2007 TOYOTA PRIUS Service Brakes, Hydraulic Problems

The contact owns a 2007 Toyota Prius. The contact stated that while driving the speed was unknown due to the instrument cluster being inoperable. On another occasion while driving approximately 45 MPH, the brake pedal was depressed but failed to operate properly; however, on that occasion the instrument cluster was operating as designed. The vehicle stability control, ABS, and brake light warning lights were illuminated. The vehicle was taken to an independent mechanic and diagnosed with an actuator and brake booster failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 203,202.

Mileage: 203,202

I HAVE A 2007 PRIUS. THE CAR WAS INVOLVED IN AN ACCIDENT ON AUGUST 30, 2013 BECAUSE "NO BRAKE". IT WAS IN A STOP AND GO SITUATION TRAVELING AT ABOUT 20 MILES PER HOUR. THE CAR IN FRONT STOPPED, I SLAMMED ON THE BRAKE AND TOTAL BRAKE FAILURE. MY 16 YEARS OLD SON SITTING IN THE CAR OBSERVED THE "NO BRAKE" SCENARIO. THERE WAS A 25 POUND OF RICE IN THE TRUCK DID NOT EVEN MOVE. NO SKIP MARK... NOTHING. TOOK MY CAR TO LONGO TOYOTA AND FOUND NOTHING WITH THE BRAKE SYSTEM, OTHER THAN THE FRONT PAD WAS THIN, TIRES WERE MARGINAL ETC. NONE OF THE FINDINGS EXPLAINED THE NO BRAKE SCENARIO. FOR SOME REASON I CANNOT MAKE THIS NO BRAKE TO APPEAR AGAIN. I WANT PEOPLE TO AWARE OF THIS AND GATHER INFORMATION. IT APPEARS TO ME THE PRIUS CANNOT RESPONSE TO A QUICK STOP AT SLOW SPEED. SOMEHOW, THE CAR TAKES MORE THAN A SECOND FOR THE BRAKING TO KICK IN - THE REACTION DOES NOT APPEAR TO BE INSTANTANEOUS. AND IF YOU ARE TOO CLOSE, THAT EXTRA ONE SECOND WAIT WILL CAUSE A COLLISION.

I WAS DRIVING IN THE RIGHT LANE OF A 4-LANE BOULEVARD. THE VEHICLE AHEAD IN THE LANE TO MY LEFT SLOWED FOR A CAR IN FRONT WAITING TO MAKE A LEFT TURN, THEN SUDDENLY VEERED INTO MY LANE. I HIT THE BRAKES AS HARD AS I COULD, BUT FOR THE FIRST 2-3 SECONDS, MY CAR DIDN'T SLOW DOWN. IT ALSO DIDN'T MAKE ANY SOUNDS I WOULD HAVE EXPECTED FROM URGENT BRAKING - NO SCREECHING TIRES, ETC. I CONTINUED TO PUSH THE BRAKE PEDAL HARD. AFTER 2-3 SECONDS, THE BRAKES FINALLY GRABBED AND MY CAR PULLED TO THE RIGHT. I CONSIDERED MYSELF LUCKY THAT I HAD ENOUGH ROOM TO AVOID HITTING THE VEHICLE IN FRONT OF ME.

I FEEL MY 2007 TOYOTA PRIUS HAS A PROBLEM WITH ITS BRAKING SYSTEM AND HAVE TAKEN IT BACK TO THE DEALER. THEY HAVE ASSURED ME THAT THE ABS IS WORKING THE WAY IT SHOULD. THIS IS WHAT HAPPENS: WHEN I AM DRIVING ON A ROAD THAT IS BUMPY OR HAS POTHOLES AND I HAVE TO BRAKE, THERE SEEMS TO BE A DISCONNECT OR TOO MUCH OF A LAPSE IN TIME WHEN THE BRAKES FINALLY TAKE. IT IS ESPECIALLY DISCONCERTING WHEN GOING DOWN HILL. I HAVE HAD TIMES WHEN GOING DOWN HILL IF I WASN'T FAR ENOUGH BACK FROM THE CAR IN FRONT OF ME, I WOULD NOT BE ABLE TO STOP IN TIME.....NOT A GOOD FEELING. I AM NOW VERY COGNIZANT OF THIS FACT AND HAVE TO DRIVE TO ACCOMMODATE MY BRAKES. I SHOULD ALSO INFORM YOU THAT THE LITTLE YELLOW SLIDING CAR ON MY DASHBOARD LIGHTS UP WHEN ALL OF THIS IS HAPPENING. I'VE HAD THIS CAR FOR ALMOST THREE YEARS NOW AND I MUST SAY THAT IT HAS ALWAYS ACTED THIS WAY WHEN BRAKING. I SHOULD HAVE RETURNED IT TO THE DEALER AS SOON AS I NOTICED IT BUT BECAUSE IT WAS THE FIRST PRIUS I HAD EVER OWNED, I THOUGHT THIS WAS NORMAL FOR THIS VEHICLE. I AM NOW FEELING LESS AND LESS CONFIDANT ABOUT THIS CAR. WOULD YOU ASK THE TOYOTA COMPANY TO RECALL THE 2007 PRIUS'S AS THEY HAVE THE 2010 PRIUS'S FOR THE SAME PROBLEM? I DO NOT FEEL THIS IS ASKING TOO MUCH OF TOYOTA TO FIX THIS PROBLEM. THANK YOU *TR

WHILE DRIVING MY 2007 PRIUS IN A CONGESTED AREA, THE BRAKES DID NOT RESPOND WHEN DEPRESSED QUICKLY CONTRIBUTING OR CAUSING A LOW-SPEED COLLISION WITH THE VEHICLE IN FRONT OF ME. I FOUND THIS ARTICLE ON CNET REVIEWS THAT ACCURATELY MATCHES MY ISSUE. "TOYOTA REDESIGNED THE BRAKING SYSTEMS FOR THE 2010 PRIUS. THAT APPEARS TO BE TOYOTA'S RESPONSE TO THE FACT THAT THE U.S. GENERATION 2 PRIUS (2004-2009) HAS HAD LOW-SPEED BRAKE FAILURES REPORTED TO THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) AT 31 TIMES THE RATE OF SUCH FAILURES REPORTED FOR THE 2004-2009 COROLLA, WHICH OF COURSE HAS TRADITIONAL BRAKES. MANY OF THE PRIUS LOW SPEED BRAKE FAILURES WERE IN LOW-SPEED CITY TRAFFIC, RESULTING IN REAR-END COLLISIONS WITHOUT INJURY. IT APPEARS THAT THE SEVERAL COMPUTERS THAT CONTROL THE COMPLEX BRAKING SYSTEMS WERE TOO BUSY CALCULATING THE MOST EFFICIENT WAY TO APPLY THE BRAKES, AND DID NOT GET AROUND TO ACTUALLY APPLYING THEM, UNTIL IT WAS TOO LATE." *TR

TL*THE CONTACT OWNS A 2007 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT 48 MPH, THE BRAKES SUDDENLY LOCKED UP AND SWAYED TO THE LEFT SIDE WHEN HE DEPRESSED THE BRAKE PEDAL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP FOR DIAGNOSIS. THE DEALER REPAIRED THE AXLE AND DRIVER SIDE BODY BUT IT WAS UNKNOWN IF THE DEALER REPAIRED THE BRAKE SYSTEM. THE CONTACT BELIEVED THAT THE RAIN WAS A FACTOR IN THE FAILURE AS IT CAUSED THE COMPUTER CHIP FOR THE BRAKE PEDAL TO MALFUNCTION.

ON MONDAY, APRIL 12, 2010, IN THE MORNING, ON A RAINY DAY IN SACRAMENTO, CALIFORNIA, I WAS DRIVING ABOUT 15 MPH WHEN THE TRAFFIC IN FRONT OF ME SLOWED. I WAS DRIVING OVER RAILROAD TRACKS WITH STEEL PLATES BETWEEN THE TRACKS IN MY 2007 TOYOTA PRIUS. I BRAKED BUT THE CAR DID NOT STOP. I HAD TIME TO ACTUALLY LOOK DOWN AT MY FEET TO CONFIRM THAT IT WAS DEFINITELY THE BRAKES THAT I WAS APPLYING MAJOR PRESSURE TO. I ALSO NOTICED THAT THE LIGHT WAS ON INDICATING THAT THE CAR DID NOT HAVE TRACTION. I HIT THE CAR IN FRONT OF ME. THE FIRST WORDS OUT OF MY MOUTH WERE, "I HAD NO BRAKES, I'M SO SORRY, BUT I HAD NO BRAKES." THE INITIAL ESTIMATE FOR MY CAR IS OVER $6,000, I HAVE NOT HEARD WHAT THE ESTIMATE IS FOR THE OTHER CAR. I DID EVERYTHING I COULD HAVE DONE, THE CAR FAILED ME. *TR

