2010 Toyota Prius complaints

BRAKING PROBLEM NOTED WITH PRIUS 2010. ON UNEVEN PAVEMENT WHILE STRONGLY BRAKING, THE CAR LURCHES FORWARD FOR A MOMENT, PRIOR TO FINALLY BRAKING (FELT AS THOUGH IT WAS "SLIPPING" UNTIL IT CAUGHT THE PAVEMENT AGAIN). THIS HAS OCCURRED APPROXIMATELY 5 - 6 TIMES SINCE PURCHASE 07/31/09. CONTACTED SERVICE DEPT. IN 2009 BY PHONE, BUT THEY HAD NO OTHER COMPLAINTS. AT SOME LEVEL I WAS THINKING IT WAS JUST MY IMAGINATION OR SOME KIND OF HIGH TECH GLITCH THAT I HAD TO LIVE WITH. AT SERVICING IN JANUARY ALL SYSTEMS WERE ASSESSED WITHOUT ABNORMALITY, ALTHOUGH I DID NOT FORMALLY COMPLAIN ABOUT MY BRAKES AT THAT TIME. THE ISSUE REMAINS, AND I DO BELIEVE THAT IT IS A SAFETY ISSUE, AND THAT REAR-ENDING ANOTHER VEHICLE IS A REAL POSSIBILITY DUE TO LACK OF CONTROL. *TR

WHEN SLOWING FOR A STOP SIGN - I STRUCK A BUMP IN THE ROAD AND THE BRAKE DID NOT FEEL LIKE IT APPLIED FOR A QUICK MOMENT. IT CAUSED ME TO STOP FURTHER IN TO THE INTERSECTION THAN I EXPECTED, OR WOULD HAVE LIKED. *TR

SINCE PURCHASING MY 2010 PRIUS IN OCTOBER 2009 I HAVE NOTICED A BRIEF PULSATING SENSATION WHEN APPLYING THE BRAKES OVER BUMPING SURFACES. THE BRAKES APPEAR NOT TO WORK FOR THAT BRIEF MOMENT WHEN APPLYING THE BRAKES.*TR

I HAVE A 2010 PRIUS. WHEN I AM COMING TO A STOP AND THERE IS A SLOPE IN THE ROAD OR A POTHOLE, THE BRAKES WILL MOMENTARILY DISENGAGE AND THE CAR LUNGES FORWARD. IT HAS HAPPENED MULTIPLE TIMES. I CAN PREDICT WHEN IT IS GOING TO HAPPEN BASED ON THE BUMPINESS OF THE ROAD. AND THE DISTANCE I AM FROM COMING TO A COMPLETE STOP. *TR

I OWN A 2010 TOYOTA PRIUS PURCHASED NEW IN OCTOBER 2010. I HAVE HAD AT LEAST 5 INSTANCES OF THE BRAKE FAILURE THAT HAVE BEEN DESCRIBED IN RECENT REPORTS. THE FAILURE OCCURS WHEN BRAKING AND GOING OVER A ROUGH SPOT LIKE A MAN-HOLE COVER OR POTHOLE. THERE IS A MOMENTARY AND COMPLETE FAILURE OF THE ENTIRE BRAKING SYSTEM. *TR

MY 2010 PRIUS (PURCHASED 6/30/09) LURCHES FORWARD WHEN I HIT A POTHOLE OR A SHARP BUMP IN THE ROAD WHILE I HAVE THE BRAKES ON. IT HAS HAPPENED ABOUT 3 TIMES SINCE I'VE HAD THE CAR. *TR

WHEN DRIVING OVER UNEVEN TERRAIN (IE.; RAILROAD TRACKS, BUMPS IN THE ROAD) MY 2010 PRIUS SEEMS TO ACCELERATE. I READ ABOUT THE BRAKES FAILING... BUT IT REALLY FEELS LIKE IT IS ACCELERATING TOO. IT IS VERY SCARY WHEN THIS HAPPENS AS IT FEELS THAT YOU WILL BE THRUSHED INTO WHATEVER MIGHT BE IN FRONT OF YOU. *TR

