2010 Toyota Prius complaints

OVER THE PAST 2-3 WEEKS WE HAVE HAD UNPREDICTABLE OCCURRENCES OF THE BRAKES OF OUR 2010 PRIUS GRABBING/LOCKING WHEN ONLY GENTLE/GRADUAL PRESSURE HAS BEEN APPLIED TO THE BRAKE PEDAL. THE SUDDEN FULL-BRAKING OF THE VEHICLE CAUSES IT TO LURCH AND, IF DRIVERS DO NOT TAKE OFF THE BRAKE COMPLETELY, TO STOP SHORT. *TR

WHEN BRAKING AT SLOW SPEEDS AND ON BUMPY ROADS, THE CAR WILL SURGE FORWARD A BIT RATHER THAN STOP AS EXPECTED. *TR

2010 PRIUS BRAKING ISSUE. I HAVE FELT THE LOSS OF BRAKING WHILE GOING OVER POTHOLES ATLEAST 4 TIMES SINCE I HAVE OWNED MY 2010 PRIUS SINCE LAST YEAR. *TR

2010 PRIUS. I HAVE THE BRAKING PROBLEM EXACTLY AS IT'S DESCRIBED IN YOUR REPORT, "MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING OVER AN UNEVEN ROAD SURFACE, POTHOLE OR BUMP". THIS SEEMS TO OCCUR ABOUT EVERY 50 MILES OF CITY DRIVING, BUT IT'S TOTALLY UNPREDICTABLE. WHEN IT HAPPENS, I HAVE TO DEPRESS THE BRAKE PEDAL ABOUT TWO MORE INCHES TO REGAIN THE LOST BRAKING. I INDICATED THIS ON TOYOTA'S NEW OWNER SURVEY BUT NEVER HEARD FROM THE COMPANY. PLEASE ADD THIS TO THE LIST OF COMPLAINTS. *TR

I BOUGHT A 2010 PRIUS V ON 10-31-09. ON SEVERAL OCCASIONS, I HAVE EXPERIENCED THE TEMPORARY LOSS OF BRAKING NOW MAKING NEWS. I'VE NOTICED IT AT LEAST A HALF DOZEN TIMES ON SNOWY OR ICY ROADS. MISTAKENLY ATTRIBUTING THE ZERO SLOWING TO BEING ON BLACK ICE, I PUMPED THE BRAKES. THE BRAKES IMMEDIATELY TOOK EFFECT AND SLOWED THE CAR. THE IMMEDIATE RESPONSE UPON PUMPING THE BRAKES, PLUS THE NUMBER OF TIMES THIS HAS HAPPENED IN JUST THE HANDFUL OF TIMES I'VE DRIVEN ON SLICK ROADS, TELLS ME IT WASN'T BLACK ICE AT ALL. PLEASE DO SOMETHING ABOUT THIS. THANKS. *TR

2010 TOYOTA PRIUS. BRAKES WOULD NOT WORK AT LOW SPEED WHEN APPROACHING AN INTERSECTION COVERED WITH SAND/ GRAVEL FROM RECENT SNOW ABATEMENT WORK. CAR ROLLED THROUGH STOP SIGN. *TR

LOSS OF BRAKING CAPABILITY ON ROUGH SURFACE OR BUMPS. *TR

WHEN DRIVING MY CAR THE BRAKES DON'T ALWAYS SEEM TO RESPOND IMMEDIATELY. OCCASIONALLY, BUT NO ALWAYS, THE CAR WILL FAIL TO BRAKE WHEN PEDAL IS DEPRESSED AND SEEMS TO MOVE FORWARD FASTER BEFORE FINALLY BRAKING. IT IS SPORADIC AND WHEN I FIRST ASKED A DEALERSHIP THEY SAID I WAS JUST UNACCUSTOMED TO PRIUS BRAKING SYSTEMS AND THAT OVER TIME I WOULD BECOME MORE FAMILIARIZED. THIS HAS HAPPENED SEVERAL TIMES AND EACH TIME THE VEHICLE WAS AT A LOW VELOCITY = 35MPH. *TR

