2010 Toyota Prius complaints

2010 TOYOTA PRIUS. ACCELERATION WHEN APPLYING BRAKE IN BUMPY ROAD. IT HAPPENED WHEN THE SPEED IS SLOW AND THERE IS UNEVEN OR DRIVES OVER POT HOLE. *TR

SUDDEN SURGE WHEN HITTING A BUMP AT MEDIUM SPEEDS. MY PRIUS IS NOW SIX MONTHS OLD WITH ABOUT 6,000 MILES ON IT AND I EXPERIENCE A SURGE IN ACCELERATION WHEN I HIT A BUMP AT ABOUT 20 MPH. I USED TO BE AN AUTO MECHANIC (20 YEARS AGO), SO I MAY BE A LITTLE MORE ATTUNED TO NARROWING THE PROBLEM THAN MOST PEOPLE. I HAVE NOTICED THAT WHEN THIS SURGE HAPPENS I AM LIGHTLY ON THE BRAKES (TOTALLY OFF THE ACCELERATOR). THIS SEEMS TO PARTICULARLY HAPPEN WHEN THE BUMP (LIKE A POTHOLE IN THE ROAD) IS UNDER THE RIGHT FRONT WHEEL. EVEN MORE FRUSTRATING IS THAT THIS DOES NOT HAPPEN EVERY TIME NOR ON EVERY BUMP. I CAN TELL YOU THE FLOOR MAT HAS NOTHING TO DO WITH IT AND I DO NOT THINK THE OUTSIDE TEMPERATURE HAS ANYTHING TO DO WITH IT EITHER. MY SHADETREEMECHANIC'S DIAGNOSIS IS THAT THIS IS A SOFTWARE GLITCH THAT GETS ACTIVATED WHEN THE BRAKING SOLENOID IS BUMPED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT WAS DRIVING 30MPH TRAVELING OVER A ROUGH TERRAIN HE ATTEMPTED TO BRAKE AND NOTICED THAT THE VEHICLE SUDDENLY SURGED FORWARD BEFORE THE BRAKES WOULD ACTIVATE. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALERSHIP AND THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 1500.

OCCASIONALLY WHEN BRAKING AT A RELATIVELY SLOW SPEED ON A BUMPY OR SLIPPERY SURFACE THE BRAKES FEEL LIKE THEY STOP WORKING. MY IMMEDIATE RESPONSE IS TO PRESS THE BRAKES HARDER AND THAT SEEMS TO RESOLVE THE ISSUE. I DON'T REMEMBER ANY SENSE THAT THE ABS SYSTEM KICKED IN DURING THESE SITUATIONS. I HAVE NEVER NOT PRESSED HARDER ON THE BRAKE PEDAL SO DON'T KNOW WHETHER THE LOSS OF BRAKING SENSATION WOULD CONTINUE IF NO MORE PRESSURE WAS APPLIED TO THE BRAKES. I HAVE ALSO FELT THIS SENSATION WHEN BRAKING WHILE CORNERING AT SLOWER SPEEDS. I DON'T KNOW IF A SLIPPERY OR BUMPY SURFACE IS ALWAYS INVOLVED WHEN I EXPERIENCE THE LOSS OF BRAKING WHILE TURNING, BUT AT LEAST ON ONE OCCASION DURING CORNERING THERE HAS BEEN A BUMP GOING FROM A SLIGHTLY RAISED ASPHALT SURFACE TO LOWER CONCRETE SURFACE ATTACHED TO THE CURB FOR THE PASSENGER SIDE WHEEL ONLY. *TR

WHILE DRIVING MY 2010 TOYOTA PRIUS ON ROADS WITH LOTS OF BUMPS, POTHOLES, SEWER COVERS, ETC, I HAVE BRAKING PROBLEMS. WHEN DRIVING OVER ONE OF THESE "OBSTACLES" AND I TOUCH THE BRAKES, THE CAR LURCHES FORWARD AS IF ACCELERATING OR SLIPPING. I CAN THEN RELEASE THE BRAKE AND STEP ON IT AGAIN TO SLOW/STOP THE CAR, BUT IF THERE WAS A CAR CLOSE IN FRONT, I WOULD HAVE CERTAINLY HIT IT. I PURCHASED THE CAR IN AUGUST 2009 AND HAVE HAD THIS SAME PROBLEM HAPPEN AT LEAST 6-10 TIMES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED AS SHE WAS DRIVING 5 MPH SHE SLOWED DOWN AND APPLIED THE BRAKE TO STOP THE VEHICLE AND IT LUNGED FORWARD. THIS HAPPEN TWICE. THE VEHICLE HAD NOT BEEN TAKEN TO THE DEALER . THE FAILURE MILEAGE WAS 1,000.

