2007 Toyota Prius SERVICE BRAKES, HYDRAULIC

APPLIED BRAKE WHILE RUNNING LESS THAN 5 MPH IN FLAT PARKING LOT WITH FLAT SURFACE ROAD; I WAS FEELING LIKE FLOATING OR LIKE EARTH QUAKE WHILE INSIDE THE CAR. IT HAPPENED TWO TIMES WITHIN 3 MINUTES TIME FRAME. WHEN MY CAR WAS ABOUT 40K MILE (NOW MY CAR IS 75K MILES), AND ONLY HAPPENED TWO TIMES IN THE PAST HAS NOT OCCURRED AGAIN YET. *JB

BRAKE LOCKUP WHILE DRIVING LESS THAN 20 MPH ON NORMAL FLAT ROAD (RAIN). *JB

I OWN A 2007 TOYOTA PRIUS, AND THE PROBLEM NOW BEING INVESTIGATED ON THE 2010 MODELS WHERE THE BRAKES FAIL MOMENTARILY WHEN DRIVING OVER A POTHOLE OR BUMPY ROAD IS A VERY COMMON OCCURRENCE FOR ME, AND HAS BEEN SINCE WE BOUGHT THE VEHICLE IN SEPTEMBER OF 2008. *TR

IF YOU DRIVE OVER A MANHOLE OR POTHOLE WHILE APPLYING BRAKES, THE BRAKES WON'T WORK AND THE LITTLE ANTI-SKID LIGHT ON THE DASHBOARD GOES ON. YOU HAVE TO WAIT UNTIL AFTER YOU PASS OVER THE POTHOLE BEFORE YOU APPLY THE BRAKES. SOMETIMES NOT POSSIBLE TO DO THIS IF YOU NEED TO STOP IN A HURRY. CONTACTED MY TOYOTA DEALER ABOUT THIS IN JULY 2007 AND WAS TOLD THIS WAS NORMAL. "JUST DON'T USE THE BRAKES UNTIL AFTER YOU PASS THE POTHOLE." WAS WHAT I WAS TOLD. *TR

I AM DESCRIBING A REPEATING ISSUE WITH MY 2007 TOYOTA PRIUS. THIS FAILURE OCCURS WHEN I DRIVE OVER BUMPY SURFACES, A LARGE POTHOLE, OR AN AREA WITH A DIP IN THE ROAD. OFTEN, WHEN FACED WITH THESE CONDITIONS, THE CAR STUTTERS AND LURCHES AND THE VEHICLE STABILITY ASSIST LIGHT FLASHES. AT TIMES, THE CAR'S SLIP AND STUTTER SEEMS TO LAST SEVERAL SECONDS AFTER HITTING THE ROUGH PATCH IN THE ROAD. WHILE IT SEEMS TO EXACERBATE THE PROBLEM IF I AM TURNING OR BRAKING, I SHOULD POINT OUT THAT I SOMETIMES EXPERIENCE THIS LURCHING AND STALLING SOMETIMES WHEN I AM SIMPLY DRIVING ALONG AT 35 MPH AND HIT A POTHOLE. IT OFTEN SEEMS TO OCCUR IN A SITUATION WHERE BRAKING OR TURNING IS INVOLVED, BUT IT SEEMS MORE RELATED TO THE VSA PROCESS. I AM REPORTING THIS FAILURE BECAUSE I HAVE SEEN NEWS REPORTS OF AN INVESTIGATION OF THE 2010 PRIUS MODEL. THE DESCRIPTION OF THE BRAKE FAILURE REPORTED IN THE MEDIA ARE BASICALLY THE SAME AS MINE.*JB