WHILE BRAKING ON A DOWNHILL ROAD AND APPROACHING A SIGNAL LIGHT, I HIT A POTHOLE AND THE MOMENTARILY LOST BRAKING POWER AND THE VEHICLE LURCHED FORWARD. I CONTINUED TO APPLY THE BRAKES AND THEY ENGAGED AGAIN. FORTUNATELY, I WAS DECELERATING AND THERE WERE NO OTHER VEHICLES IN FRONT OF ME. I CONCERNED THAT THIS COULD OCCUR AGAIN WITH OTHER CONSEQUENCES. *TR

I HAVE A 2010 PRIUS AND WOULD LIKE TO LOG A COMPLAINT THAT I TOO AM EXPERIENCING THE LAG EFFECT ON THE BRAKING SYSTEM. I READ TODAY THAT IT COULD BE A COMPUTER SOFTWARE PROBLEM. PLEASE LOG THIS COMPLAINT SO THE REAL MAGNITUDE OF THIS PROBLEM IS TALLIED. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 35 MPH ON AN UNEVEN ROAD SURFACE APPROACHING A TRAFFIC SIGNAL WHEN THE VEHICLE LUNGED FORWARD IMMEDIATELY AFTER THE BRAKE PEDAL WAS ENGAGED. THE DRIVER HAD TO APPLY EXCESSIVE FORCE TO THE BRAKE PEDAL TO STOP THE VEHICLE. THE FAILURE OCCURRED WHENEVER ENCOUNTERING AN UNEVEN ROAD SURFACE AND POTHOLES. THE FAILURES OCCURRED ON THREE SEPARATE OCCASIONS. THE VEHICLE WILL BE TAKEN TO AN AUTHORIZED DEALER FOR INSPECTION. THE FAILURE MILEAGE WAS 1,800.

BRAKE WAS NOT WORKING WHEN APPLIED TRYING TO SLOW DOWN ON A SNOW COVERED FROZEN ROAD AT ABOUT 25MPH. IT'S NOT FOR A STOP OR SUDDEN BRAKING. *TR

AT LEAST 4 TIMES WHILE BRAKING AS I TURN ONTO ANOTHER ROAD IN MY 2010 PRIUS, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. IT IS VERY JARRING AND FRIGHTENING AND THERE IS CLEARLY SOMETHING WRONG. *TR

I HAVE A 2010 PRIUS AND AM HAVING BRAKING PROBLEMS WHEN DRIVING OVER POT HOLES, BUMPY SERVICES, OR DOWN HILLS. THE 2010 PRIUS RELEASES THE BRAKES WHEN DRIVING OVER THESE SURFACES AND HAS BECOMES DANGEROUS TO ME AND MY FAMILY. I ALSO LIVE ON A RATHER STEEP HILL AND WHEN TRAVELING DOWN THE HILL ANY DEBRIS ON THE SURFACE OF THE ROAD SUCH AS LEAVES CAUSES THE BRAKES TO GIVE WAY. "PLEASE HELP" "PLEASE HELP". *TR

SUDDEN INCREASE IN SPEED DURING BRAKING OVER UNEVEN SURFACE, POTHOLES, SNOW, RAIL ROAD TRACKS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN HE HIT A BUMP IN THE ROAD OR A POTHOLE AND DEPRESSED THE BRAKE PEDAL, THE BRAKES SEEMED TO RELEASED OR LET GO; INSTEAD OF SLOWING DOWN, THE VEHICLE WOULD CONTINUE MOVING AT THE SAME SPEED. HE NOTICED THE ISSUE ON AN INTERMITTENT BASIS AND ONLY WHEN ON A ROUGH OR BUMPY SURFACE. HE HAD NOT TAKEN THE VEHICLE TO THE DEALERSHIP BUT CALLED; HE WAS TOLD THAT THEY WERE LOOKING INTO THE PROBLEM. HE HAD NOT CALLED THE MANUFACTURER TO-DATE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS APPROXIMATELY 7,200. THE FAILURE MILEAGE WAS APPROXIMATELY 2,100.

