSED A BUMP IN THE ROAD. I AM REPORTING ONE DATE BELOW, BUT THE BRIEF BRAKE FAILURE HAS RECURRED REPEATEDLY, ALWAYS AT THE SAME SPOT ON THE ROAD.

Mileage: 649

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 ON AT LEAST 4 OCCASIONS EXPERIENCED THE BRAKING ISSUE (THAT IS BEING INVESTIGATED) ON MY 2010 PRIUS. IT HAPPENS WHEN I GO OVER RAILROAD TRACKS, OR HIT A POTHOLE. PLEASE ADD MY COMPLAINT TO THE OTHERS THAT REPORT SIMILAR PROBLEMS.

AS I BRAKED TO MAKE A RIGHT TURN AT AN INTERSECTION, MY TWO WEEK OLD 2010 TOYOTA PRIUS STOPPED BRAKING WHEN I HIT A SECTION OF THE ROADBED THAT HAD SOME WINTER DAMAGE TO IT AND THE CAR'S ANTI-LOCK BRAKES ATTEMPTED TO CUT IN. IT FELT LIKE THE CAR SURGED FORWARD, BUT I UNDERSTAND IT WAS JUST A SUDDEN LOSS OF BRAKING AS THE TRANSFER BETWEEN THE DIFFERENT BRAKING MECHANISMS OCCURRED. SINCE I WAS TURNING ONTO A HIGHWAY SERVICE ROAD DURING RUSH HOUR, I FELT THE DELAY WAS A DANGER TO ME AND THE OCCUPANTS OF MY VEHICLE.

I HAVE PURCHASED A 2010 TOYOTA PRIUS, AND NEVER NOTICED ANY PROBLEM WITH MY BRAKING, UNTIL 1/22/10. I WAS DRIVING OVER A SECTION OF ROAD, THAT WAS UNEVEN WHERE A BRIDGE MEETS THE ROAD. I WAS BRAKING FOR THE STOPLIGHT AHEAD THAT WAS RED AND CARS WERE WAITING IN THE LINE. WHEN I APPLIED THE BRAKES AT ABOUT 10 MPH, AND HIT THE UNEVEN ROAD SECTION, THE CAR SEEMED LIKE IT LOST BRAKING, FOR AN INSTANT. I HAD TO PUSH HARDER ON THE BRAKE PEDAL TO ASSURE A STOP. I HAVE SINCE DRIVEN THAT SAME SECTION OF ROAD TO REPLICATE THE PROBLEM, AND IT HAD REPEATED ITSELF, BUT NOT ON EVERY OCCASION. IT APPEARS THAT THERE IS SOME ISSUE WITH THE HYBRID BRAKE SYSTEM...BETWEEN REGENERATION AND FRICTION BUT NOT SURE WHAT THE ISSUE IS. I ONLY HAVE 3800 MILES ON THE CAR SO HAVE NOT CALLED THE DEALER FOR SERVICE YET. WILL PLAN TO DO THAT IF IT CAN WAIT UNTIL THE FIRST 5,000 MILE SERVICE. *CN

OUR 2010 TOYOTA PRIUS IS EXPERIENCING PERIODIC, TEMPORARY BRAKE FAILURE/UNINTENDED ACCELERATION. MY WIFE IS THE PRIMARY DRIVER AND STATES THAT ON 4-5 OCCASIONS OVER THE PAST 9 MONTHS, WHEN BRAKING OVER UNEVEN SURFACES AT SPEEDS OF 10-30 MPH, THERE CAN BE A TEMPORARY PERIOD OF UNINTENDED ACCELERATION LASTING 1-2 SECONDS. *CN

Mileage: 7,000

WHILE SLOWLY DECELERATING USING THE REGENERATIVE BRAKES, THE REGENERATIVE BRAKES TURN OFF OCCASIONALLY AT LOW SPEEDS (5-10 MPH). THERE IS A VERY SHORT (<1 SECOND) BURST OF FORWARD MOVEMENT BEFORE THE ACTUAL BRAKES ACTIVATE. DURING THIS WHOLE TIME THE BRAKE PEDAL IS CONSISTENTLY DEPRESSED. THIS BURST FORWARD DOES WHIP THE DRIVER BACK INTO THE SEAT A BIT DUE TO THE UNEXPECTED NATURE OF THIS EVENT. THIS HAS PROBABLY OCCURRED ABOUT 5 TIMES IN THE PAST 2.5 MONTHS SINCE I PURCHASED THE VEHICLE. *CN

Mileage: 2,000

AFTER OWNING THE CAR FOR 1 MONTH, I HAVE NOTICED THAT ON OCCASION, WHEN I PRESS THE BRAKES, THE CAR WILL AUTOMATICALLY ACCELERATE FOR A SECOND BEFORE BREAKING. THIS DOES NOT HAPPEN EVERY TIME, BUT IT DOES HAPPEN A FEW TIMES DAY. I HAVE NO WAY OF FIGURING OUT WHAT COULD BE CONTRIBUTING FACTORS SINCE IT JUST HAPPENS WHEN I AM BRAKING JUST BEFORE IT COMPLETELY STOPS, NO MATTER WHAT SPEED I AM DRIVING. *CN

WHEN BRAKING WHILE GOING OVER BUMPS, THE CAR LURCHES FORWARD AND DOESN'T SEEM TO GRAB UNTIL AFTER THE BUMP. IT IS ESPECIALLY NOTICEABLE WHEN EXITING A HIGH SPEED ROAD ONTO A DECELRATION LANE. IT HAS BEEN ONGOING SINCE PURCHASING THE VEHICLE. I HAVE MADE ADJUSTMENTS IN OPERATING THE VEHICLE TO MINIMIZE THE NUMBER OF OCCURENCES, BUT CANNOT ALWAYS FORESEE THE BUMPS OR RIDGES IN ROAD SURFACES THAT PRECIPITATE THE INCIDENT. *CN

CAR IN FRONT OF ME PULLED AWAY AT THE SAME TIME (FORTUNATELY) AS MY CAR LURCHED FORWARD; I DIDN'T FEEL IT WAS GOING TO STOP; WHEN I THEN PROCEEDED CAR MADE HORRIBLE NOISES...SOUNDED I THOUGHT BOTTOM WAS GOING TO FALL OUT. HAVE EXPERIENCED THE SAME "NOT GOING TO STOP" FEELING A SECOND TIME SINCE. WHAT FOLLOWED? CALLED DEALERSHIP IMMEDIATELY; THEY SUGGESTED I COME IN FOR BRAKE CHECK, WHICH I DID FOLLOWING DAY. TOLD IT WAS GOING TO COST $125; WE DISCUSSED LIKELIHOOD THAT PROBLEM PROBABLY WOULDN'T HAPPEN FOR THE MECHANIC, I DECIDED AGAINST SPENDING MONEY FOR BRAKE CHECK UP WHEN SERVICE DEPT. TOLD ME IT WAS "JUST THE WAY PRIUS' ABS BRAKES WORK." WHEN I ASKED ABOUT THE NEWS REPORTS I'D HEARD ABOUT THIS BRAKING PROBLEM THEY DIDN'T KNOW ANYTHING ABOUT IT, POINTED TO ABSENCE OF INFO ON TOYOTA'S WEBSITE FOR SERVICE DEPARTMENTS AND SAID MEDIA OFTEN BLOWS THINGS OUT OF PROPORTION. CALLED TOYOTA CORP AND CASE MANAGER THAT RETURNED CALL TO ME HAD NO INFORMATION ABOUT MEDIA REPORTS I REFERRED TO. *TW

SINCE PURCHASING MY 2010 TOYOTA PRIUS, I HAVE HAD SERIOUS ISSUES AND SAFETY CONCERNS WITH THE BRAKING SYSTEM. WHEN YOU BRAKE AND HIT A BUMP OR POTHOLE OR LARGE DIP, THE BRAKE CUT OUT AND THE CAR IS NOT CONTROLLABLE UNTIL A FEW MOMENTS LATER. I REPORTED THIS TO THE DEALER AND WAS ASSURED IT WAS PERFORMING AS INTENDED AND NORMAL FOR AN ANTI-LOCK SYSTEM. HAVING USED ANTI-LOCK BRAKES FOR NEARLY 20 YEARS, I KNOW THIS TO NOT BE THE CASE AND STATED THIS. I NOW UNDERSTAND THIS PROBLEM IS WIDESPREAD. MY MOST RECENT EMAIL TO TOYOTA IS ATTACHED: DATE: FEBRUARY 7, 2010 11:46:13 AM EST DEAR I RECEIVED YOUR EMAIL ADDRESS THIS MORNING AND FELT I SHOULD FORWARD ON MY EARLIER EMAILS (REGARDING BRAKING PROBLEMS WITH MY 2010 PRIUS) TO COLONIAL TOYOTA DIRECTLY TO YOU - PLEASE FIND THEM BELOW. I UNDERSTAND THAT LATE FRIDAY TOYOTA CORPORATION ADVISED DEALERS THAT CORPORATE WOULD ANNOUNCE A FIX EARLY THIS WEEK. I HONESTLY WOULD HAVE PREFERRED TO HAVE LEARNED THIS FROM COLONIAL, THAN FROM THE NY TIMES. AS I EXPRESSED DURING MY SALES EXPERIENCE AND TROUBLES WITH CASH FOR CLUNKER PROGRAM - I UNDERSTAND THERE ARE CERTAIN THINGS AS A DEALER THAT YOU ARE NOT IN CONTROL OF, BUT I EXPECT AND WOULD APPRECIATE CLEAR AND TIMELY COMMUNICATION. MOREOVER, GIVEN THE SERIOUSNESS OF THIS AS A SAFETY CONCERN, I AM CONCERNED THAT THE SERVICE DEPARTMENT DID NOT AT LEAST OFFERING TO HELP LOOK INTO MY BRAKING ISSUE WHEN I VERBALLY REPORTED IT DURING SERVICE. INSTEAD, I WAS ASSURED IT WAS NORMAL FOR ANTI-LOCK BRAKES AND MY CLEAR STATEMENT THAT IT WAS SOMETHING I HAD NEVER ENCOUNTERED BEFORE, DESPITE OWNING ANTI-LOCK EQUIPPED CARS FOR THE PAST 19 YEARS WAS DISMISSED. I WOULD LIKE TO REITERATE MY REQUEST BELOW REGARDING BRINGING MY VEHICLE IN IMMEDIATELY TO FIX THE ISSUE (AND RELATED DAMAGE) AS SOON AS YOU ABLE TO AND PROVIDING A LOANER AT TOYOTA'S EXPENSE. I LOOK FORWARD TO HEARING FROM YOU AS SOON AS POSSIBLE. *TW

THIS IS THE SECOND TIME MY CAR HAS HIT A POTHOLE IN THE ROAD AND THE BRAKES STOPPED WORKING. THE FIRST TIME I THOUGHT IT WAS JUST ME, BUT THE SECOND TIME I REALIZED IT WAS REALLY HAPPENING AND SCARY. I WAS HEADED SOUTHBOUND ON ROWENA BLVD IN LOS ANGELES, WAS STARTING MY DECELERATION WHEN I HIT THIS POT HOLE ON THE RIGHT SIDE OF THE ROAD. FOR ABOUT 2 SECONDS MY CAR STOPPED DECELERATING AND I COULD FEEL NO POWER ON THE BRAKE PADS, THEN SUDDENLY THE BRAKE POWER RETURNED. *TW

I TOOK IT TO THE DEALER DECEMBER 14, 2009 WITH THE FOLLOWING COMPLAINT: REAR BRAKES WILL LOCK UP AND SLIDE WHEN TURNING CORNERS, THEY WILL ALSO LOCK UP WHEN BACKING SLOWLY. THE FIRST TIME THEY DID THAT I THOUGHT I HAD HIT SOMETHING. THE DEALER KEPT THE CAR OVERNIGHT. THE TECHNICIAN SAID HE COULD NOT DUPLICATE THE ACTION AND THE SHOP MGR. SPOKE WITH TOYOTA TECHNICIAN AND WAS TOLD THERE WERE NO KNOWN CONCERNS AT THAT TIME. SINCE THEN I HAVE CALLED SEVERAL TIMES ABOUT THE PROBLEM BUT NO ONE WOULD TAKE ME SERIOUS. *TW

I OWN A 2010 TOYOTA PRIUS WHICH I PURCHASED IN AUGUST 2009. WHEN I DRIVE DOWN A BUMPY HILL NEAR MY HOME, THE BRAKES TEMPORARILY FAIL TO HOLD IF I AM BRAKING WHILE GOING OVER THE BUMPS THEMSELVES.

THE CAR SURGES FORWARD BEFORE IT STOPS. I TOOK THE CAR TO THE DEALERSHIP IN LATE NOVEMBER-DECEMBER FOR THE PROBLEM THEY TELL ME THE BRAKES FUNCTION PROPERLY. I HAVE SINCE SCHEDULED ANOTHER APPOINTMENT, THEY DID NOT SEEM TO CARE THAT A BRAKE ANNOUNCEMENT HAD BEEN MADE ON MY PRIUS. I EXPLAINED TO THEM THAT IF THEY DID NOT WANT TO FIX OR ADDRESS MY PROBLEM, THAT WHEN I HIT SOMEONE BECAUSE MY CAR DOES NOT STOP AND SURGES FORWARD, I WILL SUE TOYOTA.

EXPERIENCED LACK OF BRAKING WHEN MY 2010 PRIUS WAS GOING OVER BUMPY TERRAIN. I WAS PRESSING ON THE BRAKE AS I WAS APPROACHING AN INTERSECTION, AND NO BRAKING WAS OCCURRING UNTIL THE CAR REACHED SMOOTH GROUND AGAIN. INSTEAD IT FELT LIKE I WAS SKIDDING, AND THE BRAKE PEDAL JUST VIBRATED BACK AT ME. I CAN CONFIRM THAT THE PROBLEM BEING REPORTED IN THE NEWS MEDIA IN JAPAN, IS IN FACT, A REAL PROBLEM. WHEN I HEARD ABOUT IT ON THE NEWS, I REALIZED, HEY, I EXPERIENCED THAT. I WOULD ENCOURAGE A RECALL. IT IS A LEGITIMATE PROBLEM THAT DOES INDEED SOMETIMES OCCUR IN THE SITUATION I DESCRIBED. IT IS SCARY. *TW

I THOUGHT IT WAS JUST THE NEW CAR WHICH I HAVE NOT GOTTEN USED TO AND THAT IT NEEDS TO BE BROKEN IN. I HAVE NOT DRIVEN THE CAR SINCE LATE DECEMBER DUE TO FEAR OF PROBLEMS IN THE RAIN.

2010 TOYOTA PRIUS. THIS WEEK, TOYOTA IS SUPPOSED TO ANNOUNCE WHETHER THE 2010 PRIUS WILL BE RECALLED FOR PROBLEMS WITH ITS BRAKING SYSTEM. I BROUGHT MY PRIUS ON SEPTEMBER 4, 2009 FROM SAN FRANCISCO TOYOTA. I HAVE THE PROBLEM THAT HAS BEEN DESCRIBED IN THE MEDIA: THOUGH I HAVE NOT DRIVEN IT IN RAINY CONDITIONS, THE BRAKING SYSTEM FAILS WHEN I HIT A POT HOLE WHILE APPLYING THE BRAKES. THERE IS A HILL NEAR MY HOME THAT I DRIVE MOST EVERY DAY. IT HAPPENS IN THE SAME PLACE EVERY TIME: I AM HEADED DOWNHILL TOWARD A STOP SIGN; I HIT THE POT HOLE AND FOR A SECOND MY CAR FEELS AS THOUGH IT WERE HYDRO PLANING--I HAVE ABSOLUTELY NO CONTROL. I DIDN'T THINK TO COMPLAIN ABOUT THIS BEFORE I BEGAN HEARING THE NEWS. I DON'T DRIVE VERY MUCH IN THE CITY AND IT WAS ONLY IN THIS ONE SPECIFIC PLACE THAT THE BRAKE SYSTEM SEEMED TO FAIL. BUT IT IS TERRIFYING TO FEEL THAT YOUR CAR IS OUT OF CONTROL. IF I DROVE MY PRIUS MORE I AM CERTAIN I WOULD BE EXPERIENCING THIS DESIGN FLAW MORE. I ENCOURAGE NHTSA TO BRING ITS REGULATORY WEIGHT TO BEAR TO FORCE TOYOTA TO FIX THIS PROBLEM--WHICH IT HAS FOR 2010 PRIUS'S SOLD AFTER JANUARY 2010. I WOULD LIKE THE SAME SAFETY MEASURES TAKEN FOR THOSE OF US WHO HAVE DEFECTIVE AND POTENTIALLY DANGEROUS VEHICLES, BUT WHO BOUGHT OUR PRIUS'S BEFORE JANUARY 2010. *TW

THE BRAKES ON MY 2010 PRIUS HAVE A PROBLEM WHEN GOING SLOWLY OVER UNEVEN, BUMPY ROAD CONDITIONS. THE CAR SEEMS TO LURCH FORWARD DURING THE BRAKING SEQUENCE. IT IS VERY STARTLING. LUCKILY NO ONE HAS BEEN IN FORNT OF ME, CLOSE ENOUGH TO MAKE CONTACT. IT HAS HAPPENED 5 TIMES. I CANNOT PREDICT WHEN IT WILL OCCUR. WHEN I FIRST TOLD THE SERVICE DEPT AT DEALERSHIP, WITHIN 2 WEEKS OF OWNING CAR, THEY SIAD IT'S JUST SOMETHING TO GET USED TO WITH THE BRAKING SENSOR OR SOMETHIONG AND IT ISN'T ACTUALLY ACCELERATING FORWARD. I MENTIONED IT AGAIN LAST WEEK AFTER THE ISSUES WITH THE OTHER CARS ACCELERATORS, AND THE SERVICE DEPT SAID I HAVE TO REPLICATE IT WITH THEM, TO ADDRESS IT. I CALLED THEM AFTER INFO WAS BROADCAST ON THE RADIO, AND THEY SAID THEY HAD NOT HEARD ANYTHING. NOW I HEAR IN THE NEWS THAT THEY KNEW OF THIS PROBLEM AND ALMOST EXACTLY DESCRIBE IT AS I EXPERIENCE IT. I DRIVE OVER THIS TYPE OF ROAD DAILY, AND AM TRYING TO AVOID AS MUCH AS POSSIBLE. *CN

TOYOTA PRIUS 2010 - BREAKS FAILED TO STOP CAR ON 3 SEPARATE OCCASIONS DURING THE PAST MONTH. EACH OCCURRENCE WAS AT AN INTERSECTION (ROADS EACH TIME WERE PLOWED FOR SNOW, BUT STILL A BIT SLICK). THE CAR EVENTUALLY STOPPED DUE TO THE VEHICLE SLOWING DOWN, BUT STILL NOT BREAKING. ONE OCCURRENCE WAS AT AN INTERSECTION WHERE THE CAR DID NOT BREAK AT A RED LIGHT AND I QUICKLY TURNED THE WHEEL TO THE RIGHT TO PROCEED ONTO A SIDE ROAD. I HAVE CALLED THE SERVICE DEPARTMENT AT THE TOYOTA DEALERSHIP (WHERE THE CAR WAS PURCHASED LAST FALL), AND HAVE NOT RECEIVED A RESPONSE. *CN