I DRIVE A 2007 MODEL YEAR PRIUS, MANUFACTURED BY TOYOTA. OVER THE NEARLY 3 YEARS OF OWNERSHIP - I HAVE EXPERIENCED, AT LEAST 10 TIMES, A SEEMINGLY SMALL DEFECT DURING LIGHT BRAKING CONDITIONS. WHAT HAPPENS IS WHEN I TAP ON THE BRAKES DURING A SLOWDOWN TO A TRAFFIC LIGHT (WHERE I MAY BE SLOWLY PUMPING THE BREAKS TO SLOW), THE TRACTION CONTROL LIGHT WILL POP ON - AND THE CAR WILL SEEMINGLY LURCH FORWARD FOR A SECOND OR TWO, AS IF IT WANTS TO ACCELERATE. THE MATTER ALWAYS RESOLVES ITSELF - AND I DON'T FEEL IN DANGER OR ANYTHING LIKE THAT. HOWEVER, IT HAS HAPPENED MULTIPLE TIMES, AND IS ALWAYS ACCOMPANIED BY THE TRACTION CONTROL LIGHT - AND THE LURCHING FORWARD I TOLD YOU ABOUT. I DO NOT BELIEVE THIS IS THE TRACTION CONTROL SYSTEM WORKING - BECAUSE NONE OF THE SITUATIONS I'M SPEAKING INVOLVED CONDITIONS WHERE I WAS LOSING TRACTION. BEING THAT MOST OF THE PRIUS PROBLEMS SEEM TO BE IN THE 2010 MODEL, I'M NOT SURE IF YOU'VE HAD OTHER COMPLAINTS ABOUT THIS. I HAD NOT FELT THE NEED TO REPORT THIS UNTIL NOW - BECAUSE I FEEL THAT PERHAPS YOU MIGHT WANT TO EXAMINE THIS, ESPECIALLY IF YOU'RE GETTING FEEDBACK FROM OTHER DRIVERS OF THE SECOND GENERATION PRIUS. *JB

MY 2007 PRIUS HAS THE BRAKE PROBLEM IDENTIFIED ON THE 2010 MODELS -- WHEN I GO OVER A POT-HOLE OR BUMP THE BRAKES "SLIP." THIS PROBABLY HAPPENS ONCE A MONTH AND HAS HAPPENED SINCE I PURCHASED THE CAR IN THE FALL OF 2007. THE BRAKES GRAB AGAIN AS SOON AS I HIT SOLID ROAD. *JB

THE BRAKING ISSUES THAT I HAVE EXPERIENCED FOR THE 2007 PRIUS WITHIN MONTHS OF BUYING THE VEHICLE ARE THE SAME ISSUES THAT ARE CURRENTLY BEING REPORTED FOR THE 2010 PRIUS. I HAVE A PRIUS WITH TRACTION CONTROL. THERE ARE TWO THINGS WITH THE TRACTION CONTROL THAT HAPPEN ON A REGULAR BASIS LIVING IN ST. GEORGE, UTAH. ONE IS WHEN I COME OUT OF A PARKING LOT THAT HAS THE STEEP DIP FOR WATER CONTROL THE TRACTION CONTROL SYSTEM MISFIRES ON DRY, CLEAN SURFACES AND IN MANY CASES LEAVES ME DEAD ON THE ROAD FOR A FEW SECONDS IN WHICH THE CAR WILL NOT MOVE AT ALL. THIS ALSO HAPPENS WHEN I DRIVE ON ROADS WHERE THERE IS A DRAINAGE LID IN THE MIDDLE OF THE ROAD, AND I AM ACTUALLY NOT ATTEMPTING TO BRAKE. THE SECOND IS WHEN I BRAKE. IF THERE IS ANY ROUGH OR UNEVEN SURFACES, BUMPS, OR DIRT ROADS, I HAVE TO ANTICIPATE THAT THE BRAKING SYSTEM WILL FAIL AND/OR I WILL HAVE TO QUICKLY PUMP THE BRAKES AND LEAVE EXTRA BRAKING ROOM. I HAVE NOT TAKEN THE VEHICLE TO TOYOTA BECAUSE HAVING HAD A 1999 TACOMA WHOSE BRAKES WOULD FAIL ON A REGULAR BASIS TO THE POINT, FOR WHICH THEY CONTINUALLY REPLACED SENSORS, I SOLD IT AFTER I HAD IT LESS THEN ONE YEAR, I DON'T EXPECT TOYOTA TO DO ANYTHING ABOUT IT. I JUST DRIVE DIFFERENTLY. THE SPEEDING OUT OF CONTROL, FOR ME, ONLY OCCURS WHEN I HAVE CRUISE CONTROL ON. MANY TIMES WHEN I PRESS ON THE BRAKE THE CAR ACTUALLY SPEEDS UP WITH A JERK OR I WILL LOOK DOWN AT MY SPEED AND CRUISE CONTROL WILL HAVE INCREASED IT BY 10 OR 15 MPH. *JB *TR

