2010 Toyota Prius Complaint Log

DRIVING MY 2010 PRIUS TODAY, I EXPERIENCED A BRAKE FAILURE SUCH AS THE ONE I'VE BEEN HEARING ABOUT ON THE NEWS. HERE'S WHAT HAPPENED: I WAS BRAKING, SLOWING TO A STOP APPROACHING A STOPLIGHT (GOING NO FASTER THAN 10 MPH AT THE TIME), MY CAR ROLLED OVER A MANHOLE COVER THAT WAS SLIGHTLY LOWER THAN THE SURFACE OF THE ROAD (NO MORE THAN ONE INCH DEEP) AND SUDDENLY IT FELT LIKE MY CAR WAS GLIDING ON ICE WITH NO ABILITY TO STOP, THE BRAKES HAD COMPLETELY FAILED; ADDITIONALLY, I HEARD A SLIGHT GRINDING SOUND COME FROM THE FRONT RIGHT WHEEL WELL. I TOOK MY FOOT OFF THE BRAKE, RE-DEPRESSED THE PEDAL, AND EVERYTHING WAS INSTANTLY BACK TO NORMAL. THE DURATION OF THE INCIDENT WAS NO MORE THAN A SECOND, BUT IT WAS TERRIBLY ALARMING JUST THE SAME. FOLLOWING THIS INCIDENT, I HAVE CONTACTED TWO DIFFERENT TOYOTA DEALERSHIPS' SERVICE DEPARTMENTS WHO STATED THAT THEY DID NOT CURRENTLY HAVE ANY REPAIR PLANS FOR THIS PROBLEM, APOLOGIZED FOR THE "INCONVENIENCE," AND ONE OF THE DEALERSHIPS (TOYOTA OF HOLLYWOOD (CA)) TOOK MY PHONE NUMBER WHILE THE OTHER DEALERSHIP TOLD ME TO WAIT FOR A LETTER FROM TOYOTA. I INQUIRED OF TOYOTA OF GLENDALE (CA) IF I SHOULD GET A RENTAL CAR FOR THE TIME BEING (HOPING TO BE OFFERED A LOANER) AND THEY TOLD ME NOT TO, AND TO 'DRIVE SAFE.' I'M TOTALLY LIVID, THIS IS A VERY SCARY PROBLEM TO EXPERIENCE. *TR

MY 2010 TOYOTA PRIUS ACCELERATES SUDDENLY COMING TO A STOP AND GOING OVER A BUMP. IT HAS HAPPENED SEVERAL TIMES SINCE I BOUGHT THE CAR LAST JULY (TWICE TODAY). ALSO, IT HANDLES TERRIBLY IN THE SNOW, SKIDDING THROUGH TURNS AND WHEN BRAKING. I HAVE BEEN DRIVING IN THE SNOW FOR 30 YEARS AND HAVE NEVER HAD A CAR THAT HANDLES SO POORLY. *TR

AS I SLOW DOWN IN MY 2010 TOYOTA PRIUS, IF THE CAR GOES OVER ANY BUMPS, I FEEL AN "ACCELERATION" (ACTUALLY A SUDDEN STOP IN DECELERATION) AS I AM APPLYING THE BRAKES. I WENT TO MY TOYOTA DEALER AND THEY ACKNOWLEDGED THAT THEY'D HEARD OF THE ISSUE, BUT DENIED IT WAS A PROBLEM. *TR

TOYOTA PRIUS 2010 PURCHASED JULY 2009. THIS VEHICLE HAS THE BRAKING PROBLEM WHICH IS DESCRIBED IN THE MEDIA. THE BRAKE "INTERMITTENT RELEASE" ON UNEVEN ROAD SURFACE IS REPEATABLE AND HAS BEEN SYMPTOMATIC SINCE NEW. *TR