ON SEVERAL OCCASIONS MY 2010 PRIUS HAS FAILED TO STOP IMMEDIATELY WHEN I HAVE APPLIED THE BRAKE AT SLOW SPEEDS. THIS HAS OCCURRED WHILE ON ICE SURFACES AS WELL AS CLEAR SURFACES. THERE IS JUST A FRACTION OF A SECOND DELAY BEFORE THE BRAKES TAKE HOLD. FORTUNATELY THERE HAS NOT YET BEEN AN ACCIDENT BUT IF I WERE TO HAVE HAD LESS SPACE BETWEEN ME AND THE CAR AHEAD, THERE WOULD HAVE BEEN A CRASH. *CN

HALFWAY DOWN A HILL IN THIS VERMONT VILLAGE IS A RIGHT TURN THAT GOES UPHILL. I HAVE DRIVEN THIS IS IN WINTER WEATHER IN MANY DIFFERENT VEHICLES FOR OVER 40 YEARS. ON THIS DAY THERE WAS SNOW ON THE ROAD SO I WAS DRIVING SLOWLY GOING DOWN THE HILL AND WAS GOING TO MAKE THE RIGHT HAND TURN BUT WHEN I APPLIED THE BRAKES THEY REACTED UNLIKE ANY OTHER CAR I HAVE DRIVEN IN THOSE CONDITIONS AND JUST SEEMED TO CAUSE ME TO SLIDE INSTEAD OF SLOWING DOWN. AT THAT POINT I DECIDED NOT TO TURN AND CONTINUED CAREFULLY DOWN THE HILL. FORTUNATELY THERE WERE NO VEHICLES IN FRONT OF ME OR I FELT I MIGHT HAVE SLID INTO THEM. LATER THAT WEEK I CALLED AND TALKED TO THE TOYOTA SERVICE MANAGER WHERE I HAD BOUGHT THE CAR. HE SAID HE WASN'T AWARE OF ANY PROBLEM WITH BRAKES, THAT HE HAD A PRIUS, ALTHOUGH AN OLDER MODEL, AND HADN'T HAD ANY PROBLEM. HE HAD HEARD FROM ONE OTHER PERSON WITH A BRAKING COMPLAINT ON THE 2010 MODEL. I ASKED HIM TO INFORM ME IF HE FOUND OUT ANYTHING BUT I NEVER HEARD FROM HIM. THE CONDITION WAS SERIOUS ENOUGH FROM MY POINT OF VIEW THAT SINCE I HAVE A SECOND CAR I HAVE NOT USED THE PRIUS IN INCLEMENT WEATHER. I WOULD CONSIDER THIS, IN LIGHT OF RECENT DISCLOSURES, TO BE A VERY SERIOUS AND UNSAFE CONDITION TO PUT ME, ME FAMILY AND OTHERS ON THE HIGHWAY AT RISK AND WOULD HOPE THAT A RECALL AND RESOLUTION TO THIS PROBLEM WOULD BE QUICK AND FORTHCOMING. *CN

WHILE TRAVELING OVER A SPEED BUMP AND APPLYING BRAKES, BRAKES MALFUNCTION FOR A PERIOD OF TIME.

I WAS DRIVING MY 2010 PRIUS APPROXIMATELY 20 MPH ON AN ICY ROAD. BECAUSE IT WAS ICY, I STARTED BRAKING VERY EARLY BEFORE COMING TO A STOP SIGN. THERE WAS NO RESPONSE FROM THE BRAKES AT ALL. I BLEW THROUGH THE STOP SIGN OUT ONTO A 40 MPH ROAD. I WAS ONLY ABLE TO AVOID A COLLISION BY STEERING AWAY FROM CARS. I APPLIED THE BRAKES THE ENTIRE TIME, WHICH WAS SEVERAL SECONDS AND THE BRAKES NEVER ENGAGED. THE NEXT TIME I USED THE BRAKES, THEY WORKED. INITIALLY I THOUGHT THAT THE REASON THE CAR DID NOT SLOW DOWN WAS BECAUSE IT DID NOT HAVE ANY TRACTION DUE TO THE ICY CONDITIONS. BUT AFTER THINKING ABOUT IT, I DID HAVE TRACTION BECAUSE I WAS ABLE TO STEER QUITE WELL AND SUDDENLY CHANGE DIRECTIONS WITHOUT ANY SLIPPING AT ALL. THIS DID NOT MAKE SENSE TO ME UNTIL I READ ABOUT THE BRAKING PROBLEMS. MY HUSBAND HAS EXPERIENCED THE CAR LURCHING FORWARD WHEN APPLYING THE BRAKES ON A SLIPPERY OR UNEVEN SURFACE MANY TIMES. HE APPLIES THE BRAKE AND THE CAR LURCHES FORWARD BEFORE THE BRAKES ENGAGE. *CN

THIS HAS OCCURRED SIX TIMES SINCE I PURCHASED THE VEHICLE IN SEPTEMBER OF 2009. I TOOK THE CAR TO TOYOTA OF SANTA MONICA ON FEBRUARY 5,2010. THEY RAN A DIAGNOSTIC TEST AND CONCLUDED THAT NOTHING WAS FAULTY WITHIN THE BRAKING SYSTEM. THIS IS THE SAME DAY EVERY NEWS ORGANIZATION IN THE WORLD WAS REPORTING THAT TOYOTA ADMITTED THERE IS A SOFTWARE PROBLEM IN THE ABS BRAKING SYSTEM AND WAS REPAIRED ON 2010 PRIUS MODELS BUILT FROM JANUARY 2010. *CN

1) WHILE DRIVING MY NEW 2010 TOYOTA PRIUS STRAIGHT AHEAD AT APPROXIMATELY 10-15 MPH ON A DRY, SUNNY DAY, I HIT THE BRAKES HARD TO STOP AT A RED LIGHT. THE CAR SKIDDED LOUDLY ENOUGH THAT SEVERAL BYSTANDERS LOOKED AT ME. THIS WAS CLEARLY A FAILURE OF THE ANTI-LOCK BRAKING SYSTEM. I RECENTLY BROUGHT THE VEHICLE TO MY TOYOTA DEALER (TOYOTA SANTA CRUZ), WHICH INSPECTED THE BRAKES AND DECLARED THEM TO BE FINE. THIS PROBLEM HAS NOT RECURRED, THOUGH I HAVE NOT HAD TO APPLY THE BRAKES IN SUCH A STRONG MANNER SINCE THAT ONE INCIDENT. 2) ON TWO SEPARATE OCCASIONS, WHILE DRIVING THE SAME PRIUS AT VERY SLOW SPEEDS (PERHAPS 5 MPH) SHORTLY AFTER STARTING THE CAR, MY WIFE GENTLY APPLIED THE BRAKES; THE VEHICLE JERKED ALMOST TO A STOP. IN OTHER WORDS, A GENTLE APPLICATION OF THE BRAKE PEDAL LED TO A VERY RAPID, JERKY, STOP AS IF SHE HAD SLAMMED ON THE BRAKES. *CN

I OWN A 2010 TOYOTA PRIUS AND FREQUENTLY (~1 X WEEK) EXPERIENCE A BRAKING PROBLEM AS BEING REPORTED BY THE MEDIA. IF, WHILE I AM BRAKING, THE CAR GOES OVER A BUMP, POT-HOLE, OR WAVY PAVEMENT, THE CAR FEELS LIKE IT ISN'T BRAKING, AS IF THE WHEEL IS OFF THE GROUND OR SLIDING ON ICE. IT ONLY OCCURS WHILE THE CAR IS BEING BUMPED, SO USUALLY IT IS ONLY LASTS A MATTER OF A FEW FEET. I HOPE THIS HELPS YOU IDENTIFY THE PROBLEM AND DETERMINE A COURSE OF ACTION. *CN

WHILE APPLYING THE BRAKES TO SLOW DOWN TO GO AROUND A CURVE THAT ALSO GOES DOWNHILL, MY 2010 TOYOTA PRIUS SEEMS TO SPEED UP FOR A FEW SECONDS IN THE MIDST OF THE TURN. I CAN'T TELL IF THIS IS THE BRAKING SYSTEM FAILING OR THE ACCELERATOR KICKING IN. IT'S NOT CENTRIFUGAL FORCE, BECAUSE THERE IS A CLEAR SURGE FORWARD. THIS HAPPENS PRETTY REGULARLY, AS THIS IS A MANEUVER THAT I MAKE REGULARLY ON MY WAY HOME. I PUT IN AN ARBITRARY DATE BELOW, BECAUSE IT HAS HAPPENED MANY TIMES. I NOTICE THIS HAPPENING AT OTHER TIMES TOO, BUT I DON'T HAVE A CONSISTENT RECORD OF WHEN AND WHERE IT HAPPENS. *CN

SINCE PURCHASE IN OCTOBER 2009, I HAVE EXPERIENCED OCCASIONAL PROBLEMS WITH THE BRAKES ON MY 2010 TOYOTA PRIUS. SPORADICALLY, WHEN I APPLY THE BRAKES TO SLOW DOWN GOING DOWN A SLIGHT INCLINE OR STOPPING AT LIGHTS OR INTERSECTION, I FEEL A MOMENTARY LAG BEFORE THE BRAKES ACTUALLY FUNCTION. THE LAG IS NOTICEABLE AND SIMILAR TO FEELING AIRBORNE OR SLIPPING CAUSING ME TO FRANTICALLY PUSH DOWN HARDER ON THE BRAKE PEDAL THAN USUAL. THIS HAS RECURRED PERHAPS 10 DIFFERENT TIMES I ALSO HAD ONE INCIDENT WHEN THE BRAKE SEEMED TO LOCK WHEN THE GEAR WAS IN REVERSE AND I WAS BEGINNING TO BACK OUT OF A PARKING SPACE. PLEASE NOTE THE DATE OF INCIDENT AND MPH IS ONLY AN ESTIMATE. *CN

WHILE SLOWING DOWN (FOOT ON THE BRAKE) FOR A LIGHT OR ROAD BUMP, THE CAR SUDDENLY ACCELERATES UNTIL I PRESS HARDER ON THE BRAKE. THIS HAS OCCURRED ABOUT 10 TIMES SINCE I PURCHASED THE CAR SUMMER OF 2009. NO ACCIDENT BUT ALMOST REAR-ENDED THE CAR IN FRONT OF ME SEVERAL TIMES. BROUGHT TO TOYOTA AND TOLD NOTHING WAS WRONG AND I WASN'T USED TO THE ABS SYSTEM. THIS CAN'T EXPLAIN THE SUDDEN ACCELERATION AND NEAR MISS ACCIDENTS. *CN

ALSO, THE TRACTION CONTROL SYSTEM LIGHT ("SLIPPERY" WARNING) SOMETIMES BEEPS/FLASHES EVEN WHEN I AM SITTING STILL ON DRY LEVEL PAVEMENT, ESPECIALLY IF I DEPRESS THE BRAKES ALL THE WAY TO THE FLOOR. I HAVE NOT YET EXPERIENCED ANY LIFE OR PROPERTY LOSS AS A RESULT AND AM PROVIDING THIS INFORMATION ON A PURELY FYI BASIS AS YOU TRY TO FIGURE OUT ISSUES WITH 2010 PRIUS BRAKES.

2010 TOYOTA PRIUS THE BRAKING SYSTEM DOES NOT WORK WHEN THE BRAKES ARE APPLIED OVER BUMPY OR ROUGH ROADS. OCCURS EVERYTIME THE BRAKES ARE APPLIED AT A PARTICULAR INTERSECTION.

I NOTICED THE PROBLEM, IT RAISED SOME CONCERNS, BUT RECENT ARTICLES HAVE INDICATED THIS IS A SEVERE ISSUE. *TR

I OWN A BRAND NEW 2010 TOYOTA PRIUS WITH APPROXIMATELY 3,000 MILES AT THIS POINT. I HAVE EXPERIENCE ON A NUMBER OF OCCASIONS A COMPLETE LOSS OF BRAKING ABILITY WHEN I FORCEFULLY APPLIED THE BRAKES IN ORDER TO COME TO STOP WHILE TRAVELING OVER A POTHOLE OR A SERIOUS PAVEMENT DEFORMATION. MY WIFE HAS EXPERIENCED THE SAME PROBLEM ON A COUPLE OF INSTANCES TOO. THE LOSS OF BRAKES IS VERY SHORT IN DURATION BUT IS ABSOLUTELY FRIGHTENING SINCE THE CAR TRAVELS QUITE A BIT BEFORE THE BRAKES TAKE EFFECT AGAIN. ON ONE OCCASION THE PRIUS WAS ABOUT ONE QUARTER OF A CAR LENGTH INTO THE INTERSECTION BEFORE IT CAME TO A COMPLETE STOP. THIS HAPPENED WHILE TRAVELING ONLY 35 MPH ON A RESIDENTIAL STREET AND ATTEMPTING TO COME TO A FULL STOP AT AN INTERSECTION. FORTUNATELY NO OTHER CARS WERE TRAVELING THROUGH THE INTERSECTION AT THE TIME. I ATTEMPTED TO CALL TOYOTA ABOUT THIS ISSUE BUT IT IS IMPOSSIBLE TO GET THROUGH TO A LIVE PERSON AT THIS TIME DUE TO THE VOLUME OF CALLS GENERATED BY THE RECALL. *TR

EVENTUALLY AFTER PRESSING VERY HARD ON THE PEDAL THE VEHICLE SLOWS. THE BIGGEST ISSUE IS THIS DOES NOT HAPPEN ALL THE TIME. IT PRESENTS A PROBLEM WHEN IT UNEXPECTEDLY HAPPENS. *TR

WE PURCHASED A 2010 PRIUS IN AUGUST OF 2009 AND HAVE HAD THE FOLLOWING RECURRING ISSUES: 1. LOSS OF BRAKING WHEN SLOWING DOWN OVER ROUGH OR UNEVEN PAVEMENT, GRAVEL, WET LEAVES, SNOW, ICE, CRACKED PAVEMENT, POT HOLES... THE BRAKES ENGAGE FOR A SECOND, AND THEN WE EXPERIENCE NO BRAKING AT ALL FOR NUMBER OF SECONDS. WE TOOK OUR PRIUS INTO JON LANCASTER TOYOTA IN MADISON, WI WHERE WE PURCHASED THE VEHICLE AND TOLD THE MECHANIC OF THE BRAKING ISSUES WE WERE EXPERIENCING . HE CHECKED OUT THE VEHICLE AND SAID HE COULD NOT FIND ANY ISSUES WITH THE BRAKING SYSTEM AND SAID THAT HE HAD NEVER HEARD OF THIS PROBLEM AND NEITHER HAD TOYOTA. THIS LACK OF BRAKING RESULTED IN A REAR END COLLISION IN DECEMBER 2009. MY HUSBAND WAS DRIVING AT VERY LOW SPEED IN TOWN ONE EVENING AND THIS LACK OF BRAKING ISSUE OCCURRED AND HE SLID INTO ANOTHER VEHICLE. MY HUSBAND PUMPED THE BRAKES FOUR TIMES AND EACH TIME THIS DELAY IN BRAKING OCCURRED. THERE WAS NO BRAKING HAPPENING AT ALL. THE CAR WAS SLOWING DOWN FASTER WHEN THE BRAKES WERE NOT APPLIED, THAN WHEN THE BRAKES WERE APPLIED. THERE WAS FRESH SNOW ON THE ROAD. THERE WAS A DANE COUNTY SHERIFF AT THE INTERSECTION AND MY HUSBAND AND THE PERSON HE HIT RAN THE INCIDENT BY THE STATE PATROL WHO AGREED THAT IT WAS APPROPRIATE FOR THE TWO PARTIES INVOLVED IN THE ACCIDENT TO EXCHANGE INSURANCE AND CONTACT INFORMATION AND LEAVE THE SCENE WITHOUT CALLING THE LOCAL POLICE. THERE WAS DAMAGE TO OUR PRIUS FRONT BUMPER, AND TO THE BACK BUMPER OF THE OTHER VEHICLE. 2. OCCASIONALLY WHEN STARTING UP THE PRIUS, THE BRAKE FEELS HARD AND CAN'T BE DEPRESSED ALL THE WAY. IF WE TRY TO DRIVE THE VEHICLE, THE BRAKES GRAB AND JERK THE CAR VIOLENTLY. THE ONLY SOLUTIONS SEEMS TO BE TO TURN THE CAR OFF AND RESTART THE CAR. *TR

I HAVE BRAKE PROBLEMS WITH MY 2010 PRIUS. NOW THAT I SEE IT'S IN THE NEWS I REALIZE I'M NOT THE ONLY ONE. THE PRIUS HAS ISSUES WHEN I'M BRAKING AND I GO OVER ANY TYPE OF A BUMP IN THE ROAD, OR I GO OVER A POTHOLE COVER. REALLY THERE IS A BRAKING PROBLEM WHEN I AM BRAKING AND THE CAR IS DRIVING OVER DIFFERENT ROAD SURFACES, OR THERE IS BAD WEATHER. THE CAR LURCHES FORWARD- ALMOST FEELS LIKE IT'S SKIPPING A BEAT. IT MAKES MY HEART JUMP, SIMILAR TO A JOLT. I FEEL EVERY TIME THAT I WILL GET INTO AN ACCIDENT, BUT I HAVEN'T YET... THANKFULLY. THIS IS A PROBLEM WITH THE CAR AND NEEDS TO BE ADDRESSED IMMEDIATELY BEFORE SOMEONE DIES, OR GETS SERIOUSLY INJURED. THIS HAPPENS ON AVERAGE ABOUT 1-2 TIMES A WEEK. I DRIVE APPROX 150 MILES A WEEK. *TR

I PURCHASED A 2010 TOYOTA PRIUS IN OCTOBER 2009. I HAD TWO INCIDENCES WITH THE BRAKES THAT WERE SIMILAR TO WHAT HAS BEEN REPORTED IN THE PAPERS. THE FIRST WAS WITHIN THE FIRST SIX WEEKS OF OWNING THE CAR. I WAS SLOWING DOWN TO ENTER A GAS STATION AND THE CAR ACCELERATED. I HAD BEEN APPLYING THE BRAKES ALREADY, BUT THE ACCELERATION TOOK ME BY SURPRISE. I APPLIES THE BRAKES MORE FORCEFULLY AND THE CAR SLOWED. THE SECOND TIME I WAS ON MY WAY TO THE DEALER FOR A GET TO KNOW YOU WITH THE MAINTENANCE DEPT. I WAS DESCENDING A HILL WITH THE BRAKES BEING APPLIED. AGAIN THE CAR SPED UP AND I BRAKED MORE FORCEFULLY AND IT SLOWED. IT WAS SCARY. MY HUSBAND SAID THIS HAPPENED ONCE WHEN HE DROVE THE CAR, BUT HE DID NOT REMEMBER THE DETAILS. WHEN WE TOLD THE DEALER, THEY SAID THEY WERE NOT AWARE OF ANY ISSUES WITH THE 2010 PRIUS ACCELERATING OR BRAKING, BUT THAT THEY WOULD LOOK AT THE CAR. OF COURSE, THIS HAPPENED THREE TIMES OVER THREE MONTHS. THEY DIDN'T FIND ANYTHING WRONG WITH THE CAR. SOMEONE ELSE AT THE MEETING SUGGESTING ISSUES WITH THE PROGRAMMING, BUT WE WERE JUST MEETING WITH THE HEAD OF THE REPAIR DEPARTMENT. THEY ONLY KNOW WHAT TOYOTA IS TELLING THEM. NOW I SEE IN THE PAPER THAT TOYOTA CORRECTED THE ISSUE IN THEIR NEW PRIUS. SO THEY KNEW ABOUT THIS AND DIDN'T TELL US. THIS IS THE FIRST AND LAST TIME I WILL BUY A TOYOTA. *TR

MY WIFE EXPERIENCED BRAKING ANOMALIES IMMEDIATELY AFTER BEGINNING TO DRIVE HER NEW 2010 PRIUS. I ATTRIBUTED THESE TO THE WAY THE CAR DRIVES AND I HAVEN'T NOTICED ANYTHING THE FEW TIMES I HAVE DRIVEN IT. BUT THIS IS SOMETHING SHE HAS BEEN REPORTING SINCE SHE FIRST BEGAN DRIVING IT (6 MONTHS) AND SHE IS A PERCEPTIVE PERSON (M.D.). WITH DISCUSSIONS OF WHETHER TO RECALL I FIGURED I SHOULD REPORT THE PROBLEM. *TR

WHEN I APPLY THE BRAKES ON THIS VEHICLE ON A BUMPY ROAD THE BRAKES EITHER PAUSE FOR A SECOND TO APPLY OR THE ANTILOCK SYSTEMS SEEMS TO ENGAGE AND DIS-ENGAGE CAUSING A SERIOUS DISTRACTION WHILE BRAKING. THIS OCCURS DAILY AS THE AREA I LIVE IN IS MAINLY BRICK PAVED STREETS. *TR

MY CAR (2010 TOYOTA PRIUS) BRIEFLY ACCELERATES WHEN I HIT A SMALL BUMP. IT FEELS LIKE IT IS IN THE ABS SYSTEM.

