2010 Toyota Prius complaints

2010 PRIUS SURGES WHEN A BUMP IS HIT WHILE BRAKING. THIS IS FAIRLY REPEATABLE AND CAN OCCUR AS MUCH AS ONCE A DAY. WE HAVE NOT TAKEN BACK TO THE DEALER, BECAUSE BEING IN THE AUTOMOTIVE ELECTRONICS INDUSTRY, I AM CERTAIN IT IS A SOFTWARE BUG AND THAT THE DEALER WILL NOT FIND ANYTHING WRONG OR KNOW HOW TO FIX IT. *TR

I PURCHASED A NEW 3RD GENERATION TOYOTA PRIUS IN AUGUST OF 2009. I HAVE NOTICED TWO INCIDENTS WHERE MY BRAKES DID NOT RESPOND PROPERLY IMMEDIATELY AFTER PASSING OVER DISTINCT POTHOLES. THEY HAD WAY TOO MUCH "GIVE." ON THE SECOND PUMP OF THE BRAKES, THE FULL BRAKING POWER APPEARED TO BE RESTORED. *TR

EARLY DEC. 2009 I HIT A POTHOLE AND FELT MY BRAKES FAIL FOR A SECOND THEN GRAB AGAIN. AT FIRST I THOUGHT THIS WAS BLACK ICE BUT IT HAPPENED AGAIN A WEEK OR SO LATER AND THEN AGAIN TOWARD THE END OF DEC. 2009. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 5 MPH DEPRESSING THE BRAKE PEDAL OVER A SPEED BUMP, THE VEHICLE LUNGED FORWARD AND THE VEHICLE PROCEEDED TO ACCELERATE. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT THERE WAS A COMPUTER GLICH THAT CAUSED THE FAILURE TO OCCUR. THE FAILURE MILEAGE WAS 5,000.

I HAVE A 2010 PRIUS IV AND CAN CERTAINLY SAY THAT I HAVE FELT SEVERAL TIMES A BIT OF "BRAKE-LOSS" ON THIS VEHICLE. BY THAT, I MEAN THAT AT TIMES I HAVE TO PUSH DOWN MUCH HARDER ON THE BRAKE PEDAL TO COME TO A STOP. THIS HAPPENS AT RANDOM TIMES AND CAUSES ME A BIT OF NERVOUSNESS AS A FEW TIMES I CAME CLOSE TO HITTING THE CAR IN FRONT OF ME. THIS TENDS TO HAPPEN AS I AM COMING TO A STOP, NOT DURING HIGH-SPEED BRAKING. I WOULD ESTIMATE THAT THIS HAS HAPPENED AT LEAST 10 TIMES DURING 4,000 MILES OF DRIVING. *TR

2010 PRIUS BRAKE FAILURES AT LEAST 4 TIMES IN PAST 6 MONTHS AFTER HITTING POTHOLE OR ICE ON ROAD AT ABOUT 30MPH OR LESS; BRAKE PEDAL GOES TO FLOOR AND CAR SORT OF SHIMMIES. *TR

BRAKES SUDDENLY LURCH, ESPECIALLY WHEN THERE IS SNOW OR UNEVEN SURFACE (POTHOLE), FIRST NOT CATCHING AND THEN CAUSING BRIEF MORE SUDDEN BRAKING. THIS IS AS IF THE ABS IS NOT WORKING PROPERLY. THIS HAS HAPPENED ABOUT 3-4 TIMES SINCE PURCHASE OF CAR ABOUT 12/5/09. *TR

BRAKE PROBLEM WITH MY 2010 TOYOTA PRIUS. HAS BEEN HAPPENING SINCE I PURCHASED THE CAR BUT DIDN'T REALIZE IT WAS SUCH A WIDE-SPREAD PROBLEM. ONE OUT OF EVERY 500 TIMES I PUSH ON THE BRAKE PEDAL, THE CAR WILL FIRST LUNGE FORWARD FOR A SPLIT SECOND AND THEN BEGIN TO DECELERATE. IT IS A VERY CLEAR JOLT WHEN THE BRAKE PEDAL IS FIRST DEPRESSED. *TR

