  The brake system is constantly failing/malfunctioning.It is available for inspection upon request. There has been several incidents where other vehicles have nearly been rear ended. I took my 2011 Toyota Prius (hybrid) to Toyota approximately 8 months ago. They/Toyota did confirm that the problem was indeed the brake booster. The warning lamps did come on soon as the brakes started malfunctioning.

  I have a 2011 Toyota Prius with 85K miles, as I was driving on the highway the abs light, brake light, and TSV light came on and then brakes were not working like normal. Had to pump the brakes very rapidly and steer off to the right side of the highway and use the emergency brake to come to a complete stop. I called the Toyota dealer and they said its the brake accumulator fault and they will not cover the fix because it was out of the 10year/150K mile warranty per SB. Towed my car to an independent service center and they confirmed it was the brake accumulator C1391 code. cost me $3000 to fix.

  THE CAR SUDDENLY DECELERATED FROM 65 MILES AN HOUR TO ABOUT 5 MILES PER HOUR WHILE DRIVING ON A HIGHWAY AT NIGHT WITH THE SHOULDER BLOCKED DUE TO ROAD CONSTRUCTION. THIS SAME PROBLEM WAS PRESENT IN THE 2004 PRIUS AND WAS APPARENTLY THE SUBJECT OF NHTSA INVESTIGATION. THERE WAS A RECALL ISSUED ON NOVEMBER 30, 2010 FOR 650,000 UNITS OF THE 2010 PRIUS. TOYOTA HAS NOT BEEN ABLE TO DETERMINE THE CAUSE OF THIS PROBLEM IN THE EARLIER MODELS AND ADMITS IT DOESN'T KNOW THE CAUSE OF THE PROBLEM IN THE 2011 PRIUS. THIS DEFECT PRESENTS A GREAT DANGER, ESPECIALLY WHEN DRIVING IN HEAVY TRAFFIC AT HIGHWAY SPEEDS. *KB

• 12/21/2024· SERVICE BRAKES

  All brake lights on Dashboard came on. Almost got into an accident because brakes were not responding. Brakes started responding but lights remained on. At time it will contibue to beep and Brakes do not respond. I am seeing that this is a common issue happening to most Prius vehicles after a certain period. It is extremely expensive to repair. Since this is happening on quite a lot of Prius vehicles, I feel this should still be covered by Toyota. This appears to be a faulty Brake Pump and Brake Booster. This has not been inspected by a dealer but being that the car is a 2011, I'm afraid they will decline from what I have been reading.

  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.

  I have reported this once and numerous times to Toyota. I even paid to "fix" the problem. My daughter was driving and all the dashboard lights came on and the brakes do not work. It's doing it again after they supposedly "fixed" it. My family is at risk! If anything happens, I will seek legal action. I can't believe a company as big as Toyota wont take responsibility. And that a recall wont be done. I've seen numerous people report the same issue. PLEASE do something.

  The Master Cylinder started failing while I was driving the car, the car only has 138k miles, the dashboard lit up like a Christmas tree, all the warning lights were on, and when I went to step on the brake, I had to push it all the way to the floor for any braking to happen. I remember being scared for my life because I had almost no brakes which I could've got into a serious accident or been killed had it failed completely. I took the car to the dealer and they diagnosed it with code C139: Abnormal Leak at Accumulator Assembly, and recommended a new Brake Booster with Master Cylinder Assembly and Brake Booster Pump Assembly with Bracket. The car by age was not in Toyota's extended warranty on the parts but mileage-wise it still is, so I was footed with a $4-5k bill to replace both parts.

