2005 TOYOTA PRIUS Service Brakes, Hydraulic Problems

TL* THE CONTACT OWNS A 2005 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 15 MPH DURING INCLEMENT WEATHER, THE BRAKE PEDAL WAS DEPRESSED AND THE VEHICLE JERKED INTERMITTENTLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE BRAKE PADS NEEDED TO BE REALIGNED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 133,000.

TL* THE CONTACT OWNS A 2005 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 25 MPH, THE VEHICLE MADE A LOUD POPPING NOISE. THE CONTACT NOTICED THAT THE STEERING WHEEL WAS TILTED AND THE ANTI SKID AND ANTI LOCK BRAKING SYSTEM WARNING INDICATORS ILLUMINATED. WHEN THE CONTACT ATTEMPTED TO MERGE TO THE EMERGENCY LANE, THE STEERING WHEEL SEPARATED FROM THE STEERING COLUMN AND CAUSED A COMPLETE LOSS OF STEERING ABILITY. THE VEHICLE WAS TOWED TO THE DEALER AND THE TECHNICIAN STATED THAT THE FAILURE WAS UNRELATED TO NHTSA CAMPAIGN NUMBER: 12V537000 (STEERING). THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 103,000. *DT*JB

WHILE SLOWING OUR 2005 PRIUS TO MAKE A TURN INTO A PARKING LOT THE BRAKES FAILED TO RESPOND NORMALLY. WARNING LIGHTS CAME ON TO INDICATE THE ABS/VSC HAD A PROBLEM. TOOK IT TO A REPAIR SHOP TO HAVE IT DIAGNOSED, DRIVING IT TO THE SHOP WAS HAZARDOUS, VERY TOUCHY AND SCARY TO DRIVE. THEY SAID IT NEEDED A COMPUTER ASSEMBLY, SKID CONTROL AND STROKE SENSOR ASSEMBLY TO REPAIR THE PROBLEM. OVER $2000 IN PARTS ALONE. CONSIDERING MY OPTIONS NOW. SELL AND NEVER BUY TOYOTA AGAIN WOULD BE ONE OPTION. IF THIS HAD HAPPENED AT HIGHWAY SPEED AND WE NEEDED TO SLOW OR STOP QUICKLY WE MAY HAVE HAD AN ACCIDENT! (ISSUE NOT COVERED BY WARRANTY) ISSUES LIKE LABELS FOR TIRE LOADS COVERED, RIDICULOUS!

TRACTION CONTROL ENGAGED ON A HILL WITH LIGHT SNOW COVER COMPLETELY STOPPING THE WHEELS AND PREVENTING ANY FORWARD MOTION, CREATING A DANGEROUS SITUATION. PEDESTRIANS HAD TO PUSH THE CAR UP THE HILL WHILE THE ACCELERATOR WAS PRESSED TO GET TO THE TOP. BACKING WOULD HAVE PLACED THE CAR IN A DANGEROUS POSITION WITH ONCOMING 50 MPH CROSS TRAFFIC . THERE SHOULD BE AN OVERRIDE FOR SITUATIONS SUCH AS THIS TO ENABLE SOME FORWARD MOTION TO BE MAINTAINED EVEN IF THERE IS SOME WHEEL SLIPPAGE. OCCURRED FRIDAY 14 FEB 2014. THIS HAS OCCURRED IN THE PAST ON GRAVEL DRIVEWAYS AND OTHER ROADS. THIS INSTANCE WAS BY FAR THE MOST TROUBLING SINCE PEDESTRIANS WERE INVOLVED. *TR

I WAS ON THE FREEWAY FAR RIGHT LANE MOVING ONTO AN INTERCHANGE TO ANOTHER FREEWAY WHEN TRAFFIC SUDDENLY STOPPED AHEAD. I SLOWED IN PREPARATION TO STOP WITH PLENTY ROOM TO DO SO. THE CAR BEHIND ME WAS TOO CLOSE AND REAR ENDED MY CAR. AFTER THE IMPACT, MY BRAKES FAILED AND I RAN INTO THE CAR AHEAD EVEN THOUGH I SHOULD HAVE BEEN ABLE TO STOP IN TIME, CAUSING SIGNIFICANT DAMAGE TO THE FRONT OF MY CAR IN ADDITION TO THE REAR DAMAGE. *TR *JS

I ROLLED SLOWLY (<1 MPH) UPHILL TO THE PARKING SLOT (L.A. CODE, 2%GRADE DOWN AWAY FROM BUILDINGS) UP TO THE PARKING CEMENT STOP, AND WAS READY TO SHUT IT DOWN. THE ENGINE STARTED TO RACE, ABOUT TO GO OVER THE CEMENT STOP WHEN I PUT MY FOOT ON THE BRAKE. THE CAR CONTINUED OVER THE CEMENT STOP. I PUSHED HARDER ON THE BRAKE AND THE CAR STARTED TO DRIVE OVER THE SIDEWALK. THEN THE CAR DROVE THROUGH THE PLATE GLASS OF THE STUDIO AND THEN CAME TO A STOP INSIDE. I PUT THE CAR INTO NEUTRAL AND TRIED TO TURN THE CAR 'OFF'. THE CAR'S ENGINE WAS STILL ON AFTER SEVERAL TRIES TO TURN IT OFF AND I HAD MY FOOT OFF THE BRAKE AND ON THE FLOOR. THEN THE CAR TOOK A TURN TO THE LEFT AND DROVE THROUGH THE WALL (MY FOOT WAS STILL ON THE FLOOR). I GOT OUT OF THE CAR WITHOUT TAKING IT OUT OF NEUTRAL AND IT WAS STILL "ON". I TOOK THE KEY WITH ME TO THE MIDDLE OF THE ROOM (I USED THE KEYLESS IGNITION) SO THE CAR SHOULD HAVE "CHIMED" BECAUSE; THE PASSENGER SIDE DOOR WAS OPEN, I WAS OUT OF THE CAR, AND THE CAR WAS STILL LEFT "ON". HOWEVER, THE CAR DID NOT CHIME (INDICATING IT DID NOT DETECT I WAS 12 FEET AWAY). MY TEACHER CAME UP TO THE SHATTERED GLASS WINDOW OF THE STUDIO AT THE SAME TIME THE SECURITY OFFICER FOR THE MINI MALL A FEW MINUTES AFTER I GOT OUT OF THE CAR. I WAS LOOKING FOR MY INSURANCE CARD IN MY PURSE WHEN THE THREE OF US WITNESSED THE CAR "REV" AGAIN AND THE WALL BEGAN TO SHATTER WITH PLASTER AND WOODEN STUDS FALLING AROUND THE CAR WITH NO ONE DRIVING (THE CAR WAS IN NEUTRAL). BECAUSE OF THE MOVEMENT OF THE CAR, WITHOUT A DRIVER AND IN THE WALL, THE SECURITY GUARD TRIED TO GET PEOPLE OUT OF THE BUILDING. THE TOWING COMPANY COULD NOT 'PULL' THE VEHICLE OUT OF THE WALL WITH THEIR TOW TRUCK FOR MORE THEN 20 MINUTES SO, I GAVE MY CAR KEY TO THE POLICE OFFICER AND HE GAVE IT TO THE TOWING COMPANY. THE MAN FROM THE TOWING COMPANY DROVE THE CAR OUT OF THE WALL AND OUT OF THE STUDIO.

BRAKES ON 2005 TOYOTA PRIUS STARTED INTERMITTENTLY ACTING UP ABOUT A YEAR AGO, AFTER SIX YEARS OF NO PROBLEMS. OBSERVED SYMPTOMS WERE EXTREME JERKINESS OF BRAKE OPERATION DESPITE CONSTANT PRESSURE ON BRAKE PEDAL. SYMPTOMS OBSERVED AT ANY SPEED, BUT ESPECIALLY NOTICEABLE AT SLOW SPEEDS (COMING TO A FINAL STOP, SUCH AS AT A TRAFFIC LIGHT, OR IN REVERSE BACKING OUT OF DRIVEWAY). WHEN APPLYING BRAKES AT HIGHWAY SPEEDS, JERKINESS FELT LIKE ALTERNATE OVER BRAKING / UNDER BRAKING. SYMPTOMS WERE QUITE SCARY THE FIRST TIMES IT HAPPENED. HAD PERSONAL MECHANIC CHECK OUT BRAKES. TEST DRIVE CONFIRMED PROBLEM, BUT HE WAS UNABLE TO FIND ANYTHING WRONG WITH HYDRAULIC BRAKE SYSTEM. SINCE PROBLEM WAS INTERMITTENT, WE DECIDED TO SEE WHAT HAPPENED. PROBLEM CONTINUED INTERMITTENTLY, GRADUALLY INCREASING IN FREQUENCY TO THE POINT IN THE LAST MONTH WHERE IT WAS HAPPENING MUCH MORE OFTEN THAN NOT. TOOK CAR TO TOYOTA DEALER FOR DIAGNOSIS. PROBLEM WAS NOT EVIDENT ON DAY OF SERVICE. THEY CHECKED COMPUTER FOR STORED ERROR CODES, AND FOUND NONE. REAR BRAKE DRUMS SHOWED SLIGHT WEAR AND WERE OUT OF ADJUSTMENT, SO DRUMS WERE CLEANED AND TURNED AND BRAKES ADJUSTED. NO DIFFERENCE IN OBSERVED BEHAVIOR; BY END OF THE NEXT DAY, JERKY BEHAVIOR NOTED AS BAD AS IT HAD EVER BEEN. TOOK CAR BACK TO DEALER. THEY REPLACED THE STROKE SENSOR EVEN THOUGH THERE WAS NO STORED ERROR CODE. THIS APPEARS TO HAVE FIXED THE PROBLEM, SINCE THERE HAS BEEN NO RECURRENCE OF PROBLEM IN A WEEK OR DRIVING SINCE REPAIR. BRAKES FEEL TOTALLY NORMAL AGAIN, FOR THE FIRST TIME IN A YEAR. NOTE ON DIAGNOSIS PROCEDURE: THE DEALER SEEMED TO INITIALLY DISCOUNT MY DETAILED, WRITTEN DESCRIPTION OF THE PROBLEM, AND REACTED ONLY TO THEIR OBSERVATIONS. WHILE UNDERSTANDABLE, IT IS FRUSTRATING TO THE OWNER AND COULD LEAD TO A SERIOUS PROBLEM NOT GETTING FIXED. I FEEL THAT THE SYMPTOMS AS DESCRIBED TO THEM POINTED DIRECTLY TO THE STROKE SENSOR AND IT SHOULD HAVE BEEN REPLACED ON THAT BASIS. *TT

TL* THE CONTACT OWNS A 2005 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS HE NOTICED THE ENGINE LIGHT, THE ABS, AND THE BRAKE LIGHT ILLUMINATED. THE VEHICLE THEN STARTED TO MAKE A LOUD CLUNKING NOISE AND THEN WHEN DECELERATING HE NOTICED THAT THE ABS STARTING TO KICK IN WHEN IT SHOULDN'T. THE VEHICLE WAS THEN TAKEN TO A DEALER AND THEY ADVISED HIM THAT THE COMPUTER HAD MALFUNCTIONED ON THE ABS SYSTEM AND THE RIGHT FRONT WHEEL HAD LOCKED UP. THE VEHICLE HAS NOT BEEN REPAIRED. THE MANUFACTURER WAS CONTACTED AND THEY ADVISED HIM THEY WILL ESCALATE THE FAILURE. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 110,000. THE VIN WAS UNAVAILABLE.