I OWN A DRIVING SCHOOL IN LIVINGSTON NJ, I PURCHASED A 2010 PRIUS IN JULY 2009. I ALSO NOTICE A DELAY IN THE BRAKING SYSTEM WHILE DRIVING DOWN A HILL ONE DAY. THIS OCCURRED WHILE I APPLIED THE BRAKES. I WENT OVER A BUMP OR POTHOLE. IT SEEMED LIKE THE CAR ACTUALLY ACCELERATED MOMENTARILY AND I HAD TO KEEP APPLYING THE BRAKES TO THE FLOOR AND HOPED THAT THERE WAS ENOUGH DISTANCE TO STOP. I REMEMBER GOING DOWN A HILL, APPLYING THE BRAKES AND THE CAR WAS SLOWING DOWN, THEN I WENT OVER THE BUMP OR POTHOLE IN THE ROAD AND THE CAR TOOK OFF LIKE I WAS ACCELERATING. I FELT LIKE I HAD LOST CONTROL OF THE VEHICLE FOR AT LEAST 2 SECONDS OR 20FEET BUT FORTUNATELY NO OTHER VEHICLES WERE NEAR BY. I NOW MAKE SURE THAT I BRAKE SOONER, AND ALLOW MORE FOLLOWING DISTANCE. ESPECIALLY IN BAD WEATHER. ANTI-LOCK BRAKES SEEM TO HAVE THEIR OWN UNIQUE PROBLEMS IN THAT THE WHEELS DON'T LOCK BUT THOSE ON THE PRIUS SEEM A BIT MORE NOTICEABLE BECAUSE THEY ARE ELECTRIC AND THE PADS DON'T SLOW THE CAR LIKE NORMAL BRAKES. (AT LEAST THAT WHAT MY SALESMAN TOLD ME.) HE SAID THAT THE PADS WILL LAST OVER 200,000 MILES. HOPEFULLY I'LL BE ABLE TO DRIVE IT THAT LONG WITHOUT AN INCIDENT. BUT THE PROBLEM NOW IIS THAT PARENTS MAY NOT WANT THEIR KIDS TO LEARN WITH MY DRIVING SCHOOL, EVEN THOUGH THERE HAVE BEEN NO REAL PROBLEMS WITH TRAINING TEENAGERS YET. *TR

WHEN INITIALLY STARTING THE CAR (PRIUS 2010) TO BACK OUT OF A PARKING SPOT AND APPLYING THE BRAKES, I HAVE NOTICED A LOSS OF BRAKING (I HAVE PRESSED THE BRAKE PEDAL TO THE FLOOR WITH NO NOTICEABLE BRAKING). WHEN THE BRAKES ARE REAPPLIED, THE BRAKES "GRAB" AND CAUSE SUDDEN, JERKY STOPPING. THIS HAS OCCURRED TWICE. *TR

2010 TOYOTA PRIUS. THERE IS A PROBLEM WITH THE BRAKES WHEN I AM ON A BUMPY ROAD AND WANT TO COME TO A COMPLETE STOP. THE PROBLEM DOESN'T SEEM TO HAPPEN WHEN SLOWING OVER A BUMPY ROAD, ONLY WHEN COMING TO A COMPLETE STOP. THE CAR ALMOST SEEMS TO SKID A BIT AND I DEFINITELY DO NOT FEEL AS IF I HAVE CONTROL OF THE CAR WHEN THIS HAPPENS. WHILE IT'S ONLY A SPLIT SECOND, IT'S NOT A VERY COMFORTABLE SPLIT SECOND. THANKFULLY I HAVE NOT BEEN IN THIS SITUATION WITH ANOTHER CAR IN FRONT OF ME. *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

I AM COPYING BELOW AN INCIDENT WITH MY PRIUS' BRAKES THAT REPORTED TO TOYOTA EARLIER THIS WEEK (CONFIRMATION OF RECEIPT FROM TOYOTA AND THEN MY DESCRIPTION OF EVENT): _____________ THANK YOU FOR CONTACTING TOYOTA MOTOR SALES, U.S.A., INC. WE APPRECIATE YOUR CONSIDERATION AND HOPE TO HAVE YOUR EMAIL ADDRESSED AS QUICKLY AS POSSIBLE. OUR CURRENT OFFICE HOURS ARE MONDAY THROUGH FRIDAY FROM 5 AM TO 6 PM AND SATURDAY 7 AM TO 4 PM PACIFIC TIME. IF YOU NEED IMMEDIATE ASSISTANCE, WE RECOMMEND YOU CONTACT THE CUSTOMER RELATIONS MANAGER AT YOUR LOCAL TOYOTA DEALERSHIP. DISCUSSION THREAD CUSTOMER 02/03/2010 01:04 PM I HAVE HEARD/READ OF A FEW INSTANCES OF BRAKING ISSUES WITH PRIUS'. I WOULD LIKE TO LET YOU KNOW I EXPERIENCED THIS PROBLEM THE OTHER DAY. I WAS APPROACHING A STOP LIGHT AT A SLOW RATE OF SPEED (~20) AND BRAKING LIGHTLY WHEN I WENT OVER A SMALL BUMP ACROSS THE ROAD. THE BRAKES/PEDAL IMMEDIATELY FELT USELESS. I QUICKLY LET UP ON THE PETAL AND HIT THE BRAKES MUCH HARDER AND I WAS ABLE TO SAFETY COME TO A STOP WITHOUT ANY DANGER OR LOCKING THE BRAKES. I WANTED TO BE SURE TO LET YOU KNOW AND BE ON RECORD OF THIS ISSUE WITH MY NEW PRIUS WHICH I LOVE SO FAR SHORT OF THIS INCIDENCE. IS THERE A KNOWN ISSUE OR FIX THAT I CAN HAVE MY DEALERSHIP LOOK INTO? *TR

Mileage: 4,820

2010 PRIUS BRAKES GRAB ABRUPTLY COMING TO A COMPLETE STOP GOING THROUGH AN INTERSECTION AT ABOUT 20 MPH. I WAS ALMOST REAR-ENDED AND SUV BEHIND ME HAD TO PULL ASIDE TO KEEP FROM HITTING ME. ALSO, WHEN BACKING THE BRAKES WILL GRAB REPEATEDLY MAKING VEHICLE JERK - AND MAKES DRIVER LOOK LIKE WE CANNOT DRIVE. SEE 'PRIUS CHAT' SITE FOR MANY OTHER LIKE INCIDENTS BY OTHER DRIVERS AND SPECULATIVE SOLUTIONS. THIS ALSO HAPPENS WHEN PULLING FORWARD FROM PARKING AND HIT BRAKES IN ORDER TO MAKE A 3-POINT TURN (EXAMPLE) ETC. THIS HAPPENED THE VERY FIRST TIME I GOT INTO THE CAR WITH THE SALESMAN SITTING BESIDE ME, AND HE REMARKED WHAT GOOD BRAKES THEY WERE. I THOUGHT IT WAS JUST AN ANNOYING TRAIT OF THE CAR (BEING A HYBRID) UNTIL THE INTERSECTION INCIDENT LAST WEEK - AND THE NEW BRAKE NEWS ON THE PRIUS. THIS NEEDS TO BE ADDRESSED AS PART OF THE DEFECT BEFORE A PILE-UP COLLISION IS CAUSED. IT ALMOST SEEMS AS IF THERE IS NO 'POWER' TO THE BRAKES IN A 'GLIDING' TYPE MODE. *TR

MY 2010 TOYOTA PRIUS SLIPS WHEN THE BRAKES ARE APPLIED OVER MANHOLES, POTHOLES, AND UNEVEN SURFACES (DIFFERENCES IN PAVEMENT, ETC), AT WHICH TIME I HAVE NO CONTROL OVER THE VEHICLE. THIS OCCURS SEVERAL TIMES A WEEK, AND AT LOW SPEEDS - SINCE I'M APPLYING THE BRAKES, THE SPEEDS HAVE BEEN 30 MPH OR LESS. I TOOK THE CAR IN FOR A TEST DRIVE 2/4/10, HOWEVER, NO POTHOLES WERE AVAILABLE DURING THE TEST DRIVE, AND THE DIAGNOSTIC CHECK VIA COMPUTER INDICATED NO ERROR MESSAGES HAVE OCCURRED WITHIN THE SYSTEM. I WAS TOLD THERE WERE NO PROBLEMS, AND THAT THE BRAKES ARE WORKING CORRECTLY. *TR

1. I BOUGHT MY 2010 PRIUS NEW FROM A TOYOTA DEALER IN EARLY DECEMBER OF 2009. 2. WHEN I AM APPLYING THE BRAKES TO SLOW DOWN, IF I HIT A POTHOLE, BUMP, OR SPEED BUMP THE BRAKES WILL STOP WORKING AND THE CAR WILL LURCH FORWARD. I HAVE EXPERIENCED THIS BRAKE FAILURE AT LEAST 20 TIMES, WITH VARYING SEVERITY. IT CAN HAPPEN ANY TIME I AM TRYING TO SLOW DOWN AND HIT A BUMP OR POTHOLE (E.G.. TRYING TO SLOW DOWN BECAUSE THE CAR IN FRONT OF ME IS STOPPING, OR BECAUSE I AM APPROACHING A STOP SIGN OR RED LIGHT, OR BECAUSE I AM TURNING OR GOING INTO A CURVE). SO FAR, THIS BRAKE FAILURE HAS NOT CAUSED AN ACCIDENT BUT IT HAS CAUSED ME TO COME VERY CLOSE TO HITTING THE CAR IN FRONT OF ME ON ONE OCCASION. I HAVE COME TO NO LONGER FEEL SAFE DRIVING MY PRIUS BECAUSE I CANNOT TRUST THE BRAKES WHEN THERE ARE BUMPS OR POTHOLES IN THE ROAD. 3. I BROUGHT MY PRIUS TO THE SERVICE CENTER OF THE DEALERSHIP WHERE I PURCHASED THE CAR. I BROUGHT THE CAR IN ON 2/4/2010. THAT EVENING WHEN I SPOKE TO THE MECHANIC, HE TOLD ME THAT THE BRAKES ARE NORMAL AND THAT HE DID NOT DO ANYTHING TO FIX MY CAR AND THAT I COULD PICK MY CAR UP. I THEN SPOKE WITH THE MANAGER AND TOLD HIM THAT I DID NOT FEEL SAFE DRIVING THE CAR UNTIL THEY FIXED THE BRAKING PROBLEM. MY CAR IS STILL AT THE DEALERSHIP AND HAS NOT BEEN FIXED BECAUSE THEY ARE REFUSING TO ACKNOWLEDGE THAT THE BRAKES ARE NOT FUNCTIONING SAFELY. *TR

PRIUS 2010 OWNER. I WAS BRAKING TO ENTER A PARKING LOT FROM THE ROAD. AS I ENTERED THE LOT, THE CAR WENT OVER A BUMP IN THE PAVEMENT AND THE BRAKES FAILED FOR A VERY SHORT INSTANCE. IT DIDN'T PUT ME IN DANGER BUT IT WAS AN IMMEDIATE SCARE. (THIS HAPPENED JUST A FEW DAYS BEFORE THE MEDIA REPORTS OF THIS ISSUE CAME OUT, SO I RELATED WITH THE REPOTS WHEN THEY CAME OUT.) *TR

Mileage: 11,000

WHEN APPLYING THE BRAKES BEFORE GOING OVER A POTHOLE I NOTICED THAT MY 2010 PRIUS APPEARED TO SPEED UP FOR A SPLIT SECOND RATHER THAN SLOW DOWN. THIS HAPPENED WHEN I WENT OVER THE POTHOLE. I ALSO NOTED THE SAME SENSATION WHEN BRAKING BEHIND CARS AT A STOP LIGHT. IF I HIT A BUMP THE CAR SEEMS TO SLIGHTLY ACCELERATE RATHER THAN DECELERATE. ADDITIONALLY WHEN DRIVING SLOWLY DOWN A ICY HILL AND APPLYING THE BRAKES, THERE WAS A DELAY IN ANY BRAKING. WHEN APPLYING THE BRAKES HARDER THE CAR DID DECELERATE EVENTUALLY. THIS HAS HAPPENED A NUMBER OF TIMES, BUT IS HARD TO REPLICATE ON DEMAND. *TR

ANTILOCK BRAKES DON'T SEEM TO WORK EFFECTIVELY ON MY 2010 PRIUS, BROUGHT JUNE 2009. I'VE BEEN DRIVING FOR 48 YRS IN UPSTATE NEW YORK; AN EXPERIENCED DRIVER IN THE SNOW/ICE ROADS. THIS 2010 PRIUS IS DANGEROUS TO DRIVE ON SNOW/ICE ROADS. I THOUGHT MAYBE THE TIRES WERE LOUSY OR THAT I'M NOT ACCUSTOMED TO ANTILOCK BRAKES. BUT NOW THAT I'M HEARING ABOUT THIS VERY PROBLEM WITH OTHER 2010 PRIUS, I'M CONVINCED THAT THE PROBLEM IS WITH THE CAR'S ANTILOCK BRAKES. IF THERE'S ANY SNOW ON THE ROAD, I KNOW THAT I NEED ALOT OF ROOM TO COMPLETE A STOP AND THIS IS NOT GOING FAST AT ALL. I'VE HAD TWO NEAR CRASHES SO FAR AND AT VERY LOW SPEEDS. *TR

TWICE, WHILE I WAS BRAKING, I EXPERIENCED A SUDDEN SURGE, A LOSS OF BRAKING - AN INCREASE OF POWER. I WAS ABLE TO STOP THE CAR WITH AN AUTOMATIC SLAMMING ON THE BRAKES. NO ACCIDENT, NO INJURY OCCURRED BUT I NOW REFUSE TO DRIVE THE CAR. THE "WHAT IF" FACTOR IS TOO HIGH. I COULDN'T LIVE WITH KNOWLEDGE OF POSSIBLE HARM TO SOMEONE CAUSED BY MY DRIVING MY PRIUS!

WHEN DRIVING ON WET SURFACES, MY 2010 TOYOTA PRIUS HYBRID WILL OCCASIONALLY SKID WHEN THE BRAKES ARE APPLIED. THIS SEEMS TO HAPPEN AT SPEEDS UNDER 25MPH AND ONLY ON WET SURFACES. THE FIRST INCIDENT OCCURRED WHEN I WAS APPROACHING A STOP SIGN AT A LOW SPEED. WHEN I APPLIED THE BRAKES, THE CAR BEGAN TO SLOW DOWN WHEN IT SUDDENLY ACCELERATED WITHOUT CAUSE. THE ACCELERATION ONLY LASTED FOR A SECOND OR TWO BEFORE THE BRAKES STARTED WORKING AGAIN. I HAD MY FOOT ON THE BRAKE PEDAL THE ENTIRE TIME AND APPLIED EVEN PRESSURE. THIS ISSUE ALSO OCCURS OFTEN WHEN PULLING INTO THE UNDERGROUND PARKING GARAGE OF MY CONDOMINIUM BUILDING. WHEN THE RAMP IS WET, THIS PROBLEM WILL OFTEN OCCUR. TO AVOID THIS OCCURRENCE WHEN PULLING INTO THE GARAGE, I MUST PROCEED AT A CAUTIOUS PACE, 5-7 MPH. THIS IS VERY DISCONCERTING BECAUSE I MUST MAKE A RIGHT-HAND TURN WITH THREE FEET FROM THE BOTTOM OF THE RAMP TO AVOID HITTING THE WALL OF THE GARAGE. THE LAST OCCURRENCE WAS ON JANUARY 29TH AT 7PM. THE ROADS WERE WET. AS I APPROACHED A STOP LIGHT TO MAKE A LEFT-HAND TURN, I APPLIED THE BRAKES AS I NORMALLY WOULD IN SUCH CONDITIONS. THE AFTER THE INITIAL DECELERATION, THE BRAKES FELT LIKE THEY HAD SLIPPED AND I BEGAN TO ACCELERATE (AS DESCRIBED BEFORE). I HAD TO TURN INTO THE ADJACENT LANE TO AVOID HITTING THE CAR IN FRONT OF ME BEFORE THE BRAKES WERE FULLY APPLIED. I ALL, THIS PROBLEM HAS OCCURRED THREE TIMES WHILE DRIVING ON WET ROADS, AND 8+ TIMES WHEN DRIVING DOWN THE WET RAMP TO MY UNDERGROUND GARAGE. I HAVE CONTACTED THE TOYOTA DEALERSHIP WHERE I PURCHASED MY VEHICLE TO MAKE THEM AWARE OF THIS PROBLEM AND WAS DIRECTED TO FILE A REPORT TO NHTSA. I ALSO CALLED THE TOYOTA CUSTOMER SERVICE LINE AND WAS UNABLE TO READ A REPRESENTATIVE. *TR

WITH THE RECENT NEWS REPORTS DESCRIBING THE ISSUE WE FOUND, I CALLED TWO TOYOTA DEALERS YESTERDAY IN MY AREA ABOUT GETTING IT FIXED AND THEY WERE ABSOLUTELY NO HELP AT ALL. ONE SAID THEY DID NOT KNOW WHAT TO DO AND HAD RECEIVED NO INFORMATION FROM THE COMPANY AND THE OTHER SEEMED NOT TO BE EVEN AWARE OF THE BRAKE ISSUE, THE SERVICE SUPERVISOR KEPT SPEAKING ABOUT THE ACCELERATOR ISSUE WHICH IS DIFFERENT.

