2010 Toyota Prius complaints

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING 10 MPH AND ENGAGING THE BRAKE PEDAL, THE VEHICLE BRIEFLY ACCELERATED ON ITS OWN AND THE BRAKES MALFUNCTIONED. THE FAILURE HAS OCCURRED 10 TIMES SINCE THE VEHICLE WAS PURCHASED. THE DEALER WAS CONTACTED AND THEY STATED THAT WAS A SAFETY FEATURE. NO REPAIRS WERE MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 500 AND THE CURRENT MILEAGE WAS 4826.

I HAVE A 2010 PRIUS I PURCHASED IN OCTOBER OF 2009. TWO DIFFERENT TIMES I WAS DRIVING ON ICE AND WAS SLIDING WHILE APPLYING THE BRAKES. WHILE BRAKING THE BRAKES COMPLETELY STOPPED WORKING FOR A SECOND OR TWO, THEN BEGAN WORKING AGAIN. THE SECOND TIME IT HAPPENED I ALMOST CRASHED INTO CARS AT AN INTERSECTION BECAUSE I COULD NOT STOP AT THE INTERSECTION. BOTH TIMES THIS HAPPENED I WAS GOING AT A VERY SLOW RATE OF SPEED BECAUSE OF THE ROAD CONDITIONS. MY HUSBAND HAD THOUGHT I WAS JUST CRAZY OR NOT UNDERSTANDING ABS BUT THIS IS NOT THE FEELING OF ABS. I COULD FEEL THE ABS BRAKES AND THEN A MOMENT OF NOTHING, THEN BRAKES AGAIN. *TR

I HAVE A 2010 TOYOTA PRIUS. WHEN I AM BRAKING AND I HAPPEN TO HIT A BUMP IN THE ROAD, MY CAR LURCHES FORWARD WHILE MY FOOT IS ON THE BRAKE. I HAVE NOT HAD AN ACCIDENT, BUT IT HAS BEEN CLOSE A COUPLE OF TIME. THIS BEGAN HAPPENING ALMOST IMMEDIATELY AFTER I BOUGHT THE CAR. I BOUGHT IT IN JULY 2009. INCIDENTS OCCURRED BETWEEN AUGUST 2009 AND CONTINUE THROUGH THE PRESENT. P.S. I DON'T KNOW WHAT TYPE OF BRAKES THEY ARE: AIR, HYDRAULIC OR ELECTRIC - I JUST PICKED ONE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHEN THE CONTACT ATTEMPTED TO APPLY THE BRAKES WHILE DRIVING ON A SLIPPERY SURFACE THE BRAKES DID NOT FULLY ENGAGE WHICH INCREASED THE STOPPING DISTANCE. THE DEALER WAS UNABLE TO REPRODUCE THE FAILURE. THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 5000. UPDATED 03/09/10. *LJ UPDATED 05/13/10

MY 2010 TOYOTA PRIUS LURCHES WHEN GOING OVER A ROUGH PATCH OF ROAD WHILE I'M USING THE BRAKES. THERE IS A PARTICULAR PATCH OF ROAD NEAR MY HOME WHERE THIS HAS HAPPENED REPEATEDLY. *TR

WHENEVER I HIT A BUMP WHILE APPLYING BRAKES ON MY 2010 TOYOTA PRIUS, THE BRAKES STOP WORKING FOR A SHORT INTERVAL (ABOUT A SECOND). I FIRST NOTICED THIS ISSUE ABOUT TWO MONTHS AGO WHILE DRIVING TO A DOCTOR APPOINTMENT. THERE WAS A SMALL, UNAVOIDABLE POTHOLE ABOUT 200 FEET BEFORE A TRAFFIC LIGHT. THE LIGHT HAD TURNED RED, AND I WAS BRAKING AS I HIT THE POTHOLE. TO MY SURPRISE, MY PRIUS LURCHED FORWARDED NEARLY HITTING THE CAR IN FRONT OF ME. FORTUNATELY, THE BRAKES RE-ENGAGED AS I ATTEMPTED TO BRAKE HARDER. I HAVE HAD TO TRAVEL THAT SAME ROAD 3X A WEEK FOR THE PAST TWO MONTHS, AND THE PROBLEM IS CONSISTENT AND OCCURS EVERY TIME I HIT THAT BUMP WHEN BRAKING. I HAVE SINCE NOTICED IT AT OTHER TIMES, ALWAYS WHEN I HIT A BUMP AND AM BRAKING. THE BRAKING LAG IS SUBSTANTIAL ENOUGH TO HAVE ALMOST CAUSED ME TO GET IN AN ACCIDENT ON SEVERAL OCCASIONS. THE BUMPS THAT HAVE TRIGGERED IT HAVE NOT BEEN ANYTHING OUTSIDE OF WHAT IS VERY COMMON TO DRIVING. I HAVE CALLED THE DEALERSHIP, AND THEY ACKNOWLEDGE THAT THERE IS NO REPAIR OFFERED AT THIS TIME (BUT CLAIM THAT THEY EXPECT ONE IN A FEW WEEKS). THEY HAVE OFFERED ME A RENTAL CAR FOR A FEW WEEKS. *TR