DRIVING 35MPH ON STRAIGHT ROAD AND RAN OVER SOME UNSEEN POTHOLES. APPLIED BRAKES AND THEY DID NOT FUNCTION AS EXPECTED. MUCH LESS BRAKING POWER THAN NORMAL. *TR

I HAVE HAD THE FOLLOWING OCCUR SEVERAL TIMES SINCE I PURCHASED THE VEHICLE IN JULY 2009: WHEN BRAKING ON SNOW OR ICE OR BRAKING WHEN PASSING OVER A BUMP OR POTHOLE THE BRAKES WILL FEEL AS IF THEY ARE SLIPPING AND THE CAR WILL ACCELERATE FOR A FRACTION OF A SECOND. IT'S AS IF THE ABS IS RELEASING THE BRAKES TOO LONG BEFORE REENGAGING THEM, RESULTING IN THE CAR TO STOP DECELERATING MOMENTARILY. *TR

DEAR, NHTSA I WAS DRIVING MY PRIUS IN NOVEMBER OF 2010 AND NOTICED THAT THE BRAKING SYSTEM WAS NOT BRAKING WELL. I RECENTLY WAS INVOLVED ON JAN 29, 2010 IN AN INCIDENT DRIVING OUT OF THE PARKING LOT FROM WORK WERE THE BRAKES FAILED ON THE VEHICLE WHEN I WENT TO STOP THE VEHICLE AND THE CAR SKIDDED AND STRUCK SOME ICE/SNOW (ONE THE EDGE OF THE PARKING LOT) CAUSING DAMAGE TO MY FRONT PASSENGER SIDE BUMPER. I AM NOT AS CONCERNED ABOUT THE DAMAGE AS I AM ABOUT MY OVERALL SAFETY IN THE VEHICLE. I HAVE REPORTED THE PROBLEM TO TOYOTA AND THEY HAVE RESPONDED AND I HAVE TOLD THEM THAT THERE IS AN ISSUE WITH THE BRAKING. I WANT TO TAKE THIS TIME TO FORMALIZE MY COMPLAINT. I AM NOT CHECKING CRASH AND PROPERTY DAMAGE DUE TO THE FACT THAT IT IS NOT WELL DEFINED ON THIS PAGE ALTHOUGH I HAD PROPERTY DAMAGE TO THE CAR ITSELF AND I CRASHED INTO SNOW/ICE ON THE SIDE OF THE ROAD. *TR

MY 2010 PRIUS HAS BEEN EXHIBITING MOMENTARY LOSS OF BRAKING WHEN PASSING OVER A ROUGH SURFACE. MY NEIGHBORHOOD HAS SEVERAL ROADS WITH STEEP SLOPES AND ALTHOUGH MY SPEED ON THESE ROUTES IS ALMOST ALWAYS UNDER 20 MPH, ON SEVERAL OCCASIONS I HAVE NOTICED AN UNEASY FEELING OF LOSS OF CONTROL ON PASSING OVER POTHOLES OR SEAMS IN THE PAVEMENT WHEN GOING DOWNHILL. I HAD WRITTEN THIS OFF TO UNFAMILIARITY WITH A NEW VEHICLE, SINCE I ONLY PURCHASED THE CAR ON 12/31/09 BUT WHEN I READ TODAY'S NY TIMES ARTICLE, THE SYMPTOMS IT DESCRIBED WERE EXACTLY WHAT I HAD BEEN EXPERIENCING. I HAVE NOT YET CONTACTED THE DEALERSHIP BUT PLAN TO DO SO RIGHT AWAY. *TR

WHEN BRAKING AND GOING OVER ROUGH ROAD OR POTHOLES, THE CAR FEELS LIKE IT IS ACCELERATING. IT IS NECESSARY TO EXERT ADDITIONAL PRESSURE ON THE BRAKE PEDAL, BUT SOMETIMES DOES NOT FEEL LIKE THIS IS HELPING. *TR