TL* THE CONTACT HAS A 2010 PRIUS. THE VEHICLE IS HAVING A BRAKE FAILURE WHEN GOING OVER BUMP OR UNEVEN PAVEMENT. THE CONTACT STATED THAT THIS HAPPENS REGARDLESS OF WEATHER CONDITIONS. THE VEHICLE ALMOST HIT ANOTHER VEHICLE WHEN GOING AROUND A CURVE AND HIT A BUMP. THE VEHICLE THEN SEEM TO START TO SLIDE. THE FAILURE MILEAGE WAS 5000. THE VEHICLE CURRENT MILEAGE WAS 15858.

DURING THE FIRST SNOWFALL IN DEC 09 I WAS DRIVING MY WIFE'S 2010 PRIUS BECAUSE I WANTED TO TAKE THIS NEW CAR OUT TO SEE HOW IT WOULD PERFORM IN ICY CONDITIONS. AS I APPROACHED A ROUNDABOUT/TRAFFIC CIRCLE AT LESS THAN 10 MPH THE BRAKES DID NOT RESPOND AT FIRST. I NEARLY REAR ENDED THE SUV THAT WAS STOPPED AT THE CIRCLE. THE GROUND WAS COVERED IN ICE. I HAD TO SPIN THE CAR AT AN ANGLE TO AVOID HITTING THE SUV. I AM NOW READING THAT OTHER PEOPLE HAVE HAD THE SAME PROBLEM. I READ THAT TOYOTA HAS ADDRESSED THAT THERE IS A PROBLEM BUT HAS NOT ISSUED A RECALL. I HAVE EXPERIENCED BRAKE SLIPPAGE/NOT ENGAGING WHEN FIRST PRESSING ON THE BRAKES 6-10 TIMES WITH THIS CAR. APPLYING THE BRAKES OVER POTHOLES SEEM TO HAVE THE SAME EFFECT BUT IT SEEMS MORE DANGEROUS THAT THIS HAPPENS ON ICY ROADS SINCE I LIVE IN THE FROZEN TUNDRA OF GREEN BAY WISCONSIN. *TR

TL* THE CONTACT HAS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT IF HE TRIES TO STOP AND HIT A BUMP OR POTHOLE THE BRAKES SEEM TO RELEASE. WHEN GOING DOWN A HILL ON A BUMPY ROAD THE VEHICLE WAS UNABLE TO STOP UNTIL THE VEHICLE REACH A SMOOTH PATCH OF ROAD. THE FAILURE MILEAGE WAS 800 AND CURRENT MILEAGE WAS 4000.

THIS IS IN REFERENCE TO MY 2010 TOYOTA PRIUS WHICH HAS ON SEVERAL OCCASIONS EXHIBITED THE MOMENTARY LOSS OF BRAKING WHEN THE PEDAL IS DEPRESSED AND I HIT A BUMP. THIS HAS OCCURRED THREE SEPARATE TIMES SINCE JULY OF 2009 WHEN I PURCHASED A NEW PRIUS FROM SUNRISE TOYOTA IN OAKDALE NY. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE APPROACHING A DRIVEWAY AT SPEEDS UNDER 10 MPH AND MAKING A LEFT TURN, THE BRAKES FAILED MOMENTARILY. WITHIN SECONDS THE BRAKES BECAME TO FUNCTION NORMALLY. THE DEALER WAS NOTIFIED AND THE CONTACT IS AWAITING REPAIRS. THE FAILURE AND CURRENT MILEAGES WERE UNDER 200.

MY 2010 TOYOTA PRIUS WAS PURCHASED IN JULY 2009. WHEN I TRY TO BRAKE ON A BUMPY ROAD THE BRAKES FAIL AND THE CAR ACTUALLY MOMENTARILY ACCELERATES. *TR

2010 TOYOTA PRIUS PURCHASED JULY 2009 I'VE HAD THE BRAKING PROBLEM THAT'S BEEN DESCRIBED IN THE NEWS RECENTLY ON A NUMBER OF OCCASIONS. WHEN I FIRST REPORTED IT TO TOYOTA DURING MY FIRST OIL CHANGE AT THE DEALERSHIP, THEY TOLD ME "THAT IT WAS NORMAL". -- NOT! *TR

