2011 Toyota Prius Brakes

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.

THE PROBLEM MY CAR EXPERIENCED HAPPENED WHILE THE VEHICLE WAS IN MOTION ON I-110 IN PENSACOLA, FLORIDA AND PRESENTED ITSELF ABRUPTLY (THROUGH THE CAR'S WARNING INDICATORS AT LEAST) ON FRIDAY, AUGUST 31ST HEADED TO PENSACOLA BEACH FOR LABOR DAY WEEKEND FROM OUR HOME IN BATON ROUGE, LOUISIANA. ALL THE CAR'S BRAKE WARNING LIGHTS CAME ON SIMULTANEOUSLY AND WITHOUT WARNING, THE MASTER BRAKE LIGHT, THE ABS LIGHT, FIVE DIFFERENT LIGHTS IN ALL. I PULLED OFF THE INTERSTATE, WENT TO AN AUTOZONE STORE, CHECKED THE BRAKE FLUID LEVEL AND BRAKE PADS (ALL LOOKED NOMINAL) AND GOT THE CAR'S COMPUTER CHECKED FOR WARNING CODES (NONE CAME UP). SEEING NOTHING CATASTROPHIC, BUT BEING UNSURE OF WHETHER OUR CAR WAS REALLY SAFE TO DRIVE EVEN THOUGH THE BRAKES STILL FELT FUNCTIONAL (IF A BIT OFF), WE GOT THE CAR BACK TO BATON ROUGE AND BROUGHT IT TO THE LOCAL TOYOTA DEALERSHIP'S (ALL-STAR TOYOTA, ON AIRLINE HIGHWAY) SERVICE DEPARTMENT. WE HAD NOTICED FOR SOME WEEKS PRIOR INCREASINGLY FREQUENT BUZZING SOUNDS ' ANYONE WITH A PRIUS KNOWS THESE, SUCH AS WHEN YOU TURN THE CAR OFF ' MADE BY (I'M TOLD) THE CAR'S BRAKE ACTUATOR PRESSURIZING THE BRAKE FLUID. THIS ESCALATING FREQUENCY OF THE NOISE, AND A CERTAIN CONSTANT 'PULSING' OF THE SOUND WHEN THE BRAKE WAS SLIGHTLY APPLIED, BUT NOT PUSHED DOWN TO THE FLOOR ' I NOW UNDERSTAND TO BE SYMPTOMATIC OF A FAILING BRAKE ACTUATOR. FOLLOWING SOME RESEARCH, I DISCOVERED IN 2013 TOYOTA ISSUED A RECALL FOR THOUSANDS OF 2010 PRIUS AND OTHER TOYOTA AUTOMOBILES FOR A PROBLEM WITH BRAKE ACTUATORS; ALSO, IN 2016, A WARRANTY EXTENSION AND PART REPLACEMENT WAS OFFERED TO HUNDREDS OF THOUSANDS OF 2004 THROUGH 2009 TOYOTA PRIUS VEHICLES FOR PROBLEMS WITH BRAKE ACTUATORS. IN THAT MORE RECENT MATTER, OWNERS WERE OFFERED A WARRANTY EXTENSION TO 10 YEARS AFTER FIRST USE OF THE CAR OR 150,000 MILES, OR UNLIMITED MILEAGE OR AGE UP TO THE END OF 2017.

TAKATA RECALL MY 2011 PRIUS HAS AN ISSUE WHERE THE BRAKE BECOMES SPONGY AT RANDOM WHILE DRIVING UNDER NORMAL CONDITIONS. THE BRAKE, ABS, AND TRACTION CONTROL LIGHTS ALL ILLUMINATE SIMULTANEOUSLY. AFTER RESETTING THE COMPUTER, THE ISSUE COMES BACK WITHIN 10-30 MINUTES OF DRIVING AT RANDOM. TOYOTA TOLD ME IT IS A $3,000 FIX AND THERE IS NO RECALL FOR MY YEAR. MY CAR HAS 110,393 MILES.

THE BRAKES TEMPORARILY DISENGAGED SOMETIMES WHEN BRAKING. AT AROUND 100,000 MILES, THE BRAKE ACCUMULATOR WOULD CONSTANTLY MAKE NOISES WHILE DRIVING AND AFTER SHUTTING THE CAR OFF. EVENTUALLY THE BRAKE ACCUMULATOR AND BRAKE BOOSTER FAILED COMPLETELY AT 117,000 MILES, COSTING AROUND $4,000 TO REPAIR.

