2010 TOYOTA PRIUS BRAKING PROBLEM. I BOUGHT A 2010 TOYOTA PRIUS APPROX 4 MONTHS AGO. DURING THE APPROX 10000 MILES I HAVE PUT ON THE CAR, I HAVE EXPERIENCED A BRAKING ISSUE APPROX 5 TO 6 TIMES. MOST TIMES I WAS BRAKING FOR A STOP SIGN IN A 30 MPH ZONE. ONCE I WAS BRAKING FOR A RED LIGHT IN A 45 MPH ZONE. EACH TIME, THERE WAS BUMPY ROAD DURING THE BRAKING, AND THE BRAKES RELEASED. I CAN'T SAY IF THE CAR ACCELERATED, OR IT JUST SEEMED THAT WAY BECAUSE OF THE BRAKE RELEASE. IT DID NOT CAUSE ANY ACCIDENTS, BUT ONCE IT WAS ON A SNOW COVERED HILL AND I SLID OUT INTO A 2 LANE 50 MPH HIGHWAY. THERE WAS NO TRAFFIC, AND THEREFORE NO ACCIDENT. ANOTHER TIME, I WAS STOPPING FROM 45 MPH AT A RED LIGHT, AND UNDER BRAKING, AGAIN ON BUMPY ROADS, THE BRAKES RELEASED AND I NEARLY HIT THE CAR IN FRONT OF ME. THE BRAKES RELEASED ENOUGH ALLOW ME TO PANIC AND JAM THE BRAKE PEDAL TO THE FLOOR. THE CAR STOPPED QUICKLY. *JB

WHEN APPLYING THE BRAKES TO COME TO A STOP AT A RED LIGHT, MY 2010 TOYOTA PRIUS IV HIT SOME ROUGH ROAD AND BEGAN TO SURGE/ACCELERATE EVEN WITH MY FOOT ON THE BRAKE. I PRESSED HARDER UNTIL THE BRAKES WERE RE-ENGAGED. THIS HAS HAPPENED UNDER SIMILAR CIRCUMSTANCES (ROUGH ROAD) THREE TIMES SINCE TAKING OWNERSHIP OF THE CAR SEPT 15, 2009. *JB

MY 2010 TOYATA PRIUS (PURCHASED IN SEPT. 2009) HAS HAD REPEATED PROBLEMS WHILE BRAKING OVER A PATCH OF ROAD WITH SMALL POTHOLES. IF THE BRAKES ARE ENGAGED WHILE OVER THE PATCH OF UNEVEN ROAD, THE CAR LURCHES OR "JUMPS" OVER THE SPOT ON THE ROAD AND THE BRAKES DON'T BEGIN TO CATCH UNTIL THE CAR GETS OVER THE PATCH. THIS HAS HAPPENED 5-10 TIME OVER THE LAST FOUR MONTHS AT A STOP LIGHT. *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

APPLIED BRAKES AT A STOP LIGHT. THE PRIUS (PURCHASED IN JULY OF 2009) RAN OVER A BUMP, AND IT SEEMED LIKE THE BRAKE DISENGAGED. I REMOVED MY FOOT FROM THE BRAKE PEDAL AND REAPPLIED THE BRAKES. THE BRAKES SEEMED TO ENGAGE AND CAME TO A STOP. *JB

1. I WAS DRIVING ON A LOCAL ROAD AND WAS SWITCHING LANES. I PRESSED MY BRAKE PEDAL VERY SLIGHTLY AS I WAS CROSSING THE LANE DIVIDER AND AS I HIT ONE OF THE PLASTIC BUMPS, MY CAR ACCELERATED FORWARD. 2. THIS HAS RECURRED MANY TIMES AND THERE WERE NO VEHICLES IN FRONT OF ME EVERYTIME IT HAPPENED SO I WAS ABLE TO COME TO A STOP. SEVERAL TIMES I WOULD EITHER CROSS THE PEDESTRIAN WALKWAY AT THE INTERSECTION WHEN THIS ACCELERATION OCCURS. 3. I TOOK MY CAR TO THE DEALER SEVERAL TIMES AND EVERYTIME THEY TOLD ME IT WAS NORMAL AND THERE WAS NO PROBLEM. THEY WERE LYING AND COMPLETELY CLUELESS!!!*JB