MOMENTARY LOSS OF BRAKING WHEN PASSING OVER BUMP IN ROAD WHILE BRAKING FOR STOP LIGHT. THIRD TIME I HAVE PERSONALLY WITNESSED THIS MOMENTARY LOSS OF BRAKING. *TR

I HAVE A 2010 PRIUS AND AM ALSO HAVING BRAKE PROBLEMS. THE BRAKES INTERMITTENTLY SEEMS TO SLIP FOR A COUPLE SECONDS. IT SEEMS TO HAPPEN AT LOW SPEEDS, ON HILLS, AND IN THE MIDDLE OF THE TIME I AM PRESSING ON THE BRAKE. IT HAS HAPPENED BOTH WHILE CONTINUOUSLY PRESSING THE BRAKE AND ALSO AS I EASE OFF THE PRESSURE ON THE BRAKE. THE BEHAVIOR IS OCCASIONAL, BUT RECURRING. *TR

FEBRUARY 4, 2010 I OWN A 2010 PRIUS PURCHASED 09/01/09 BRAND NEW FROM A TOYOTA DEALERSHIP. ON SUNDAY, JANUARY 31, 2010 I WAS IN MY NEIGHBORHOOD APPROACHING A "T" INTERSECTION AT A STOP SIGN. THE MAIN ROADS HAD BEEN CLEARED OF ICE BUT THERE WAS SOME ICE REMAINING ON OUR STREET. I WAS TRAVELING VERY SLOWLY, PUT ON MY BRAKES AND NOTHING HAPPENED. THEN I TRIED PUMPING THE BRAKES SINCE I GOT NO RESPONSE OTHERWISE. I SLID THROUGH THE STOP SIGN, TRIED TO TURN MY TIRES TO THE LEFT TO AVOID THE CURB AND ENDED UP JUMPING THE CURB WITH BOTH FRONT TIRES. ON INSPECTION WHEN I GOT HOME (4 HOUSES DOWN FROM THE INCIDENT) I NOTICED THE RIM OF THE RIGHT TIRE HAD BEEN CRACKED AND THE TIRE HAD SOME DAMAGE. I HAD TO WORK ON MON & TUES AND DID NOT DRIVE THE CAR ON THOSE DAYS. YESTERDAY, 02/03/10 I TOOK THE CAR TO HIBDON TIRES (2 BLOCKS AWAY) SINCE THE DEALERSHIP IS OVER 30 MILES AWAY AND I WAS AFRAID TO DRIVE IT ON THE HIGHWAY. THEY PUT ON THE SPARE TIRE AND DETERMINED THAT THE PASSENGER RIM WAS NOT REPAIRABLE, THE DRIVER RIM WAS INTACT AND BOTH TIRES WERE INTACT AND REUSABLE. THEY INDICATED THE AXLE DID NOT APPEAR DAMAGED. I ORDERED ANOTHER TOYOTA RIM TO MATCH ($411.20) AND WITH AN ALIGNMENT ($65.00) I WAS QUOTED A TOTAL PRICE OF $512.26. I CALLED THE TOYOTA DEALER TODAY (02/05/10) AFTER READING THE MEDIA REPORTS ABOUT COMPLAINTS BY OTHER PRIUS OWNERS DESCRIBING THE VERY SITUATION THAT HAPPENED TO ME. I CANCELED MY ORDER WITH HIBDON AND HOPE TO HAVE MY CAR REPAIRED AT THE TOYOTA DEALERSHIP. I HAV