I COULDN'T STOP MY 2010 PRIUS AT A STOP. THE BRAKES WOULDN'T STOP THE VEHICLE.*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. THIS HAS OCCURRED SINCE I BOUGHT THE CAR IN AUGUST 2009. *TR

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. THIS HAS ONLY OCCURRED A SINGLE TIME SINCE PURCHASING THE VEHICLE IN JULY, 2009. *TR

ON 8-21-09, I TOOK DELIVERY ON A 2010 TOYOTA PRIUS HYBRID. SINCE TAKING DELIVERY, I HAVE EXPERIENCED INTERMITTENT ,MOMENTARY ,UNINTENDED ACCELERATION AND INTERMITTENT,MOMENTARY LOSS OF BRAKING. 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. BUT WHEN I HEARD TODAY 2-4-10, THAT THE NHTSA WAS OPENING AN INVESTIGATION OF THE 2010 PRIUS, I DECIDED TO ADD MY COMPLAINT TO THE OTHERS. *TR UPDATED 03/04/10 *BF

TOYOTA PRIUS 2010. WHILE DRIVING APPROX 20 MPH OVER A POTHOLE WHILE APPLYING THE BRAKES, I FELT WHAT SEEMED LIKE THE BRAKE SLIP AND RELEASE TEMPORARILY. ALTHOUGH IT DID NOT CAUSE AN ACCIDENT, IT COULD HAVE HAD THERE BEEN A CAR CLOSER ON THE OTHER SIDE OF THE POTHOLE. *TR

WHEN APPLYING BRAKES ON 2010 PRIUS (PURCHASED IN SEPT 2009), THE CAR LURCHES FORWARD WHEN IT HITS A BUMP IN THE ROAD. THIS IS A REPRODUCIBLE BEHAVIOR AND HAS BEEN OBSERVED SINCE SHORTLY AFTER PURCHASE. *TR

2010 TOYOTA PRIUS: AFTER TURNING CAR ON, TAKING EMERGENCY BRAKE OFF, FOOT ON BRAKE PEDAL FULLY DEPRESSED, SHIFTING FROM PARK INTO REVERSE, THE CAR WILL BEGIN TO MOVE ON ITS OWN WITHOUT ME TAKING FOOT OFF BRAKE. HAVE TO SHIFT IT BACK TO PARK AND TURN IT OFF FOR IT TO STOP. TOYOTA SERVICE SAID "THIS IS NORMAL". HAS HAPPENED 8 TIMES, MOST RECENT JAN 15TH. ALL ON LEVEL SURFACES. ONLY HAPPENS IF CAR IS ON IN ELECTRIC MODE ONLY, NOT WITH THE ENGINE ON. *TR

I HAVE EXPERIENCED BRAKE ISSUES ABOUT 6 TIMES, AND MY WIFE HAS HAD IT HAPPEN TO HER TWICE, SINCE I BOUGHT MY 2010 PRIUS AT THE END OF AUGUST 2009. THE BRAKE PROBLEM USUALLY WILL HAPPEN WHEN BRAKING ON AN UNEVEN SURFACE SUCH AS A POTHOLE OR A BUMPY ROAD. THE ISSUE IS THAT THE BRAKES WILL MOMENTARILY STOP WORKING AND YOU GET A JERKING/SPEEDING UP FEELING. *TR

DRIVING A BRAND NEW 2010 TOYOTA PRIUS IV APPROACHING A SET OF RR TRACKS. WHILE BRAKING TO MAKE A LEFT TURN I CROSSED THE TRACKS. THE PRIUS SURGED FORWARD AND I ALMOST COLLIDED WITH THE AUTOMOBILE IN FRONT OF ME. *TR

PRESSING BRAKES WHILE TURNING AND HITTING A POTHOLE CAUSES CAR TO SURGE FORWARD. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES WERE ULTRA-SENSITIVE AND WHILE DRIVING 5 MPH IN REVERSE AND LIGHTLY DEPRESSED THE PEDAL THE VEHICLE LUNGED FORWARD AS IF SHE MADE AN ABRUPT STOP. OCCASIONALLY, SHE HAD TO PUSH THE BRAKE PEDAL EXTREMELY HARD TO STOP THE VEHICLE. SHE HAS NOT SPOKEN TO THE DEALER NOR THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS 3,740. THE FAILURE MILEAGE WAS APPROXIMATELY 500.