TOYOTA PRIUS 2010 MODEL - BOUGHT JULY 2009 - PERIODICALLY (TAKEN PLACE OVER A PERIOD OF 6 MONTHS OR SO) WHEN PRESSING THE BRAKE PEDAL, THERE IS A SHORT PERIOD OF TIME WHEN IT IS APPARENT THAT NO BRAKING ACTION IS TAKING PLACE AND THAN ALL OF A SUDDEN YOU CAN TELL THAT THE BRAKING ACTION HAS TAKEN PLACE. IT IS SCARY WHEN THIS TAKES PLACE. I DO HAVE AN APPOINTMENT WITH THE DEALER THIS COMING WEEK. *TR

AT 15 MPH AND BRAKING, BRAKES DISENGAGE FOR LESS THAN ONE SECOND AFTER HITTING A ROAD IMPERFECTION (AN OLD METAL AND RUBBER SENSOR PLACED ABOUT 10 OR 15 FEET FROM CROSSWALK) THAT IS PERPENDICULAR TO DRIVING DIRECTION. AT 35 MPH, BRAKES DISENGAGE WHEN BRAKING AND CROSSING A BRIDGE/OVERPASS CONNECTOR PLATE. *TR

BRAKING ON ROUGH SURFACE RESULTS IN CAR JUMPING FORWARD AND THEN EVENTUALLY STOPPING. *TR

ON WEDNESDAY, FEB. 5, 2010, DRIVING A 2010 PRIUS ON A MICHIGAN ROAD AT 25 MPH, SOME ICE OR FREEZE OVER, APPROXIMATELY 9:30AM. I APPROACHED THE STOP SIGN AND THERE WAS NO BRAKE ENGAGEMENT, NO SOUND OR FEEL OF AN ANTILOCK BRAKE SYSTEM . I COULDN'T STOP THE CAR, SO I HAD TO PROCEED THRU THE STOP INTERSECTION. THERE WASN'T AN ACCIDENT SINCE THERE WASN'T A CAR CROSSING THE INTERSECTION. *TR

THERE WAS A DELAY FROM THE TIME I APPLIED THE BRAKES IN MY 2010 PRIUS WHEN DRIVING ON SLIPPERY, SNOW COVERED ROADS UNTIL I COULD FEEL THEM START TO SLOW THE CAR. THE ABS SYSTEM ALSO SEEMED TO ACT MORE SLOWLY. I ALSO DROVE MY 1998 FORD EXPLORER ON THE SAME ROADS SOON AFTER DRIVING THE PRIUS. THE EXPLORER ABS SYSTEM REACTED MORE QUICKLY AND DEFINITELY STOPPED MORE QUICKLY THAN THE PRIUS. *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

TEMPORARY BRAKE FAILURE WHEN BRAKING OVER POTHOLES OR BRAKING IN A TURN *CN

MY 2010 PRIUS STOPS BRAKING OR ACCELERATES WHEN HITTING A POTHOLE OR BUMP CAUSING THE CAR TO STOP LATER THAN ANTICIPATED. ALMOST HIT A PERSON IN THE CROSS WALK. *CN

I OWN A 2010 TOYOTA PRIUS. WHEN I APPROACH A POTHOLE OR ROUGH PATCH IN THE ROAD AND APPLY THE BRAKES AS I AM DRIVING OVER IT, THE BRAKES SLIP AND THE CAR LURCHES FORWARD. 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

WHILE DRIVING ON 2/5/10 IN SNOWY CONDITIONS AT ABOUT 15 MPH, I SLID THROUGH A STOP LIGHT IN MY 2010 PRIUS. I WAS DRIVING CAUTIOUSLY, APPLIED MY BRAKES EARLY, KNOWING THE LIGHT MIGHT CHANGE. IT CHANGED TO YELLOW AND I HAD NO BRAKES AND SLID INTO THE INTERSECTION AS THE LIGHT TURNED RED. I HAVE HAD ANTI-LOCK BRAKES IN MY LAST TWO CARS AND HAVE HAD MY ABS ENGAGE PREVIOUSLY ON MY 2010 PRIUS. DURING THIS EVENT, NO BRAKING OF ANY SORT TOOK PLACE EVEN THOUGH I HAD THE BRAKE PEDAL DEPRESSED. FORTUNATELY, I WAS NOT HIT BY OTHER CARS IN THE INTERSECTION. I HAVE NOT HAD THE PROBLEM EXAMINED YET, BUT WILL BE TAKING MY PRIUS TO THE DEALER. *CN

MOMENTARY BRAKE LOSS. 2010 PRIUS, MFG. DATE 12/09. PURCHASE DATE 2/1/10. LOW SPEED SLOWING DOWN WITH LIGHT BRAKING FOR STOP LIGHT. HAPPENED OVER A MAN HOLE COVER (I THINK). WHEN IT FELT LIKE THE BRAKES QUITE MOMENTARLY. *CN

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.