I HAVE HAD MORE THEN 10 INSTANCES COMMUTING 50 MILES A DAY WHERE I THOUGHT I WAS GOING TO REAR END SOMEONE. THE BRAKES DON'T WORK OR FEEL LIKE NORMAL BRAKES EVEN WHEN THE ROADS ARE SMOOTH.

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.

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

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

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

I KEEP MY FOOT ON THE BRAKE, EASE UP ON THE PEDAL WITH THE CAR IN REVERSE, AND THE CAR LURCHES BACKWARDS AT A SURPRISING SPEED, AND A SPEED WHICH IS UNWARRANTED BY THE AMOUNT OF PRESSURE ON THE BRAKE.

I OWN A TOYOTA PRIUS 2010 AND I LIVE IN A SNOWY CITY. I HAVE EXPERIENCED "UNUSUAL" PROBLEMS WITH BRAKES THREE TIMES IN MONTH OF JANUARY. FIRST TIME I WAS TAKING MY TWO CHILDREN TO SCHOOL AND AS I WAS APPROACHING STOP SIGN, I SLOWED DOWN AS USUAL AND APPLIED BRAKE. WHEN I WAS ALMOST AT THE STOP SIGN, I REALIZED THAT CAR WASN'T STOPPING, SO I PANICKED AND PRESSED BRAKE PEDAL HARD AND THEN I NOTICED THE ABS STARTED TO WORK AND I PASSED THE STOP SIGN ABOUT THREE METERS, ROAD WAS COVERED WITH SNOW. SECOND TIME I WAS GOING TO WORK ON A WET ROAD AND NOT ICY. I WAS APPROACHING A TRAFFIC LIGHT AND AS I SLOWED DOWN I ALSO CHANGED LANE AND APPLIED BRAKE. BEFORE THE TRAFFIC LIGHT I NOTICED THAT AS IF I WAS NOT BRAKING, SO I PRESSED HARD ON THE BRAKES AND IT STOPPED. THIRD TIME I DROPPED MY CHILDREN TO SCHOOL AND STARTED TO GO TO WORK AND I EXPERIENCED SIMILAR PROBLEM WITH BRAKES, WET ROAD AND NOT ICY, BUT THIS TIME I PANICKED BECAUSE OF SOME CARS ON THE ROAD, I PRESSED HARD ON THE BRAKE AND IT STOPPED IN FRONT OF THE STOP SIGN AND I HAD TO BACK UP. SO I CALLED MY HUSBAND AT HIS WORK AS I WAS VERY NERVOUS ABOUT THIS SITUATION. HE SAID IT IS PROBABLY BECAUSE OF THE WEATHER AND MAY BE BECAUSE I AM VERY CAREFUL ABOUT THE NEW CAR. SO HE SAID THAT HE WOULD TEST DRIVE THE CAR TO SEE IF THERE IS ANY PROBLEM. HE DROVE THE CAR TO WORK FOR TWO WEEKS, 700 MILES, AND HE TOLD ME THAT HE HAD ONLY ONCE "UNUSUAL" PROBLEM WITH BRAKES SIMILAR TO WHAT I HAD. TWO DAYS AGO I HEARD ABOUT PRIUS BRAKE PROBLEMS AND I TOOK MY CAR TO THE DEALER. DEALER SAID THAT INSPECTION HAS FOUND NO PROBLEM. AND HERE I AM DRIVING THIS CAR AGAIN. *TR

JUST REINFORCING WHAT HAS ALREADY BEEN REPORTED ABOUT THE 2010 MODEL PRIUS. I HAVE A 2010 PRIUS THAT WAS PURCHASED IN NOVEMBER 2009, AND I HAVE ON NUMEROUS OCCASIONS HAD ISSUES WHEN BRAKING AT SLOWER SPEEDS AND DRIVING OVER POTHOLES OR DIPS. THE BRAKES SEEM TO GIVE OUT FOR A MOMENT AND THE CAR ACCELERATES, RESULTING IN THE NEED TO SLAM DOWN THE BRAKE HARDER IMMEDIATELY. THE INCIDENT USUALLY ONLY LASTS FOR A SECOND OR TWO, AND I AM TRYING TO DRIVE EXTRA CAREFULLY TO COMPENSATE. BUT THE DELAY IN BRAKING COULD ABSOLUTELY RESULT IN A TRAFFIC ACCIDENT DUE TO THE INCREASED TIME TO DECELERATE. *TR

I WOULD LIKE TO ADD MY REPORT TO YOUR OTHER COMPLAINTS ABOUT 2010 TOYOTA PRIUS BRAKES. I PURCHASED MINE IN JULY AND SINCE THEN HAVE EXPERIENCED 4 (FOUR) INSTANCES OF THIS PROBLEM. IN EACH CASE, I WAS DECELERATING WITH THE BRAKES STEADILY APPLIED, AND ROLLED OVER A BUMP OR POTHOLE IN THE ROAD. AT THAT MOMENT, THE BRAKES STOPPED WORKING, OR THE BRAKING POWER WAS SEVERELY REDUCED, AND THE CAR FELT AS IF IT LURCHED FORWARD. APPLYING MORE PRESSURE ON THE BRAKES WHEN THIS OCCURS DOES CAUSE THE BRAKING TO RESUME, BUT THERE IS A DELAY OF PERHAPS 1/2 SECOND. I HAVE NOT HAD AN ACCIDENT SO FAR, BUT IF I WERE BEHIND ANOTHER CAR WHICH WAS ALSO BRAKING WHEN THIS HAPPENED, THERE IS A HIGH LIKELIHOOD THAT MY CAR WOULD SMASH INTO THE OTHER CAR'S REAR. *TR

I HAVE A 2010 TOYOTA PRIUS, AND I AM SHOCKED THAT THIS CAR WAS NOT INCLUDED IN THE GIGANTIC TOYOTA RECALL. WHY? BECAUSE THE 2010 TOYOTA PRIUS EXHIBITS BRAKE FAILURE AND SUDDEN ACCELERATION WHILE SLOWING DOWN ON BUMPY ROADS. FOR EXAMPLE, IF YOU'RE SLOWING DOWN TOWARDS A RED LIGHT, AND THEN ALL OF A SUDDEN YOU HIT A POTHOLE, THE CAR WILL SUDDENLY ACCELERATE AND MAY CAUSE A CRASH WITH THE PERSON AHEAD OF YOU! THIS HAPPENS ALL THE TIME AND IS EXTREMELY DANGEROUS. THOUSANDS OF 2010 PRIUS DRIVERS WORLDWIDE ARE ALSO HAVING THIS BRAKE FAILURE/SUDDEN ACCELERATION ISSUE WITH THEIR 2010 PRIUS AS WELL! TAKE A LOOK AT JUST A FEW OF THESE DISCUSSIONS WHICH ARE TAKING PLACE, WHERE PEOPLE ARE HAVING UNCONTROLLABLE SUDDEN ACCELERATION WITH THEIR 2010 PRIUS: HTTP://TINYURL.COM/YJ359RH WILL NHTSA PLEASE DO SOMETHING ABOUT THIS? *TR

MY WIFE ALSO EXPERIENCED THE SAME PROBLEM TWO WEEKS AGO WHEN IT RAINED IN LOS ANGELES. I REPORTED IT TO THE DEALER LAST OCTOBER BUT THEY SAID THERE IS NO PROBLEM IN MY CAR. SO I INSISTED THE INSPECTION SO THE DEALER ARRANGED TO SHOW MY PRIUS TO THE EXPERT FROM TOYOTA CENTER AND I HAD TO WAIT IT 2 MONTHS. LAST MONTH (EARLY JANUARY) IT WAS INSPECTED BY THE EXPERT FROM TOYOTA CENTER AT THE DEALERSHIP BUT I HEARD THE SIMPLE ANSWER FROM THE DEALER THAT THE TECHNICIAN FOUND NO PROBLEM.

ADDITIONALLY, THE AVID FACTORY TIRES ON THE CAR ARE NOT EFFECTIVE ON WET PAVEMENT; THEY SKID.

2010 TOYOTA PRIUS MODEL III.

WHEN CAREFULLY BRAKING MY 2010 TOYOTA PRIUS AT LOW SPEEDS (40 MPH AND LOWER), A SMALL DIP OR BUMP IN THE ROAD WILL CAUSE THE CAR TO RELEASE THE BRAKES AND THE EFFECT IS A SUDDEN ACCELERATION OR RELEASE OF THE BRAKING SYSTEM WHICH LASTS APPROXIMATELY 1 SECOND. THIS FAILURE IN THE VEHICLE IS SEEMINGLY UNRELATED TO A MECHANICAL ISSUE AND FEELS MORE LIKE AN ELECTRICAL ISSUE, SINCE THERE IS NO STIFF PEDAL OR OBSTRUCTION NEAR THE PEDAL. THE FAILURE OCCURS ON A SEMI-REGULAR BASIS. I TOOK THE CAR INTO THE TOYOTA DEALERSHIP WHERE I BOUGHT MY VEHICLE, SUBURBAN TOYOTA LOCATED IN TROY, MICHIGAN, AND REPORTED THE PROBLEM, APPROXIMATELY 4 MONTHS FROM THE TIME I BOUGHT THE CAR (JUNE 2009). THE MECHANICS KEPT THE VEHICLE OVER NIGHT. THE DEALER THEN REPORTED THAT THEY DID EXPERIENCE THE PROBLEM WHEN TESTING THE VEHICLE AND SAID IT WAS RELATED TO THE ANTI-LOCK BRAKING SYSTEM AND THAT THE CAR WAS DESIGNED TO MOVE AROUND AN OBJECT RATHER THAN HEAVY BRAKING. THEY DID NOTHING TO FIX THE CAR. THE PROBLEM PERSISTS AND I HAVE HEARD SIMILAR COMPLAINTS OF UNINTENDED ACCELERATION, BOTH WHEN BRAKING AND COASTING. I AM CONCERNED I WILL AT SOME POINT HIT A CAR THAT IS TOO CLOSE IN FRONT OF ME. *TR

THIS COMPLAINT IS REGARDING MY 2010 TOYOTA PRIUS WHICH I PURCHASED IN AUGUST OF 2009. BEFORE MY FIRST OIL CHANGE WAS DUE I HAD NOTICED THE VEHICLE'S TENDENCY TO NOT RESPOND INSTANTLY TO MY STEPPING ON THE BRAKE, AND THEN LURCH FORWARD WHEN THE BRAKES DID ENGAGE. MY BRAKES ALSO SQUEAL EVEN WHEN THE WEATHER IS DRY. I REPORTED THIS TO THE DEALER WHEN I TOOK IT IN FOR TIRE ROTATION AND OIL CHANGE. OF COURSE THEY TOLD ME THE MOMENTARY PAUSE OF THE BRAKES "WAS NORMAL" AND THEY DID NOT HEAR THE BRAKES SQUEAL. WELL MY VEHICLE IS STILL DOING BOTH OF THESE THINGS AND IT SEEMS I AM NOT THE ONLY ONE WITH A CONCERN REGARDING THE BRAKES. PLEASE ADD MY VEHICLE TO THE LIST OF OWNERS WHO ARE WORRIED ABOUT THESE BRAKES. I HAVE BEEN DRIVING FOR 40 YEARS, EVERY MAKE AND MODEL, INCLUDING TRACTORS ON THE FARM AND I KNOW THERE IS A PROBLEM NO MATTER WHAT THAT DEALERSHIP OR TOYOTA SAYS. *TR

WHEN DRIVING MY PRIUS, I HAVE NOTICED THE FEELING OF BEING THROWN FORWARD FOR A SPLIT SECOND AFTER I HAVE APPLIED THE BRAKES WHEN ON AN UNEVEN SURFACE, IE A GRATE IN THE ROAD.

WE PURCHASED A 2010 TOYOTA PRIUS IN JULY 2009 AND HAVE BEEN HAVING PROBLEMS WITH THE BRAKES THAT CORRESPOND PRECISELY TO WHAT IS NOW BEING WIDELY REPORTED IN THE NEWS. SPECIFICALLY, WHEN GOING OVER BUMPS IN THE ROAD WHILE BRAKING, SEVERAL TIMES I HAVE EXPERIENCED THE CAR SUDDENLY AND MOMENTARILY SPEEDING UP AND LURCHING FORWARD RATHER THAN SLOWING DOWN. MY WIFE HAS ALSO REPORT BRAKING PROBLEMS. INDEED, JUST LAST WEEK I QUERIED HER TO MAKE SURE IT WAS THE BRAKES RATHER THAN THE ACCELERATOR, AND SHE CONFIRMED THE PROBLEM OCCURRED WHILE BRAKING. SO FAR THESE INCIDENTS HAVE NOT RESULTED IN DAMAGE OR CRASH, BUT WE ARE OBVIOUSLY NOW VERY CONCERNED ABOUT USE OF THE CAR, ESPECIALLY DURING SLIPPERY WINTER CONDITIONS HERE IN WASHINGTON, DC.

I UNDERSTAND TOYOTA KNEW ABOUT THE ANTI-LOCK BRAKE ISSUE ON PRIUS BUILD BEFORE JANUARY 2010. I OWN A 2010 PRIUS, PURCHASED IN OCTOBER 2009. I HAVE HAD ONE INSTANCE OF MOMENTARY BRAKE LOSS WHILE DRIVING OVER A BUMP. IT WAS A BIT FRIGHTENING AT THE TIME, BUT THE PROBLEM HAS NOT RE-OCCURRED. SO I HAVE NOT REPORTED THE INCIDENT UNTIL TODAY. I ASSUME MANY OTHER PRIUS OWNERS MAY HAVE EXPERIENCED THE SAME PROBLEM, BUT DID NOT COMPLAIN, SINCE THE OCCURRENCE IS SO INFREQUENT. IF TOYOTA CARES ABOUT SAFETY, THEY WILL DO THE RIGHT THING AND SAY "SAFETY IS TOYOTA'S NUMBER ONE PRIORITY. OUR ENGINEERS ARE WORKING ON A FIX FOR THE PRIUS'S WITH THE ANTI-LOCK BRAKE ISSUE AND REST ASSURED, TOYOTA WILL FIX THOSE VEHICLES." I AM VERY DISAPPOINTED THAT TOYOTA KNEW ABOUT THIS PROBLEM AND HAS NOT TAKEN CARE OF IT. HASN'T TOYOTA LEARNED ENOUGH FROM THE STICKY GAS PEDAL PROBLEM. TOYOTA NEEDS TO BE PROACTIVE IN MAINTAINING ITS IMAGE AS A RELIABLE CAR COMPANY THAT CARES ABOUT SAFETY. *TR

THE SECOND TIME IT HAPPENED WHEN I WAS DOING A U-TURN IN AN UNLEVELED PART OF THE ROAD AND SINCE IT HAD HAPPENED BEFORE I JUST APPLIED THE BRAKE UNTIL THE SKID WARNING LIGHT TURNED OFF.

I HAVE HAD TWO INSTANCES WHEN I LOST AT LEAST HALF OF MY BRAKING POWER WHEN GOING OVER A SLIGHT BUMP IN THE ROAD. THE FIRST INSTANCE WAS ABOUT TWO MONTHS AGO AND THE SECOND WAS ON FEB. 2ND. IN BOTH CASES I WAS COMING UP TO A FREEWAY ON RAMP STOP LIGHT AND WENT OVER A BUMP IN THE ROAD. I WENT BEYOND THE LIGHT BOTH TIMES AND FORTUNATELY THERE WERE NO OTHER CARS IN MY WAY. I ALSO HAVE A PROBLEM WITH THE BRAKES GRABBING SO SEVERELY THAT MY SEAT BELT ENGAGES WHEN I HAVE JUST FEATHER TOUCHED THE BRAKES. THIS HAS OCCURRED AFTER STARTING THE CAR AND RELEASING THE BRAKE TO MOVE FORWARD OR BACKWARD, BUT NOT YET STEPPED ON THE GAS. I HAVE HAD THE CAR INTO THE DEALERSHIP FIVE TIMES SINCE PURCHASING IT IN SEPTEMBER FOR THESE ISSUES AND HAVE REPEATEDLY BEEN TOLD THIS WAS NORMAL. I EVEN REQUESTED THAT A REGIONAL MECHANIC CHECK IT OUT AND HE DID SO. HE TOLD ME HE WAS ABLE TO HAVE THE CAR RESPOND AS I DESCRIBED AND IT WAS IN NORMAL RANGE. I DISAGREE. THERE HAS BEEN THREE OTHER PEOPLE WHO HAVE BEEN WITH ME WHEN THIS HAS OCCURRED AND NOT ONE OF THEM HAS CONSIDERED THIS ANYWHERE "NORMAL".

THE FIRST TIME IT HAPPENED I LOOKED BACK TO SEE IF THERE HAD BEEN ANY ICE IN THAT SECTION OF THE ROAD AND THERE WAS NONE. THE OTHER TIME IT HAPPENED AS I WAS NEARLY STOPPED AND THE SENSATION WAS MORE LIKE I HAD BEEN BUMPED FROM BEHIND BY ANOTHER CAR.

I APPLIED THE BRAKES AND THE CAR FAILED TO STOP. I PUMPED THE BRAKES SEVERAL TIMES BEFORE THEY "GRABBED." LUCKILY THERE WAS NO CAR IN FRONT OF ME OR BEHIND ME. IF THERE HAD BEEN A CAR IN FRONT, I WOULD SURELY HAVE REAR ENDED IT. I THOUGHT BEING A "NEW" PRIUS DRIVER I HAD DONE SOMETHING WRONG BUT IT DEFINITELY CAUSED ME SOME PANIC.