MY PRIUS LOSES ITS BRAKING ABILITY WHEN I HIT A POTHOLE OR IF I DRIVE OVER A SEWER GRATE. I'VE OWNED THE CAR SINCE JULY 2009, IT IS A 2010 MODEL. IT ALSO HAPPENS WHEN I DRIVE OVER BUMPS IN THE ROAD. THIS HAS HAPPENED SEVERAL TIMES SINCE JULY. IT SEEMS TO HAPPEN MORE IN WET WEATHER. *TR

I PURCHASED A 2010 PRIUS IN OCTOBER, 2009. ON SEVERAL OCCASIONS I HAVE BEEN BRAKING AND HIT A POTHOLE OR BUMP IN THE ROAD AND MY VEHICLE HAS ACCELERATED MOMENTARILY. THE FIRST COUPLE OF TIMES THIS HAPPENED, IT WAS RATHER CONCERNING AND DANGEROUS, AS I WAS CONCERNED I'D HIT THE VEHICLE IN FRONT OF ME. SINCE THEN, I ATTEMPT TO NOT BRAKE DIRECTLY OVER A POTHOLE. *TR

BRAKES FAIL MOMENTARILY WHEN DRIVING OVER POTHOLES AND BUMPS. *TR

SOMETIMES WHEN I'M BRAKING IT FEELS LIKE A SURGE IN POWER OF MY TOYOTA PRIUS - 2010. *TR

MY 2010 TOYOTA PRIUS, PURCHASED IN JULY 2009, EXPERIENCES BRAKING PROBLEMS ON WET OR SLIGHTLY BUMPY ROADS. WHEN I HIT THE BRAKE, THE CAR JUMPS FORWARD IN THESE CONDITIONS. IF I WERE TAILGATING THE CAR BEFORE ME, IT COULD CRASH. *TR

AS OWNER OF A 2010 TOYOTA PRIUS WITH ABOUT 10,000 MILES ON IT, MY WIFE (THE REGULAR DRIVER) AND MYSELF HAVE EXPERIENCED AN ANOMALY IN BRAKE OPERATION ON SEVERAL OCCASIONS. EACH OCCASION INVOLVES EITHER HITTING A BUMP IN THE ROAD WHILE BRAKING OR BEING ON WET PAVEMENT WHILE BRAKING. WHEN THIS HAPPENS, IF FEELS AS IF THE BRAKES RELEASE FOR A FRACTION OF A SECOND (CREATING A SHORT SENSATION OF ACCELERATION) AND THEN RESUME OPERATION. I DON'T THINK THE CAR IS ACTUALLY ACCELERATING IN THAT MOMENT. MY THEORY IS THAT WHILE BRAKING, A SINGLE WHEEL LOOSES TRACTION (AND PERHAPS MOMENTARILY STOPS) AND THEN THE SYSTEM RELEASES ALL WHEELS FOR A MOMENT BEFORE REGULAR BRAKING RESUMES. THE FACT THAT YOU ARE SITTING IN THE CAR WITH YOUR FOOT APPLYING PRESSURE ON THE BRAKE MAKES THIS VERY ATTENTION GETTING. THIS HAS OCCURRED SEVERAL TIMES SINCE GETTING THE CAR LAST AUGUST. *TR

WHEN OUR 2010 PRIUS HITS A POTHOLE AND I BRAKE, IT LUNGES FORWARD FOR A SECOND. THIS HAS HAPPENED 3 TIMES. *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

