2010 Toyota Prius Complaint Log

SUDDEN INCREASE IN SPEED DURING BRAKING OVER UNEVEN SURFACE, POTHOLES, SNOW, RAIL ROAD TRACKS. *TR

2010 TOYOTA PRIUS. BRAKES WOULD NOT WORK AT LOW SPEED WHEN APPROACHING AN INTERSECTION COVERED WITH SAND/ GRAVEL FROM RECENT SNOW ABATEMENT WORK. CAR ROLLED THROUGH STOP SIGN. *TR

OVER THE PAST 2-3 WEEKS WE HAVE HAD UNPREDICTABLE OCCURRENCES OF THE BRAKES OF OUR 2010 PRIUS GRABBING/LOCKING WHEN ONLY GENTLE/GRADUAL PRESSURE HAS BEEN APPLIED TO THE BRAKE PEDAL. THE SUDDEN FULL-BRAKING OF THE VEHICLE CAUSES IT TO LURCH AND, IF DRIVERS DO NOT TAKE OFF THE BRAKE COMPLETELY, TO STOP SHORT. *TR

SOMETIMES WHEN OUR 2010 PRIUS HITS A POTHOLE, ICE CHUNK OR OTHER BUMPY ROAD CONDITIONS WE WILL VERY TEMPORARILY LOSE BRAKING POWER. IT SEEMS TO OCCUR AS THE TRACTION CONTROL OR ANTI-LOCK KICKS IN. THIS HAS NOT BEEN A ONE TIME INCIDENT, BUT ALSO DOES NOT OCCUR EVERY TIME. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED AS HE WAS STOPPING HIS VEHICLE, HE HIT A BUMP IN THE ROAD WHILE DEPRESSING THE BRAKE THE VEHICLE LURCHED FORWARD AND ACCELERATED. THE VEHICLE WAS TAKEN TO THE DEALER AND CONTACT WAS TOLD THIS WAS NORMAL AND IT IS THE ELECTRICAL ENGINE SWITCHING TO THE GAS ENGINE. THE CONTACT STATED THAT THIS IS A CONTINUOUS PROBLEM WHILE STOPPING THE VEHICLE. THE FAILURE MILEAGE WAS 8,800.

SINCE BUYING A 2010 PRIUS IN JUNE, I HAVE EXPERIENCED THREE "SURGING" EVENTS WHILE BRAKING AS I DECENDED HILLS. TWO INVOLVED SITUATIONS INVOLVING HITTING ROAD DEPRESSIONS, WHICH ALMOST CAUSED ME TO GO THROUGH TRAFFIC LIGHTS, ONE INVOLVED A ROAD COVERED WITH 1-2 INCHES OF SNOW, WHICH ALMOST PROPELLED ME INTO ONCOMING TRAFFIC AT A STOP SIGN. ALL SITUATIONS OCCURRED AS I WAS DESCENDING HILLS AND SLOWING SPEED BY BRAKING. THE FIRST INCIDENT OCCURRED IN THE SUMMER, THE LAST YESTERDAY. I REPORTED THIS TO MY DEALER, WHO HAD NO INFORMATION ON IT FROM TOYOTA, BUT ADVISED ME TO FILE A COMPLAINT WITH TOYOTA, WHICH I DID, CASE #1002106542. *TR