2010 TOYOTA PRIUS BRAKING PROBLEM. GOING DOWN STEEP LONG HILL, WITH ROUGH SURFACE, WE ENCOUNTER THIS PROBLEM 1 OR 2 TIMES A WEEK, REPEATEDLY. IT FEELS LIKE WE ARE "FLYING" DOWN THE HILL BRIEFLY, OUT OF CONTROL, WHILE IN FACT, WE ARE GOING APPROXIMATELY 15 MILES PER HOUR AND ARE APPLYING THE BRAKE IN THE SAME MANNER AS ALWAYS. THIS IS VERY SCARY, AS THE HILL HAS A HUGE DEEP RAVINE ON ONE SIDE, AND A HIGH CLIFF ON THE OTHER SIDE, AND A CLIFF OFF A BEACH INTO THE SALT WATER AT THE BOTTOM OF THE HILL. THE ROAD IS VERY NARROW, WITH 2 VEHICLES GOING UP AND DOWN ONLY ABLE TO PASS AT SELECTED POSITIONS, OTHERWISE, ONE LANE TRAFFIC. PLEASE DEMAND THAT TOYOTA RECALL THIS VEHICLE, AND REPLACE THE SOFTWARE THAT CONTROLS THE BRAKING SYSTEM. I UNDERSTAND FROM THE NEWS THAT THEY HAVE THIS FIX IN PLACE ON NEW CARS SINCE LAST MONTH. PLEASE RECALL THIS VEHICLE ASAP! MY VEHICLE NUMBER IS [XXX] PRODUCTION DATE 6/09. THANK YOU. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I BROUGHT MY 2010 PRIUS IN ON 2/5/10 FOR THE SERVICE WORK RELATING TO THE RECENT RECALL. ON THE WAY HOME, THE PROBLEM RECURRED; HOWEVER, THIS TIME, MY CAR SLIPPED WHILE I WAS DRIVING (BUT NOT BRAKING) ON ILLINOIS EAST OF MICHIGAN, WHERE THERE IS A METAL PLATE ON THE ROAD. PREVIOUSLY, THIS SITUATION OCCURRED ONLY WHILE BRAKING ON AN EVEN ROAD SURFACE. THIS TIME, I WAS NOT BRAKING. THE CAR DID NOT SURGE, BUT I DID FEEL MOMENTARILY LIKE I HAD LOST CONTROL OF IT. *TR

BRAKE FAILURE ON 2010 PRIUS IN SNOWY CONDITIONS. I WAS DRIVING WITH MY 11 YEAR OLD DAUGHTER GOING LESS THAN 10 MILES PER HOUR APPROACHING A BUSY INTERSECTION. THE BRAKES WOULD NOT ENGAGE AND I COULD NOT STOP BEFORE ENTERING THE INTERSECTION. I WAS ALMOST HIT BY A BUS. THE BUS SAW ME AND SPED UP THUS AVOIDING A TRAGEDY. ALSO, THE OTHER ONCOMING TRAFFIC WAS ABLE TO STOP AND AVOID ME. MY DAUGHTER AND I WERE VERY FORTUNATE. I AM HORRIFIED AND WANT THIS CORRECTED. *TR

