2010 Toyota Prius complaints

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

THIS IS THE 3RD TIME I HAVE HAD A TOTAL LOCKOUT OF BRAKING ON MY 2010 TOYOTA PRIUS. THIS SEEMS TO HAPPEN MOST TIMES IF THE ROAD IS SLIGHTLY ROUGH AND DOWNHILL. DEALER DENIES ANY KNOWN PROBLEMS BUT THIS LAST TIME I WENT COMPLETELY THROUGH A STOP SIGN. HAD THERE BEEN OTHER TRAFFIC I WOULD HAVE HAD AN ACCIDENT. *TR

MY 2010 TOYOTA PRIUS, HAS ON AT LEAST FIVE OCCASIONS, SURGED FORWARD WHEN I HIT THE BRAKES, ESPECIALLY COMING OFF OF CRUISE CONTROL HEADING TO A HIGHWAY OFF RAMP. THESE HAVE OCCURRED BETWEEN SEPTEMBER 1 AND THE PRESENT, FEBRUARY 2. THE CAR SURGES FORWARD EVEN THOUGH I AM NOT ACCELERATING AND HAVE IN FACT HIT THE BRAKES. I THEN HIT THE BRAKES HARDER AND THE CAR HAS SLOWED. *TR

I AM WRITING ABOUT MY 2010 TOYOTA PRIUS. I HAVE NOTICED FAULTY BRAKES ON THE VEHICLE, MAINLY WHEN I AM ATTEMPTING TO BRAKE ON SLIPPERY OR BUMPY SURFACES. I LIVE IN CHICAGO WHERE THERE ARE MANY BUMPY ROADS AND POTHOLES, SO WHEN I'M COMING UP TO A RED LIGHT AND NEED TO STOP OVER A BUMPY SURFACE, IT FEELS LIKE THE BRAKES ARE LOCKING AND THAT I WILL SLIDE INTO THE CAR IN FRONT OF ME. BY PUMPING THE BRAKES, THE CAR WILL STOP, BUT IT IS A FRIGHTENING FEELING THAT I DON'T HAVE CONTROL OVER MY CAR. THE SAME THING HAPPENS WHEN IT IS RAINY OR THE ROADS ARE SLICK. THIS HAS BEEN A CONTINUAL PROBLEM SINCE I PURCHASED THE CAR IN AUGUST 2009, IN FACT I TOOK THE CAR BACK TO THE DEALER A FEW MOTHS LATER TO HAVE IT CHECKED OUT. THEY CLAIMED THAT SINCE I HAVE NOT DRIVEN A HYBRID CAR IN THE PAST THAT I WAS UNFAMILIAR WITH ITS BRAKING SYSTEM, AND THIS WAS HOW A HYBRID'S BRAKES WORKED. I DID NOT ACCEPT THAT ANSWER, BUT WHAT ELSE CAN I DO? I DO NOT WANT THEM TO REALIZE THERE IS A PROBLEM ONLY AFTER A CRASH HAS OCCURRED. *TR

BOUGHT 2010 PRIUS IN JUNE. HAVE CONTINUING BRAKE ISSUE WHEN GO OVER BUMP, CAR LURCHES FORWARD. CONTINUING PROBLEM. BELOW WHERE SAYS INCIDENT DATE PUT IN ABOUT WHEN FIRST NOTICED IT. *TR

2010 TOYOTA PRIUS - OWNED CAR FOR 8 MONTHS. FIVE TIMES CAR HAS ACCELERATED WHILE I AM PRESSING ON THE BRAKE. HAPPENS WHEN I AM SLOWING DOWN AND HIT A POT HOLE OR BUMP. VERY SCARY! HAVE A TEEN WHO IS LEARNING TO DRIVE AND SHE IS NOT ALLOWED TO USE THE PRIUS. MECHANICS AT DEALERSHIP LOOKED AT ME LIKE I WAS CRAZY. SAID THEY WOULD HAVE TO EXACTLY RE-CREATE PROBLEM TO INVESTIGATE. *TR