2010 PRIUS BRAKES APPEAR TO BECOME INOPERABLE DURING TRANSITION FROM ELECTROMAGNETIC TO HYDRAULIC BRAKING. I'VE HAD THIS OCCUR AN THREE OCCASIONS, TWICE DURING AGGRESSIVE BRAKING (NEAR MISSES). ONCE THIS OCCURRED AT LOW SPEED ON A PATCH OF SO-SO ROAD DURING LIGHT RAIN. THE OTHER TWO TIMES THIS HAPPENED AT 40+MPH ON VERY GOOD DRY ROAD. I TOOK MY CAR IN TO MY LOCAL TOYOTA DEALERSHIP YESTERDAY TO EVALUATE THIS CONCERN AND WAS INFORMED THAT MY BRAKES ARE NOT MALFUNCTIONING. THE DEALER SEEMED UNAWARE OF THE ISSUE AND THE FACT THAT TOYOTA HAD CORRECTED THIS ISSUE IN THE CARS CURRENTLY COMING OFF OF THE ASSEMBLY LINE. THE DEALER POSITION SEEMS TO BE THAT THE PRIUS BRAKE SYSTEM IS ADVANCED AND DOES NOT OPERATE LIKE OTHER BRAKE SYSTEMS. MY POSITION IS THAT BRAKE SYSTEM DESIGN SHOULD NOT CONTRIBUTE TO DRIVER PANIC DURING AGGRESSIVE BRAKING. *TR

OUR 2010 TOYOTA PRIUS SURGES (ACCELERATES) FOR A FRACTION OF A SECOND WHENEVER THE BRAKES ARE APPLIED AS IT HITS A SMALL BUMP OR SLICK SPOT IN THE ROAD. THIS HASN'T CAUSED ANY ACCIDENTS, BUT WE DRIVE THE CAR PRIMARILY AT LOW SPEEDS (40 MPH OR LESS) AND HAVEN'T BEEN INVOLVED IN ANY SITUATIONS (YET) THAT REQUIRED EVASIVE ACTION. WE ARE CONCERNED THAT, AT HIGHER SPEEDS, OR IN A CASE WHERE SOMEONE PULLS OUT IN FRONT OF US AND WE HAVE TO APPLY THE BRAKES QUICKLY, THE VEHICLE WILL NOT RESPOND APPROPRIATELY. I HAVE TOLD MY TOYOTA DEALER ABOUT THIS PROBLEM TWICE, AND THEY HAVE NO RESPONSE. ABOUT WHAT TO DO ABOUT THE PROBLEM. ALL THEY SAID WAS THAT THE CAR HAS NOT BEEN RECALLED, AND THAT I SHOULD TOUCH BASE WITH THEM PERIODICALLY FOR UPDATES.

I PURCHASED A 2010 PRIUS IV IN JUNE 2009. I LIVE IN THE KANSAS CITY AREA. BEGINNING IN NOVEMBER WHEN THE WEATHER TURNED COLD, USUALLY BELOW FREEZING, I NOTICED THAT WHEN I APPLY MY BRAKES SOMETIMES THEY WILL SLIP JUST FOR A FRACTION OF A SECOND. THIS USUALLY OCCURS BEFORE THE CAR HAS A CHANCE TO WARM UP BUT HAS OCCURRED WHEN THE CAR IS WARMED UP. THE BRAKES WILL SLIP WHEN I GO OVER A PORTION OF THE ROAD WHERE THE PAVEMENT IS BUCKLED, OR THERE IS A DEPRESSION SUCH AS DRIVING OVER A MANHOLE COVER, POTHOLE OR CONSTRUCTION CUT THAT WAS NOT PROPERLY FILLED. THE EXPERIENCE IS LIKE BRAKING OVER A SMALL PATCH OF ICE. I NOTIFIED THE DEALER OF THIS PROBLEM IN DECEMBER BUT DIDN'T MAKE AN APPOINTMENT TO HAVE THE CAR INSPECTED. AFTER READING AN AP NEWS RELEASE ON THIS TOPIC, WHICH DESCRIBED THE EXACT SYMPTOMS I AM EXPERIENCING, I MADE AN APPOINTMENT FOR 12 FEB TO HAVE THE BRAKES INSPECTED.

WHEN APPLYING BRAKES, TO MY PRIUS 2010, ON AT LEAST 3 OCCASION THE BRAKES SEEM TO FAIL. APPLYING MORE PRESSURE DOESN'T SEEM TO WORK RIGHT AWAY, THEN THE BRAKES GRAB HARD. ONLY NOTICED AT SLOWER SPEEDS, AND ROUGHER ROADS. *TR

2010 PRIUS PURCHASED JULY 2009. TURNING INTO MY DRIVEWAY WHILE BRAKING (WHICH HAD A POTHOLE IN FRONT OF IT) MY CAR FELT LIKE IT WAS LURCHING FORWARD OUT OF CONTROL AFTER IT HIT THE POTHOLE. I WOULD HAVE THOUGHT THAT THE POTHOLE WOULD IMPEDE MY FORWARD PROGRESS NOT INCREASE IT! I WAS GOING VERY SLOWLY SO THE INCIDENT WAS MOMENTARY, BUT IT DID SCARE ME. THIS HAPPENED SEVERAL TIMES BEFORE I LEARNED HOW TO AVOID THE POTHOLE. I THOUGHT IT WAS VERY STRANGE BUT ONCE I STARTED TO AVOID THE POTHOLE I FORGOT ABOUT IT. SO I DID NOT PURSUE IT UNTIL I READ THE DESCRIPTIONS OF THE ROUGH ROAD COMPLAINTS AND REALIZED THAT WAS EXACTLY WHAT HAD HAPPENED TO ME AND THAT I SHOULD REPORT IT HERE. THE DATES, TIME AND MILEAGE ARE ACTUALLY UNKNOWN BECAUSE I DID NOT MAKE A NOTE OF IT AT THE TIME. *TR

Mileage: 3,500

I BOUGHT AT 2010 PRIUS ON NEW YEAR'S EVE, AND SINCE THEN, ON SEVERAL OCCASIONS (PROBABLY ABOUT 7-8 TIMES) WHEN HITTING A POTHOLE, THE CAR FEELS LIKE IT LUNGES FORWARD, OR ALMOST ACCELERATES. MAYBE IT'S JUST THAT THE BRAKE GOES OUT COMPLETELY, BUT IT'S ALWAYS WHEN BRAKING FOR A POTHOLE OR DIP THAT MY CAR GOES LUNGING FORWARD. LUCKILY NO ACCIDENTS OR ANYTHING HAVE RESULTED AS OF YET, BUT IT CONCERNS ME. I'VE BEEN TOO BUSY TO MENTION IT TO THE DEALER YET, ALTHOUGH I DID MENTION IT BRIEFLY TO MY SALESPERSON WHEN HE DID A FOLLOW-UP CALL TO SEE HOW I WAS DOING WITH THE NEW CAR. I'VE MADE AN APPT. AT MY LOCAL DEALER FOR MONDAY TO HAVE IT LOOKED AT, BUT GIVEN THE NEWS THIS MORNING, I FELT I SHOULD REPORT IT BECAUSE I'VE DEFINITELY BEEN EXPERIENCING WHAT'S BEING REPORTED. *TR

1. WE PURCHASED A 2010 PRIUS SIX MONTHS AGO. WE HAVE HAD FOUR INCIDENTS BRAKING WHERE WE FEEL THE ABS OVER-COMPENSATES WHEN THE WHEELS ARE ON DIFFERENT SURFACES (E.G. GRAVEL/PAVEMENT, PUDDLE/PAVEMENT, ETC.). TWO OF THE FOUR INCIDENTS ARE NOTABLE BECAUSE IT FELT AS THOUGH I HAD LOST CONTROL OF BRAKING AND I WAS GOING TO 1. REAR-END ANOTHER CAR AND 2. GO OFF AN EMBANKMENT. I AM NOT AN AGGRESSIVE DRIVER. TODAY, I WAS ALARMED TO LEARN,--REPORTED IN THE NEWS--THAT OTHER DRIVERS ARE EXPERIENCING THE SAME ISSUE. TOYOTA HAS CHECKED OUT MY CAR (AT THE 5,000 MILE OIL CHANGE), BUT REPORTS NOTHING WRONG. SOMETHING IS WRONG! IF FEELS AS THOUGH THE ABS OVER-COMPENSATES ON ALL FOUR WHEELS WHEN THE SURFACE UNDER ONE WHEEL IS "IRREGULAR" AND CAUSES THE ABS TO REACT TO SLIPPING/SLIDING. I'VE OWNED SIX CARS WITH ABS, BUT NONE OF THEM GAVE ME THE FEELING THAT I'D LOST CONTROL BRAKING. THERE IS SOMETHING WRONG WITH THIS CAR'S ABS AND I AM CONCERNED THAT TOYOTA WILL NOT ADDRESS IT IN A PROMPT MANNER. YOUR AUTO-FILL FORM REQUIRES THAT I SPECIFY A DATE OF INCIDENT. FOUR TIMES, BETWEEN NOVEMBER 2009 AND JANUARY 2010, WE FEEL WE'VE LOST CONTROL OF OUR ABILITY TO BRAKE THIS CAR AT VERY REASONABLE (BRAKING) SPEEDS AND DISTANCES. IT'S NOT JUST ONE INCIDENT. *TR

MY 2010 TOYOTA PRIUS HAS ISSUES WITH THE BRAKING SYSTEM AT DIFFERENT TIMES, PARTICULARLY WHEN TRAVELING OVER BUMPS, ETC. THERE IS A MOMENTARY LOSS OF BRAKING CONTROL. THERE HAVE BEEN NO ACCIDENTS BUT CERTAINLY SCARY TO DRIVE. NOTHING HAS BEEN DONE ABOUT THE FAILURE. I CONTACTED MY DEALERSHIP AS THE CAR IS STILL UNDER WARRANTY AND THEY SAID ALL THEY COULD DO WAS TAKE MY NAME AND NUMBER DOWN. *TR

Mileage: 1,000

EVERY TIME WE DRIVE DOWN A HILL NEAR OUR HOUSE AND HIT A POTHOLE/CRACK IN THE ROAD, THE 2010 PRIUS SEEMS TO ACCELERATE THROUGH THE POTHOLE EVEN THOUGH I AM BREAKING DOWN THE HILL. THIS HAS HAPPENED SINCE THE FIRST DAY WE DROVE THE CAR (IN AUGUST 2009). THERE HAVE BEEN NO ACCIDENTS OR INJURIES SINCE THIS ROAD IS NOT HEAVILY TRAVELED, BUT IT MAKES ME HESITANT TO DRIVE MY CAR IF I HAVE TO GO DOWN THAT HILL. *TR

WHEN DRIVING THROUGH AN ALLEY, AT THE END, BEFORE I STOP FOR THE STREET, THERE IS A POTHOLE. TWICE I HIT IT WHILE BRAKING FOR THE STOP SIGN AT THE STREET AND SOMETHING FELT WEIRD, LIKE THE BRAKE DIDN'T QUITE HOLD. HONESTLY I THOUGHT I MOVED MY FOOT FROM THE BRAKE OR SOMETHING. I THINK IT MAY HAVE HAPPENED ONE OTHER TIME. I AM CONSCIOUS OF IF BECAUSE I WANTED TO BE AWARE IF I WAS DOING SOMETHING WRONG SO I COULD CORRECT IT. *TR

Mileage: 2,000

JUST ADDING FUEL TO THE FIRE, BUT I HAVE A 2010 TOYOTA PRIUS AND THERE IS DEFINITELY A BRAKING ISSUE. SPECIFICALLY, I NOTICE IT WHEN I HIT A POTHOLE (AND I LIVE IN LOS ANGELES, WHICH IS ALL THE TIME). I FRANKLY DON'T KNOW WHETHER THERE'S ACTUAL ACCELERATION OR JUST TOTAL LOSS OF BRAKING (I BASICALLY NOTICE IT AT SLOWER CITY SPEEDS--BRAKING WHILE TURNING A CORNER, FOR EXAMPLE), BUT THERE IS DEFINITELY A MOMENTARY "SURGE." IT HAPPENS REGULARLY (IGNORE THE DATE I HAD TO ENTER BELOW)--SO MUCH SO THAT AT THIS POINT I ANTICIPATE IT. *TR

I STEPPED ON MY BRAKE AND MY CAR KEPT ACCELERATING. *TR

Mileage: 400

MY 2010 PRIUS SEEMS TO MOMENTARILY LURCH FORWARD WHEN DRIVING OVER BUMPS AND BRAKING AT THE SAME TIME. IT SEEMS THAT THE BRAKE DISENGAGES MOMENTARILY AND THEN RE-ENGAGES. I HAVE NOT HAD ANY ACCIDENT, AND THE TIME OF DISENGAGEMENT IS VERY SHORT, BUT IT DOES SCARE ME A LITTLE. *TR

Mileage: 5,500

MY 2010 PRIUS BRAKES SKIP WHEN GOING OVER LARGE BUMPS OR HOLES MAKING THE CAR SURGE FORWARD RATHER THAN SLOW. I NOTICE IT AT A HIGHER RATHER THAN LOWER SPEEDS. I THOUGHT IT WAS JUST ME UNTIL I HEARD OTHERS HAVING THE SAME PROBLEM. IT WAS A DAILY PROBLEM AS I GO TO WORK THE SAME DAY AND IT HAPPENED IN THE SAME SPOT SO THE APPROX. INCIDENT DATE BELOW IS SORTA INVALID. IN ADDITION, I DON'T KNOW I CHECKED THE CORRECT "BRAKE" SECTION, I JUST KNOW IT'S THE BRAKES. *TR

Mileage: 3,000

WITH MY 2010 PRIUS (PURCHASED LATE AUG 2009), IT HAS EXACTLY THE SAME PROBLEM OTHERS HAVE DESCRIBED. WHILE GOING DOWNHILL, WITH THE BRAKES APPLIED, HITTING POTHOLES OR BUMPY ROAD SURFACE CAUSES THE CAR TO ACCELERATE. IT HAPPENS "EVERY SO OFTEN". IT'S QUITE OBVIOUS WHEN IT HAPPENS AND CLEARLY A SAFETY HAZARD. I HAVE TAKEN IT INTO THE DEALER BUT THE PROBLEM IS NOT REPRODUCIBLE EVERY TIME AND THEY HAVE NO OFFICIAL WORD FROM TOYOTA ON IT. *TR

MY 2010 TOYOTA PRIUS HAS A PROBLEM WITH BRAKING SPECIFICALLY WHEN THE CAR MOVES ON A BUMPY OR SLIPPERY SURFACE, I CAN FEEL A PAUSE IN THE BRAKING AND IT FEELS AS THOUGH I GLIDE A FEW FEET FURTHER THAN I SHOULD WHEN I BRAKE THE PEDAL IS FULLY PRESSED DOWN.

IN EARLY JANUARY, WHEN BACKING OUR 2010 TOYOTA PRIUS OUT OF THE GARAGE, THE BRAKE PEDAL BECAME OVERLY-SENSITIVE AND BEGAN LOCKING THE BRAKES WHEN ANY PRESSURE AT ALL WAS APPLIED TO THE PEDAL. THIS WENT ON FOR ABOUT A DOZEN ITERATIONS UNTIL THE TRANSMISSION WAS SHIFTED TO DRIVE. AT THAT POINT THE BRAKES BEGAN BEHAVING NORMALLY.

ON 1-10-10, I TOOK IT IN FOR THE 5000 MILE MAINTENANCE CHECK, BUT DID NOT TELL THE DEALER MY PROBLEMS ,BECAUSE I THOUGHT THE CAR WAS STILL IN A "BREAKING IN" PERIOD AND WOULD RESOLVE ITSELF.

SINCE THEN, I ATTEMPT TO NOT BRAKE DIRECTLY OVER A POTHOLE. *TR

I HAVE HAD NUMEROUS PROBLEMS WITH THE BRAKES ON MY NEW 2010 PRIUS WHICH I PURCHASED A FEW DAYS BEFORE XMAS. I HAVE REPORTED TWO OF THE EPISODES WITH TOYOTA - THE FIRST TIME THE PHONE REP SEEMED TO LISTEN CAREFULLY TO MY ACCOUNT OF WHAT HAPPENED - THE LAST TIME I CALLED THE PHONE REP SEEMED TO BLOW ME OFF AND DIDN'T' ASK ANY FOLLOW UP QUESTIONS BUT SAID TO TAKE IT TO MY LOCAL DEALER FOR REPAIRS. THIS WAS BEFORE THE BRAKE ISSUE BECAME KNOWN AS A WIDESPREAD PROBLEM - THE LOCAL DEALER WHERE I PURCHASED THE CAR TOLD ME THERE WERE NO PROBLEMS - AGAIN THIS IS BEFORE THE ANNOUNCEMENT OF THE POTENTIAL RECALL - BOTH TIMES - I WAS DRIVING SLOWLY AND WHEN I PUT MY FOOT ON THE B RAKE IT NOT ONLY DIDN'T STOP BUT ACTUALLY SEEMED TO JUMP FORWARD SEVERAL FEET. FORTUNATELY THERE WERE NO CARS IN FRONT OF ME SO I DID NOT HIT ANYTHING. I HAVE ALSO HAD REPEATED BRAKING PROBLEMS WHEN I AM BACKING UP- AND WHEN I FIRST DRIVE THE CAR AFTER NOT DRIVING IT FOR AN HOUR OR SO - JUST A BARE TOUCH OF THE BRAKE AND IT STOPS SO HARD - THE FIRST TIME I THOUGHT I HAD HIT SOMETHING - THE BRAKES WILL CONTINUE TO JERK AND JOLT ME UNTIL I START TO DRIVE FORWARD - THEN IT SEEMS TO CORRECT ITSELF. I HAVE HAD THE CAR ONE MONTH - I LIVE IN THE LOS ANGELES AREA. *TR

Mileage: 1,500

SEVERAL TIMES I HAVE APPLIED THE BRAKES ON MY 2010 PRIUS ONLY TO FEEL THE CAR CONTINUE TO MOVE FORWARD WITHOUT ANY FEELING OF BRAKE ENGAGEMENT... THIS WOULD LAST ONLY A SHORT TIME... PERHAPS A SECOND... THIS OCCURRED WHEN TRYING TO STOP ON BUMPY ROADWAY. *TR

I WANT TO COMPLAIN ABOUT THE BRAKING PROBLEM WITH MY TOYOTA PRIUS 2010 WHICH I PURCHASED IN NOVEMBER OF 2009.

