2011 Toyota Prius complaints

MY CAR SPONTANEOUSLY STARTED SHOWING THE ABS SYSTEM WARNING LIGHT, THE "BRAKE" LIGHT, AND THE ELECTRONIC STABILITY CONTROL INDICATOR LIGHT WITHOUT WARNING WHILE PARKED. AS SOON AS THIS HAPPENED AND I PUT IT IN MOTION, THE CAR BEGAN RESPONDING POORLY TO BRAKING, WITH INCREASED PRESSURE AND LACK OF RESPONSIVENESS. ADDITIONALLY, THE CAR IS RECEIVING BARELY ANY BATTERY CHARGE FROM THE BRAKES (A SMALL AMOUNT COMPARED TO THE NORMALLY FULL CHARGE), AND A WHIRRING NOISE CAN BE HEARD ABOUT EVERY 3 SECONDS ( THE SAME WHIRRING NOISE THAT OCCURS WHEN THE CAR IS STARTING UP, WHICH I THINK MAY BE RELATED TO THE BATTERY). THIS ISSUE HAPPENED WHILE THE CAR WAS AT REST, AND AFFECTS THE CAR WHILE IN MOTION AND AT REST. THE CAR FEELS UNSAFE TO DRIVE DUE TO UNPREDICTABILITY WITH THE BRAKES AND THEIR EFFECTIVENESS. I BELIEVE THIS ISSUE MAY BE ASSOCIATED WITH THE BRAKE ACTUATOR.

AFTER APPLYING BRAKES CAR CONTINUED TO MOVE FORWARD THROUGH GARAGE OPENING CRASHING INTO WALL AT END OF GARAGE BEFORE IT STOPPED. BRAKE WAS NOT SLOWING/STOPPING VEHICLE

WARNING LIGHTS FOR TRACTION CONTROL, BRAKE, AVE ALL APPEARED, AND THEN BRAKING DRAMATICALLY CHANGED. ALMOST LIKE NOT HAVING POWER BRAKES. LIGHTS WENT OFF AND NORMAL BRAKE FINCTION RETURNED. THE WARNING INDICATOR LIGHTS GO ON AND OFF, AT RANDOM. CODE C1391 SHOWS WHEN SCANNED. THIS IS SAME SYMPTOM AS EXHIBITED BY 2010 MODEL YEAR PRIUSES COVERED BY RECALL. MINE IS 2011, EXACT SAME ISSUE BUT NOT COVERED BY RECALL. PROBLEM HAS OCCURRED AT LOW 5-25 MPH AND HIGHWAY SPEEDS (55-70 MPH) THIS IS VERY DANGEROUS AS IF THIS HAPPENS AT HIGH SPEED (HIGHWAY) AND THE PROBLEM OCCURS THERE IS A SUDDEN CHANGE IN BRAKING QUALITY AN ACCIDENT MAY RESULT. THIS HAPPENS WHEN THE VEHICLE IS MOVING, AT ANY SPEED.

I HAVE AN EARLY YEAR 2011 TOYOTA PRIUS, THE BREAK BOOSTER AND MASTER CYLINDER ASSEMBLY WORK INTERMEDIATELY. SOMETIMES IT SHOWS ERRORS WITH LIGHTS ILLUMINATED ON THE DASHBOARD AND BRAKES HAVE A LOT OF PLAY AND ARE SPONGY AND OTHER TIMES THEY WORK PERFECTLY NORMALLY. THE VEHICLE WAS IN MOTION AND WHEN I WENT TO USE THE BREAKS IN A TRAFFIC SITUATION THEY ENDED UP HARDLY WORKING PUTTING MYSELF IN A HIGHER RISK FOR A COLLISION AND PUTTING MY LIFE ENDANGER.

THE CHECK HYBRID SYSTEM JUST CAME ON. WE HAVE OWNED THE CAR FOR LESS THAN 1 YEAR. ALTHOUGH IT WAS USED, IT HAS 116,000 MILES ON IT. WE DO NOT KNOW WHETHER IS A CALIFORNIA VEHICLE. WE BELIEVE IT IS A BATTERY ISSUE. THIS WOULD MEAN THAT THE BATTERY WOULD NEED TO BE REPLACED WHICH WOULD COST 2500 DOLLARS. THAT IS RIDICULOUS TO EXPECT WHEN WE JUST BOUGHT IT 1 YEAR AGO!

THE PRIUS HORN IS DEFECTIVE WHEN I PURCHASE THE CARL THE DEALER SOLD IT TO ME DEFECTIVE IT THE WASN'T WORKING AND THEY WANTED TO CHARGE ME I SPOKE TO THE MANAGER AND HE WAS ABLE TO REPAIR IT TWO YEARS LATER SAME PROBLEM I BELIVE THAT IT HAS SOMETHING TO DO WITH THE AIRBAG WHEN AM DRIVING AND MAKING A TURN THE HOUR TURNS ON WHEN I TURN THE STERING WHEEL AGAIN IT GOES OFF BUT IF I TRY USEING THE HORN NORMALY IT DOESN'T WORK AT ALL.