THE BRAKES ON MY 2010 TOYOTA PRIUS FAILED TO ENGAGE WHILE DRIVING OVER A POTHOLE. THE CAR SEEMED TO ACCELERATE BRIEFLY BUT THEN THE BRAKES KICKED IN ONCE I HIT THE BRAKE PEDAL AGAIN HARDER. THIS IS THE THIRD INCIDENT OF SIMILAR PROBLEMS SINCE I PURCHASED THE VEHICLE IN JULY 2009. *JB

I DRIVE A 2010 TOYOTA PRIUS. ON MULTIPLE OCCASIONS WHILE ATTEMPTING TO SLOW DOWN ON ROUGH SURFACES, THE BRAKES TEMPORARILY STOPPED WORKING FOR 1-2 SECONDS EVEN THOUGH THE BRAKE PEDAL WAS DEPRESSED. THE MOST RECENT INCIDENT OCCURRED WHILE EXITING THE HIGHWAY AND ATTEMPTING TO SLOW DOWN QUICKLY ON ROUGH PAVEMENT. LUCKILY, THERE WERE NO OTHER CARS IN FRONT OF ME OR THERE WOULD HAVE BEEN A COLLISION. IF A CAR HAD BEEN IN FRONT OF ME ON ANY OF THE OCCASIONS THEN THERE WOULD HAVE LIKELY BEEN A COLLISION. *JB

WE DRIVE A 2010 PRIUS, PURCHASED THIS FALL. ON THREE SEPARATE OCCASIONS, WHEN I TRIED TO BRAKE IN AN AREA WITH SOME ICE, THE CAR ACCELERATED RATHER THAN STOPPED. ON TWO OF THE OCCASIONS, I FAILED TO STOP AT AN INTERSECTION (NO ONE COMING IN THE OPPOSITE DIRECTION) AND ON THE THIRD, THE ICE PATCH WAS ABOUT 3 FT IN DIAMETER ON ONE SIDE OF THE CAR ONLY. I WAS GOING RATHER SLOWLY, FOLLOWING A CAR THAT SLOWED FOR A SPEED BUMP. LUCKILY THE OTHER CAR ACCELERATED AND I DID NOT HIT IT. THE SPEED BUMP SLOWED ME DOWN AND THEN THE BRAKES STARTED WORKING. *JB

ON OCCASION THE BRAKING ON OUR 2010 PRIUS HAS NOT FELT RIGHT. SOMETIMES WHEN BRAKING AND HITTING A BUMP OR POTHOLE, THERE SEEMS TO BE A BRIEF PERIOD WHERE THE CAR FEELS LIKE ITS ACCELERATING OR THE BRAKES ARE NOT SLOWING IT DOWN PROPERLY. KEEPING PRESSURE ON THE BRAKES GETS BY THE PROBLEM BUT IT IS VERY UNSETTLING AND I HAVE NEVER HAD THIS PROBLEM WITH BRAKES IN ANY CAR BEFORE. IT HAS HAPPENED A FEW TIMES SINCE WE BOUGHT THE CAR IN JULY 2009 BUT VERY INTERMITTENTLY. THE DATE I AM PICKING IS JUST AN APPROXIMATE DATE FOR ONE OF THE INCIDENTS. I AM REPORTING THIS NOW IN LIGHT OF THE RECENT PUBLICITY ABOUT SIMILAR EVENTS REPORTED BY OTHER OWNERS, WHICH MADE ME REALIZE WHAT I HAD BEEN NOTICING WAS A REAL ISSUE. *JB

I OWN A 2010 TOYOTA PRIUS WHICH WAS PURCHASED IN SEPTEMBER 2009. MY BRAKES FAIL TO IMMEDIATELY STOP MY CAR WHEN APPLIED GOING OVER BUMPY SECTIONS IN THE ROAD, HITTING A POTHOLE, OR WHEN ON SLIPPERY SECTIONS OF THE ROAD. WHEN HITTING A BUMP IT ACTUALLY FEELS LIKE THE CAR LURCHES FORWARD. THE CAR WILL EVENTUALLY STOP AFTER PUSHING THE BRAKE TO THE FLOOR WITH FORCE. IT IS VERY DISCONCERTING AND THE POTENTIAL FOR HITTING THE CAR IN FRONT OF YOU OR A PERSON IS VERY HIGH. *JB