WHEN APPLYING BRAKES ON MY PRIUS 2010 WHILE APPROACHING A STOP SIGN OR LIGHT, IF I HIT A BUMP, THE BRAKES WILL BRIEFLY DISENGAGE. THIS HAS HAPPENED ON NUMEROUS OCCASIONS SINCE I PURCHASED THE VEHICLE LAST SUMMER. *TR

I HAVE A 2010 TOYOTA PRIUS (PURCHASED JUNE 2009). THE BRAKE SYSTEM ROUTINELY FAILS FOR 1-2 SECONDS IF I AM BRAKING AS I HIT A POTHOLE OR BUMP IN THE ROAD. IT FEELS AS IF BRAKING STARTS, THEN TOTALLY DISAPPEARS FOR 1-2 SECONDS, THEN I FEEL THE ABS SYSTEM KICK IN AFTER THAT. THIS HAS PROBABLY OCCURRED ON THE AVERAGE OF ONCE PER WEEK SINCE I HAVE OWNED MY CAR. IT OCCURS IN ROUTINE CITY DRIVING. *TR

I HAVE A 3RD GENERATION 2010 PRIUS. WHEN BRAKING, MY CAR LURCHES FORWARD WITH BRIEF SPURTS OF ACCELERATION IF I HIT A BUMP. THE BUMP OR POTHOLE DOES NOT HAVE TO BE VERY BIG AND THE LOSS OF BRAKING POWER IS FOR A SECOND OR TWO. I DO NOT BELIEVE THIS HAS ANYTHING TO DO WITH THE GAS PEDAL. *TR

OFTEN WHEN I DRIVE MY 2010 TOYOTA PRIUS OVER A MANHOLE, METAL GRATE, OR OTHER SLIPPERY SURFACE IT FEELS LIKE THE BRAKES MOMENTARILY STOP WORKING. THIS HAS HAPPENED ON SEVERAL OCCASIONS. *TR

1. 2010 PRIUS, BRAKES RELEASE AND CAR SURGES FORWARD IF ONE TIRE HITS A BUMP, POTHOLE OR UNEVEN SURFACE 2. THIS BRAKE FAILURE AND SURGING OCCURS DAILY IN BOTH DIRECTIONS ON MY COMMUTE. IN TWO LOCATIONS THE UNEVEN ROAD SURFACE FALL DIRECTLY BEFORE AN INTERSECTION AND I HAVE A DIFFICULT TIME STOPPING FOR A RED LIGHT OR NEARLY HITTING CAR IN FRONT OF ME. THIS HAS BEEN THE CASE SINCE I BOUGHT THE VEHICLE. 3. ALTHOUGH IT CONSTANTLY SCARES ME AND SEEMS ODD, I HAVE JUST TURNED 5000 MILES ON THE 2010 PRIUS AND HAVE NOT YET HAD IT FOR SERVICE AT THE DEALER. NO PARTS HAVE BEEN ALTERED OR REPLACED. I HAVE OFTEN COMPLAINED ABOUT IT AT HOME OR TO FRIENDS, BUT IT DIDN'T OCCUR TO ME TO REPORT IT. I HAVE NOT YET HAD AN ACCIDENT AS A RESULT OF THE PROBLEM. *TR

2010 PRIUS BRAKING PROBLEM. CAR FEELS LIKE IT IS JUMPING FORWARD WHILE APPLYING THE BRAKES AND TRAVELING OVER BUMPY ROADS OR POTHOLES. PURCHASED CAR IN OCTOBER 2009 AND THIS HAS OCCURRED MORE THAN 10 TIMES. *TR

2010 BRAND NEW PRIUS LURCHES FORWARD OCCASIONALLY WHEN BRAKES ARE APPLIED WHEN TURNING SHARP OR GOING OVER A BUMP. *TR

WHEN BRAKING TO COME TO A STOP, THE VEHICLE SUDDENLY ACCELERATES FORWARD OR THE BRAKES FAIL FOR JUST A MOMENT. THIS USUALLY HAPPENS WHEN THE ROAD SURFACE IS UNEVEN, OR IF THERE IS A POTHOLE. IT IS NOT REPRODUCIBLE, BUT HAS CONSISTENTLY HAPPENED ABOUT ONCE OR TWICE A MONTH SINCE I PURCHASED THE NEW VEHICLE IN NOVEMBER, 2009. *TR

