2010 TOYOTA PRIUS BRAKES ON TWO SEPARATE TIMES HAVE ALMOST CAUSED AN ACCIDENT. BOTH TIMES SLIPPERY CONDITIONS WERE PRESENT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 50 TO 55 MPH ON NORMAL ROAD CONDITIONS PRESSURE WAS APPLIED TO THE BRAKE PEDAL, FOLLOWED BY NO POWER RESPONSE FOR A SECOND. THE FAILURE OCCURRED INTERMITTENTLY. IN ADDITION, WHEN AFTER A COMPLETE STOP THE VEHICLE BEGAN SHAKING EXCESSIVELY. THE AUTHORIZED DEALER AND MANUFACTURER HAVE BEEN NOTIFIED OF THE MALFUNCTIONS. THE FAILURE MILEAGE WAS 400.

WHEN SLOWING DOWN, IF THE CAR HITS A POTHOLE OR BUMP IN THE ROAD, IT SEEMS TO ACCELERATE. AS SOON AS I PUT PRESSURE ON THE BRAKE, IT STOPS. IT ALMOST FEELS LIKE THE CAR JUMPS AHEAD FOR A BRIEF MOMENT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 10 MPH OVER A SPEED BUMP OR A POTHOLE WITH HER FEET ON THE BRAKE PEDAL THE VEHICLE LUNGED FORWARD AND ACCELERATED. THE DEALER STATED THAT THE VEHICLE WAS PERFORMING NORMALLY SINCE THE ELECTRICAL ENGINE WAS SWITCHING TO THE GASOLINE ENGINE. THE FAILURE MILEAGE WAS 6,000.

TOYOTA PRIUS 2010 MODEL: BRAKE LAG. I GATHER NHTSA IS CONSIDERING A RECALL. THIS IS TO FURTHER YOUR DATA. I TOOK MY 2010 PRIUS IN TO 355 TOYOTA, ROCKVILLE, IN NOVEMBER TO COMPLAIN ABOUT THE BRAKES DISENGAGING WHEN BEING APPLIED OVER ROUGH TERRAIN, LEADING TO A 4 - 6 FOOT JUMP FORWARD THEN RE-ENGAGEMENT OF THE BRAKES. I LODGED THIS CONCERN AS PART OF GETTING AN OIL CHANGE SERVICE, AND I HAVE THIS COMPLAINT IN WRITING ON THE DOCKET. THEY TOLD ME THE PROBLEM WAS JUST NORMAL ANTILOCK BRAKING. THE PROBLEM HAS OCCURRED MULTIPLE TIMES SINCE, CAUSING ABOUT A 4 - 6 FOOT JUMP BEFORE THE BRAKE REENGAGES. WITH ALL THE ICE WE HAVE HAD RECENTLY, I CAN NOW ASSURE MYSELF THAT THIS ISSUE IS NOT ABOUT THE ANTILOCK BRAKES, WHICH HAVE A TOTALLY DIFFERENT FEEL, AS THEY SHOULD. THE BRAKE DISENGAGEMENT ALMOST CAUSED AN ACCIDENT ON MONDAY THIS WEEK ON E STREET AS THE CAR HIT AN ICE PATCH AND THE BRAKE DISENGAGED MOMENTARILY. I THINK THE PRIUS IS A GREAT CAR, BUT, THIS PROBLEM IS DANGEROUS AND NEEDS TO BE FIXED. WHEN I CALLED 355 TOYOTA YESTERDAY WHEN IT BECAME EVIDENT THAT I WASN'T THE ONLY PERSON REPORTING THIS, THEY WERE VERY NICE BUT I AM NOT SURE THAT TOYOTA HAS PROVIDED THEM WITH A SOLUTION. *TR