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

Mileage: 300

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

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

Mileage: 10,514

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

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 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

Mileage: 1,000

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

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

Mileage: 1

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

WITH OUR 2010 TOYOTA PRIUS, MY WIFE HAD AN ACCIDENT WHERE THE VEHICLE SLID INTO A SNOW BANK WITHIN 1 BLOCK OF OUR HOME. JUST PRIOR TO THIS, I NOTICED THAT THE VEHICLE'S ANTI-LOCK BRAKE DID NOT SEEM TO FUNCTION PROPERLY. I USED TO WORK FOR GENERAL MOTORS IN MICHIGAN AND KNOW THE SOUND THAT COMES FROM WORKING ANTI-LOCK BRAKES. THE ANTI-LOCK BRAKES USED TO WORK EARLIER IN 2009...I HAD TO STOP ON A WET PAINT STRIPE AND THE ANTI-LOCKS MADE THE DISTINCTIVE RATCHETING SOUND. IN DECEMBER 2009, THAT SOUND AND THE LOSS OF BRAKING TRACTION WAS EVIDENT. NOT UNTIL I SEE THAT THERE IS NEWS IN THE MEDIA RECENTLY ABOUT THE PRIUS DID I THINK TO LODGE A COMPLAINT. THIS ACCIDENT CAUSED ME (AND MY INSURER) $1,024 IN DAMAGE TO OUR FRONT BUMPER. *TR

Mileage: 15,000

RE: 2010 PRIUS BRAKING ISSUES BEGINNING WITHIN THE FIRST 500 MILES OF OWNING VEHICLE. WHEN FIRST START UP VEHICLE BRAKES ARE OVERLY SENSITIVE, MAKING IT IMPOSSIBLE TO STOP THE CAR SMOOTHLY. I HAVE BEEN ABLE TO CORRECT THE PROBLEM BY SHUTTING OFF THE ENGINE AND RESTARTING THE CAR. THIS PROBLEM OCCURS RANDOMLY AND HAS OCCURRED TWICE WITHIN THE LAST WEEK. I HAVE ALSO HAD TWO TIMES WHERE THE CAR HAS HAD AN INCREDIBLE SURGE FORWARD, SO STRONG THAT MY HEAD WAS THROWN BACK INTO THE HEAD REST. THE SURGE HAS BEEN MOMENTARY AND HAS THE FEELING LIKE GOING UP A STEEP INCLINE ON A ROLLER COASTER WHEN IT FIRST ACCELERATES. BECAUSE THESE EVENTS WERE SUCH A SURPRISE AND SO SHORT IN DURATION I CANNOT RECALL THE CONDITIONS (WHETHER I WAS BRAKING, COASTING, OR ON THE GAS PEDAL) BUT I DO KNOW I WAS GOING AT A SLOW SPEED. I HAVE HAD TWO OCCURRENCES OF THIS SURGE BOTH WITHIN WEEKS OF EACH OTHER IN THE FALL OF LAST YEAR. I TOOK MY CAR INTO THE DEALER REGARDING BOTH OF THE ABOVE ISSUES IN THE FALL OF LAST YEAR, BUT THEY COULD NOT GET THE CAR CREATE EITHER OF THE ABOVE PROBLEMS. AT THAT TIME I ASKED IF THEY HAD ANY SIMILAR COMPLAINTS AND THEY SAID THEY HAD HEARD OF NO OTHER SUCH COMPLAINTS. WHEN THE CAR WAS TAKEN IN TO THE DEALER FOR ROUTINE SERVICE IN NOVEMBER MY HUSBAND AGAIN ASKED ABOUT THE OVERSENSITIVE BRAKING ISSUE AND AGAIN NO PROBLEM WAS FOUND OR SOLUTION PROVIDED. THE OVERSENSITIVE BRAKE AND THE SURGE CREATE PHYSICALLY AND EMOTIONALLY UNCOMFORTABLE CONDITIONS. NO DAMAGE HAS OCCURRED BECAUSE OF THESE PROBLEMS. I HAVE DRIVEN THE CAR WITH UNDER THESE CONDITIONS FIGURING UNTIL THERE ARE COMPLAINTS IT WOULD BE HARD TO RECREATE THESE PROBLEMS AT THE SHOP. WHEN I FIRST TOOK MY CAR IN TO ADDRESS THESE ISSUES I TOLD THE DEALER IT FELT LIKE IT WAS A COMPUTER GLITCH OR ELECTRONIC PROBLEM RATHER THAN MECHANICAL. AND ASKED IT MIGHT SHOW UP ON THE CARS COMPUTER DIAGNOSIS SYSTEM. *TR

REGARDING MY 2010 TOYOTA PRIUS: BRAKES DID NOT ENGAGE. IT WAS RAINING; I WAS SLOWING TO MAKE A RIGHT TURN INTO A PARKING LOT AND MERGED INTO THE TURN LANE, APPLIED THE BRAKES JUST PRIOR TO DRIVING OVER A DRAINAGE GRATE, AND CAR'S BRAKES DID NOT RESPOND. I RELEASED MY FOOT FROM THE BRAKE PEDAL AND THEN RE-ENGAGED IT, WHEREAS THE BRAKES RESPONDED. INCIDENTS VERY SIMILAR TO THIS HAPPENED TWO PRIOR TIMES WHEN BACKING OUT OF MY DRIVEWAY (NOT RAINING). THE BRAKE WARNING LIGHT ALSO GOES ON UNEXPECTEDLY WHILE IDLING AT A TRAFFIC LIGHT OR WHEN COASTING TO A STOP (NOT STOPPING SUDDENLY). WHEN THIS HAPPENS, I HAVE TO PLACE THE CAR INTO PARK AND THEN BACK INTO DRIVE. I INQUIRED ABOUT THESE ISSUES WITH THE TOYOTA DEALER AND HAVE BEEN ADVISED THAT THEY HAVE HAD NO COMPLAINTS OF THIS NATURE WITH THEIR 2010 PRIUSES. *TR

I BOUGHT A 2010 TOYOTA PRIUS IN AUGUST 2009. AFTER HEARING ON THE RADIO AND TV THIS WEEK ABOUT OTHER BUYERS EXPERIENCING THE SAME BRAKING ISSUE I HAVE BEEN OCCASIONALLY EXPERIENCING, I DECIDED TO LET YOU KNOW IT'S HAPPENING TO ME TOO. NAMELY, THERE IS A MOMENT WHEN I AM BRAKING AT A SPEED OF ABOUT 15-25 MPH, IN PREPARATION TO SLOW DOWN FOR A RIGHT TURN AT ONE PARTICULAR INTERSECTION--IT HAS A LARGE POTHOLE. IF I ROLL OVER THE POTHOLE WITH MY FRONT RIGHT TIRE, THE CAR SEEMS TO SPEED UP FOR A FEW SECONDS--INSTEAD OF SLOWING DOWN--AND THERE IS NOTHING THAT APPLYING MORE BRAKE PRESSURE CAN DO. SOMETIMES I'VE NOTICED THIS KIND OF PROBLEM WHEN TRYING TO SLOW DOWN ON A PATCH OF BLACK ICE, BUT THAT SEEMS TYPICAL OF THE DIFFICULTY OF BRAKING ON BLACK ICE. THE POTHOLE ISSUE HAPPENS INVARIABLY AT THAT PARTICULAR POTHOLE, SO I HAVE HAD TO SWERVE TO AVOID ROLLING OVER IT. THERE ARE OTHER POTHOLES THAT I'VE NOTICED CAN CAUSE ME THIS PROBLEM, BUT NONE WITH SUCH FREQUENCY AS THAT. THE GROUND IS LEVEL THERE, SO IT'S NOT A DOWNHILL PROBLEM. *TR

I DRIVE A 2010 TOYOTA PRIUS. ON MULTIPLE OCCASIONS WHILE ATTEMPTING TO SLOW DOWN ON ROUGH SURFACES, THE BRAKES TEMPORARILY STOPPED WORKING FOR 1-2 SECONDS EVEN THOUGH THE BRAKE PEDAL WAS DEPRESSED. THE MOST RECENT INCIDENT OCCURRED WHILE EXITING THE HIGHWAY AND ATTEMPTING TO SLOW DOWN QUICKLY ON ROUGH PAVEMENT. LUCKILY, THERE WERE NO OTHER CARS IN FRONT OF ME OR THERE WOULD HAVE BEEN A COLLISION. IF A CAR HAD BEEN IN FRONT OF ME ON ANY OF THE OCCASIONS THEN THERE WOULD HAVE LIKELY BEEN A COLLISION. *JB

I OWN A 2010 TOYOTA PRIUS II. I'VE NOTICED THAT WHEN I RUN OVER A BUMP OR A POTHOLE ON THE ROAD, THE CAR SEEMS TO ACCELERATE OR JOLT FORWARD. IT HAPPENS WHILE I BRAKE TO A STOP SIGN AND RUN OVER A BUMP OR POTHOLE. IT HAS ALSO HAPPENED WHILE LETTING GO OF THE GAS PEDAL BUT NOT STEPPING ON THE BRAKE. THEREFORE, I HAVE TO QUICKLY STEP ON THE BRAKE EVEN HARDER TO STOP OR SLOW DOWN THE CAR. DURING ONE INCIDENT, I NEARLY RAN INTO A PEDESTRIAN CROSSING THE STREET. IT WAS A 4 WAY STOP AND I APPROACHED SLOWLY. THE PEDESTRIAN WAS DIRECTLY IN FRONT OF MY VEHICLE AND HE HAD THE RIGHT OF WAY. I SLOWLY APPROACHED AND AS MY TIRE RAN OVER THE PAINED "STOP" ON THE PAVEMENT, MY VEHICLE JOLTED FORWARD. IT WAS A CLOSE CALL AND IT SCARED THE PEDESTRIAN AND MYSELF. I WENT TO A TOYOTA DEALERSHIP AND HAS ASKED ABOUT THE PROBLEM. THEY SAID THEY DON'T OR HAVE NOT HAD ANY COMPLAINTS. TOLD ME THAT MINE WAS PROBABLY AN ISOLATED INCIDENT. I WENT HOME AND GOOGLED TO SEE IF OTHER PRIUS DRIVERS HAD THE SAME EXPERIENCE. I WAS SHOCKED TO HAVE READ A FEW INCIDENTS OF OTHER PRIUS OWNERS EXPERIENCING THE SAME THING. WHAT CAN I DO ABOUT THIS MATTER IF TOYOTA CLAIMS THAT MY EXPERIENCE WAS ISOLATED. GOING BACK TO THE TOYOTA DEALERSHIP WON'T RESOLVE ANYTHING. *TR

I HAVE A 2010 TOYOTA PRIUS THAT HAS OFTEN QUIT BRAKING WHEN I WAS DRIVING ON (A) A BUMPY DIRT ROAD (2 TIMES), (B) BUMPY PAVED ROAD (BUMPS CAUSED BY COMPACTED SNOW) (2 TIMES) AND (C) A LARGE DIP IN A ROAD NEAR MY HOUSE (APPROX.10 TIMES). THE LAPSE IN BRAKING IS PROBABLY LESS THAN A SECOND, BUT SCARES ME EVERY TIME. BEFORE MY PRIUS, I HAVE ALWAYS OWNED ALL-WHEEL DRIVE VEHICLES, AND I JUST ATTRIBUTED THE LACK OF BRAKING ON THE FACT THAT I NO LONGER HAVE ALL WHEEL DRIVE. BUT NOW THAT I THINK ABOUT IT. THAT SHOULDN'T AFFECT THE BRAKING! I CAN PRETTY MUCH COUNT ON THIS HAPPENING OVER A BUMPY ROAD, OR JUST ONE BIG BUMP, SO IF SOMEONE WANTS TO DRIVE MY CAR AND SEE WHAT IT DOES, THAT IS FINE WITH ME. LET ME KNOW IF I CAN HELP GET THIS PROBLEM FIXED. I HAVE NOT CONTACTED THE DEALER ABOUT THIS. SHOULD I? *TR

2010 TOYOTA PRIUS. GOING DOWNHILL AND APPROACHING A STOP SIGN. MY FOOT IS STEADY ON THE BRAKE AND I AM GRADUALLY COMING TO A STOP. THEN, I INADVERTENTLY GO OVER A BUMP IN THE ROAD AND THE PRIUS LUNGES FORWARD. I HAD TO IMMEDIATELY SLAM HARD ON THE BRAKES IN ORDER TO KEEP THE CAR FROM GOING INTO THE INTERSECTION.

LISTED ONE DATE, BUT NOT A SINGLE INCIDENT - HAS HAPPENED SEVERAL TIMES SINCE I PURCHASED CAR IN AUG 2009. WHEN BRAKING AND HIT A POTHOLE OR BUMP IN THE ROAD, CAR ACCELERATES/JERKS FORWARD FOR A MOMENT. I HAVE BEEN LUCKY SO FAR THAT I HAVEN'T BEEN CLOSE TO ANOTHER CAR OR A PEDESTRIAN WHEN THIS HAS HAPPENED - THOUGH I CAME VERY CLOSE TO HITTING THE BACK OF ONE CAR THAT STOPPED QUICK IN FRONT OF ME WHEN THIS HAPPENED. *TR

I WAS DRIVING THIS MORNING AND HIT SMALL POT HOLE AS I WAS TRYING TO SLOW DOWN AFTER GOING OVER THE POT HOLE, THE BRAKE DID NOT SEEM TO WORK FOR A BRIEF MOMENT, BUT IT SEEM OKAY LATER ON. *TR

I HAVE A 2010 PRIUS. WHEN I BRAKE OVER A BUMPY SURFACE, I LOOSE BRAKING POWER FOR 1-2 SECONDS. I HAVE EXPERIENCED THIS VERY SERIOUS PROBLEM AT LEAST 10 TIMES. I NOTICED THIS PROBLEM SOON AFTER THE PURCHASE AND CONTINUES. I HAVE BROUGHT IT BACK FOR SERVICE AT TOYOTA BUT I WAS TOLD THERE WAS NO REPORTED PROBLEMS AND THEY COULD NOT FIND THE PROBLEM WHEN THEY ROAD TESTED MY CAR. THIS IS DOCUMENTED IN THE MAINTENANCE RECORDS. A COUPLE OF TIMES WHEN I EXPERIENCED THIS PROBLEM, I ALMOST HIT THE CAR IN FRONT OF ME! THERE IS A DEFECTIVE BRAKING SYSTEM. *TR

I HAVE NOT YET HAD THIS PROBLEM CORRECTED, BUT WHEN I DECELERATE IN MY 2010 TOYOTA PRIUS AND I HAPPEN TO GO OVER A BUMP (CAN BE A POTHOLE, OR ICE, ETC.), IN ALL WEATHER CONDITIONS, THE BRAKE SOMETIMES DISENGAGES BRIEFLY AND I HAVE TO RE-ENGAGE TO RE-ESTABLISH BRAKING. THE LOSS OF BRAKING IS UNRELATED TO THE POSITION OF MY FOOT, IT'S AS IF THE BRAKE SUDDENLY IS NOT PRESENT (NOT A DECREASE IN BRAKE PRESSURE). I'VE CAUGHT IT QUICKLY EACH TIME, SO NEVER THOUGHT TO COMPLAIN UNTIL THE RECENT RECALLS. *TR

I DRIVE A 2010 TOYOTA PRIUS. I HAVE FOUND ON MULTIPLE TIMES (5-10), WHILE BRAKING, THE CAR SEEMS TO ACCELERATE FOR A BRIEF PERIOD OF TIME (1 SECOND) THEN BEGIN TO BRAKE. THIS ONLY HAPPENS ON BUMPY ROADS. IT HAS HAPPENED EVER SINCE I PURCHASED THE VEHICLE IN OCT 2009. *TR

I GOT INTO A WRECK WHEN DRIVING MY 2010 TOYOTA PRIUS BECAUSE I FEEL THE BREAKS DID NOT WORK PROPERLY. THE DRIVER IN FRONT OF ME SLAMMED ON HIS BRAKES AND I SLAMMED ON MINE, I WAS IN THE MIDDLE OF A 3 CAR PILEUP. I DID NOT RECEIVE A CITATION BECAUSE I WAS NOT FOLLOWING TO CLOSE, WHICH LEADS ME TO BELIEVE THE BREAKS WERE NOT WORKING AS GOOD AS THEY SHOULD HAVE. I AM IN INDUSTRIAL ENGINEER AND I BELIEVE THIS IS MOST LIKELY A COMPUTER PROBLEM. I DROVE A HONDA CIVIC FOR 13 YEARS AND THE BREAKS WERE MUCH SHARPER, ONCE ACTIVATED THEY STOPPED THE CAR MUCH FASTER. I NEVER GOT INTO A WRECK WITH MY CIVIC, HOWEVER, AFTER OWNING MY PRIUS FOR ONLY 2 WEEKS I GOT INTO A WRECK. THE INCIDENT NUMBER PROVIDED BY THE OKLAHOMA CITY POLICE DEPARTMENT IS 102719. *TR

I HAVE A 2010 TOYOTA PRIUS III, PURCHASED IN JUNE 2009, AND HAVE BEEN EXPERIENCING BRAKE PROBLEMS FOR THE PAST SEVERAL MONTHS. IF WHILE BRAKING I HAPPEN TO HIT A BUMP IN THE ROAD MY BRAKES FAIL FOR A BRIEF MOMENT CAUSING THE CAR TO SPEED UP RATHER THAN SLOW DOWN. IN ORDER TO STOP THE SUDDEN ACCELERATION I HAVE TO PUSH THE BRAKE PEDAL DOWN EVEN FURTHER WITH MORE PRESSURE AND/OR QUICKLY LIFT MY FOOT AND BRAKE AGAIN. THIS FAILURE HAPPENS FAIRLY CONSISTENTLY IF THE CONDITIONS ARE CORRECT. THE SIZE OF THE BUMP IN THE ROAD DOES NOT SEEM TO MATTER AS THE BRAKE "FAILURE" HAS HAPPENED WITH EVERYTHING FROM A SMALL POTHOLE TO RAILROAD TRACKS. THE FAILURE SEEMS TO LAST ONLY A MATTER OF SECONDS, BUT IT'S ENOUGH TO POSSIBLY CAUSE AN ACCIDENT ESPECIALLY WHILE IN A HIGH TRAFFIC SITUATION. I DIDN'T START TO NOTICE THIS PROBLEM UNTIL CLOSE TO A MONTH INTO OWNERSHIP OF THE VEHICLE BUT HAVE BECOME INCREASINGLY AWARE OF IT EVERY TIME IT HAPPENS. I HAVE CALLED MY LOCAL TOYOTA DEALER AND FILED A COMPLAINT WITH THEM DURING MY LATEST SERVICE APPOINTMENT ON 1/19/10 SINCE I EXPERIENCED THE FAILURE WHILE ON MY WAY TO THE DEALERSHIP, BUT THEY SAID THEY WERE UNABLE TO REPLICATE THE PROBLEM. *TR