1. WIFE IS LEARY OF DRIVING OUR 2007 TOYOTA PRIUS BECAUSE OF PROBLEM BRAKES. WE NEED A BETTER DESCRIPTION OF WHAT HAPPENS WHEN WE TRY TO TURN OFF THE ENGINE GOING 100 MPH. 2. LIGHTS ARE POOR. WE CANNOT SEE VERY FAR AHEAD IN THIS DEER INFESTED ENVIRONMENT. I HAVE BETTER LIGHTS ON MY 1997 HYUNDAI 3. ONE OR THE OTHER HEADLIGHT FLICKERS AND GOES OUT FOR NO UNDERSTANDABLE REASON. WE TURN THE LIGHTS OFF AND TURN THEM ON AGAIN AND IT WORKS OK. THIS COULD BE A SAFETY HAZARD. WHAT IS BEING DONE TO FIX IT. 4. SEATING. MY FIRST ENCOUNTER WITH THE TOYOTA COMPLAINT SYSTEM CAM ABOUT AS I WAS TRYING TO GET THE DRIVER SEAT MOVED BACK BECAUSE I HAVE LONG LEGS. THE DEALER SAID THEY HAVE NO WAY OF FIXING THIS BUT THAT I SHOULD GO TO THE AFTER MARKET. I ASKED IF TOYOTA WOULD ACCEPT AN AFTERMARKET SOLUTION. THE DEALER SAID THAT THEY WILL EVALUATE IT AFTER IT IS INSTALLED TO TELL US IF IT MEETS SAFETY SPECIFICATIONS NO AFTERMARKET SUPPLIER WILL TRY TO FIX THIS BECAUSE THEY HAVE NOT ASSURANCE THAT IT WILL BE ACCEPTED BY TOYOTA. YET TOYOTA GIVES NO TECHNICAL INFORMATION ABOUT WHAT IS ACCEPTABLE. I COMPLAINED FORMALLY TO THE DEALER AND GOT NOWHERE. I THEN SENT A FORMAL COMPLAINT TO NATIONAL TOYOTA. THEY PASSED THE COMPLAINT BACK TO THE DEALER FOR RESPONSE. FOR ME THIS IS A MAJOR FLAW IN THE TOYOTA COMPLAINT HANDLING SYSTEM. THEY HAVE A CLOSED LOOP WHEN IT COMES TO COMPLAINTS. 5. I LIKE THE CAR AND IT GETS THE MILEAGE I EXPECTED. I AM NOT SURE I WILL EVER GET ANOTHER TOYOTA IF THERE ARE REASONABLE ALTERNATIVE THAT GET GOOD MILEAGE. *TR

2007 TOYOTA PRIUS WITH TIRE FAILURE AND BRAKES GRABBING. *KB THE BATTERY AND HEADLIGHTS FAILED. THE CONSUMER STATED TOYOTA HAS SINCE REMOVED THIS PARTICULAR TYPE OF BULB AND ASSEMBLY FROM PRODUCTION. WHEN THE VEHICLE WAS 1 YEAR OLD THE CONSUMER WAS STOPPED BY THE POLICE AND GIVEN A WARNING FOR THE HEADLIGHT BEING OUT. HOWEVER, WHEN THE CONSUMER AND HER HUSBAND EXITED THE VEHICLE, THEY ALONG WITH THE POLICE OFFICER FOUND BOTH HEADLIGHTS WERE WORKING AND HE LET THEM GO WITHOUT A CITATION. THE CONSUMER HAS SINCE DISCOVERED THAT ONE HEADLIGHT OR THE OTHER WILL JUST GO OUT ON OCCASION DURING EVERY DRIVE. THE BRIGHTNESS OF THE HEADLIGHTS BEGAN TO DIM WHEN THE VEHICLE WAS ONLY A YEAR OLD. TOYOTA RECOMMENDED USING THE HEADLIGHTS LESS AND THEY FURTHER RECOMMENDED NOT USING THE HIGHLY TOUTED FEATURE THAT ALLOWS THE LIGHTS TO AUTOMATICALLY TURN OFF AFTER THE VEHICLE HAS BEEN TURNED OFF. LAST MONTH, THE CONSUMER RECEIVED A LETTER FROM TOYOTA REGARDING INFORMATION ABOUT A PROBLEM WITH THE HID HEADLIGHTS. THE LETTER STATED THE CUSTOMER SUPPORT PROGRAM WOULD REIMBURSE FOR SOME COST RELATIVE TO THE DEFECTIVE HEADLIGHTS. HOWEVER THE LOCAL DEALER DID NOT AGREE AND THE COST FAR EXCEEDED ANYTHING MENTIONED IN THE LETTER. THE DEALER INFORMED THE CONSUMER THE COST OF INSTALLATION FOR NEW BULBS WOULD BE $245 IN LABOR FOR EACH HEADLIGHT REPLACEMENT, THAT WAS IN ADDITION TO THE EXORBITANT COST OF THE BULBS THEMSELVES. *JB

I OWN A 2007 PRIUS. I HAVE NOTICED ON MANY OCCASIONS THAT WHEN YOU GO OVER A POTHOLE, OR THERE IS GRAVEL ON THE ROAD, THE TRACTION CONTROL LIGHT COMES ON AND FOR A MOMENT, THE CAR LOSES ITS BRAKING ABILITY. YOU ACCELERATE FOR A BIT BEFORE THE BRAKES COME ON AGAIN. IT IS VERY SCARY. THANK GOD NOTHING HAS HAPPENED, BUT HOW MANY INJURIES HAVE TO HAPPEN BEFORE TOYOTA DOES SOMETHING?! *TR

2007 TOYOTA PRIUS - BRAKING ISSUE ON RAINY OR SLICK SURFACE. UPON NORMAL BRAKING ON A SLICK OR WET SURFACE THE CAR BECOMES UNSTABLE, THE ABS BRAKING BECOMES IRREGULAR AND THE CAR GOES INTO A SKID AND DOES NOT STOP IN A NORMAL FASHION OR WITHIN A NORMAL BRAKING DISTANCE. THE SAME BRAKING RESPONSE OCCURS IF I HIT A POTHOLE WHILE BRAKING. THE TOYOTA DEALER TELLS ME THAT THIS IS NORMAL. IT IS NOT NORMAL AS I CANNOT DRIVE THE CAR UNDER WET OR SNOWY CONDITIONS FOR FEAR OF AN ACCIDENT. THE BRAKING ISSUES NOTED IN THE 2010 PRIUS MAKE ME WONDER IF A SIMILAR CONDITION EXISTS FOR THE 2007 MODEL YEAR. I SUSPECT THAT IT IS THE ECU WHICH IS FAULTY. *TR

I AM AWARE THAT THERE IS A PROBLEM WITH THE BRAKES ON THE TOYOTA PRIUS. NEWS REPORTS INDICATE THAT THE PROBLEM IS CONFINED TO THE 2010 MODEL, BUT I WOULD LIKE TO REPORT A BRAKE FAILURE INCIDENT WITH OUR 2007 MODEL PRIUS. IN JUNE OF 2009 MY WIFE AND I WERE DRIVING OUR PRIUS DOWN A HILL APPROACHING A STOP LIGHT. IT HAD BEEN RAINING AND THE PAVEMENT WAS WET, BUT THERE WAS NO STANDING WATER ON THE ROAD SURFACE. THE LIGHT TURNED YELLOW AS WE APPROACHED THE INTERSECTION AT A SPEED OF ABOUT 35 MPH. I APPLIED THE BRAKES BUT THE CAR CONTINUED TO MOVE FORWARD DOWN THE HILL WITH NO BRAKING ACTION AND NO DECELERATION. I HAD NO ALTERNATIVE BUT TO SPEED UP TO TRY GET THROUGH THE INTERSECTION BEFORE THE LIGHT TURNED RED. THE LIGHT DID TURN RED JUST BEFORE WE ENTERED THE INTERSECTION, BUT WE WERE ABLE TO MAKE IT THROUGH BEFORE ANY OPPOSING TRAFFIC ENTERED THE INTERSECTION. IT IS IMPORTANT TO NOTE THAT DURING THIS INCIDENT THE CAR SHOWED NO EVIDENCE OF BEING IN A SKID - - IT SIMPLY MOVED FORWARD WITHOUT ANY SWERVING. FURTHERMORE, THERE WAS NO VIBRATION IN THE BRAKE PEDAL NOR ANY SOUNDS THAT MIGHT BE ASSOCIATED WITH ANTI-LOCK BRAKE ACTION. I TOOK THE CAR TO THE TOYOTA DEALER AND ASKED THE SERVICE MANAGER IF THERE COULD BE SOMETHING WRONG WITH THE ANTI-LOCK SYSTEM. I WAS TOLD THAT THEY HAD NO WAY TO CHECK THAT. WE HAVE HAD NO FURTHER PROBLEM WITH THE BRAKES, BUT I AM CONCERNED THAT THIS BEHAVIOR MAY RECUR BECAUSE OF THE CURRENT BRAKING ISSUE. *TR

ALTHOUGH I HAVE NOT HAD AN ACCIDENT AS A RESULT IT IS A VERY UNCOMFORTABLE FEELING, BECAUSE YOU JUST DON'T KNOW IF THEY ARE GOING TO BRING YOU TO A STOP. I HAVE REPORTED THIS PROBLEM TO THE TOYOTA DEALER (SMART TOYOTA - MADISON, WI) AND THEIR ANALYSIS AT THE TIME I TOOK IT IN ON MAY 14, 2009 WAS THAT IT COULD NOT BE DUPLICATED AND ESSENTIALLY FOUND NOTHING WRONG. *TR