WHILE DRIVING MY 2010 TOYOTA PRIUS I APPROACHED A RED LIGHT WITH TRAFFIC STOPPED IN FRONT OF ME AT THE LIGHT. IT HAD BEEN RAINING AND THE PAVEMENT WAS WET. I BEGAN TO GENTLY BRAKE TO STOP WELL BEHIND THE STOPPED TRAFFIC AT THE LIGHT. I PASSED OVER SOME ROUGH/BUMPY ROAD AND THE BRAKES FAILED FOR ABOUT 1 SECOND AND THE CAR SHOT FORWARD APPROXIMATELY 10 FEET. THE BRAKES THEN BEGAN WORKING AGAIN IN ABS MODE AND I WAS ABLE TO AVOID HITTING THE STOPPED TRAFFIC IN FRONT OF ME BY ONLY 12 TO 24 INCHES. THIS HAS HAPPENED A NUMBER OF TIMES SINCE PURCHASING THIS 2010 PRIUS IN NOVEMBER OF 2009. IT HAS HAPPENED 3 OR 4 TIMES IN THE 3 MONTHS I HAVE OWNED THE VEHICLE. THE LOSS OF BRAKING CAUSES A SEVERE SENSE OF PANIC AND DISTRESS AND THE VEHICLE DOES SHOOT FORWARD FOR THAT SECOND OR SO. AND IN THE CASE NOTED ABOVE CAME VERY CLOSE TO CAUSING AN ACCIDENT. IT IS ONLY TIME BEFORE IT WILL CAUSE AN ACCIDENT AND HARM TO ME AND/OR OTHERS. TOYOTA HAS NOT OFFERED ANY REMEDY. THEY KNOW THE PROBLEM EXISTS AND HAVE KNOWN IT FOR QUITE SOME TIME. COMMUNICATION FROM TOYOTA ABOUT THE PROBLEM HAS BEEN ALMOST NON-EXISTENT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIAMTELY 20 MPH AND MAKING A LEFT OR RIGHT TURN WITH THE BRAKE PEDAL ENGAGED, FOR A FRACTION OF A SECOND.

I HAVE A 2010 PRIUS PURCHASED IN LATE JULY 2009. I HAVE DEFINITELY HAD PROBLEMS WITH THE BRAKING SYSTEM IN WINTER WEATHER ON SLIPPERY SURFACES. WHEN BRAKING, IT FEELS LIKE THE ANTILOCK BRAKE SYSTEM FAILS AND THE WHEELS LOCK UP MOMENTARILY. I DON'T LET MY WIFE OR KIDS DRIVE THE CAR IN SLIPPERY CONDITIONS. THIS IS DEFINITELY AN ISSUE FOR ME AND I BELIEVE IT SHOULD BE INVESTIGATED AND PURSUED. I HAVE CONTACTED THE DEALER - ALDERMAN'S TOYOTA OF RUTLAND, VT ABOUT THE ISSUE. THEY ARE AWARE OF THE PROBLEM. *TR

2010 TOYOTA PRIUS PURCHASED IN OCTOBER 2009. WHEN BRAKING, CAR HITS A BUMP IN THE ROAD OR ON A ROUGH ROAD, BRAKES APPEAR TO FAIL FOR APPROXIMATELY 2-3 SECONDS. *TR

MOMENTARY LOSS OF BRAKING WHEN ABS ACTIVATES CAUSES CAR TO TRAVEL AN UNEXPECTED 12 FEET. HAS HAPPENED 4 TIMES SINCE DEC 2009. HAPPENS WHEN SLOWING DOWN FOR STOP SIGN, OR MAKING LEFT OR RIGHT TURN IN TRAFFIC, WHEN THERE IS A SLIPPERY PATCH CAUSING ABS TO TRIGGER. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHENEVER HE ENGAGED THE BRAKE PEDAL WHILE DRIVING VARIOUS SPEEDS RANGING FROM 5 MPH OR HIGHER OVER A POTHOLE, A BUMP IN THE ROAD, ICE OR ANY CHANGE IN THE ROAD SURFACE THE VEHICLE MOMENTARILY ACCELERATED BEFORE THE BRAKES WOULD ENGAGE. HE ALSO STATED THAT HE HEARD A RATTLING NOISE WITHIN THE ENGINE COMPARTMENT AFTER THE VEHICLE WAS STARTED. THE DEALER WAS CONTACTED AND A DIAGNOSTIC TEST WAS PERFORMED BUT PRODUCED NO CODES. THE FAILURE COULD NOT BE DUPLICATED AND THE VEHICLE WAS RELEASED TO THE OWNER. NO REPAIRS WERE MADE TO THE VEHICLE. THERE WERE NO RECALLS. THE FAILURE MILEAGE WAS 2,000 AND THE CURRENT WAS 8,000.