I OWN A 2010 TOYOTA PRIUS AND HAVE NOTICED SEVERAL ISSUES WHEN BRAKING. ON NUMEROUS OCCASIONS I HAVE NOTICED THAT WHEN I AM BRAKING AND HIT A POTHOLE (OR ANY FORM OF DIP IN THE ROAD) MY CAR SEEMS TO LUNGE FORWARD (I.E., ACCELERATE) UNTIL THE TIRES ARE BACK ON LEVEL PAVEMENT. ONE OF THE MORE FRIGHTENING INCIDENTS OCCURRED THIS PAST JANUARY. IT WAS BELOW FREEZING OUTSIDE, BUT THERE HAD BEEN NO PRECIPITATION. HOWEVER, THERE WAS ONE AREA NEAR A RED LIGHT WHERE THE SPRINKLERS HAD BEEN LEFT ON OVERNIGHT. THIS AREA HAD TURNED INTO A SMALL SECTION OF ICE. I CAME UP TO THE INTERSECTION AND BEGAN TO BRAKE WHEN I HIT THIS SPOT. THE BRAKES SEEMED TO MALFUNCTION, BUT IT WASN'T AS IF I WAS SKIDDING ON THE ICE. RATHER, I COULD FEEL THE CAR LUNGING FORWARD AGAIN AS IT DOES WHEN IT HITS A POTHOLE. I HEARD ON NPR THAT OTHER PRIUS OWNERS ARE EXPERIENCING SIMILAR ISSUES SO I WANTED TO LODGE A COMPLAINT TO ENSURE THAT THIS GETS THE PROPER ATTENTION. *TR

Mileage: 3,500

SOMETIMES WHEN DEPRESSING THE BRAKE THERE IS A BRIEF PERIOD OF TIME (.5 SEC, OR SO) WHERE THE BRAKES STOP WORKING. IT FEELS AS THOUGH THE BRAKES ARE SLIPPING - LETTING UP JUST ENOUGH TO LET THE CAR CONTINUE ROLLING WITHOUT ANY RESTRICTION. THIS HAS HAPPENED TO ME ROUGHLY 5 TIMES SINCE I PURCHASED THE VEHICLE IN JULY OF 2009. *TR

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

FROM AUGUST 1ST OF 2009, I HAD BEEN DRIVING A 2010 PRIUS. IT IS A GREAT VEHICLE FOR ECONOMY BUT THERE IS A PROBLEM WITH BRAKES. WHEN BRAKES ARE APPLIED AND IF THERE IS A BUMP, THE VEHICLE JUMPS FORWARD OR ACCELERATES AND THE STOPPING DISTANCE INCREASES. USUALLY A SAFE DISTANCE BEHIND A VEHICLE IS WHEN THE TAIL PIPE OF THE VEHICLE IN FRONT OF YOU IS VISIBLE. WITH THE PRIUS, TO BE SAFE, I STOP AT LEAST TEN FEET BEHIND A VEHICLE BECAUSE IF THERE IS A BUMP, THE VEHICLE WILL JUMP FORWARD. *TR

THE BRAKES ON MY 2010 TOYOTA PRIUS FAILED DURING HEAVY TRAFFIC ON THE SOUTH 405 FREEWAY IN LOS ANGLES NEARLY CAUSING AN ACCIDENT. I ALMOST REAR ENDED A NISSAN 370 ZX. IN GENERAL THE BRAKES SEEM SUBSTANDARD AND FEEL MUSHY AFTER DRIVING IN TRAFFIC OR ESPECIALLY RAIN AS WE HAVE BEEN HAVING IN CALIFORNIA. I AM CONCERNED ABOUT THE BRAKES ON THE CAR AND HAVE STARTED SHOPPING FOR ANY UPGRADE KITS THAT MIGHT BE AVAILABLE. THE BRAKE FAILURE WAS VERY UNSETTLING AND I READ REPORTS TODAY ABOUT OTHER PRIUS DRIVERS COMPLAINING AS WELL. THEREFORE I FELT THAT I SHOULD FILE A COMPLAINT TO ENSURE THAT THE BRAKES ARE LOOKED INTO BY TOYOTA. *TR

THIS HAS OCCURRED SEVERAL TIMES (AT LEAST HALF A DOZEN TIMES) SINCE I'VE PURCHASED MY NEW 2010 TOYOTA PRIUS IN JULY 2009. WHILE DRIVING AT LOW SPEEDS (~20 MPH), THE BRAKES HAVE MOMENTARILY STOPPED WORKING (CAUSING THE VEHICLE TO SURGE FORWARD) AFTER DRIVING OVER A POTHOLE OR SIMILAR OTHER UNEVEN SURFACE. I HAVE TRIED TO ADJUST HOW I DRIVE, IN AN EFFORT TO AVOID THE SURPRISE OF THE SURGE, AND POTENTIAL ACCIDENTS, RELATED TO THIS BRAKING PROBLEM. I HAVE NOT YET SOUGHT A REPAIR FROM TOYOTA. *TR

THIS IS A RECURRING PROBLEM WITH MY 2010 PRIUS. WHEN I GO OVER A SMALL BUMP, SUCH AS A METAL PLATE ON THE STREET, SO FAR ALWAYS AT LOW SPEED IT FEELS AS THOUGH THE CAR ACCELERATES. I THINK IT'S PROBABLY JUST NOT BRAKING THE WAY I EXPECT IT TO, OR PERHAPS THE BRAKES MOMENTARILY FAIL. IT LASTS LESS THAN A SECOND, AND OF COURSE I WAS WORRIED THAT IT REPRESENTS THE SAME PROBLEM THAT HAS CAUSED THE BIG TOYOTA RECALL. BUT I THINK IT'S DIFFERENT. THERE'S AN ARTICLE IN TODAY'S NEW YORK TIMES ABOUT THIS. *TR

Mileage: 6,000

WHILE DRIVING AT A NORMAL SPEED (20 - 60MPH), I START SLOWLY PUSHING ON THE BRAKE PEDAL EACH TIME I RUN OVER A POTHOLE OR A BUMP IN THE ROAD, AND FOR A SPLIT SECOND I FEEL THE CAR ACCELERATE SLIGHTLY EVEN THOUGH I AM BRAKING. I HAVE NOTICED THIS 95% OF TIMES I GO OVER A POTHOLE AND PROBABLY IN A FEW OTHER SITUATIONS AS WELL (POSSIBLY WHEN DRIVING ON SLICK OR ICY ROADS). I HAVE NOT COMPLAINED ABOUT THIS BEFORE, SO NOTHING HAS BEEN DONE ABOUT THE FAILURE. *TR

SOMETIMES THE BREAKS DO NOT TAKE HOLD WHEN I PRESS THE BRAKE PEDAL AND THE CAR SEEMS TO SKIP FORWARD FOR A SECOND OR TWO BEFORE IT BEGINS TO SLOW DOWN AND THE BRAKES TAKE HOLD. IT IS VERY UNSETTLING BUT I HAVE NOT HAD AN ACCIDENT. MY WIFE WILL NOT DRIVE THE CAR. I REPORTED IT TO THE SERVICE MANAGER AT MY DEALER, SEEGER TOYOTA IN ST. LOUIS COUNTY, MISSOURI. HE SAID HE KNEW OF NO COMPLAINTS LIKE THIS WHATSOEVER.

2010 PRIUS, WITH NO MODIFICATION MADE SINCE PURCHASE. WHEN DRIVING AND COMING TO A STOP, THE BRAKE PEDAL WAS APPLIED TO STOP THE CAR. THE CAR HIT A POTHOLE/SHARP BUMP 5 FEET BEFORE THE STOP SIGN AND THE CAR JERKED FORWARD FRIGHTENINGLY WHILE THE BRAKE WAS DEPRESSED. THE BRAKE PEDAL LOST ITS BREAKING ABILITY FOR 1 OR 2 SECONDS, BUT BECAME OPERATIONAL AGAIN AFTER THAT. DURING THE 1 OR 2 SECONDS, I FELT I LOST CONTROL OF THE CAR. THIS DEFECT IS REPRODUCIBLE AND HAS OCCURRED 5 TIMES SINCE I BOUGHT THE CAR 6 MONTHS AGO. THIS IS VERY SCARY AND I THINK WILL CAUSE AN ACCIDENT IF NOT FIXED. *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.

TOYOTA-PRIUS HYBRID-2010 BRAKING PROBLEM. I HAVE EXPERIENCE A BRAKING PROBLEM THAT HAS NOT RESULTED IN AN ACCIDENT. THE BRAKING PROBLEM RESULTS ONLY WHEN IN A PANIC STOP (WHEN ABS IS ACTIVE). I THINK WHAT IS HAPPENING IS THAT THE BRAKE IS RELEASING FOR A SECOND WHILE THE ABS COMPUTER IS TAKING OVER CONTROL OF THE BRAKING. THIS CAUSE WHAT SEEMS TO THE DRIVE AS A SLIP. WHERE THE DRIVE FEELS THE BRAKE RELEASE AND A SECOND LATER THE ABS KICKS IN AND STOPS THE CAR. I HAVE FELT THIS BRAKE RELEASE THREE TIMES IN THE FEW MONTHS I HAVE OWNED THE CAR AND MOST TIMES WHEN TURNING RIGHT INTO A DRIVEWAY. *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.

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 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.

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.

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

OCCASIONALLY WHEN BRAKING AT A RELATIVELY SLOW SPEED ON A BUMPY OR SLIPPERY SURFACE THE BRAKES FEEL LIKE THEY STOP WORKING. MY IMMEDIATE RESPONSE IS TO PRESS THE BRAKES HARDER AND THAT SEEMS TO RESOLVE THE ISSUE. I DON'T REMEMBER ANY SENSE THAT THE ABS SYSTEM KICKED IN DURING THESE SITUATIONS. I HAVE NEVER NOT PRESSED HARDER ON THE BRAKE PEDAL SO DON'T KNOW WHETHER THE LOSS OF BRAKING SENSATION WOULD CONTINUE IF NO MORE PRESSURE WAS APPLIED TO THE BRAKES. I HAVE ALSO FELT THIS SENSATION WHEN BRAKING WHILE CORNERING AT SLOWER SPEEDS. I DON'T KNOW IF A SLIPPERY OR BUMPY SURFACE IS ALWAYS INVOLVED WHEN I EXPERIENCE THE LOSS OF BRAKING WHILE TURNING, BUT AT LEAST ON ONE OCCASION DURING CORNERING THERE HAS BEEN A BUMP GOING FROM A SLIGHTLY RAISED ASPHALT SURFACE TO LOWER CONCRETE SURFACE ATTACHED TO THE CURB FOR THE PASSENGER SIDE WHEEL ONLY. *TR

DEAR, NHTSA I WAS DRIVING MY PRIUS IN NOVEMBER OF 2010 AND NOTICED THAT THE BRAKING SYSTEM WAS NOT BRAKING WELL. I RECENTLY WAS INVOLVED ON JAN 29, 2010 IN AN INCIDENT DRIVING OUT OF THE PARKING LOT FROM WORK WERE THE BRAKES FAILED ON THE VEHICLE WHEN I WENT TO STOP THE VEHICLE AND THE CAR SKIDDED AND STRUCK SOME ICE/SNOW (ONE THE EDGE OF THE PARKING LOT) CAUSING DAMAGE TO MY FRONT PASSENGER SIDE BUMPER. I AM NOT AS CONCERNED ABOUT THE DAMAGE AS I AM ABOUT MY OVERALL SAFETY IN THE VEHICLE. I HAVE REPORTED THE PROBLEM TO TOYOTA AND THEY HAVE RESPONDED AND I HAVE TOLD THEM THAT THERE IS AN ISSUE WITH THE BRAKING. I WANT TO TAKE THIS TIME TO FORMALIZE MY COMPLAINT. I AM NOT CHECKING CRASH AND PROPERTY DAMAGE DUE TO THE FACT THAT IT IS NOT WELL DEFINED ON THIS PAGE ALTHOUGH I HAD PROPERTY DAMAGE TO THE CAR ITSELF AND I CRASHED INTO SNOW/ICE ON THE SIDE OF THE ROAD. *TR

I PURCHASED A 2010 TOYOTA PRIUS ON DEC. 23 2009 IN COLUMBUS OH, AND EXPERIENCED BRAKE PROBLEM TWICE. WHEN I WAS COMING OUT OF MY STREET TO MERGE TO A BIGGER STREET, I USED THE BRAKE TRYING TO STOP THE CAR. INSTEAD OF COMING TO A STOP, THE CAR JUMPED FORWARD.

WE HAVE HAD SEVERAL INSTANCES OF BRAKE MALFUNCTION IN OUR 2010 PRIUS. WHEN BACKING OUT OF OUR GARAGE, ON 3 OCCASIONS, WHEN MY FOOT WAS JUST RESTING GENTLY OVER THE BRAKE, IT FELT AS THOUGH I WAS STOMPING ON THE BRAKE. IT DID THIS 4-5 TIMES WHERE IT LURCHED TO A STOP WHEN I WASN'T APPLYING IT BUT JUST RESTING MY FOOT ON IT AS I BACKED UP. I HAD AN INCIDENT WHERE I WAS ENTERING A CAR WASH AND WHEN I WENT OVER A BUMP INTO THE CAR WASH STALL, THE CAR LURCHED UNCONTROLLABLY FORWARD. I TRIED TO PUT THE CAR INTO NEUTRAL AND IT WOULDN'T STAY IN NEUTRAL BUT KEPT POPPING BACK INTO DRIVE AN LURCHING FORWARD.. ALSO, WE HAVE 3 INCIDENTS IN INCLEMENT WEATHER WHERE THE ANTI-LOCK BRAKES DID NOT WORK AT ALL OR DID NOT WORK CORRECTLY. ON A SNOWY DAY, I SLID RIGHT THROUGH AN INTERSECTION AND THE ANTI LOCK BRAKES DID NOT KICK IN NOR DID THE ANTI-LOCK BRAKE INDICATOR LIGHT COME ON. MY HUSBAND HAD AN INCIDENT WHERE IF FELT AS THOUGH THE ANTI-LOCK BRAKES FUNCTIONED ONLY ON ONE SIDE OF THE CAR, PROPELLING HIM STRAIGHT SIDEWAYS UPON BRAKING. WE FEEL VERY STRONGLY THAT THERE IS A PROBLEM WITH THIS MODEL OF PRIUS THAT POSES A SIGNIFICANT RISK TO OUR SAFETY. *TR

I TOOK IT TO THE DEALERSHIP TODAY AND THEY CHECKED THE CAR AND SAID THEY COULDN'T FIND ANYTHING WRONG WITH IT. THEY ALSO SAID THEY HAD NO KNOWLEDGE OF ANY KIND OF BRAKING OR SURGING PROBLEMS WITH THIS VEHICLE. OUR DEALER WAS EASTERN SHORE TOYOTA IN DAPHNE, AL.

SPORADIC PROBLEMS WITH THE BRAKES ON OUR 2010 TOYOTA PRIUS. WE HAVE DISCUSSED THIS SEVERAL TIMES ON CHAT BOARDS OVER THE PAST FIVE MONTHS. IT HAPPENS PERHAPS ONCE A MONTH. THE BRAKES LOCK WHEN THE CAR IS IN REVERSE. BACKING OUT OF THE GARAGE, YOU CAN JUST BARELY TOUCH THE BRAKES AND IT'S AS THOUGH YOU HAD SLAMMED THE FULL FORCE OF YOUR FOOT ON THE BRAKES. LITERALLY CAN CAUSE WHIPLASH EVEN AT THE SLOW SPEED OF BACKING OUT. WHEN THIS PROBLEM OCCURS IT WILL OCCUR OVER AND OVER AS LONG AS YOU ARE IN REVERSE. EACH TIME WHEN YOU SLIGHTLY DEPRESS THE BRAKES, THE CAR SLAMS TO A COMPLETE STOP. WHAT WE HAVE FOUND IS THAT THE ONLY WAY TO CORRECT IT, HAS BEEN TO TURN OFF THE CAR COMPLETELY AND RE-START THE CAR. IT MAY JUST BE COINCIDENCE, BUT TYPICALLY THE BRAKES RETURN TO COMPLETELY NORMAL OPERATIONS IN REVERSE AFTER THE IGNITION HAS BEEN SHUT OFF AND THE VEHICLE ENGINE RESTARTED. THE GREATEST ODDITY IS THAT IT APPEARS THAT THE BRAKES DO NOT RESPOND IN THE SAME DEGREE AS THE BRAKES ARE DEPRESSED. IT'S AS THOUGH THE BRAKES WHEN DEPRESSED EVEN SLIGHTLY MESSAGE THE CAR TO EXERT FULL BRAKING ACTION. IT'S THE ONLY CAR WE'VE EVER OWNED WHERE THE BRAKING POWER SEEMS NOT TO BE DEPENDENT ON THE DEGREE WITH WHICH WE PRESS THE BRAKES. AGAIN, THIS DOESN'T HAPPEN EVERY TIME WE HAVE THE CAR IN REVERSE, BUT TYPICALLY BETWEEN ONCE A MONTH AND EVERY SIX WEEKS. *TR

WHEN THE CAR IS MODERATELY BRAKING (SO CALLED REGENERATIVE BRAKING) AND EITHER (OR BOTH) OF THE REAR WHEELS HITS ROUGH PAVEMENT (POT HOLES, METAL PLATES COVERING ROAD, ROUGH RAIL-ROAD CROSSINGS) THE CAR CEASES TO BREAK AND THE CAR ACTUALLY ACCELERATES (THE ACTUAL TIME IS ABOUT 1 SECOND OF NO BREAKS AND ACCELERATION). I HAVE HAD THIS HAPPEN 10 TIMES SINCE I BOUGHT THE CAR IN OCT OF 09. IN THE FIRST MONTH THE DEALER TOLD ME THEY HAD NOT HEARD OF THIS. TWO MONTHS AGO (DEC)A MECHANIC TOLD ME THAT THE ELECTRIC ENGINE KICKS IN (WHEN REGENATIVE BREAKING) WHICH DRIVES THE FRONT WHEELS FOR A SMOOTHER BREAKING, SO HE SURMISED THAT IF THE BREAKING WHEELS ARE NOT MAKING CONTACT THE CAR WOULD SPEED UP. ON 1/13/2010 I MET WITH THE HEAD OF SERVICE FOR THE DEALERSHIP. HE TOLD ME THAT THE DEALERSHIP TESTED A PRIUS HOOKING IT UP TO A COMPUTER AND REPRODUCED THE ENVIRONMENT OF THIS COMPLAINT. ALTHOUGH HE ADMITTED THERE WAS A MOMENTARY LACK OF BREAKING WITH THE LOSS OF BACK WHEEL CONTACT WITH THE PAVEMENT HE CLAIMED THERE WAS NO ACCELERATION NOTED. HE ALSO ADMITTED THE TEST WAS DONE AT APPROX. 25MPH. I SUGGESTED HE SHOULD REPEAT THE TEST AT 40-50MPH AS THIS IS WHERE IT IS MOST NOTABLE. TOYOTA'S ONLY SUGGESTION IS TO DRIVE CAREFULLY. THEY KNOW THEY HAVE A PROBLEM BUT THIS IS THERE SOLUTION. I HAVE BEEN CAREFUL BUT ON 1/31/10 I WAS DRIVING AT 45MPH BEGINNING TO DECELERATE AS THE LIGHT AHEAD HAD TURNED RED, AND THE TRUCK INFRONT OF ME HAD TO PANIC STOP AS A CAR CUT INFRONT OF HIM, AT THAT MOMENT MY REAR LEFT WHEEL HIT A POTHOLE SO I WAS NOT ABLE TO BRAKE AND ACTUALLY ACCELERATED TOWARD THE BACK OF THIS TRUCK. WHEN THE BRAKES REENGAGED I ACTUALLY STOPPED 12 INCHES FROM HIS BUMPER. THE CONSEQUENCES OF THIS ARE AN OBVIOUS SAFETY HAZARD WHEN YOU NEED TO STOP UNEXPECTEDLY, YOU MIGHT WELL BE ENDANGERING OTHER DRIVERS AND/OR PEDESTRIANS. *TR