I READ ABOUT THE RECALL OF THE 2010 PRIUS CONCERNING THE ABS SOFTWARE. MY 2007 PRIUS EXPERIENCED THE SAME PROBLEMS RECENTLY WHEN I RAN OVER A CURB AT LOW SPEED AND THE CAR LURCHED FORWARD AT HIGH SPEED AFTER I APPLIED THE BRAKES AND I HIT A WALL ABOUT 5 FEET AWAY. DAMAGE TO MY CAR WAS A CRACKED BUMPER, SLIGHTLY DENTED HOOD, CRACKED HEAD LIGHT. I USED TO GET 50 TO 60 MILES PER GALLON AND I CAN NOT GET OVER 41 MILES PER GALLON NOW. I BOUGHT NEW TIRES AND HAD THEM BALANCED AND ALIGNED BUT THE MILEAGE HAD NOT IMPROVED. DAMAGES TO THE EXTERIOR OF THE CAR WILL AMOUNT TO ABOUT 2 TO 3 THOUSAND DOLLARS. MY TOYOTA DEALER SAYS THAT MY 2007 MODEL IS NOT PART OF THE RECALL. I HAVE READ BLOGS WHERE PEOPLE WITH MY MODEL TOYOTA HAVE HAD SIMILAR EXPERIENCES. I BELIEVE THAT THE ABS SOFTWARE IS FAULTY IN MORE THAN THE 2010 PRIUSES. *TR

PRIUS BRAKING BEHAVIOR I OWNED A NEW 2007 PRIUS WHICH I LEASED AND DROVE FOR THE FIRST 2 YEARS OF THE LEASE AND THEN TRADED FOR A VEHICLE WITH A LARGER INTERIOR. THIS VEHICLE WAS LEASED IN FEBRUARY 2007 DURING THE PRESIDENT'S DAY SALE AT KARL MALONE TOYOTA IN ALBUQUERQUE. THIS VEHICLE CONSISTENTLY "PAUSED" BRAKING FOR MOST OF A SECOND WHEN ONE OF THE FRONT WHEELS PASSED THRU A SMALL POTHOLE ON PAVED ROADS. IT MAY HAVE ALSO HAD THIS BEHAVIOR IN OTHER SITUATIONS, BUT I DIDN'T ENCOUNTER ANY OTHER CASES. I EXPECTED MORE BRAKING MISBEHAVIOR WHEN ALBUQUERQUE INSTALLED SOME REDLIGHT CAMERAS BECAUSE THEY ALSO INSTALLED WARNING STRIPS IN THE PAVEMENT APPROACHING THESE INTERSECTIONS. IN SOME CASES THEY DIDN'T INSTALL STRIPS IN THE FOUR GROOVES CUT IN THE PAVEMENT PERPENDICULAR TO VEHICLE TRAVEL, BUT NEITHER THE GROOVES OR THE STRIPS BOTHERED MY PRIUS DURING BRAKING. MAYBE THAT WAS BECAUSE BOTH WHEELS SAW THE SAME TRANSIENTS. I DIDN'T REPORT THIS TO THE DEALER/MANUFACTURER/GOVERNMENT BECAUSE I CHALKED IT UP TO MORE NONSENSE FROM MODERN ANTI-LOCKING BRAKING SYSTEMS, AND BECAUSE THE BEHAVIOR WAS CONSISTENT/PREDICTABLE AND MOST ANTI-LOCKING SYSTEMS ANNOY ME WITH THEIR BEHAVIOR. WE'VE CONTINUE TO "IMPROVE" ANTI-LOCKING BRAKE SYSTEMS, BUT DIMINISHING MARGINAL RETURNS HAS CAUSED THE IMPROVEMENTS TO ACTUALLY REDUCE THE VALUE OF THESE BRAKING SYSTEMS TO DRIVERS. FOR EXAMPLE, BRAKING DISTANCES IN TYPICAL (I.E. MOST) CONDITIONS ARE LENGTHENED BY THE PREVENTABLE. OVERLY CAUTIOUS ACTIONS OF THESE SYSTEMS. MORE PROBLEMATIC, THESE BRAKING SYSTEMS DO NOT DELIVER THE PERFORMANCE IN URGENT SITUATIONS WHICH THEY SEEM TO PROMISE IN DAY-TO-DAY DRIVING. EVEN BRAKING FOR AN UNEXPECTED YELLOW LIGHT CAN SURPRISE THE DRIVER WITH A FIRMER THAN USUAL PEDAL WHICH THEN REQUIRES MORE EFFORT THAN EXPECTED TO GET THE DESIRED URGENT BRAKING. THE NEEDED BRAKING IS ULTIMATELY AVAILABLE, BUT IT ENDS UP COMING TOO LATE BECAUSE THE DRIVER HAD TO ADJUST HIS ACTIONS. *TR

I'VE OWNED A 2007 PRIUS SINCE IT WAS NEW AND THE PROBLEM THAT I SEE WRITTEN ABOUT FOR THE 2010 MODEL, MOMENTARY LOSS OF BRAKES WHEN HITTING A POTHOLE OR ROUGH ROAD, IS EXACTLY WHAT I FEEL IN MY 2007 AND HAVE SEEN REPORTED BY OTHER DRIVERS FOR VARIOUS YEAR PRIUS'S. THIS PROBLEM IS NOT A 2010 PROBLEM ONLY!!! THIS SYMPTOM HAS BEEN PRESENT SINCE I BOUGHT THE CAR. *TR

I HAVE A 2007 TOYOTA PRIUS AND AM EXPERIENCING BRAKING PROBLEMS SIMILAR TO THE ONES DESCRIBED AS PART OF THE 2010 MODEL RECALL. I HAVE LOST CONTROL OVER THE BRAKES MOMENTARILY SEVERAL TIMES THROUGHOUT THE PAST FEW YEARS OF OWNERSHIP AND CHALKED IT UP TO ADJUSTING TO A NEW MAKE OF A CAR. NOW I REALIZE THAT I AM PART OF A BIGGER PROBLEM, THE EXPERIENCE I HAVE IS NOT NORMAL AND I DO NOT FEEL SAFE. I STRONGLY ENCOURAGE THE NHTSA TO BROADEN THE RECALL TO ALL PRIUS OWNERS WHO ARE EXPERIENCING THE SAME PROBLEM, NOT JUST 2010 MODELS OR THOSE WHOSE VIN NUMBER MATCH UP TO THE COMPUTER SYSTEM. *TR

WHEN ATTEMPTING TO USE THE BRAKES ON MY 2007 TOYOTA PRIUS WHEN DRIVING OVER A BUMPY SURFACE, POTHOLE, ETC., IT TAKES A SHORT DISTANCE OR 1-2 SECONDS FOR THE BRAKES TO TAKE HOLD AND SLOW/STOP THE CAR. IT FEELS AS THOUGH THE CAR LURCHES FORWARD A BIT BEFORE BRAKING AND THE "SLIP INDICATOR" WARNING LIGHT ON THE DASH FLASHES. THIS HAS HAPPENED APPROXIMATELY 10 TIMES SINCE BUYING THE CAR IN APRIL OF 2007. I HAVE NOTIFIED THE ORIGINAL DEALER (TOYOTA OF NORTH HOLLYWOOD), BUT WAS INFORMED THAT THERE IS NO WAY TO CORRECT THE PROBLEM ON MY CAR'S PARTICULAR MODEL. *TR

I OWN A 2007 TOYOTA PRIUS AND HAVE EXPERIENCED OCCASIONAL MOMENTARY LOSS OF BRAKING (MY FOOT FIRMLY ON THE BRAKE PEDAL) WHILE DRIVING OVER A BUMPY SURFACE. WHILE BRAKING OVER SMALL POT HOLES, RAILROAD TRACKS, ROUGH PATCHES, ETC., THE CAR SEEMS TO LUNGE FORWARD APPARENTLY AS THE BRAKES RELEASE FOR A SPLIT SECOND (APPROXIMATELY 1/4 TO 1/2 SECOND). THE ROAD CONDITIONS CAN BE WET OR DRY. AT THE SAME TIME, MY TRACTION CONTROL LIGHT WILL FLASH ON AND OFF UNTIL THE ROAD SMOOTHES OUT. THAT SPLIT SECOND IS ENOUGH TO CAUSE AN ACCIDENT WITH THE CAR IN FRONT OF ME IF I DON'T GIVE MYSELF EXTRA ROOM OR SLOW DOWN PRIOR TO THE BUMPY CONDITION (1/2 SECOND AT 20 MPH = 15 FEET OF UNWANTED TRAVEL). I DRIVE OVER THE SAME RAILROAD TRACKS JUST PRIOR TO A TRAFFIC LIGHT EVERY DAY AND I HAVE HAD TO ADJUST MY DRIVING HABITS TO KEEP THIS DANGEROUS, ADDITIONAL STOPPING DISTANCE FROM RECURRING. THIS HAS OCCURRED APPROXIMATELY 15 TO 20 TIMES IN VARIOUS BUMPY CONDITIONS SINCE I BOUGHT THE CAR OVER 3 YEARS AGO. I HAVE HAD SOME CLOSE CALLS, BUT NO ACCIDENT YET. I HAVE NOT COMPLAINED TO TOYOTA, BUT DUE TO ALL THE COMPLAINTS I HAVE READ ABOUT ONLINE, I ASSUMED THEY WOULD DO SOMETHING EVENTUALLY. *TR