THREE TIMES WHEN BRAKING WITH MY 2010 PRIUS I HAVE MOMENTARILY LOST BRAKING POWER AFTER HITTING A POT HOLE OR A BUMP. THE CAR ENDED UP STOPPING SLIGHTLY PAST WHERE I HAD INTENDED TO BRAKE. *TR

EVENT OCCURS AT SLOW SPEEDS WHEN COMING TO A STOP ON AN ICY SURFACE. INITIALLY BRAKES FEEL LIKE THEY ARE WORKING PROPERLY. THEN THE BRAKES APPEAR TO STOP WORKING FOR SPLIT SECOND. THERE IS A SENSE THAT THE CAR IS ACCELERATING, BUT I BELIEVE THE SENSATION IS CAUSED BY THE BRAKES NOT WORKING. AFTER A SPLIT SECOND THE BRAKES APPEAR TO WORK PROPERLY AGAIN. HAS ONLY OCCURRED AT LOW SPEEDS ON AN ICY SURFACE. THE CONCERN IS THAT THE REQUIRED STOPPING DISTANCE IS EXTENDED BEYOND EXPECTATIONS. THIS HAS OCCURRED ABOUT 10 TIMES THIS WINTER. AFTER THE FIRST INCIDENT, I THOUGHT THE CAR WAS SLIDING ON THE ICE. HOWEVER AFTER REPEATED OCCURRENCES, THE SENSATION IS NOT SLIDING. THE SENSATION IS THAT THE BRAKES HAVE STOPPED WORKING FOR A SPLIT SECOND. *TR

I HAVE BEEN DRIVING MY 2010 PRIUS FOR 3 MONTHS AND HAVE EXPERIENCED THE FOLLOWING ISSUES, WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND AND THE TRACTION LIGHT BLINKS. EVEN WHEN THERE ARE NO BUMPS, THERE IS A LAG IN THE TIME I DEPRESS THE BRAKE PEDAL, AND WHEN THE BRAKES ACTIVATE. THE CAR ALMOST COASTS FOR ABOUT 1-2 SECONDS, WHICH CAN MAKE THE DIFFERENCE IN AN ACCIDENT OR NOT. *TR

DRIVING NORMALLY ON A ROUGH ROAD I CAME TO AN INTERSECTION WHERE I HAD TO APPLY THE BRAKES. IN THIS INSTANCE I APPLIED THE BRAKES AND THE VEHICLE STARTED TO SLOW AS NORMAL. I THEN HIT A ROUGH PATCH OF ROAD AND THE BRAKES APPEARED TO HAVE FAILED. THERE WAS NO BRAKING POWER AT ALL. I THEN REAPPLIED THE BRAKES AND THE VEHICLE STARTED TO SLOW AS NORMAL AND THE VEHICLE THEN STOPPED. FOR THE PERIOD WHERE THERE WAS NO BRAKES IT WAS SCARY. *TR

WHEN BRAKING AND HITTING A BUMP AT THE SAME TIME THERE IS A LOSS OF BRAKING POWER. THE VEHICLE LUNGES FORWARD AS IF THE BRAKES HAVE STOPPED WORKING MOMENTARILY. THIS CAUSED ME TO HAVE TO USE ADDITIONAL CRASH AVOIDANCE MANEUVERS, IN ANOTHER CIRCUMSTANCE COULD HAVE CAUSED AN ACCIDENT. IT FEELS AS IF A PORTION OF THE BRAKING SYSTEM SHUTS OFF AFTER HITTING THE BUMP. *TR

1. GOING SLIGHTLY DOWNHILL, ONE OF THE FRONT TIRE WENT OVER A POTHOLE, ON OTHER OCCASIONS, GOING OVER A SLIGHTLY BUMPY WET ROAD 2. TEMPORARY (ABOUT 2-4 SECONDS) BRAKE LOSS, HAS OCCURRED ABOUT 3-5 TIMES IN 3 MONTHS 3. NOTHING DONE SO FAR, WAITING TO VISIT DEALER AT 5000 MILES OR FOR TOYOTA TO ISSUE SOME KIND OF RECALL. *TR