2010 PRIUS ACCELERATES WHEN DRIVING OVER SPEED BUMP, POT HOLE OR OTHER UNEVEN SURFACES. *TR

DRIVING OVER A BUMP OR POTHOLE AND MY BRAKES TEMPORARILY QUIT WORKING. 2010 PRIUS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONSUMER STATED THE PROBLEM HAS OCCURRED A TOTAL OF 4 TO 5 TIMES. THE DEALER WAS CONTACTED AND THEY STATED THAT THEY NEVER HEARD OF THIS PROBLEM AND IF IT OCCURRED AGAIN TO GIVE TOYOTA A CALL. THERE HAVE BEEN NO REPAIRS DONE TO THE VEHICLE. THE FAILURE MILEAGE WAS 2000 AND CURRENT MILEAGE WAS 8200. UPDATED 3/17/10 *CN THE CONSUMER STATED WHEN HE APPROACHED A STOP LIGHT AT THE TOP OF THE EXT RAMP, AT LESS THAN 35 MPH, HE ENCOUNTERED A BUMPY SURFACE IN THE ROAD AND THE BRAKES SEEMED TO SUDDENLY RELEASE AND THE VEHICLE ROLLED AHEAD. THE BRAKES SEEMED TO RE-ENGAGE MOMENTS LATER, PREVENTING THE VEHICLE FROM HITTING IN CAR AHEAD. IT WAS A MODERATE STOP ON DRY PAVEMENT WITH CONSISTENT PRESSURE ON THE BRAKE PEDAL. UPDATED 05/20/10

2010 TOYOTA PRIUS - BRAKING ISSUE ON SLIPPERY SERVICE - I FIND THE BRAKING DISTANCE REQUIRED TO STOP THE VEHICLE IS EXCESSIVE WHEN COMPARED TO MY PREVIOUS VEHICLE ON SLIPPERY SERVICES. THIS HAS RESULTED IN THE VEHICLE ROLLING FORWARD INTO INTERSECTIONS BEFORE COMING TO A STOP. I LIVE IN MN WHERE ROAD CONDITIONS CAN BECOME LESS THAN IDEAL. I DO NOT BELIEVE THAT I AM TRAVELING AT AN EXCESSIVE SPEED BUT I HAVE KNOW ADJUSTED MY DRIVING HABITS TO ACCOUNT FOR THE EXTRA DISTANCE REQUIRED TO STOP. *TR

I PURCHASED A 2010 TOYOTA PRIUS ON DEC. 23 2009 IN COLUMBUS OH, AND EXPERIENCED BRAKE PROBLEM TWICE. WHEN I WAS COMING OUT OF MY STREET TO MERGE TO A BIGGER STREET, I USED THE BRAKE TRYING TO STOP THE CAR. INSTEAD OF COMING TO A STOP, THE CAR JUMPED FORWARD. I HAD TO BRAKE IT AGAIN AND HARD TO STOP IT. I FELT AS IF THERE WAS AN INTERNAL ENERGY PUSHING THE CAR FORWARD. THIS HAPPENED TO ME TWICE. THE FIRST TIME WAS 3 WEEKS AGO, THE SECOND 2 WEEKS AGO. *TR

I OWN A 2010 TOYOTA PRIUS. SINCE PURCHASING IT IN AUGUST, I HAVE BEEN AWARE OF ODD, COMPLETELY REPRODUCIBLE BRAKING BEHAVIOR. I HAVE NOT REPORTED THE COMPLAINT UNTIL NOW BECAUSE I ASSUMED IT WAS SOMETHING NORMAL WITHIN THE OPERATION OF THE PRIUS, BUT WITH THE REPORT IN THE NEW YORK TIMES THAT JAPAN IS INVESTIGATING THE PRIUS BRAKING SYSTEM, I THOUGHT I SHOULD FILE A REPORT. I LIVE NEAR TRAIN TRACKS THAT HAVE A GRADE CROSSING IN THE MIDDLE OF A BLOCK. THE CROSSING ITSELF IS IN ANN ARBOR, MI, ON W. WILLIAM ST. BETWEEN S. ASHLEY ST AND S. 1ST ST. WHEN DRIVING WESTBOUND ON WILLIAM ST, ONE TRAVELS DOWNHILL AND ENCOUNTERS THE GRADE CROSSING NEAR THE BOTTOM OF THE HILL, ABOUT 20-30 FEET BEFORE AN INTERSECTION. EVERY TIME I CROSS THE TRAIN TRACKS AT THIS GRADE CROSSING--REGARDLESS OF WEATHER CONDITIONS--I NOTICE AN ALARMING LOSS OF BRAKING POWER THAT OCCURS EXCLUSIVELY WHEN CROSSING THE TRAIN TRACKS. AT FIRST I THOUGHT THIS WAS NORMAL, THAT PERHAPS THE CAR WAS JUST SLIPPING, BUT NOW IT SEEMS AS IF THIS REPRESENTS THE CONDITIONS THAT ARE UNDER INVESTIGATION IN JAPAN. THE PROBLEM IS 100% REPRODUCIBLE. TYPICAL TRAVEL SPEEDS ARE 15-30 MILES PER HOUR. THE BRAKING ACTION IS ONLY INTERRUPTED WHILE TRAVELING OVER THE BUMPY SURFACE OF THE RAIL TRACKS, AND THEN BRAKING ACTION IS RESTORED. HOWEVER, IF THERE ARE CARS QUEUED UP AT THE BOTTOM OF THE HILL AT THE INTERSECTION, IT OFTEN LEADS TO SHORT BRAKING TIMES AND HAS CAUSED CONCERN REGARDING THE EFFECTIVENESS OF THE BRAKES. I HAVE NOT SPOKEN TO