THE ABS/BRAKE/SKID/WARNING TRIANGLE ON. MY 2011 PRIUS III IS 121K MILE. THIS WENT ON/OFF FOR A FEW DAYS THEN IT WAS ON THE WHOLE TIME. THE BRAKE SEEMS TO LOOSE THE HYDRAULIC POWER BRAKE. I FEEL LIKE THE BRAKES FEEL WEIRD WHENEVER HIT SMALL BUMP, BRAKE JUST FAILED FOR A SECOND. I WENT TO TOYOTA DEALERSHIP THEY SAID IT'S THE ACTUATOR THAT NEED TO BE REPLACED AND IT'S EXPENSIVE $2-3K. THEY SAID IT NEED TO BE FIX SOON BECAUSE BRAKE MIGHT FAIL AT ANY TIME. THERE SEEMS TO BE A WARRANTY ENHANCEMENT FOR THE 2010 AND OLDER BUT NOT 2011 AND NEWER. SEEMS LIKE TOYOTA STILL HAVE THE SAME ISSUE WITH NEWER MODEL, NOT FIXED YET. PLEASE BRING THIS ISSUE UP FOR SAFETY REASON.

4 LIGHTS CAME ON MY DASHBOARD: BRAKES, ABS, ETC. SO I TOOK THE CAR TO THE DEALERSHIP. THEY SAID I NEED A NEW BRAKE ACCUMULATOR BUT IT ISN'T COVERED AND IS A $3500 REPAIR. I SEE THAT THE 2010 PRIUS WAS RECALLED FOR THIS SAME PART BUT THEY WON'T COVER MINE.

THE TRACTION CONTROL LIGHT, ANTILOCK BRAKE SYSTEM NOT FUNTION AND THE LIGHT STAYS ON

THE VEHICLE TAKES LONG STOPPING DISTANCE WHILE BRAKING AND , ALSO L HAD MANY TIMES WHEN THE CAR SLIPPED WHILE BRAKING

MY BRAKES CONSISTENTLY LOCK AND THE CAR LUNGES FORWARD WHEN I HIT A POTHOLE WHILE BRAKING. THIS CAUSED A CRASH WHEN THE CAR WAS ONLY A COUPLE YEARS OLD WHEN THE BRAKES FAILED TO STOP THE VEHICLE AND IT LUNGED FORWARD INTO THE BACK OF A CAR. THIS IS EXTREMELY DANGEROUS AND I'VE SEEN THIS COMMENT OFTEN WITH THIS VEHICLE. I DON'T UNDERSTAND WHY TOYOTA HAS NOT ADDRESSED THIS ISSUE.

I WAS AT AN AUTOMATIC CAR WASH YESTERDAY AND AFTER THE WASH FINISHED I PULLED OUT OF STALL WITH HARDLY ANY BRAKES.I WAS NOT ABLE TO PUMP THEM AND HAD TO TAKE MY CAR INTO A MECHANIC THE BRAKE ACTUATOR WAS OUT AND THE CAR IS UNDRIVABLE.THE PRICE FOR THE PART ALONE IS OVER 2500.00 I WAS INFORMED BY THE DEALERSHIP THAT IS WAS A RECALLED ITEM BUT NOT FOR THE YR OF MY CAR. IF THIS WOULD HAVE HAPPENED IN TRAFFIC OR AT A HIGH RATE OF SPEED I KNOW I WOULD HAVE BEEN IN A SERIOUS ACCIDENT AND I COULD HAVE KILLED SOMEONE.

ON UNEVEN ROAD SURFACES (WASHBOARD ROAD, MANY SMALL POTHOLES, GRAVEL ROADS, ROUGH ROAD SHOULDERS) BRAKES WOULD GIVE OUT IF BRAKING HARD. IF FELT LIKE ONCE ABS KICKED IN THE BRAKES WOULD GET ALMOST COMPLETELY RELEASED. THE CAR WOULD BRAKE JUST FINE ON FLAT SURFACES, WET OR DRY. I HAVE MULTIPLE VEHICLES AND KNOW HOW ABS BRAKES WORK BUT THOUGHT THE PRIUS BRAKES WERE JUST A BIT MORE SENSITIVE AND I HAVE TO WATCH MY DISTANCES MORE CAREFULLY AND AVOID HARD STOPS. THEN ON APRIL 23, 2018 THE CAR STARTED TO MAKE SOME STRANGE NOISE BUT NO DASHBOARD LIGHTS CAME ON. I CONTINUED DRIVING AND NOTICED THE BRAKES WERE WORKING ONLY INTERMITTENTLY. AFTER I ALMOST CRASHED WHEN ATTEMPTING TO BREAK IN TRAFFIC I LIMPED BACK HOME AND TOOK THE CAR TO THE DEALERSHIP. THE REPAIRS TO REPLACE BRAKE PUMP AND CYLINDER ASSEMBLIES COST $4,193.31 BUT THE CAR WAS DRIVEABLE AGAIN. HOWEVER, I NOTICED THAT THE REPAIRS ALSO CORRECTED THE ABS PROBLEM THAT WAS PRESENT SINCE THE CAR WAS NEW. I THINK ANYONE WHO DRIVES A 2011+ PRIUS SHOULD GET THEIR BRAKES CHECKED FOR EMERGENCY BRAKING WHERE BRAKES STOP WORKING THUS ALLOWING THE CAR PLOW AHEAD EVEN IF THE BRAKE PEDAL IS DOWN TO THE FLOOR.