I OWN A 2010 TOYOTA PRIUS..PURCHASED IN AUGUST 2009...CURRENTLY GOING FOR 15K MILES ON THE ODOMETER. I WANT TO REPORT ISSUES WITH SUDDEN ACCELERATION EVEN WHEN I AM STEPPING ON THE BRAKE. I NOTICED EVERY TIME I PASS THRU UNEVEN ROAD, FOR EXAMPLE POTHOLES, ICY ROADS, SNOW. THE MOST COMMON ISSUE I HAVE IS AS I AM GOING DOWN THE ROAD AND CAR HITS A POTHOLE OR MANHOLE (THOSE WITH METAL COVERS) THE CAR WILL SUDDENLY ACCELERATE, ALTHOUGH I AM STEPPING ON THE BRAKE. SOMETIMES I AM AFRAID I WILL HIT THE CAR IN FRONT OF ME, ESPECIALLY WHEN IM IN TRAFFIC. EVEN GOING AT 5-15 MPH, THE CAR WILL ACCELERATE WHEN IT HITS UNEVEN ROAD LIKE POT HOLES OR ICY ROADS. THIS HAS HAPPEN QUITE A FEW TIMES SINCE I PURCHASED THE VEHICLE. JUST YESTERDAY, WE HAD ABOUT 1-2 INCHES OF SNOW. I WAS DRIVING SLOW AND WHEN MAKING A LEFT TURN, THE CAR HIT SOME UNEVEN ROAD AND SNOW AND ACCELERATED WHEN I WAS STEPPING ON THE BRAKE TO MAKE THE TURN. THE CAR WENT UP THE SIDEWALK AND THE BUMPER CRACKED AS IT HIT THE CONCRETE EDGE THAT SEPARATES THE ROAD AND THE SIDEWALK. NO ONE WAS HURT AND NO PROPERTY DAMAGE WAS DONE. THE CAR IS WORKING FINE, BUT THIS SUDDEN ACCELERATION ISSUE IS A MAJOR CONCERN, ESPECIALLY NOW THAT I READ AND HEAR IN THE NEWS THAT 2010 TOYOTA PRIUS ARE BEING REPORTED WITH COMPLAINTS OF SUDDEN ACCELERATION. I THOUGHT MY ISSUE WAS AN ISOLATED CASE. PLEASE TAKE THIS COMPLAINT INTO ACCOUNT. I WILL BE GOING TO THE DEALERSHIP THIS WEEKEND FOR THE 15K SCHEDULED MAINTENANCE AND WILL REPORT THE ISSUE TO THEM. *TR

IN CITY DRIVING CONDITIONS, THE BRAKE PEDAL OF MY 2010 TOYOTA PRIUS FAILS TO RESPOND WHEN IT IS DEPRESSED AND THE CAR HITS A BUMP. THE VEHICLE FEELS AS IF IT MOMENTARILY LURCHES FORWARD BEFORE IT BEGINS TO SLOW. THIS IS AN INTERMITTENT PROBLEM THAT OCCURS WHEN THE VEHICLE HITS AN OBSTRUCTION, SUCH AS A POT HOLE, WHILE THE BRAKE PEDAL IS BEING PRESSED. THE MOST RECENT OCCURRENCE IS DETAILED BELOW. *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

THE BRAKES ON MY PRIUS HAVE FAILED THREE TIMES IN THREE WEEKS IN BOTH CITY AND RURAL DRIVING CONDITIONS--TWO TIMES I WAS BRAKING WHILE DRIVING DOWN A HILL (BOTH UNDER 30 MPH) AND ONCE WHILE DRIVING ON A SECONDARY BLACKTOP ROAD (35 MPH). *TR 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'S A NAUSEATING FEELING WHEN THIS HAPPENS. I WAS PLANNING ON TAKING THE PRIUS ON A CROSS-COUNTRY TRIP IN THE SPRING BUT WILL NOT NOW BECAUSE OF THIS BRAKING ISSUE. IT IS NOT A SAFE VEHICLE. I HAVE GREAT CONCERN FOR MY SAFETY AND THE SAFETY OF OTHERS, PARTICULARLY PEDESTRIAN SAFETY AT INTERSECTIONS. I AM ALSO GOING TO POST MY COMPLAINT ON PRIUSCHAT.COM (ONLINE PRIUSPHILE COMMUNITY OF WHICH I AM A MEMBER) IN HOPES THAT OTHERS WILL COME FORWARD WITH THEIR BRAKING PROBLEMS TO NHTSA, FORCING TOYOTA TO FIX THIS PROBLEM. I COMPLETED A COMPLAINT FORM FOR LAST WEEK ON YOUR SITE (DIDN'T REQUIRE VIN NUMBER) BUT SINCE BRAKE FAILURE OCCURRED AGAIN TODAY, I REALIZE THAT THIS IS NOT AN ISOLATED INCIDENT. THEREFORE, I AM FILING THIS FORMAL NHTSA COMPLAINT. *TR