ON THREE OCCASIONS, MY 2010 PRIUS "LEAPT FORWARD" WHEN I DROVE OVER A MAN-HOLE COVER. I HAVE READ THE DESCRIPTION OF THE BRAKING ISSUE ON THE 2010 PRIUS AND IT SOUNDS EXACTLY LIKE MY EXPERIENCE. IT ONLY LASTS FOR A FRACTION OF A SECOND, BUT IT IS QUITE FRIGHTENING WHEN IT HAPPENS. *TR

I WAS READING A STORY TODAY ABOUT SOME REPORTED BRAKE PROBLEMS WITH THE 2010 PRIUS. I BOUGHT MINE BACK IN SEPTEMBER 2009. I HAVE NOT NOTICED ANY BRAKE PROBLEMS DURING THE WINTER ON SLIPPERY SURFACES, BUT JUST IN THE LAST WEEK(JANUARY 30-FEBRUARY 2, 2010) I HAVE HAD TWO INSTANCES ON ROUGH ROADS(FROM MELTING ICE CREATING SOME SMALL POTHOLES) WHILE BRAKING WHERE IT FEELS LIKE THE CAR EITHER ACCELERATES FOR A BRIEF MOMENT OR THE WHEELS SLIP. 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 REMEMBER IMMEDIATELY LOOKING UP TO SEE IF A CAR HAD HIT ME AND THERE WAS NOT A CAR CLOSE AT ALL. *TR

I HAVE A 2010 PRIUS BOUGHT IN SEPTEMBER. I HAVE EXPERIENCED THE SURGE WHILE BRAKING ABOUT 4 OR 5 TIMES IN 5,000 MILES OF DRIVING. I DIDN'T CONNECT IT WITH BRAKING AS IT WAS A SURGE. I THINK THAT THE ROADS WERE WET EACH TIME THIS HAPPENED. I STEPPED DOWN HARD EACH TIME AND THE SURGE DISAPPEARED AFTER ABOUT A SECOND OR SO. *TR

THE FOLLOWING DESCRIBES EXACTLY THE PROBLEM: " .... MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING OVER AN UNEVEN ROAD SURFACE, POTHOLE OR BUMP." I'VE HAD THIS HAPPEN SEVERAL TIMES SINCE I PURCHASED MY PRIUS IN NOV 2009, MOST RECENTLY THIS MORNING ON THE WAY TO WORK (GOING DOWN HILL!) ON THE ROAD. I'VE NEVER HIT ANYONE OR ANYTHING BUT THE RISK OF THAT HAPPENING IS THERE AND MUST BE ADDRESSED WITH A RECALL & REPAIR. *TR

CAR DID NOT BRAKE PROPERLY AND SLIGHTLY SURGED FORWARD ON MANY OCCASIONS WHEN I DROVE OVER A MANHOLE COVER AND SPEED BUMPS AT LOWER SPEEDS. IN ONE OCCASION, I REAR ENDED A CAR AND CRACKED MY LICENSE PLATE FRAME BUT SINCE THERE WAS NO FURTHER DAMAGE ON ANY OF THE CARS INVOLVED, WE AGREED TO DRIVE AWAY. *TR

THERE HAVE BEEN 3 INSTANCES WHERE THE BRAKES OF MY VEHICLE BRIEFLY STOPPED WORKING EFFECTIVELY. THESE INSTANCES ALWAYS OCCURRED WHEN I WAS ATTEMPTING TO BRAKE OVER ROUGH PAVEMENT OR POTHOLES. IT HAS NOT RESULTED IN AN ACCIDENT FOR ME YET, BUT HAVING JUST READ THAT THIS IS AN ISSUE FOR THE 2010 PRIUS, I THOUGHT IT IMPORTANT TO REPORT THAT I TOO HAVE EXPERIENCED THIS PROBLEM IN MY 2010 PRIUS. *TR

I HAVE A 2010 TOYOTA PRIUS THAT I BOUGHT IN DECEMBER, 2009. SIX OR SEVEN TIMES, I HAVE NOTICED THAT THE CAR LURCHES FORWARD (LIKE SOMEONE IS FLOORING THE GAS PEDAL) EVERY TIME I HIT A POT HOLE. I THOUGHT IT MIGHT BE JUST ME, BUT I SAW IN THE PAPER TODAY THAT OTHERS HAVE NOTICED SIMILAR PROBLEMS WITH THEIR PRIUS. *TR

