2013 Toyota Prius Brakes

break booster systems fails in the ABS system, causing warning lights to come on intermittently and the breaks to not work properly. this is a known issue by Toyota that affects numerous priuses was well a large group of camry's. The company issued a Customer Service Program to address the issue but did not make extensive efforts to warn vehicle owners that this is a known problem. The fact that this issue of leaking oil in the break booster assembly is considered serious by the company and the urge you to get it repaired immediately if you become aware of it. this seems like something that should rise to the level of a product recall, not a voluntary program by Toyota. I have the documentation of from Toyota on this issue if you need it.

The contact owns a 2013 Toyota Prius. The contact stated that while driving at 25 MPH, the brake pedal was depressed but failed to respond and went all the way to the floorboard. The traction control warning light, ABS warning light, the brake warning light, and an unknown warning light illuminated. The contact stated that she continued to depress the brake pedal until it responded. The vehicle was taken to the dealer who diagnosed that the brake actuator needed to be replaced. The contact stated that the failure had been recurring while driving. The manufacturer was notified of the failure and informed the contact that they could not assist as her vehicle was 5,000 miles over the mileage for the extended warranty. The vehicle was not repaired. The failure mileage was approximately 155,000.

Hi, I have been having trouble with my car for the past few days. It is getting C1391 Diagnostic trouble Code. I have been busy with work and had to take the car to work. It has around 151,000 Milage now. I called Toyota regarding this problem and was told that my car don't qualify for Customers Support Program as it has more than 150,000 miles. I checked this website, and came know about extension till 31 August 2021 and unlimited mileage. My car starting showing up the code few days back, although I could notice chirping sound while applying brakes for past 2 years. I didn't know it was an issue. Fred Haas Toyota Country, 22435 TX-249, Houston, TX 77070 quoted around $2600 to replace the brake booster and pump. Can you please look in the matter?

Brakes were applied in order to avoid a collision with a deer, but the brakes locked up, sending my family out of control across the oncoming lane and into an embankment. They were lucky they weren’t killed. Toyota knows this is an issue and have failed to address it. The ABS accumulator no longer works, causing a dangerous situation. A local Toyota dealer alerted me to this issue.

While driving vehicle the parking brake light, abs light and traction control lights all suddenly came on. I was driving on smooth roadway with no bumps. I pulled to side to investigate to found that I had to press really hard to get brakes to function and stop the vehicle. Luckíly there were no other vehicles around.

The contact owns a 2013 Toyota Prius. The contact stated that while driving at various speeds, the vehicle would shake and vibrate while depressing the brake pedal. Additionally, while depressing the brake pedal, the vehicle would not immediately stop, causing the braking distance to become extended. The vehicle was taken to the local dealer who replaced the brake pads, but the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 108,000.

I CANNOT STOP MY CAR IN TIME, IT FEELS LIKE I AM FRED FLINSTONE TRYING TO USE MY FEET TO STOP. I HAVE REAR-ENDED ANOTHER CAR. I HAVE NO CAR TO DRIVE AS IT IS NOT SAFE. KENDALL WEST TOYOTA GAVE ME CAR BACK AND SAID PART OF RECALLS COMPLETED BUT UNABLE TO COMPLETE OTHER RECALLS. THEY SAID ABS FIXED BUT IT IS NOT AS STILL MAKES THE SAME WHINING SOUND AND I CANNOT BRAKE. I HAVE TO USE ALL MY STRENGTH TO PUSH AS HARD AS HUMANLY POSSIBLE. I HAVE TO PAY FOR RENTAL CAR. KENDALL TOYOTA COULD NOT PROVIDE A TIME FRAME OF WHEN MY CAR WOULD BE FIXED.

The contact owns a 2013 Toyota Prius. The contact stated that when he started the vehicle and depressed the brake pedal, the vehicle made abnormal whirring sounds. There were no warning lights illuminated. The dealer was not notified of the failure. The manufacturer was notified of the failure and advised the contact that they would not cover the repair of the vehicle. The contact stated that the failure had been reoccurring. The vehicle was not diagnosed or repaired. The approximate failure mileage was 116,000.