2010 TOYOTA PRIUS - WHILE BRAKING CAR HAS OCCASIONALLY LUNGED FORWARD - SEEMINGLY WHEN HITTING AN UNEVEN SECTION OF ROAD. FEELS AS IF CAR SUDDENLY HIT A PATCH OF ICE -NONE PRESENT OF COURSE. MORE NOTICEABLE WHEN TURNING. THIS HAS HAPPENED APPROXIMATELY 6 DIFFERENT TIMES. *TR

I HAVE DRIVEN MY 2010 PRIUS FOR ABOUT 8 MONTHS. WITH THE BRAKE APPLIED AND SLOWING THE CAR, THE BRAKE RELEASES AND THE CAR LURCHES FORWARD WHEN I HIT A BUMP IN THE ROAD. FORTUNATELY, I WAS ALWAYS ABLE TO REGAIN CONTROL OF THE VEHICLE PRIOR TO AN ACCIDENT. THIS EVENT HAS HAPPENED ABOUT 5 TO 10 TIMES IN THE 8 MONTHS AND SEEMS TO OCCUR AT SLOWER SPEEDS LIKE APPROACHING A STOP SIGN OR STOP LIGHT. *TR

BRAKE PROBLEMS: MY 2010 PRIUS, WHICH I PURCHASED LAST OCTOBER, HAS BEEN HAVING SPORADIC PROBLEMS WITH THE BRAKES. IT USUALLY OCCURS ON THE STREETS, AND AT LOW SPEEDS, AND THE CAR SEEMS TO LUNGE FORWARD EVEN THOUGH I HAVE MY FOOT ON THE BRAKES. IT'S AS IF I STOPPED BRAKING EVEN IN FACT, I'VE BEEN PUTTING UNIFORM PRESSURE ON THE BRAKES. THANKFULLY, THIS HAS NOT CAUSED ANY INJURIES OR ACCIDENTS, BUT I AM CONCERNED ABOUT THE PROBLEM. *TR

I HAVE A 2010 PRIUS AND WHEN I DROVE OVER A BUMP OR POT HOLE MY CAR FAILS TO ACCELERATE FORWARD AND LOSE ANY BRAKING FEELING (ALMOST TO WHERE I LOSE CONTROL OF THE CAR). IT HAPPENS ONLY FOR A SHORT MOMENT. *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 ATTEMPTING TO BRAKE AT A STOP SIGN AS I WAS MOVING SLOWLY UP AN INCLINE IN A RESIDENTIAL NEIGHBORHOOD, MY 2010 PRIUS HYBRID SEEMED TO LURCH FORWARD. THIS HAS ONLY HAPPENED ONCE IN THE THREE MONTHS SINCE I PURCHASED THE VEHICLE, BUT IT STARTLED ME. THANK GOODNESS THERE WAS EXTRA DISTANCE BETWEEN MY CAR AND THE VEHICLE IN FRONT OF ME, OR THERE COULD HAVE BEEN A FENDER BENDER. *TR

I SAW AN ARTICLE ABOUT THE 2010 PRIUS LUNGING WHEN HITTING A BUMP OR POTHOLE. I OWN ONE AND HAVE HAD THE EXPERIENCE ON MORE THAN 1 OCCASION. *TR

ON MY WAY TO WORK THERE IS A ROUGH PATCH OF PAVEMENT WHERE I HAVE TO SLOW DOWN BEFORE A TURN AND A STOP. IF I AM APPLYING THE BRAKES WHEN I HIT IT, THE CAR WILL SURGE FORWARD, FEELING OUT OF CONTROL LIKE ON ICE, UNTIL THE CAR IS ON SMOOTH PAVEMENT AGAIN. FORTUNATELY THERE WASN'T A VEHICLE IN FRONT OF ME THE FIRST TIME IT HAPPENED, AND FROM THEN ON, I SLOW DOWN WELL BEFORE THE ROUGH PATCH, AND DON'T APPLY MY BRAKES ON THE PATCH, OR SIMILAR PATCHES. *TR