OUR 2010 PRIUS HAS A PROBLEM WITH THE BRAKES WHEN GOING OVER BUMPY ROADS. *TR

I PURCHASED A 2010 TOYOTA PRIUS ABOUT 6 WEEKS AGO AND HAVE EXPERIENCED A BRAKE SURGE PROBLEM AT LEAST THREE TIMES. IN EACH INSTANCE I WAS TRAVELING ABOUT 20 MPH AND HAD APPLIED THE BRAKES. WHEN THE CAR HIT A BUMP IN THE PAVEMENT IT SURGED FORWARD FOR ABOUT 0.5 SECOND BEFORE THE BRAKES GRABBED AGAIN. THE ROAD SURFACE WAS DRY ON EACH OCCASION AND MY IMPRESSION AT THE TIME WAS THAT THE BRAKES JUST LET GO. *TR

UPON APPLYING THE BRAKES WHEN I HIT ROUGH ROAD, POT HOLE, DEBRIS, UNLEVEL PAVEMENT, THEY SEEM TO SLIP. I DON'T SLOW DOWN LIKE I WANT THE CAR TO, I FISHTAIL A LITTLE AND THE STABILITY CONTROL COMES ON. THIS HAS HAPPENED 3 OR 4 TIMES SINCE I PURCHASED THE CAR. 2010 TOYOTA PRIUS. *TR

I OWN A 2010 TOYOTA PRIUS THAT I PURCHASED IN THE FALL OF 2009. ON SEVERAL OCCASIONS I HAVE DEPRESSED MY BRAKE PEDAL TO EITHER SLOW DOWN OR STOP BUT , INSTEAD, THE VEHICLE BRIEFLY ACCELERATES AND GIVES A FEELING OF "SKIPPING" OVER THE BRAKING ACTION. THE VEHICLE THEN QUICKLY CORRECTS BEFORE STOPPING OR SLOWING DOWN. THIS HAS HAPPENED ON MORE THAN ONE OCCASION ON VERY SPECIFIC TYPES OF TERRAIN THAT I CAN DESCRIBE AS BUMPY OR UNEVEN. I PLACED A CALL TODAY WITH MY TOYOTA DEALERSHIP IN WHICH I EXPLAINED THE ABOVE NARRATIVE TO THEM. THEY RESPONDED WITH IGNORANCE TO THE SITUATION AND STATED THAT THEY WILL WAIT TO HEAR FROM TOYOTA ON THE MATTER. *TR

I OWN A 2010 TOYOTA PRIUS, WHICH I PURCHASED IN AUGUST, 2009. I HAVE EXPERIENCED A BRAKING PROBLEM AT LEASE 6 TIMES SINCE THEN. WHEN I BRAKE WHILE DRIVING OVER ROUGH ROADS INCLUDING DRIVING OVER METAL COVER PLATES IN ROADS, I LOSE ALL MY BRAKES FOR A SECOND OR SO. IT FEELS LIKE I HAVE HIT A PATCH OF ICE. IT IS VERY SCARY, AND REALLY GETS YOUR ATTENTION. *TR

TOYOTA 2010 PRIUS - PROBLEM WITH CAR ACCELERATING WHEN I BRAKE ON BUMPY SURFACE. HAS OCCURRED REPEATEDLY AS ON MY DRIVE TO WORK I DRIVE OVER A POTHOLED SECTION OF ROAD AND NEED TO BRAKE TO SLOW DOWN FOR A RIGHT HAND TURN -IF I GO VERY SLOWLY AND DO NOT BRAKE ON THE BUMPY PART IT DOES NOT OCCUR - WHEN I DRIVE AT A NORMAL SPEED AND BRAKE FOR THE TURN IT DOES OCCUR - I FEEL A MAJOR ACCELERATION THAT LASTS FOR ONLY A SECOND OR TWO. *TR

SHE WILL TAKE THE VEHICLE BACK TO THE DEALER TO BE DIAGNOSED. THE FAILURE MILEAGE WAS 4 AND THE CURRENT MILEAGE WAS 5,600. UPDATED 08/12/10