THREE SEPARATE OCCASIONS OF MOMENTARY LOSS OF BRAKING GOING OVER ROUGH SURFACE (TWO DIFFERENT LOCATIONS) ON DRY ASPHALT. EACH TIME THE BRAKING RESUMED AFTER A SHORT MOMENT, AS THE BRAKE PEDAL WAS KEPT PRESSED. WHEN THE BRAKES WENT OUT, IT FELT AS IF THE CAR STARTED LURCHING FORWARD, CAUSING MOMENTARY PANIC WITH THE DRIVER AND THE PASSENGERS. LUCKILY THERE WAS STILL TIME TO GET TO A COMPLETE STOP BEFORE IMPACT. *TR

WE PURCHASED A 2010 PRIUS IN JUNE AND TOOK IT IN FOR SERVICING IN DECEMBER. AT THAT TIME WE REPORTED EXACTLY THE SAME PROBLEM THAT IS NOW IN THE NEWS -- WHEN BRAKING AT LOW SPEED THE VEHICLE OCCASIONALLY LURCHES FORWARD FOR AN INSTANT BEFORE SLOWING DOWN. AT THE TIME WE REPORTED IT, THE DEALER SAID THAT IT WAS JUST THE TRANSITION FROM ELECTRIC TO GAS AT THE MOMENT WE APPLIED THE BRAKES. IT NOW APPEARS TO BE A MORE SERIOUS PROBLEM SO I AM WRITING TO ADD OUR EXPERIENCE TO YOUR FILES. THIS PROBLEM DOES NOT HAPPEN OFTEN, BUT IT IS UNSETTLING WHEN IT DOES SINCE THE DRIVER DOES NOT EXPECT THE CAR TO ACCELERATE, EVEN MOMENTARILY, DURING BRAKING. IN A TIGHT SITUATION OR HEAVY TRAFFIC, THIS COULD EASILY CAUSE AN ACCIDENT. SO FAR WHEN IT HAS HAPPENED, THERE HAVE BEEN NO CONSEQUENCES, BUT IT IS SOMETHING WE WORRY ABOUT. THE DATE BELOW IS THE DATE WE REPORTED THE PROBLEM TO OUR TOYOTA DEALER. *TR

I WANT TO REGISTER A COMPLAINT THAT I AM EXPERIENCING LOSS OF BRAKING IN MY 2010 PRIUS WHEN THE CAR HITS A BUMP OR POT HOLE IN THE ROAD. HAVE BEEN IN CONVERSATIONS WITH TOYOTA PERSONNEL. NO SATISFACTION TO DATE WITH POSSIBLE FIX. NO ACCIDENTS HAVE OCCURRED THUS FAR WITH MY VEHICLE. IT HAS OCCURRED SEVERAL TIMES, MOST NOTABLY SINCE THE ROADS ARE GETTING ROUGHER AS A RESULT OF WINTER. *TR

BRAKES ON 2010 PRIUS SOMETIMES ARE "JERKY". THE PEDAL FEELS DIFFERENT AND I REQUIRE LESS OR MORE PRESSURE TO GET THE CAR TO BRAKE. OCCASIONALLY WHEN I PRESS THE BRAKE THE CAR JERKS TO A STOP INSTEAD OF A SLOW, CONTROLLED STOP. I HAVE BEEN DRIVING FOR OVER 20 YEARS & THE FEELING IS SIMILAR TO HOW I FELT IN LEARNING TO DRIVE WHEN I DIDN'T KNOW HOW MUCH PRESSURE TO USE ON THE BRAKE PEDAL. BOUGHT CAR IN OCTOBER 2009 - PROBLEM NOTED ABOUT 10 TIMES SINCE THAT DATE. *TR