TWO FAILURES. FIRST WHILE TRAVELING AT HIGH SPEED FROM CANADA TO NYC ON DECEMBER 26, THE LEFT SIDE OF MY ELECTRONIC DISPLAY WENT OUT, SPECIFICALLY THE SPEEDOMETER AND GAS MILEAGE COMPONENT OF THE DISPLAY BLANKED OUT. IT TOOK TOYOTA ABOUT A WEEK TO FIGURE OUT HOW TO FIX IT. SECONDLY, I BROUGHT MY 2010 PRIUS INTO MY LOCAL DEALER BECAUSE OF THE BRAKING ACCELERATION ISSUE. IT HAD HAPPENED ABOUT 10 TIMES SINCE I BOUGHT THE CAR ON JUNE 30, 2009. AS THE CAR WAS BRAKING TO A STOP, THERE SEEMED TO BE AN ACCELERATION ASSOCIATED WITH THE BRAKING. WHEN I BROUGHT IT TO STAR TOYOTA OF BAYSIDE, THEY HAD THE TECHNICIAN DRIVE THE CAR FOR ABOUT 3 MILES AND STATED THAT THEY FOUND NO TROUBLE. *TR

I BELIEVED THE PROBLEM IS IN THE BRAIN BOX OF THE 2008-2010 PRIUS/ETC IN ARE AREA WHERE THE NAVY GENERATE LOW FREQUENCY SIGNALS ARE GARAGE DOORS GO UP AND DOWN AT WILL .WE HAD NO IDEA UNTIL THE NAVY ADMITTED IT. NOW WHIT CELL TOWERS SET UP EVERY WHERE AND WHO KNOWS WHAT SIGNAL ARE GENERATED THRU THEM. WHO TO SAY THAT IT IS AT SOME POINT IT EFFECTING SOME OF THE TOYOTAS AFTER ALL THEY ARE ROLLING COMPUTERS WHEN THEY STOP THE ERRATIC BEHAVIOR AND THEN REBOOT WITHOUT A TRACE. *TR

2010 TOYOTA PRIUS III. THE CONSUMERS DAUGHTER WAS INVOLVED IN AN ACCIDENT. THE BRAKES DID NOT STOP THE VEHICLE WHEN THEY WERE APPLIED. SHE COLLIDED WITH THE VEHICLE IN FRONT OF HER, WHICH THEN HIT ANOTHER VEHICLE. *JB

I OWN A TOYOTA PRIUS 2010 PURCHASED IN THE SUMMER OF 2009. I HAVE EXPERIENCED BRAKING ISSUES UNDER CERTAIN CONDITIONS. *JB

I'VE OWNED MY 2010 TOYOTA PRIUS FOR 5 MONTHS NOW AND FREQUENTLY (AT LEAST TWICE A MONTH) EXPERIENCE PROBLEMS WHEN BRAKING ON UNEVEN GROUND. WHEN I AM HITTING THE BRAKES AND RUN OVER A POTHOLE OR SUDDEN BUMP, THE CAR STOPS SLOWING DOWN AND ALMOST SHOOTS FORWARD (FEELS LIKE I'M HYDROPLANING) FOR A SPLIT SECOND THEN RESUMES BRAKING. THIS HAPPENED MOST RECENTLY TODAY AND COULD HAVE CAUSED AN ACCIDENT IF I WERE CLOSER TO THE CAR IN FRONT OF ME WHEN IT OCCURRED. *JB

OUR 2010 PRIUS SOMETIMES LURCHES FORWARD ON HITTING A BUMP OR DRIVING ON ROUGH TERRAIN. THIS HAPPENS PREDICTABLY AT CERTAIN LOCATIONS. BOTH MY WIFE AND I HAVE OBSERVED THIS BEHAVIOR, MAYBE A COUPLE OF TIMES/WEEK. NOT CERTAIN WHETHER IT'S MOMENTARY ACCELERATION OR LOSS OF BRAKING BUT WE THINK IT'S LOSS OF BRAKING. WE HAVE NOT YET TAKEN ANY CORRECTIVE ACTION. I READ IN THE PAPER THAT TOYOTA IS PLANNING A RECALL. *JB

MY 2010 PRIUS LURCHES WHEN I GO OVER POT HOLES OR ROUGH PATCHES. I CAN CONTROL THE LURCH, BUT IT DOES NOT FEEL RIGHT. IT DOES NOT HAPPEN ALL THE TIME. I AM NOT SURE WHAT MAKES THE DIFFERENCE BETWEEN IT HAPPENING AND NOT HAPPENING. I RECEIVED THE TITLE TO THE CAR IN 8/27/09. *JB