  ON DECEMBER 8TH, 2018, I WAS DRIVING EASTBOUND ON INTERSTATE 10 IN PHOENIX, AZ AT APPROXIMATELY MILEPOST 141 AROUND 5:45 PM. SUDDENLY, I HEARD A LARGE, *BANG* WHICH SOUNDED LIKE A GUNSHOT. I IMMEDIATELY CHECKED MYSELF FOR INJURIES AND FELT THE CAR TO DETERMINE IF A TIRE WAS BLOWN. I WAS INTACT, AND THE TIRES SEEMED OK AS WELL, BUT I HEARD THE NOISE OF AIR ESCAPING FROM THE VEHICLE. AFTER TURNING SOUTH ON I-17, I EXITED ON THE FIRST STREET, EXIT 199, JEFFERSON ST. I TURNED LEFT AND LOOKED FOR A SAFE PLACE TO PULL OVER. IT ISN'T A GOOD NEIGHBORHOOD, SO I SLOWED DOWN AND CONTINUED TO LOOK AROUND THE VEHICLE AS I TRIED TO FIND THE PLACE WHERE THE AIR WAS ESCAPING. FINALLY, I CRACKED OPEN THE SLIDING DOOR AT THE TOP OF MY SUNROOF, AND I NOTICED SHARDS OF GLASS. I IMMEDIATELY CLOSED IT AND WAS RELIEVED IT HAD NOT BEEN OPEN WHEN THIS INCIDENT HAPPENED. I DECIDED I MUST GET HOME IMMEDIATELY, PROCEEDED BACK TO THE FREEWAY, AND DROVE HOME. WHEN I ARRIVED, I NOTICED THE SUNROOF WAS SHATTERED - ONE MAIN HORIZONTAL SHATTER AT THE CENTER AND TWO MORE VERTICAL SHATTERS AT EACH END. I CHECKED THE INTERIOR OF THE VEHICLE FOR A PROJECTILE AND FOUND NOTHING. AFTER RESEARCHING FURTHER, IT WAS CLEAR THAT THE GLASS HAD BROKEN SIMPLY DUE TO POOR DESIGN. I IMMEDIATELY FILED A CLAIM WITH MY INSURANCE COMPANY, FARMERS. THE CLAIM NUMBER IS 910380. I HAVE ALSO CONTACTED TOYOTA TO GET A RESPONSE, BUT I HAVE NOT HEARD BACK. I AM FORTUNATE THAT THE SUNROOF WAS NOT EXPOSED. THERE IS A PAPER-THIN SLIDING DOOR THAT BLOCKS THE SUN. EVEN THOUGH THE SUN HAD SET, I HAD LEFT IT CLOSED, AND IT PROTECTED ME FROM THE SHARDS OF GLASS. THIS IS CLEARLY A DEFECT THAT TOYOTA NEEDS TO ADDRESS. IT IS DECEMBER IN ARIZONA, AND THE TEMPERATURE WAS 69 DEGREES WHEN I LEFT TO RETURN HOME YESTERDAY. IT'S NOT A HEAT ISSUE. IT'S LIKELY A GLASS DEFECT. I LOOK FORWARD TO OBTAINING MORE INFORMATION.

  ON NOVEMBER 4, DURING A ROUTINE MAINTENANCE APPOINTMENT, IT WAS DISCOVERED THAT OUR PRIUS IS COMPLETELY INVADED WITH MICE, FROM WHERE THE WIND SHEILD MEETS THE DASHBOARD, ALL THE WAY THROUGH THE ENTIRE CAR - BETWEEN THE VISIBLE INTERIOR AND THE METAL FRAME - TO THE REAR HATCH DOOR LATCH. WE LEARNED THAT TOYOTA IS WELL AWARE OF THIS PROBLEM,​ DUE TO HOW IT IS DESIGNED, WHICH GREATLY ALLOWS FOR RODENTS TO ENTER THE CAR'S CABIN AND TRUNK AREA VIA THE HEATER BOX AND CABIN FILTER AREA. THIS IS A PARTICULAR HEALTH HAZARD....A SIGNIFICANT ONE. TO REMEDY THE ISSUE THE SERVICE DEPARTMENT HA​D​ TO LITERALLY STRIP THE ENTIRE INTERIOR OF THE CAR DOWN TO THE METAL, FROM WINDSHIELD TO TRUNK LATCH. EVERY THING HA​D​ TO BE TAKEN OUT, SEVERAL PARTS REPLACED (INCLUDING THE CARPET WHICH WAS DAMAGED ON THE UNDERSIDE), OR CLEANED AND REINSTALLED. THIS COSTS THOUSANDS OF DOLLARS AND OVER A MONTH OF TIME. I HAVE INVOICES AND STATEMENTS BUT DO NOT KNOW HOW TO CONVEY THOSE TO YOU, BASED ON THE INSTRUCTIONS GIVEN.

• 12/06/2024· EXTERIOR LIGHTING

  Attached is a report from the Florida Attorney General's project office. Vehicle front headlight bulbs burn out prematurely and frequently and without warning causing reduced visibility at night on dark roads. This is a common and on-going problem for Toyota and other manufacturers and me. Toyota recognized this and issued its own recall ending in 2019, but my car was missed. The 'fix' for me is advice that I should drive my car with high beams on, but in bad weather or on-coming traffic this fix is also a safety hazard. My fear is that one night both bulbs will go out and I will be unable to see the roadway. My car is available for inspection. Constantly replacing bulbs has been and continues to be an expensive issue.

• 12/05/2024· SERVICE BRAKES

  I have been doing some research, and the brake actuator and ABS system failing is a common problem on these cars. Mine recently started acting up and they used to replace it for free. I got my Prius only 6 months ago and have not had any luck getting Toyota to replace it. This needs to be recalled it is a serious safety hazard if the brakes suddenly give out. They should be replacing this free on all cars having this issues and they are aware of the issue (Toyota). The brakes suddenly stopped working well and lights came on in this exact instant on the interstate. This first happened about a month ago. Tons of people are making complaints with the NHTSA for the same issue.