I OWN A 2010 TOYOTA PRIUS AND HAVE ENCOUNTERED THE SAME ISSUES WITH THE BRAKES THAT MANY OTHERS HAVE REPORTED. WHEN BRAKING (WHICH I DO OVER A LONGER THAN USUAL DISTANCE AND TIMEFRAME BECAUSE OF THE CAR'S ABILITY TO REGENERATE POWER WHILE BRAKING), THE BRAKE PEDAL DROPS AND THE CAR SUDDENLY ACCELERATES WHENEVER THE VEHICLE HITS A BUMP OR POTHOLE. THIS HAS HAPPENED MULTIPLE TIMES SINCE I TOOK POSSESSION OF THE VEHICLE IN JUNE 2009. NO ACCIDENTS OR INJURIES HAVE RESULTED, BUT I MUST BE PARTICULARLY CAUTIOUS OF ROAD CONDITIONS WHEN BRAKING BECAUSE THIS HAPPENS FREQUENTLY AND I AM CONCERNED ABOUT THE POSSIBILITY OF FUTURE ACCIDENTS OR PEDESTRIAN INCIDENTS. *TR

I HAVE BEEN DRIVING MY 2010 PRIUS FOR 4 MONTHS AND EVERYDAY I DRIVE OVER THIS ROAD NEAR MY WORK THAT'S NOT A TOTAL FLAT SURFACE WITH A BUMP, MY PRIUS JUST JERKS AND SLIDES FORWARD AND ACCELERATES FOR A SPLIT SECOND. THIS HAPPENS EVERY SINGLE DAY I DRIVE TO WORK OVER THIS BUMPY ROAD. IT WORRIES ME IF A PEDESTRIAN IS WALKING IN FRONT OF ME I AM NOT SURE IF I CAN PULL TO A COMPLETE STOP IN TIME. *TR

WE HAVE HAD SEVERAL INSTANCES OF BRAKE MALFUNCTION IN OUR 2010 PRIUS. WHEN BACKING OUT OF OUR GARAGE, ON 3 OCCASIONS, WHEN MY FOOT WAS JUST RESTING GENTLY OVER THE BRAKE, IT FELT AS THOUGH I WAS STOMPING ON THE BRAKE. IT DID THIS 4-5 TIMES WHERE IT LURCHED TO A STOP WHEN I WASN'T APPLYING IT BUT JUST RESTING MY FOOT ON IT AS I BACKED UP. I HAD AN INCIDENT WHERE I WAS ENTERING A CAR WASH AND WHEN I WENT OVER A BUMP INTO THE CAR WASH STALL, THE CAR LURCHED UNCONTROLLABLY FORWARD. I TRIED TO PUT THE CAR INTO NEUTRAL AND IT WOULDN'T STAY IN NEUTRAL BUT KEPT POPPING BACK INTO DRIVE AN LURCHING FORWARD.. ALSO, WE HAVE 3 INCIDENTS IN INCLEMENT WEATHER WHERE THE ANTI-LOCK BRAKES DID NOT WORK AT ALL OR DID NOT WORK CORRECTLY. ON A SNOWY DAY, I SLID RIGHT THROUGH AN INTERSECTION AND THE ANTI LOCK BRAKES DID NOT KICK IN NOR DID THE ANTI-LOCK BRAKE INDICATOR LIGHT COME ON. MY HUSBAND HAD AN INCIDENT WHERE IF FELT AS THOUGH THE ANTI-LOCK BRAKES FUNCTIONED ONLY ON ONE SIDE OF THE CAR, PROPELLING HIM STRAIGHT SIDEWAYS UPON BRAKING. WE FEEL VERY STRONGLY THAT THERE IS A PROBLEM WITH THIS MODEL OF PRIUS THAT POSES A SIGNIFICANT RISK TO OUR SAFETY. *TR

I PURCHASED A 2010 PRIUS IN JUNE, 2009. I HAVE NOTICED A "SURGE FORWARD" IF I APPLY THE BRAKES WHILE GOING OVER BUMPS LIKE RAILROAD TRACKS OR POTHOLES. THIS HAS HAPPENED REPEATEDLY. I JUST SAW A REPORT IN THE MEDIA THAT OTHERS HAVE HAD THE SAME PROBLEM. I WILL REPORT IT TO MY DEALER IN MADISON, WISCONSIN. *TR