I EXPERIENCE DIFFICULTY WITH THE BRAKES OF MY 2010 PRIUS. SOMETIMES THE BREAKS DO NOT TAKE HOLD WHEN I PRESS THE BRAKE PEDAL AND THE CAR SEEMS TO SKIP FORWARD FOR A SECOND OR TWO BEFORE IT BEGINS TO SLOW DOWN AND THE BRAKES TAKE HOLD. IT IS VERY UNSETTLING BUT I HAVE NOT HAD AN ACCIDENT. MY WIFE WILL NOT DRIVE THE CAR. I REPORTED IT TO THE SERVICE MANAGER AT MY DEALER, SEEGER TOYOTA IN ST. LOUIS COUNTY, MISSOURI. HE SAID HE KNEW OF NO COMPLAINTS LIKE THIS WHATSOEVER. THEN HE CALLED ME BACK AND SAID TOYOTA WAS INVESTIGATING A BRAKE ISSUE WITH THE 2010 PRIUS THAT ONLY OCCURRED ON ROUGH SURFACES AND WAS NOT APPLICABLE TO THE PROBLEM I DESCRIBED THAT HAPPENS ON SMOOTH SURFACES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT WAS ATTEMPTING TO STOP THE VEHICLE WHILE TRAVELING AT A LOW SPEED OVER A BUMP THE CONTACT NOTICED THAT THE VEHICLES BRAKES WOULD SUDDENLY RELEASE FOR A SHORT MOMENT AND THEN WORKS PROPERLY. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALERSHIP AND THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 11000. THE CONSUMER STATED HE TOOK THE VEHICLE TO THE SERVICE DEALER TO HAVE THE RECALL PERFORMED ON THE BRAKES, HOWEVER THE VEHICLE CONTINUES TO EXHIBIT THE SAME PROBLEM. WHEN BRAKING, THE THEY SEEM TO RELEASE. UPDATED 06/15/10.*JB

2010 TOYOTA PRIUS- CAR TENDS TO ACCELERATE AFTER HITTING SOME POTHOLES OR BUMPS IN THE ROAD WHEN THE BRAKE IS DEPRESSED. THE FIRST COUPLE OF TIMES, I CAME VERY CLOSE TO REAR-ENDING THE CAR IN FRONT OF ME BECAUSE THE BUMP OR POTHOLE WAS IN THE ROAD AT A TRAFFIC LIGHT AND I WAS ATTEMPTING TO STOP. I HAVE BEEN ABLE TO REPEAT INCIDENT BUT NOT ALL OF THE TIME (MAY DEPEND ON HOW HARD THE BRAKE IS DEPRESSED OR HOW FAST THE CAR IS GOING AT THE TIME). I NOTICED THIS SHORTLY AFTER PURCHASING AND RECEIVING THE CAR ON 24 OCT. 2009. MENTIONED TO TOYOTA SERVICE STAFF AT A NEW CAR ORIENTATION PROGRAM, BUT WAS TOLD THAT THEY HAD NOT HEARD OF THIS ISSUE... AND PERHAPS THE BUMPS IN THE ROAD WERE CAUSING ME TO NOT APPLY EVEN PRESSURE ON THE BRAKE. I HAVE ADJUSTED MY DRIVING ROUTE AS TO NOT TO GO OVER THE POTHOLE WHICH CAUSES THE MOST PROBLEMS (OR TRY TO BE VIGILANT ABOUT SITUATIONS WHICH MAY CAUSE LURCHING) BUT WAS CONCERNED WHEN I SAW AN ARTICLE REPORTING THAT OTHER PEOPLE ARE EXPERIENCING SIMILAR ISSUES (HTTP://WWW.FREEP.COM/ARTICLE/20100203/BUSINESS01/100203028/1318/2010-PRIUS-OWNERS-COMPLAIN-OF-FAULTY-BRAKES-LURCHING-OVER-BUMPS). *TR

THE REGENERATIVE BRAKING ON THE 2010 PRIUS LOSE GRIPPING WHEN GOING OVER BUMPS ON THE ROAD. WHAT HAPPENS IS WHEN THE CAR GOES OVER BUMPY GROUND AND I AM USING THE BRAKES, THE BRAKES SEEM TO LOSE GRIP AND THE DECELERATION IS REDUCED. I HAVE NOTICED THIS HAPPENING ABOUT 10 TIMES IN THE 6 MONTHS THAT I'VE OWNED THE VEHICLE. *TR