  12 months ago we noticed a vibration while braking at very slow speed/creeping forward that worsened over time. We didn’t understand the significance at the time. In addition, we noticed more recently the brake pump running more and more frequently, even when the brakes weren’t being pressed. We suspect some sort of problem with the brake booster. This has had many claims against Toyota where my break booster is going out, and I have called toyota to assist since they've had a class action lawsuit that caused them to assist with recalls on vehicles; however the year my vehicle does not qualify for a recall. They opened a service case# 241010002348, but told me it would have to be an out of pocket expense since there's nothing they can do. Unfortunately this is a failure defect on the manufacturers production. Please help.

MY FRIEND WENT TO RAISE MY WINDOW BECAUSE HE WANTED THE A/C ON. HE USED HIS AUTO UP FEATURE FROM THE DRIVERS SIDE. BEFORE I COULD REMOVE MY ARM, THE WINDOW WAS ALREADY MOVING UP. IT STARTED TO SQUEEZE MY ARM IN THE VERTICAL POSITION. I HAD MY THUMB INSIDE THE VEHICLE AND MY FOUR FINGERS OUT SIDE THE WINDOW FROM THE TOP. I COULD NOT RELEASE MY HAND FROM EITHER DIRECTION. MEANWHILE THERE WAS A TREMENDOUS AMOUNT OF PRESSURE FROM THE BOTTOM. SO BAD, I STARTED TO YELL AT MY FRIEND TO LOWER THE WINDOW. HE SAID IT WOULDN'T GO DOWN. I STARTED TO PANIC BECAUSE THE PAIN WAS VERY BAD. I WAS ABOUT TO PUNCH THE WINDOW BUT QUICKLY REACHED ACROSS MY BODY USING MY LEFT HAND. I USED MY PASSENGER SIDE WINDOW CONTROL AND WAS ABLE TO LOWER THE WINDOW. THIS SO-CALLED AUTO-DOWN PINCH PROTECTION DOES NOT ACTIVATE RIGHT AWAY. I FIRMLY BELIEVE IT ACTIVATES ONLY PAST A CERTAIN POINT. ACCORDING TO TOYOTA'S WEBSITE, THIS FEATURE SHOULD APPLY TO ALL POSITIONS BUT IN FACT DOES NOT. THE BACK OF MY ARM WAS SORE FOR DAYS AND DID BRUISE. WE TESTED MY FRIENDS CAR AGAIN ANOTHER DAY AND DISCOVERED THE EXACT SAME THING HAD HAPPENED AGAIN. THIS TIME WE ONLY USED OUR HANDS TO APPLY PRESSURE AT THE VERY BOTTOM INSTEAD OF ONLY AT THE TOP OR IN THE MIDDLE. THIS IS A HUGE CONCERN. TOYOTA WAS EMAILED BUT I HAVEN'T HEARD BACK FROM A REPRESENTATIVE. IN MY OPINION, I SHOULD HAVE RECEIVED AN EMAIL BACK OR A PHONE CALL AT THE LEAST.

NEEDLESS TO SAY THIS WAS A CATASTROPHIC FAILURE OF THE ENTIRE BRAKE SYSTEM ON A CAR THAT HAS A CUSTOMER SUPPORT PROGRAM NOTIFICATION FROM TOYOTA[ZJB] THAT WAS SENT TO ME WITH A WARNING OF SUCH OCCURRENCE. THIS IS DOWN RIGHT IRRESPONSIBLE TO A MAJOR CAR MANUFACTURER TO ALLOW THESE VEHICLES ON THE ROAD WITHOUT TESTING THE ENTIRE SYSTEM ON EACH OF THESE AFFECTED VEHICLES AND WITH FOR A CATASTROPHIC FAILURE TO OCCUR AND CAUSE PUBLIC HARM OR EVEN DEATH. I HAD JUST TAKEN THE VEHICLE FOR SERVICE A FEW WEEKS PRIOR WHERE I EXPLAINED THE SERVICE ADVISOR OF AN ISSUE WITH BRAKE PULSATION. HOWEVER, THE ENTIRE BRAKE SYSTEM WAS NOT THROUGHLY CHECKED AND WAS JUST TOLD THAT ITS THE FRONT ROTORS THAT ARE UNEVEN, THANK GOD I DID NOT FULLY LOOSE CONTROL OF THE VEHICLE AND CAUSE A CATASTROPHIC ACCIDENT AS IT WOULD HAVE RESULTED IN BODILY HARM TO MY FAMILY. I EXPECT THIS FEDERAL GOVERNMENT AGENCY TO USE IT'S AUTHORITY TO PREVENT SUCH OCCURRENCE TO THE TAX PAYING CITIZENS OF THIS NATION.