2010 TOYOTA PRIUS FREQUENTLY ACCELERATES BRIEFLY WHEN BRAKING AFTER HITTING POTHOLE OR GOING OVER A BUMP. IN ADDITION, FREQUENTLY AT START UP, THE BRAKE PRESSURE IS EXTREMELY HIGH, AND THE SLIGHTEST RELEASE OF THE BRAKE CAUSES THE CAR TO LURCH RAPIDLY EITHER FORWARD OR BACK, DEPENDING UPON WHETHER IN DRIVE OR REVERSE. *TR

TOYOTA PRIUS 2010, SUDDEN SURGE OF POWER, WHEN SLOWING OR BRAKING TO COME TO A STOP. EXTREMELY DANGEROUS IN TRAFFIC OR WHEN PARKING. HAVE REPORTED TO TOYOTA, WHO CLAIMED NO KNOWLEDGE OF PRIUS'S HAVING THIS DEFAULT. ANOTHER SAID THIS WAS A COMMON FUNCTION OF THE HYBRIDS. RECENT SERVICE DEPT. CLAIMED CHECKED BUT FOUND NO EVIDENCE. THIS PROBLEM HAPPENS INTERMITTENTLY. BECAUSE WE KNOW OF THIS PROBLEM, ARE EXTRA CAUTIOUS. *TR

BRAKING POWER SUDDENLY GAVE OUT MOMENTARILY. THIS OCCURRED AT LOW SPEED. HOWEVER, I WAS APPROACHING A CROSSWALK WITH A PEDESTRIAN IN IT. IF FELT LIKE THE CAR LURCHED FORWARD. I READ THE ARTICLE IN THE NYT THIS MORNING WHICH NOTED THIS PROBLEM WITH THE PRIUS AND THIS DEFINITELY FITS MY SITUATION. IT DOES NOT HAPPEN FREQUENTLY (3 OR 4 TIMES AT MOST), BUT IT IS OBVIOUSLY A SAFETY ISSUE. I PURCHASED MY 2010 PRIUS NEW ON NOV. 3, 2009 FROM TOYOTA OF SEATTLE. I CONTACTED THE DEALER ABOUT THIS ISSUE A FEW DAYS AGO, BUT HAVE RECEIVED NO RESPONSE. *TR

EVERY TIME MY 2010 PRIUS GOES OVER A DIP IN THE ROAD WHILE BRAKING, THE CAR SEEMS TO ACCELERATE OR "LUNGE FORWARD." IT HAS HAPPENED SINCE I PURCHASED THE CAR IN MAY 2009. I HAVE NOT ASKED THE DEALERSHIP ABOUT THE ISSUE. *TR

WHILE I WAS DRIVING IN CITY TRAFFIC AND BRAKING FIRMLY AS TRAFFIC SLOWED, ONE OR BOTH OF MY RIGHT-SIDE TIRES PASSED OVER A MANHOLE COVER OR HIT A SHALLOW POTHOLE (THIS HAS HAPPENED SEVERAL TIMES). BRAKING EFFORT COMPLETELY STOPPED FOR A SECOND OR TWO -- THE CAR FELT AS IF IT WERE SURGING FORWARD, BUT THIS WAS PROBABLY JUST THE CHANGE FROM DECELERATION TO COASTING. BRAKING RESUMED, EITHER AUTOMATICALLY OR FOLLOWING INCREASED PRESSURE BY ME ON THE BRAKE PEDAL, I'M NOT SURE WHICH. NO COLLISION RESULTED, BUT ONE EASILY COULD HAVE IF I HAD BEEN FOLLOWING ANOTHER CAR EVEN A FEW FEET CLOSER THAN I WAS. *TR

I WAS DRIVING 2010 PRIUS TYPE III ON DOWNHILL. BECAUSE IT WAS DOWNHILL, I RELEASED GAS AND PREPARED TO PUSH BRAKE. THE ROAD WAS SLIGHTLY TURNED TO RIGHT SIDE AND THE SURFACE WAS A LITTLE BUMPY. WHEN THE CAR PASSED THE BUMPY SURFACE, IT SUDDENLY ACCELERATED EVEN THOUGH I DID NOT PUSH GAS. AS THE RESULT, I PUSHED THE BRAKE AND FORTUNATELY THE CAR STOPPED. HOWEVER, I DEFINITELY FELT THE CAR WAS ACCELERATED SUDDENLY AT HIGH SPEED(I DO NOT KNOW HOW MUCH IT WAS ACCELERATED). *TR