ON 2 SEPARATE EVENTS, THE BRAKE SYSTEM IN OUR 2007 TOYOTA PRIUS FAILED. IT FELT AS IF THERE WAS NO BRAKE FLUID IN THE SYSTEM AND THE BRAKES BECAME DANGEROUSLY SPONGY AND UNRESPONSIVE. THE DEALER MADE TWO SEPARATE FIXES TO THE SYSTEM. *TR

TL*THE CONTACT OWNS A 2007 TOYOTA PRIUS. WHILE DRIVING 25 MPH THE VEHICLE ACCELERATED ON ITS OWN WHEN THE BRAKE PEDAL WAS ENGAGED. THE VEHICLE TOWED TO THE DEALER WHO STATED THAT THE BRAKES WERE DAMAGED. THE ENTIRE BRAKE SYSTEM WAS REPAIRED UNDER THE WARRANTY. THE FAILURE RECURRED 3 MONTHS AFTER THE VEHICLE WAS REPAIRED; HOWEVER, TOYOTA ADVISED THE CONTACT THAT THEY WOULD ASSUME RESPONSIBILITY. THE FAILURE MILEAGE WAS 10000 AND THE CURRENT MILEAGE WAS 46390.

2007 TOYOTA PRIUS. I NOTICED BRAKES SLIPPING OR DELAYED ENGAGEMENT VERY SOON AFTER PURCHASE. WHEN THE BRAKE HESITATES THE SLIPPERY ROAD ICON ALWAYS COMES ON. I TOOK THE CAR INTO THE DEALER 3 TIMES WITHIN THE FIRST 12-18 MOS. THEY KEPT IT OVERNIGHT AND HAD THE TECH DRIVE IT WITHOUT THE PROBLEM OCCURRING FOR HIM. SINCE THE WARRANTY EXPIRED I HAVE DECIDED TO LIVE WITH THE PROBLEM. I SINCE PURCHASED NEW TIRES WHICH HAS DECREASED THE FREQUENCY OF THE BRAKE HESITATION. NOW I FEAR SERIOUS BRAKE FAILURE. I CALLED THE DEALER DAVE WHITE OF TOLEDO, OHIO TODAY AND WAS TOLD BY THE SERVICE DEPT.TO WAIT FOR A LETTER RE. THE BRAKE AND ACCELERATOR PROBLEMS WHICH SHOULD ARRIVE IN ABOUT A MONTH. I AM CONCERNED ABOUT THE SAFETY OF MY CAR IN THE INTERIM. ACTIONS TO DATE HAVE DONE MUCH TO HEIGHTEN AWARENESS OF PROBLEMS BUT HAVE DONE NOTHING TO INCREASE SAFETY IN THE SHORT TERM. I HOPE THAT THE NHTSA WILL ADDRESS THIS ISSUE. *TR

I HAVE A 2007 TOYOTA PRIUS AND ITS BRAKES HAVE FAILED MOMENTARILY ON SEVERAL OCCASIONS. EVENTS THAT SEEM TO TRIGGER THE FAILURE INCLUDE HITTING POTHOLES, TURNING SHARPLY AT SPEED, AND DRIVING ON VERY ROUGH ROAD SURFACE. THE FAILURE IS MOMENTARY AND HAS NOT RESULTED IN ACCIDENT OR INJURY...JUST A SKIPPED HEART BEAT. *TR

TL*THE CONTACT OWNS A 2007 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 6 MPH IN THE SNOW THE BRAKES FAILED TO STOP THE VEHICLE. AS SHE DEPRESSED THE BRAKE PEDAL, THE VEHICLE CONTINUED TO SLIDE FORWARD. THE CHECK ENGINE ILLUMINATED INTERMITTENTLY PRIOR AND AFTER THE FAILURE OCCURRED. THE DEALER WAS UNABLE TO DUPLICATE OR DIAGNOSE THE FAILURE. THE FAILURE MILEAGE WAS 82,000. UPDATED 04/14/10