DATE: 02/09/2010 TIME: 10:01:20 CREATION DATE: 02/09/2010 CREATION TIME: 09:58:43 I WOULD LIKE TO REPORT A BRAKING/TRACTION CONTROL/LOSS OF ENGINE POWER SAFETY PROBLEM WITH MY 2007 TOYOTA PRIUS. THE PROBLEM HAPPENS WHILE DRIVING ON SNOW COVERED FLAT ROAD SURFACES (1 INCH OF SNOW), SNOW COVERED HILLY ROADS (1 INCH OF SNOW), AND BUMPY ROAD SURFACES. WHEN THE TRACTION CONTROL SYSTEM (TRAC) ENGAGES ON THESE ROAD SURFACES, I LOSE THE ABILITY TO BRAKE AND ALSO LOSE POWER TO THE ENGINE SIMULTANEOUSLY. I HAVE HAD FOUR (4) NEAR-ACCIDENTS DUE TO THIS SAFETY PROBLEM. 1.SNOW COVERED (1 INCH OF SNOW) GOING DOWNHILL (SLIGHT HILL)- LOST BRAKES AFTER TRAC TRACTION CONTROL SYSTEM ENGAGED WAS UNABLE TO STOP CAR - WENT THROUGH STOP SIGN. CAR WENT ONTO BUSY HIGHWAY (50 MPH ZONE) AND WOULD NOT STOP. LUCKILY NO CARS WERE COMING AND I AVOIDED A VERY SERIOUS ACCIDENT. 2. SNOW COVERED (1 INCH OF SNOW) GOING DOWNHILL - LOST BRAKES AFTER TRAC TRACTION CONTROL SYSTEM ENGAGED AND ALMOST CRASHED INTO CARS THAT WERE SLOWING DOWN AHEAD OF ME. 3. SNOW COVERED (1 INCH OF SNOW) GOING UPHILL - TRAC TRACTION CONTROL SYSTEM ENGAGED AND I LOST ALL ENGINE POWER AS I WAS TURNING LEFT UP A STEEP HILL. I ALMOST CRASHED INTO LARGE ROCKS AT THE ROADSIDE. I WAS ABLE TO AVOID A CRASH. 4. SNOW COVERED (1 INCH OF SNOW) DRIVING ON FLAT ROAD SURFACE. I TURNED OFF OF SNOW COVERED ROAD INTO A PARKING LOT AREA. TRAC TRACTION CONTROL SYSTEM ENGAGED AND I LOST THE ABILITY TO BRAKE. MY CAR WENT AT LEAST 15 FEET IN THE PARKING LOT AREA BEFORE STOPPING. LUCKILY THERE WERE NO PARKED CARS THERE AND I DID NOT HAVE AN ACCIDENT. A RECURRING PROBLEM WITH TRAC AND LOSS OF ENGINE POWER ALSO OCCURS ON THE HILLY ROAD LEADING UP TO MY HOUSE. WHEN THE ROAD IS SNOW COVERED (1 INCH OF SNOW) OR ICY THE TRAC TRACTION CONTROL SYSTEM ENGAGES AND I LOSE ALL POWER TO THE ENGINE. IT MAKES IT NEARLY IMPOSSIBLE TO GET MY CAR UP THE HILL DUE TO THE LOSS OF POWER WHEN TRAC ENGAGES! *TR

I HAVE A 2007 PRIUS. AND I LOVE IT, HOWEVER BEFORE ALL THIS CAME OUT ABOUT PRIUS BRAKES, IN DECEMBER 2009 THE BRAKES STARTED ACTING WEIRD. THEY WOULD NOT ENGAGE WHEN I STEPPED ON THE BRAKE PEDAL AND THEN WOULD JERK TO A STOP A FEW SECONDS LATER. THE FIRST TIME IT HAPPENED MY PASSENGER AND I JUST LOOKED AT EACH OTHER AND COMMENTED ON HOW THAT WAS STRANGE. IT HAS CONTINUED TO HAPPEN USUALLY WHEN I AM GOING SLOW (25MPH) OR LESS, WHEN IT IS DAMP (I LIVE IN OREGON, WHEN IS IT NOT DAMP IN THE WINTER) AND COLD. *TR

I HAVE A 2007 PRIUS. EVERY TIME I HIT A BUMP OR POTHOLE, THE CAR FEELS AIRBORNE, AND THE SKID CONTROL LIGHT COMES ON. THE CAR HAS TERRIBLE TRACTION IN WET OR SNOWY WEATHER. I BELIEVE THAT THE BRAKING SYSTEM ON ALL PRIUS SHOULD BE INVESTIGATED. *TR

WHILE APPROACHING INTERSECTION, OUR 2007 TOYOTA PRIUS FAILED TO STOP. WHILE BRAKING, THE CAR CONTINUED TO ROLL - INTO THE SIDE OF A TRUCK. THE CAR WAS TOTALED. AT THE TIME, WE EXPLAINED THAT THE BRAKES WERE APPLIED, BUT THE CAR FAILED TO STOP. WE ASKED THE INSURANCE COMPANY AND TOYOTA IF THERE WERE ANY REPORTS OF PROBLEMS WITH THE PRIUS, AND WE WERE TOLD "NO REPORTED PROBLEMS" WITH THE CAR. PRIOR TO THE INCIDENT WE HAD JUST HAD THE 25,000 MILE MAINTENANCE DONE SO WE KNEW IT WAS NOT THE BRAKES. ABOUT A YEAR LATER, WE WERE INFORMED OF THE CAR MAT PROBLEM, AND NOW THERE IS TALK OF POSSIBLE ACCELERATOR/ELECTRONIC PROBLEMS. WE NOW HAVE A 2008 PRIUS, AND EXPERIENCE A MOMENTARY LOSS OF THE ELECTRONIC SYSTEM WHEN THE CAR HITS A BUMP. WE CONTACTED TOYOTA LAST WEEK, AND WERE PROMISED A CALLBACK IN TWO DAYS, BUT SO FAR WE HAVE NOT HEARD ANYTHING. SO UNTIL WE GET ASSURANCE THAT OUR CAR IS SAFE, WE HAVE DECIDED TO STOP DRIVING THE PRIUS. SUBSEQUENT TO THE ACCIDENT, MY BACK PAIN WENT FROM MANAGEABLE TO UNBEARABLE, WHICH LED TO SPINE SURGERY IN 1/09. MY PHYSICIANS BELIEVED THAT THE ACCIDENT MIGHT HAVE AGGRAVATED THE SYMPTOMS TO THE POINT THAT I REQUIRED SURGERY - POSSIBLY FROM THE IMPACT FROM THE AIRBAGS. *TR

I HAVE NOTICED THAT WHEN I AM DRIVING OR BRAKING WHILE GOING OVER POT-HOLES, RAILROAD TRACKS, OR VERY BUMPING ROADS I CAN FEEL A SUDDEN AND MOMENTARY LOSS OF BRAKING AND/OR ACCELERATION. I ALSO NOTICED THAT THE TRACTION CONTROL INDICATOR LIGHT ON THE DASH ALWAYS TURNS ON WHEN THIS HAPPENS. I TOOK THE DEALER JUST AFTER I PURCHASED THE VEHICLE AND WAS TOLD THAT EVERYTHING WAS NORMAL. THIS HAS BEEN HAPPENING FOR THE LAST 2 AND A HALF YEARS. IT HAS HAPPENED 3 OR 4 TIMES THIS WEEK ALONE. I HAVE GOTTEN USED TO THIS HAPPENING BUT HAVE ALSO BEEN VERY CONCERNED THAT IT WILL CAUSE A REAREND COLLISION, OR SOMETHING EVEN WORSE. THIS NEEDS ATTENTION ASAP. THANK YOU *TR

THOUGHT IT WAS THE TIRES, SO REPLACED THE ORIGINAL BRIDGESTONES FOR NOKIANS, BUT THE ISSUE STILL OCCURS. THE "SENSATION" IS YOU FEEL LIKE YOU'VE LOST CONTROL OF THE CAR MOMENTARILY. AS A RESULT, I'VE CHANGED MY COMMUTE ROUTE HOME AND DRIVE MUCH SLOWER (WAS ALREADY DRIVING SLOWER SINCE PRIUS MILEAGE IS DEPENDENT ON MPH). ON OCCASIONS, THE SPEED (ON A STRAIGHT AWAY) SET WITH CRUISE CONTROL WILL INCREASE BY ITSELF ... BY A COUPLE MPH .... W/O ME DOING ANYTHING OR TOUCHING ANYTHING. SO I'M FORCED TO TAP BRAKE ........