MY 2010 PRIUS IS EXPERIENCING THE BRAKE PROBLEM AS EXPLAINED BY OTHERS, I.E., HIT A BUMP IN THE ROAD WHILE APPLYING BRAKES AND AN UNEXPECTED BUT MOMENTARY INCREASE IN SPEED. THIS HAPPENED 3 TIMES SO FAR AND I HAVE OWNED THE PRIUS FOR 6 MONTHS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 20 MPH HE APPLIED THE BRAKE PEDAL; HOWEVER, THE VEHICLE DID NOT SLOW DOWN INSTEAD IT ACCELERATED AT VARIOUS SPEEDS. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE DURING A TEST DRIVE. HE STATED THAT THE FAILURE OCCURRED SIX TIMES INTERMITTENTLY CONTACT IS CONCERNED THAT IF HE CONTINUED TO DRIVE THE VEHICLE THE FAILURE COULD CAUSE A CRASH TO OCCUR. THE FAILURE MILEAGE WAS 9,000 AND THE CURRENT MILEAGE WAS 10,500.

I HAVE EXPERIENCED MULTIPLE INCIDENTS OF LOSS OF BRAKING CONTROL IN MY 2010 PRIUS. TODAY I WENT TO PUT ON MY BRAKES AND THE SYSTEM LOCKED UP ON ME AND THEN, LUCKILY, RELEASED AND I REGAINED CONTROL OF MY BRAKES BEFORE HITTING THE CAR IN FRONT OF ME. *TR

I OWN A 2010 PRIUS. WHEN I APPLY THE BRAKE TO STOP THE CAR, SOMETIMES THE BRAKE STOPS WORKING. IF I THEN QUICKLY TAKE MY FOOT OFF THE BRAKE AND REAPPLY, IT WORKS AGAIN AND THE CAR STOPS. THIS HAS OCCURRED ON SEVERAL OCCASIONS SINCE DECEMBER 2009. *TR

I HAVE EXPERIENCED THE IDENTICAL PROBLEM THAT IS BEING DESCRIBED WITH THE BRAKES ON MY 2010 PRIUS. WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. I THOUGHT THIS WAS A "NORMAL" ODDITY THAT WAS OCCURRING AS A RESULT OF THE ABS, BUT NOW REALIZE THAT THIS IS A SYSTEMIC PROBLEM. *TR

I HAVE A 2010 PRIUS. IF BRAKING WHILE GOING OVER A POTHOLE OR BUMP, THE BRAKES SEEM TO RELEASE, CAUSING THE VEHICLE TO ACCELERATE MOMENTARILY. CONSISTENTLY HAPPENS IN THESE CIRCUMSTANCES. *TR

I HAVE NOTICED AN ISSUE WITH THE BRAKES NOT WORKING FOR A SECOND WHEN I AM GOING DOWNHILL IN THE PARKING GARAGE, AND GOING OVER A SPEED BUMP, WHEN I GO OVER THE BUMP WHILE THE BRAKES ARE SLIGHTLY PRESSED, IT MOMENTARILY LOSES BRAKING AFTER GOING OVER THE BUMP. I THINK IT IS AN ISSUE WITH SWITCHING FROM REGENERATIVE BRAKING, TO REGULAR MECHANICAL BRAKING. I AM ABLE TO REPEAT THE ISSUE CONSISTENTLY IN ONE LOCATION IN A PARKING STRUCTURE THAT I PARK IN. I NOTICED IT AROUND OCT 2009 AND HAVE BEEN NOTICING IT SINCE THEN. *TR