I HAVE EXPERIENCED PROBLEMS WHILE BRAKING IN MY 2010 TOYOTA PRIUS. THE PROBLEM OCCURS WHEN I AM BRAKING AND THE CAR HITS A BUMP/POT HOLE. WHEN I HIT A BUMP THE BRAKES SEEM TO STOP WORKING FOR A SECOND OR TWO AND THE CAR LURCHES FORWARD. FOR A MOMENT OR TWO YOU FEEL LIKE YOU ARE LOSING CONTROL OF THE CAR. LUCKILY THIS HAS NOT RESULTED IN AN ACCIDENT YET. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHEN DEPRESSING THE BRAKES TO STOP THE VEHICLE IT IS GRABBING AND JERKING. WHILE USING THE VEHICLE'S SPEED CONTROL UPON SETTING IT THE VEHICLE WOULD ACCELERATE, BUT WHEN THE BRAKES ARE APPLIED THE VEHCILE WOULD OPERATE NORMALLY. THE CONTACT STATED THAT HE MONITORS THE FAILURES. THE VEHICLE HAS NOT YET BEEN DIAGNOSED BY THE DEALER.THE FAILURE MILEAGE 6,200.

I HAVE A 2010 PRIUS. I HAVE HAD 2 OCCASIONS WHERE I HAVE HIT BUMPS IN THE ROAD AND MY CAR ACCELERATES WITHOUT ME TOUCHING THE GAS PEDAL. *TR

WHEN DRIVING AT MODERATE SPEEDS ON CITY/SURFACE STREETS IN MY 2010 PRIUS, A BRAKING PROBLEM OCCURS. IF I HIT A BUMP IN THE ROAD WHILE BRAKING, THE VEHICLE LURCHES FORWARD AS IF THE BRAKES HAVE DISENGAGED, EVEN THOUGH I AM STILL PRESSING THE BRAKE. I PUSH THE BRAKES DOWN HARDER AND NOTHING HAPPENS. A FEW SECONDS LATER, THE BRAKES COME BACK INTO PLAY AND THE CAR SLOWS DOWN AGAIN. THIS HAS HAPPENED SEVERAL TIMES, AND I HAVE NARROWLY AVOIDED ACCIDENTS CAUSED BY THIS SEVERAL TIMES. *TR

CARE SPEEDS UP WITH BREAKS APPLIED WHEN THE CAR HITS A BUMP. THE BRAKES ALSO GRAB WHEN BACKING UP. FREQUENCY: NOT OFTEN BUT IT NEED TO BE CORRECTED BEFORE SOMEONE GETS HURT. REPORTED TO TOYOTA. THEY HAVE CHECKED AND FOUND NOTHING WRONG. THERE IS NOT ONE DATE AS IT HAS HAPPEN SEVERAL TIMES OVER THE LAST 7 MONTHS. *TR

I OWN A 2010 TOYOTA PRIUS AND HAVE NOTICED THAT IF YOU ARE APPLYING THE BRAKES AND ONE OF THE WHEELS OF THE CAR HAPPEN TO HIT A POTHOLE OR BUMP THE BRAKES SEEM TO MOMENTARILY RELEASE AND THEN GRAB AGAIN. MY FOOT IS NOT COMING OFF THE BRAKE PEDAL. IT'S AS IF THE CAR LUNGES AHEAD FOR A SPLIT SECOND. THIS HAS HAPPENED MORE THAN ONCE. *TR

2010 PRIUS, WITH NO MODIFICATION MADE SINCE PURCHASE. WHEN DRIVING AND COMING TO A STOP, THE BRAKE PEDAL WAS APPLIED TO STOP THE CAR. THE CAR HIT A POTHOLE/SHARP BUMP 5 FEET BEFORE THE STOP SIGN AND THE CAR JERKED FORWARD FRIGHTENINGLY WHILE THE BRAKE WAS DEPRESSED. THE BRAKE PEDAL LOST ITS BREAKING ABILITY FOR 1 OR 2 SECONDS, BUT BECAME OPERATIONAL AGAIN AFTER THAT. DURING THE 1 OR 2 SECONDS, I FELT I LOST CONTROL OF THE CAR. THIS DEFECT IS REPRODUCIBLE AND HAS OCCURRED 5 TIMES SINCE I BOUGHT THE CAR 6 MONTHS AGO. THIS IS VERY SCARY AND I THINK WILL CAUSE AN ACCIDENT IF NOT FIXED. *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