MY 2011 PRIUS VERY RECENTLY HAS STARTED MAKING AUDIBLY NOISE WHILE PRESSING THE BRAKE PEDAL, WHETHER IN MOTION OR STOPPED. THIS NOISE CONTAINS CONTINUOUS WHIRRING, WHINING AND LOUD CLICKING NOISE. THESE NOISES WHERE NOT SEEN BEFORE COMPLETELY. I SPOKE TO DEALER MENTIONING A TSB PERTAINING TO THIS PARTICULAR ISSUE IN SPECIFIC AND WAS TOLD NOTHING CAN BE DONE UNTIL IT FAILS COMPLETELY, WHICH IS BAD, AS I HAVE A FAMILY OF 3 AND GOD FORBID IF THIS WERE TO HAPPEN WHILE DRIVING ON FREEWAY, A SERIOUS SAFETY HAZARD AND TOYOTA DEALER (RUDY LUTHER) RESPONSE IS IRRESPONSIBLE. I AM ACTUALLY WORRIED MORE NOW ON WAITING FOR THE BRAKES TO FAIL. THIS LOUD CONTINUOUS CLICKING NOISES OCCURS THE MOMENT CAR IS TURNED ON AND THE NOISES LINGERS ON FOR SHORT WHILE AFTER THE CAR IS TURNED OFF, AT MOMENTS I HAVE TO PRESS ON THE BRAKES REALLY HARDER THAN USUAL TO GET THE CAR SLOWED AND IS A TREMENDOUS PANICKY SITUATION. I AM REGISTERING AND REQUESTING FOR THIS TO BE LOOKED IMMEDIATELY BEFORE ANY CATASTROPHE.

CAR STALLED PULLING INTO TRAFFIC. TOOK ABOUT 15 SEC TO RESTART. NO DIAGNOSTIC LIGHTS LIT UP ON DASH. CAR LOST POWER LAST MONTH AND ENGINE LIGHT WENT ON AND ENGINE COULD NOT BE RESTARTED.HAD TO BE TOWED TO DEALERSHIP. IT REPLACED VALVE ASSEMBLY FOR VACUUM AND REPROGRAMMED PCM. HOWEVER, THAT ISSUE WAS PRECEDED BY A CREEP OF DIAGNOSTIC LIGHTS (COURSE OF 1 HOUR), FROM CHECK OIL TO CHECK ENGINE, AND THEN IT COMPLETELY SHUT DOWN.

WHILE DRIVING AT CA FREEWAY SPEED (65MPH) THE CAR GOES LIMP. THE ACCELERATOR FAILS TO WORK AND EVEN FLOORING THE VEHICLE MAKES NO DIFFERENCE. AT THIS POINT THE SPEED OF THE VEHICLE DECREASES AND I HAVE TO IMMEDIATELY PULL TO THE SHOULDER. THE "CHECK HYBRID SYSTEM" ALERT SHOWS ON THE DASH AND ALSO ELECTRIC POWER STEERING AND CHECK ENGINE LIGHT. THIS ISSUE HAS BEEN GOING ON FOR THE PAST YEAR AND I HAVE TAKEN IT TO SEVERAL TOYOTA DEALERSHIPS WITH NO RESOLVE. I HAVE SPENT A TOTAL OF $4500 WITHOUT TOYOTA OF VALLEJO OR THE NOW BANKRUPT TOYOTA OF FAIRFIELD SOLVING THE ISSUE. THIS IS A LIFE THREATENING ISSUE AND HAPPENED SEVERAL TIMES WITH CHILDREN IN THE VEHICLE. SHOW IN VIDEO: HTTPS://WWW.YOUTUBE.COM/WATCH?V=CA5HJRSNFSG

BRAKES BECAME SLUGGISH. BRAKE/ABS/CAR SKID WARNING LIGHTS CAME ON.

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. WHEN THE VEHICLE WAS PLACED INTO REVERSE (WHEN THE ELECTRIC POWERED FUEL MOTOR HAD NOT BEEN RUNNING), THE BRAKES BEGAN TO SEIZE WHEN THE BRAKE PEDAL WAS DEPRESSED. THERE WERE NO WARNING INDICATORS ILLUMINATED. ALSO, DURING COLD WEATHER, THE ENGINE AND ENTIRE VEHICLE SHOOK. THE CONTACT CALLED PRECISION TOYOTA OF TUCSON (700 W WETMORE RD, TUCSON, AZ 85705, (520) 795-5565) AND NOTIFIED THEM OF THE FAILURES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 15.