WHEN DRIVING MY 2010 TOYOTA PRIUS THE CAR HAS A TENDENCY TO ACCELERATE FORWARD AS I AM HITTING THE BRAKES. I HAVE NOTICED THIS IS USUALLY AROUND POTHOLES OR ANY OTHER BUMPS IN THE ROAD. IT HAPPENS PRETTY REGULARLY AND IT SCARES THE PANTS OFF ME; TO SAY THE LEAST. I HAVE FOUND NO RESPONSE FROM TOYOTA CONCERNING FIXING THIS PROBLEM AND AM WORRIED THAT WHEN SOMETHING BAD HAPPENS I'LL BE HELD RESPONSIBLE FOR THEIR MISTAKE. *TR

1. SMALL PATCH OF SNOW OR BUMP 2. LOSS OF BRAKES, 2 TIMES DUE TO SNOW AND 1 TIME DUE TO A BUMP, LOSS OF BRAKING FOR ABOUT 5 FEET ABOUT 20 FEET BEFORE A STOP SIGN. THERE IS NO PULSING (ABS) JUST A LOSS OF BRAKING. WHEN IT HAPPENS, I PUSH THE BRAKES HARDER AND AFTER ABOUT 5 FEET AT 5 MPH, I GET SUDDEN STRONG BRAKING. THE SNOW HAS ONLY BEEN ON THE RIGHT FRONT TIRE. THIS IS NOT JUST LOSS OF TRACTION BECAUSE I DON'T HEAR THE NOISE ASSOCIATED WITH THAT. 3. NONE, READ OTHER SIMILAR ACCOUNTS THAT THE DEAL IS CALLING NORMAL. *TR

WE LIVE IN CHICAGO AND OWN A 2010 PRIUS. WE ALSO HAVE EXPERIENCED THE ACCELERATION (FORWARD SURGE) UPON BRAKING ON UNEVEN TERRAIN REPORTED BY OTHER OWNERS. NO ACCIDENT, BUT IT HAPPENS OFTEN ON OUR CITY STREETS AND IT IS A LITTLE UNNERVING. THE LAST TIME IT HAPPENED WAS YESTERDAY. *TR

I WAS DRIVING MY 2010 PRIUS AND APPROACHED A STOP SIGN AT AN INTERSECTION ON A LOCAL ROAD. (AS I APPROACHED THE INTERSECTION I WAS PROBABLY DRIVING ABOUT 20 MPH OR LESS). AFTER I HIT THE BRAKES AND HAD BEEN DECELERATING FOR A VERY BRIEF PERIOD, I WENT OVER A POTHOLE OR SOME SIMILAR PROTRUSION. AT THAT POINT, MY CAR LURCHED FORWARD, ALMOST HITTING ANOTHER CAR. THAT CAR HAD BEEN ABOUT HALF CAR LENGTH IN FRONT OF ME WHEN I HIT THE POTHOLE. *TR

I BOUGHT A 2010 TOYOTA PRIUS ON DEC. ON 12/21/2009, AND HAVE NOTICED ON AT LEAST 4 OCCASIONS THAT WHEN I BRAKE ON TOP OF A BUMP IN THE ROAD, THE CAR ACTUALLY LURCHES FORWARD, INSTEAD OF SLOWING DOWN AND STOPPING. I THOUGHT IT WAS JUST ME, BUT THEN I HEARD A STORY ABOUT IT ON NPR, AND NOW FEEL THAT THIS PROBLEM HAS BEEN CONFIRMED BY OTHERS. I HAVE BEEN LUCKY THAT ON THE OCCASIONS WHEN IT HAS HAPPENED, THERE HAS NOT BEEN A CAR IN FRONT OF ME, OR I MIGHT HAVE HIT THEM FROM BEHIND. *TR

WHILE DRIVING OUR 2010 PRIUS ON OR AROUND JAN 23RD AT AROUND 2:30PM CST, SAW A POT HOLE AHEAD AND STARTED BRAKING. THE LEFT FRONT TIRE WENT OVER THE POT HOLE BUT THE BRAKES SKIPPED AND THE VEHICLE DIDN'T STOP AND CONTINUED TO MOVE AHEAD WITH THE SAME SPEED. FORTUNATELY, NO ONE WAS THERE IN FRONT. RE-APPLIED THE BRAKES AGAIN QUICKLY TO BRING THE VEHICLE TO A STOP. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHENEVER THE CONTACT ATTEMPTS TO BRAKE TRAVELING OVER A ROUGH TERRAIN AT A LOW SPEED THE CONTACT NOTICED THAT THE BRAKES WILL SUDDENLY DISENGAGE AND THEN CORRECT ITSELF. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALERSHIP AND THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 5600.