DRIVING MY 2010 PRIUS TODAY, I EXPERIENCED A BRAKE FAILURE SUCH AS THE ONE I'VE BEEN HEARING ABOUT ON THE NEWS. HERE'S WHAT HAPPENED: I WAS BRAKING, SLOWING TO A STOP APPROACHING A STOPLIGHT (GOING NO FASTER THAN 10 MPH AT THE TIME), MY CAR ROLLED OVER A MANHOLE COVER THAT WAS SLIGHTLY LOWER THAN THE SURFACE OF THE ROAD (NO MORE THAN ONE INCH DEEP) AND SUDDENLY IT FELT LIKE MY CAR WAS GLIDING ON ICE WITH NO ABILITY TO STOP, THE BRAKES HAD COMPLETELY FAILED; ADDITIONALLY, I HEARD A SLIGHT GRINDING SOUND COME FROM THE FRONT RIGHT WHEEL WELL. I TOOK MY FOOT OFF THE BRAKE, RE-DEPRESSED THE PEDAL, AND EVERYTHING WAS INSTANTLY BACK TO NORMAL. THE DURATION OF THE INCIDENT WAS NO MORE THAN A SECOND, BUT IT WAS TERRIBLY ALARMING JUST THE SAME. FOLLOWING THIS INCIDENT, I HAVE CONTACTED TWO DIFFERENT TOYOTA DEALERSHIPS' SERVICE DEPARTMENTS WHO STATED THAT THEY DID NOT CURRENTLY HAVE ANY REPAIR PLANS FOR THIS PROBLEM, APOLOGIZED FOR THE "INCONVENIENCE," AND ONE OF THE DEALERSHIPS (TOYOTA OF HOLLYWOOD (CA)) TOOK MY PHONE NUMBER WHILE THE OTHER DEALERSHIP TOLD ME TO WAIT FOR A LETTER FROM TOYOTA. I INQUIRED OF TOYOTA OF GLENDALE (CA) IF I SHOULD GET A RENTAL CAR FOR THE TIME BEING (HOPING TO BE OFFERED A LOANER) AND THEY TOLD ME NOT TO, AND TO 'DRIVE SAFE.' I'M TOTALLY LIVID, THIS IS A VERY SCARY PROBLEM TO EXPERIENCE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY BETWEEN 10 TO 20 MPH ON AN UNEVEN ROAD SURFACE; PROCEEDING TO A COMPLETE STOP AND APPLYING PRESSURE TO THE BRAKE PEDAL, WAS FOLLOWED BY A NO POWER RESPONSE.

THE VEHICLE HAS NOT BEEN INSPECTED FOR THE MALFUNCTION. THE FAILURE MILEAGE WAS 300. UPDATED 02/26/10 *BF THE CONSUMER STATED SHE WAS SATISFIED THAT THE COMPLAINT DESCRIBED THE PROBLEM SHE REPORTED. UPDATED 04/29/10.*JB