I OWN A 2007 PRIUS. IT EXPERIENCES A LAPSE IN BRAKING POWER WHEN ON UNEVEN TERRAIN (IE A POTHOLE OR RAILROAD TRACKS). THIS HAS OCCURED NEARLY EVERY SINGLE TIME I HAVE DRIVEN ON AN UNEVEN SURFACE SINCE PURCHASING THE VEHICLE IN EARLY 2007. THE CONSEQUENCE IS A MOMENTARY SURGE IN THE VEHICLE SPEED DURING TIMES THAT I AM ATTEMPTING TO SLOW DOWN-IT IS A FRIGHTENING SITUATION THAT MAKES ONE'S HEART JUMP EVERY TIME IT HAPPENS. I HAVE REPORTED THE ISSUE TO MY DEALERSHIP-THEIR RESPONSE WAS THAT THEY HAVE NOT RECEIVED ANY COMPLAINTS ABOUT THE ISSUE AND THAT THEY WILL WAIT AND SEE WHAT HAPPENS WITH THE ANTICIPATED 2010 MODEL RECALL. THIS APPEARS TO BE THE SAME PROBLEM THAT IS BEING DESCRIBED IN THE 2010 PRIUS.

PRIUS 2007 HYDRAULIC BRAKING/TRACTION CONTROL. THERE IS A DELAYED INTERACTION BETWEEN THE HYDRAULIC BRAKES AND THE TRACTION CONTROL, THAT OVERRIDES THE ACTIONS OR THE DRIVER'S BRAKING, FOR SEVERAL SECONDS. THIS TYPICALLY OCCURS IF THERE IS ANY MOMENTARY LOSS OF TRACTION DUE TO, EVEN A MINOR RIPPLE IN THE ROAD. THE EFFECT IS MOST DANGEROUS AT SPEEDS OVER 40MPH, BECAUSE QUITE SOME DISTANCE IS COVERED BEFORE BRAKING RESUMES. THE TRACTION CONTROL RELINQUISHES HYDRAULIC BRAKING FOR 2-3 SECONDS, BEFORE NORMAL BRAKING ACTION IS RESTORED. THE DELAY APPEARS TO BE SOFTWARE RELATED, AND THE TOYOTA DEALER INSISTED THAT THE BEHAVIOR IS NORMAL. I DISAGREED BUT FOUND NO RELIEF. I ADJUSTED MY DRIVING TO ACCOUNT FOR THIS. *CN

THE TIME SPAN IS SHORT, MAYBE 1-2 SECONDS, BUT THE TRACTION LIGHT COMES ON FOR EVERY INCIDENT.

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...

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 PRESSED ON THE BRAKES IN AN EMERGENCY SITUATION AND THERE WAS A SLIGHT DELAY BETWEEN WHEN THE BRAKE PEDAL WAS DEPRESSED AND WHEN THE BRAKES GRABBED. I ENDED UP STRIKING THE CAR IN FRONT OF ME. I HAVE THE LICENSE PLATE OF THE CAR I HIT ETCHED IN MY FRONT BUMPER. 2007 TOYOTA PRIUS. *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

FOR THE PAST SEVERAL MONTHS, MY 2007 TOYOTA PRIUS HAS EXPERIENCED THE OCCASIONAL LOW SPEED BRAKING PROBLEM THAT HAS BEEN REPORTED IN THE NEWS MEDIA TODAY. I FIRST NOTED THIS WHEN GOING OVER RAILWAY TRACKS AT LOW SPEED WHILE BRAKING. I EXPERIENCED WHAT FELT LIKE A LOSS OF TRACTION BRIEFLY, AND THE ANTI-LOCK BRAKE LIGHT WARNING SYSTEM FLASHED. THIS HAS HAPPENED AGAIN IN LOW SPEED BRAKING SITUATIONS WHILE GOING OVER AN UNEVEN SURFACE SEVERAL TIMES, BUT NOT CONSTANTLY. I REPORT THIS BECAUSE MY PRIUS IS A 2007 MODEL -- NOT A 2010, WHICH INITIAL NEWS REPORTS INDICATED WERE AFFECTED. I AM THE ORIGINAL OWNER. I NOTIFIED THE DEALER (BOB BRIDGE TOYOTA IN RENTON, WA) THIS MORNING. I INITIALLY DID NOT UNDERSTAND THE NATURE OF THE PROBLEM UNTIL I HEARD THE NEWS REPORTS THIS MORNING. *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.

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

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.

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

OBVIOUSLY THERE HAS BEEN A LOT OF MEDIA COVERAGE OVER THE PAST DAY OR SO OVER THE THIRD GENERATION PRIUS AND BRAKE ISSUES. WHILE I HAVE A 2007 PRIUS (SECOND GENERATION), I CAN SAY THAT MY CAR ALSO SUFFERS FROM THE SAME ISSUE WHILE BRAKING ON AN UNEVEN ROAD, GOING OVER A BUMP, ETC. (THIS HAS HAPPENED ON DOZENS OF OCCASIONS). WITH MY FOOT ON THE BRAKE PEDAL, MY CARS FEELS AS IF IT MOMENTARILY LURCHES FORWARD BEFORE THE BRAKES ONCE AGAIN REACT. MY TRACTION-CONTROL LIGHT MOMENTARILY FLASHES ON MY DASHBOARD WHEN THIS HAPPENS. THIS COMMENT FROM A POSTER ON YOUR WEBSITE EXACTLY DESCRIBES MY PROBLEM: "WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND." SINCE MY CAR IS NOT A THIRD GENERATION PRIUS, I FIND IT INTERESTING THAT IT IS SUFFERING FROM THE SAME PROBLEM THAT APPARENTLY ONLY INVOLVES THE NEWEST MODEL. *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

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

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.

I HAVE A 2007 PRIUS THE FOLLOWING HAS OCCURRED ANY TIME DRIVING OVER ROUGH PATCHES OF ROAD OR OVER RR TRACKS: THE CAR LOSES TRACTION AND POWER FOR A SORT TIME UNTIL SMOOTH PAVEMENT RETURNS. THE VSC LAMP ON THE DASH SHOWS UP WHEN THIS HAPPENS. I SHUDDER TO THINK WHAT WOULD OCCUR ON A ROUGH MOUNTAIN ROAD OR IN WET WEATHER. THIS TYPE OF EVENT SOUNDS VERY MUCH LIKE WHAT'S BEING REPORTED BY THE DRIVERS OF THE 2010 PRIUS. IN 47 YEARS OF DRIVING I'VE NEVER HAD A CAR REACT IN THIS WAY. I'VE COMPENSATED BY DRIVING CAUTIOUSLY AND WAIT FOR TRACTION TO RETURN BUT IT DOESN'T FEEL QUITE RIGHT WHEN IT HAPPENS. *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

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

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.

ON FRIDAY, DECEMBER 4, 2009 AT ABOUT 4:15 PM, I HAD A SUDDEN ACCELERATION INCIDENT WITH MY 2007 TOYOTA PRIUS. I HAD NOT HAD ANY PRIOR DIFFICULTY WITH THIS VEHICLE IN THE APPROXIMATELY 34,000 MILES I HAD DRIVEN SINCE I BOUGHT IT NEW. HOWEVER AT THIS TIME WHEN I TRIED TO BACK THE CAR ABOUT 50 FEET BACKWARDS INTO A MOTEL PARKING SPOT (ACTUALLY THERE WERE 3 OPEN SPOTS IN A ROW), IT RESPONDED VERY ABNORMALLY. I STARTED THE CAR, PUT IT IN REVERSE AND GENTLY APPLIED PRESSURE TO THE GAS PEDAL. INSTEAD OF CREEPING BACKWARDS AT ~5 MPH AS I HAD INTENDED, THE CAR "TOOK OFF" AT ABOUT 30-40 MPH. I STOMPED ON THE BRAKES WITH BOTH FEET AND INITIALLY DIDN'T SLOW DOWN. I FELT AN IMPACT AS MY CAR GRAZED A PARKED VEHICLE. MY CAR JUMPED OVER THE CURB AT THE PARKING LOT EDGE, PASSED OVER SOME SHORT BUSHES AND ENTERED A CULVERT. SOMEHOW I WAS ABLE TO TURN THE CAR AND IT CARVED A 180 DEGREE CURVE AND CAME TO A HALT ABOUT 75 FEET AFTER IT PASSED INTO THE CULVERT. FORTUNATELY I DID MAKE THIS SHARP TURN SINCE THERE IS A 4 LANE HIGHWAY ON THE OTHER SIDE OF THE CULVERT. THERE WERE NO INJURIES AND ONLY SLIGHT DAMAGE TO THE OTHER CAR, BUT AN ESTIMATED $7000 OF BODY DAMAGE TO MY CAR. THE POLICE WERE CALLED AS WELL MY INSURANCE COMPANY. THE OWNER OF THE OTHER VEHICLE WAS LOCATED. MY CAR WAS TOWED TO A LOCAL TOYOTA DEALERSHIP. SINCE THAT TIME, THE LOCAL TOYOTA REGIONAL OFFICE SENT OUT A REPRESENTATIVE WHO INSPECTED MY CAR AND "DURING A ROAD TEST NO ABNORMAL BRAKING OR ACCELERATION PROBLEMS WERE FOUND." I HAVE SINCE BEEN IN CONTACT WITH TOYOTA USA IN TORRANCE , CA. I HAVE SPOKEN WITH A "CASE REPRESENTATIVE" WHO HAS NOT BEEN HELPFUL. FINALLY AFTER 5 OR 6 PHONE CALLS, I WAS ABLE TO GET THE ADDRESS OF THE LEGAL DEPARTMENT. I WROTE THEM A LETTER ON JANUARY 20 AND HAVE HEARD NOTHING FROM THEM. I ALSO CALLED AND LEFT MESSAGES ON FEBRUARY 2 AND 4. AS A PHYSICIAN INTERESTED IN PUBLIC HEALTH I DON'T WANT MY FAMILY OR ANYONE ELSE TO DRIVE THIS CAR. MY FAITH IN THE TOYOTA COMPANY IS DIMINISHED.*JB