AUTOMOBILE CONTINUED TO ACCELERATE AND EVEN SPEED UP WITH FOOT ON THE BRAKES. WHILE STOPPED, WAITING TO TURN, CAR WOULD STILL ACCELERATE, EVEN SPEED UP, INTO ON-GOING TRAFFIC. THIS HAS BEEN HAPPENING SINCE I PURCHASED THE AUTO, BUT IS NOW HAPPENING MORE FREQUENTLY AND FOR LONGER PERIODS. NEVER REPORTED BECAUSE IT ONLY HAPPENED FOR A BRIEF MOMENT. HOWEVER, IN THE LAST WEEK THIS HAPPENED TWICE AND I COULDN'T CONTROL THE AUTO. WAITING FOR CALL BACK FROM DEALER.

WHILE DRIVING DOWN THE HIGHWAY OR INTERSTATE, MY TRACTION WARNING LIGHT, THE BRAKE LIGHT, AND THE ABS WARNING LIGHT ALL CAME ON, AND THE BRAKES BECAME HARD TO PRESS. WHEN LETTING OFF THE BRAKE, THERE WAS AN AIRY, SUCTION SOUND. AFTER A WHILE, WHILE DRIVING, ALL OF THE WARNING LIGHTS WENT OFF, AND THE BRAKE PRESSURE NORMALIZED. THERE IS STILL AN AIRY SOUND WHEN I USE THE BRAKE PEDAL, THOUGH, WHICH ALWAYS SEEMS TO BE THERE, EVEN WHEN THE WARNING LIGHTS ARE OFF. THIS HAS HAPPENED ABOUT 4 TIMES WITHIN THE PAST SIX MONTHS. I HAD A DIAGNOSTIC TEST RUN, AND IT GAVE CODE #1391, LEAKAGE IN ACCUMULATOR ABNORMAL, WHICH POINTED TO AN INTERNAL LEAK IN THE BRAKE BOOSTER/MASTER CYLINDER ASSEMBLY. I NOTICED THAT TOYOTA HAS ISSUED RECALLS FOR THIS SAME PROBLEM IN 2010 AND PRIOR PRIUS MODELS, BUT MINE DOES NOT QUALIFY BECAUSE IT IS A 2011. SINCE THIS ISSUE HAS NOT BEEN RESOLVED AND APPEARS TO BE A DEFECT IN TOYOTA'S BRAKE BOOSTER ASSEMBLY, I WOULD LIKE TO SEE THIS RECALL EXTENDED TO COVER MODELS BEYOND 2010.

THE EMERGENCY BRAKE LIGHT, ABS, AND TRACTION LIGHTS ILLUMINATED ON THE DASHBOARD. TOOK THE CAR INTO THE DEALER AND THEY REPORTED THAT THE BRAKE BOOSTER AND MASTER CYLINDER NEEDED TO BE REPLACED. THE CAR WAS STATIONARY WHEN THE LIGHTS INITIALLY CAME ON AND THE LIGHTS STAYED ON WHILE IT WAS MOVING (HIGHWAY AND CITY STREETS). THE 2010 TOYOTA PRIUS WAS RECALLED FOR THE SAME PROBLEM. IT SEEMS THE 2011 CONTINUES TO HAVE THE SAME PROBLEM.

WE WERE ON FREEWAY WHEN AN ODD SMELL WAS DETECTED. THERE WERE SEVERAL LARGE TRUCKS IN THE AREA AND WE PASSED OFF THE SMELL TO THE TRUCKS. A COUPLE OF MILES LATER THE PASSENGER SAID, "THE FLOOR IS ON FIRE!" AT THIS POINT, AN ABUNDANCE OF SMOKE APPEARED ABOVE THE DASHBOARD ON THE PASSENGER'S SIDE. WE EXITED THE FREEWAY, FOUND A FIRE EXTINGUISHER AND WERE ABLE TO PUT OUT THE FIRE. THE LOCAL TOYOTA DEALER WAS INFORMED BUT NO ACTION WAS TAKEN. THE INSURANCE COMPANY HAS TOTALED THE VEHICLE. WE ARE AWAITING THE SETTLEMENT CHECK. WE HAVE NO IDEA WHAT STARTED THE FIRE. THERE WERE NO INDICATORS I.E. WARNING LIGHTS/BUZZERS, ETC. PRIOR TO THE FIRE. THE AREA UNDER THE DASHBOARD ON THE PASSENGER'S SIDE IS A CHARRED MASS. THEREIN A LARGE HOLE AT THE TOP OF THE DASH NEAR WHERE THE SPEAKER FOR THAT SIDE IS HOUSED. *BF*JB