Failure of the ABS accumulator caused an accident that could have easily killed my family. The issue makes all ABS and stability control inoperable. While applying the brakes to avoid a deer at highway speeds, the wheels locked up while sending the car in an uncontrollable sideways slide across the highway and into a culvert. My wife was driving at the time and she had our 2 small children with her. I learned about the problem from the Toyota dealer and the service advisor told me that Toyota knows about this problem. The advisor informed me that it’s simply just a TSB. This is highly dangerous and Toyota should be responsible for this faulty system.

For about a week, I heard intermittent strange noises when I would be stopped in traffic with the brake pedal depressed. On 08/31/21, lights on the dashboard came on - the "brake" light, "Brake system warning light", ABS light, and the "Slip indicator" light. All of these remain on. Braking was feeling sluggish and the brake pedal would decompress to the floor when starting the car. When starting the car on 09/01/21, the car lurched forward although in "park" mode. I drove the car to the lube specialist to have them check the fluid levels, and they said that everything was o.k, nothing to make all the warning lights light up. Then I was referred to a mechanic who works on Pruis cars. His diagnostic tool was indicating that my brake accumulator was bad. This has led me to check for recalls on this model and year and it seems there have been problems submitted on this very issue.

TL* THE CONTACT OWNS A 2013 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THERE WAS AN CLICKING SOUND COMING FROM THE VEHICLE. THE CONTACT STATED THAT THE CLICKING SOUND WAS MORE EVIDENT WHILE THE BRAKE PEDAL WAS DEPRESSED. ADDITIONALLY, WITH THE BRAKE PEDAL DEPRESSED, THE VEHICLE FAILED TO STOP SLOW OR STOP AS DESIGNED. THE VEHICLE WAS TAKEN TO COBB COUNTY TOYOTA (2111 BARRETT LAKES BLVD, KENNESAW, GA 30144) WHERE THE MECHANIC DIAGNOSED THE VEHICLE WITH A DEFECTIVE RELAY INSIDE OF THE BRAKE BOOSTER. THE CONTACT WAS INFORMED THAT THE VEHICLE WOULD NOT BE SERVICED UNDER WARRANTY UNTIL A CHECK ENGINE OR SERVICE ENGINE WARNING LIGHT WAS ILLUMINATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 117,000.

MY BRAKES DON'T WORK LIKE THEY NORMALLY DO. THEY ARE HARD AND THE BRAKE PEDAL IS SPONGY. THE TRACTION CONTROL, ABS, BRAKE AND A ROUND WITH AN EXCLAMATION PINT LIGHT IS ON. IT GOES AWAY AND IT COMES BACK AND ITS VERY DANGEROUS BECAUSE IT HAPPENS WHEN I'M DRIVING AND ONCE I TRY TO STOP THE BRAKE PEDAL IS HARD. FIRST TIME IT HAPPENED I ALMOST HIT A CAR INFANT OF ME AT A STOP LIGHT. *TR

VEHICLE BRAKE ACTUATOR CONTINUOUSLY PUMPING AND RUNNING EVEN WHEN VEHICLE IS OFF OR STOPPED, ABS LIGHTS CAN LIGHT UP UNDER MODERATE BRAKING ON DRY ROADS. EARLIER GENERATIONS OF THE PRIUS HAD SIMILAR ISSUES AND TOYOTA ADDED AN EXTENDED WARRANTY TO COVER A RATHER EXPENSIVE REPAIR THAT COULD COMPROMISE THE SAFETY OF THE VEHICLE. THERE IS A WELL KNOWN ISSUE WITH THIS BRAKING SYSTEM WHEN READING FURTHER ON TOYOTA PRIUS FORUMS.