ALMOST 100% OF THE TIME WHEN APPROACHING THE INTERSECTION OF 20TH & BROADWAY (SANTA MONICA, CA) FROM THE EAST SO I CAN TURN RIGHT TO HEAD NORTH ON 20TH, MY 2010 TOYOTA PRIUS SURGES FORWARD WHEN I HIT A BUMP/POTHOLE IN THE ROAD WHILE BRAKING TO A STOP. THE SURGE IS ENOUGH TO LAUNCH THE CAR FORWARD INTO THE CROSSWALK, SO IF SOMEONE WERE CROSSING THE STREET IT IS POSSIBLE THE CAR MAY HIT THEM. I HAVEN'T DONE ANYTHING TO CORRECT THE FAILURE, BUT I NEED TO SEE THE DEALERSHIP ABOUT THE PROBLEM. *TR

2010 TOYOTA PRIUS ANTI-LOCK BRAKES FAIL TO STOP SKIDDING ON MINOR ICE. *TR

2010 TOYOTA PRIUS - ODD BRAKING BEHAVIOR. ON A NUMBER OF OCCASIONS, WHEN THE VEHICLE IS COMPLETELY STOPPED AND THE WHEELS ARE NOT TURNING, WHEN I PRESS ON THE BRAKE PEDAL, THE ORANGE "SKID WARNING" INDICATOR ON THE INSTRUMENT CLUSTER TURNS ON. SOMETHING IS WRONG WHEN I GET SUCH A WARNING, AS THE VEHICLE IS NOT MOVING, AND CERTAINLY NOT SKIDDING. *TR

I HAVE A 2010 TOYOTA PRIUS IV AND I HAVE EXPERIENCED THE REPORTED PROBLEM WITH THE BRAKING; NAMELY WITH THE BRAKE APPLIED AND I RUNNING OVER A ROUGH SPOT OR BUMP IN THE ROAD ( A GOOD EXAMPLE IS BRAKING WHEN GOING OVER ROUGH RAILROAD TRACKS) YOU FEEL A MOMENTARY SURGE OR ACCELERATION. I HAVE NOTED THIS PROBLEM QUIT A FEW TIMES SINCE THE CAR WAS NEW (CAR HAS BEEN DRIVEN APPROX. 5000 MILES). *TR

I THOUGHT THAT IT WAS JUST ME BUT WHEN I HEARD OTHERS COMPLAINING ABOUT THE BRAKES ON THE NEW 2010 PRIUS I CONFIRMED WHAT I HAVE BEEN EXPERIENCING. WHENEVER I BEGIN TO BRAKE AND EITHER (A) HIT A BUMP OR (B) BEGIN A TURN, THE CAR JUMPS OR LURCHES AS IF LOSING TRACTION FOR AN OVERLY EXCESSIVE AMOUNT OF TIME LEADING TO A SHORT BUT SIGNIFICANT LOSS OF CONTROL. *TR

I OWN A 2010 PRIUS, AND HAVE EXPERIENCED AN ACCELERATION ISSUE ON ABOUT 3-4 OCCASIONS SINCE PURCHASING THE VEHICLE IN AUGUST OF 2009. THE ISSUE I HAD WAS PERFECTLY DESCRIBED IN A RECENT ON-LINE ARTICLE FROM MONEY.CNN.COM ON FEB 3. HERE IS THE QUOTE - "THE COMPLAINTS RECEIVED VIA OUR DEALERS CENTER AROUND WHEN DRIVERS ARE ON A BUMPY ROAD OR FROZEN SURFACE," A TOYOTA MOTOR CORP. SPOKESMAN IN JAPAN, SAID. "THE DRIVER STEPS ON THE BRAKE AND THEY DO NOT GET AS FULL OF A BRAKING FEEL AS EXPECTED." THIS IS EXACTLY WHAT I'VE EXPERIENCED, AND IT ALSO SEEMS TO POSSIBLY BE RELATED TO THE SHIFT FROM GAS TO ELECTRIC WHICH OCCURS WHEN SLOWING DOWN. AFTER BRAKING, THERE IS A SUDDEN, BRIEF SURGE OF ACCELERATION. I HAVE NOT BROUGHT THIS INTO THE DEALER, BUT PLAN TO SOON. *TR