I PURCHASED A 2010 TOYOTA PRIUS (MODEL V) IN AUGUST 2009 AND HAVE HAD ISSUES WITH THE BRAKES EVER SINCE THEN. WHEN DRIVING ON ROUGH OR UNEVEN PAVEMENT, IF I DEPRESS THE BRAKE TO SLOW DOWN, THE CAR SEEMS TO SKID OR ALMOST SHOOT FORWARD INSTEAD OF BRAKING. THE END RESULT IS THAT INSTEAD OF IMMEDIATELY STOPPING, THE CAR ENDS UP SLIDING FOR ABOUT A SECOND BEFORE STOPPING, WHICH COULD OBVIOUSLY LEAD TO AN ACCIDENT GIVEN THE EXTRA DISTANCE THE CAR IS TRAVELING INSTEAD OF BRAKING IMMEDIATELY. AFTER THIS HAPPENED REPEATEDLY ON A STREET NEAR MY HOME IN SAN FRANCISCO, I TOOK THE CAR TO THE TOYOTA DEALER FROM WHICH I BOUGHT IT ON NOVEMBER 24, 2009 (CITY TOYOTA IN DALY CITY). AFTER EVALUATING THE CAR OVERNIGHT, THEY GAVE ME A WRITTEN REPORT (A COPY OF WHICH I'M HAPPY TO PROVIDE) AND TOLD ME THAT IT HAD SOMETHING TO DO WITH THE ANTILOCK BRAKES BUT SAID IT WAS A "NORMAL CHARACTERISTIC OF [THE] VEHICLE." NOTE THAT WHILE THEY WERE LOOKING AT MY PRIUS, THEY GAVE ME ANOTHER LOANER 2010 PRIUS (MODEL III) AND THAT CAR HAD THE EXACT SAME ISSUE (ALSO NOTED ON THEIR WRITTEN REPORT). AFTER LISTENING TO THE NEWS AND SEEING AN ARTICLE THIS MORNING WHERE TOYOTA ADMITTED THERE WERE BRAKING ISSUES WITH 2010 PRIUS CARS MADE BEFORE JANUARY 2010, I BECAME EXTREMELY CONCERNED ABOUT THE SAFETY OF MY CAR AND POTENTIAL FOR AN ACCIDENT. I ALSO UNDERSTAND THAT THERE ARE OVER 100 COMPLAINTS FOR THE SAME ISSUE AND WANT TO ADD MY EXPERIENCE TO THAT LIST TO ENSURE THAT TOYOTA DOES A PROPER RECALL OF MY 2010 PRIUS TO

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WITH HIS FEET ON THE BRAKE PEDAL WHILE DRIVING 20 MPH OVER A BUMP IN THE ROAD OR A POTHOLE THE VEHICLE LUNGED FORWARD AND ACCELERATED. THE DEALER HAS NOT DIAGNOSED THE FAILURE AND IT OCCURS MORE FREQUENTLY. THE FAILURE MILEAGE WAS 200.

I OWN A 2010 PRIUS SINCE AUGUST 2009. IN THE PAST MONTH OR SO, I NOTICED THAT WHEN I MADE A SLOW RIGHT TURN OR STOP ON A DRAINAGE GRILL, I SUDDENLY LOST BRAKE POWER. THE CAR LUNGES FORWARD FOR A FOOT OR TWO BEFORE IT STOPS UPON HARD STEPPING ON THE BRAKE PEDAL. I HAD A NEAR ACCIDENT ON FEB 2, 2010 AS I STOPPED AT A RED LIGHT UNDER A BRIDGE. THIS ANOMALY HAPPENS PRIMARILY AROUND CORNERS AND BUMPY ROADS. THE PROBLEM DID NOT HAPPEN AT THE BEGINNING SO I SUSPECT THAT WITH TIME, THE PROBLEM WILL GET PROGRESSIVELY WORSE. *TR

2010 TOYOTA PRIUS. CAR SEEMS TO SURGE FORWARD WHEN BRAKING ON ROUGH PAVEMENT SUCH AS POTHOLES. ALSO HAPPENED ONCE ON A WET DAY WHEN A FRONT WHEEL SLIPPED ON THE PAINTED STOP LINE BEFORE AN INTERSECTION. WE TOOK DELIVERY OF THE CAR IN JUNE 2009 AND THE FIRST INCIDENT WAS IN JULY 2009. *TR

2010 PRIUS BRAKE PROBLEM--I TOO HAVE HAD A FEW OCCURRENCES OF THE BRAKES ON MY 2010 PRIUS BRIEFLY FAILING. IT HAPPENS IF I BRAKE WHILE GOING OVER A POTHOLE WHILE BRAKING. MOST, BUT NOT ALL OF THE TIME THIS HAPPENS ON A WET ROAD. THE BRAKE PEDAL FEELS "MUSHY" AND THEN IN LESS THAN A SECOND THE REGULAR BRAKES TAKE OVER. I HAVE NEVER HAD THE ABS SYSTEM KICK IN--AT LEAST I HAVE NEVER FELT THE CHARACTERISTIC "SHUDDER" OF THE BRAKE PEDAL. SO FAR, NOT EVEN A CLOSE CALL, BUT IT IS VERY DISCONCERTING. DATE BELOW IS APPROXIMATE FIRST DATE. THERE HAVE BEEN 8-10 EPISODES. THE CAR HAS ABOUT 9500 MILES ON IT. *TR