CAR FAILS TO STOP AND/OR LOSES TRACTION WHEN APPLYING THE BRAKES AT LOW SPEEDS. MY TIRE SHOP HAS INSPECTED BOTH WINTER AND SUMMER TIRES FOR TREAD AND INFLATION, SO THOSE FACTORS WEREN'T AN ISSUE DURING THE TIMES I LOST TRACTION CONTROL. EXAMPLES INCLUDE: 1) SKIDDING AND FAILING TO COME TO A COMPLETE STOP AT THE EXIT TO A DRY, PAVED PARKING LOT (FORTUNATELY MY CAR STOPPED BEFORE ENTERING TRAFFIC, BUT I SLID PAST THE ACTUAL STOP SIGN IN LINE WITH THE SIDEWALK - IT FELT LIKE I WAS ROLLING ON LOOSE GRAVEL BUT WHEN I GOT OUT AND CHECKED THE PAVEMENT WAS CLEAN); 2) FAILING TO STOP WHEN APPLYING BRAKES ON A STRAIGHT ROAD IN SNOW AS I APPROACHED A LIGHT THAT WAS CHANGING WHILE GOING ABOUT 30-35 MPH (I HAD ENOUGH STOPPING DISTANCE TO TEST EVERY BRAKING TECHNIQUE, FROM NORMAL BRAKING TO PUMPING THE BRAKES TO PUSHING THE BRAKE PEDAL ALL THE WAY TO THE FLOOR; I ENDED UP MAKING AN EMERGENCY RIGHT TURN INTO THE SHOULDER OTHERWISE I WOULD HAVE GONE THROUGH THE LIGHT INTO THE PATH OF OTHER CARS); 3) SLIDING AND FAILING TO STOP ON WINTER SIDE STREETS DESPITE ONLY TRAVELING 5 MPH BECAUSE I DON'T TRUST MY BRAKES. I'VE ALSO HAD THE TRACTION LIGHT COME ON AND FELT MY CAR SLIPPING WHEN DRIVING NORMALLY (20-25 MPH) THROUGH DRY RESIDENTIAL INTERSECTIONS WITH ENGINEERED DRAINAGE GUTTERS RUNNING PERPENDICULAR TO THE STREET, OR WHILE MAKING SLOW TURNS THROUGH INTERSECTIONS WITH UNAVOIDABLE SHALLOW POTHOLES. I TOOK THE CAR TO A TOYOTA DEALERSHIP IN OCTOBER 2019 IN RESPONSE TO A CUSTOMER SUPPORT PROGRAM NOTIFICATION THAT INDICATED MY MAKE AND MODEL MIGHT BE AFFECTED BY A BRAKE BOOSTER PUMP ASSEMBLY ISSUE, BUT THE DEALERSHIP FOUND "NOTHING WRONG" (NO WARRANTY RELATED DIAGNOSTIC CODE PER TOYOTA'S GUIDELINES) AND SUBSEQUENTLY DID NOT PERFORM ANY REPAIRS. I'VE EXPERIENCED THIS ISSUE SPORADICALLY FOR OVER A YEAR, MOST RECENT INCIDENT ON 2/3/2020.

ON MONDAY JAN, 27, 2020, I WAS INVOLVED IN THE ACCIDENT WITH MY 2013 TOYOTA PRIUS I WAS DRIVING ON A FREEWAY WITH REGULAR TRAFFIC. THE CAR IN FRONT OF ME SUDDENLY CAME TO A STOP. I IMMEDIATELY SLAMMED ON MY BRAKES VERY HARD. I HAD PLENTY OF SAFE DISTANCE BETWEEN TWO CARS. I ENDED UP RUNNING INTO THE REAR END OF FRONT CAR WITHOUT ANY NOTICEABLE SLOWDOWN. THE BRAKES DID NOT COME ON. THERE WAS NOT ANY FEELING OF GRABBING OR TIRE MAKING ANY SCREECHING NOISE. ALSO I DID NOT SEE ANY TIRE MARKS ON ROAD. ALL OF THE AIR BAGS WERE DEPLOYED AND THERE WAS A FRONTAL IMPACT. I ALSO DID NOT FEEL MY SEAT BELT TIGHTENING UP.THE BRAKES WERE NEVER FELT LIKE BEING EXERTING AT ALL. THE CAR WAS BADLY DAMAGED IN FRONT.