UNKNOWN CAUSE. THE BREAKS TEMPORARILY DISENGAGE (FOR ANYWHERE BETWEEN 1-3 SECONDS) WHEN THE CAR ENCOUNTERS A SMALL BUMP OR POT-HOLE IN THE ROAD, WHILE BREAKING DOWNHILL. USUALLY HAPPENS WHEN BREAKING HARD ON A DECLINED FREEWAY OFF-RAMP. THIS HAS ALMOST CAUSED ME TO REAR-END ANOTHER VEHICLE ON MULTIPLE OCCASIONS.

THE BRAKES ARE PUMPING SLOW SPEEDS AND THE VEHICLE MAKES MUCH MORE NOISE. THE CAR MAKES BUZZING SOUND EVERY 30 SECONDS OR SOONER. A REPAIR PERSON SAID IT IS THE ABS ACTUATOR THAT IS ABOUT TO FAIL.

WHILE DRIVING ON THE HIGHWAY, WITHOUT WARNING, I LOST POWER ASSISTED BREAKING ABILITY - ACCOMPANIED BY A NUMBER OF DASHBOARD WARNING LIGHTS. I WAS ABLE TO SAFELY STOP THE VEHICLE USING MANUAL BREAKING. I HAD THE CODE CHECKED AND HAVE LEARNED THAT THE (CODE 1391) BRAKE ACCUMULATOR FAILURE IS A COMMON ISSUE IN THE PRIUS AND HAS BEEN SUBJECT TO A RECALL/REPLACEMENT FOR THE YEARS PRIOR TO MY MAKE (I BELIEVE 2008-2010). CLEARLY THIS IS STILL AN ISSUE AND THE SUDDEN/NO-WARNING FAILURE OF THE SYSTEM CAUSES AN ALARMING AND POTENTIALLY DANGEROUS LOSS OF BREAKING CONTROL DURING HIGH SPEED DRIVING. LUCKILY, I WAS NOT USING THE BREAKS AT THE TIME OF THE FAILURE AND WAS ABLE TO DETERMINE THAT THE MANUAL BREAK PADS WERE SERVICEABLE BUT I NEEDED TO RAPIDLY INCREASE THE PRESSURE ON MY BREAKS TO SLOW DOWN SUFFICIENTLY TO AVOID AN ACCIDENT.

WHILE DRIVING ON THE HIGHWAY ALL THE BREAK LIGHTS CAME ON AND STAYED ON BRAKE, ABS AND SKID LIGHTS ON ALSO NOISE UNDER HOOD BY BRAKE MASTER CYLINDER. TOOK IT IN TO THE DEALERSHIP AND THEY VERIFIED ABS / BRAKE LIGHTS ON). TOLD ME I NEEDED TO REPLACE BRAKE ACTUATOR / BRAKE BOOSTER PUMP / BLEED / AND RE-FLASH SYSTEM . FOUND OUT THIS ALSO HAS BEEN HAPPENING ON THE 2009 AND THE 2010 TOYOTA PRIUS HYBRID AND THEY HAVE A RECALL OUT ON THIS. I WAS TOLD AT THE DEALERSHIP THAT IT WAS UNSAFE TO DRIVE THE VEHICLE WITH THIS OCCURRING

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. WHILE DRIVING VARIOUS LOW SPEEDS, THE ABS AND TRACTION INDICATORS ILLUMINATED WITHOUT WARNING. IN ADDITION, WHEN THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE LUNGED FORWARD. THE DEALER (UNIVERSAL TOYOTA IN SAN ANTONIO, TEXAS) DIAGNOSED THAT THE BRAKE BOOSTER AND THE PUMP FOR THE BOOSTER/ACCUMULATOR WERE FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED THE CONTACT WITH CASE NUMBER: 180-4162-158. THE FAILURE MILEAGE WAS 98,000.