WERE DRIVING A 2005 TOYOTA PRIUS, WHEN THE BRAKES SUDDENLY STARTED BEHAVING ERRATICALLY, WOULD NOT DEPRESS WHEN PRESSURE WAS APPLIED. ALL ABS /VSC LIGHTS CAME ON, DROVE TO THE NEAREST DEALERSHIP (GLENDALE, CA TOYOTA). THEY SAID THAT THE BRAKES HAD SHORT CIRCUITED AND NEEDED TO BE REPLACED. ($2500 PART), SUBSEQUENTLY THEY SAID THAT THE SKID CONTROL ECU WAS ALSO GONE AND HAD TO BE FIXED. THIS WAS ANOTHER $1500 PART. ON READING OTHER COMPLAINTS, THIS SOUNDS LIKE A MAJOR AND COMMON ISSUE, DOES NOT APPEAR THAT TOYOTA IS ADDRESSING OR EVEN REVIEWING THE PROBLEM. THIS IS A SINGLE OWNER CAR, ALL MAINTENANCE SERVICE FOLLOWED AND WITH ONLY 62,000 MILES ON THE CAR. *TR

NOTE: THE DATE ABOVE DOES NOT REFLECT FIRST DATE OF OCCURANCE. THIS IS THE EVENT DATE THAT LED TO TOYOTA ADMITTING SOMETHING IS WRONG WITH THE CAR. PLEASE READ NARRATIVE: ON THREE OCCASIONS THE CAR HAS DIED WHILE BEING PARKED AT WORK AND AT HOME. ON ONE OCCASION THE CAR DIED IN MY GARAGE. AFTER THE VEHICLE WAS JUMPED IT SEEMED FINE. NO LIGHTS WERE LEFT ON NOR WERE ANY ELECTRICAL DEVICES PLUGGED INTO THE ACCESSORIES. WHEN IT STARTED UP THE CAR STATED THAT THE PARKING BRAKE WAS NOT PROPERLY ENGAGED AND THE VEHICLE NEEDED TO BE MOVED TO A LEVEL SURFACE. IT WAS IN MY DRIVEWAY. ANOTHER TIME THE CAR DID THE SAME THING, DYING AT WORK IN THE AIRPORT EMPLOYEE PARKING LOT. THE CAR REQUIRED BEING JUMP STARTED AND AGAIN IT GAVE THE SAME MESSAGE. A CO-WORKER STATED THAT THEY HAD HEARD THE CAR ALARM GO OFF AT ONE POINT ABOUT AN HOUR PRIOR TO SHIFT CHANGE. BOTH TIMES THE VEHICLE WAS CHECKED AND THE REPORT WAS NOTHING WAS WRONG WITH THE CAR. MOST RECENTLY ON 3/27/2011 THE SAME THING OCCURRED. THIS TIME WHEN JUMP STARTING THE BATTERY THE CARS ENGINE STARTED AND THE CAR LUNGED FORWARD AT ME WITH LIGHTS AND ALARM SOUNDING. I WAS UNABLE TO SHUT DOWN THE ALARM AND WENT INTO THE CAR AND PRESSED THE POWER BUTTON TO SHUT THE ENGINE DOWN. WHEN I POWERED THE ENGINE BACK UP THE CAR ALARM WAS AGAIN SOUNDING AND ALL THE LIGHTS ON THE DASH WERE ILLUMINATED. POWERED IT DOWN AND UP AGAIN AND THIS TIME NO AUDIBLE ALARM BUT THE EXCLAMATION MARK IN THE TRIANGLE WAS ILLUMINATED AS WELL AS THE MESSAGE ABOUT THE PARKING BRAKE. I POWERED IT DOWN AND UP ONE LAST TIME AND, WITH THE MESSAGE STILL ILLUMINATED, DROVE OFF. THE MESSAGE SHUT DOWN WHEN I GOT TO THE SECURITY GATE. TOYOTA TESTED THE VEHICLE ON 4/1/2011 AND REPORTED THAT C1300 AND C2300 FAULTS WERE FOUND (ECU AND ABS ACTUATOR). AS THE CAR IS OUT OF WARRANTY, COST WILL BE ABOUT $3,000.00. (MORE INFO EXISTS BUT NO ROOM HERE)

WE HAVE NOTICED REPEATEDLY (A DOZEN OR MORE TIMES) OVER THREE YEARS OF OWNING THIS CAR AND 100K MILES, THAT AS WE BRAKE GOING OVER A BUMPY SECTION OF ROAD, THE BRAKING SYSTEM FAILS AND THE CAR ACTUALLY ACCELERATES FOR ONE OR TWO SECONDS. THIS IS ESPECIALLY ALARMING WHEN WE NEED TO BRAKE SUDDENLY IN A CURVE ON A BUMPY ROAD AS IT SEEMS WE WILL LOSE CONTROL OF THE CAR. I ALWAYS BRAKE WITH MY RIGHT FOOT AND MY RIGHT FOOT REMAINS OFF THE ACCELERATOR AND ON THE BRAKE THROUGHOUT THESE EPISODES. OUR CAR IS EQUIPPED WITH THE VEHICLE STABILITY SYSTEM AND THE PASSENGER NOTICES THAT THE STABILITY SYSTEM WARNING LIGHT COMES ON DURING THESE EPISODES. IT IS NOT SIMPLY THAT THE CAR COASTS WHEN THE BRAKING FAILS, THE ENGINE ACTUALLY SOUNDS LIKE IT IS REVVING UP AND THE CAR NOTICEABLY SPEEDS UP. ONCE THE BUMPY SECTION HAS BEEN PASSED, NORMAL BRAKING RESUMES. THIS HAS NOTHING TO DO WITH THE FLOOR MAT. THIS SITUATION SHOULD BE REPRODUCIBLE THRU TESTING.

MY CAR, A 2005 TOYOTA PRIUS, WAS STATIONARY AT A STOPLIGHT ON A CLEAR, SUNNY DAY. MY FOOT WAS ON THE BRAKE AND THE BRAKE WAS FULLY DEPRESSED. I COULD FEEL A SUDDEN PRESSURE CHANGE IN THE BRAKE, AND WARNING LIGHTS CAME ON. I DROVE THE SHORT DISTANCE TO WORK, BUT THE CAR WAS HANDLING BADLY (WOBBLY) AND THE BRAKE WAS VERY SOFT AND ONLY PARTIALLY EFFECTIVE. AFTER WORK, A FEW HOURS LATER, THE CAR SEEMED TO BE HANDLING NORMALLY AND BRAKING NORMALLY, BUT I DROVE TO THE CLOSEST DEALER AS A PRECAUTION. THEY CHECKED THE COMPUTER AND FOUND CODE C1357 (DECREASING PRESSURE SOLENOID MALFUNCTION). THEY REPLACED THE BRAKE ACTUATOR ASSEMBLY. *TR

THE BRAKES ON MY 2005 PRIUS APPEAR NOT TO GRAB IMMEDIATELY WHEN I AM DRIVING OVER A ROUGH SURFACE. THIS HAS HAPPENED SINCE I HAVE OWNED THE CAR BUT ON AN IRREGULAR BASIS. SINCE IT OCCURRED GENERALLY WHEN I WAS MOVING VERY SLOWLY I DIDN'T VIEW IT AS A SAFETY PROBLEM BUT A COUPLE OF TIMES RECENTLY I HAVE BEEN DRIVING OVER A VERY ROUGH ROAD AT HIGHER SPEED AND THE SAME LACK OF BRAKING OCCURRED. IT IS AS IF THERE IS A PAUSE BEFORE THE BRAKING SYSTEM KICKS IN. *TR

2005 PRIUS: WHEN I BRAKE AS I DRIVE OVER ANY KIND OF VARIATION IN THE ROAD (WHICH IS QUITE OFTEN), MY VEHICLE LURCHES FORWARD AND I AM UNABLE TO COME TO A STOP RIGHT AWAY. I HAVE TO DEPRESS THE BRAKE QUITE HARD TO MAKE IT STOP AND IT IS VERY DANGEROUS. I HAVE TAKEN MY VEHICLE TO THE DEALERSHIP FOR THIS ISSUE TWICE AND THEY HAVE NOT BEEN ABLE TO DUPLICATE THE ISSUE. I HAVE ALSO CALLED TOYOTA AND OPENED A CASE WITH THEM WHICH THEY CLOSED WITHOUT INSPECTING MY VEHICLE. *TR

WHEN I GO OVER A BUMP OR HIT A POTHOLE IN MY 2005 PRIUS AND I AM BRAKING IT FEELS LIKE MY BRAKES DISENGAGE FOR JUST A SECOND AND THE CAR SEEMS TO GO FASTER. I HAVE NEVER FELT COMFORTABLE WITH THIS SITUATION BUT SINCE I DON'T KNOW A WHILE LOT ABOUT CARS I THOUGHT IT MIGHT BE NORMAL UNTIL I SAW AN ARTICLE IN THE NEWSPAPER FROM ANOTHER PRIUS OWNER WITH THE SAME COMPLAINT. THIS ARTICLE SUGGESTED A COMPLAINT BE FILED WITH NHTSA. I AM FILING THIS WITH THE DATE OF THE NEWSPAPER ARTICLE ALTHOUGH THE STRANGE BRAKING FEELING HAS BEEN ONGOING SINCE I PURCHASED THE VEHICLE IN JUNE 2005. *TR

I DRIVE A 2005 TOYOTA PRIUS. I AM CONCERNED WITH HOW THE BRAKES OPERATE. WHEN I APPLY THE BRAKES AND HIT A BUMP AT THE SAME TIME, THERE IS WHAT FEELS LIKE A LAG OR "RELEASE" IF YOU WILL IN THE BRAKING OF THE CAR. IT'S ONLY FOR ABOUT A SECOND BUT IS VERY FRIGHTENING. TO PUT IT ANOTHER WAY, WHEN TRYING TO BRAKE THE CAR AND HITTING A BUMP IN THE ROAD, THE BRAKES :"FAIL" MOMENTARILY AND THEN RE-ENGAGE. THIS HAPPENS FOR ABOUT 1/2 OF A SECOND ALTHOUGH IT FEELS LONGER. I HAVE READ OTHER COMPLAINTS ABOUT THIS ISSUE AND TOYOTA RESPONDED TO THESE COMPLAINTS SAYING THE "LAG" IS CAUSED BY THE ABS SYSTEM KICKING IN. I DON'T UNDERSTAND THE LAG TIME THOUGH, IT SEEMS EXCESSIVE TO ME NOT TO MENTION DANGEROUS. I BELIEVE THE NEWER PRIUS' HAVE BEEN RECALLED FOR A SIMILAR PROBLEM AND AM WONDERING IF THE 2005'S WILL BE AS WELL. *TR

I HAVE A 2005 TOYOTA PRIUS AND HAVE CONCERNS ABOUT ITS BRAKING SYSTEM. THIS HAS BEEN A CONSTANT OCCURRENCE THAT, TO DATE HAS NOT CAUSED A CRASH. WHEN BRAKING ON A BUMPY ROAD IT FEELS LIKE THE BRAKING SYSTEM DOES NOT ENGAGE FOR ABOUT A SECOND AND THE CAR SURGES FORWARD.