SERVICE BRAKES, HYDRAULIC
THE BRAKES ON MY PRIUS HAVE FAILED THREE TIMES IN THREE WEEKS IN BOTH CITY AND RURAL DRIVING CONDITIONS--TWO TIMES I WAS BRAKING WHILE DRIVING DOWN A HILL (BOTH UNDER 30 MPH) AND ONCE WHILE DRIVING ON A SECONDARY BLACKTOP ROAD (35 MPH). *TR WHEN BRAKE FAILURE OCCURS, THE PRIUS BRAKES NOT ONLY DISENGAGE (FAIL) BUT THE CAR SEEMS TO LUNGE FORWARD. IT'S AS IF I AM BRAKING WITH MY FOOT ON THE GAS PEDAL AND THEN LET UP ON THE BRAKE WHILE THE GAS PEDAL IS STILL DEPRESSED. IT'S A NAUSEATING FEELING WHEN THIS HAPPENS. I WAS PLANNING ON TAKING THE PRIUS ON A CROSS-COUNTRY TRIP IN THE SPRING BUT WILL NOT NOW BECAUSE OF THIS BRAKING ISSUE. IT IS NOT A SAFE VEHICLE. I HAVE GREAT CONCERN FOR MY SAFETY AND THE SAFETY OF OTHERS, PARTICULARLY PEDESTRIAN SAFETY AT INTERSECTIONS. I AM ALSO GOING TO POST MY COMPLAINT ON PRIUSCHAT.COM (ONLINE PRIUSPHILE COMMUNITY OF WHICH I AM A MEMBER) IN HOPES THAT OTHERS WILL COME FORWARD WITH THEIR BRAKING PROBLEMS TO NHTSA, FORCING TOYOTA TO FIX THIS PROBLEM. I COMPLETED A COMPLAINT FORM FOR LAST WEEK ON YOUR SITE (DIDN'T REQUIRE VIN NUMBER) BUT SINCE BRAKE FAILURE OCCURRED AGAIN TODAY, I REALIZE THAT THIS IS NOT AN ISOLATED INCIDENT. THEREFORE, I AM FILING THIS FORMAL NHTSA COMPLAINT. *TR

I WOULD LIKE TO ADD MY REPORT TO YOUR OTHER COMPLAINTS ABOUT 2010 TOYOTA PRIUS BRAKES. I PURCHASED MINE IN JULY AND SINCE THEN HAVE EXPERIENCED 4 (FOUR) INSTANCES OF THIS PROBLEM. IN EACH CASE, I WAS DECELERATING WITH THE BRAKES STEADILY APPLIED, AND ROLLED OVER A BUMP OR POTHOLE IN THE ROAD. AT THAT MOMENT, THE BRAKES STOPPED WORKING, OR THE BRAKING POWER WAS SEVERELY REDUCED, AND THE CAR FELT AS IF IT LURCHED FORWARD. APPLYING MORE PRESSURE ON THE BRAKES WHEN THIS OCCURS DOES CAUSE THE BRAKING TO RESUME, BUT THERE IS A DELAY OF PERHAPS 1/2 SECOND. I HAVE NOT HAD AN ACCIDENT SO FAR, BUT IF I WERE BEHIND ANOTHER CAR WHICH WAS ALSO BRAKING WHEN THIS HAPPENED, THERE IS A HIGH LIKELIHOOD THAT MY CAR WOULD SMASH INTO THE OTHER CAR'S REAR. *TR

UNKNOWN OR OTHER
SINCE I BOUGHT MY 2010 PRIUS I'VE EXPERIENCED PROBLEMS WITH THE BRAKES. THE CAR EXPERIENCES A SUDDEN SURGE OF POWER WHEN GOING OVER BUMPS OR HITTING POTHOLES IF THE BRAKES ARE BEING APPLIED AT THE TIME. THIS HAPPENS AT ANY SPEED AT ANY TIME OF DAY, ONLY WHEN THE BRAKES ARE BEING APPLIED LIGHTLY. THIS PROBLEM OCCURS SEVERAL TIMES A WEEK, ALWAYS WHEN HITTING BUMPS, POTHOLES OR UNEVEN PAVEMENT. IT ALWAYS IS A SUDDEN, VERY BRIEF SURGE OF POWER, SOMETIMES ENOUGH TO PUSH ME BACK INTO THE SEAT. SO FAR THERE HAVE BEEN NO CONSEQUENCES OTHER THAN VERY FRAYED NERVES. I'VE REPORTED THIS TO MY DEALER WHO RESPONDED THAT THE CAR WAS A NEW TECHNOLOGY AND I SIMPLY DIDN'T KNOW HOW TO DRIVE IT PROPERLY. I LEARNED IN SUBSEQUENT CONVERSATIONS DIRECTLY WITH THE MECHANIC THAT OTHERS HAD COMPLAINED ABOUT THIS PROBLEM BUT THEY HAD NO IDEA WHAT WAS CAUSING IT. TO DATE, THE DEALER HAS DONE NOTHING ABOUT IT. THE ONLY THING THAT FIXES THE PROBLEM IS TO BRAKE FURTHER FROM A STOP OR TO ROLL OVER BUMPS BEFORE BRAKING. I'M VERY CONCERNED ABOUT A SITUATION WHERE I NEED TO BRAKE SUDDENLY BUT THE CAR SURGES, POSSIBLY CAUSING A CRASH. *TR