TOYOTA PRIUS BRAKE LOSS OF CONTROL - WHEN THE VEHICLE GOES OVER A BUMP (E.G. POTHOLE, MANHOLE) WHEN THE BRAKE IS BEING APPLIED, IT DOESN'T IMMEDIATELY STOP BUT INSTEAD SEEMS TO LURCH FORWARD WITH THE SENSATION OF LOSS OF CONTROL. THIS ESPECIALLY HAPPENS ON CITY STREETS OR IN ICY CONDITIONS. IF THERE WAS A PERSON OR CAR IN FRONT OF THE VEHICLE, THE PRIUS WOULD HAVE HIT THE PERSON/CAR. THIS HAPPENS EVERY DAY AT THE SAME STOP (BUMP IN ROAD WHEN TURNING), AS WELL AS RANDOM PLACES AT LEAST WEEKLY SINCE PURCHASING THE CAR IN SEPTEMBER 2009. *JB

WHEN OUR 2010 PRIUS GOES OVER A BUMP THE BRAKES SEEM TO DISENGAGE AND SPEED FEELS LIKE IT IS INCREASING. ALTHOUHG TODAYS DATE IS ON THE EVENT THIS HAS BEEN AN ONGOING CONCERN SINCE PURCHASING THE VEHICLE LAST YEAR. *JB

I DROVE OVER A BUMP WHILE BRAKING AND IT FELT LIKE THE CAR WAS SLIDING ON ICE. IT FELT LIKE THERE WERE NO BRAKES. *TR

I HAVE A 2010 PRIUS AND HAD A 2005 PRIUS WITH ALL THE SAFETY FEATURES. WHEN I HAD THE 2005 PRIUS, I NOTICED ON SOME ROADS THAT DURING BRAKING, THE BRAKES WOULD RELEASE THEN REENGAGE, GIVING THE SENSATION THAT THE CAR IS ACCELERATING. THIS HAPPENS WHEN THE ROAD HAS A SERIES OF DIPS (WASHBOARD). THE FIRST COUPLE TIMES THIS HAPPENED, IT WAS RATHER FRIGHTENING BECAUSE THE CAR IN FRONT OF ME HAD STOPPED, AND I FELT AS IF I WERE ACCELERATING. THIS IS A REPRODUCIBLE EVENT THAT OCCURS AT A KNOWN LOCATION THAT I SIMPLY AVOID. THE ROAD IN THIS PARTICULAR AREA IS ALSO DOWN SLOPE, WHICH LENDS TO THE ACCELERATION FEELING. I HAVE DRIVEN MY 2010 PRIUS OVER THIS SAME AREA WITH VERY MUCH THE SAME RESULT. MY INITIAL ASSESSMENT WAS THAT THE TRACTION CONTROL TOOK OVER TO REGAIN TRACTION, HOWEVER I WOULD NOT THING THIS IS ACCEPTABLE. THE TOYOTA DEALERSHIP SAID THIS IS NORMAL BEHAVIOR AND IS NOT A PROBLEM. PLEASE FEEL FREE TO CONTACT ME AND I CAN DESCRIBE BETTER THE CONDITIONS FOR THIS VERY REPRODUCIBLE EVENT. *TR

PRIUS 2010 SLOW BRAKING. I THOUGHT IT WAS JUST ME BUT NOW I FOUND OUT THE BRAKING IS RATHER SLOW AND A LOT OF OTHERS FEEL THE SAME WAY. I HAVE TO ADJUST MY BRAKING WHEN I SWITCH CARS WITH MY WIFE AND HAVE TO EXTRA CAREFUL WHEN I SWITCH BACK TO PRIUS. *TR