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

WHILE DRIVING WITH CRUISE CONTROL ENGAGED AND A SITUATION OCCURS THAT REQUIRES BRAKING; NORMAL BRAKE PEDAL PRESSURE DOES NOTHING. I HAVE TO HIT THE BRAKES EXTRA HARD WHICH SIGNIFICANTLY SLOWS REACTION TIME. THIS PROBLEM OCCURS RANDOMLY. WHEN I TOOK THE CAR TO THE DEALER I COULD NOT GET THE PROBLEM TO REPEAT. *TR

AFTER STOPPING THE CAR, THEN EITHER MOVING FORWARD OR REVERSING, BRAKES WILL GRAB. BRAKE GRAB IS STRONG ENOUGH THAT IT FEELS LIKE I'VE SLAMMED ON THE BRAKES WHEN THEY ARE BARELY TOUCHED. IN ORDER TO CORRECT, I PUT THE CAR IN PARK, THEN EITHER D OR R. THIS HAS HAPPENED ABOUT 10 TIMES SINCE I BOUGHT THE CAR IN AUGUST 2009. *TR

WHILE DRIVING NORTHWEST ON NATIONAL BL, JUST PAST VENICE BLVD, IN MY 2010 PRIUS, I APPLIED THE BRAKES AND, RATHER THAN SLOWING, THE CAR ACCELERATED FORWARD. I RELEASED THE BRAKE AND PRESSED IT AGAIN, VERY FIRMLY, AND THE BRAKES FINALLY CAUGHT. *TR

2010 TOYOTA PRIUS II STOPPING TIME LONGER THAN EXPECTED WHEN IN "B" GEAR AND NEED TO BRAKE. NOTE THAT I AM NOT SURE OF THE ROAD SURFACE WHEN THIS OCCURRED BUT I BELIEVE THAT IT WAS FLAT. CAR SEEMS TO LURCH FORWARD. HAVE COME CLOSE TO HITTING CAR IN FRONT OF ME. DRY ROAD SURFACE, CLOSE TO 50 DEGREES F. *TR

2010 TOYOTA PRIUS (BOUGHT IN 10/2009). WHEN GOING OVER A RECESSED MANHOLE COVER OR POTHOLE WHILE BREAKING, IT FEELS AS IF THE BRAKE IS SLIPPING AND THE CAR JERKS FOR A MOMENT. CONTINUED PRESSURE ON THE BRAKE BRINGS THE CAR TO A STOP. IT HAS NEVER HAPPENED EXCEPT WHEN GOING OVER SOME OBSTRUCTION AND ONLY WHEN TRAVELING OVER 20 MPH. GOING OVER SPEEDBUMPS IN A PARKING LOT IS FINE. *TR

WE HAVE A 2010 TOYOTA PRIUS II, AND HAVE EXPERIENCED MULTIPLE INSTANCES OF THE BRAKES NOT WORKING - ESPECIALLY WHILE DRIVING THROUGH OUR APARTMENT COMPLEX AND GOING OVER SPEED BUMPS. THIS HAS ALSO OCCURRED WHILE ON THE INTERSTATE, SLOWING DOWN FOR TRAFFIC. THE DATE LISTED BELOW IS FOR THE MOST RECENT OCCURRENCE. *TR

WE HAVE TOYOTA PRIUS 2010 MODEL AND THERE HAS BEEN INCIDENCES IN THE PAST COUPLE OF MONTHS WHERE THE BRAKES HAVE NOT FUNCTIONED PROPERLY. ON DEC 7TH 2009 ON A TRAFFIC LIGHT SIGNAL MY CAR DESPITE APPLYING THE BRAKES KEPT ON MOVING AND ENDED UP HITTING ANOTHER CAR. MY CAR WAS DAMAGED BUT I JUST COULDN'T COMPREHEND THE REASON AS TO WHY THE CAR DIDN'T STOP. EVEN AFTER COUPLE OF WEEKS WHEN MY HUSBAND WAS DRIVING, WHILE WE WERE STOPPED AT THE TRAFFIC LIGHT, THE CAR KEPT ROLLING FORWARD. ALL WE COULD THINK WAS THAT MAY BE WE WERE NOT PRESSING THE BRAKES HARD ENOUGH, BUT SINCE OTHER PEOPLE HAVE COME OUT WITH SIMILAR PROBLEM WITH PRIUS, THE WHOLE THING IS MAKING SENSE TO US. I USE PRIUS REGULARLY WITH MY TWO YOUNG KIDS IN THE BACK BUT NOW I AM SCARED TO EVEN DRIVE IT. *TR