I HAVE A 2010 TOYOTA PRIUS, AND I AM SHOCKED THAT THIS CAR WAS NOT INCLUDED IN THE GIGANTIC TOYOTA RECALL. WHY? BECAUSE THE 2010 TOYOTA PRIUS EXHIBITS BRAKE FAILURE AND SUDDEN ACCELERATION WHILE SLOWING DOWN ON BUMPY ROADS. FOR EXAMPLE, IF YOU'RE SLOWING DOWN TOWARDS A RED LIGHT, AND THEN ALL OF A SUDDEN YOU HIT A POTHOLE, THE CAR WILL SUDDENLY ACCELERATE AND MAY CAUSE A CRASH WITH THE PERSON AHEAD OF YOU! THIS HAPPENS ALL THE TIME AND IS EXTREMELY DANGEROUS. THOUSANDS OF 2010 PRIUS DRIVERS WORLDWIDE ARE ALSO HAVING THIS BRAKE FAILURE/SUDDEN ACCELERATION ISSUE WITH THEIR 2010 PRIUS AS WELL! TAKE A LOOK AT JUST A FEW OF THESE DISCUSSIONS WHICH ARE TAKING PLACE, WHERE PEOPLE ARE HAVING UNCONTROLLABLE SUDDEN ACCELERATION WITH THEIR 2010 PRIUS: HTTP://TINYURL.COM/YJ359RH WILL NHTSA PLEASE DO SOMETHING ABOUT THIS? *TR

SERVICE BRAKES, HYDRAULIC, VEHICLE SPEED CONTROL
I OWN A 2010 PRIUS AND TOOK THE CAR INTO THE LOCAL TOYOTA DEALER 2 DAYS AGO FOR THE INITIAL 5,000 MILE CHECK UP TO DISCUSS A COUPLE ISSUES I HAVE FOUND WITH THE CAR. I HAVE EXPERIENCED ON 3 OCCASIONS A FEELING OF BRAKE FAILURE. THIS HAS OCCURRED WHEN I AM DRIVING OVER ROUGH ROAD. WHILE THE BRAKE IS BEING APPLIED IF I HIT BUMPS, THE BRAKE PEDAL DROPS AND I LOSE THE BRAKES. I HAVE IMMEDIATELY LET UP ON THE BRAKE AND THEN REAPPLIED PRESSURE TO THE BRAKE PEDAL TO GET BRAKING BACK. THE DEALER TRIED TO ACHIEVE THE SAME PROBLEM BUT WAS UNABLE TO REPLICATE IT. HE SAID IT WAS JUST THE WAY THE PEDAL MUST FEEL TO ME. OUR DAUGHTERS BOTH HAVE 2006 PRIUS' WHICH I HAVE DRIVEN AND NEVER EXPERIENCED THIS PROBLEM WITH THEIR CAR BRAKES. THE SECOND PROBLEM IS WITH CRUISE CONTROL. AGAIN, I HAVE DRIVEN A 2006 PRIUS AND USED CRUISE CONTROL AND NOT EXPERIENCED THE FOLLOWING IN THE 06 MODEL THAT OCCURS IN OUR 2010 MODEL. THE CAR STARTED TO ACCELERATE IN CRUISE MODE. WE HAVE ALSO FOUND IT TAKES A LOT OF PRESSURE ON THE BRAKE PEDAL TO TAKE IT OUT OF CRUISE CONTROL. THE CAR JERKS WHEN TAPPING THE BRAKE PEDAL LIGHTLY TO TAKE OFF CRUISE CONTROL. THE DEALER AGAIN TOOK IT OUT FOR A TEST DRIVE AND SAID THIS IS THE WAY THE PRIUS FEELS. I KNOW DRIVING THE 2006 MODEL IT WAS NOT THE WAY THE PRIUS FEELS WHEN YOU TAKE IT OUT OF CRUISE CONTROL. *TR