I AM EXPERIENCING A LOSS OF BRAKING POWER, DURING SLOWER SPEED STOPS OR ATTEMPTS TO SLOW DOWN. THE PROBLEM OCCURS AT GENERALLY LESS THAN 20 MPH. I APPLY THE BRAKES AND THE CAR BEGINS TO SLOW, HOWEVER, IF I HIT A BUMP OR POTHOLE, THE CAR FEELS LIKE IT IS ACCELERATING AND/OR LOSING BRAKING POWER, DESPITE MY FOOT REMAINING ON THE BRAKE PEDAL. I AM ABLE TO REGAIN BRAKING BY FURTHER PRESSING THE BRAKE PEDAL. THE ACCELERATION/LOSS OF BRAKING FEELS LIKE IT'S COMING FROM THE REAR WHEELS OF THE CAR AND AT LEAST IN MY EXPERIENCE FEELS LIKE THE PROBLEM ONLY OCCURS WHEN THE REAR WHEELS GO OVER THE BUMP OR INTO THE POTHOLE. A SIMILAR LOSS OF BRAKING HAS NOT OCCURRED WHEN THE FRONT WHEELS GO OVER BUMPS OR POTHOLES AT LOWER SPEEDS. THE BRAKING LAPSE CAUSES MY STOPPING DISTANCE TO BE LENGTHENED. THIS LOSS OF BRAKING POWER HAS OCCURRED SEVERAL TIMES SINCE I BOUGHT MY CAR IN JULY 2009. I FIRST NOTICED THE PROBLEM IN THE FALL OF 2009 AND IT MOST RECENTLY HAPPENED THIS PAST MONDAY (2/1/2010). THE PROBLEM DOES NOT APPEAR TO OCCUR AT HIGHER SPEEDS, SUCH AS ON A HIGHWAY OR MAIN ROAD. I WAS NOT CARRYING ANY CARGO OR ADDITIONAL WEIGHT IN THE VEHICLE DURING ANY OF THE INCIDENTS. *TR

2010 TOYOTA PRIUS ACCELERATES FOR A SECOND WHEN I HIT THE BRAKES WHEN I AM PASSING OVER POTHOLES OR ICE. IT HAS HAPPENED WELLOVER 10 TIMES. *TR

SLOWING DOWN WHILE APPROACHING A LEFT TURN LANE, HIT A POTHOLE AND LOST BRAKING POWER FOR ABOUT 0.5S. *TR

PURCHASE 2010 PRIUS IN NOV 2009. ON SMOOTH HIGHWAY ( NY LIE ) TRAVELING 70MPH TO PASS A CAR. GENTLY APPLIED BRAKE TO SLOW DOWN BUT THE PRIUS LURCHED FORWARD FOR 2-3 SECONDS ( 200 - 300 FEET ). ALMOST HIT CAR IN FRONT OF ME. *TR

2010 PRIUS: WHEN APPLYING BRAKING PRESSURE ON SLIPPERY PAVEMENT THERE IS A NOTICEABLE LAG BEFORE BRAKING ACTION OCCURS. THIS CAN ALSO OCCUR ON GRAVEL ROADS ON WASHBOARD SURFACES. *TR

WHEN MY 2010 PRIUS GOES OVER A POTHOLE IT SURGES AND BRAKES AREN'T RESPONSIVE ENOUGH TO PREVENT HITTING THE CAR IN FRONT OF ME. SO FAR I HAVEN'T HIT ANY BODY OR ANOTHER VEHICLE.*TR