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

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

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

BRAKE FAILURE - AS I DRIVE TO WORK EACH DAY THERE IS A PLACE WHERE I AM TURNING ONTO A DIFFERENT ROAD TO GET TO WORK. AS I APPROACH THE TURN I BRAKE TO SLOW DOWN AND I ALWAYS HIT A BUMP IN THE ROAD AND/OR A POTHOLE CLOSE TO THE INTERSECTION. AS I HIT THE AREA, MY CAR SHOOTS FORWARD AND IT FEELS LIKE I HAVE LOST MY BRAKES. I CAN RECOVER QUICKLY BY KEEPING MY FOOT ON THE BRAKE, BUT IF I WAS CLOSER TO THE INTERSECTION I COULD OVERSHOOT IT AND HIT SOMEONE OR SOMEONE COULD HIT ME. I MENTIONED IT TO THE SERVICE MANAGER WHEN I GOT MY FIRST OIL CHANGE AT 5000 MILES AND HE SEEMED VERY UNCONCERNED AND HE SAID IT WAS PROBABLY THE ABS BRAKES FAILING BECAUSE THE TIRE LOST CONTACT WITH THE ROAD. WELL I ALSO HAVE A 2002 HIGHLANDER AND HAVE NEVER HAD THE PROBLEM WITH THIS CAR. *TR

MY 2010 TOYOTA PRIUS BRAKE PROBLEM: TO BEGIN DRIVING MY PRIUS FROM A STOPPED POSITION ONE RELEASES THE BRAKE PEDAL BEFORE PRESSING THE ACCELERATOR PEDAL. QUITE OFTEN WHEN ATTEMPTING TO RELEASE THE BRAKE PEDAL ON MY PRIUS THERE WILL BE AN INSTANT JERK AND ANY VEHICLE MOVEMENT APPEARS TO BE DEAD LOCKED. AFTER SEVERAL ATTEMPTS IT WILL THEN APPEAR TO STRAIGHTEN OUT AND THEN DRIVING IS OK. CONSIDERING MY DRIVING HABITS, THIS IS VERY MUCH A SAFETY PROBLEM FOR ME, AND ALSO I DON'T TRUST THE CAR. *TR

LIKE MANY OTHERS, I TOO HAVE EXPERIENCED THE BRAKE PROBLEM WITH THE 2010 PRIUS. WHEN GOING OVER A POTHOLE (WHILE USING THE BRAKE), THE BRAKE FAILS MOMENTARILY AND THE CAR LURCHES FORWARD. *TR

DESIGN FLAW ON A BRAND NEW 2010 TOYOTA PRIUS THAT MAKES RATTLING NOISE NEAR THE GEAR SHIFT LEVER THAT COULD BRAKE THE GEAR LEVER. *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

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

MY CURRENT 2010 PRIUS HAS THE "JUMP" ISSUE WITH THE BRAKES, BUT THIS IS NOT THE FIRST TIME THAT THIS HAS HAPPENED WITH THE PRIUS. MY 2002 PRIUS HAD THE SAME ISSUE, AND I WAS NOT THE ONLY ONE. I WAS A MEMBER OF A PRIUS YAHOO GROUP, AND THIS WAS A TOPIC OF DISCUSSION FOR A WHILE. SO WHILE I DO FEEL THE "JUMP" I JUST THOUGHT IT WAS PART OF THE PRIUS EXPERIENCE. WHENEVER I DRIVE OVER A POTHOLE, IT FEELS LIKE THE CAR IS TRYING TO JUMP IT. WHEN HITTING THE BRAKES, IT FEELS LIKE THERE IS ACCELERATION FOR JUST A SECOND. THIS IS NOT AN INTERMITTENT PROBLEM. IT HAPPENS EVERY TIME. *TR