THIS IS TO REPORT THAT MY PRIUS 2010 CAR HAS EXPERIENCED THE DELAYED BRAKE PROBLEM. I FIND THIS HAPPENS WHEN I AM DRIVING OVER A CERTAIN ROAD THAT HAS SOME SMALL BUMPS. I AM GOING AROUND 20 OR LESS STOPPING FOR A STOP LIGHT AND I GET A VERY SLIGHT DELAY IN BRAKING, LESS THAN 1 SECOND I THINK. I HAVE NEVER HAD ANY TROUBLE STOPPING IN THE REQUIRED DISTANCE BEFORE THE STOP LIGHT, IT JUST GETS YOUR ATTENTION AND NEEDS CORRECTING BY TOYOTA. *TR

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

I WAS STOPPED AT A TRAFFIC LIGHT. THE STREET WAS UPHILL. MY 2010 PRIUS BEGAN TO ROLL BACK, ALTHOUGH I WAS STEPPING ON THE BRAKE. THIS CONTINUED FOR SEVERAL SECONDS, WHILE I TRIED TO PRESS HARD ON THE BRAKES (THEY WERE NOT RESPONSIVE). LUCKILY, THERE WAS NO CAR BEHIND ME, OTHERWISE, A CRASH WOULD HAVE ENSUED. ROAD CONDITIONS WERE WET AND SOMEWHAT SLIPPERY AT THAT TIME. THIS WAS MY FIRST EXPERIENCE WITH THIS BRAKE FAILURE, WHICH LASTED FOR A FEW SECONDS. I HAVE NOT HAD A CHANCE TO CONTACT THE DEALER YET. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING IN REVERSE OUT OF THE GARAGE HE EXPERIENCED AN UNINTENDED ACCELERATION AT LEAST THREE TIMES WITHIN A MONTH. ALSO WHEN HE WAS DRIVING AT 5 MPH AND COMING TO A STOP, THE VEHICLE LUNGED FORWARD AND AS HE JAMMED HIS FOOT HARDER ON THE BRAKES, THE VEHICLE KEPT GOING . THE VEHICLE WAS TAKEN TO THE DEALER ON TWO OCCASIONS; HOWEVER, DURING A TEST DRIVE THEY WERE UNABLE TO DUPLICATE, DIAGNOSE OR REPAIR THE FAILURE. THE TOYOTA MANUFACTURER HAS NOT BEEN CALLED. THE FAILURE MILEAGE WAS 1,700.