MY CAR WAS PARKED ON THE STREET,I GOT INTO IT, TURNED IT ON, SHIFTED TO DRIVING AND STARTED PROCEEDING FORWARD. I THEN NOTICED 3 LIGHTS (THE ABS LIGHT, BRAKE LIGHT, AND TRACTION CONTROL LIGHT) SUDDENLY APPEARED ON THE DASHBOARD. NOTHING OUT OF THE ORDINARY OCCURRED PRIOR TO THE LIGHT COMING ON, IT JUST SUDDENLY APPEARED. THE ERROR CODE IN THE COMPUTER SYSTEM READ C1391. THE DETAILS READ THERE WAS "ABNORMAL LEAK IN ACCUMULATOR". THE CAR NO LONGER DRIVES SAFELY. IF THE BRAKES ARE PRESSED SUDDENLY THE CAR SKIDS INSTEAD OF SLOWING DOWN. IN ORDER FOR THE CAR TO COME TO A COMPLETE STOP A LOT MORE PRESSURE HAS TO BE APPLIED TO THE BRAKE COMPARED TO BEFORE ABS PROBLEM. THE STOPPING DISTANCE HAS INCREASED BY APPROXIMATELY TWICE ITS LENGTH. THE CAR IS NO LONGER CAPABLE OF SHARP TURNS, THE BACK END OF THE CAR SKIDS DANGEROUSLY LEFT OR RIGHT WHILE TURNING, DEPENDING ON THE DIRECTION THE DRIVER IS TURNING. THE BRAKING, HANDLING AND CONTROL OF THE CAR DECREASES SO MUCH WHEN THE ROADS ARE WET THAT AT TIMES THE CAR SKIDS EVEN WHEN GOING AT A CAUTIOUS SPEED IN RAIN. FOR MY SAFETY AND FOR OTHERS I DRIVE IN "B" INSTEAD OF "D" WHEN IT RAINS.

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. WHILE DRIVING ON THE HIGHWAY, THE CONTACT HEARD A LOUD SOUND. HE NOTICED THAT THE SUN ROOF EXPLODED AND THE GLASS SHATTERED. THERE WERE NO INJURIES. DCH TOYOTA OF TORRANCE (2909 CA-1, TORRANCE, CA 90505, (424) 271-2340) INFORMED THE CONTACT TO BRING IN THE VEHICLE. THE DEALER ACKNOWLEDGED THAT THE SAME FAILURE OCCURRED WITH OTHER VEHICLES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 84,360.

BRAKE LIGHT, ANTILOCK LIGHT, VEHICLE STABILITY LIGHT, AND YELLOW TRAINS CAME ON. HAVING PROBLEM WITH BRAKING. DOES NOT NOT SEEM TO BRAKE AS GOOD. IT IS VERY DANGEROUS WHEN DRIVING.

THE FOLLOWING DASHBOARD LIGHTS CAME ON ON OUR VEHICLE AT THE SAME TIME:TRACTION MODE, EMERGENCY BRAKE, ABS, AND BRAKE SYSTEM WARNING LIGHT. SINCE THE LIGHTS HAVE CAME ON, I HAVE NOTICED THAT I HAVE TO PRESS DOWN FURTHER DOWN ON THE BRAKE TO STOP THE VEHICLE. MY STOPPING DISTANCE IS FURTHER NOW AS WELL.

EXCESSIVE OIL CONSUMPTION OF APPROXIMATELY 1 QUART PER 1,000 MILES AS OF MAY 2019. TOYOTA AGREED TO DO A OIL CONSUMPTION TEST IN JULY 2017 BUT DETERMINED THAT 1 QUART PER 1,200 MILES WAS WITHIN NORMAL RANGE. CONSUMPTION PROBLEM HAS GOTTEN WORSE AND WILL PROBABLY RESULT IN HAVING THE ENGINE BLOCK REPLACED WITH A USED ONE AT A COST OF APPROXIMATELY $5,000

WELL I WAS DRIVING AND SUDDENLY MY CAR BATTERY TURNED OFF AND CHECK HYBRID SYSTEM CAME ON THE DASHBOARD IT STOPPED SO I PARKED IT ON SIDE AND UNPLUG BATTERY WIRES SO IT START WORKING AGAIN THE WEIRD THING IS THAT WHEN I CHECK TO SEE ANY CODE BUT NOTHING CAME RECENTLY IT WAS HAPPENING AND ONE RECALL CAME FOR HYBRID BATTERY AFTER THAT IT WAS WORKING FINE BUT NOW THIS THING HAPPENED AGAIN AND IT WAS DANGEROUS BECAUSE I WAS IN THE MIDDLE OF HIGHWAY AND CAR STOPPED.

STARTING FROM A STOP AFTER ENGINE SHUT-DOWN, THE CAR FELT LIKE IT WAS GOING OVER RUMBLE STRIPS. THIS GOT WORSE OVER TIME UNTIL I REALIZED THAT IT WAS ACTUALLY AN ENGINE MIS-FIRE. THE DEALER TRACED THE ROOT CAUSE TO A LEAKING CYLINDER HEAD GASKET THAT IS A COMMON FAILURE ON HIGH MILEAGE 3RD GENERATION PRIUS CARS. $4,000 REPAIR. FIRST CAR I'VE EVER OWNED THAT CYLINDER HEAD GASKETS ARE ROUTINE MAINTENANCE ITEMS. CLEAR DESIGN ISSUE. IF YOU KEEP THIS CAR LONG ENOUGH, YOU WILL BE BUYING A HEAD GASKET REPAIR.