WHEN SLOWING TO A RED LIGHT ON MD 212 AT US RT 1 IN BELTSVILLE, MD, MY 2010 TOYOTA PRIUS ROLLED OVER A BUMPY STRETCH OF ROAD AND THE REGENERATIVE BRAKES STOPPED BRAKING. THE CAR ROLLED FORWARD IN "FREE WHEEL" FASHION UNTIL I STOMPED ON THE BRAKES HARD AT WHICH POINT THE FRICTION BRAKES KICKED IN AND STOPPED THE VEHICLE IN TIME TO AVOID AN ACCIDENT WITH THE VEHICLE IN FRONT OF ME. THE TRACTION CONTROL INDICATOR LAMP LIT, AND REMAINED LIT UNTIL I RELEASED THE BRAKES TO ACCELERATE WHEN THE LIGHT TURNED GREEN. SEEMS TO BE THE SAME PROBLEM EVERYONE IS REPORTING IN THE NEWS THIS MORNING. I'VE HAD THE CAR 1.5 WEEKS, AND THIS IS THE FIRST TIME I'VE NOTICED THE PROBLEM, ALTHOUGH MY WIFE CLAIMS IT HAPPENED TO HER DURING OUR TEST DRIVE. *TR

I HAVE EXPERIENCED MULTIPLE INCIDENTS OF LOSS OF BRAKING CONTROL IN MY 2010 PRIUS. TODAY I WENT TO PUT ON MY BRAKES AND THE SYSTEM LOCKED UP ON ME AND THEN, LUCKILY, RELEASED AND I REGAINED CONTROL OF MY BRAKES BEFORE HITTING THE CAR IN FRONT OF ME. *TR

I HAVE A 2010 PRIUS AND WOULD LIKE TO LOG A COMPLAINT THAT I TOO AM EXPERIENCING THE LAG EFFECT ON THE BRAKING SYSTEM. I READ TODAY THAT IT COULD BE A COMPUTER SOFTWARE PROBLEM. PLEASE LOG THIS COMPLAINT SO THE REAL MAGNITUDE OF THIS PROBLEM IS TALLIED. *TR

2010 PRIUS BRAKING ISSUE. I HAVE FELT THE LOSS OF BRAKING WHILE GOING OVER POTHOLES ATLEAST 4 TIMES SINCE I HAVE OWNED MY 2010 PRIUS SINCE LAST YEAR. *TR

I PURCHASED A 2010 TOYOTA PRIUS IN DECEMBER 2009. I LIVE IN DULUTH MINNESOTA WHERE THE STREETS ARE HILLY, BUMPY, AND OFTEN ICY. AT LEAST TWICE A DAY, AS I'M COMING DOWN A HILL TOWARD A STOP SIGN AND APPLY THE BRAKES, I NOTICE THE BRAKES SEEM TO GIVE OUT (I.E., CEASE TO FUNCTION) FOR A BRIEF INTERVAL, PERHAPS A SECOND OR TWO. DURING THIS BRIEF INTERVAL, THE CAR SEEMS TO SURGE FORWARD. I REPORTED THIS TO THE DEALER THIS MORNING AND THEY SAID NO FIX IS YET AVAILABLE. *TR

BRAKING POWER MOMENTARILY STOPS WHEN HITTING A BUMPY SURFACE SUCH AS POT HOLE OR UNEVEN ROAD SURFACE. EVEN PRESSURE CAUSES MOMENTARY LOSS OF BRAKING POWER BUT POWER RETURNS AFTER A SECOND AND BRAKING RESUMES. *TR

2010 TOYOTA PRIUS MODEL III. DURING LIGHT BRAKING, WHEN THE VEHICLE IS USING THE REGENERATIVE BRAKES, RATHER THAN THE MECHANICAL FRICTION BRAKES, IF A POTHOLE OR RAILROAD TRACK IS CROSSED, THE BRAKES FEEL LIKE THEY SLIP A BIT BEFORE THEY CATCH AGAIN. THE CAR DOES NOT ACCELERATE, BUT THE DECELERATION FROM BRAKING DOES DECREASE FOR PART OF A SECOND. THIS HAS HAPPENED TO ME SEVERAL TIMES IN THE PAST 6 MONTHS AND IS REPEATABLE. *TR

I WAS APPROACHING A TRAFFIC SIGNAL, HIT A SMALL POT HOLE, AND APPLIED THE BRAKES ON MY 2010 TOYOTA PRIUS. THE PEDAL WENT ALL THE WAY TO THE FLOOR AND THE CAR DID NOT SLOW. I RELEASED THE PEDAL AND STEPPED ON IT A SECOND TIME AND THIS TIME THE BRAKES WORKED. *TR