I'M AN OWNER OF A 2010 PRIUS. TEN DAYS OR SO AFTER I PURCHASED THE CAR(IN JAN 2010), I EXPERIENCED A LOSS IN BRAKING WHICH RESULTED IN DAMAGE TO THE BUMPER. NUMEROUS!!!! ALMOST DAILY!!!! TIMES SINCE, EVEN AFTER THE RECALL FIX (DONE ON MY VEHICLE ON 3/10/10), I HAVE EXPERIENCED, NOT ONLY A LOSS OF BRAKING (USUALLY WHILE GOING OVER SOME LITTLE BUMP) BUT THE CAR ACTUALLY LURCHING FORWARD. QUITE DRAMATIC AND SCARY, ESPECIALLY IF THERE IS A STOP SIGN, INTERSECTION, A CAR OR A PERSON IN FRONT OF YOU. LAST THURS (11/10/11), THE ROAD SURFACE WAS WET, AND I BRAKED AND HAD NO, NONE , NADA BRAKES AND I REAR ENDED THE PERSON IN FRONT OF ME. I PAID FOR HER DAMAGE OUT OF MY OWN POCKET. I HAVE NOT FIXED THE DAMAGE DONE TO MY CAR. BRAND NEW ALL SEASON TIRES ON THE CAR, BY THE WAY. TODAY (11/14/11), AGAIN THE ROAD SURFACE WAS WET, I WAS BEHIND A CAR IN THE RIGHT LANE WHEN A CAR INAPPROPRIATELY BEGAN MERGING FROM A RAMP ON THE RIGHT, CAUSING THE CAR IN FRONT OF ME TO SUDDENLY SLOW DOWN. I BRAKED, AND AGAIN, NOTHING!!! I QUICKLY LOOKED IN MY SIDE VIEW MIRROR AND SAW I HAD CLEARANCE TO GO IN THE LEFT LANE, AND MANAGED TO AVOID CONTACT. 10 DAYS AFTER I PURCHASED THE 2010 PRIUS, I SAID I WANTED TO RETURN IT AND I SENT IN ALL THIS DOCUMENTATION CERTIFIED MAIL, BUT TOYOTA REJECTED EVERYTHING. THERE IS A DEFECT IN THIS CAR AND IT IS UNSAFE. *TR

WHEN BRAKING AT LOW SPEEDS, VEHICLE ACCELERATES FOR A SECOND BEFORE BRAKING. THIS OCCURS WHEN HITTING A BUMP. I EXPERIENCE THIS ALMOST EVERY DAY ON MY WAY TO WORK AT THE SAME LOCATION. THE ROAD IS SLOPED SLIGHTLY DOWNHILL IN A RESIDENTIAL STREET. I HAVE NOT CONTACTED TOYOTA YET. *TR

WE LIVE IN CHICAGO AND OWN A 2010 PRIUS. WE ALSO HAVE EXPERIENCED THE ACCELERATION (FORWARD SURGE) UPON BRAKING ON UNEVEN TERRAIN REPORTED BY OTHER OWNERS. NO ACCIDENT, BUT IT HAPPENS OFTEN ON OUR CITY STREETS AND IT IS A LITTLE UNNERVING. THE LAST TIME IT HAPPENED WAS YESTERDAY. *TR

I OWN A 2010 TOYOTA PRIUS AND HAVE ENCOUNTERED THE SAME ISSUES WITH THE BRAKES THAT MANY OTHERS HAVE REPORTED. WHEN BRAKING (WHICH I DO OVER A LONGER THAN USUAL DISTANCE AND TIMEFRAME BECAUSE OF THE CAR'S ABILITY TO REGENERATE POWER WHILE BRAKING), THE BRAKE PEDAL DROPS AND THE CAR SUDDENLY ACCELERATES WHENEVER THE VEHICLE HITS A BUMP OR POTHOLE. THIS HAS HAPPENED MULTIPLE TIMES SINCE I TOOK POSSESSION OF THE VEHICLE IN JUNE 2009. NO ACCIDENTS OR INJURIES HAVE RESULTED, BUT I MUST BE PARTICULARLY CAUTIOUS OF ROAD CONDITIONS WHEN BRAKING BECAUSE THIS HAPPENS FREQUENTLY AND I AM CONCERNED ABOUT THE POSSIBILITY OF FUTURE ACCIDENTS OR PEDESTRIAN INCIDENTS. *TR

WHEN BRAKING AND GOING OVER ROUGH ROAD OR POTHOLES, THE CAR FEELS LIKE IT IS ACCELERATING. IT IS NECESSARY TO EXERT ADDITIONAL PRESSURE ON THE BRAKE PEDAL, BUT SOMETIMES DOES NOT FEEL LIKE THIS IS HELPING. *TR