I'VE EXPERIENCE BRAKING PROBLEMS WITH MY 2010 PRIUS. AS OTHERS HAVE REPORTED I TOO HAVE HAD AT LEAST A DOZEN INCIDENTS IN WHICH I AM APPLYING THE BRAKES AND THERE IS EITHER A BUMP IN THE ROAD OR MORE OFTEN A POTHOLE. USUALLY THIS HAS BEEN WHEN I WAS APPROACHING A STOP SIGN AND BRAKING MODERATELY. THE EXPERIENCE IS SUCH THAT THE BRAKES SEEM TO DISENGAGE AT THE TIME IN WHICH I HIT THE POTHOLE OR BUMP AND THE CAR LURCHES FORWARD FOR JUST A SPLIT SECOND. TO ME IT FEELS LIKE GOING OVER AN ICE PATCH AND THE SENSATION IS SIMILAR TO HYDROPLANING AS WELL. THIS HAS NOT CAUSED ANY ACCIDENT BUT DOES CONTRIBUTE TO A FEELING OF LOSE OF CONTROL AND CAUSES YOU TO POSSIBLY STOP A LITTLE LATER THAN YOU INTENDED TO. I HAVE 10,000 MILES ON THIS CAR AND HAVE HAD IT SINCE AUGUST 2009. I ALSO EXPERIENCE ANOTHER BRAKING ISSUE. SPORADICALLY WHEN I START THE CAR AND THE ENGINE HAS NOT COME ONE AND THE CAR IS ONLY USING BATTERY, THE BRAKES SEEM TO HAVE NO PLAY IN THE PEDAL. THE CAR STARTS TO MOVE AND WHEN I TAP THE BREAKS THEY JUST LOCK WITH A THUD AND THE PEDAL GOES ALL THE WAY TO THE FLOOR. I THEN RE STEP ON THE BRAKES AND THEY WORK PROPERLY AND FEEL NORMAL. THIS USUALLY HAPPENS IN MY DRIVEWAY OR PARKING LOTS AND MY FIRST REACTION IS THAT I HIT SOMETHING BECAUSE THE CAR SLAMS TO A STOP. *TR

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

I HAVE HAD MY 2010 PRIUS FOR ABOUT 45 DAYS, AND ON THREE OCCASIONS WHILE TRAVELING OVER BUMPY SURFACES AND VERY FIRMLY APPLYING THE BRAKES, I NOTICED A LACK OF STOPPING POWER FOR ABOUT HALF A SECOND RIGHT AFTER I HIT A BUMP. THEY WEREN'T TINY BUMPS, BUT THEY WEREN'T CRATERS EITHER. THE TRACTION OF MY TIRES DID NOT SEEM TO BE IMPAIRED. IT FELT LIKE THE BRAKES JUST LET OFF FOR A FRACTION OF A SECOND. *TR

2010 TOYOTA PRIUS- IF I DRIVE OVER A POTHOLE OR A MANHOLE COVER WHILE BRAKING, THE BRAKES FEEL LIKE THEY RELEASE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. HE STATED THAT WHILE DEPRESSING THE BRAKE PEDAL AT SPEEDS OF 10-15 MPH AND GOING OVER A ROCK OR A SPEED HUMP, THE BRAKES WOULD LOOSE TRACTION MOMENTARILY. THE DEALER WAS CONTACTED AND ADVISED THAT WAS A NORMAL FUNCTION OF THE ABS BRAKING SYSTEM. NO REPAIRS WERE MADE TO DATE. THERE WERE NO RECALLS. THE FAILURE AND CURRENT MILEAGES WERE UNDER 5100.

THE ISSUE WITH THE BRAKES ON THE 2010 PRIUS HAS OCCURRED SEVERAL TIMES ON OUR PRIUS, WHICH WAS PURCHASED IN AUGUST OF 2009. COMING DOWNHILL AND GOING OVER A SPEED BUMP THERE IS A SUDDEN SLIGHT ACCELERATION WHEN WE APPLY THE BRAKES. FORTUNATELY, NO ACCIDENT HAS OCCURRED. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN DRIVING OVER A ROUGH SURFACE WHILE DEPRESSING THE BRAKE PEDAL THE VEHICLE ACCELERATED; HOWEVER, THE FAILURE DID NOT RECUR ON SMOOTH ROAD SURFACES. THE FAILURE OCCURRED ON A WEEKLY BASIS. HE CALLED THE DEALER AND WAS TOLD THAT THERE WAS NOTHING THEY COULD DO TO REPAIR THE VEHICLE UNTIL THE MANUFACTURER ADVISED THEM. THE VEHICLE IDENTIFICATION NUMBER WAS UNAVAILABLE. THE CURRENT MILEAGE WAS APPROXIMATELY 5,000. THE FAILURE MILEAGE WAS APPROXIMATELY 20.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 30 MPH THE VEHICLE BECAME DIFFICULT TO STOP WHEN HE DROVE OVER SPEED BUMPS. THE CONTACT STATED THAT WHEN THE VEHICLE SURGED FORWARD IT FELT AS IF HE LOST BRAKING ABILITY. THE CONTACT HAS NOT TAKEN THE VEHICLE TO THE DEALER TO HAVE THE FAILURE DIAGNOSED. THE FAILURE HAS OCCURRED SINCE THE VEHICLE WAS PURCHASED. THE CONTACT IS CONCERNED THAT A CRASH COULD OCCUR IF THE VEHICLE CONTINUES TO LUNGE FORWARD. THE FAILURE MILEAGE WAS 4,500.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE BEGAN TO ACCELERATE WITHOUT WARNING WHILE DRIVING APPROXIMATELY 15 MPH OVER A POTHOLE. THE CONTACT WAS FORCED TO APPLY EXTREME PRESSURE TO THE BRAKE PEDAL IN ORDER TO STOP THE VEHICLE. THE DEALER ADVISED THE CONTACT THAT THE VEHICLE WILL CONTINUE TO RESPOND THAT WAY WHENEVER THE ELECTRICAL ENGINE SWITCHED TO THE GASOLINE ENGINE. THE FAILURE MILEAGE WAS 3,000.