BRAKE ACCUMULATOR FAILURE RESULTING IN NOT BEING ABLE TO STOP PROPERLY. BRAKES BEGAN PULSATING AND MAKING SOUNDS UNDER PASSENGER SEAT. ELECTRIC PUMPING SOUND BECAME MORE AND MORE PROMINENT OVER TIME. BRAKES FAILED AND WARNING LIGHTS CAME ON, RESULTING IN INABILITY TO STOP PROPERLY, AND HITTING THE CURB IN A PARKING LOT. THIS IS OBVIOUSLY A MAJOR ISSUE WITH THE PRIUS. SERVICE MANAGER ADMITTED THEY SEE IT ALL THE TIME. WHEN I ASKED WHY WE WERE NOT NOTIFIED IN ADVANCE, THEY SAID A 'HIDDEN WARRANTY' EXISTED, BUT YOU HAVE TO WAIT FOR THE PROBLEM TO HAPPEN. THIS PROBLEM HAPPENED TWICE IN OUR 2005 PRIUS. THANK GOODNESS WE DID NOT HAVE ANY ACCIDENTS AS A RESULT OF THE BRAKE FAILURE. BRAKES ARE THE MOST IMPORTANT SYSTEM IN A CAR, AND WITHOUT THEM, WELL, YOU CAN'T STOP. PLEASE WORK WITH TOYOTA TO NOTIFY OWNERS OF THIS DANGEROUS DEFECT IN THEIR PRIUSES FROM THE YEAR 2004 ON.

EXPERIENCED WHAT APPEARS TO BE A COMMON MALFUNCTION OF THE ABS SYSTEM. WENT OVER A REGULAR ROAD BUMP ON A CITY STREET, NOTHING DRASTIC, WHILE BRAKING. IMMEDIATELY AFTER, THE TRACTION CONTROL, BRAKE, AND ABS LIGHTS CAME ON SOLID. THERE WAS STILL SOME BRAKING AVAILABLE, BUT IT REQUIRED MUCH MORE FORCE AND PEDAL TRAVEL TO ACHIEVE THE SAME LEVEL OF BRAKING AS BEFORE. THIS COULD BE VERY DANGEROUS IF SOMEONE THEN NEEDED TO STOP SUDDENLY. I WAS ABLE TO DRIVE HOME. FOUND SOME FORUMS ON LINE ABOUT THIS PROBLEM, WHICH APPEARS TO BE WIDESPREAD. USING A PAPERCLIP, I WAS ABLE TO 'RESET' THE SYSTEM, CLEARING THE WARNING LIGHTS AND REESTABLISHING ABS AND REGENERATIVE BRAKING...BUT ONLY FOR A SHORT WHILE. LATER IN THE DAY, THE SAME MALFUNCTION OCCURRED, WITH THE SAME WARNING LIGHTS APPEARING, LOSS OF ABS AND REGEN BRAKING.

SOMETHING STARTED BUZZING EVERY FEW SECONDS IN ENGINE COMPARTMENT TOWARD DRIVERS SIDE FIREWALL. AT SLOW SPEEDS, BRAKES PULSATED WITH UNEVEN BRAKING. AS TIME WENT ON, BUZZING WAS MORE FREQUENT. WARNING LIGHTS FLASHED ONCE BUT WENT OUT. AFTER THAT, WHEN PARKING CAR, THE BRAKES WENT ALL THE WAY TO THE FLOOR AND I HIT ANOTHER CAR AT PARKING SPEEDS. DEALER SAYS 'BRAKE ACTUATOR PUMP' AND WILL COST NEARLY $3000 TO FIX. THIS PUMP ALSO WENT OUT ON MY 2005 PRIUS! BUT THAT WAS COVERED BY A 'HIDDEN' WARRANTY THAT I FOUND WHILE GOOGLING THE ISSUE. WOULD HAVE PAID FULL PRICE FOR THAT REPAIR IF I HAD NOT RUN ACROSS THAT TSB. THIS IS OBVIOUSLY A BIG MONEY MAKER FOR TOYOTA FIXING THESE BUT IS A HUGE DANGER TO THE MANY DRIVERS THIS HAS HAPPENED TO OVER THE YEARS. PLEASE DO SOMETHING ABOUT IT BEFORE SOMEONE GETS HURT. IT IS A RECURRING AND SUBSTANTIAL THREAT TO DRIVER SAFETY THAT MANY DRIVERS WILL OVERLOOK BECAUSE OF THE INFLATED COST OF THE PARTS. THANK YOU.