I HAVE A 2010 TOYOTA PRIUS PURCHASE IN 9/2009. WHEN I SLOW DOWN TO STOP AND GO OVER A BUMP IT FEELS AS THOUGHT THE POWER BREAKS GO OUT AND THE VEHICLE SURGES FORWARD. THIS HAS OCCURRED SINCE WE PURCHASED THE VEHICLE. THE ORIGINAL EXPLANATION WAS THAT WE JUST NEED TO GET USED TO THE TRANSITION FROM GASOLINE POWER TO ELECTRIC POWER. HOWEVER, I DON'T FEEL THAT IS SUFFICIENT AS IT IS A VERY DANGEROUS SURGE. *TR

WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. *TR

WHEN SLOWING TO A RED LIGHT ON MD 212 AT US RT 1 IN BELTSVILLE, MD, MY 2010 TOYOTA PRIUS ROLLED OVER A BUMPY STRETCH OF ROAD AND THE REGENERATIVE BRAKES STOPPED BRAKING. THE CAR ROLLED FORWARD IN "FREE WHEEL" FASHION UNTIL I STOMPED ON THE BRAKES HARD AT WHICH POINT THE FRICTION BRAKES KICKED IN AND STOPPED THE VEHICLE IN TIME TO AVOID AN ACCIDENT WITH THE VEHICLE IN FRONT OF ME. THE TRACTION CONTROL INDICATOR LAMP LIT, AND REMAINED LIT UNTIL I RELEASED THE BRAKES TO ACCELERATE WHEN THE LIGHT TURNED GREEN. SEEMS TO BE THE SAME PROBLEM EVERYONE IS REPORTING IN THE NEWS THIS MORNING. I'VE HAD THE CAR 1.5 WEEKS, AND THIS IS THE FIRST TIME I'VE NOTICED THE PROBLEM, ALTHOUGH MY WIFE CLAIMS IT HAPPENED TO HER DURING OUR TEST DRIVE. *TR

2010 PRIUS BRAKE PROBLEMS. *TR

I UNDERSTAND TOYOTA KNEW ABOUT THE ANTI-LOCK BRAKE ISSUE ON PRIUS BUILD BEFORE JANUARY 2010. I OWN A 2010 PRIUS, PURCHASED IN OCTOBER 2009. I HAVE HAD ONE INSTANCE OF MOMENTARY BRAKE LOSS WHILE DRIVING OVER A BUMP. IT WAS A BIT FRIGHTENING AT THE TIME, BUT THE PROBLEM HAS NOT RE-OCCURRED. SO I HAVE NOT REPORTED THE INCIDENT UNTIL TODAY. I ASSUME MANY OTHER PRIUS OWNERS MAY HAVE EXPERIENCED THE SAME PROBLEM, BUT DID NOT COMPLAIN, SINCE THE OCCURRENCE IS SO INFREQUENT. IF TOYOTA CARES ABOUT SAFETY, THEY WILL DO THE RIGHT THING AND SAY "SAFETY IS TOYOTA'S NUMBER ONE PRIORITY. OUR ENGINEERS ARE WORKING ON A FIX FOR THE PRIUS'S WITH THE ANTI-LOCK BRAKE ISSUE AND REST ASSURED, TOYOTA WILL FIX THOSE VEHICLES." I AM VERY DISAPPOINTED THAT TOYOTA KNEW ABOUT THIS PROBLEM AND HAS NOT TAKEN CARE OF IT. HASN'T TOYOTA LEARNED ENOUGH FROM THE STICKY GAS PEDAL PROBLEM. TOYOTA NEEDS TO BE PROACTIVE IN MAINTAINING ITS IMAGE AS A RELIABLE CAR COMPANY THAT CARES ABOUT SAFETY. *TR