MY 2010 TOYOTA PRIUS WAS A WEEK OLD. I WAS EXITING ON A SLOPING DOWNWARD RAMP FROM LAKE SHORE DRIVE IN CHICAGO AND GETTING READY TO STOP AND TURN RIGHT. ROAD CONDITIONS WERE WET AND COLD BUT NOT ICY. 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. I NOW HAVE 456 MILES ON THE ODOMETER. THE BRAKES HAVE NOT SLIPPED SINCE THE FIRST INCIDENT BUT I HAVE BEEN VERY CAUTIOUS IN APPLYING THEM IN SIMILAR SITUATIONS. *TR

WHILE TURNING OFF FOUR LANE ROAD ONTO FRONTAGE ROAD WITH FOOT ON BRAKE PEDAL MY CAR SUDDENLY STARTED ACCELERATING. I APPLIED MORE PRESSURE ON THE PEDAL QUICKLY AND GOT A SORT OF CLUNKING SOUND AND THE CAR RETURNED TO NORMAL DRIVING SPEED? *TR

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

2010 TOYOTA PRIUS. I HAVE EXPERIENCED ON AT LEAST 3 OCCASIONS, A SURGE WHEN GOING OVER A BUMP OR POTHOLE. I SPOKE TO MY LAW PARTNER ABOUT IT YESTERDAY. TODAY HE SHOWED ME THE INVESTIGATION YOU HAVE OPENED INTO THIS ISSUE. *TR

PULLING INTO A PARKING SPOT, HIT A SMALL BUMP, THE CAR LURCHED FORWARD WHILE MY FOOT WAS FIRMLY ON THE BRAKE. *TR

WHEN DRIVING MY 2010 PRIUS OVER BUMPS WITH MY BRAKES ON, THE CAR LUNGES FORWARD AS IF THE BRAKES ARE NOT WORKING. THIS OCCURS EACH TIME I HIT A BUMP WHEN I HAVE MY FOOT ON THE BRAKE PEDAL. *TR

I HAVE EXPERIENCED BRAKING ISSUES WITH A 2010 PRIUS PURCHASED IN JULY '09. WHILE BRAKING ON ICE OR SNOW WHEN FIRST DEPRESSING THE BRAKE PEDAL FOR LIGHT BRAKING NOTHING HAPPENS, NO BRAKING. WHEN THEN DEPRESSING THE BRAKE PEDAL MORE FIRMLY BRAKING THEN STARTS SUDDENLY BUT MORE AGGRESSIVE THAN DESIRED. THIS PROBLEM OCCURS ON ICE OR SNOW ONLY BUT I HAVE NOT DRIVEN ON EXTREME WASHBOARD OR GRAVEL ROADS. I HAVE HAD THE EXPERIENCE MORE THAN ONCE AND HAVE BEGUN TO ANTICIPATE IT HAPPENING REGULARLY ON ICE OR SNOW. *TR