EXPERIENCE SUDDEN LOSS BRAKING POWER WHEN MY PRIUS HIT A POTHOLE WHILE APPLYING THE BRAKE PEDAL. THE CAR REGAIN BRAKING POWER AFTER SHORT PERIOD OF TIME. THIS ISSUE HAPPENED MULTIPLE TIMES. I'M CONCERN MY CAR MAY HIT OTHER VEHICLE OR PEDESTRIAN IN THE FUTURE IF I WOULD NOT STOP THE CAR PROPERLY. *TR

WE PURCHASED OUR 2010 PRIUS IN AUGUST 2009. SINCE THEN, MY WIFE HAS COMPLAINED SEVERAL TIMES ABOUT HOW THE BRAKES SEEM TO STOP WORKING WHENEVER SHE IS BRAKING AND ENCOUNTERS A BUMP (LIKE A POTHOLE OR SPEED BUMP). I'VE NOTICED IT A COUPLE OF TIMES MYSELF .. IT FEELS LIKE THE BRAKES ARE NO LONGER FUNCTIONING AND YOU HAVE TO RELEASE THE PEDAL AND PUSH IT DOWN AGAIN TO RE-ENGAGE THE BRAKES. FORTUNATELY, WE HAVEN'T HIT ANYTHING, YET -- BUT IT IS A RECURRING ISSUE. *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

I BOUGHT A 2010 TOYOTA PRIUS IN JUNE OF 2009. ON SEVERAL OCCASIONS, I HAVE NOTICED THE BRAKES NOT WORKING PROPERLY WHEN I HAVE TRIED BRAKING WHILE GOING OVER A SPEED BUMP. INSTEAD OF SLOWING OR STOPPING, THE CAR FEELS LIKE IT ACTUALLY IS LURCHING FORWARD. IT CORRECTS ITSELF ALMOST IMMEDIATELY, BUT THERE IS THAT SECOND WHEN IT FEELS LIKE IT ISN'T GOING TO STOP. IN READING SEVERAL STORIES ABOUT REPORTED BRAKE ISSUES WITH THE PRIUS, I REALIZED THAT OTHER PEOPLE ARE HAVING THE SAME ISSUE. I HAVE PUT IN BELOW THE APPROXIMATE DATE THAT WAS THE LAST TIME THIS HAPPENED. *TR

I'M THE OWNER OF A 2010 PRIUS AND TWICE NOW WHEN APPLYING THE BRAKES FIRMLY DURING A RAIN SOAKED DAY WHILE GOING OVER THE TEMPORARY STEEL PLATES USED DURING ROAD REPAIRS AS SOON AS THE BACK WHEELS HIT THE SURFACE THE CAR SHOOTS A HEAD AS IF THE BRAKES ARE TEMPORARILY NOT APPLYING PRESSURE AT ALL. NO ONE WAS HURT IT IS JUST VERY UNSETTLING . *TR

2010 PRIUS WE HAVE HAD A PROBLEM WITH THE BRAKES RELEASING WHEN WE DRIVE OVER POT HOLES OR A SLICK SURFACE. THIS HAS BEEN A REOCCURING THING. IT PREVENTS US FROM STOPPING QUICKLY OR REACTING TO A SITUATION. IT HAS NOT RESULTED IN AN ACCIDENT, BUT IT SEEMS LIKE IT HAS A STRONG POSSIBILITY TO IN THE NEAR FUTURE. *TR

2010 TOYOTA PRIUS. I PURCHASED A 2010 TOYOTA PRIUS SERIES V IN JULY 2010 ... I HAVE NOTICE THAT WHEN GOING OVER A "POTHOLE" OR VERY ROUGH PAVEMENT THAT THE VEHICLE DOES SOMEWHAT SPEED UP AND HAVE A MOMENTARY LOSS OF BRAKING CAPABILITY. STEPPING ON THE BRAKE SEEMS TO ALLEVIATE THE SITUATION. SEEMS TO INTERMITTENT AND DID NOT HAPPEN ON ANY SPECIFIC DATE OR CAUSE AN ACCIDENT . *TR