ON ROUGH ROADS AND TERRAIN, THE 2010 PRIUS THAT I RECENTLY BOUGHT CONSISTENTLY DISPLAYS DEFECTIVE BEHAVIOR. WHEN I AM TRYING TO BRAKE, AND DURING BRAKING HIT A BUMP (ALWAYS DURING A SLOW BRAKE), THE CAR ACTUALLY SPEEDS UP. THIS HAS RESULTED IN MY CHANGING MY DRIVING HABITS TO BE FURTHER AWAY FROM CARS IN FRONT OF ME, ESPECIALLY ON BUMPY ROADS. HOWEVER, I AM VERY CONCERNED THAT AT SOME POINT I WON'T BE ABLE TO STOP THE VEHICLE PROPERLY WHEN EXPECTING THE CAR TO CONTINUE A SLOW BRAKE, AND INSTEAD IT HITS A BUMP AND DOES NOT BRAKE. I DON'T BELIEVE TOYOTA IS ADDRESSING THE DEFECT AT THIS TIME FROM REPORTS I HAVE READ. MY MOTHER (WITHOUT GOING INTO ANY DETAIL AFTER HAVING READ REPORTS) ASKED IF I HAD EXPERIENCED ANY ISSUES WITH MY PRIUS AND I TOLD HER OF THIS EXACT ISSUE PRIOR TO BEING AWARE OF MEDIA COVERAGE. *TR

I OWN A 2010 TOYOTA PRIUS. ON A NUMBER OF OCCASIONS IT FEELS AS THOUGH THIS VEHICLE HAS LOST BRAKING FORCE FOR A BRIEF PERIOD OF TIME (NO MORE THAN 1 SECOND) WHEN THE VEHICLE ENCOUNTERS AN UNEVEN ROAD SURFACE WHILE BRAKING. I BELIEVE THIS ONLY HAPPENS WHILE THE VEHICLE IS USING REGENERATIVE BREAKING. WHEN THIS HAPPENS THE VEHICLE FEELS LIKE IT'S LURCHING FORWARD BECAUSE THE BRAKING FORCE HAS BEEN REMOVED. ONCE I PRESS HARDER ON THE BRAKES TO FORCE THE FRICTION BRAKES TO APPLY, OR AFTER A BRIEF PERIOD OF TIME, THE CAR DOES CONTINUE TO SLOW DOWN. I HAVE NOT YET HAD AN ACCIDENT OF ANY KIND, BUT I CAN IMAGINE HOW ONE COULD HAPPEN BECAUSE OF THE INCREASED STOPPING DISTANCE. *TR

THERE ARE BRAKING ISSUES WITH MY 2010 TOYOTA PRIUS. 1) IN MULTIPLE INSTANCES, PERHAPS 12 TIMES, WHEN BRAKING IN SNOWY CONDITIONS, THERE IS A MOMENT WHERE THE BRAKES APPEAR TO BE INACTIVE. PRESSING MUCH HARDER BRINGS THE BRAKES BACK ON LINE. I HAVE DRIVEN FOR 40 YEARS, IN DOZENS OF CARS AND NEVER FOUND THIS. THE SITUATION IS COUNTER-INTUITIVE, BECAUSE I DO NOT WANT TO JAM ON THE BRAKES IN SLIPPERY CONDITIONS FOR OBVIOUS REASONS. 2) IN 3-4 INSTANCES WHEN BRAKING AND GOING OVER A POTHOLE OR LARGER BUMP, THE SAME AS THE ABOVE OCCURS, THAT IS MOMENTARY LOSS OF BRAKING. AGAIN, PRESSING HARDER ALLEVIATES THE PROBLEM. *TR

BASICALLY, AS I START TO BACK UP IT WILL JERK AND THEN THE CAR STOPS AND THEN IT RELEASES AGAIN AND THEN IN A FEW MORE INCHES IT JERKS AGAIN AND THEN RELEASES AND THEN JERKS AGAIN. IT DOES THIS GOING FORWARD TOO. IT DOESN'T HAPPEN EVERY TIME I DRIVE THE CAR BUT IT HAS HAPPENED MAYBE 20 TIMES OR SO IN THE PAST COUPLE MONTHS.

OCCURRING SEVERAL TIMES SINCE PURCHASE IN OCTOBER 2009, I EXPERIENCED A SLIGHT BURST OF ACCELERATION WHEN HITTING A POTHOLE OR SIZEABLE BUMP IN THE ROAD. DURING AN EXIT ONTO A HIGHWAY ACCESS ROAD (20-30 MPH) AND A SLOWING FOR A 90 DEGREE TURN (10-20 MPH) THE CAR EITHER DISENGAGED THE BRAKES OR ACCELERATED CAUSING A VERY BRIEF AND UNEXPECTED LURCH FORWARD. AFTER PASSING THE ROAD IMPERFECTION NORMAL BREAKING RETURNS.

ON NUMEROUS OCCASIONS THE CAR SEEMS TO SURGE WHEN SLOWING DOWN TO STOP AT AN ONCOMING INTERSECTION, STOP LIGHT, OR STOP SIGN. THIS ONLY OCCURS IF THE CAR COMES TO A POT HOLE OR "WASHBOARD" SURFACE IN THE ROAD WHILE IN THE PROCESS OF NORMAL BRAKING. I DON'T BELIEVE THE TRACTION CONTROL IS RESPONSIBLE BECAUSE THE TRACTION LIGHT DOES NOT COME ON WHEN THIS HAPPENS. IT ALSO DOES NOT SEEM TO HAVE ANYTHING TO DO WITH THE ABS BECAUSE THE CAR SEEMS TO SURGE FOR ABOUT A SECOND DUE TO THE TIRE OR TIRES LOOSING TRACTION FOR A SPLIT SECOND. I HAVE DUPLICATED THIS EVENT MULTIPLE TIMES IN THE SAME AREA AND HAVE LEARNED TO ANTICIPATE IT WHEN DRIVING THIS ROUTE. HOWEVER, WHEN IT HAPPENS UNEXPECTEDLY, IT CERTAINLY GETS YOUR ATTENTION. *TR

I'VE BEEN AN EMPLOYEE OF GENERAL MOTORS FOR 25 YEARS AND WORKED IN A DEPARTMENT THAT MADE ANTI LOCK BRAKES FOR 8 OF THOSE YEARS. THIS IS NOT A NORMAL FUNCTION OF THAT FEATURE BY ANY MANUFACTURER.

WHEN I BRAKE MY PRIUS WHERE THE SURFACE IS VERY ROUGH OR BROKEN, THE BRAKES SEEM TO ENGAGE INITIALLY BUT THEN RELEASE.

YESTERDAY, FOR EXAMPLE, WHILE COMPLETING LONG SLOW BRAKING AT THE BOTTOM OF A STEEP HILL, I ENCOUNTERED SOME ROUGH PAVEMENT JUST BEFORE THE STOP SIGN AND SUDDENLY THE BRAKES SEEMED TO RELEASE.

MY NEW 2010 PRIUS HAS A BRAKE PROBLEM. I HAVE OWNED THE CAR ABOUT 2 MONTHS, AND HAVE PUT ABOUT 3000 MILES ON IT. ON THREE OCCASIONS, I HAVE EXPERIENCED A SITUATION WHERE THE BRAKES SUDDENLY RELEASED, AND I HAD TO SLAM ON THE BRAKE PEDAL TO PREVENT AN ACCIDENT. TWO OF THE SITUATIONS HAPPENED WHEN I WAS COMING TO A STOP NEAR AN INTERSECTION (I WAS MOVING INTO A LEFT TURN LANE, AND SUDDENLY THE BRAKES RELEASED). THE THIRD TIME WAS WHILE EXITING A FREEWAY, WHEN I HIT A POTHOLE, AND I FELT THE BRAKE RELEASE. AFTER THE THIRD EXPERIENCE, I RECALLED THAT, PERHAPS, THE CAR RAN OVER A SMALL BUMP WHEN I WAS MOVING INTO THE LEFT TURN LANE, AND THAT MAY HAVE HELPED TRIGGER THE RELEASE OF THE BRAKE PEDAL. I TOOK THE CAR TO THE TOYOTA DEALER WHERE I PURCHASED IT, BUT THEY WERE UNABLE TO FIND ANYTHING WRONG. I SUBSEQUENTLY READ (VIA AN MSNBC NEWS STORY THAT CAME OUT ON DECEMBER 29, 2009, AND WHICH IS AVAILABLE AT THE LINK BELOW) THAT OTHERS ARE HAVING THE SAME PROBLEM THAT I EXPERIENCED.

MY PRIUS STOPS BRAKING AND ALMOST FEELS LIKE IT IS ACCELERATING IF I APPLY THE BRAKE JUST AS I HIT A BUMP OR HOLE IN THE ROAD. THIS FEELS VERY DANGEROUS--IF I WERE NEEDING TO STOP SUDDENLY TO AVOID A POTENTIAL ACCIDENT AND MY BRAKES DID NOT WORK DUE TO A BUMP IN THE ROAD, IT COULD LEAD ME TO CRASH INTO THE OBJECT I'M TRYING TO AVOID. THIS HAS HAPPENED MULTIPLE TIMES IN THE MONTHS SINCE JUNE 09 IN WHICH I BOUGHT MY CAR.*TR

WHEN DRIVING MY NEW 2010 TOYOTA PRIUS III MODEL, I HAVE EXPERIENCED SUDDEN LOSS OF BRAKING WHEN THE CAR HITS A BUMP WHILE BRAKING. FOR EXAMPLE, WHEN APPROACHING A STOP SIGN, I PRESS DOWN ON THE BRAKES, AT WHICH POINT THE CAR BEGINS TO BRAKE, AND THEN THE CAR HITS A SMALL BUMP OR POTHOLE AND THE BRAKES LET UP SUDDENLY AND IT FEELS AS THOUGH I LOSE CONTROL OF THE CAR WHILE STILL APPROACHING THE INTERSECTION. I HAVE TO PRESS DOWN AGAIN HARD ON THE BRAKES IN ORDER TO STOP BEFORE GOING THROUGH THE STOP SIGN AFTER THE BRAKES FAILED ME. LUCKILY, EACH TIME IT HAS HAPPENED I HAVE BEEN ABLE TO STOP IN TIME, HOWEVER I HAVE TO BRAKE VERY HARD IN ORDER TO STOP AND IT IS NOT SMOOTH.

TODAY WHILE WITH MY MOM AND THE KIDS I SLOWED DOWN TO NAVIGATE OVER AN UNAVOIDABLE PATCH OF ICE IN AN INTERSECTION. THANK GOODNESS NO ONE WAS IN FRONT AND THE ONCOMING CAR ATTEMPTING TO TURN LEFT DIDN'T GO BECAUSE I APPLIED THE BRAKE AND WE JUST SAILED ON THROUGH, BARELY MAKING THE TURN THAT I NEEDED TO MAKE JUST BEYOND THE INTERSECTION.

INITIALLY, I CONVINCED MYSELF I MUST HAVE BEEN LETTING UP ON THE BRAKE WHEN I HIT THE BUMP BUT WHEN THIS SAME THING HAPPENED 3 DAYS AGO ON SLIPPERY, ICY ROADS, I KNEW FOR 100% CERTAIN I HAD NOT LET UP ON THE BRAKE. MY CAR SURGED AS I WAS SLOWLY PULLING UP TO A STOP SIGN AND GENTLY BRAKING. I CAME VERY CLOSE TO HITTING THE CAR IN FRONT OF ME, HAD TO PUSH DOWN ON THE BRAKES VERY HARD, WHICH ACTIVATED THE ABS. THE ABS HAD NOT BEEN ACTIVATED IN ANY OF THE PREVIOUS INCIDENTS BECAUSE I HAD NOT NEEDED TO PUSH HARD ON THE BRAKES AS I WAS IN NO DANGER OF HITTING ANYTHING. I HAVE BEEN DRIVING TOYOTAS SINCE 1992 AND AM STUNNED THAT THIS PROBLEM IS HAPPENING WITH NO FIX IN SIGHT. THE DEALERSHIP IN MY TOWN ASSURES US THEY'VE NEVER HEARD OF THIS BEFORE, ALTHOUGH IT IS OBVIOUSLY HAPPENING ALL OVER THE COUNTRY. PLEASE INVESTIGATE THIS. I HAVE A 5 YEAR OLD AND I NO LONGER FEEL SAFE DRIVING MY CAR WITH (OR WITHOUT) HIM IN IT. *TR

MY 2010 PRIUS IS ONLY 2 MONTHS OLD & WHEN APPLYING THE BRAKES, AT TIMES, IT FEELS LIKE I HAVE BEEN HIT IN THE BACK BY ANOTHER VEHICLE AND THE ENTIRE CAR JUMPS FORWARD BEFORE COMING TO A FULL STOP. SOME WHAT LIKE AN ENGINE SURGE OR THAT THE BRAKES HAVE NOT APPLIED PROPERLY. I HAVE REPORTED THIS TO MY TOYOTA SERVICE DEPARTMENT & THEY HAVE SUGGESTED THAT MAYBE IT IS DUE TO THE GAS ENGINE TURNING ON OR OFF AT THAT EXACT MOMENT. I FIND THIS TO BE VERY DANGEROUS AS THERE IS A DEFINITE SURGE FORWARD BEFORE THE CAR STOPS. IT HAS HAPPENED ON DIFFERENT ROAD SURFACES, SMOOTH, UNEVEN & BUMPY WHEN BOTH WET & DRY. THEY DID NOT FIND ANY SOLUTION TO THIS PROBLEM & TOLD ME TO CONTINUE TO MONITOR IT. THEY ALSO ADVISED THAT NO RECALL HAS BEEN ISSUED OR OTHER COMPLAINTS RECEIVED. *TR

A COUPLE OF TIMES WHEN I HAVE APPLIED PRESSURE TO THE BRAKES ON MY 2010 PRIUS, THE CAR HAS ACCELERATED MOMENTARILY INSTEAD OF BRAKING. *TR

THIS HAS HAPPENED APPROXIMATELY TEN TIMES SINCE WE BOUGHT OUR 2010 PRIUS IN AUGUST. I APPLY THE BRAKES, THE CAR STARTS TO SLOW DOWN, AND THEN ACCELERATES BRIEFLY. I THOUGHT THAT IT WAS JUST THAT THE BRAKES LET UP FOR A MOMENT, BUT THE LAST COUPLE OF TIMES IT HAS HAPPENED I REALIZED THAT IT'S MORE LIKE THE CAR ACTUALLY ACCELERATES FOR A MOMENT. IT HAS HAPPENED SEVERAL TIMES WHEN I'M GETTING OFF THE HIGHWAY, ON THE EXIT RAMP, SO I'M GOING FOR A RELATIVELY FAST SPEED TO SLOWING DOWN. BUT IT HAPPENS OTHER TIMES, TOO--FOR INSTANCE, WHEN I'M DRIVING IN THE CITY AND STOPPING FOR A RED LIGHT. TONIGHT IT HAPPENED AND I WOULD SAY THAT THE CAR MOVED FORWARD QUICKLY FOR ABOUT 15 FEET. I HAVE HAD THE CAR CHECKED BY TOYOTA WHO HAS FOUND NOTHING WRONG WITH MY BRAKES, BUT I KNOW THAT THIS IS A POTENTIALLY DANGEROUS GLITCH. *TR

WHILE APPLYING THE BRAKES TO SLOW DOWN OR TO COME TO A STOP, IF THE CAR HITS A BUMP, POTHOLE OR THE LIKE, THE BRAKES RELEASE MOMENTARILY, CAUSING THE CAR?S MOMENTUM TO CONTINUE FORWARD LONGER/FURTHER THAN YOU WOULD NORMALLY EXPECT OR WANT. THIS IS ESPECIALLY DANGEROUS WHEN COMING TO A STOP AT A NEW YORK CITY PEDESTRIAN CROSSWALK OR TRYING TO SLOW DOWN WITH A CAR CLOSE IN FRONT OF YOU. I BROUGHT THE CAR INTO THE DEALERSHIP AND HAD IT EVALUATED BY TOYOTA'S FIELD TECHNICAL SPECIALIST WHO REPORTED THE FOLLOWING, ""WHEN [THE CAR] SENSES IMPENDING WHEEL SLIP, IT WILL FIRST DISABLE THE REGENERATIVE BRAKES. WHEN IT DOES THAT IT FEELS LIKE THE CAR SORT OF ACCELERATES BECAUSE YOU LOST THE REGENERATIVE BRAKING AND YOU'RE USING THE BRAKE ASSIST THAT YOU HAVE FROM YOUR FOOT. SO THAT IS 'NORMAL OPERATION' ON THE SYSTEM. IT IS WORKING AS DESIGNED." DESPITE THE EXPLANATIONS FOR WHY THIS IS HAPPENING AND WHETHER OR NOT THIS IS ?NORMAL OPERATION?, THE BOTTOM LINE IS, IF THE CAR IS NOT STOPPING WHEN IT SHOULD, THE SAFETY OF PASSENGERS AND PEDESTRIANS IS IN JEOPARDY. I CALLED AND WROTE TWO CERTIFIED LETTERS TO TOYOTA'S CUSTOMER EXPERIENCE DEPARTMENT AND TO AKIO TOYOTA, AND RECEIVED A PHONE CALL FROM AN EXECUTIVE ANALYST FROM THE PRESIDENT'S OFFICE. NO TOYOTA REPRESENTATIVE WOULD DO ANYTHING IN REGARDS TO THE PROBLEM--THEY MAINTAIN THAT THE BRAKING OPERATION IS NORMAL. I HAVE SEEN OTHER COMPLAINTS ON THE NHTSA WEB SITE AND ON PRIUS OWNERS BLOGS THAT CONTRADICT TOYOTA'S ASSERTION AND SUPPORT THE CLAIM THAT THE BRAKES ARE INDEED A SAFETY ISSUE THAT MUST BE ADDRESSED.*TR