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

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

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

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

1. I AM DRIVING ON A REGULAR ROAD. 2. WHEN I AM BRAKING AND MY CAR HITS A BUMP IT SEEMS TO JOLT FORWARD BRIEFLY AND I NEED TO HIT THE BRAKES HARDER TO STOP. *TR

BRAKES ON PRIUS 2010 PERIODICALLY HAVE A "LAG" OR DELAY TIME BEFORE THEY ENGAGE. I APPLY THE BRAKES, AND NO GRABBING OR SLOWING DOWN OCCURS FOR 2-3 SECONDS. THIS BEGAN TO HAPPEN DURING JANUARY (CAR PURCHASED IN NOVEMBER). I HAVE 7000 MILES ON THE CAR. 1ST TIME- WENT OVER ROUGH PART OF ROAD AND APPLIED BRAKES, DELAYED TIME UNTIL BRAKES ACTED. FELT AS IF I WAS FLOATING- LOSS OF TRACTION FEELING. BROUGHT CAR INTO TOYOTA WESTPORT CT DEALER ON JAN 14, 2010 AND WAS TOLD NO PROBLEM FOUND. IT HAS CONTINUED TO OCCUR: 2ND TIME - COLD MORNING AND 3X NO BRAKING TRACTION AS DRIVING ABOUT 10-20 MPH AND TRYING TO SLOW DOWN FOR A STOP SIGN AND WHEN A CAR ENTERED FROM A SIDE STREET 3RD TIME (FEB 2, 2010) - ON HIGHWAY AROUND 2 PM. CRUISE CONTROL WAS ON AND APPLIED BRAKES - NO SLOWING DOWN FOR ABOUT 3 SECONDS. VERY SCARY FEELING AS IT HAPPENS. *TR

I AM ALSO AN OWNER OF A 2010 PRIUS. I HAVE DRIVEN THIS CAR SINCE AUGUST 2010. WHEN YOU GO OVER A BUMP WHEN BRAKING THERE IS A SUDDEN BURST OF ACCELERATION. IT ABSOLUTELY HAPPENS AND IS REPRODUCIBLE. I GO OVER THE SAME BUMP EVERY DAY ON MY COMMUTE HOME, AND THIS HAPPENS REPEATEDLY. IT HAS NEVER CAUSED AN ACCIDENT, BUT IT IS A DEFECT AND IS DISCONCERTING. GIVEN THE OTHER ACCELERATION PROBLEMS TOYOTAS HAVE EXPERIENCED, THIS NEEDS TO BE INVESTIGATED. *TR

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

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

TOYOTA PRIUS 2010 FAILED TO STOP AT STOP SIGN. I GOT A BRAND NEW TOYOTA PRIUS 2010 IN LATE OCTOBER 2009. MOST OF THE TIME THE BRAKES HAVE BEEN VERY GOOD HOWEVER I NOTICED SEVERAL TIMES THAT WHEN I PRESS THE BRAKES THE CAR KEPT GOING FOR A GOOD FEW SECONDS BEFORE IT STOPS. YESTERDAY I WAS IN A SMALL LOCAL ROAD WITH SPEED AROUND 28 MILE/HR. WHEN APPROCHING THE INTERSECTION, I PRESSED THE BRAKE BUT THE CAR WAS NOT SLOW DOWN, I KEPT PRESSING THE BRAKE VERY HARD AND IT FINALLY STOPPED BUT THE CAR WAS INTO THE INTERSECTION ALREADY. THANK GOD, THERE WAS NOBODY CROSSING THE STREET. I GOOGLED PRIUS 2010 BRAKE PROBLEM AND FOUND THERE WERE MANY SAME COMPLAINTS OUT THERE AND SINCE DEALERS COULD NOT REPRODUCE THE DEFECT, THEY CAN NOT OFFER A FIX. *TR