MY VEHICLE HAS GONE INTO A SLIDE WHEN BRAKING...FEELS LIKE THE BRAKES ARE LOCKED ALTHOUGH I HAVE ANTILOCK BRAKES. I HAVE SLID INTO AN INTERSECTION TWICE AND I WOULD SAY THERE WAS SAND LEFT OVER FROM SNOW MELT. THIS IS A BRAND NEW CAR AND I DEFINITELY CAN FEEL A DIFFERENCE THAT HAS CAUSED ALARM POSSIBLY 4 OR 5 TIMES IN 4 MONTHS. *TR

TOYOTA-PRIUS HYBRID-2010 BRAKING PROBLEM. I HAVE EXPERIENCE A BRAKING PROBLEM THAT HAS NOT RESULTED IN AN ACCIDENT. THE BRAKING PROBLEM RESULTS ONLY WHEN IN A PANIC STOP (WHEN ABS IS ACTIVE). I THINK WHAT IS HAPPENING IS THAT THE BRAKE IS RELEASING FOR A SECOND WHILE THE ABS COMPUTER IS TAKING OVER CONTROL OF THE BRAKING. THIS CAUSE WHAT SEEMS TO THE DRIVE AS A SLIP. WHERE THE DRIVE FEELS THE BRAKE RELEASE AND A SECOND LATER THE ABS KICKS IN AND STOPS THE CAR. I HAVE FELT THIS BRAKE RELEASE THREE TIMES IN THE FEW MONTHS I HAVE OWNED THE CAR AND MOST TIMES WHEN TURNING RIGHT INTO A DRIVEWAY. *TR

WHILE DRIVING MY 2010 PRIUS, I HAVE EXPERIENCED UNINTENDED BRAKE RELEASE ON 6 OCCASIONS SINCE TAKING DELIVERY OF THE CAR IN JUNE 2009. DURING THE SUMMER, ON DRY PAVEMENT, THE 1ST INCIDENT OCCURRED WHILE APPROACHING AN INTERSECTION AND GOING INTO A RIGHT TURN, THE LEFT FRONT WHEEL ROLLS OVER A (FLUSH TO THE PAVEMENT) MANHOLE COVER. THE CAR LOST BRAKING AND JUMPED/SLIPPED FORWARD. FORTUNATELY, THERE WAS NO CAR CLOSE IN FRONT OF ME. THIS OCCURRED 2X AS THIS IS ONE OF MY NORMAL ROUTES TO WORK. ON 2 OTHER OCCASIONS, NEAR MY HOME APPROACHING AN INTERSECTION IN WHICH I NEEDED TO SLOW DOWN, THE CAR JUMPED WHEN APPLYING THE BRAKES. THE PAVEMENT WAS IN 2 SECTIONS (SPLIT HORIZONTALLY), ONE PART CONCRETE AND THE ADJOINING SECTION ASPHALT. THE CAR SLIPPED/JUMPED FORWARD WHILE BRAKING. THE 5TH OCCASION OCCURRED APPROACHING AN INTERSECTION AND THE CAR LURCHED FORWARD AS I TRIED TO STOP ALMOST HITTING THE CAR IN FRONT OF ME. THIS WAS ON DRY PAVEMENT, DON'T KNOW THE REASON. GOING OVER POTHOLES ON AT LEAST 1 OCCASION,THE SAME REACTION. HAD MENTIONED TO THE DEALERSHIP SEVERAL TIMES, THE FIRST TIME BEING AT A NEW OWNER ORIENTATION MEETING. THEY WERE NOT FAMILIAR WITH THIS ISSUE. WAS ADVISED IF IT KEEPS OCCURRING, TO BRING THE CAR IN FOR AN INSPECTION. I NOW HAVE AN INSPECTION SCHEDULED FOR FRIDAY FEB 5TH AT THE DEALERSHIP. *TR