BRAKES LOCKED UP WHEN GENTLY PUSHING ON PEDAL AT LOW SPEEDS IN FORWARD AND REVERSE, ANTI LOCK BRAKES ENGAGE WHILE STOPPED IF YOUR FOOT WIGGLES ON BRAKE PEDAL, BRAKES DO NOT ENGAGE STRONG IF YOU HIT A SMALL BUMP WHILE BRAKING CAUSING YOU TO NOT STOP ON TARGET AND ANTI LOCK BRAKE SYMBOL BRIEFLY FLASHES ON AT THE SAME TIME. *TR

I HAVE A 2010 TOYOTA PRIUS. APPROXIMATELY 10 TIMES SINCE I BOUGHT THE CAR IN JULY 2009 IT HAS JOLTED FORWARD WHILE I AM APPLYING THE BRAKES WHEN I DRIVE OVER A POTHOLE OR BUMP IN THE ROAD. *TR

MY 2010 TOYOTA PRIUS HAS A RECURRING PROBLEM WITH ITS BRAKES. ON MULTIPLE OCCASIONS, WHEN I AM BRAKING AND HIT A POTHOLE OR OTHER UNEVEN SURFACE THE CAR LURCHES OR SLIPS FORWARD AND THE BRAKING ACTION STOPS. THIS HAS HAPPENED TO BOTH ME AND MY WIFE WHILE DRIVING THE CAR. THE FEELING WHILE DRIVING THE CAR IS THAT THE CAR IS MOMENTARILY OUT-OF-CONTROL AND THAT THE CAR WILL NOT STOP IN TIME. *TR

BRAKES DO NOT WORK CORRECTLY AFTER HITTING BUMPS IN CERTAIN CONDITIONS. *TR

VEHICLE OCCASIONALLY JUMPS AHEAD DURING BRAKING. MOST LIKELY TO HAPPEN WHEN STOPPING ON A DOWNHILL GRADE AT MODERATE SPEED (UNDER 35 MPH). BRAKES ENGAGE AGAIN AFTER BRIEF ACCELERATION AND CAR SO FAR HAS COME SAFELY TO A STOP. DATE BELOW IS APPROXIMATE DATE OF FIRST OCCURRENCE. *TR

THE BRAKE OF MY CAR WAS MALFUNCTION. WHILE BREAKING, THE CAR SLOWED DOWN INITIALLY. HOWEVER, BEFORE THE CAR TOTALLY STOPPED, IT ACCELERATED SUDDENLY AND SPONTANEOUSLY FOR SEVERAL SECONDS. THIS CONDITION HAPPENED FOR 4 TIMES WITHIN 2 MONTHS. THERE WAS NO ICE ON THE ROAD AND THE ROAD WAS NOT BUMPING EITHER. *TR

MY 2010 TOYOTA PRIUS ACCELERATES OVER POTHOLES AND BUMPS IN THE ROAD WHEN I'M PRESSING ON THE BRAKE. EVEN IF I AM BRAKING FOR A FEW SECONDS, AS SOON AS I GET TO THE POTHOLE, IT PUSHES FORWARD. THIS HAPPENS TO ME AT LEAST ONCE A DAY AND SOMETIMES MULTIPLE TIMES A DAY. I HAVE ONLY BEEN DRIVING THE CAR FOR 5 WEEKS AND HAVE NOTICED THIS ISSUE SINCE DAY ONE. *TR

MY 2010 PRIUS HAS TWICE HAD A BRIEF MOMENTARY LOSS OF BRAKING IN SLOW SPEED. BOTH TIMES THIS OCCURRED WHEN TRYING TO STOP FOR A STOP SIGN IN A RESIDENTIAL AREA WITH LOW SPEED AND ON ICY/SNOWY SURFACE. THE VEHICLE STOPPED 5 FEET OR SO PAST THE ORIGINALLY INTENDED POINT OF STOPPING. *TR

BRAKE NOT RESPONDING WHEN APPLIED. *TR

I OWN A 2010 TOYOTA PRIUS, 3RD GENERATION. WHEN I AM BRAKING AND HIT A POTHOLE OR A MANHOLE COVER, THE CAR SURGES FORWARD. I TOOK IT TO THE DEALERSHIP TODAY AND THEY CHECKED THE CAR AND SAID THEY COULDN'T FIND ANYTHING WRONG WITH IT. THEY ALSO SAID THEY HAD NO KNOWLEDGE OF ANY KIND OF BRAKING OR SURGING PROBLEMS WITH THIS VEHICLE. OUR DEALER WAS EASTERN SHORE TOYOTA IN DAPHNE, AL. THIS HAS HAPPENED APPROXIMATELY 6 DIFFERENT TIMES SINCE WE BOUGHT THE CAR IN 2009. IT STARTED TO OCCUR APPROXIMATELY IN JULY 2009, WITH THE MOST RECENT EPISODE IN JANUARY 2010. *TR