I WAS IN STOP AND GO TRAFFIC ON I275 IN TAMPA IN MY 2007 TOYOTA PRIUS DURING MORNING RUSH HOUR. THE MOST I WAS DOING DURING THIS TIME WAS 15MPH. I ALWAYS STAY MORE THAN ENOUGH BEHIND THE CAR IN FRONT OF ME. I APPLIED THE BRAKES AND IT WAS LIKE I WAS ON ICE SKATES. THE ROAD WAS DRY BUT IT WAS LIKE I HAD NO BRAKES AND NO CONTROL AND JUST SLID INTO THE CAR AHEAD OF ME. I TOLD THE OFFICER WHO WROTE ME UP A TICKET THAT MY BRAKES FAILED, I ALSO CONSTANTLY TOLD MY CAR INSURANCE AND THE CAR REPAIR COMPANY TO CHECK MY BRAKES BECAUSE THEY FAILED. *TR

I HAVE A 2007 TOYOTA PRIUS. I LIVE IN NEW ENGLAND. I HAVE NOTICED THAT THE BRAKES DO NOT STOP THE CAR IN SLUSHY CONDITIONS, EVEN IF THE ROAD SURFACE IS NOT ICY. THIS SITUATION REPEATS ITSELF WHENEVER THE WEATHER CONDITIONS ARE WET AND NEAR 32 DEG. FAHRENHEIT. THE CAR JUST SLIDES STRAIGHT FORWARD WITH NO FISH-TAILING WHEN THE BRAKES ARE APPLIED. OTHER CARS STOP JUST FINE IN SLUSH, BECAUSE THE ROAD SURFACE HAS ADEQUATE TRACTION. I KNOW SEVERAL OTHER PRIUS OWNERS, AND THEY ALL EXPERIENCE THIS PROBLEM. I HAVE STOPPED DRIVING THE PRIUS WHENEVER POSSIBLE IN THESE WEATHER CONDITIONS. I HAVE FILLED IN A RANDOM INCIDENT DATE BELOW, BECAUSE THE PROBLEM HAPPENS EVERY TIME THE WEATHER CONDITIONS ARE AS DESCRIBED. *TR

I OWN A 2007 PRIUS. WHEN I BRAKE AND HIT A BUMP IN THE ROAD, THE CAR DOES MOMENTARILY JERK FORWARD. THIS HAS HAPPENED SINCE I OWNED THE CAR, BUT DID NOT FILE A COMPLAINT UNTIL NOW. IT IS A RATHER HELPLESS FEEL WHEN THIS HAPPENS, IT'S ONLY MOMENTARY AND I REALLY ONLY NOTICE IT AT SLOWER SPEEDS (LIKE WHEN SLOWING FOR A STOP SIGN), AND COULD BE DANGEROUS ESPECIALLY IF YOUR NOT EXPECTING IT.*TR