ON MY 2010 TOYOTA PRIUS II (PURCHASED 9/30/2009, I HAVE NOTICED ON MULTIPLE OCCASIONS THAT WHILE I AM BRAKING, IF I HIT A POTHOLE, BUMP OR ROUGH PAVEMENT OF SOME TYPE, THE BRAKING SUDDENLY RELEASES FOR HALF-A-SECOND OR A SECOND. I AM MAINTAINING PRESSURE ON THE BRAKE PEDAL BUT WITH A BUMP, IT STOPS BRAKING MOMENTARILY. BECAUSE I TEND TO GIVE MYSELF A LOT OF ROOM TO BRAKE, NONE OF THESE INCIDENTS HAS LED TO AN ACCIDENT, BUT IT IS VERY DISCONCERTING. *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

1. SLOWING DOWN TO MAKE A RIGHT TURN, TRAVELING AROUND 15 MPH 2. WHILE TRAVELING OVER A POTHOLE OR UNEVEN ROAD SURFACE, BRAKES SUDDENLY DISENGAGED AND CAR CONTINUED FORWARD 3. BRAKES REENGAGED AFTER ABOUT A SECOND LATER. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN SHE WAS DRIVING OVER A SPEED BUMPS AND THE VEHICLE SUDDENLY ACCELERATED WITH HER FOOT ON THE BRAKE PEDAL. WHENEVER SHE DROVE THE VEHICLE THE FAILURE OCCURRED. SHE CALLED THE DEALER AND WAS ADVISED THAT THERE WAS NOTHING THEY COULD DO TO CORRECT THE FAILURE. SHE HAS NOT SPOKEN WITH THE MANUFACTURER TO-DATE. THE CURRENT MILEAGE WAS APPROXIMATELY 10,000. THE FAILURE MILEAGE WAS APPROXIMATELY 10.

I OWN A 2010 PRIUS PURCHASED IN JULY 2009. I HAVE ALSO (REGULARLY) FELT A SURGE FORWARD WHEN BRAKING AND HITTING A BUMP OR POTHOLE. BASED ON MY READINGS OF CHAT BOARDS I THOUGHT THIS WAS NORMAL, ALTHOUGH IT IS QUITE ALARMING WHEN IT HAPPENS. I'M NOT CONFIDENT THAT MY LOCAL TOYOTA DEALER WOULD BE ENTIRELY HONEST; WHEN I WAS IN FOR SERVICE DURING THE FLOORMAT BRAKE RECALL I OVERHEARD A SERVICE MANAGER TELLING A CUSTOMER IT WAS NOTHING TO WORRY ABOUT; IT WAS ONLY WHEN PEOPLE PUT NON-MANUFACTURER'S FLOORMATS ON TOP OF THE TOYOTA ONES THAT THERE WAS A PROBLEM (WHICH IS NOT MY UNDERSTANDING). I'D LIKE TO BE KEPT INFORMED OF THE STATUS OF THE INVESTIGATION IF AT ALL POSSIBLE. I'LL PUT IN EARLY AUGUST AS THE "INCIDENT DATE" BUT IT HAPPENS REGULARLY (AT LEAST ONCE A WEEK?) *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 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

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE LUNGED FORWARD AND ACCELERATED WHILE THE CONTACT WAS DRIVING APPROXIMATELY 20 MPH AND ATTEMPTING TO ENGAGE THE BRAKE PEDAL. THE VEHICLE WAS DIAGNOSED BY THE DEALER WHO CONFIRMED THAT IT RESPONDED NORMALLY SINCE THE ELECTRICAL ENGINE SWITCHED OVER TO THE GASOLINE ENGINE. THE CONTACT OBSERVED THAT THE MALFUNCTION OCCURRED CONTINUOUSLY. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 17,000.