I HAVE A 2010 PRIUS, I HAVE ALSO NOTICED LOSS OF BRAKES. WHEN COMING TO A STOP OR GOING AROUND A CORNER AND HITTING A POT HOLE THE BRAKES SEEM TO SLIP. I CALLED THE DEALER TODAY IN KANSAS CITY THEY TOLD ME THEY HAD NO RECALLS ON THE BRAKES FOR THE 2010 PRIUS. CAN ANYTHING BE DONE? ON GOING PROBLEM! MY DEALER IS MOLLE TOYOTA. *JB

I OWN A 2010 TOYOTA PRIUS WHICH WAS PURCHASED IN SEPTEMBER 2009. MY BRAKES FAIL TO IMMEDIATELY STOP MY CAR WHEN APPLIED GOING OVER BUMPY SECTIONS IN THE ROAD, HITTING A POTHOLE, OR WHEN ON SLIPPERY SECTIONS OF THE ROAD. WHEN HITTING A BUMP IT ACTUALLY FEELS LIKE THE CAR LURCHES FORWARD. THE CAR WILL EVENTUALLY STOP AFTER PUSHING THE BRAKE TO THE FLOOR WITH FORCE. IT IS VERY DISCONCERTING AND THE POTENTIAL FOR HITTING THE CAR IN FRONT OF YOU OR A PERSON IS VERY HIGH. *JB

I WAS BRAKING MY 2010 PRIUS III WHEN I WENT OVER SOME RAILROAD TRACKS. THE VEHICLE SUDDENLY ACCELERATED AND I HAD TO STEP OFF THE BRAKE PEDAL AND RE-APPLY THE BRAKES TO GET THE VEHICLE TO BEGIN BRAKING AGAIN. THE ACCELERATION LASTED FOR MORE THAN 1 SECOND AND THE VEHICLE DIDN'T START BRAKING AGAIN, UNTIL I HAD REAPPLIED THE BRAKES. *JB

THE BRAKES IN MY 2010 TOYOTA PRIUS DO NOT OPERATE PROPERLY. I HAVE HAD THE CAR 3 MONTHS WITH 1847 MILES. OVER THIS TIME I MUST INCREASINGLY PRESS THE BRAKE PEDAL CLOSER TO THE FLOOR TO STOP THE CAR. TODAY IN DRY WEATHER, I NEARLY HIT THE CAR ALMOST 50 YARDS IN FRONT OF ME WHEN IT STOPPED AND ALTHOUGH I PRESSED THE PEDAL FIRMLY IT TOOK A VERY LONG TIME FOR THE BRAKES TO GRAB. *JB

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

IN SNOWY WEATHER I TRIED TO STOP ON SLIPPERY PAYMENT AT SLOW SPEEDS AT A FOUR WAY STOP. THE BRAKES LET GO FOR A FEW SECONDS BEFORE RECONNECTING. THIS HAS HAPPENED SEVERAL TIMES BEFORE ON BUMPY OR SLIPPERY PAVEMENT. IT NEVER LASTS FOR LONG, BUT IT DOES INCREASE STOPPING DISTANCE. *TR

I BOUGHT A TOYOTA PRIUS V 2010. I HAVE COMPLAINED TO TOYOTA ABOUT THE BRAKING SYSTEM. I AM ALSO FILLING A FORMAL COMPLAINT WITH NHTSA. ALSO THE BACK AUTO DIMMING MIRROR DOESNT WORK PROPERLY. THEY CANT FIND A FIX. LANE KEEP ASSIST WORKS REALLY POORLY. I WOULD SAY I DOESNT WORK! ALSO BLUETOOTH SYSTEMS DOESNT WORK PROPERLY. THERE IS A DELAY IN ANSWERING THE CALL. *TR