I HAVE MADE COMPLAINTS TO THE DEALERSHIP SINCE I PURCHASED MY 2005 TOYOTA PRIUS REGARDING A MOMENTARY BRAKE FAILURE WHEN DRIVING OVER A BUMP OR HITTING A POTHOLE. I HAVE BEEN TOLD EVERYTHING FROM "IT IS JUST HOW ABS WORKS" TO "YOU NEED TO HIT THE BRAKE HARDER WHEN YOU COME TO A STOP" (I.E. RATHER THAN A SLOW AND CAREFUL STOP, A QUICK AND SHARP STOP). THERE ARE TOO MANY INCIDENTS TO NAME BUT ONE THAT OCCURS ROUTINELY IS ABOUT 30 YARDS AWAY FROM A STOP SIGN LEADING INTO THE PARKING LOT AT MY PLACE EMPLOYMENT. I NOW HAVE TO COAST VERY CAREFULLY AND PREPARE MYSELF FOR BRAKE FAILURE. SHOULD THERE BE CARS AROUND, THIS BECOMES A DANGEROUS MATTER.

2005 TOYOTA PRIUS--EXPERIENCES BRAKING AND HANDLING FAILURES WHEN BRAKING ON UNEVEN OR WET SURFACES. WHEN WE ARE BRAKING AND HIT A POTHOLE, GRAVEL, RAILROAD TRACKS OR WET SURFACES, THE CAR FEELS AS IF WE ARE LOSING CONTROL OF IT, AND BRAKING SEEMS TO TEMPORARILY STOP. THE "SKID DANGER" LIGHT COMES ON, EVEN AT VERY LOW SPEEDS. THIS HAPPENS NEARLY EVERY TIME WE BRAKE UNDER THESE CONDITIONS. ALSO, AT IDLE (IE. STOPLIGHTS), THE CAR WILL FREQUENTLY LURCH FORWARD SLIGHTLY, EVEN WITH THE BRAKE PEDAL FULLY DEPRESSED, ESPECIALLY WHEN ENGINE TRANSFERS FROM ELECTRIC TO GAS. WE WERE TOLD EARLY IN OUR OWNERSHIP THAT THIS IS NORMAL "DIESELING". THESE HAVE BEEN ON-GOING PROBLEMS, SINCE WE PURCHASED THE CAR IN 2005 (NEW), THAT WE THOUGHT WE WERE "IMAGINING" UNTIL HEARING ALL OF THE REPORTS OF SIMILAR PROBLEMS.TOYOTA CLAIMS THAT THE PRIUS BRAKING ISSUES ONLY AFFECT THE 2010 PRIUS, BUT WE SEE IT FIRSTHAND ON AN ON-GOING BASIS. *TR

ABOUT 6 MONTHS AGO, I WAS ON I-95 IN FT. LAUDERDALE, JUST EXITING: I TOUCHED THE BRAKES TO SLOW -- AND THEY FIRMLY LOCKED. I TOUCHED THEM AGAIN AND, FORTUNATELY THEY WORKED NORMALLY. HAD THIS HAPPENED WHILE I WAS STILL ON I-95, THERE WOULD HAVE BEEN A HORRIBLE ACCIDENT. I REPORTED THIS TO TOYOTA, AT THEIR NYC HEADQUARTERS, WHEN THEIR OTHER PROBLEMS BECAME PUBLIC.

I HAVE BEEN ROUTINELY BRINGING MY 2005 PRIUS TO A TOYOTA DEALERSHIP EVERY 5K MILES ACCORDING TO MANUFACTURERS SUGGESTED MAINTENANCE SCHEDULE AND NEVER HAD A PROBLEM REPORTED TO ME. (ONE TIME THE SOFTWARE NEEDED TO BE RELOADED.) ON THE EVENING OF THE INCIDENT THAT I AM REPORTING, I HAD TRAVELED ON THE MASS TURNPIKE AND RTE 495 (~38 MI) HOME FROM WORK (~9:30 PM) AND SUCCESSFULLY SLOWED AND STOPPED MY 2005 TOYOTA PRIUS AS NEEDED. AS I GOT INTO ON LOCAL ROADS, I SUDDENLY LOST MY BRAKING ABILITY. FORTUNATELY I WAS GOING SLOWLY AND WAS ABLE TO ROLL TO A STOP. THERE WAS A REALLY SHRILL ALARM AND A RED LIGHT SHOWING ABS (ANTILOCK BRAKE PROBLEM)--I'LL SAY. I TESTED TO SEE IF THERE WAS ANY BRAKING POWER SO THAT I COULD GET THE CAR HOME. IF YOU PRESSED THE BRAKE TO THE FLOOR--THERE WAS SOME RESIDUAL SLOWING--SO I CREPT HOME. AAA TOWED MY CAR TO TOYOTA THE NEXT DAY AND TOYOTA ULTIMATELY IDENTIFIED THE PROBLEM AS A COMPUTER PROBLEM. THEY REPLACED THE 1 89540-47130 COMPUTER ASSEMBLY, SKID. ASIDE FROM THE COST ($2250), ITS THE POSSIBILITY THAT I COULD HAVE LOST MY BRAKES ON EITHER OF THE TWO HIGHWAYS THAT I TAKE ON THE WAY HOME, EXIT RAMPS, TOLL BOOTHS, AND THAT I OR SOME OTHERS COULD HAVE BEEN SERIOUSLY HURT, REALLY UPSETS ME. AND HOW DO I KNOW THAT THIS WILL NOT FAIL AGAIN? REGULAR SERVICE DOES NOT CHECK COMPUTER STATUS. I THINK THAT YOU SHOULD LOOK INTO COMPUTER PROBLEMS WITH TOYOTA AND ALSO WHAT TOYOTA INCLUDES IN REGULAR SERVICE. THEY SAY THAT THEY HAVEN'T SEEN THIS BEFORE, AND THAT MAY BE TRUE: I HAVE A 5 YR OLD PRIUS WITH MORE THAN 110K MILES ON IT AND I'LL BET THAT IS A LOT OF MILEAGE FOR A PRIUS. AS MORE PEOPLE DRIVE PRIUS'S FOR LONGER TIMES AND ACCRUE HIGHER MILEAGE, I WOULD BET THAT TOYOTA WILL SEE A LOT MORE OF THESE INCIDENTS. I THINK THAT YOU SHOULD BE PROACTIVE AND DEAL WITH THIS BEFORE PEOPLE GET HURT. *TR

I HAVE REVIEWED MY SERVICE RECORDS AND IT IS QUITE CLEAR THAT I HAVE HAD PROBLEMS WITH THE "ELECTRICAL" SYSTEM IN MY CAR SINCE APRIL 2006 @ 3,370 MILES. THIS WAS ALSO THE SAME TIME IT BEGAN TO ACCELERATE FROM A STOPPED POSITION FOR THE FIRST TIME, WHEN I NOTICED THAT THE BRAKING SYSTEM BEGAN TO "FEEL" DIFFERENT, WHEN THE CAR BEGAN "SLIPPING" ON PERFECTLY DRY ROADS, AND WHEN MY STEERING WHEEL WOULD LOCK UP. I FIND IT DIFFICULT TO BELIEVE THAT THE FAILURE OF MY BRAKES AND MY INTERMITTENT ACCELERATION ISSUES ARE NOT SOMEHOW RELATED TO THE CARS "COMPUTER" SYSTEM AND NOT MECHANICAL ISSUES. I HAVE FILED COMPLAINTS WITH TOYOTA FOR THESE ISSUES (CASES # 200807100210, 200811030088). I EXPERIENCED MY FIRST BRAKING ISSUE ON 27-JUN-2008 (25,133 MILES). WHILE I WAS ABLE TO BRING THE CAR TO A STOP EVENTUALLY, THE SLOWING OF MY CAR WAS A VERY GRADUAL PROCESS REQUIRING HEAVY PRESSURE ON THE BRAKE WITH MINIMAL BRAKING RESPONSE. I WENT TO THE TOYOTA DEALERSHIP. THE DTC CODE AT THE TIME WAS C1247 WITH "CODE 179" STORED, THERE WAS "NO BRAKE ASSIST." THE DEALERSHIP RESET THE MEMORY AND REINITIALIZED THE LINEAR SOLENOID VALVE AND CALIBRATION. THE BRAKES WERE REPORTED TO HAVE RETURNED TO "NORMAL." ON 09-JUL-2008 (25,551 MILES), I RETURNED TO THE DEALERSHIP BECAUSE MY BRAKES FAILED AGAIN. THIS TIME MY BRAKE FAILURE RESULTED IN A CAR ACCIDENT (THE PERSON I HIT STATED AT THE TIME OF THE ACCIDENT HE HAD WHIPLASH BUT HE NEVER CONTACTED ME AFTERWARDS). TOYOTA REPLACED THE SKID CONTROL ECU AND RECHECKED OPERATION REASSURING ME ONCE AGAIN THAT THE BRAKES HAD RETURNED TO "NORMAL." ON 03-NOV-2008 (29,575 MILES) AS I WAS DRIVING OVER 65 ON A MAJOR HIGHWAY MY BRAKES AGAIN FAILED (DTC C1247, CODE 179). TOYOTA CASE #08300402. AT THIS POINT THE REPAIR SHOP REPLACED THE BRAKE STROKE SENSOR. I AM CONCERNED BECAUSE MY CAR HAD AN ACCELERATION ISSUE ON 13-FEB-2010 AND I FIND IT TO BE "SLIPPING" AGAIN ON DRY ROADS. SIMILAR PROBLEMS TO THOSE I HAD BEFORE MY BRAKES FAILED. PLEASE HELP. UPDATED IVOQ 04/02/10 UPDATED 04/08/10.*JB

I WAS TRAVELING DOWN A RESIDENTIAL STREET AND APPROACHING A PEDESTRIAN INTERSECTION WHEN A PEDESTRIAN ON HER MORNING EXERCISE RUN SUDDENLY RAN ACROSS MY PATH. I IMMEDIATELY TRIED TO STOP, BUT THE EDGE OF THE SOLE OF MY DRESS SHOES WERE CAUGHT BEHIND THE BRAKE PEDAL, AND I WAS UNABLE TO MOVE MY FOOT ONTO THE PEDAL TO DEPRESS IT. ONLY BY STEERING AWAY FROM THE PEDESTRIAN, AND HER ACTION TO STOP, DID I AVOID A SERIOUS ACCIDENT. THE CAUSE OF THIS INCIDENT IS THE FACT THAT THE ACCELERATOR AND BRAKE PEDALS ARE DISPLACED BY SEVERAL INCHES, THAT IS, THE BRAKE PEDAL IS CLOSER TO THE DRIVER THAN WHAT THE ACCELERATOR IS. THIS REQUIRES ONE TO LIFT YOUR FOOT BY 6 INCHES OR SO BEFORE MOVING IT OVER TO THE BRAKE PEDAL TO DEPRESS IT. IN AN EMERGENCY SITUATION YOUR REFLEXIVE REACTION IS TO TRY TO MOVE YOUR FOOT OVER AS QUICKLY AS POSSIBLE. HOWEVER, THE DISPLACEMENT OF THE BRAKE PEDAL CREATES AN OBSTACLE THAN, IN THE BEST CASE, RESULTS IN A DELAY, AND IN THE WORST CASE RESULTS IN AN INABILITY TO OPERATE THE BRAKE PEDAL IN TIME TO AVOID AN ACCIDENT. *TR