WHEN BREAKING AND STILL MOVING, THE CAR WILL ACCELERATE MOMENTARILY RESULTING IN GOING FASTER FOR A SECOND OR TWO. THIS HAPPENED RANDOMLY OVER THE YEARS AND MAY IN SOME INSTANCES BE RELATED TO HITTING AN IRREGULARITY IN THE ROAD, BUT I CANNOT BE SURE. IT HAS NOT CAUSED AN ACCIDENT, BUT IS STRONG ENOUGH THAT IT COULD. I'M A PRETTY SAFE DRIVER SO TEND NOT TO RIDE ON THE TAIL OF THE CAR IN FRONT OF ME. I HAVE NOT KEPT TRACK OF WHEN IT HAPPENS.

MY TOYOTA PRIUS LOSES POWER RANDOMLY AFTER HAVING THE RECALL FIX J0V COMPLETED UPDATING THE SOFTWARE IN INVERTER. VEHICLE STALLED 3 TIMES ON FREEWAY, HIGHWAY AND OFF RAMP. DASH BOARD LIGHTS LIGHT UP WITH ALL WARNING LIGHTS. VEHICLE LOSES POWER....CAN DRIVE A MILE OR SO WITH ALMOST NO POWER...THEN VEHICLE SHUTS DOWN. DASH PANEL READS CHECK HYBRID SYSTEM CONDITIONS ARE EXACTLY THE SAME AS THE ZE3 WARRANTY ENHANCEMENT PROGRAM DESCRIBES. HOWEVER THE DTC CODE IS SLIGHTLY DIFFERENT SO DEALER AND TOYOTA WILL NOT FIX INVERTER. THE CAR IS DANGEROUS TO DRIVE AS THE SYMPTOMS APPEAR RANDOMLY, USUALLY AFTER AN ACCELERATION OF THE VEHICLE PUTS LOAD ON ENGINE. PLS HELP ME

THE CAR STOP WORKING ALL THE DASH LIGHTS STOP WORKING ,THE BRAKES START GETTING HARDER AND THE DON'T STOP AT ALL AND BEEPING WITHOUT STOP THAT NOISE AND THE HIBRYD SYSTEM STOP WORKING AFTER I LIVING FOR SOME RECALLS REPAIRS AND THE WANT ME TO FIX THE CAR TO PAY AND I KNOW IS NOT MY FAULT EVERYTHING IS BECAUSE IS THIS CAR IS ALL ELECTRONIC SYSTEM.NEVER ON MY LIVE I HAVE THIS PROBLEM WITH MY OTHER CARS.ONLY WITH THIS ONE AND NOW THEY ONE ME TO PAY FOR SOMETHING THE COMPANY MAKES WRONG.THIS IS NOT FAIR AT ALL.BEFORE I WAS RECOMENDED THIS CAR BUT RIGHT NOW PEOPLE ASK ME AND I HAVE TO TALK NEGATIVE SITUATION ABOUT IT.

WHEN I BRAKE ON AN UNEVEN SURFACE (POTHOLES, BUMPS, ETC) THE CAR WILL SOMETIMES JUMP FORWARDS. I AM UNSURE WHETHER IT IS REFERRED TO AS BRAKES SLIPPING BUT IT IS EXACTLY THE SAME THING THAT I'VE READ HAPPENING TO MANY PEOPLE. IT WAS AN ISSUE IN THE 2010, WHICH LED TO A RECALL, YET THERE IS NO RECALL ON THE 2011. IT DOESN'T MAKE ANY SENSE, PEOPLE HAVE SAID THAT THE ACTUATOR WAS THE PART THAT NEEDED REPLACING, YET IT IS A $3-4K PART AND SHOULD NOT BE LEFT UP TO THE CONSUMER. THIS IS A SAFETY ISSUE AND IS A KNOWN PROBLEM AND NEEDS TO BE ADDRESSED BY TOYOTA. IT HAS BEEN HAPPENING EVER SINCE I'VE OWNED THE CAR. I HAVE BEEN LUCKY SO FAR THAT IT HASN'T ACCELERATED ME INTO ANOTHER CAR OR PERSON.

WHILE DEPLOYING BRAKES IF YOU GO OVER BUMPS THEY FAIL TO BRAKE PROPERLY. FEELS LIKE A SPEED UP. THIS HAS HAPPENED NUMEROUS TIME WHILE BRAKING FOR TRAFFIC LIGHT OR MAKING TURNS.

2011 TOYOTA PRIUS. CONSUMER WRITES IN REGARD AIRBAG NOT DEPLOYING AFTER VEHICLE CRASHED AND SAFETY RECALL NO 18V-684. *AS

ALL OF THE BRAKE LIGHTS ON MY DASH LIT UP, BRAKES WEREN'T WORKING WELL, TOOK IT TO THE REPAIR SHOP AND WAS TOLD IT WAS MY BRAKE ACTUATOR.

