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

SERVICE BRAKES, HYDRAULIC
WHILE BRAKING MY 2010 PRIUS THERE ARE TIMES WHERE THE CAR APPEARS TO SURGE FORWARD. THE INITIAL BRAKING OCCURS FINE BUT NEAR THE POINT OF COMING TO A COMPLETE STOP (IE LESS THAN 10MPH) IS WHEN THE SURGE OCCURS. INITIALLY I ATTRIBUTED THIS TO ICY ROAD CONDITIONS BUT THIS HAS NOW OCCURRED ON DRY PAVEMENT. THE DASH LIGHT INDICATING SLIPPAGE OF THE CAR DOES NOT APPEAR WHEN THIS OCCURS. THE PROBLEMS SEEMS TO OCCUR MORE OFTEN WITHIN THE FIRST 5 MILES OF STARTING THE CAR. THIS SURGE DOES NOT OCCUR EVERYDAY NOR EVERY TIME THE CAR IS STARTED. IT DOES NOT SEEM TO BE STRICTLY TEMPERATURE RELATED ALTHOUGH IT HAS STARTED OCCURRING ONLY IN THE WINTER (CAR PURCHASED IN JULY). *TR

SERVICE BRAKES, HYDRAULIC
WHEN BRAKING OUR 2010 TOYOTA PRIUS, THE BRAKES SOMETIMES RELEASE WHILE THE DRIVER'S FOOT IS ON THE BRAKE PEDAL. THE DRIVER NEEDS TO RELEASE THE BRAKE PEDAL AND RE-APPLY PRESSURE FOR THE BRAKE TO RE-ENGAGE. THE PROBLEM DOES NOT OCCUR EVERY DAY BUT IT HAS OCCURRED OFTEN ENOUGH THAT BOTH DRIVERS OF OUR CAR HAVE NOTICED THIS ON SEVERAL OCCASIONS DURING THE SIX MONTHS THAT WE HAVE OWNED THE CAR. IT APPEARS TO OCCUR MORE AT SPEEDS BELOW 15 MPH, ON DOWNHILL SLOPES, IN COLDER WEATHER AND ON SLIPPERY ROADS. GIVEN THE CIRCUMSTANCES, THE PROBLEM TENDS TO HAPPEN WHEN APPROACHING INTERSECTIONS, WHERE MOST BRAKING TAKES PLACE, MAKING IT A MORE DANGEROUS DEFECT. WE PURCHASED THE CAR AT THE END OF JULY, 2009. WE REPORTED THE PROBLEM TO THE TOYOTA DEALERSHIP WHEN THE CAR WAS IN FOR ITS FIRST 5000 MILE SERVICE IN JANUARY, 2010. THEY ROAD-TESTED THE CAR BUT COULD NOT REPLICATE OUR EXPERIENCE, SO THEY COULD NOT DIAGNOSE THE ISSUE. *TR

SERVICE BRAKES, HYDRAULIC
MY 2010 TOYOTA PRIUS UNDER CERTAIN CONDITIONS WILL HAVE A REDUCTION IN BRAKING POWER. IT WILL GIVE THE ILLUSION OF ACCELERATION, BUT I BELIEVE THE PROBLEM IS A REDUCTION IN BRAKING POWER. THIS PROBLEM HAS HAPPENED REPEATEDLY AND I FREQUENTLY EXPERIENCE IT IN A LOCATION I REGULARLY DRIVE. AS I APPROACH A 4-WAY STOP THERE IS A BUMP THAT COVERS THE WIDTH OF MY LANE. AS THE FRONT TIRES GO OVER THE BUMP THE CAR FEELS LIKE IT START TO TAKE OFF JUST SHORT OF THE STOPPING POINT. IT QUICKLY RECOVERS AND I AM ALWAYS ABLE TO STOP, BUT THE FEELINGS IS UNNERVING SINCE IT HAPPENS SO CLOSE TO THE STOPPING POINT. I HAVE CONTACTED MY TOYOTA DEALER, BUT THEY SAY THEY HAVE NO REPORTED PROBLEMS AND DID NOT EVEN TAKE ANY INFORMATION. *TR

2010 TOYOTA PRIUS - WHEN BRAKING, IF YOU HIT A BUMP OR POT HOLE IN THE ROAD, THE CAR LUNGES FORWARD (ACCELERATES). YOU HAVE TO REALLY PAY ATTENTION FOR THIS OCCURRENCE OR YOU WILL REAR END SOMEONE. I HAS HAPPEN ABOUT 5 TIMES NOW. THIS SEEMS TO BE A ELECTRONICS ISSUE NOT A PEDAL PROBLEM. *TR

SERVICE BRAKES, ELECTRIC
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

SERVICE BRAKES, HYDRAULIC
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 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