I AM THE OWNER OF A 2010 TOYOTA PRIUS PURCHASED NEW ON JANUARY 21, 2010. CAR HAS ABOUT 400 MILES ON THE ODOMETER. ON FEBRUARY 2, 2010 WHILE ATTEMPTING TO STOP AT A STOP SIGN, TRAVELING AT A SLOW RATE OF THE SPEED, THE BRAKES FAILED TO STOP THE CAR. AFTER SEVERAL ATTEMPTS TO APPLY THE BRAKES, THEY FINALLY STOPPED THE CAR NARROWLY MISSING CROSS TRAFFIC. THE PAVEMENT WAS SMOOTH AND SPEED WAS LESS THAN 25MPH. *TR

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

I WAS DRIVING MY 2010 TOYOTA PRIUS USING CRUISE CONTROL ON A HIGHWAY. I DISENGAGED CRUISE CONTROL TO SLOW DOWN AS A VEHICLE ENTERED THE HIGHWAY IN FRONT OF ME. ONCE THE SECOND VEHICLE HAD ACCELERATED AHEAD, I RE-ENGAGED CRUISE CONTROL AT MY DESIRED SPEED. THE CRUISE CONTROL ENGAGED, BUT CONTINUED ACCELERATION, AS IF I WAS ACTIVATING THE CRUISE CONTROL MECHANISM'S ACCELERATE "PADDLE", WHICH I WAS NOT ACTUALLY DOING. I IMMEDIATELY DIS-ENGAGED CRUISE CONTROL, SLOWED TO MY DESIRED SPEED, AND RE-ENGAGED CRUISE CONTROL. AT THIS POINT, THE CRUISE CONTROL RESUMED PROPER OPERATION AND I WAS ABLE TO DRIVE AT MY SELECTED SPEED. *TR

PRIUS 2010 "SKIDDED" AT SLOW SPEED ON COLD ROADWAY TWICE. JUST PURCHASED THE CAR IN OCTOBER. *TR

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". I ONLY YESTERDAY LEARNED OF THIS AVENUE OF COMPLAINT OR I WOULD HAVE NOTIFIED YOU OF THIS PROBLEM EARLIER. THANK YOU FOR YOUR CONSIDERATION AND EFFORTS TO HOLD TOYOTA ACCOUNTABLE FOR THIS ISSUE. SO FAR I HAVE HAD ABSOLUTELY NO SUCCESS. *TR

I OWN A 2010 PRIUS SINCE AUGUST 2009. IN THE PAST MONTH OR SO, I NOTICED THAT WHEN I MADE A SLOW RIGHT TURN OR STOP ON A DRAINAGE GRILL, I SUDDENLY LOST BRAKE POWER. THE CAR LUNGES FORWARD FOR A FOOT OR TWO BEFORE IT STOPS UPON HARD STEPPING ON THE BRAKE PEDAL. I HAD A NEAR ACCIDENT ON FEB 2, 2010 AS I STOPPED AT A RED LIGHT UNDER A BRIDGE. THIS ANOMALY HAPPENS PRIMARILY AROUND CORNERS AND BUMPY ROADS. THE PROBLEM DID NOT HAPPEN AT THE BEGINNING SO I SUSPECT THAT WITH TIME, THE PROBLEM WILL GET PROGRESSIVELY WORSE. *TR

BRAKE WAS NOT WORKING WHEN APPLIED TRYING TO SLOW DOWN ON A SNOW COVERED FROZEN ROAD AT ABOUT 25MPH. IT'S NOT FOR A STOP OR SUDDEN BRAKING. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES WERE ULTRA-SENSITIVE AND WHEN SHE LIGHTLY DEPRESSED THE PEDAL, THE VEHICLE WOULD JERK AS IF SHE MADE AN ABRUPT STOP. OTHER TIMES, SHE HAD TO PUSH THE BRAKE PEDAL EXTREMELY HARD TO STOP THE VEHICLE. SHE CALLED THE DEALERSHIP AND WAS TOLD THAT IT WAS NOT A PROBLEM. SHE HAD NOT CONTACTED THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS 1,218. THE FAILURE MILEAGE WAS APPROXIMATELY 1,200.