SINCE BUYING A 2010 PRIUS IN JUNE, I HAVE EXPERIENCED THREE "SURGING" EVENTS WHILE BRAKING AS I DECENDED HILLS. TWO INVOLVED SITUATIONS INVOLVING HITTING ROAD DEPRESSIONS, WHICH ALMOST CAUSED ME TO GO THROUGH TRAFFIC LIGHTS, ONE INVOLVED A ROAD COVERED WITH 1-2 INCHES OF SNOW, WHICH ALMOST PROPELLED ME INTO ONCOMING TRAFFIC AT A STOP SIGN. ALL SITUATIONS OCCURRED AS I WAS DESCENDING HILLS AND SLOWING SPEED BY BRAKING. THE FIRST INCIDENT OCCURRED IN THE SUMMER, THE LAST YESTERDAY. I REPORTED THIS TO MY DEALER, WHO HAD NO INFORMATION ON IT FROM TOYOTA, BUT ADVISED ME TO FILE A COMPLAINT WITH TOYOTA, WHICH I DID, CASE #1002106542. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED AS HE WAS STOPPING HIS VEHICLE, HE HIT A BUMP IN THE ROAD WHILE DEPRESSING THE BRAKE THE VEHICLE LURCHED FORWARD AND ACCELERATED. THE VEHICLE WAS TAKEN TO THE DEALER AND CONTACT WAS TOLD THIS WAS NORMAL AND IT IS THE ELECTRICAL ENGINE SWITCHING TO THE GAS ENGINE. THE CONTACT STATED THAT THIS IS A CONTINUOUS PROBLEM WHILE STOPPING THE VEHICLE. THE FAILURE MILEAGE WAS 8,800.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHENEVER SHE ATTEMPTS TO STOP ON AN UNEVEN ROAD, THE BRAKES FAIL TO STOP THE VEHICLE. WHENEVER THE FAILURE OCCURRED THE SPEED VARIES. THE VEHICLE ALSO BRIEFLY LUNGED FORWARD AND ACCELERATED. THE BRAKES SQUEAK CONTINUOUSLY WHEN THE VEHICLE IS DRIVEN. THE VEHICLE WAS TAKEN TO THE DEALER WHO CONFIRMED THAT THE VEHICLE WAS FUNCTIONING NORMALLY SINCE IT HAS AN ELECTRICAL ENGINE COMBINED WITH A GASOLINE ENGINE. THE FAILURE MILEAGE WAS 18,000.

I PURCHASED A 2010 PRIUS IN AUGUST 2009. IT SHOWS NO EVIDENCE OF AN ANTI-LOCK BRAKING SYSTEM. I REPORTED THIS TO THE TAYLOR TOYOTA OF ALEXANDRIA IN OCTOBER WHO TOLD ME THAT THEY HAD NOT HEARD OF THE PROBLEM AND THEY DID NOTHING. ADDITIONALLY, THE AVID FACTORY TIRES ON THE CAR ARE NOT EFFECTIVE ON WET PAVEMENT; THEY SKID. AGAIN, I REPORTED THIS TO THE DEALER AND AGAIN THEY TOLD ME THEY HAD NOT HEARD OF A PROBLEM BUT REFERRED ME TO THEIR PARTS DEPARTMENT TO BUY NEW TIRES. FINALLY, WHEN I ENGAGE CRUISE CONTROL, THE CAR SURGES FORWARD IN SPEED UNTIL I DEPRESS THE BRAKE. I STOPPED USING THE CRUISE CONTROL. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY BETWEEN 35-40 MPH AND ENCOUNTERED A BUMP IN THE ROADWAY. THERE WAS PRESSURE APPLIED TO THE BRAKE PEDAL, FOLLOWED BY NO POWER RESPONSE FOR A FEW SECONDS. THE VEHICLE RESUMED TO NORMAL OPERATION. IN ADDITION, THERE WAS AN EXCESSIVE KNOCKING NOISE COMING FROM THE ENGINE DURING THE START UP WHICH OCCURRED ON TWO SEPARATE OCCASIONS. THE VEHICLE HAD NOT BEEN INSPECTED FOR THE MALFUNCTION. THE FAILURE MILEAGE WAS 15,000.

AS I WAS APPLYING MY BRAKE MY CAR WENT OVER A BUMP, MOST LIKELY A MAN HOLE COVER, FOR A SPLIT SECOND I FELT LIKE THE BRAKES STOPPED WORKING, THEN IT WENT BACK TO NORMAL. *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

TOYOTA PRIUS ACCELERATES AFTER HITTING POTHOLES. CANNOT SLOW VEHICLE AS BRAKES DON'T WORK IMMEDIATELY. THIS PROBLEMS IS RANDOM AND DOES NOT OCCUR ON A REGULAR BASIS. *TR