I WAS DRIVING AT ABOUT 35 MPH AND ALL OF A SUDDEN MY BRAKES STOPPED WORKING. THE BRAKE , ABS AND TRACTION LIGHTS CAME ON ALL AT ONCE. I SOMEHOW MADE IT HOME BUT I COULD HAVE EASILY CRASHED. I HAD MY 9 YEAR OLD IN THE BACK SEAT AND HE ALSO GOT VERY SCARED. NOW I CANNOT DRIVE MY CAR AND THE BRAKES FEEL AS THEY AS STUCK AND VERY HARD. I TOOK MY CAR TO A REPUTABLE MECHANIC AND HE TOLD ME IT IS GIVING HIM CODE C1391. THIS IS THE SAME PROBLEM THAT THE 2010 PRIUS HAD UNDER THE RECALL. MY PRIUS IS 2011 AND NOT UNDER THE RECALL. I FEEL THAT THE 2011 SHOULD BE UNDER RECALL BECAUSE MANY THOUSANDS OF LIVES ARE IN DANGER NOW.

ABS BRAKE LIGHT AND TRACTION LIGHTS ARE ON. C1391 INTERNAL FAILURE IN BRAKE ACTUATOR ASSEMBLY.

BRAKE ACTUATOR FAILURE. ABS, TRACTION CONTROL, AND BRAKE LIGHT ALL ON DASHBOARD. THE CAR HAS NO REGENERATIVE BRAKING. ISSUE OCCURED RANDOMLY WHILE IN MOTION.

BRAKE ACTUATOR

WHILE IN MOTION WHEN I PRESSED THE BRAKES THE PEDAL WENT TO THE FLOOR. BRAKES FAILED. RAPID BEEPING WITH BRAKE LIGHT ON. I PUSHED ON THE BRAKES AND THERE WAS NOTHING. I DID SOME RESEARCH AND THIS VEHICLES ARE HAVING A PROBLEM WITH THE BRAKE BOOSTER ASSY. THERE IS A RECALL FOR THE SAME PARTS FOR THE 2010 PRIUS, NOT 2011 - 2015

THREE WEEKS AGO THE BRAKES FAILED AT A STOP LIGHT ON A CITY STREET AND THE ABS AND BRAKE LIGHTS CAME ON IN THE DASH. THE BRAKE FLUID APPEARED TO BE LOW SO WE OPENED A NEW BOTTLE OF FLUID AND FILLED THE RESERVOIR WHICH SEEMED TO TEMPORARILY REMEDY PROBLEM AND NOTHING COULD BE DIAGNOSED BECAUSE NO LIGHTS WERE ON IN DASH. THE EXACT SAME THING HAPPENED AGAIN WITH THE BRAKES FAILING AND THE DASH LIGHTS COMING ON WHILE AT A RED LIGHT ON A CITY STREET. WE HAD TO HAVE VEHICLE TOWED AND WERE TOLD IT WAS THE MASTER CYLINDER ASSEMBLY, BOOSTER PUMP ETC. AND WASN'T COVERED UNDER WARRANTY AT $6400. THE CAR HAS 82,925 MILES AND HAS BEEN MAINTAINED.

WHEN I GO OVER A BUMP OR POTHOLE AND PUT ON THE BRAKES THE CAR ACCELERATES. TOYOTA CLAIMS IT IS JUST HOW THE ABS BRAKES FEEL, BUT THE CAR ACTUALLY SPEEDS UP WHEN I BRAKE. HAPPENED MULTIPLE TIMES SINCE I BOUGHT THE CAR. SO FAR NO ACCIDENTS.

WHEN I'M BRAKING AND SLOWING DOWN GRADUALLY, AS WHEN APPROACHING A RED LIGHT, THE BRAKES MOMENTARILY STOP WORKING AND THE CAR FEELS LIKE IT SURGES FORWARD IF IT HITS A LOW-TRACTION SURFACE LIKE A POTHOLE OR MANHOLE COVER OR WET SPOT. I SAW THERE WAS A RECALL FOR THIS IN 2010, BUT 2011 MODEL CONSISTENTLY DOES IT AND HAS CAUSED ME AND MY FRIEND TO NEARLY REAR-END OTHER CARS WHEN DRIVING MY CAR. APPARENTLY, IT PERTAINS TO THE REGENERATIVE BRAKING SYSTEM BEING TURNED OFF WHEN THE ABS ENGAGES, LEAVING ONLY FRICTION BRAKES. THIS HAPPENS SEVERAL TIMES A WEEK ON THE WET ROADS WHERE I LIVE (NEAR SEATTLE, WASHINGTON). THIS HAS HAPPENED SINCE I BOUGHT THE CAR NEW IN 2011 BUT I'M COMPLAINING NOW BECAUSE MY FRIEND BORROWED IT AND ALMOST REAR-ENDED SOMEONE AND PUSHED ME TO REPORT IT. *TR