SERVICE BRAKES, HYDRAULIC
2010 TOYOTA PRIUS HAS A MAJOR FLAW IN THE REGENERATIVE / HYDRAULIC BRAKING SYSTEM. IF THE CAR IS SLOWING GRADUALLY WITH REGENERATIVE BRAKING ACTIVE AND THE ROAD SURFACE CHANGES DUE TO A POTHOLE, UNEVEN/BROKEN SURFACE, OR SPEED BUMP, THE HYDRAULIC BRAKING IS REENGAGED VERY SLOWLY. THIS CAUSES THE CAR TO APPEAR TO ACCELERATE FOR A SECOND OR TWO UNTIL HYDRAULIC BRAKING IS ENGAGED BY THE CAR'S COMPUTER OR BECAUSE THE DRIVER HAD TO INCREASE BRAKE PEDAL PRESSURE DRAMATICALLY TO SLOW/STOP THE CAR. I HAVE BEEN ABLE TO REPRODUCE THIS DAILY ON A NUMBER OF THE ROADS I CONSISTENTLY TRAVEL. SPEED DURING THESE INCIDENTS IS USUALLY ANYWHERE BETWEEN 5 AND 30 MPH. ONE EXAMPLE: DRIVING ON A ROAD AND COMING TO A STOP LIGHT... SLOWING GRADUALLY ON REGEN BRAKING, THEN I HIT A PART OF THE ROAD WHERE THERE IS AN UNEVEN SURFACE. REGEN BRAKING STOPS AND CAR COASTS WITH NO BRAKING, SOMETIMES FOR UP TO A SECOND OR TWO. THIS IS A MAJOR CONCERN AS IT COULD RESULT IN A CAR ACCIDENT OR PEDESTRIAN DEATH. I HAVE ALREADY HAD AT LEAST TWO NEAR MISSES WHERE I HAVE HAD TO SLOW OR STOP SUDDENLY WHILE BRAKING IN REGEN MODE AND THE SWITCH TO HYDRAULIC MODE IS SEVERELY DELAYED. THIS COULD HAVE RESULTED IN REAR-ENDING A CAR IN FRONT OF ME. ISSUE HAS BEEN OBSERVED SINCE I FIRST OBTAINED THE CAR IN JULY 2009. *TR

SERVICE BRAKES, HYDRAULIC
MULTIPLE EVENTS/FAILURES, HERE IS A SUMMARY: 1) WHILE BRAKING OVER ROUGHER ROAD CONDITIONS -- NOT POTHOLES, BUT REGULAR ROUGHNESS/BUMPS IN ROADS -- BRAKES FEEL LIKE THEY MOMENTARILY NO LONGER FUNCTION/GO OUT. AS SOON AS YOU RETURN TO SMOOTH ROAD SURFACES, THE PROBLEM CORRECTS ITSELF. THIS HAS OCCURRED ON NUMEROUS OCCASIONS, THE DEALERSHIP WITH WHOM I PURCHASED MY VEHICLE WERE UNAWARE OF THE PROBLEM WHEN I CALLED THEM, EVEN THOUGHT IT HAS BEEN DISCUSSED IN THE NATIONAL NEWS. 2) BRAKE MALFUNCTION ON SLIPPERY ROADS. I WAS DRIVING TO WORK AND GOING VERY SLOW, LEAVING MORE THAN ENOUGH SPACE TO STOP FROM THE CAR IN FRONT OF ME. I APPROACHED A RED LIGHT AND LIGHTLY APPLIED THE BRAKES. HAVING PLENTY OF SPACE TO STOP, I REALIZED THAT MY CAR WAS NOT SLOWING AS IT SHOULD. REGARDLESS OF THE PRESSURE APPLIED THERE WAS NO CHANGE. I ENDED UP STOPPING BY REARENDING THE VEHICLE IN FRONT OF ME. THE DAMAGE WAS MINIMAL, BUT SCARY NONETHELESS. *TR

I PURCHASED A TOYOTA PRIUS 2010 IN OCTOBER LAST YEAR. I HAVE HAD ONE BRAKING FAILURE INCIDENT WHEN THE CAR FAILED TO BRAKE AS I WAS APPROACHING A STOP STREET. THE BRAKES DID NOT RESPOND AND THEN A FEW SECONDS LATER KICKED IN AND THE CAR CAME TO A SLOW STOP. I HAVE ALSO EXPERIENCED ABOUT 6 INCIDENTS WHERE MY CAR ACCELERATED WHILE MY FOOT WAS ON THE BRAKE. THESE INCIDENTS OCCURRED WHEN I TRAVELED OVER A BUMP OR VARIANCE IN THE ROAD. I HAVE SCHEDULED A SERVICE SO THAT TOYOTA CAN REVIEW THE BRAKING SYSTEM IN MY CAR. *TR

WHILE INITIATING BRAKING AT SPEEDS <30MPH, THE BRAKES WILL INFREQUENTLY, BUT OCCASIONALLY ENGAGE W/ NORMAL FORCE BEFORE THE BRAKES LOSE NORMAL BRAKING FORCE FOR A SPLIT SECOND BEFORE RE-ENGAGING (ESPECIALLY IF BRAKE PEDAL IS DEPRESSED FURTHER). FEELS LIKE AN ISSUE W/ ENGAGING REGENERATIVE BRAKES. NOT EASILY REPLICABLE, HAS HAPPENED GOING DOWNHILL AND WHILE HITTING A SMALL POTHOLE 2-3 TIMES IN LAST FEW MONTHS (VEHICLE PURCHASED NOV '09). *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

WE OWN A 2010 PRIUS AND SEVERAL TIMES SINCE WE PURCHASED IT IN NOVEMBER 2009 WE HAVE NOTICED ISSUES WITH THE BRAKING SYSTEM. ON EACH OCCASION WE WERE DRIVING OVER AN UNEVEN OR SLIPPERY SURFACE (E.G., POTHOLES, ICY MANHOLE COVERS) AND WHEN THE BRAKE WAS PRESSED IT DIDN'T IMMEDIATELY ENGAGE OR CATCH. RATHER, THE BRAKES ENGAGED AFTER THE CAR PASSED THE SLIPPERY OR BUMPY SURFACE. THE PROBLEM SEEMS TO RESULT IN AN ACCELERATION (OR PERHAPS SLOWER DECELERATION) WHEN ONE STEPS ON THE BRAKE PEDAL. ON AT LEAST ONE OCCASION, AN INDICATOR LIGHT ON THE DASH DISPLAY LIT UP. *TR