WHEN CAREFULLY BRAKING MY 2010 TOYOTA PRIUS AT LOW SPEEDS (40 MPH AND LOWER), A SMALL DIP OR BUMP IN THE ROAD WILL CAUSE THE CAR TO RELEASE THE BRAKES AND THE EFFECT IS A SUDDEN ACCELERATION OR RELEASE OF THE BRAKING SYSTEM WHICH LASTS APPROXIMATELY 1 SECOND. THIS FAILURE IN THE VEHICLE IS SEEMINGLY UNRELATED TO A MECHANICAL ISSUE AND FEELS MORE LIKE AN ELECTRICAL ISSUE, SINCE THERE IS NO STIFF PEDAL OR OBSTRUCTION NEAR THE PEDAL. THE FAILURE OCCURS ON A SEMI-REGULAR BASIS. I TOOK THE CAR INTO THE TOYOTA DEALERSHIP WHERE I BOUGHT MY VEHICLE, SUBURBAN TOYOTA LOCATED IN TROY, MICHIGAN, AND REPORTED THE PROBLEM, APPROXIMATELY 4 MONTHS FROM THE TIME I BOUGHT THE CAR (JUNE 2009). THE MECHANICS KEPT THE VEHICLE OVER NIGHT. THE DEALER THEN REPORTED THAT THEY DID EXPERIENCE THE PROBLEM WHEN TESTING THE VEHICLE AND SAID IT WAS RELATED TO THE ANTI-LOCK BRAKING SYSTEM AND THAT THE CAR WAS DESIGNED TO MOVE AROUND AN OBJECT RATHER THAN HEAVY BRAKING. THEY DID NOTHING TO FIX THE CAR. THE PROBLEM PERSISTS AND I HAVE HEARD SIMILAR COMPLAINTS OF UNINTENDED ACCELERATION, BOTH WHEN BRAKING AND COASTING. I AM CONCERNED I WILL AT SOME POINT HIT A CAR THAT IS TOO CLOSE IN FRONT OF ME. *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 WHILE BRAKING, IF THE CAR DRIVE OVER A BUMP, THE CAR ACCELERATES. TO STOP THE CAR, THE BRAKES MUST BE PRESSED TO THE FLOOR BOARD TO STOP AND AVOID AN ACCIDENT. THE CAR HAS HAD THIS PROBLEM SINCE PURCHASED 8/2009. *TR

INCIDENT 1: WEATHER CONDITION - COLD AND DRY. ROAD CONDITION - BUMPY, WASHBOARD JUST BEFORE A STOP SIGN PRESSED ON BRAKE PEDAL, CAR SLOWED UNTIL WASHBOARD SECTION OF ROAD CAME UP, THEN BRAKE SEEMED TO DISAPPEAR BRIEFLY AND THEN CAR STOPPED. VERY FRIGHTENING. IF THERE WAS SOMEONE IN FRONT OF ME I WOULD HAVE HIT THEM. NO INJURIES, NO CRASH. INCIDENT 2 WEATHER CONDITION: SNOW, SNOW FALLING, 1" ON ROADWAY. LOCATION: PARKING LOT. CAME AROUND CORNER VERY SLOWLY DUE TO WEATHER CONDITIONS. ABS CAME ON EARLY WHEN APPLYING BRAKES AND THE BRAKES APPEARED NOT TO WORK FOR A BRIEF TIME AND THEN THEY WORKED BUT STOP WAS MUCH LONGER THAN IT SHOULD HAVE BEEN. I ALMOST HIT A WALL. *TR

THIS COMPLAINT IS REGARDING MY 2010 TOYOTA PRIUS WHICH I PURCHASED IN AUGUST OF 2009. BEFORE MY FIRST OIL CHANGE WAS DUE I HAD NOTICED THE VEHICLE'S TENDENCY TO NOT RESPOND INSTANTLY TO MY STEPPING ON THE BRAKE, AND THEN LURCH FORWARD WHEN THE BRAKES DID ENGAGE. MY BRAKES ALSO SQUEAL EVEN WHEN THE WEATHER IS DRY. I REPORTED THIS TO THE DEALER WHEN I TOOK IT IN FOR TIRE ROTATION AND OIL CHANGE. OF COURSE THEY TOLD ME THE MOMENTARY PAUSE OF THE BRAKES "WAS NORMAL" AND THEY DID NOT HEAR THE BRAKES SQUEAL. WELL MY VEHICLE IS STILL DOING BOTH OF THESE THINGS AND IT SEEMS I AM NOT THE ONLY ONE WITH A CONCERN REGARDING THE BRAKES. PLEASE ADD MY VEHICLE TO THE LIST OF OWNERS WHO ARE WORRIED ABOUT THESE BRAKES. I HAVE BEEN DRIVING FOR 40 YEARS, EVERY MAKE AND MODEL, INCLUDING TRACTORS ON THE FARM AND I KNOW THERE IS A PROBLEM NO MATTER WHAT THAT DEALERSHIP OR TOYOTA SAYS. *TR