BRAKES TEMPORARILY DISENGAGE DURING BRAKING IF CAN HITS A BUMP OR POTHOLE IN THE ROAD. IT IS ONLY A MOMENTARY INSTANCES BEFORE THE BRAKES RE-ENGAGE, BUT IT GIVES THE FEELING OF ACCELERATING. IT HAS HAPPEND TO ME ABOUT A HALF DOZEN TIMES SINCE PURCHASING THE CAR (2010 TOYOTA PRIUS) IN AUGUST 2009. LUCKILY NO CARS OR PEDESTRIANS WERE IN FRONT OF ME WHEN THIS PROBLEM OCCURRED. *TR

I HAVE NOTICED THE BRAKES IN OUR 2010 PRIUS ARE NOT AS EFFECTIVE AS SLOWING THE CAR AS THEY WERE IN OUR 2004 PRIUS. ON JANUARY 3 I WAS EXITING THE HIGHWAY. AS I WAS ABOUT TO LEAVE THE HIGHWAY WHILE BRAKING I ENCOUNTERED A SLIGHT BUMP IN THE PAVEMENT. I NOTICED THAT WHEN THIS OCCURRED THE BRAKING EFFECTIVENESS DROPPED SUBSTANTIALLY, TO THE POINT WHERE THE CAR FELT AS THOUGH THERE WERE NO BRAKES BEING APPLIED. AS SOON AS THE BUMP WAS GONE THE BRAKING EFFECTIVENESS RETURNED. *TR

2/13, THE DAY AFTER MY CAR WAS "FIXED" UNDER THE RECALL, MY BRAKES FAILED. I WAS ON THE WAY TO THE AIRPORT, AND THE BRAKES FAILED . WHEN I RETURNED HOME FROM MY TRIP, I BROUGHT IT IN TO TOYOTA KEARNY MESA IN SAN DIEGO, WHO FOUND NOTHING WRONG. MY BRAKES FAILED AGAIN A WEEK AGO. I WAS DRIVING ON A SMOOTH ROAD, SLOWING DOWN FOR A LIGHT, WHEN SUDDENLY THE CAR SPEEDED UP AND I WENT STRAIGHT THOUGH THE RED LIGHT. NO CARS WERE NEARBY, SO I DID NOT CRASH AND NO ONE WAS HURT. AGAIN, TOYOTA FOUND NOTHING WRONG. THEY TELL ME THAT THEY CAN'T FIX IT UNLESS THEY CAN "REPLICATE" THE PROBLEM. THEY WANT ME TO RETURN THE LOANER CAR TOMORROW MORNING AND DRIVE HOME WITH MY PRIUS AND I'M SCARED. *TR

TOYOTA 2010 PRIUS BRAKE RECALL PATCH WAS ONLY PARTLY EFFECTIVE. IN THE WINTER THE CAR COULD LOOSE BRAKING FOR 6 TO 8 FEET AFTER HITTING A ROUGH SPOT, POT HOLE ETC. NOW IT SKIPS MAYBE 2 TO 3 FEET. THE DEALER AND TOYOTA FACTORY PEOPLE TELL ME IT'S NORMAL ANTI-LOCK BRAKE ACTION. I SAY I HAVE DRIVEN MANY CARS WITH ANTI-LOCK BRAKES AND THEY TO NOT LOOSE BRAKE ACTION, THEY PULSE THE BRAKES. THE TOYOTA FACTORY PEOPLE TELL ME THE CAR IS STILL BRAKING EVEN IF IT FEELS LIKE IT ISN'T. I DO NOT AGREE WITH THAT FOR A SECOND. THE DEALER WANTS TO TEST DRIVE THE CAR TO DETERMINE CONDITION. HOWEVER IT ONLY HAPPENS MAYBE ONCE A WEEK AND NOT AT EVERY BUMP OR JOLT OF THE SUSPENSION. I FEEL TOYOTA DOES NOT HAVE A PROPER FIX AND IS NOT WORKING ON ONE. THEY ARE TRYING TO TALK US PRIUS OWNERS INTO ACCEPTING THIS FLAW AS NORMAL FOR THE CAR. *TR