ENGINE DEVELOPED AN OIL LEAK AROUND 120,000 MILES. DEALER RAN AN OIL LEAK TEST ($700)AND PERFORMED SOMETHING ELSE FOR $300 DOLLARS. NOTHING WORK. DEALER SAYS THE FIX IS TO BUY A NEW SHORT BLOCK FOR $6,700. I WILL NOT. I'M ADDING OIL MYSELF TO CAR ABOUT ONCE EVERY 10 DAYS

THE CAR STARTS AS NORMAL AND DRIVES NORMALLY BUT ONCE YOU START TO COME TO A STOP THE CAR SHUTS OFF AND WILL ONLY RESTART WHEN YOU DEPRESS THE GAS PEDAL BUT SHUTS DOWN AGAIN WHEN YOU RELEASE THE GAS PEDAL, NORMAL CITY STREETS AND HIGHWAY

I'M CONSTANTLY HEARING A BARKING/ PURGING NOISE COMING FROM THE BRAKE ACCUMULATOR PUMP WHENEVER I DO HARD BRAKING. WHENEVER I HIT POTHOLES OR ROUGH ROADS, THE CAR WOULD STILL ROLLS DURING BRAKING AS IF THE ABS IS GETTING TRIGGERED. I WAS QUOTED BY TOYOTA DEALER OF AN ESTIMATE OF $3000 TO REPLACE THE BRAKE ACCUMULATOR PUMP AND BOOSTER. I'M AFRAID THAT THE BRAKES WOULD FAIL WHILE DRIVING.

A FEW MONTHS AGO I HAD THE REQUIRED SOFTWARE UPDATE TO ADJUST THE SAFETY FEATURE IN THE HYBRID SYSTEM IN CASE OF A FAILURE. WHILE DRIVING ON A SIDE STREET ON 3/1/19 I PRESSED THE GAS AFTER BEING STOPPED, THE CAR JERKED, AND THE CHECK HYBRID SYSTEM LIGHT CAME ON. THIS WAS ON RAILROAD TRACKS BUT THE CAR DID DRIVE ON THE GAS ENGINE A SHORT DISTANCE TO MAKE IT OVER THE RAILROAD TRACKS. I HAD THE CAR TOWED TO A TOYOTA DEALER WHO STATED THE INVERTER WAS BAD, BUT THAT TOYOTA WOULD REPLACE IT AS THEY EXTENDED THE WARRANTY. THIS SEEMS TO BE AN ISSUE THAT TOYOTA IS IGNORING. I ALSO OWN A 2014 TOYOTA PRIUS V WHICH IS ALSO PRONE TO THIS ISSUE. TOYOTA SHOULD ADDRESS THIS ISSUE BEYOND A MERE SOFTWARE UPDATE.

I WAS ON DRIVING ON THE FREEWAY WHEN SUDDENLY TRACTION CONTROL LIGHT WAS ON AND BRAKES SEEMED TO HAVE LOCKED. THE CONDITIONS OF THE ROAD WERE DRY AND I WAS DRIVING THE SPEED LIMIT. THIS OCCURED ON A FEW DIFFERENT OCCASIONS. ONE DAY BRAKE LIGHT, ABS AND TRACTION LIGHT ALL APPEARED. TOOK IT INTO TOYOTA DEALERSHIP AND WAS INFORMED IT WAS BRAKE BOOSTER.

THE VEHICLE WAS IN MOTION. SEVERAL WARNING LIGHTS ON THE DASH CAME ON AT ONCE, AND THE BRAKES REQUIRED SIGNIFICANT ADDITIONAL PRESSURE TO OPERATE. WE DROVE HE VEHICLE HOME, AND THEN TO A NEARBY REPAIR SHOP. WE WERE INFORMED THAT THE BRAKE BOOSTER HAD AN INTERNAL LEAK, AND REQUIRED REPLACEMENT. THIS IS THE SAME PART THAT WAS ADDRESSED IN A CUSTOMER SUPPORT PROGRAM FOR THE 2010 MY PRIUS; HOWEVER, THE 0211 PRIUS IS NOT COVERED. 110,000 MILES.

TOYOTA HAD A CUSTOMER SUPPORT PROGRAM ZJB FOR DEFAULT BRAKE BOOSTER/MASTER CYLINDERS ON THE 2010 PRIUS MODELS. I HAVE A 2011 PRIUS THAT HAS BEEN DIAGNOSED WITH THE SAME PROBLEM AND THERE IS NO CUSTOMER SUPPORT OFFERED. THIS WARRANTY ENHANCEMENT ON THE 2010 MODELS IS GOOD THRU 11/30/19 REGARDLESS OF MILEAGE. EVEN THOUGH MY VEHICLE HAS THE EXACT PROBLEM THERE IS NO RECOGNITION FOR SUPPORT DUE TO THE YEAR OF THIS VEHICLE. I WAS NOT AWARE I EVEN HAD A PROBLEM UNTIL I TOOK IT TO THE DEALER FOR A SOFTWARE RECALL UPDATE. WE WERE EXPERIENCING HEAVY RAIN AND MY INDICATOR LIGHTS CAME ON WHICH IS WHY THEY CHECKED THIS AND CONFIRMED THE ISSUE ALTHOUGH MY BRAKES ARE WORKING FINE. I AM NOT UNDERSTANDING WHY TOYOTA IS NOT HONORING THE FIX FOR THE DEFAULT OR WHY AFTER DISCOVERING THIS ISSUE IN 2010 THE 2011 WOULD NOT BE CONSIDERED. I WOULD APPRECIATE SOME HELP IN THIS MATTER.