I WOULD LIKE TO FILE AN OFFICIAL REPORT OF MY ACCIDENT THAT INVOLVED MY 2005 TOYOTA PRIUS ON JANUARY 13 OF THIS YEAR. IT WAS IN THE MORNING AFTER I HAD DROPPED OFF MY CHILDREN TO THEIR SCHOOL. I WAS DRIVING DOWN THE HILL AND DRIVING THE NORMAL 25- 30MPH DOWN THE HILL TO GO HOME. UPON COMING TO THE STOPLIGHT, I NOTICED THE CARS IN FRONT OF ME STOPPED AT THE STOPLIGHT SO I WENT TO HIT MY BRAKES AND DID NOT FEEL ANY POWER FROM MY BRAKES SO I QUICKLY STOOD ON MY BRAKES WITH BOTH FEET AND REALIZED I HAD ABSOLUTELY NO BRAKE POWER. I SUBSEQUENTLY CRASHED QUITE HARD INTO THE CAR IN FRONT OF ME AND EXPERIENCED SEVERE PAIN TO THE RIGHT SIDE OF MY NECK. AFTER INITIAL SHOCK, I WAS ABLE TO MANEUVER MY CAR OUT OF TRAFFIC TO A PARKING LOT AND NOTICED IT FUNNY THAT MY BRAKES WERE WORKING AT THAT POINT. AFTER EXCHANGING INFORMATION WITH THE MAN THAT I HIT, MY CAR WAS TOWED TO AN AUTOBODY SHOP. AFTER GOING TO KAISER TO LOOK INTO MY INJURY (WHICH WAS WHIPLASH) I WAS TOLD AT THE AUTOBODY SHOP THAT MY CAR WAS TOTALED AND COULD NOT BE FIXED. HE ALSO TOLD ME THAT MY AIRBAG DID NOT DEPLOY BECAUSE I HAD HIT A LARGER AMERICAN CAR WHICH WAS HIGHER THAN MY BUMPER. IT NEVER HIT THE AIRBAG SENSOR ON MY CAR THAT WAS LOWER THAN THE IMPACT POINT. AFTER THE ACCIDENT, I ASKED MY INSURANCE COMPANY, THE INTERINSURANCE EXCHANGE OF THE AUTOMOBILE , TO PLEASE LOOK INTO THE BRAKE SITUATION AND THEY STATED THAT THEY DID NOT FIND ANYTHING WRONG. I AM NOT SATISFIED WITH THIS ANSWER BECAUSE I HAVE READ THAT THE TOYOTA PROBLEMS ARE NOT EASY TO DIAGNOSE. I HAVE BEEN DRIVING FOR 27 YEARS AND HAVE NEVER BEEN IN AN AUTO CRASH THAT WAS MY FAULT. I ALSO HAVE NEVER EXPERIENCED SUCH A SCARY FEELING AS HAVING ABSOLUTELY NO CONTROL OVER MY CAR. *TR

ON 11/5/09 IN MID-AFTERNOON I WAS DRIVING MY 2005 PRIUS NORTH ON CALVERT ST. IN BALTIMORE CITY, JUST ABOVE SARATOGA ST., AT ABOUT 25 MPH WHEN THE TRAFFIC IN FRONT OF ME SLOWED. AT THE TIME I WAS SPEAKING TO MY BOSS ON MY VERIZON CELL PHONE USING MY BLUETOOTH HEADSET. I APPLIED MY BRAKES AND THE CAR WAS BRAKING AS USUAL SLOWING DOWN NORMALLY UNTIL ABOUT 10 MPH, OR SO, AT WHICH POINT I FELT THE CAR BOUNCE VERY SLIGHTLY AND GENTLY AS IF THERE WAS A SMALL GRADUAL DIP AND RISE IN THE ROADWAY SURFACE. MY FOOT WAS STILL APPLYING LIGHT PRESSURE ON THE BRAKE PEDAL AS I INTENDED TO COME TO A NEAR CRAWL AS I NEARED THE CAR IN FRONT OF ME, BUT AFTER THE SLIGHT BUMP THE BRAKE PEDAL GRADUALLY WENT TO THE FLOOR AND MY CAR PROCEEDED WITHOUT ANY BRAKING IN EFFECT. AFTER THE PEDAL WAS DEPRESSED TO A POINT NEAR THE FLOOR I PUMPED THE BRAKE PEDAL ONCE AND PRESS ON IT AS HARD AS POSSIBLE. AT THIS POINT THE RIGHT REAR WHEEL BRAKE APPLIED AND THE RR TIRE SQUEALED AS IT APPEARS IT WAS THE ONLY ONE BRAKING. I CONTINUED PRESSING UNTIL THE CAR CAME TO A STOP AT WHICH POINT I NOTICE THAT SEVERAL OF THE INSTRUMENT PANEL LIGHTS WERE NOW ON, INCLUDING THE ONES FOR THE BRAKE, THE ABS, AND VSC. I THEN CONTINUED DRIVING SLOWLY HOME, ABOUT 2 MI., BECAUSE IT APPEARED THAT ONLY THE RR BRAKE WAS WORKING AND THAT THERE WAS NOT POWER ASSIST WITH THE BRAKING. WHEN I GOT HOME I TURNED THE CAR OFF AND THEN BACK ON TO SEE IF THE PROBLEM PERSISTED, AND UPON RESTART THE BRAKES APPEARED TO WORK PROPERLY AND SOME OR PERHAPS ALL OF THE WARNING LIGHTS WERE OFF. I TOOK THE CAR TO BILL KIDD TOYOTA IN TIMONIUM, MD ON 11/9/09 AND THEY REPORTED THAT SCAN CODE C1357 WAS PRESENT. THEY REPORTEDLY CONTACTED TOYOTA TECH ASSISTANCE WHO INSTRUCTED THEM TO CLEAR THE SCAN CODES AND PERFORM LINEAR SOLENOID CALIBRATION. THEY ROAD TESTED THE CAR AND SAID IT WAS OK TO DRIVE. MY BOSS WAS ON THE PHONE WITH ME DURING THE ENTIRE INCIDENT AND HEAR THE RR TIRE SQUEALING AND WE DISCUSS WHAT WAS GOING ON. I AM A MECHANICAL ENGINEER. *TR

PLEASE NOTE THIS IS MY SECOND COMPLAINT ABOUT MY PRIUS'S BRAKES, BUT IT IS NOT A DUPLICATE COMPLAINT. MY CAR HAS TWO PROBLEMS WITH IT'S BRAKES WHICH SEEM TO ME TO BE UNRELATED. MY PRIUS BRAKES VERY ODDLY WHEN DRIVING IN THE RAIN, OR IN THE EARLY MORNING WHEN THERE IS APPRECIABLE DEW/CONDENSATION. WHEN GENTLY DEPRESSING THE BRAKE PEDAL AT A CONSTANT PRESSURE, THE CAR DECELERATES SLOWLY, THEN ABRUPTLY TRANSITIONS TO VERY RAPID DECELERATION, AS THOUGH I HAD SLAMMED THE BRAKE PEDAL DOWN HARD. IT IS VERY DIFFICULT TO MODULATE THE BRAKING. THIS HAPPENS SEVERAL TIMES, THEN SEEMS TO EASE UP AS THE VEHICLE IS OPERATED FOR AROUND 15 MINUTES. ON SEVERAL OCCASIONS I HAVE REPORTED THIS TO THE TOYOTA DEALERSHIP. THEY HAVE SOMETIMES DISMISSED THE COMPLAINT OUT OF HAND, AND ONCE ATTEMPTED IN VAIN TO REPLICATE THE DEFECT, UNSUCCESSFULLY. IN ANY EVENT, I HAVE ALWAYS BEEN TOLD MY BRAKES WERE OPERATING NORMALLY. PLEASE NOTE THAT THIS IS NOT THE SAME PROBLEM AS THE BRAKE FAILURE WHICH OCCURS WHEN BRAKING WHILE RIDING OVER A ROUGH OR UNEVEN SURFACE, WHICH MY VEHICLE ALSO DOES. AT LEAST, I ASSUME THE TWO PROBLEMS ARE UNRELATED. I HAVE FILED A SEPARATE COMPLAINT FORM FOR THAT PROBLEM. *TR

WE ORDERED A 2005 PRIUS IN THE FALL OF 2004 AND RECEIVED DELIVERY IN MAY 2005. MY WIFE DRIVES THE CAR MORE OFTEN THAN I DO AND SHE INFORMED ME THAT DURING TIMES OF WET OR RAINY CONDITIONS THE BRAKES "GRAB' WHEN APPLIED. THIS BRAKING PROBLEM WAS NOT APPARENT DURING THE FIRST YEAR. I'VE EXPERIENCE THE BRAKE "GRAB" EVERTIME I DRIVE IT IN WET WEATHER, AND EVEN THOUGH I TRY TO AVOID IT BY GENTLY APPLYING THE BRAKES, THEY THEY STILL "GRAB" THIS IS JUST NOT A "ONE TIME" OCCURENCE...I HAVE READ THE REPORTS FROM OTHER PRIUS OWNERS ABOUT THE BRAKES.

MY 2005 TOYOTA PRIUS HAS THE SAME BRAKE/ACCELERATION PROBLEM THAT HAS BEEN REPORTED IN THE MEDIA. SOMETIMES WHEN I APPLY THE BRAKES ON BUMPY SURFACES, THE CAR TENDS TO ACCELERATE - OR EVEN LIFT UP SLIGHTLY - UNTIL THE WHEELS TOUCH DOWN AND REGAIN CONTACT WITH A FLAT SURFACE. I NEVER PUMP THE BRAKES, BUT WHEN THIS HAPPENS, MY CONTROL OVER THE VEHICLE IS MOMENTARILY INTERRUPTED. THIS PROBLEM HAS RECURRED ON NUMEROUS OCCASIONS SINCE I BOUGHT THE CAR A FEW YEARS AGO, BUT I IGNORED IT. HOWEVER, WHEN I READ A DESCRIPTION OF THIS BRAKING PROBLEM BEING REPORTED ON 2010 MODELS, I IMMEDIATELY RECOGNIZED IT AS SOMETHING THAT I HAVE EXPERIENCED FROM TIME TO TIME.

AFTER LISTENING TO PUBLICITY ABOUT THE 2010 PRIUS PROBLEM I REALIZE THAT I HAVE HAD THE SAME PROBLEM OF BRAKE FADE IN MY 2005 PRIUS. THERE IS A BRIDGE SECTION THAT I DRIVE OVER SEVERAL TIMES A MONTH. THIS BRIDGE SECTION IS 1 INCH HIGHER THAN THE ASPHALT ROAD AND ON A STEEP HILL IMMEDIATELY BEFORE A STOP SIGN. SO IF I AM BRAKING AS I HIT THE BRIDGE SECTION, I NOTICE AN IMMEDIATE BRAKE FADE. SO FOR ALL THESE YEARS, I ASSUMED IT WAS AN ABS PECULIARITY WITH CAR UNWEIGHTING. I'VE LEARNED TO BRAKE HARD IMMEDIATELY BEFORE I ENTER THE BRIDGE SECTION, RELEASE THE BRAKES AS I HIT THE EDGE OF THE BRIDGE SECTION, BRAKE HARD ON THE BRIDGE SECTION AND RELEASE AS I DROP OFF THE SECTION, THEN BRAKE TO THE STOP SIGN. I HAVE NEVER EXPERIENCE THIS PROBLEM IN OTHER SITUATIONS BUT I AM AWARE OF THE BRAKE FADE AND MIGHT BE ANTICIPATING THE PROBLEM. IT HAS BEEN OCCURRING SINCE I PURCHASED THE CAR IN 2005. *TR