01/13/2010 - I WENT TO THE SERVICE DEPT AT TOYOTA OF WALLINGFORD TO COMPLAIN ABOUT THE LOSS OF BRAKES IN A NEW 2010 TOYOTA PRIUS WHILE DRIVING OVER UNEVEN GROUND. I HAD OWNED THE CAR ONE MONTH WITH 1500 MILES ON THE ODOMETER. THE LOSS OF CONTROL OF THE CAR IS TERRIFYING BECAUSE THE CAR SEEMS TO ACCELERATE FORWARD. THE SERVICE ATTENDANT WAS AWARE OF THE ISSUE AND DESCRIBED THE SITUATION. HE TOOK THE CAR ON A TEST DRIVE. HE ASSURED ME IT WAS NOT A SAFETY ISSUE. *TR

I OWN A 2010 TOYOTA PRIUS. WHEN I APPLY THE BRAKES, THE CAR JERKS FORWARD BEFORE STOPPING. I AM VERY CONCERNED ABOUT THE SOFTWARE PROBLEM IN THE ABS SYSTEM AND WANT THE NHTSA TO DEMAND THAT TOYOTA FIX THE 2010 PRIUS BRAKES. THE PROBLEM WITH THE JERKING BRAKES HAPPENS FREQUENTLY, AND HAS HAPPENED AT LEAST 40 TIMES OVER THE PAST 4 MONTHS. *TR

I OWN A 2010 PRIUS AND PURCHASED IN 5/2009. I SIMPLY WANT TO CONFIRM THAT THE BRAKES SEEM DISENGAGED WHEN GOING OVER BUMPS AND STUTTER BUMPS, AND THIS IS SHORT LIVED. FOR ME, THIS WAS NOT ENOUGH OF AN ISSUE TO INITIALLY COMPLAIN. HOWEVER, I COULD SEE THAT IF THERE WAS A SERIES OF STUTTER BUMPS, I MIGHT LOSE BRAKING ALTOGETHER. *TR

WHEN DRIVING MY PRIUS, I HAVE NOTICED THE FEELING OF BEING THROWN FORWARD FOR A SPLIT SECOND AFTER I HAVE APPLIED THE BRAKES WHEN ON AN UNEVEN SURFACE, IE A GRATE IN THE ROAD. THIS OCCURS NEARLY EVERYTIME I ROUND A CORNER BY MY APARTMENT IN WHICH I AM FORCED TO BRAKE AS I GO ACROSS A METAL PLATE IN THE ROAD. *TR

I PURCHASED MY 2010 PRIUS ON AUGUST 4TH, 2009 AND ALMOST IMMEDIATELY NOTICED ISSUES WITH THE BRAKES. I DISTINCTLY REMEMBER DRIVING IN THE CAR ON THIS DATE WITH MY WIFE AS WE WERE ON OUR WAY BACK FROM HER ULTRASOUND. I JUST GOT OFF THE HIGHWAY AND THERE WAS A RED LIGHT AHEAD WITH SEVERAL CARS STOPPED AT IT. I APPLIED THE BRAKES SLOWLY AND STEADILY, AS I NORMALLY DO, BRAKING WITH PLENTY OF TIME TO STOP. AS I APPROACHED THE LAST CAR AT THE STOP LIGHT I ENCOUNTERED A POT HOLE AND THE BRAKES DISENGAGED. I COULD FEEL THE CAR WAS NO LONGER DECELERATING. I HAD TO SLAM ON THE BRAKES AND BARELY AVOIDED SLAMMING IN TO THE CAR AHEAD OF ME, STOPPING WITH LITERALLY AN INCH BETWEEN OUR BUMPERS. SINCE THAT DATE I HAVE ENCOUNTERED THIS EXACT SAME SCENARIO SEVERAL TIMES A MONTH AND HAVE COME CLOSE TO AN ACCIDENT 2 TO 3 TIMES. *TR

I HAVE NOTED A BRAKING ISSUE WITH MY 2010 TOYOTA PRIUS V EQUIPPED WITH A NAVIGATION SYSTEM. THE BRAKES DO STOP THE CAR, BUT SEEM TO DELAY STOPPING THE CAR AFTER THE APPLYING THE BRAKE. THE CAR WAS PURCHASED IN AUGUST 2009. I HAVE NOT BEEN CONTACTED BY TOYOTA. *TR

I HAVE HAD 3 INCIDENTS IN THE LAST 8 MONTHS WITH MY 2010 PRIUS WHERE WHEN BRAKING THERE IS A SLIGHT ACCELERATION BEFORE THE BRAKES GET IN. IN ALL CASES I WAS DRIVING AT SLOW SPEEDS (30MPH) ON A FLAT SURFACE. IT EVENTUALLY BRAKES OK, BUT IT IS VERY NERVE WRACKING. *TR