WHEN IT IS HUMID AND/OR RAINING, THE REAR BRAKES OF MY 2007 TOYOTA PRIUS SEIZE UP AS I COME TO A STOP. JUST BEFORE A STOP (IE AT A STOP SIGN OR STOP LIGHT) THE BRAKES WILL SEEM TO GRAB REALLY HARD IN THE BACK AND THE CAR WILL SORT OF LURCH OR JERK FORWARD BUT BE ABRUPTLY HELD IN PLACE BY THE REAR. THERE IS A LOUD NOISE FROM THE BACK LIKE A RUBBING NOISE WHEN THIS HAPPENS. THE CAR HAS BEEN TO TWO TOYOTA DEALERSHIPS BOTH OF WHICH DENY THAT THIS COULD BE OCCURRING. I INSISTED THAT IT BE LOOKED AT AND TEST DRIVEN AND THE MECHANIC CLAIMS THERE IS NOTHING WRONG. THIS HAS BEEN GOING ON SINCE I FIRST BOUGHT THE CAR IN MAY, 2008. PASSENGERS HAVE WITNESSED THIS IN THE CAR. IT ONLY HAPPENS WHEN IT IS SERIOUSLY HUMID (IE ON THE VERGE OF RAINING) OR WHEN IT IS RAINING....EVERY TIME I APPROACH A STOP, WITHOUT EXCEPTION. IT'S LIKE THE REAR OF THE CAR IS SUDDENLY SUPERGLUED TO THE ROAD AND THE BODY OF THE CAR/SHELL OF THE CAR CONTINUES WITH THE FORWARD MOMENTUM/MOTION. FOR THE CATEGORY OF PROBLEM I CHECKED SERVICE BRAKE, HYDRAULIC, BECAUSE THAT WAS THE ONLY "BRAKE" OPTION I SAW BESIDES PARKING BRAKE. I HAVE NO IDEA IF THIS IS THE CORRECT CATEGORY. *TR

2007 TOYOTA PRIUS - BRAKES IF DRIVING OVER A POT HOLE, BUMP, OR ANY OTHER NON-FLAT SURFACE, THE BRAKES DO NOT WORK, THE CAR THRUSTS FORWARD, & THE "ABS" LIGHT FLASHES. THIS IS LIKELY THE CAUSE OF AN ACCIDENT I HAD SLIPPING OFF THE ROAD APPROXIMATELY A YEAR AND A HALF AGO. *TR

I HAD A 2007 TOYOTA PRIUS THAT SEEMED TO HAVE ISSUES WHENEVER I WOULD HIT THE BRAKES ON SLICK\WET ROADS OR SOMETIMES WHEN I WOULD HIT A BUMP. IT FELT AS IF THE BRAKES WOULD NOT APPLY AND THE CAR WOULD FEEL LIKE IT ACCELERATED FORWARD INSTEAD OF STOPPING. USUALLY THE BRAKES WOULD KICK IN AFTER A SECOND OR TWO OF THIS KIND OF SLIPPING. HOWEVER, IN EARLY NOVEMBER OF THIS YEAR WHILE TAKING MY SON TO KARATE ON A WET DAY WE HIT A SPOT OF REPAIRED ROAD THAT CAUSED THIS TO OCCUR AGAIN, INSTEAD OF CORRECTING ITSELF IT FELT LIKE I HAD NO CONTROL OF THE CAR AND THE CAR VEERED OFF TO THE SIDE OF THE ROAD, WENT UP AN INCLINE AND FLIPPED THE CAR ONTO ITS SIDE. FORTUNATELY IN THIS CASE NO ONE WAS INJURED AT ALL AS I WAS GOING FAIRLY SLOW AND THE CAR QUICKLY CAME TO A STOP WHEN IT WENT ON IT SIDE. I ALWAYS THOUGHT THE ISSUE WAS WITH THE ANTI-LOCK BRAKE SYSTEM BUT I RECENTLY SAW AN ARTICLE ABOUT 2010 PRIUS HAVING THIS ISSUE AND I THOUGHT I SHOULD REPORT THAT THIS HAPPENED TO ME ON AN OLDER VERSION OF THE PRIUS AS WELL. *TR

I JUST FOUND OUT TODAY ABOUT THIS METHOD OF REPORTING A COMPLAINT, OTHERWISE I WOULD HAVE REPORTED IT A LONG TIME AGO. *TR

THIS DESCRIPTION IS OF AN OCCURRENCE WHICH MAY BE A THE RESULT OF A FLAW. UPON LIGHT PRESSURE ON THE BRAKE PEDAL, WHILE PROCEEDING OVER AREAS WITH SUSPECT TRACTION, VEHICLE SEEMS TO LOSE ALL BRAKING FOR A SMALL BUT UN-NERVING MOMENT. IT IS AS THOUGH THE ABS IS FIGHTING THE REGENERATIVE BRAKING OF THE HYBRID DRIVE. *TR

THE INCIDENT I'M REPORTING TOOK PLACE WHILE DRIVING MY PRIUS HOME DURING A FREEZING RAIN AND HAD TWO OTHER PASSENGERS IN THE CAR. WE WERE GOING ABOUT 15MPH ON SUBURBAN ROADS DUE TO THE TREACHEROUS CONDITIONS. SINCE A T INTERSECTION LAY AHEAD (MAYBE 100 FT) I VERY SLOWLY AND CAUTIOUSLY STARTED TO TRY TO ENGAGE THE BRAKES WELL IN ADVANCE IN ORDER TO AVOID ANY SKIDDING. HOWEVER, *MY BRAKES DID NOT RESPOND AT ALL* AND NEITHER THE ABS SYSTEM OR THE SKID-WARNING LIGHT WENT ON AS THE CAR REFUSED TO STOP. RATHER, THE CAR SIMPLY KEPT DRIVING. SINCE I HAD GIVEN MYSELF AMPLE TIME PRIOR TO THE STOP I WAS ABLE TO ASSESS THE SITUATION AND AM VERY SURE THAT THIS IS WHAT HAPPENED AND TOLD MY HUSBAND, WHO WAS A PASSENGER, THAT MY BRAKES WERE NOT RESPONDING AT ALL. WHEN WE REACHED THE INTERSECTION I WAS ABLE TO TURN THE CAR TO THE RIGHT ON TOP OF GRAVEL AND DIRT, WHEN THE BRAKES ENGAGED AND WE CAME TO A HALT. THE CONDITIONS REMAINED ICY AND WE TESTED THE BRAKES A NUMBER OF TIMES ON OUR DRIVE HOME TO SEE IF WE COULD REPLICATE WHAT HAD HAPPENED BUT WERE UNABLE TO REPRODUCE THE PROBLEM. ALTHOUGH ICY, THE BRAKES WORKED AS WELL AS ONE MIGHT EXPECT UNDER THE CIRCUMSTANCES. ALSO, ABS AND THE SKID-WARNING LIGHT WENT ON NORMALLY THEREAFTER. I CALLED OUT DEALERSHIP WHO URGED US TO BRING IN THE VEHICLE FOR INSPECTION AND I PLAN TO DO SO THIS WEEK. I HAVE ALSO REPORTED THE PROBLEM TO TOYOTA. *TR

I OWN A 2007 TOYOTA PRIUS AND I HAVE NOTICED THAT IF I AM BRAKING AND HIT A BUMP OR A POTHOLE, THAT THE BRAKING SEEMS TO PAUSE AND I HAVE TO BRAKE HARDER.

FORTUNATELY, I WAS NEVER IN A POSITION TO ENDANGER MYSELF OR ANOTHER, BUT IN OTHER CIRCUMSTANCES IT COULD HAVE BEEN A PROBLEM. *TR

I HAVE A 2007 TOYOTA PRIUS. WHEN BRAKING, THE BRAKES FEEL "TACKY" AND/OR THERE IS A JUDDER FEELING, WHICH MAKES THE CAR STOP SUDDENLY OR ABRUPTLY.

FROM THE BEGINNING, MY 2007 PRIUS (PURCHASED 5/19/07) HAS CONSISTENTLY LOST BRAKING POWER BRIEFLY IF I HIT A SMALL BUMP IN THE ROAD AS I AM BRAKING, AT LOW SPEED, FOR A STOP SIGN OR TRAFFIC LIGHT.