MY WIFE AND I RECENTLY BOUGHT A USED 2005 PRIUS FROM WILDE TOYOTA IN WEST ALLIS, WI. IN THE LAST FEW MONTHS WE HAVE EXPERIENCED BRAKING ISSUES WITH THE VEHICLE ON ICY ROADS, SLICK ROADS, AND SNOW COVERED ROADS. WE HAVE HAD THREE BRAKE FAILURES. THE FIRST WAS WHEN I WAS DRIVING ON A SIDE-STREET. I WAS GOING SLOW, LESS THEN 15 MILES PER HOUR, AND STEPPED ON THE BRAKES TO MAKE A TURN. THE BRAKES WERE UNRESPONSIVE FOR APROX. 2 SECONDS CAUSING ME TO ROLL BEFORE THE BRAKES ENGAGE. THE SECOND OCCURED WHEN MY WIFE WAS DRIVING AT A LOW SPEED, UNDER 40 MILES AN HOUR, ON A MAIN ROAD. AS SHE APPROACHED THE STOPLIGHT SHE STEPPED ON THE BRAKES, WHICH ALSO FAILED TO ENGAGE. DUE TO HER HIGHER SPEED SHE ROLLED OVER 10 FEET AND CAME CLOSE TO HITTING THE CAR STOPPED IN FRONT OF HER BEFORE THE BRAKES FINALLY ENGAGED. THE FINAL OCCURANCE ALSO OCCURED WHEN MY WIFE WAS DRIVING, THIS TIME AT A HIGHER SPEED BETWEEN 40 AND 50 MILES PER HOUR, WHEN PRESSING ON THE BRAKES ON AN OVERPASS THE BRAKES FAILED TO ENGAGE AND THE CAR PHYSICALLY SEEMED TO SHAKE A BIT. AFTER BEING UNABLE TO STOP FOR SEVERAL FEET THE BRAKES FINALLY ENGAGED. WE BELIEVE THESE OCCURANCES ARE DUE TO AN ERROR WITH OUR ABS SYSTEM. IN EACH OCCURANCE THE "SLIPPERY ROAD" WARNING HAS APPEARED. WE TOOK IT TO WILDE TAYOTA THIS MORNING. AFTER SOFTWARE TESTING AS WELL AS ROAD TESTING ON THEIR SNOW COVERED LOT THEY FAILED TO REPLICATE THE PROBLEM. NO SYSTEM ERRORS WERE PRESENT AND THEY WERE UNABLE TO TAKE ANY FURTHER ACTION. WE ARE, HOWEVER, STILL CONVINCED THAT A PROBLEM EXISTS. IF IT OCCURS AGAIN WE WILL ONCE AGAIN TAKE IT TO THE DEALERSHIP AND TRY TO REPLICATE THE PROBLEM. *TR

ABS SYSTEM FAILURE WHILE PREPARING TO STOP FROM 40 MPH IN 05 TOYOTA PRIUS LAST SEPTEMBER.

I OWN A 2005 PRIUS, BOUGHT NEW. I NOW HAVE 130,000 MILES ON IT. IT HAS BEEN SERVICED AND MAINTAINED AT SCHEDULED INTERVALS, MOSTLY BY A TOYOTA DEALER. #1: I HAVE COMPLAINED TO THE DEALER SINCE THE FIRST WINTER THAT I BOUGHT THE CAR THAT THE "TRACTION CONTROL SYSTEM" IS DANGEROUS IN BAD WEATHER CONDITIONS. WHENEVER THE ROAD IS SLIPPERY, IF THE CAR SENSES WHEELSPIN, IT CUTS POWER TO THE ENGINE. THIS IS SCARY IF YOU'RE PULLING OUT INTO TRAFFIC ON A RAINY DAY, AS THE CAR WILL SOMETIMES JUST QUIT RUNNING FOR A SECOND, LEAVING YOU VULNERABLE TO ONCOMING TRAFFIC. SNOW IS FAR WORSE. I LIVE ON A HILLY ROAD. IF IT'S SNOWY THE CAR WILL SLOW DOWN, AND SIMPLY STOP TRYING TO MOVE FORWARD ON THE FIRST STEEP SLOPE I COME TO. IT DOESN'T MATTER HOW HARD I MASH ON THE ACCELERATOR, OR IF I BACK OFF AND TRY AGAIN, THE CAR WILL NOT ATTEMPT TO MOVE. ONCE THE CAR STOPS MOVING FORWARD IT BEGINS TO SLIDE BACKWARDS, AND CONTROL IS TOTALLY LOST. I WAS NEARLY KILLED THE FIRST TIME THIS HAPPENED (IN ABOUT ONE INCH OF SNOW) AS MY CAR EVENTUALLY SLIPPED SIDEWAYS ACROSS THE ONCOMING TRAFFIC LANE. AN SUV CAME DOWN THE HILL AND NEARLY BROADSIDED ME BEFORE I WAS ABLE TO GET MY CAR TURNED BACK DOWN THE HILL. (MY CAR WAS EQUIPPED WITH AGGRESSIVE SNOW TIRES AT THE TIME.) EVER SINCE THEN, IF I'M COMING HOME FROM WORK IN THE SNOW, I LEAVE MY CAR IN THE SHOPPING CENTER AT THE BOTTOM OF THE HILL AND CALL MY HUSBAND, WHO PICKS ME UP WITH HIS FORD BRONCO. # 2: ANTI-LOCK BRAKING. THE 2010 PRIUS'S AREN'T THE ONLY ONES WITH PROBLEMS; MINE DOES THE SAME THING. IF I'M BRAKING ON A BUMPY STRETCH OF ROAD OR OVER A MANHOLE COVER IN THE RAIN, THE CAR WILL CUT POWER TO THE BRAKES, CAUSING THE CAR TO FEEL LIKE IT'S SURGING FORWARD. AGAIN THIS PROBLEM IS MUCH WORSE IN THE SNOW. GOING DOWNHILL ON A SNOWY, SLIPPERY HILL THE ANTI-LOCK BRAKES REPEATEDLY CUT BRAKING POWER, WHICH ACTUALLY CAUSES THE CAR TO ACCELERATE TO UNSAFE SPEEDS. MY DEALER TELLS ME THAT THIS IS HOW THE CAR WORKS, AND NOTHING CAN BE DOME TO CORRECT IT. *TR

Mileage: 1,000

I HAVE BEEN COMPLAINING TO THE DEALER SINCE I HAVE HAD MY 2005 PRIUS (I BOUGHT IT NEW) THAT AT SLOW SPEEDS ON OCCASION WHEN I JUST VERY LIGHTLY TOUCH THE BRAKE MY PRIUS WILL SUDDENLY STOP AS IF I HAD SLAMMED ON THE BRAKES. THEY INSIST THAT THEY HAVE TO SEE THE PROBLEM BEFORE THEY CAN DO ANYTHING ABOUT IT. NATURALLY THE CAR DOESN'T DO IT WHEN THEY HAVE IT FOR SERVICE. I SELECTED "SERVICE BRAKES HYDRAULIC" BELOW BECAUSE, YOU DON'T HAVE A SELECTION FOR JUST "BRAKES". *TR

2005 TOYOTA PRIUS - I HAVE HAD BRAKING PROBLEM. NEAR WHERE I LIVE THERE IS A SMALL POTHOLE NEAR AN INTERSECTION WITH A STOP SIGH. WHEN TRYING TO STOP IF I HIT THE POTHOLE THE CAR'S BRAKES JUST SEEM TO DISAPPEAR FOR A SECOND. ALMOST RAN OUT THROUGH STOP SIGN. THIS HAS HAPPENED A COUPLE OF TIMES SO I AM NOW VERY CAREFUL TO AVOID THE HOLE BY NEARLY RUNNING OFF THE RIGHT SIDE OF THE ROAD. NOW I HEAR THERE IS A RECALL FOR THE SAME THING WITH THE 2010 PRIUS. I'VE ALREADY HAD THE "FLOOR MAT" RECALL. THIS CONCERNS ME BECAUSE I WONDER IF IT IS REALLY THE FLOOR MATS OR THE RUN AWAY GAS PEDAL PROBLEM. I'M GOING ON VACATION AND SERIOUSLY CONSIDERING RENTING A CAR BECAUSE I'M ALMOST AFRAID TO DRIVE MY CAR. *TR

I HAVE BECOME ACCUSTOMED TO THE ODD FEELING AND THE SITUATION IS ALWAYS ONLY MOMENTARY SO I CAME TO THINK NOTHING OF IT.

THE BRAKES "SLIP" WHEN DRIVING OVER A BUMP OR POTHOLE IN THE ROAD. THIS EXPERIENCE IS SIMILAR TO WHAT HAS BEEN DESCRIBED IN THE 2010 PRIUS MODEL RECALL. I AM DRIVING A 2005 PRIUS HYBRID AND HAVE EXPERIENCED SIMILAR SLIPS SINCE I PURCHASED THE VEHICLE IN OCTOBER OF 2005. TO DATE THE SLIPPING HAS NOT RESULTED IN A CRASH, INJURY OR FAILURE HOWEVER I HAVE HAD SOME CLOSE CALLS. *TR

SEVERAL TIMES OVER PAST 5 YEARS MY 2005 TOYOTA PRIUS ABS SYSTEM HAD RELEASED THE BRAKES FOR UNCOMFORTABLE AMOUNT OF TIME (0.5-1.0 SECONDS) WHEN COMING TO A STOP OVER SLIGHTLY BUMPY ROAD. IF I DIDN'T KEEP GOOD DISTANCE I COULD HAVE CRASHED INTO A VEHICLE IN FRONT OF ME. *TR

2005 TOYOTA PRIUS HAS BRAKE ISSUE. WHEN BRAKING OVER POTHOLE OR BUMP, I MOMENTARILY LOOSE ALL BRAKE. THE BRAKE COMES BACK ABOUT 1 SEC LATER. THIS HAS ALWAYS HAPPENED, I HAVE TALKED TO THE DEALER SEVERAL TIMES, BUT I AM ONLY TOLD THAT I NEED TO 'GET USED TO IT'. *TR

I AM WRITING TO EXPRESS MY CONCERN OVER A ONE CAR ACCIDENT IN WHICH I WAS THE DRIVER. THIS ACCIDENT OCCURED ON A SNOW COVERED ROAD WHILE ON MY WAY TO WORK. I WAS DRIVING A 2005 TOYOTA PRIUS. THIS IS THE SAME EXPLANATION I GAVE TO THE POLICE AND TO THE INSURANCE COMPANY. I WAS DRIVING SOMEWHERE AROUND 40MPH WHEN I APPLIED THE BREAK. WHEN I DID THIS I DID NOT STAMP ON IT HARSHLY RATHER IN A NORMAL BREAK APPLICATION. IMMEDIATELY MY CAR SLAMMED ACROSS THE ROAD VERY VERY FAST, AND IT ROLLED OVER ON ITS SIDE. MY SEATBELT HELD ME FIRMLY IN PLACE BUT I WAS TILTED WITH MY HEAD DOWN BY THE PASSANGER SEAT AND MY LEGS UPWARDS TO TOWARD THE TOP OF THE STEERING WHEEL. I REMAINED IN THAT POSITION FOR ABOUT 20 OR 25 MIN.UNABLE TO MOVE UNTIL THE EMERGENCY SQUAD ARRIVED. I WAS TRANSPORTED TO THE HOSPITAL IN THE AMBULANCE. MY CAR WAS DECLARED TO BE TOTALLED. MY CONCERN IS THAT THE INSURANCE COMPANY KEEPS SAYING THAT THE CAR IS NOT ON A RECALL LIST BUT MY ACCIIDENT EXPERIENCE IS CURIOUSLY SIMILAR TO WHAT THEY ARE SAYING IS THE PROBLEM WITH THE 2010 TOYOTA HYBRIDS.. I THINK THEY SHOULD BE INVESTIGATING ALL POSSIBLE VEHICLE ISSUES. HOW CAN I PERSUE THIS? DO YOU HAVE ANY RECOMMENDATIONS? *CN