OUR 2010 PRIUS BOUGHT IN OCTOBER 2009 FAILED TO STOP IN TIME AND GOT INTO AN ACCIDENT IN NOVEMBER 2009. WE HAD SUSPECTED A BRAKE ISSUE SINCE WE BOUGHT THE CAR BUT WERE NOT CONCERNED UNTIL NOW THAT TOYOTA HAS ACKNOWLEDGED THIS ISSUE WITH BRAKES, WE WANT TOYOTA TO FIX THIS ISSUE AND ISSUE A RECALL. *TR

BRAKE PROBLEM WITH 2010 TOYOTA PRIUS. *TR

WHEN I GO OVER A BUMP OR HIT A SIGNIFICANT POTHOLE, THE ANTI-LOCK BRAKING SYSTEM ON MY 2010 TOYOTA PRIUS SEEMS TO FREEZE UP. I AM UNABLE TO USE THE BRAKES PROPERLY AND IT FEELS LIKE I DO NOT HAVE CONTROL OF MY CAR FOR A COUPLE OF SECONDS. FORTUNATELY, I HAVE NOT HAD AN ACCIDENT AS A RESULT BUT I AM VERY CONCERNED ABOUT THIS. *TR

ON AT LEAST TWO OCCASIONS, I HAVE HAD UNEVEN, JERKY ACCELERATION FROM MY 2010 TOYOTA PRIUS. ACCELERATION WAS FROM A STAND STILL AND WAS AT LOW RATES OF SPEED. BOTH INSTANCES HAVE OCCURRED WHEN THE VEHICLE WAS COLD, BUT THE AMBIENT AIR TEMPERATURE WAS PROBABLY ABOVE 30 DEGREES. *TR

ON FIVE SEPARATE OCCASIONS, WHEN APPLYING THE BRAKE TO STOP AT AN INTERSECTION THE CAR WOULD INITIALLY BEGIN TO SLOW DOWN AND THEN, WHILE THE BRAKE IS STILL BEING APPLIED FEEL LIKE IT SKIPPED OR ACCELERATED FOR ANOTHER 10-15 FEET BEFORE STOPPING. THE TERM SCARY COULD BE APPLIED TO THE SUDDEN FEELING OF HAVING THE CAR ACCELERATE WHEN THE BRAKES ARE BEING APPLIED. *TR

SOMETIMES WHEN OUR 2010 PRIUS HITS A POTHOLE, ICE CHUNK OR OTHER BUMPY ROAD CONDITIONS WE WILL VERY TEMPORARILY LOSE BRAKING POWER. IT SEEMS TO OCCUR AS THE TRACTION CONTROL OR ANTI-LOCK KICKS IN. THIS HAS NOT BEEN A ONE TIME INCIDENT, BUT ALSO DOES NOT OCCUR EVERY TIME. *TR

MY 2010 PRIUS LOSES BRAKING FOR A SPLIT SECOND WHEN GOING OVER A POT HOLE. I'VE NOTICED THIS A COUPLE OF TIMES. *TR

BRAKING WHILE DRIVING OVER A POTHOLE CAUSES THE 2010 PRIUS TO MOMENTARILY FEEL LIKE IT'S ACCELERATING RATHER THAN BRAKING. THIS HAS RESULTED IN NEAR-ACCIDENTS A COUPLE OF TIMES. THIS HAPPENS MORE CONSISTENTLY WHEN TURNING WHILE BRAKING OVER UNEVEN PAVEMENT. I CAN REPEAT THIS RELIABLY IN SPECIFIC LOCATION, AND IT HAPPENS ELSEWHERE TOO.*TR