WENT IN TO HAVE THE SPARK PLUGS AND 2 COILS(CYLINDERS 1 & 2) STARTED SHAKING, KNOCKING AND SMOKING AT THE TIME I PICKED IT UP. CHECK ENGINE LIGHT IS ON AND HASN'T GONE OFF. THE MECHANIC I TAKE THE VEHICLE TO SAYS IT IS A PROBLEM WITH THIS MODEL CAR, TRYING TO DETERMINE THIS, SINCE HE STATED IT IS NOW MY HEAD GASKET THAT NEEDS REPLACING.

ALTHOUGH TOYOTA ISSUED A RECALL NOTICE IN OCTOBER OF 2018 FOR OUR 2011 PRIUS, THE AFFECTED PART WAS NOT AVAILABLE AND THE LETTER STATED WE WOULD BE NOTIFIED WHEN THE REPAIR COULD BE MADE. ON FEB. 5 OUR CHECK HYBRID SYSTEM WARNING CAME ON AND THE CAR WAS DIFFICULT TO DRIVE WITH DIMINISHED ACCELERATION/POWER--CERTAINLY A SAFETY ISSUE IN OUR AREA'S HEAVY TRAFFIC. THE AUTO NATION TOYOTA FT MYERS, FL DEALERSHIP SAID THE CAR SHOULD BE DRIVEN IN TO THE SERVICE DEPT. (BUT TOLD MY HUSBAND ONCE IT WAS THERE, IT WAS NO LONGER SAFE TO OPERATE) AND IT WOULD BE CHECKED AND THEN "GRACIOUSLY" SAID THE INVERTER SYSTEM WOULD BE REPLACED AT NO COST (APPROX. $3800) TO US AS TOYOTA OPTED TO "EXTEND THE WARRANTY". THIS SHOULD HAVE BEEN REPLACED IN OCTOBER WHEN INITIALLY NOTIFIED AND BEFORE IT FAILED AND BECAME A SAFETY ISSUE AND BEFORE WE WERE TOLD TO "DRIVE IT TO THE DEALERSHIP". I AM VERY DISAPPOINTED IN TOYOTA AND I WORRY ABOUT OTHER PRIUS DRIVERS STILL ON THE ROAD.

AIR BAGS FAILED TO DEPLOY AFTER BEING REAR ENDED STRAIGHT ON AT 55 MPH, NOT A SINGLE AIRBAG DEPLOYED.

THE FOLLOWING IS A SUMMARY OF HOW I BECAME AWARE OF THE POWER BOOSTER AND MASTER CYLINDER PROBLEM WITH MY 2011 TOYOTA PRIUS. 'UPON DISCOVERY OF MULTIPLE LIGHTS DISPLAYED ON DASHBOARD SUCH AS BRAKE, ABS SYSTEM & TRACTION LIGHTS, DURING DRIVING THE BRAKING PERFORMANCE HAS CHANGED DRASTICALLY & THE CAR NO LONGER PERFORMS BRAKING FUNCTION ADEQUATELY. UNABLE TO RELY ON SAFE BRAKING DUE TO BRAKE RESISTANCE FELT WITH STIFFENING IN WHICH PEDAL DEPRESSES DEEPLY & MORE TIME IS REQUIRED TO COME TO A FULL STOP. WHEN BRAKING THE HYBRID BATTERY DOES NOT CHARGE & RUNS DANGEROUSLY LOW RESULTING IN DAMAGE TO THE HYBRID BATTERY WHICH CAN LEAD TO SUBSTANTIAL COST TO REPLACE THE BATTERY. 'CAR BROUGHT TO FIRESTONE FOR DIAGNOSTICS. UPON FURTHER INSPECTION BY THEIR TECHNICIAN IT WAS DETERMINED THAT THE POWER BRAKE BOOSTER/MASTER CYLINDER WAS DAMAGED & MALFUNCTIONING AND WAS IN NEED OF REPLACEMENT. INFORMED REPAIR WOULD BE IN EXCESS OF $1,500.00. SEE ENCLOSED SUPPORTIVE DOCUMENTATION FROM FIRESTONE DIAGNOSTICS.