I AM WRITING TO REPORT TRANSIENT FAILURE OF THE ANTI-LOCK BRAKING SYSTEM IN OUR 2007 TOYOTA PRIUS. SINCE MAY 2008 WE HAVE NOTICED EPISODIC ACCELERATIONS DURING LIGHT BRAKING (AT INTERSECTIONS FOR INSTANCE) WHEN THE CAR ENCOUNTERS POT HOLES, GRATES, RAILROAD TRACKS OR SLIPPERY PAVEMENT. WE SEEM TO LOSE CONTROL OF THE VEHICLE MOMENTARILY. ONLY WITH HEAVY BRAKE PEDAL DEPRESSION DOES THE VEHICLE COME TO A COMPLETE STOP. UNTIL JANUARY 2010 WE THOUGHT THIS WAS A UNIQUE FEATURE TO OUR VEHICLE AND WE WERE HYPERSENSITIVE TO ITS IDIOSYNCRASIES. UNFORTUNATELY, IN JANUARY 2009 THIS DEFECT LEAD TO A LOW SPEED MOTOR VEHICLE COLLISION WHEREIN MY WIFE WAS UNABLE TO STOP THE VEHICLE WHEN ANOTHER DRIVER ABRUPTLY PULLED IN FRONT OF HER. NO ONE WAS HURT, THANKFULLY, BUT BOTH VEHICLES WERE DAMAGED. ALL OTHER NEARBY DRIVERS WERE ABLE TO STOP IN TIME AND NO OTHER COLLISIONS OCCURRED. ON DECEMBER 4, 2009 THIS SAME VEHICLE WAS INVOLVED IN ANOTHER LOW SPEED MOTOR VEHICLE COLLISION WHEN A DRIVER AHEAD SUDDENLY STOPPED TO AVOID A PEDESTRIAN. THE PRIUS WAS UNABLE TO STOP IN TIME (EVEN UNDER HEAVY BRAKE PEDAL PRESSURE) AND COLLIDED WITH REAR BUMPER OF THE CAR AHEAD. MORE THAN $5,000 IN DAMAGE OCCURRED TO THE PRIUS ALONE; THOUGH NO ONE WAS HURT. IN BOTH INSTANCES NEARBY AND SUBSEQUENT VEHICLES EXPERIENCED NO PROBLEMS STOPPING. THERE WERE NO SIGNS OF ICE OR SLIPPERY PAVEMENT EITHER TIME. FURTHERMORE, NEITHER MY WIFE NOR I HAVE EVER BEEN INVOLVED IN ACCIDENTS IN THE PAST OR WITH OTHER CARS. WE DIDN'T RECOGNIZE THAT THIS COULD BE A MANUFACTURER'S DEFECT UNTIL COMPLAINTS TO THE NHTSA BECAME PUBLIC AND WIDELY DISCUSSED IN DECEMBER 09 & JANUARY '10. PLEASE NOTE, HOWEVER; OUR AFFECTED VEHICLE IS A 2007 MODEL YEAR AND WE HAVE EXPERIENCED SYMPTOMS INCLUDING LOSS OF CONTROL AND INAPPROPRIATE ACCELERATION JUST AS DESCRIBED BY OTHERS IN THE ONLINE COMMUNITY FOR 2010. *TR

I WAS DRIVING MY 2007 TOYOTA PRIUS IN HEAVY RUSH HOUR TRAFFIC AND COLD, WET SNOWY CONDITIONS THIS PAST FRIDAY NIGHT. MY BRAKES FAILED TO ENGAGE TWICE. THE FIRST TIME I WAS GOING 5-10 MPH AND STEPPED ON THE BRAKE TO MAINTAIN A SAFE FOLLOWING DISTANCE WITH THE CAR IN FRONT OF ME, WHICH HAD STOPPED. IT WAS AS IF THE CAR WAS IN NEUTRAL AND A YELLOW LIGHT STARTED FLASHING ON THE DASHBOARD (I THINK THIS WAS THE ABS SYSTEM LIGHT, BUT I DON'T KNOW) AND I FORTUNATELY COASTED TO A STOP BEFORE HITTING THE CAR IN FRONT OF ME. THERE WAS NO SKIDDING OR SLIDING, JUST A NON-RESPONSE FROM THE BRAKES. THE SECOND TIME OCCURRED ABOUT 10 MINUTES LATER AND I WAS AGAIN TRAVELING AT SLOW SPEED AND ATTEMPTED TO BRAKE TO STAY A SAFE DISTANCE FROM THE CAR AHEAD. THIS TIME I REPEATEDLY PRESSED HARD ON THE BRAKE AND INITIALLY THERE WAS NO ENGAGEMENT AND THEN AFTER APPROX 5 SEC THE BRAKES DID ENGAGE AND I AGAIN WAS ABLE TO AVOID A FENDER BENDER. I DROVE THE CAR HOME (WHITE-KNUCKLED) AND IT HAS BEEN PARKED IN MY DRIVEWAY OVER THE WEEKEND - WE EXPERIENCED A MAJOR SNOWSTORM AND I HAVE NOT BEEN ABLE TO DRIVE ANYWHERE. TOMORROW I AM GOING TO SEE IF I CAN GET THE CAR TOWED TO A DEALERSHIP BECAUSE I DON'T WANT TO DRIVE IT. *TR

I WAS DRIVING AT LOW SPEED IN COLD WEATHER, UNDER 20 MPH. I LIGHTLY ACCELERATED TO GET THROUGH AN INTERSECTION, THEN APPLIED THE BRAKES TO STOP BECAUSE OF A CAR STOPPED IN THE LANE AHEAD. THERE WAS ABSOLUTELY NO RESPONSE FROM THE BRAKES SO I RAN INTO CAR IN FRONT. THERE WAS HEAVY DAMAGE TO MY CAR (ESTIMATED AT $4,000 TO $5,000), VERY LITTLE TO CAR IN FRONT (LESS THAN $500). THIS IS THE ONLY TIME THIS HAPPENED. THE BRAKES WORKED FINE FOR 2 YEARS, AND HAVE WORKED FINE SINCE ALTHOUGH I HAVE ONLY DRIVEN THE CAR TO THE DEALERSHIP FOR CHECKING THE BRAKES AND TO GET THE BODYWORK REPAIRED. THE DEALERSHIP CHECKED BRAKES, STATED THAT THERE IS ABSOLUTELY NOTHING WRONG (MECHANICALLY) WITH THE BRAKES. TOYOTA HAD A REGIONAL REPRESENTATIVE INVESTIGATE, AND TOYOTA LEGAL OFFICIALLY BLAMES IT ON ME NOT APPLYING BRAKES IN TIME. I HAVE BEEN TRAINED TO DRIVE ON THE TEST TRACKS AT GM'S MILFORD PROVING GROUNDS, AND HAVE WORKED ON ENGINE AND TRANSMISSION SOFTWARE FOR 14 YEARS, AND HAVE DONE A LOT OF TESTING ON THE TRACK AND ROAD. I KNOW HOW TO APPLY BRAKES, AND I KNOW THEY DID NOT WORK. SINCE THE BRAKES ARE NOT JUST THE MECHANICAL APPARATUS, I SUSPECT A COMPUTER PROBLEM. *TR

2007 TOYOTA PRIUS WITH BRAKE PROBLEMS. CONSUMER STATES THAT THE BRAKES WERE PRESSED AND THE VEHICLE CONTINUED TO MOVE BACKWARD SLOWLY. HE ALSO STATES THAT THE VEHICLE DIDN'T STOP WHEN BRAKES WERE DEPRESSED AND CONSEQUENTLY HIT A STOPPED CAR. *KB

THIS INCIDENT INVOLVES MY 2007 TOYOTA PRIUS HYBRID THAT I HAVE OWNED FOR ALMOST A YEAR. AS I WAS DRIVING APPROXIMATELY 40 MPH AND PUT MY FOOT ON THE BRAKE AS I APPROACHED A RED LIGHT, THE RED BRAKE WARNING CAME ON THE DASH AS DID THE ABS WARNING LIGHT. MY FOOT WENT ALL THE WAY TO THE FLOOR AND I HAD NO BRAKES. LUCKILY I HAD A RIGHT TURNING LANE THAT I COULD VEER INTO AND NOT HIT THE STOPPED VEHICLES IN FRONT OF ME. AS I CONTINUED TO PUSH THE BRAKE TO THE FLOOR AND MANEUVER THE VEHICLE OUT OF TRAFFIC, IT SEEMED TO CATCH A LITTLE AND I WAS ABLE TO SLOW THE VEHICLE EVENTUALLY TO A STOP. I PUT THE VEHICLE IN PARK AS IT WAS STILL RUNNING, AND PULLED OUT THE OWNER'S MANUAL. THE MANUAL SPECIFICALLY STATED THAT IF THESE TWO WARNING LIGHTS CAME ON AT THE SAME TIME, YOU WERE TO "STOP IMMEDIATELY AND CONTACT YOUR TOYOTA DEALERSHIP". THIS IS EXACTLY WHAT I DID. I HAD THE VEHICLE TOWED INTO THEIR FACILITY THAT EVENING. THE NEXT DAY I WAS INTERROGATED BY THE MECHANIC AFTER A DIAGNOSTIC REPORT WAS DONE ON MY CAR. HE WANTED TO KNOW WHEN I LET THE CAR RUN OUT OF GAS. I HAVE NEVER LET MY CAR RUN OUT OF GAS, AND IN FACT THAT JUST FILLED THE TAKE THE DAY BEFORE THIS INCIDENT OCCURRED. THE MECHANIC COULDN'T TELL ME WHAT WAS WRONG AND CONTACTED TOYOTA'S CORPORATE OFFICE. TWO DAYS LATER, I WAS ADVISED THAT THE REASON THE BRAKES DIDN'T WORK WAS BECAUSE I "LET THE CAR RUN OUT OF GAS "AND THIS CAUSED THE ENGINE TO SHUT OFF. I ARGUED THAT THE CAR HAD NEVER RUN OUT OF GAS AND THE ENGINE DIDN'T SHUT OFF, THE BRAKES WENT OUT. THE SERVICE MANAGER PULLED OUT THE DIAGNOSTIC TEST SHOWING THAT "AT SOME POINT" THE CAR HAD RUN OUT OF GAS----THIS TEST DOESN'T GIVE A DATE OF WHEN THIS MAY HAVE HAPPENED. I ADVISED THE SERVICE MANAGER THAT THE CAR HAD 223 MILES ON IT WHEN I PURCHASED IT-- THIS TEST RESULT COULD HAVE HAPPENED WHEN THE CAR WAS STILL AT THE DEALERSHIP, NOT IN MY POSSESSION. THE SERVICE MANAGER ADVISED ME THAT HIS "HANDS WERE TIED" AND THAT TOYOTA HAD MADE THEIR DECISION. *TR