BRAKES STOP WORKING INTERMITTENTLY WHEN APPLIED GOING OVER ROUGH SURFACES SUCH AS RAILROAD TRACKS AND POTHOLES. THIS RESULTS IN A BRIEF SUSPENSION OF BRAKING ACTIVITY. OCCURS EACH TIME THE ABOVE CONDITIONS ARE MET AND BRAKES ARE APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE NEW. SINCE I ALWAYS REDUCE SPEED IN THESE POTENTIAL SITUATIONS, NO ACCIDENTS HAVE OCCURRED, BUT IT DOES RESULT IN AN INTERMITTENT LOSS OF BRAKING WHICH COULD RESULT IN REAR END COLLISIONS. PREVIOUSLY MY 1999 CHEVROLET SUV DID THE SAME THING AND I WAS TOLD IT WAS AN INHERENT CHARACTERISTIC OF THE ANTILOCK BREAKING SYSTEM. *CN

WHEN APPROACHING A LIGHT, I CHANGED LANES INTO THE LEFT TURN LANE, APPLIED THE BRAKE TO SLOW DOWN, LET UP ON THE BRAKE TO GO OVER A DEPRESSED AREA WHERE A PIPE WAS BEING REPLACED AND THE ROAD REPAIRED. I THEN APPLIED THE BRAKES FIRMLY TO STOP THE VEHICLE. UNFORTUNATELY, NOTHING HAPPENED. THE TRACTION CONTROL LIGHT WENT ON WHEN I WENT OVER THE BUMP AND IT TOOK ABOUT 2 SECONDS OF HEADING TOWARDS THE BACK OF A TRUCK FOR THE BREAKS TO ENGAGE AT ALL. WHEN THEY FINALLY ENGAGED, THE CAR STOPPED VERY QUICKLY (AS I WOULD EXPECT) AND I WAS ALMOST REAR ENDED BY THE PERSON BEHIND ME. I HAVE HAD THE BRAKES NOT ENGAGE ON ONE OTHER INCIDENT THAT ALSO INVOLVED SWITCHING LANES AND A BUMP. TRACTION CONTROL AND ABS ON THIS PRIUS NEED TO BE REPLACED WITH SOMETHING THAT WILL NOT KILL. I WAS VERY DISAPPOINTED THAT THE "BRAKING PROBLEM" WAS "LIMITED" TO 2010 PRIUSES. IT IS NOT. THIS ISSUE HAS CLEARLY OCCURRED TWICE FOR ME IN THE PAST 5 YEARS OF MODERATE DRIVING (ABOUT 10K MILES PER YEAR). TO ADDRESS THE ISSUE, TOYOTA TOLD ME THAT I WAS MAKING IT UP, IT NEVER HAPPENED, I MUST HAVE NOT PRESSED THE BRAKE PEDAL. I NEVER RELEASED MY FOOT FROM THE PEDAL AND THE CAR STOPPED JUST FINE AFTER A SIGNIFICANT DELAY. THEY DID NOT REPLACE ANY PARTS OR MAKE ANY CHANGES TO THE VEHICLE. *TR

Mileage: 30,000

WE HAVE A 2005 TOYOTA PRIUS THAT WAS INVOLVED IN AN ACCIDENT AS A RESULT OF THE CAR TAKING OFF ON IT'S OWN AND THE BRAKES NOT WORKING. THE PRIUS ONLY STOPPED WHEN IT HIT ANOTHER CAR AND THEN WE WERE UNABLE TO GET THE CAR TURNED OFF. THIS WAS NOT DUE TO THE FLOOR MAT RECALL. THE CAR WAS IN PARK AND TOOK OFF, WOULD NOT STOP EVEN WITH BOTH FEET ON THE BRAKES, IT STOPPED ONLY UPON IMPACT. LITERALLY WAS SECONDS AWAY FROM PINNING A PERSON INBETWEEN THE TWO VEHICLES. THIS COULD HAVE LED TO A DEATH OR SERIOUS INJURY. SINCE THEN THE CAR WAS REPAIRED BUT TOYOTA ENGINEERS TEST DROVE IT FOR ABOUT 10 MILES AND OF COURSE IT DIDN'T HAPPEN TO THEM SO THEY INDICATED THERE WAS NO PROBLEM. WE HAD 51,000 MILES ON THE CAR BEFORE THIS HAPPENED. CURRENTLY THE CAR SITS IN THE DRIVEWAY NOT BEING USED BECAUSE OF THE DEFECT. THIS MODEL IS NOT PART OF THE RECALL YET BUT OBVIOUSLY IS DEFECTIVE. WE HAVE TWO ADDITIONAL 2007 PRIUS MODELS IN THE FAMILY THAT ARE OF CONCERN. THIS IS OF MAJOR CONCERN AS NOTHING IS BEING DONE TO CORRECT OR ADDRESS THESE MODELS, ONLY THE NEWER PRIUS MODELS. WE SEE TOYOTA AS IGNORING THE CONCERNS ON THIS MODEL. IT IS A HUGE SAFETY HAZARD AS WHEN YOU LOOK AROUND ON THE ROADS, MANY OF THESE VEHICLES ARE STILL IN USE. *TR

MY 2005 PRIUS HAS PERIODICALLY EXPERIENCED THE MOMENTARY LOSS OF BRAKING ASSOCIATED WITH THE 2010 MODEL. THE PROBLEM HAS USUALLY OCCURRED ON A BUMPY DOWNGRADE, WITH THE BRAKES APPLIED. WHEN THE CAR ENCOUNTERED AN ESPECIALLY LARGE BUMP, OR SOMETIMES ON LEVEL GROUND WHEN IT HIT A POTHOLE, IT SUDDENLY FELT AS IF IT WERE AIRBORNE. THIS SENSATION WAS VERY BRIEF, AND THE VEHICLE ALMOST IMMEDIATELY REGAINED BRAKING EFFECTIVENESS. HOWEVER, IT WAS DISCONCERTING. *TR

I AM AN OWNER OF A TOYOTA PRIUS 2005. AFTER READING THE INVESTIGATION ABOUT THE 2010 PRIUS BRAKE PROBLEMS I FEEL I EXPERIENCE THE SAME PROBLEM IN MY CAR. WHEN BRAKE SOMETIMES IT FEELS AS THOUGH THE CAR MOMENTARILY SPEEDS UP BEFORE THE BRAKING ACTION OCCURS. IT IS BRIEF (ABOUT A SECOND IN DURATION) AND THEN THE CAR BRAKES AS EXPECTED. I HAVE ASKED THE SERVICE DEPARTMENT OF TOYOTA DEALERSHIPS I'VE HAD MY CAR SERVICED AT SEVERAL TIMES ABOUT THE SENSATION AND WAS TOLD THIS WAS NORMAL AS THE CAR SWITCH REGENERATING THE BATTERIES TO WHEN THE HYDRAULIC BRAKES ARE ENGAGED AND NOTHING TO WORRY ABOUT. I UNDERSTAND TOYOTA HAS ADMITTED A PROBLEM IN THE 2010 MODEL YEAR BUT I FEEL THE SAME PROBLEM EXISTS IN MY CAR AND WOULD LIKE TO MAKE SURE THAT THE INVESTIGATION IS NOT JUST FOR 2010 MODEL YEAR OF THE TOYOTA PRIUS. *TR

RARE BUT OCCASIONAL, SPORADIC BRAKE "FAILURE" IN 2005 TOYOTA PRIUS. LAST OCCURRENCE I REMEMBER WAS A FEW MONTHS AGO. I WAS BACKING SLOWLY INTO A PARKING SLOT ON A LOT AT A STORE. WHEN I STEPPED ON THE BRAKE PEDAL, IT FELT LIKE THERE WAS NO BRAKING FOR JUST A SECOND OR 2, THEN BRAKES ENGAGED PROPERLY. WE HAD DRIVEN SEVERAL MILES, SO ENGINE WAS WELL WARMED UP. IT WAS COLD OUT, SO HEATER BLOWER WAS BLOWING WARM AIR. *TR

WHEN CROSSING OVER UNEVEN SURFACES OR DURING WET ROAD CONDITIONS, THE BRAKES WILL OCCASIONALLY MOMENTARILY DISENGAGE WHILE THE PEDAL IS PRESSED DOWN. DURING SUCH CONDITIONS ON A HANDFUL OF OCCASIONS, I CAME VERY CLOSE TO REAR-ENDING THE VEHICLE STOPPED IN FRONT OF ME. WHEN I HEARD ABOUT THE 2010 PRIUS BRAKE ISSUE, I IMMEDIATELY IDENTIFIED WITH THE PROBLEM WHICH I'VE EXPERIENCED SINCE I BOUGHT MY 2005 PRIUS AS A NEW VEHICLE. MY PRIOR VEHICLE WAS THIS WAS AN ALL-WHEEL DRIVE SO I ASSUMED IT WAS A "QUIRKY PRIUS THING", BUT GIVEN THE RECENT NEWS, I BELIEVE THIS MAY IN FACT BE A DEFECT SIMILAR TO THAT DESCRIBED FOR THE 2010 PRIUS. EACH TIME IT OCCURS, THERE IS A FEELING OF BRIEF LOSS OF CONTROL OF THE VEHICLE WHICH IS FRIGHTENING. THE DATE PROVIDED IS THE MOST RECENT INCIDENT WHICH OCCURRED AS I CROSSED OVER A BUMPY STRETCH OF ROAD WITH UNEVEN PAVING. *TR

I DRIVE A 2005 TOYOTA PRIUS. I RECENTLY HEARD ABOUT TOYOTA ADMITTING THERE IS A PROBLEM WITH THE BRAKING SYSTEM. I HAVE EXPERIENCED THIS PROBLEM IN MY DRIVING. WHEN I EITHER BEGIN BRAKING OR HAVE BEEN BRAKING AND HIT A POTHOLE OR ROUGH PAVEMENT, IT FEELS LIKE THE PRIUS STOPS BRAKING MOMENTARILY AND THEN QUICKLY RESUMES. THE DURATION IS MAYBE A SECOND, BUT A LOT CAN HAPPEN IN A SECOND. LUCKILY THIS LAPSE IN BRAKING HASN'T HAPPENED WHEN THERE HAS BEEN A CAR RIGHT IN FRONT OF ME. I THINK IF IT DID, I WOULD HIT THE CAR BECAUSE I HAVE NO CONTROL OF THIS BRAKING LAPSE. I AM CONCERNED ABOUT THIS AND IF THIS IS A DEFECT THAT COULD BE FIXED, WHY WOULDN'T IT BE FIXED. THIS HAS BEEN AN ONGOING ISSUE FROM WHEN I FIRST BOUGHT THE PRIUS IN 2008. I DIDN'T THINK ABOUT COMPLAINING UNTIL I JUST READ THE NEWS ARTICLE RECENTLY. *TR