MY CURRENT 2010 PRIUS HAS THE "JUMP" ISSUE WITH THE BRAKES, BUT THIS IS NOT THE FIRST TIME THAT THIS HAS HAPPENED WITH THE PRIUS. MY 2002 PRIUS HAD THE SAME ISSUE, AND I WAS NOT THE ONLY ONE. I WAS A MEMBER OF A PRIUS YAHOO GROUP, AND THIS WAS A TOPIC OF DISCUSSION FOR A WHILE. SO WHILE I DO FEEL THE "JUMP" I JUST THOUGHT IT WAS PART OF THE PRIUS EXPERIENCE. WHENEVER I DRIVE OVER A POTHOLE, IT FEELS LIKE THE CAR IS TRYING TO JUMP IT. WHEN HITTING THE BRAKES, IT FEELS LIKE THERE IS ACCELERATION FOR JUST A SECOND. THIS IS NOT AN INTERMITTENT PROBLEM. IT HAPPENS EVERY TIME. *TR

WE TOOK THIS STATEMENT FROM THE NHTSA PRESS RELEASE WITH TODAY'S DATE, WHICH IS A 100% ACCURATE DESCRIPTION OF OUR PROBLEM: "MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING OVER AN UNEVEN ROAD SURFACE, POTHOLE OR BUMP" THIS IS NOT A ONE-TIME EVENT AS WE'VE NOTICED IT HAPPENING NUMEROUS TIMES SINCE PURCHASING THE PRIUS IN AUGUST 2009. THE HESITATION WE'VE EXPERIENCED USUALLY OCCURS WHEN DRIVING DOWN A STEEP HILL OR PASSING OVER A POTHOLE. *TR

I PURCHASED A PRIUS 2010 IN NOVEMBER 2009 AND HAVE TWICE EXPERIENCED A PROBLEM WHERE THE SKID WARNING LIGHTS UP ON THE DASHBOARD EVEN THOUGH THE CAR IS NOT SKIDDING AND AT THE SAME TIME I'VE FELT THE CAR ACCELERATE EVEN THOUGH MY FOOT IS ON THE BRAKE. THE FIRST TIME I THOUGHT I WOULD LOSE CONTROL OF THE CAR BUT KEPT MY FOOT ON THE BRAKE AND THE CAR EVENTUALLY STOPPED. THE SECOND TIME IT HAPPENED WHEN I WAS DOING A U-TURN IN AN UNLEVELED PART OF THE ROAD AND SINCE IT HAD HAPPENED BEFORE I JUST APPLIED THE BRAKE UNTIL THE SKID WARNING LIGHT TURNED OFF. I AM NOW SCARED ABOUT THE SAFETY OF THE BRAKING SYSTEM IN THIS CAR. *TR

2010 PRIUS IV PROBLEM WITH BRAKES WHEN GOING OVER BUMPS OR DIPS. BRAKES DO NOT WORK WHILE GOING OVER BUMP OR DIP. *TR

IN TWO SEPARATE INCIDENTS, I HAVE EXPERIENCED A SITUATION SIMILAR TO THOSE PROBLEMS REPORTED WITH THE 2010 PRIUS BRAKES. WHEN TRAVELING OVER A BUMP IN THE ROAD AND ON ANOTHER OCCASION OVER TRAIN TRACKS, I FELT THE ENGINE REV OR ACCELERATE. MY BRAKES WERE ALREADY ENGAGED, SO I JUST PRESSED ON THEM HARDER. *TR