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. THE DATE BELOW ONLY REPRESENTS THE MOST RECENT OF MULTIPLE TIMES WE EXPERIENCED THIS PROBLEM. *TR

I HAVE A 2010 PRIUS IV AND CAN CERTAINLY SAY THAT I HAVE FELT SEVERAL TIMES A BIT OF "BRAKE-LOSS" ON THIS VEHICLE. BY THAT, I MEAN THAT AT TIMES I HAVE TO PUSH DOWN MUCH HARDER ON THE BRAKE PEDAL TO COME TO A STOP. THIS HAPPENS AT RANDOM TIMES AND CAUSES ME A BIT OF NERVOUSNESS AS A FEW TIMES I CAME CLOSE TO HITTING THE CAR IN FRONT OF ME. THIS TENDS TO HAPPEN AS I AM COMING TO A STOP, NOT DURING HIGH-SPEED BRAKING. I WOULD ESTIMATE THAT THIS HAS HAPPENED AT LEAST 10 TIMES DURING 4,000 MILES OF DRIVING. *TR

I PURCHASED A NEW 3RD GENERATION TOYOTA PRIUS IN AUGUST OF 2009. I HAVE NOTICED TWO INCIDENTS WHERE MY BRAKES DID NOT RESPOND PROPERLY IMMEDIATELY AFTER PASSING OVER DISTINCT POTHOLES. THEY HAD WAY TOO MUCH "GIVE." ON THE SECOND PUMP OF THE BRAKES, THE FULL BRAKING POWER APPEARED TO BE RESTORED. *TR

I HAVE A 2010 TOYOTA PRIUS AND HAVE EXPERIENCED THE SAME ISSUE RECENTLY BEING REPORTED. WHILE BRAKING, WHEN GOING OVER A POTHOLE, BUMP OR WET SURFACE, THE CAR APPEARS TO LUNGE FORWARD FOR A SECOND. THIS HAS RECURRED AT LEAST 10 TIMES SINCE I PURCHASED THE CAR IN AUGUST, 2009. *TR

MY PRIUS IS HAVING BRAKE ISSUES. WHEN I TOOK IT BACK TO THE DEALER THE SERVICE REP RODE IN THE CAR WITH ME AND SINCE IT DIDN'T SLIP DURING OUR 2 BLOCK DRIVE HE SAID HE CAN'T AUTHORIZE A REPAIR SINCE ITS NOT PART OF THE RECALL. I WANT TO JUST RETURN THIS THING BEFORE I GET IN AN ACCIDENT BUT THEY TOLD ME I WILL LOSE 100 POINTS ON MY CREDIT SCORE. WHAT CAN I DO?! *TR

I WAS DRIVING MY 2010 TOYOTA PRIUS OVER A ROUGH SPOT IN THE ROAD. WHEN I TRIED TO SLOW THE CAR BY APPLYING MY BRAKES, THEY DID NOT RESPOND. IN FACT, INSTEAD OF SLOWING DOWN, MY CAR ACCELERATED ABRUPTLY, SHOOTING AHEAD SEVERAL FEET BEFORE I WAS ABLE TO REGAIN CONTROL OF THE VEHICLE. THIS EPISODE LASTED ONLY A FEW SECONDS, AND THEN THE BREAKING FUNCTION RETURNED. SINCE I WAS TRAVELING AROUND TWENTY MILES PER HOUR AT THE TIME AND NO ONE WAS DIRECTLY IN FRONT OF ME, THE EPISODE DID NOT RESULT IN ANY ACCIDENT OR INJURY. WHILE I HAVE HAD ONLY ONE OCCURRENCE OF THIS BRAKE FAILURE/ACCELERATION SINCE OWNING MY CAR, PURCHASED AT THE END OF SEPTEMBER, 2009, THE FACT THAT THIS CAR HAS A HISTORY OF PERFORMING IN THIS UNCONTROLLED WAY HAS ME DEEPLY CONCERNED ABOUT DRIVING IT. *TR