TOYOTA PRIUS BRAKING ISSUES - PRE 2010 MODELS. ON JAN 18TH, WHILE APPROACHING A TRAFFIC LIGHT ON WET PAVEMENT, I APPLIED THE BRAKES ON MY 2005 PRIUS AND FELT WHAT APPEARED TO BE A SLIGHT DELAY IN THE BRAKES ENGAGING. I FIRMLY BELIEVE THIS CONTRIBUTED TO MY SLIDING OUT INTO THE INTERSECTION AND HITTING ANOTHER VEHICLE. HAD I STOPPED AN INCH OR TWO EARLIER I WOULD NOT HAVE HIT THE OTHER VEHICLE. TOYOTA HAS ADMITTED TO ITS DEALERS THAT THERE ARE BRAKING ISSUES WITH ITS 2010 MODEL AND I BELIEVE THESE ISSUES MAY GO BACK TO PREVIOUS MODELS ALSO. THE HYBRID SYSTEM HAS NOT CHANGED SIGNIFICANTLY IN THE PAST 5 TO 6 YEARS. TOYOTA SHOULD BE REQUIRED TO THOROUGHLY TEST THIS SYSTEM ON ALL PRIUS MODELS. *TR

Mileage: 83,000

I READ LOTS OF NEWS REPORTS YESTERDAY THAT THE 2010 PRIUS HAS A BRAKING ISSUE WHEN RUN OVER SPEED BUMPS. MY 2005 PRIUS HAS A SIMILAR BEHAVIOR WHICH SEMI-KNOWN CAUSE WHICH MIGHT EXPLAIN THIS, WHILE BEING SLIGHTLY DANGEROUS IN ANOTHER WAY. WHEN ONE DRIVES A 2005 PRIUS TOO FAST OVER A SPEED BUMP, OR THROUGH ANOTHER SITUATION WHICH CAUSES THE CAR TO THINK ONE OF ITS WHEELS IS SLIPPING OR SPINNING AT A DIFFERENT RATE THAN THE OTHERS, THE CAR TEMPORARILY (AS I BELIEVE IS IN THE INSTRUCTION MANUAL) FLASHES A BRIEFLY APPEARING INDICATOR LIGHT ON THE FRONT PANEL INDICATING IT IS SLIPPING, AND TEMPORARILY CUTS BACK ON ENGINE POWER. AVOIDING THIS REQUIRES KNOWING THE DRIVING BEHAVIOR OF THE PRIUS, AND I WONDER IF THIS IS THE BEHAVIOR CERTAIN 2010 PRIUS OWNERS MAY BE NOTING. {IF ONE IS LOOKING AT THE ROAD AND SCARED BY THE SUDDEN DROP IN ENGINE POWER, ONE MAY NEVER LOOK DOWN AT THE DASH TO SEE THE INDICATOR FLASH FOR 1-2 SECONDS EITHER.} NORMALLY THIS IS MIGHT SEEM LIKE REASONABLE, BUT THIS BECOMES POTENTIALLY EXTREMELY HAZARDOUS SHOULD ONE TRY TO MAKE A SHARP RIGHT TURN ONTO A HIGHER-SPEED MAIN ROAD (40 MPH+) FROM A DEAD STOP ON A SIDE ROAD WITH A HIGH RATE OF ACCELERATION TO ATTEMPT MERGE INTO HIGH-VOLUME, FAST-MOVING TRAFFIC. IN SUCH CASES (ESPECIALLY IF WATER IS PRESENT, BUT EVEN IF THE ROAD IS DRY), I HAVE HAD THE ANTI-SKID FEATURE KICK IN AND CUT BACK ON ENGINE POWER FOR A HALF-SECOND OR SO, WHICH RISKS STALLING THE CAR TEMPORARILY IN FRONT OF AN ONCOMING VEHICLE. AS A RESULT, I TRY NOT TO DO ANY MANEUVERS LIKE THIS, EVEN THOUGH OTHER CARS OFTEN CAN "BURN RUBBER" A BIT AND DO THIS. NOTHING HAS BEEN DONE TO ATTEMPT TO CORRECT THE ISSUE, AS IT IS PRESUMED TO BE NORMAL BEHAVIOR FOR THE CAR, AND I NEVER HAD A CAR WITH ANTI-SKID ABILITIES BEFORE. SEEING THIS WAS COMMON FOR ME AT FIRST, BUT IS NOW SOMEWHAT RARE (LESS THAN ONCE/MONTH) DUE TO CHANGING MY DRIVING HABITS. (MY2005 PRIUS LACKS VEHICLE STABILITY CONTROL; BUT HAS THE STANDARD ANTI-SKID SAFETY FEATURE.) *TR

THE PRIUS BRAKING PROBLEM IS NOT LIMITED TO 2010 MODELS. I HAVE A 2005 PRIUS AND HAVE NOTICED THAT AFTER APPLYING THE BRAKES, IF THE CAR MOVES OVER AN UNEVEN OR SLICK SURFACE, THE BRAKES SEEM TO DISENGAGE FOR A MOMENT. AN EXAMPLE IS APPLYING THE BRAKES WHILE TRAVELING OVER A CROSSWALK STRIPE THAT HAS BEEN MOISTENED BY FOG OR RAIN. THE CAR SEEMS TO LURCH FORWARD AS THE BRAKES SEEM TO DISENGAGE AND THE SLIP INDICATOR LIGHT COMES ON. THEN THE BRAKES COME BACK ON. THIS CAN BE SOMEWHAT DISCONCERTING AND COULD BE HAZARDOUS IF THERE WERE AN OBSTACLE OR PEDESTRIAN IMMEDIATELY AHEAD. *TR

YOUR INVESTIGATION NEEDS TO GO BACK TO EARLIER MODELS! *TR

MY 2005 PRIUS HAS THE SAME BRAKING PROBLEM THAT HAS BEEN IDENTIFIED IN THE NEWS AS ONLY OCCURRING IN THE 2010 MODEL. ANYTIME I AM BRAKING AND HIT AN UNEVEN ROAD SURFACE I FEEL A LOSS OF MY ABILITY TO BRAKE. IT SEEMS LIKE THE CAR STOPS BRAKING IF YOU HIT A POTHOLE OR BUMP WHILE YOU ARE PRESSING THE BRAKE.

BRAKES HAVE BEGUN TO EXHIBIT UNUSUAL BEHAVIOR: INCONSISTENT PRESSURE TO ACHIEVE THE SAME STOPPING DISTANCE. SOMETIMES, INEXPLICABLY, THE BRAKES ARE EXTREMELY SENSITIVE...AN EXTREMELY SLIGHT PRESSURE LEADS TO A SUDDEN STOP, ALMOST LIKE THE BRAKES ARE JAMMING OR GRABBING SOMETHING INSIDE. IT'S A BIT SCARY WHEN IT HAPPENS, BECAUSE THE WHEELS FEEL LIKE THEY ARE GOING TO LOCK UP, AND IT'S HARD TO CONTROL EXACTLY WHERE THE CAR STOPS. *TR

ALTHOUGH THE CAR WAS HEAVILY DAMAGED THE AIR BAGS DID NOT DEPLOY. THIS CRASH COULD HAVE RESULTED FROM A BRAKE PROBLEM OR UNINTENDED ACCELERATION. *TR

APPLYING BRAKES WHEN GOING OVER SLIGHT ROAD DISTURBANCES CAUSES COMPLETE LOSS OF BRAKING TEMPORARILY, FOLLOWED BY A BRIEF SURGE (ACCELERATION). NO OTHER VEHICLE I'VE OWNED HAS HAD THIS PROBLEM. ADDITIONALLY SLIGHT ROAD DISTURBANCES (MILD BUMPS) CAUSE TRACTION CONTROL TO TURN ON INAPPROPRIATELY. NO OTHER VEHICLE I'VE OWNED HAS HAD THIS PROBLEM. THE DEALER (SPECIFICALLY THE SALES PERSON) WAS INITIALLY CONTACTED IN 2005 ABOUT THESE ISSUES AND IT WAS REPORTED BACK TO ME THAT THIS WAS NORMAL. NOW I AM FINDING OUT THAT MANY OTHER OWNERS ARE COMPLAINING ABOUT THIS PROBLEM, SOME OF THEM IN BRAND NEW 2010 VEHICLES.

SUDDEN ACCELERATION PROBLEM WHEN BRAKING IN LIGHT RAIN; MULTIPLE OCCURRENCES * MODEL YEAR: 2005 * MAKE: TOYOTA * MODEL: PRIUS * COMPONENT: ANTILOCK BRAKES BEFORE I BOUGHT MY CAR, I WENT ON A TEST DRIVE OF A PRIUS WITH THE SALESMAN IN THE CAR. DURING THE TEST DRIVE, IT BEGAN TO RAIN LIGHTLY. WHEN I APPROACHED A STOP SIGN, I STEPPED ON THE BRAKES, AND THE CAR SUDDENLY ACCELERATED FOR A FEW SECONDS BEFORE SLOWING DOWN AND STOPPING. I ASKED THE SALESMAN NEXT TO ME WHAT THAT WAS ALL ABOUT. "THAT'S THE ANTILOCK BRAKE SYSTEM; ISN'T IT GREAT?" IN FACT, IT WAS GREATLY TERRIFYING. WHEN I BOUGHT MY OWN CAR, I ALSO FOUND THAT IN A LIGHT RAIN, THE CAR ALSO CONSISTENTLY ACCELERATES BRIEFLY BEFORE SLOWING DOWN AND STOPPING THE CAR. THIS HAPPENED ON MANY OCCASIONS, AND NOW I DO MY BEST TO AVOID DRIVING IN THE RAIN UNLESS IT IS ABSOLUTELY NECESSARY. I REALIZE THAT THERE HAVE BEEN MANY COMPLAINTS ABOUT SUDDEN ACCELERATION LATELY, BUT THIS SEEMS TO BE DIFFERENT FROM WHAT IS BEING LOOKED AT IN THAT IT ONLY OCCURS (SO FAR) ON SLIPPERY ROADS, IT ONLY LASTS A FEW SECONDS, AND IT OCCURS WHEN I STEP ON THE BRAKES, NOT WHEN I RELEASE THE GAS PEDAL. I'VE ALWAYS ALLOWED PLENTY OF ROOM FOR BRAKING AND SO FAR HAVE NOT CRASHED, BUT I'M HOPING YOU'LL FIND A SOLUTION BESIDES LUCK TO DEAL WITH THIS PROBLEM. *TR

I WENT TO A TOYOTA SERVICE DEPARTMENT IMMEDIATELY. THEY SPENT A COUPLE OF HOURS TRYING TO FIND THE PROBLEM THIS INCLUDED DRIVING MY CAR FOR 30 MINUTES. THEY DID NOT FIND ANYTHING TO EXPLAIN THE PROBLEM. READING IN DISCUSSION FORMATS ONLINE I HAVE FOUND THIS TO BE A PROBLEM OTHERS HAVE EXPERIENCED.