WE PURCHASED A 2010 TOYOTA PRIUS IN JULY 2009 AND HAVE BEEN HAVING PROBLEMS WITH THE BRAKES THAT CORRESPOND PRECISELY TO WHAT IS NOW BEING WIDELY REPORTED IN THE NEWS. SPECIFICALLY, WHEN GOING OVER BUMPS IN THE ROAD WHILE BRAKING, SEVERAL TIMES I HAVE EXPERIENCED THE CAR SUDDENLY AND MOMENTARILY SPEEDING UP AND LURCHING FORWARD RATHER THAN SLOWING DOWN. MY WIFE HAS ALSO REPORT BRAKING PROBLEMS. INDEED, JUST LAST WEEK I QUERIED HER TO MAKE SURE IT WAS THE BRAKES RATHER THAN THE ACCELERATOR, AND SHE CONFIRMED THE PROBLEM OCCURRED WHILE BRAKING. SO FAR THESE INCIDENTS HAVE NOT RESULTED IN DAMAGE OR CRASH, BUT WE ARE OBVIOUSLY NOW VERY CONCERNED ABOUT USE OF THE CAR, ESPECIALLY DURING SLIPPERY WINTER CONDITIONS HERE IN WASHINGTON, DC. THE DATE BELOW ONLY REPRESENTS THE MOST RECENT OF MULTIPLE TIMES WE EXPERIENCED THIS PROBLEM. *TR

I PURCHASED A 2010 PRIUS ON JANUARY 18, 2010. WITHIN 1 WEEK OF THE PURCHASE, THE CAR HAD HYDROPLANED TWO TIMES. EACH TIME, I THOUGHT I HAD HIT "BLACK ICE" AS THERE HAD BEEN RAINY/COLD CONDITIONS THAT EVENING.THE FEELING I HAD WAS THAT THE CAR SURGED FORWARD MOMENTARILY AS I WAS DRIVING SLOWLY OR SLOWING DOWN. THESE 2 INCIDENTS HAPPENED WITHIN A MILE OF EACH OTHER. I WAS DRIVING VERY SLOWLY AT THE TIME. I CALLED THE DEALER, NORTHBROOK TOYOTA, AND REPORTED THE PROBLEM TO THE SALESMAN. THE PROBLEM HAPPENED AGAIN A WEEK LATER WHEN THE SURGED FORWARD AS I PASSED OVER WHAT LOOKED LIKE A SLICK SEWER CAP. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES WERE ULTRA-SENSITIVE AND WHEN SHE LIGHTLY DEPRESSED THE PEDAL, THE VEHICLE WOULD JERK AS IF SHE MADE AN ABRUPT STOP. OTHER TIMES, SHE HAD TO PUSH THE BRAKE PEDAL EXTREMELY HARD TO STOP THE VEHICLE. SHE CALLED THE DEALERSHIP AND WAS TOLD THAT IT WAS NOT A PROBLEM. SHE HAD NOT CONTACTED THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS 1,218. THE FAILURE MILEAGE WAS APPROXIMATELY 1,200.

BRAKING DOES NOT OCCUR IMMEDIATELY ON OCCASION ON TOYOTA 2010 PRIUS. TRACTION LIGHT EVEN COMES ON AS IF YOU ARE SKIDDING. THIS HAS OCCURRED SEVERAL TIME FOR ME SINCE OWNING THE CAR IN SEPT 2009. I HAVE HAD A PRIUS FROM EACH GENERATION (THIS IS MY THIRD PRIUS) - THIS DID NOT OCCUR IN THOSE. DID CALL DEALER ON THIS. EXACT DATES NOT KEPT BUT WILL PUT AN ESTIMATE OF LAST TIME BELOW. *TR

UNDER CERTAIN CONDITIONS MY 2010 TOYOTA PRIUS MOMENTARILY LOOSES ITS BRAKES. I TOOK DELIVERY IN OCTOBER, 2009. *TR

WHEN DRIVING AND BRAKING, IF YOU HIT A BUMP OR POT HOLE, THE BRAKES RELEASE AND THE CAR DOESN'T SLOW DOWN. THIS HAS HAPPENED A NUMBER OF TIME SINCE I BOUGHT THE CAR IN AUGUST 2009. *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

PROBLEM VEHICLE: 2010 TOYOTA PRIUS PURCHASED IN SEPTEMBER 2009. WHEN FOOT IS ON OR OFF BRAKE AT SPEEDS < APPROX 45 MPH, AND A LARGE BUMP/POT HOLE/ETC IS TRAVERSED, THE BRAKES FAIL FOR ABOUT A SECOND (WHICH FEELS LIKE AN UNCONTROLLED ACCELERATION). FOR THAT SECOND THE CAR IS UNCONTROLLED. THIS HAS HAPPENED AT LEAST 15 TIMES SINCE SEPTEMBER 2009. THIS IS ESPECIALLY DANGEROUS IS SUDDEN BRAKING IS REQUIRED OR ROAD CONDITIONS ARE HAZARDOUS. *TR