A LOT OF LIGHTS LIT UP ON THE DASH. THE REGENERATIVE BRAKING QUIT WORKING AND THE BRAKE PADS WORE OUT REALLY QUICK.

BRAKE ACTUATOR WENT BAD AFTER RECENT (SERVICE APPT 1/26/19) INSTALL OF NEW 12 VOLT BATTERY AND SOFTWARE UPDATE DUE TO NHTSA RECALL #18V-684. WHILE TRAVELING DOWN THE HIGHWAY ON 1/30/19 LIGHTS CAME ON FOR BRAKE, ABS AND SKID CONTROL. VEHICLE WAS NOT BRAKING AT THE TIME. CONDITION CAUSED REDUCTION OF BRAKE CONTROL. THE NEXT DAY WHILE AGAIN TRAVELING ON HIGHWAY AT HIGHWAY SPEED TO TOYOTA DEALER FOR SERVICE, THE LIGHTS WENT OFF AND BRAKES WORKED PROPERLY. SERVICE WAS NOT ABLE TO RESET CODE AND I WAS TOLD THAT MEANS THE BRAKE ACTUATOR NEEDS TO BE REPLACED. I WAS QUOTED $3,400 FOR REPAIR

UNUSUAL LOUD CLICKING AND SCREECHING SOUND AS WELL AS VIBRATION FEELING UNDER THE BRAKE PEDAL WHILE PRESSING THE BRAKE PEDAL AND BRAKES DON'T FEEL POWERFUL ENOUGH DESPITE JUST GETTING NEW BRAKE PADS AT THE DEALERSHIP AND THERE IS MUCH LONGER DISTANCE NEEDED FOR BRAKING AND BRINGING TO A FULL STOP. THIS HAS PROGRESSIVELY INCREASED SINCE LAST NOTICED ABOUT 11-12 MONTHS AGO WHEN THE ODOMETER WAS AROUNT 95000 MILES. IT STARTED SPONTANEAOUSLY ON ITS OWN. THERE WAS NO ACCIDENT OR IMPACT OF ANY KIND.

2013 PRIUS 3 VEHICLE ALWAYS SERVICED AT TOYOTA DEALERSHIP, LAST SERVICE THEY RECOMMENDED FRONT BRAKE PADS REPLACEMENT, TIRES AND ALIGNMENT SO I DID . 7 MONTHS LATER DRIVING ALONG SMOOTH CITY ROAD ABS, TRACKING CONTROL, AND BRAKE LIGHTS COMES ON BRAKES FEEL HARDER TO DEPRESS AND NO GENERATIVE BRAKING. I HAD DIAGNOSTICS RUN FOR CODES AND CAME BACK (C1391 ABNORMAL LEAK IN ACCUMULATOR). RESEARCH FOUND THIS COMMON PROBLEM CRACK IN ACCUMULATOR DUE TO VIBRATION BUT FOUND NO RECALL ON IT.

SUDDENLY THE ABS, BRAKE AND THE TRACTION LIGHT CAME ON AND WILL GO WAY AFTER 20MIN. WHEN THE LIGHTS CAME ON THERE'S NO WARNING SO YOU MIGHT GET AN ACCIDENT WITHOUT BEING PREPARED FOR WORDS AS IS SO DANGEROUS TO HAVE SUCH A SAFETY ISSUE WITH THE CAR LIKE THIS.