MARCH 2, 2007 5:01 PM ON SEPTEMBER 7, 2006 IT RAINED AND MY CAR HAD BEEN IN THE PARKING LOT ALL MORNING DURING THE RAIN. I DROVE IT FROM WORK TO A BUS STOP WITH CLIENTS IN THE BACK SEAT. WHEN I DEPRESSED THE BRAKES, THE CAR SLOWED AND AT APPROXIMATELY 15 MPH, THE BRAKES GRABBED AND ALL OCCUPANTS WERE JOLTED FORWARD. I HAVE NEVER EXPERIENCED THIS BEFORE. THIS HAS HAPPENED REPEATEDLY WHEN THE BRAKES ARE WET FROM RAIN. AFTER DISCUSSING WITH TOYOTA I EXPLAINED THE PROBLEM TO THE TOYOTA TEAM LEADER AT MY DEALER. BEFORE TEST DRIVING THE CAR, HE SAID HE WOULD TAKE IT INSIDE AND PULL THE TIRES AND INSPECT THE BRAKES. I WAS THEN ADVISED BY SERVICE MANAGER THAT THE REAR BRAKES (DRUM) WERE FILLED WITH BRAKE DUST. I FIND IT INCONSISTENT THAT THE LARGE ACCUMULATION OF BRAKE DUST DID NOT EXIST ABOUT 8,000 MILES AGO WHEN THE GRABBING CONDITION FIRST PRESENTED AFTER I HAD DRIVEN WITHOUT THE PROBLEM FOR ABOUT 21,000 MILES. (CAR NOW HAS ABOUT 30,000 MILES.) I FIND IT VERY STRANGE THAT THE "LARGE ACCUMULATION OF BRAKE DUST" WAS NOT FOUND WHEN THE BRAKES WERE INSPECTED BY MORRISTOWN TOYOTA ON 2/16/07 WHEN THE WARRANTY WORK WAS DONE AND THE BRAKE ISSUE WAS PRESENTED. AFTER LEAVING MORRISTOWN TOYOTA I PHONED MY MECHANIC. HE SAID THAT THERE WAS NO BUILDUP OF DUST AT ANY TIME THE BRAKES WERE PULLED. I WATCHED HIM PERFORM BOTH SERVICES IN SEPTEMBER AND 500 MILES AGO (I HAVE THE NEXT CHANGE STICKER IN MY CAR SET FOR 5,000 MILES AND ONLY 500 MILES HAVE ELAPSED SINCE THE LAST CHANGE). I CHANGE THE OIL EVERY TIME THE COMPUTER INDICATES THAT THE CAR IS DUE FOR SERVICE AND, SINCE SEPTEMBER, IT WAS DURING THOSE OIL CHANGES THAT THE MECHANIC WOULD PULL THE WHEELS, CHECK THE BRAKES, CLEAN THE BRAKES (IN SEPTEMBER) AND ROTATE THE TIRES. I BELIEVE THE BRAKES ARE DEFECTIVE AND DANGEROUS. IT HAS NOTHING TO DO WITH THE REAR DRUMS SUDDENLY BEING FILLED WITH BRAKE DUST (WHICH, BASED ON THE FACT THAT THE BRAKES WERE CHECKED ON FEBRUARY 16TH BY MORRISTOWN TOYOTA, WAS GENERATED IN 2 WEEKS). *JB

EVERY TIME OUR 2005 PRIUS IS OPERATED IN RAIN SNOW SLUSH THE REAR BRAKES ARE SO GRABBY THAT IT MAKES THE CAR UNSTABLE. ON DRY DAYS BRAKES ARE FINE WHEN YOU START OUT ON WET DAYS THE ANTILOCK BRAKES ACT NORMAL AS TIME GOES ON THEY GET MORE AND MORE GRABBY TO WHERE IT IS UNSAFE. *NM

TL* - THE CONTACT HAS A 2005 TOYOTA PRIUS, WITH AN ODOMETER READING OF 18000 MILES COMPLAINED ABOUT A A MASSIVE BRAKE FAILURE. THE CONTACT STATED THAT ON 12-4-06, UNDER DRY CONDITIONS, WHILE DRIVING AT 25 MPH, SHE TRIED TO APPLY THE BRAKES WHICH FAILED. THE CONTACT WAS ABLE TO USE THE EMERGENCE BRAKE TO STOP THE VEHICLE WITHOUT A CRASH. THE CONTACT HAD THE VEHICLE TOWED TO THE DEALER., SHE HAD TAKEN THE VEHICLE TO THE DEALER SEVERAL TIMES BECAUSE THE BRAKE WARNING LIGHT KEPT TURNING ON WHILE SHE WAS DRIVING. THE DEALER TOLD HER THAT SHE DID NOT HAVE A PROBLEM WITH HER BRAKING SYSTEM. THE DEALER HAD THE REGIONAL TOYOTA REPRESENTATIVE CHECK THE VEHICLE, WHO WAS UNABLE TO FIND A PROBLEM AS WELL. THE CONTACT ALSO STATED THAT WHEN THE BRAKE LIGHT TURNED ON THE CRUISE CONTROL WAS INOPERABLE. *AK

WE KEPT HEARING A SOUND WHICH APPEARED TO BE COMING FROM THE DRIVERS SIDE AND SOUNDED LIKE A LIGHT HORN OR ALARM SOUND. IT SEEMED TO BE CONNECTED WITH BRAKING AND YET AT OTHER TIMES MY FOOT WAS ON THE BRAKE AND THE SOUND WOULD OCCUR OVER AND OVER. WE TOOK THE CAR TO THE LOCAL DEALERSHIP WHO DIAGNOSED THE PROBLEM AS A BRAKE ACTUATOR AND HAS INFORMED US THAT IT WILL COST APPROXIMATELY $2500 TO REPAIR THE PROBLEM. THIS SEEMS EXCESSIVE. IT WOULD BE NICE TO KNOW IF ANYONE ELSE HAS EXPERIENCED THIS PROBLEM. THIS IS A 2005 PRIUS. *JB

ON DECEMBER 14TH, 2006, I WAS DRIVING MY 2005 TOYTOTA PRIUS FROM BERKELEY, CA TO MONTEREY, CA. AT 18 MILES OUTSIDE OF MONTEREY. CA, AND WHILE STILL ON THE FREEWAY TRAVELING AT 65 MPH, A CONTINUOUS LOUD AND HIGH FREQUENCY BUZZER WENT ON AND THE PANEL WARNING LIGHTS WENT ON INCLUDING THE RED BRAKE LIGHT ON THE PANEL. I PULLED OFF A FREEWAY EXIT NEAR CASTROVILLE, CA AND STEPPED ON MY BRAKES TO SLOW INTO THE EXIT, THE BRAKES DID NOT WORK UNTIL I STOMPED ON THEM WITH MUCH PRESSURE. I TURNED OFF THE ENGINE, WAITED A FEW MINUTES AND TURNED THE ENGINE BACK ON. I DROVE BACK ONTO THE FREEWAY TO MONTEREY, CA AT APPROXIMATELY 35-40 MPH, WHEN I DROVE INTO TOWN ONCE AGAIN THE BUZZER AND RED BRAKE LIGHTS WENT ON.I PULLED OVER TO THE CURB AND HAD TO STOMP ON THE BRAKE AGAIN. THE CAR WAS TOWED TO A TOYOTA DEALERSHIP IN SEASIDE CA. THE VEHICLE WAS TESTED AND I WAS SHOWN A TEST FORM INDICATING THAT THERE WAS A COMPUTER MALFUNCTION LISTED AS CM1300. THE CONCLUSION OF THE MECHANIC WAS THAT IT WAS POSSIBLE THAT A REPLACEMENT PART MAY BE NEEDED WHICH WOULD TAKE A FEW DAYS AND THAT THERE WAS SOME REFERENCE TO MY USE OF SKID CONTROL AT THE TIME OF THE MALFUNCTIONS THAT I EXPERIENCED. I WAS TOLD THAT I COULD DRIVE THE CAR HOME AND THAT I SHOULD STOP EVERY 15 MILES TO STOP AND REBOOT THE CAR AGAIN TO PREVENT THE MALFUNCTION FROM OCCURRING AGAIN. I WAS TOLD THAT IF THE MALFUNCTION OCCURRED AGAIN THAT I SHOULD STOMP ON THE BRAKE REALLY HARD AND THE SKID CONTROL WOULD SOMEHOW BE ACTIVATED. I MADE IT HOME SAFELY AND DROVE AS ADVISED TO. I TOOK THE CAR THE NEXT MORNING TO BERKELEY, TOYOTA AND WAS INFORMED THAT THE TEST DRIVE AND THEIR TESTING SHOWED NO MALFUNCTION AND THAT I SHOULD TAKE THE CAR HOME, BUT THE MALFUNCTION MIGHT OCCUR AGAIN. I FIND THIS AN UNSATISFACTORY RESPONSE. I AM EXTREMELY FEARFUL OF DRIVING THE CAR WITHOUT AN EXPLANATION TO WHY THE CAR MALFUNCTIONED IN A VERY DANGEROUS WAY WHERE IT WAS DIFFICULT TO USE MY BRAKES!! *NM

WHILE STOPPED AT A STOP LIGHT, MY BRAKES FAILED AND PEDAL RELEASED TO THE FLOOR. TOYOTA OF VISALIA SERVICE MANAGER STATED THAT COMPUTER SHOWED CODES C1357 AND DETAIL CODE 28. THEY WERE UNABLE TO DETERMINE CASE OF BRAKE FAILURE, OR DUPLICATE PROBLEM. ALTHOUGH I REQUESTED THEY REPLACE COMPONENTS THAT MAY BE RESPONSIBLE FOR THE INCIDENT, GIVEN THE CATASTROPHIC POSSIBILITIES ASSOCIATED WITH BRAKE FAILURE AT HIGH SPEEDS, THEY REFUSED. *NM

DT: THE CONTACT STATED WHILE STOPPING THE BRAKES RELEASED. THE PARKING BRAKE WAS USED TO STOP THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALERSHIP, BUT THEY COULD NOT DUPLICATE THE PROBLEM. THERE HAVE BEEN NO REPAIRS MADE AT THIS TIME.*AK

2005 TOYOTA PRIUS -- FLOORMAT BECOMES LODGED BETWEEN PEDALS. -- WHILE DRIVING AT HIGH SPEEDS (60-70 MPH) ON THE FREEWAY, I NOTICED A LOSS OF SENSITIVITY ON BOTH THE BRAKE AND GAS PEDALS. I HAD TO PRESS VERY HARD TO GET A REACTION FROM EITHER PEDAL. AS A RESULT I WAS UNABLE TO KEEP DRIVING AT THE SAME SPEED AS THE SURROUNDING CARS. EVERYTHING ELSE SEEMED TO BE OPERATING NORMALLY. THE SENSATION CONTINUED FOR A FEW MINUTES UNTIL I COULD SAFELY PULL OFF OF THE FREEWAY. UPON INVESTIGATION, I REALIZED THAT THE FLOORMAT HAD COME UNHOOKED FROM ITS RESTRAINTS AND STUCK BETWEEN THE PEDALS AND THE FLOOR. I SECURED THE FLOORMAT TO ITS HOOKS ONCE AGAIN AND CONTINUED DRIVING WITHOUT TROUBLE. THIS HAS HAPPENED A COUPLE TIMES SINCE, BUT I RECOGNIZE THE SYMPTOMS AND FIX IT PROMPTLY. HOWEVER, I FEAR THAT ANOTHER OWNER MIGHT EXPERIENCE THIS WHEN THEY NEED TO BRAKE OR ACCELERATE SUDDENLY TO AVOID AN ACCIDENT. (I NOTICED ANOTHER POSTING THAT DESCRIBED THE SAME PROBLEM). PERHAPS TOYOTA SHOULD INSTALL LOCKING HOOKS RATHER THAN THE CURRENT ONES THAT EASILY TWIST AND UNHOOK FROM THE MATS.

WHILE TEST DRIVING A NEW '05 TOYOTA PRIUS I CAME TO THE CONCLUSION THAT ITS BRAKING SYSTEM IS INADEQUATE. EMERGENCY BRAKING WHILE TURNING EASILY INDUCES UNDER-STEER BECAUSE OF THE REGENERATIVE BRAKING. AS THE AGGRESSIVE BRAKE-ASSIST TAKES OVER THERE IS "SNAP" OVER-STEER AND FRONT WHEEL LOCKUP. FOR AVERAGE DRIVERS THIS CAN RESULT IN COMPLETE LOSS OF CONTROL.