ABS ACTUATOR MALFUNCTION

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. WHILE DRIVING 65 MPH, THE BRAKE PEDAL WAS APPLIED AND WAS STIFF. THE CONTACT HAD TO TAP THE BRAKE PEDAL TO SLOW DOWN THE VEHICLE. IN ADDITION, THE BRAKE AND ABS INDICATORS WERE ILLUMINATED. THE VEHICLE WAS TAKEN TO CHARLES MAUND TOYOTA (8400 RESEARCH BLVD, AUSTIN, TX 78758 (866) 797-4354) WHERE IT WAS DIAGNOSED THAT THE BRAKE ACTUATOR NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 1901140996. NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 119,384. *TT*JB

BRAKE ACCUMULATOR FAILURE. SPECIFICALLY REPAIR T-SB-0079-18 ABS, TRACTION, BRAKE LIGHTS ON. BRAKES NOT AS RESPONSIVE/SPONGEY. NO REGENERATIVE ENERGY FROM BRAKING

THE ATTRACTION BRAKE AND ABS LIGHTS COME ON, THE BRAKE BECOME SPONGEY AND FAIL TO STOP THE VEHICLE , I ALMOST HAD AN ACCIDENT WHILE THIS HAPPENS WHILE I WAS DRIVING THE VEHICLE

ABS LIGHTS ON ,TRACKS WARNING LIGHTS ON AND VSC LIGHTS ON .ITS A SERIOUS PROBLEM. TOYOTA SHOULD FIX IT . TOYOTA SHOULD OWN ITS PROBLEM

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 18V684000 (HYBRID PROPULSION SYSTEM). THE CONTACT CALLED WESTBURY TOYOTA AT 516-272-4499 (LOCATED AT 1121 OLD COUNTRY RD, WESTBURY, NY 11590) AND WAS INFORMED THAT THE PARTS WERE NOT AVAILABLE. THE MANUFACTURER STATED THAT THE PART WAS AVAILABLE AND REFERRED THE CONTACT BACK TO THE DEALER. THE CONTACT STATED THAT THE VEHICLE STALLED WHILE DRIVING AND NEEDED TO BE TOWED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 116,480. PARTS DISTRIBUTION DISCONNECT.

BRAKE BOOSTER AND ACTUATOR FAILED AND ERROR CODE C1391. VEHICLE IS UNSAFE TO DRIVE AND TOYOTA KNOWS THIS PROBLEM BECAUSE OF THE NUMBER OF CASES INVOLVED WITH THIS ISSUE. THE YEAR PRIOR SAW A MASSIVE RECALL OF 87,000 VEHICLES WITH THE SAME ISSUE. THE SAME ISSUE HAS CARRIED OVER AND TOYOTA REFUSES TO BE HELD RESPONSIBLE FOR THIS ISSUE.

BRAKE ACTUATOR HAS GONE OUT GIVING A CODE OF C1391. I HAVE HAD THE CAR LESS THAN A YEAR AND THE BRAKES ARE NOW GRABBY AND NOT FUNCTIONING PROPERLY. THIS IS A KNOWN PROBLEM WITH THE GEN 2 PRIUS (MY PREVIOUS CAR) AND WAS COVERED UNDER AN EXTENDED WARRANTY. APPARENTLY THE GEN 3 PRIUS HAS THE SAME ISSUE AND TOYOTA HAS EXTENDED THE WARRANTY OF THE 2010 PRIUS TO THE MANUFACTURING DATE OF 11/2010. MY PRIUS WAS MANUFACTURED IN 12/2010 AND I WAS JUST NOTIFIED IT WOULD BE $4000 TO FIX THE ISSUE THAT IS A KNOWN MANUFACTURING DEFECT. APPARENTLY TOYOTA DIDN'T FIX THE PROBLEM THE FIRST TIME AND IT'S A DIRECT SAFETY ISSUE WHEN THE BRAKES DON'T WORK AS INTENDED.

MY CAR ONLY HAD 120K MILES AND THE BREAK BOOSTOR AND ACTUATOR BREAKS DOWN WHILE WE WERE ON THE ROAD. MY WIFE DRIVES THE CAR WITH MY 3-CHILDRENS. SHE WAS ALMOST HIT THE OTHER CAR ON HIGHWAY BECAUSE THE BREAKS SYSTEM STOPS WORKING AT NORMAL MODE. THE DASH BOARD SHOWS ALL KINDS OF BREAK, TRACTION CONTROL, AND ABS LIGHTS . THIS IS A LIFE THREATNING ISSUE AND TOYOT NEEDS TO REPLACE THIS PART WITH NO CHARGE BECASUE IT HAS A MANUFACTURING DEFECTS AND THOUSANDS OF PRIUS OWNER HAS THE SAME ISSU.

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 40-50 MPH, THE BRAKE PEDAL WAS DEPRESSED AND AN ABNORMAL NOISE WAS HEARD. THE CONTACT STATED THAT THE ABS WARNING INDICATOR ILLUMINATED AND THE BRAKE PEDAL WAS DIFFICULT TO DEPRESS. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED OR REPAIRED. MARIETTA TOYOTA (750 COBB PKWY S, MARIETTA, GA 30060, (770) 422-1490) WAS NOTIFIED. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 182,000.