MY 2010 PRIUS ACCELERATES WHEN IT HITS A POT HOLE WHILE SLOWING DOWN. THIS HAPPENS MORE WHEN THERE IS SNOW OR ICE ON THE ROAD. IN ICY CONDITIONS I AM SLOWING DOWN AND NOT PRESSING ON THE BRAKE, BUT IF IT HITS A POT HOLE -- A MOMENTARY LOSS OF CONTROL IS EXPERIENCE. IT SEEMS LIKE THE ELECTRIC BRAKE SWITCHES OFF AND HYDRAULIC BRAKES KICKS IN BECAUSE IT BRAKES HARDER ONCE BACK. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 5 MPH OVER RAILROAD TRACKS WITH HIS FOOT ON THE BRAKE PEDAL, THE VEHICLE ACCELERATED ON ITS OWN. THE FAILURE DOES NOT OCCUR WHILE DRIVING OVER SMOOTH ROAD SURFACES. THE DEALER HAS NOT BEEN CONTACTED. NO REPAIRS WERE MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 2000 AND THE CURRENT MILEAGE WAS 11000.

MOMENTARY LACK OF BRAKING ON 2010 TOYOTA PRIUS BOUGHT SUMMER OF 09. HAS HAPPENED MANY TIMES. ALSO BRAKES GRAB ERRATICALLY JERKING THE CAR SEVERELY WHEN IN REVERSE. SAME PROBLEMS ARE NOTED BY MANY, MANY OWNERS ON PRIUSCHAT.COM FORUM.*TR

ISSUE WITH BRAKES OF PRIUS 2010. WE LOSE SOME CONTROL OF THE VEHICLE OR IT VEERS WHEN THE BRAKES ARE PUSHED SOMETIMES. IT HAPPENS VERY RARELY BUT WHEN WE PUSH THE BRAKE, THE CAR WILL SOMETIMES SEEMS TO SLOW, THEN ACCELERATE A COUPLE OF FEET BEFORE STOPPING. *TR

I HAVE A NEW 2010 TOYOTA PRIUS THAT I BOUGHT IN DEC 2009. I DID EXPERIENCE SOMETHING THAT SOUNDS SIMILAR TO THE BRAKE PROBLEM NOW BEING INVESTIGATED - A MOMENTARY LOSS OF BRAKE POWER WHILE GOING OVER A POTHOLED/BUMPY PATCH OF ROAD. IT WAS JUST FOR A MOMENT AND NO ACCIDENT RESULTED, BUT I AM WORRIED NOW THAT THE PROBLEM MIGHT NOT HAVE JUST BEEN A RANDOM FLUKE. SEPARATELY, I HAD ANOTHER STRANGE INCIDENT WITH THE CAR. BACKING OUT OF A PARKING SPACE, I HAD NOT YET HIT THE ACCELERATOR BUT THE CAR IMMEDIATELY JUMPED BACKWARDS AS THOUGH I HAD HIT THE GAS HARD. THE ONLY WAY PREVENT IT FROM BUCKING BACKWARDS WAS TO HIT THE BRAKE. I HAD TO SORT OF JOLT OUT OF THE PARKING SPACE BECAUSE THERE WAS NO IN BETWEEN OF NORMAL/SLOW ACCELERATION. ONCE I GOT OUT OF THE SPACE AND PUT THE CAR INTO DRIVE, IT WAS ACCELERATED NORMALLY. *TR