WHEN I APPLY BREAK AT ANY SPEED (MAYBE ABOVE 20MPH) THE BREAK SYSTEM DOESN'T WORK PROPERLY. I HAVE TO PRESS THE BRAKE PADDLE REALLY HARD DOWN TO THE FLOOR. SOME TIME I EVEN HAVE TO RELEASE THE PADDLE AND THEN RE-BRAKE. THIS IS DANGEROUS, NOT SAFE AT ALL. BREAK ACTING LIKE THIS WAY SINCE I BROUGHT IT BRAND NEW. I NOTIFY DEALER TWICE TO CHECK (1ST YEAR OF SERVICE AND THEN SECOND YEAR OF SERVICE), THEY CAME BACK AND SAYS NOTHING WRONG (THIS WAS UNDER WARRANTY). NOW, WHEN I WENT TO DEALER TO REPORT THIS.. DEALER LIKE YOUR VEH IS 2013 AND HAS 10K MILES ON IT AT AUGUST, 2016, LET'S CHANGE THE ROTOR AND BREAK AND THEN WE CAN TEST IT (ARE THEY SERIOUS?). I AM SCARED TO DRIVE AND HAVE A FEELING, I WILL CRASH WITH A BRAKING SYSTEM LIKE THIS PRIUS. SOMETHING IS WRONG WITH SOME/FEW PRIUS - PLEASE ADDRESS BEFORE SOMEONE DIES.

I WAS DRIVING HOME IN MY 2013 TOYOTA PRIUS ON TUESDAY, DECEMBER 29, 2015, AT APPROXIMATELY 4:30P.M. WHILE TURNING RIGHT FROM THE STREET ON WHICH I LIVE INTO MY DRIVEWAY, THE CAR, AFTER I APPLIED THE BRAKES, SUDDENLY SURGED FORWARD. IN SPITE OF CONTINUOUSLY PUSHING DOWN ON THE BRAKES, THE CAR WOULD NOT STOP. THE DRIVEWAY SHOWS SKID MARKS FROM MY ATTEMPTS TO STOP THE CAR. THE CAR DID NOT STOP. THE BRAKES FAILED. THE CAR SHOT FORWARD, CRASHING INTO THE CLOSED WOODEN GARAGE DOOR AND THE WALL TO THE LEFT OF THE GARAGE DOOR. THE GARAGE DOOR BROKE AND ONE HALF OF THE GARAGE DOOR SPLIT AND WAS PUSHED INTO THE GARAGE. THE GARAGE DOOR COLLAPSED ON MY CAR AS WELL AS ITEMS STORED IN THE GARAGE INCLUDING PARTS OF THE GARAGE STRUCTURE AND LARGE SECTIONS OF A STORAGE UNIT, WHICH WAS BOLTED TO THE WALL. APPROXIMATELY 90% OF MY CAR WAS INSIDE THE GARAGE. I TRIED TO EXIT THE CAR THROUGH THE DRIVER'S SIDE BUT THE DOOR WOULD NOT OPEN. I CRAWLED TO THE TRUNK AREA AND COULD NOT FIND A MECHANICAL RELEASE FOR THAT DOOR. FINALLY I FORCED OPENED THE DRIVER'S SIDE REAR DOOR AND EXITED THE CAR THROUGH THE BROKEN WALL. IF THE BRAKES HAD NOT FAILED THIS WOULD HAVE NOT HAVE HAPPENED. AS A RESULT OF THE BRAKE FAILURE, I HAVE INCURRED SUBSTANTIAL LOSS, INCLUDING THE GARAGE DOOR (A TOTAL LOSS), DAMAGE TO STRUCTURAL SUPPORT TO THE GARAGE WALL, A BUILT-IN GARAGE STORAGE UNIT, CONTENTS STORED IN THE GARAGE AND SUBSTANTIAL DAMAGE TO THE CAR. FORTUNATELY, I DID NOT SUFFER ANY MAJOR PHYSICAL INJURIES, ALTHOUGH FOLLOWING THE COLLISION I EXPERIENCED AND CONTINUE TO EXPERIENCE MUSCLE, JOINT, HIP, NECK AND BACK PAIN AND DISCOMFORT. IN ADDITION, I CONTINUE TO EXPERIENCE EMOTIONAL DISTRESS FROM THIS INCIDENT. I WANT TOYOTA TO PERFORM A COMPLETE DIAGNOSTIC SAFETY CHECK OF ALL SYSTEMS INCLUDING THE BRAKES AND ANY SOFTWARE THAT CONTROLS THE BRAKING SYSTEM.