WHILE BACKING OUT OF MY PARKING SPACE AT WORK, MY BRAKES WENT TO THE FLOOR AND BARELY STOPPED THE VEHICLE. ALARM WAS GOING OFF, SO I PULLED FORWARD JUST ENOUGH TO SEE IF THE BRAKES WERE WORKING AT ALL AND THEY WERE PROBABLY 98% GONE. I PARKED, GOT TOWED TO DEALER NEAR MY HOME WITH AAA. I LATER FOUND OUT THAT A PAIR OF ABS SKID CONTROL RELAYS (2 88263-21010) CAUSED THE PROBLEM. NOTHING MECHANICAL FAILED. THESE RELAYS CAUSED MY ENTIRE BRAKING ABILITY TO BE LOST. I BELIEVE THIS IS AN UNSAFE DESIGN AS THERE IS NO MECHANICAL CONNECTION AVAILABLE AT THE PEDAL IF YOU HAVE THIS ELECTRICAL PROBLEM. SOME MECHANICAL BRAKES SHOULD BE AVAILABLE. THE EMERGENCY BRAKE IS ON / OFF ONLY AND NO IN BETWEEN. I WOULD LIKE TO FIND WHAT LEGAL REMEDIES ARE AVAILABLE TO ME AS I AM CONSIDERING CHANGING TO A SAFER VEHICLE DUE TO THIS DESIGN FLAW. AS IN POWER BRAKES, IF YOU LOSE THE POWER BRAKES, YOU CAN STILL STOP THE VEHICLE, THOUGH DIFFICULT SINCE THERE IS STILL A MECHANICAL HYDRAULIC SYSTEM IN PLACE EVEN WITH A FAILED POWER BOOSTER. *TR THE CONSUMER ALSO STATED THE MASTER CYLINDER FAILED.

DRIVING ON A RESIDENTIAL STREET, SPEED LIMIT OF 35MPH, AT 5:20PM IN EVENING COMMUTE TRAFFIC, A NORMAL STOP TRANSITIONED INTO AN EMERGENCY STOP ATTEMPT AND MINOR ACCIDENT. WHEN THE BRAKE PEDAL WAS DEPRESSED, DID NOT SEEM TO SLOW. UPON HARD BRAKING, BRAKE PEDAL ALL THE WAY TO THE BRAKE STOP, NO ABS SHIMMY OR INCREASED SLOWING. (I HAVE NEVER NOTICED BRAKES GOING ALL THE WAY TO THE BRAKE STOP BEFORE, BUT IT HAPPENED THE FOLLOWING DAY WHEN DRIVING TO BODY SHOP FOR ESTIMATE) HIT A 2007 TOYOTA TACOMA WITH TOW PACKAGE. FRONT END DAMAGE OF 2007 TOYOTA PRIUS ESTIMATED AT LEAST $3K. NO DAMAGE TO TACOMA. SAN JOSE PD TOOK REPORT AND WITH NO FLUIDS LEAKING, I DROVE THE CAR HOME AFTER THE ACCIDENT. I REPORTED ACCIDENT TO MY INSURANCE COMPANY AND THEN CONTACT TOYOTA CUSTOMER SERVICE THE FOLLOWING DAY. AS PREVIOUSLY STATED, I DROVE TO LOCAL BODY SHOP FOR REPAIR ESTIMATE AND BRAKES HIT BRAKE STOP AGAIN (GOING LESS THAN 20MPH). TOYOTA CREATED CASE FILE AND TODAY (10/05/07) REGIONAL TOYOTA INSPECTOR IS CURRENTLY INSPECTING MY VEHICLE AT THE LOCAL TOYOTA DEALERSHIP. *TR

TL*THE CONTACT OWNS A 2007 TOYOTA PRIUS. THE CONTACT STATED THAT HIS COMPLAINT PERTAINS TO THE ANTI-LOCK BRAKING SYSTEM ON ALL VEHICLES. HE STATED THAT WHEN DRIVING ON A ROAD THAT IS WET, ICY, OR CONTAINS SNOW, HE HAS TO SLAM ON THE BRAKES AND DEPRESS THE BRAKE PEDAL TO THE FLOOR IN ORDER TO STOP THE VEHICLE. HE STATED THAT THE TIRES LOCK UP ONE BY ONE, WHICH TAKES ALL CONTROL OF STOPPING THE VEHICLE OUT OF HIS HANDS, AS OPPOSED TO PUMPING THE BRAKES AND MAINTAINING SOME CONTROL OVER THE VEHICLE. WHEN THE ABS IS ACTIVATED, THE VEHICLE SHAKES, BUCKS, WIGGLES, JERKS, AND MAKES A LOT OF NOISE. THE CONTACT DID NOT WANT TO PROVIDE ANY VEHICLE INFORMATION OTHER THAN THE YEAR, MAKE, MODEL, AND MILEAGE INFORMATION. THE CURRENT MILEAGE IS 4,000 AND FAILURE MILEAGE WAS 3,000.

WHEN ATTEMPTING AN EMERGENCY STOP, THE BRAKES FAILED TO OPERATE AS EXPECTED. THERE WAS NO FEELING OF ANY BRAKING, AND THERE WAS NO SURGE TO INDICATE THAT THE ABS WAS OPERATING. THE EXPERIENCE WAS SIMILAR TO THOSE REPORTED ON THE WEB PAGE HTTP://WWW.HYBRIDCARS.COM/FORUMS/BRAKE-FAILURE-2007-T1013.HTML?S=500A78277EA2CB675FAC1F9567000BEE&AMP; I HAVE TAKEN IT TO A PRIUS DEALER, AVONDALE TOYOTA, BUT IN THE ABSENCE OF ANY COMPUTER CODES AND THE FACT THAT SUBSEQUENT TESTS OF THE ABS SYSTEM DID NOT INDICATE A PROBLEM THEY WERE UNABLE TO OFFER ANY KIND OF EXPLANATION OR REPAIR. I HAD APPROXIMATELY THREE TO FOUR CAR LENGTHS FROM ME TO THE NEXT CAR AT ABOUT 30 MPH, ENOUGH SPACE THAT I BELIEVE I SHOULD HAVE BEEN ABLE TO BRAKE WITHOUT COLLISION. WHEN I WENT FROM ACCELERATING TO RAPID BRAKING THERE WAS NO REAL SENSATION OF THE CAR SLOWING DOWN MORE THAN SLIGHT BRAKING. THE OTHER CAR HAD MINIMAL DAMAGE, BUT THE DRIVER OF THE OTHER CAR DID HIT HER HEAD ON HER STEERING WHEEL. I HAD CLOSE TO $3,000 IN DAMAGE TO MY FRONT END (HOOD BUMPER AND LEFT FENDER). *TR THE CONSUMER WAS INFORMED THAT THERE WAS NOTHING WRONG WITH THE BRAKES DESIGN. THE BRAKES ARE ELECTRONICALLY ASSISTED AND THAT THE COMPUTER WILL FIRST ATTEMPT TO USE THE ELECTRIC MOTOR FOR INITIAL BRAKING, THEN ENGAGE THE HYDRAULIC SYSTEM AND FINALLY THE ABS BASED ON FEEDBACK FROM VARIOUS SENSORS. THE MECHANIC DID AGREE, THAT IS POSSIBLE THAT WHILE THE COMPUTER IS EVALUATING THE BRAKING EFFICIENCY, A DELAY BETWEEN THE MOTOR ONLY BRAKING AND FULLY ENGAGING THE HYDRAULICS AND ABS ARE POSSIBLE AND PART OF THE DESIGN.