I OWN A 2007 TOYOTA PRIUS, AND SINCE I HAVE HAD THE CAR I HAVE CONTINUOUS ISSUES WITH MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING OVER UNEVEN ROAD SURFACES, POTHOLES AND BUMPS, SO I DON'T THINK IT'S JUST AN ISSUE WITH THE 2010 MODELS. I ASKED MY DEALER, OLATHE TOYOTA IN OLATHE, KS, ABOUT IT LAST YEAR AND THEY TOLD ME IT WAS JUST PART OF THE AUTO-CORRECT SYSTEM THAT'S AN ADVANCE FEATURE INSTALLED IN THE CAR AND FOR ME NOT TO WORRY... THAT WAS HOW IT WAS SUPPOSE TO WORK THEY SAID. HOWEVER, YOU MOMENTARILY LOSE CONTROL OF THE BRAKING SYSTEM AND SOMETIMES THE STEERING EVEN AUTO CORRECTS ITSELF BUT NOT ALWAYS IN THE RIGHT WAY...I HAVE HAD SEVERAL INSTANCES OF IT HAPPENING AND CORRECTING IN A WAY WHERE IT ALMOST CAUSED ME TO WRECK. IT'S SO NERVE RACKING THAT I TRY AND AVOID BUMPS OR POTHOLES AS MUCH AS POSSIBLE. TO ADD TO MY CONFUSION THOUGH, I RECEIVED A FLOOR-MAT RECALL LETTER FROM TOYOTA BACK IN NOVEMBER 2009 BUT NEVER RECEIVED ONE ABOUT A RECALL ON THE PRIUS GAS-PEDAL. BUT AREN'T THE FLOOR-MATS WHAT TOYOTA ORIGINALLY SAID WAS WRONG WITH THE SYSTEMS BEFORE THEY ADMITTED TO THE GAS PEDAL IN THE OTHER MODELS, SO WHY DIDN'T I RECEIVE A GAS PEDAL RECALL LETTER AS A 2007 PRIUS OWNER, IF IT REALLY WASN'T THE FLOOR-MATS THAT THEY RECALLED? NEEDLESS TO SAY, I'M A CONFUSED 2007 PRIUS OWNER WITH HUGE CONCERNS OVER THE SAFETY OF MY CAR THAT I STILL OWE MONEY ON. SHOULD I TALK TO MY DEALER AGAIN ABOUT THE BRAKING/AUTO-CORRECT SYSTEM/GAS PEDAL ISSUES ? I'M JUST NOT CLEAR ON WHAT MY OPTIONS ARE BUT I AM CONCERNED ABOUT THE SAFETY OF MY CAR, NOT ONLY FOR ME BUT FOR OTHER DRIVERS ON THE ROAD, ESPECIALLY SINCE I HAVE A 45 MINUTE COMMUTE TO WORK EACH WAY FIVE TIMES A WEEK IN HEAVY HIGHWAY TRAFFIC. *TR

I HAVE A 2007 PRIUS. MY COMPLAINT REGARDS THE BRAKING SYSTEM. MY ISSUE HAPPENS UNDER LOW SPEED CONDITIONS WHILE BRAKING. WHILE BRAKING AND HITTING A MINOR BUMP OR POTHOLE, THE BRAKE WILL COMPLETELY DISENGAGE FOR A SPLIT SECOND AND REENGAGE. THE STABILITY CONTROL LIGHT WILL TURN ON WHEN THIS HAPPENS AS WELL. THIS WAS MENTIONED TO THE DEALER AND THEIR RESPONSE WAS "I'VE HEARD THAT BEFORE. IT'S BECAUSE IT HAS A LIGHT FRONT END." SEEMED LIKE AN UNINFORMED ANSWER TO ME. THIS ISSUE OCCURS FREQUENTLY AND HAS OCCURRED SINCE DAY ONE OF OWNERSHIP. *TR

I HAVE A 2007 TOYOTA PRIUS AND I HAVE EXPERIENCED A BRAKE PROBLEM. MY BRAKES WILL BECOME UNRESPONSIVE IF I HIT A SERIES (2 OR 3 IN A ROW) OF SHARP BUMPS MY BRAKES WILL NOT WORK TO THE POINT THAT I HAVE TO REAPPLY THE BRAKES. IF I HAD BEEN CLOSER TO THE CARS IN FRONT OF ME I WOULD HAVE CRASHED INTO THEM. NOW THAT I AM AWARE OF THIS PROBLEM I JUST ALLOW EXTRA SPACE IN CASE I HIT BUMPS. THE PROBLEM CAN BE DUPLICATED AT A PARTICULAR PLACE IN THE ROAD THAT I TRAVEL. *TR

I PURCHASED A 2007 PRIUS ON 8/31/07. BOTH MY WIFE AND I OCCASIONALLY EXPERIENCE A SLIGHT FORWARD SURGE OF THE VEHICLE WHEN THE BRAKES ARE APPLIED. I HAD THE CAR INSPECTED ON 5/14/08 FOR THIS CONCERN AND HAVE A TOYOTA WORKORDER STATING THE ISSUE AND INDICATING THAT THEY COULD NOT FIND A PROBLEM. I REPEATED MY CONCERNS ON ADDITIONAL SERVICE VISITS (NOT WRITTEN UP ON THE WORKORDER AND, AGAIN, NOTHING WAS FOUND. ON 8/3/09 I WAS INVOLVED IN A MINOR ACCIDENT WHEN I FAILED TO COMPLETELY STOP BEHIND A CAR SITTING AT A TRAFFIC LIGHT AND STRUCK THAT CAR IN THE REAREND. MY CAR REQUIRED A BUMPER REPLACEMENT AS THE PLASTIC BUMPER CRACKED ON IMPACT WHILE THE OTHER VEHICLE ONLY EXPERIENCED SCRATCHED PAINT ON IT'S REAR BUMPER. I AM CONCERNED THAT THERE IS SOMETHING SYSTEMIC WRONG WITH THE BRAKES ON MY CAR AND WANTED TO REPORT THIS AND, HOPEFULLY, HEAR BACK AS TO THE NUMBER OF SIMILAR REPORTS THAT YOU HAVE RECEIVED. *TR