I HAVE HAD TWO INSTANCES WHEN I LOST AT LEAST HALF OF MY BRAKING POWER WHEN GOING OVER A SLIGHT BUMP IN THE ROAD. THE FIRST INSTANCE WAS ABOUT TWO MONTHS AGO AND THE SECOND WAS ON FEB. 2ND. IN BOTH CASES I WAS COMING UP TO A FREEWAY ON RAMP STOP LIGHT AND WENT OVER A BUMP IN THE ROAD. I WENT BEYOND THE LIGHT BOTH TIMES AND FORTUNATELY THERE WERE NO OTHER CARS IN MY WAY. I ALSO HAVE A PROBLEM WITH THE BRAKES GRABBING SO SEVERELY THAT MY SEAT BELT ENGAGES WHEN I HAVE JUST FEATHER TOUCHED THE BRAKES. THIS HAS OCCURRED AFTER STARTING THE CAR AND RELEASING THE BRAKE TO MOVE FORWARD OR BACKWARD, BUT NOT YET STEPPED ON THE GAS. I HAVE HAD THE CAR INTO THE DEALERSHIP FIVE TIMES SINCE PURCHASING IT IN SEPTEMBER FOR THESE ISSUES AND HAVE REPEATEDLY BEEN TOLD THIS WAS NORMAL. I EVEN REQUESTED THAT A REGIONAL MECHANIC CHECK IT OUT AND HE DID SO. HE TOLD ME HE WAS ABLE TO HAVE THE CAR RESPOND AS I DESCRIBED AND IT WAS IN NORMAL RANGE. I DISAGREE. THERE HAS BEEN THREE OTHER PEOPLE WHO HAVE BEEN WITH ME WHEN THIS HAS OCCURRED AND NOT ONE OF THEM HAS CONSIDERED THIS ANYWHERE "NORMAL". I ONLY YESTERDAY LEARNED OF THIS AVENUE OF COMPLAINT OR I WOULD HAVE NOTIFIED YOU OF THIS PROBLEM EARLIER. THANK YOU FOR YOUR CONSIDERATION AND EFFORTS TO HOLD TOYOTA ACCOUNTABLE FOR THIS ISSUE. SO FAR I HAVE HAD ABSOLUTELY NO SUCCESS. *TR

2010 PRIUS WHICH LURCHED FORWARD EACH TIME I HIT A CERTAIN POTHOLE WHILE BRAKING. I AVOIDED THE PROBLEM BY AVOIDING THE POTHOLE. THE POTHOLE WAS LOCATED NEAR A STOP SIGN, SO I WAS ALWAYS BRAKING WHEN I HIT IT. *TR

I HAVE A NEW GEN III 2010 PRIUS II AND HAVE NOTICED THAT WHEN BRAKING THE CAR SEEMS TO SURGE FORWARD BEFORE DECELERATING WHEN I HIT A SERIES OF BUMPS OR A POTHOLE. IT IS UN-NERVING IN THAT EVEN AT SLOW SPEEDS LIKE WHEN COMING TO A STOP AT A STOP LIGHT, THE CAR WANTS TO CONTINUE FORWARD WITH AN UNCONTROLLED BURST. I HAVE CHANGED MY DRIVING SLIGHTLY TO GIVE MY SELF MOVE STOPPING ROOM, BUT SOMETIMES THERE IS A SERIES OF BUMPS IN THE ROAD AND IT JUST HAPPENS. I HAVE 10,000 MILES ON THE VEHICLE AND THIS HAS HAPPENED ABOUT 8 TO TEN TIMES TO ME, USUALLY WHEN I'M NOT EXPECTING ANYTHING TO HAPPEN BUT A SLOW BRAKING STOP. AS AN INCIDENT DATE IS REQUESTED, I AM PUTTING IN JUST ONE OF THE DATES THAT THIS OCCURRED, I HAVE NOT KEPT A RECORD OF THE DAYS, TRAVEL CONDITIONS, OR TIMES THAT THE INCIDENTS OCCURRED. THIS HAPPENS EVERYTIME MY WIFE DRIVES OVER A PARTICULAR SET OF TRAIN TRACKS NEAR WHERE WE LIVE. ALSO THIS OF COURSE HAS HAPPENED OVER TIME AND THE MILEAGE GIVEN IS ACTUALLY FROM THE DAY WE GOT IT TILL NOW, THIS IS AN ON GOING EVENT. *TR

BRAKE FAILURE ON MY 2010 PRIUS; THREE TIMES ON SNOWY/ICY ROADS IN JAN. 2010. CAUSING ME TO RUN TWO STOP SIGNS AND NARROWLY AVOIDING A COLLISION WITH A STOPPED VEHICLE. *TR

OUR 2010 TOYOTA PRIUS HAS EXPERIENCED THE LOSS OF BRAKE ACTION, OR THE SENSATION OF SPEEDING UP, WHEN GOING OVER A BUMP, OCCASIONALLY AROUND CORNERS AND ON UNEVEN SURFACES. *TR