2010 PRIUS WITH ABS PROBLEM. ON UNEVEN SURFACES (I.E. POTHOLES) OR ICY ROADS I HAVE NOT HAD 3 EVENTS WHERE THE BRAKES WERE NOT EFFECTIVE. ONE SITUATION WAS SO BAD AND ALMOST CAUSED A SERIOUS ACCIDENT UNDER SNOW/ICY CONDITIONS THAT I BROUGHT THE CAR TO TOYOTA IMMEDIATELY. I HAVE A SERVICE RECORD OF THAT IN MID DECEMBER 2009. THE SERVICE DEPARTMENT KEPT MY VEHICLE FOR A COUPLE DAYS AND DID ICY ROAD TESTING BUT NEVER FULLY RECREATED THE SITUATION. I HAVE DOCUMENTATION FROM THE SERVICE DEPARTMENT ON THIS DESPITE THEIR NOT ACKNOWLEDGING A PROBLEM. I HAVE A LOT OF RECOLLECTION OF THE DETAILS LEADING UP TO THE 3 SCENARIOS THAT HAVE OCCURRED NOW AND CAN LIKELY GIVE GOOD INSIGHT. BTW, FROM THE STORIES I READ TODAY IN THE PRESS I THINK TOYOTA (AND THE STORIES) HAVE THE PROBLEM MOSTLY DESCRIBED. I STILL HAVE OTHER CONCERNS BASED ON MY EXPERIENCES FROM THE 3 EVENTS. *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. THEY TOOK MY NAME ONLY WHEN I PRESSED THEM TO PUSH THE INFORMATION BACK TO TOYOTA MANAGEMENT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING SPEEDS OF LESS THAN 15 MPH OVER A POTHOLE, THE BRAKES MALFUNCTIONED AND RESET THEMSELVES WITHIN MINUTES WITHOUT HAVING TO SHUT THE ENGINE OFF. NEITHER THE MANUFACTURER NOR DEALER WAS CONTACTED. THERE WERE NO RECALLS. THE FAILURE AND CURRENT MILEAGES WERE 2200.

I HAVE NOTICED THE TEMPORARY LOSS OF BRAKING IN MY BRAND NEW 2010 TOYOTA PRIUS PURCHASED IN DECEMBER 2009. WHEN BRAKING ON UNEVEN GROUND, IF YOU HIT A POTHOLE IN THE ROAD THE CAR LURCHES FORWARD AND IT FEELS LIKE YOU HIT THE ACCELERATOR. PLEASE ENCOURAGE TOYOTA TO ADDRESS THIS ISSUE. *TR

2010 TOYOTA PRIUS BRAKE PROBLEM. THIS OCCURS WHEN HITTING A BRAKE WHEN ON SOME SORT OF ROUGH ROAD AREA, LIKE A POTHOLE OR A BUMP. IT FEELS LIKE EITHER THE BRAKE ISN'T ENGAGING OR IT'S SPEEDING UP. IT'S HARD TO TELL. EITHER WAY, IT'S SCARY AND IT CAN CAUSE AN ACCIDENT. FOR INSTANCE, IF YOU'RE DRIVING IN MANHATTAN AND YOU HIT A POTHOLE AS YOU BRAKE WITH A CAR IN FRONT OF YOU. (I WAS LUCKY WHEN THIS PROBLEM KICKED IN AND I HIT THAT POTHOLE AS THERE WAS NO CAR IN FRONT OF ME AT THE TIME.) THIS PROBLEM HAS HAPPENED TO ME CLOSE TO 10 TIMES NOW. PLEASE NOTE THAT THIS HAS HAPPENED NUMEROUS TIMES. IT HAPPENED WITHIN A COUPLE DAYS OF WHEN I GOT THE CAR. I DIDN'T SEE "BRAKES" ON YOUR LIST OF PARTS THAT WERE DEFECTIVE. I DID SEE "SERVICE BRAKES" IN 3 CATEGORIES, BUT I DIDN'T KNOW IF "SERVICE BRAKES" WAS SOME SPECIAL MEANING, NOR DID I KNOW WHICH KINDS OF BRAKES HAD THE PROBLEM (OR EVEN WHICH KIND THE CAR HAS). *TR

I HAVE A 2010 PRIUS III WITH BRAKE ISSUES. SPORADICALLY, WHEN DRIVING BACKWARDS FROM A PARKED POSITION THE BRAKES BECOME INCREDIBLY SENSITIVE AND I HAVE TO TURN OFF THE CAR AND TURN IT BACK ON AGAIN FOR THEM TO FUNCTION NORMALLY. ON ABOUT 01/17/2010, AFTER A HEAVY RAIN, WHEN I WAS AGAIN PULLING BACKWARDS OUT OF MY DRIVEWAY MY BRAKES MADE A GRINDING SOUND AS IF THE PADS WERE GONE. MIND YOU I HAVE LESS THAN 9,000 MILES ON THE CAR. AGAIN, TURNED OFF THE CAR AND BACK ON TO FIX. HAS NOT HAPPENED AGAIN BUT IT HASN'T RAINED EITHER. *TR