LOSS OF CONTROL OF PRIUS BRIEFLY WHEN BRAKING ON ICY OR UNEVEN CONDITIONS. EVERY TIME I GO OVER A PARTICULAR BRIDGE HERE IN THE SUBURBS OF PHILADELPHIA THE PROBLEM OCCURS. MOST RECENTLY BRAKES SHUDDERED FOR ABOUT 10 SECONDS ON ICY CONDITIONS, NOT LIKE IN ABS WAY BUT IN A WAY IN WHICH I WASN'T SURE IF THEY WERE GOING TO ENGAGE OR NOT. *TR

PLEASE PROBE 2007 TOYOTA PRIUS BRAKES TOO. MY BRAKES HAVE FELT WEAK FOR SOME TIME NOW. I BROUGHT IT TO THE REPAIR SHOP IN DECEMBER 2009 AND THEY SAID THEY WERE FINE AND WERE AT 50% WORN. THE REPAIR SHOP THOUGHT I WAS NUTS. THEY STILL GRIND, SQUEAK AND FEEL WEAK. *TR

I WON A 2007 TOYOTA PRIUS. I HAD TWO ACCIDENTS IN LAST 4 MONTHS TIMEFRAME (BOTH INCIDENTS WERE FILED). IN BOTH THE CASES, I HAVE OBSERVED THAT THERE HAS BEEN BRAKING ISSUE. ESPECIALLY DURING SNOW/ICY CONDITIONS, THE CAR DID NOT STOP. WHEN BRAKING, IF THERE IS LITTLE ICE I WOULD EXPECT IT TO STOP AT NORMAL DISTANCE. BUT IT CROSSES THE ROAD UNTIL SOME DISTANCE, BEFORE IT COMES TO COMPLETE STOP. THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR SOME TIME. I AM GOOD FAN OF PRIUS AND IT'S MY 3RD PRIUS IN THE FAMILY SINCE 2005. HONESTLY, THE BRAKING DISTANCE & SLIDING BOTHERING ME RECENTLY ALOT. *TR

WHEN I APPLY THE BRAKES THEY SEEM TO START TO BRAKE AND THEN THE CAR ACTUALLY GOES FASTER FOR A COUPLE SECONDS AND THEN IT BRAKES AGAIN. IT HAS ALWAYS DONE THIS AND HAS BEEN DISCONCERTING TO ME. IT JUST FEELS LIKE THE BRAKES ARE FAILING BUT THEN THEY KICK BACK IN. I GUESS AS I UNDERSTAND IT, ITS WHEN THE ABS KICKS IN, BUT IT SEEMS LIKE AN UNNECESSARILY LONG TIME FROM ANY OTHER CAR I HAVE DRIVEN. *TR

TL*THE CONTACT OWNS A 2007 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY BETWEEN 20-30 MPH ON A ROUGH ROAD SURFACE. WHILE BRAKING THE ANTI-LOCK BRAKE SYSTEM WARNING INDICATOR ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE FAILED TO SLOW DOWN WITH A SLIGHT LOSS OF VEHICLE CONTROL FOR A FEW SECONDS. THE VEHICLE WAS ABLE TO RESUME NORMAL OPERATION. THE FAILURE OCCURRED WHENEVER ENCOUNTERING AN UNEVEN OR SNOW COVERED ROAD CONDITION. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THERE WAS NO RESOLUTION. THE FAILURE MILEAGE WAS UNKNOWN.
