I am looking to receive a little bit more assistance regarding my daughter's first car that she worked very hard for. It is a 2006 Toyota Prius. It was garage-kept and owned by an older couple who only put 85,000 miles on it. It is really a gem of a car. Soon after we registered the car, my daughter was out driving with her father. While going through a 4-way stop, she found that the brakes had failed and she was unable to stop at the intersection. Luckily, she was with her father, and he was able to give her verbal instruction to guide the both of them to safety. Upon further investigation, we learned that there was a recall on the Brake Actuator Assembly in 2016. Which is the part that has failed and almost caused my 16 year old daughter to crash the car she worked hard for. I contacted the Toyota Brand Engagement Center. It was stated to me that the recall has expired, however, I feel that the fact that a recall was issued means that it was recognized by Toyota that the vehicle was sold with a faulty brake system. This, in and of itself, is a hazard and could be fatal. This should be addressed and the brake system should be replaced as it is no fault to any owner regardless of the recall expiry date. We look forward to your timely response on how we can remedy this very serious safety issue. My daughter was super excited as she worked very hard to save up for her first Toyota and get it registered only to find that the brake system fails.
The actuator failed. The car is no longer safe to drive. This is a known issue. The company refused to fix the issue or recall the car. The warning lights and a loud beep are present if the vehicle is started.
The ABS Sensor on the brakes failed while driving on the highway. This could have caused an accident. These modules should last the lifetime of the car.
my 2006 prius has 170000 miles, recently has abs brake actuator making sounds everytime when turn off.
Brake actuator is not working properly and will eventually get us in an accident. We bought the car brand new. There is a recall for this issue, but we were never notified by Toyota. After contacting Toyota, they claim we are out of the recall dates and will do nothing. I have requested a copy of the letter they should have sent you notifying us of this issue. They cannot provide one. I would like to be able to fix this car; I cannot afford another car or such an expensive repair caused by a defective Toyota part. Please, help us. Thank you.
The abs actuator is bad. Cant stop nor use the rechargeable braking. Very dangerous.
The contact owns a 2006 Toyota Prius. The contact stated while getting into the vehicle, there was a loud buzzing sound coming from the brakes. The contact stated that the brake, anti-slip regulation, ABS, and vehicle stability control warning lights were illuminated on the instrument panel. The contact stated that the brake was inoperable. The vehicle was taken to an independent mechanic and diagnosed with an accumulator failure. The part was replaced; however, the failure recurred consistently. The manufacturer was not notified of the failure. The approximate failure mileage was 243,000.
In June of 2018 My brake actuator failed on my 2006 Prius. At that time I had 169,689 miles on the vehicle. I had the part replaced at Autonation, a Toyota dealership for $2626 . Recently I had noticed that while sitting at a stoplight I was hearing a tapping noise at the brakes along with what they refer to as a 'seal bark'. The same sounds the car was making just before the actuator failed three years before. A few days later I was driving south on highway 19 in Saint Petersburg during a light rainstorm. Traffic slowed quickly in front of me. I pressed on the brake pedal and the brakes locked up. The ABS was not working. I was barely able to avoid a crash. On September 27th I took the car to the same Toyota dealership that had replaced the actuator three years earlier. I told them about the noises at the brakes and told them these were the same sounds the car was making when the actuator failed the first time. They checked it out and told me that everything was working fine and that the car was not issuing any error codes. They could hear the same noises that I could, but said that I would need to continue to drive the car until the actuator failed to the point that it lit up dash lights or issued error codes. I logged on to PriusChat to search for what other people were seeing. I am not alone in this. Many others have had the same experience with the dealerships saying 'drive it till it fails'. Drive it until you lose your brakes? If I'm in this situation, then how many other Prius owners are driving around with dangerous brakes. I have no choice but to wait until the failure gets worse. If you search results on PriusChat for 'actuator', I think you will see that this probably means that there are thousands of cars just like mine out there on the roads. I got 169,689 miles out of the first actuator and just 22,000 out of the second one. Based on what I've seen on PriusChat, the new part seems to be worse than the original part.
Vehicle, upon turning on ignition/starting and putting in either drive or reverse gear, on level surface with brakes still applied will roll forward or backward. This has happened several times but usually at first start up for the day No warning lights(brake or other) are displayed Brake pedal is firm /no problems with pads/shoes ,brakes work fine any other time. I have called the local toyota dealer and toyota(company) and told them about this safety issue but was told i would have to pay to get it diagnosed . No one other than my wife child and i experienced this problem . Fortunately no one has gotten hurt. Was suprised to learn that this problem is not a part of a recall.
THE BRAKE BOOSTER IS MAKING LOTS OF CHIRPING NOISE WHEN THE BRAKE PEDAL IS DEPRESSED. WHILE I AM NOT GETTING ANY VISUAL INDICATORS OF FAILURE AT THIS MOMENT I BELIEVE (DUE TO MY OWN RESEARCH) THAT WHEN I DO THERE IS A HIGH CHANCE OF ME GETTING INTO A CAR ACCIDENT. I HAVE READ ON PRIUSCHAT.COM THAT SEVERAL PEOPLE HAD BRAKE FAILURE DUE TO THE FAULTY PUMP WHICH CAUSED A CAR WRECK. THIS IS A DANGEROUS PREDICAMENT TO BE IN AND TOYOTA SHOULD EXTEND THEIR WARRANTY TO COVER THE FAULTY EQUIPMENT THEY HAVE INSTALLED ON THESE VEHICLES BEFORE SOMEONE GETS SERIOUSLY HURT OR DIES.
WHILE VEHICLE WAS IN MOTION ON A CITY STREET, AND ALSO UPON BACK ROADS, THE BRAKES IN MY 2006 TOYOTA PRIUS SEEMED TO GRAB. THERE WAS ALSO A LOUD NOISE UPON BRAKING. THIS ISSUE WORSENED AND THE DASH LIGHTS LIT UP. I TOOK TO LOCAL TOYOTA DEALERSHIP AND IT WAS DETERMINED THAT THE BRAKE ACTUATOR NEEDS TO BE REPLACED DUE TO SAFETY ISSUE OF BRAKES GOING OUT IN THE FUTURE. (NOT IF BUT WHEN). I WAS TOLD WHEN THE BRAKES GO OUT, I AM TO PUSH THE EMERGENCY BRAKE AND THE VEHICLE WOULD COAST TO A STOP. THIS IS AN UNSAFE CONDITION AND COULD HAPPEN WHILE BRAKING FOR A RED LIGHT OR BRAKING TO AVOID HITTING A DEER. THE COST TO FIX THIS BRAKE ACTUATOR ISSUE WILL BE APPX $3000. UPON FURTHER RESEARCH, TOYOTA KNEW OF THE ISSUE AND OFFERED AN EXTENDED WARRANTY THAT EXPIRED DEC 2017. THERE ARE SEVERAL OTHER COMPLAINTS OF THIS SAME ISSUE WITH OTHER '06 PRIUS OWNERS OF THIS HAPPENING BEFORE AND AFTER THE WARRANTY EXPIRED IN DEC OF 2017. THIS IS A SAFETY ISSUE WHICH COULD CAUSE INJURY OR DEATH WHEN THE BRAKES DO STOP WORKING AND NEEDS TO BE A RECALL, NOT AN EXTENDED WARRANTY THROUGH TOYOTA THAT EXPIRES.
ABS WARNING LIGHT ARE NOW ON. FEEL CAR IS LOSING BREAK CAPABILITY. NO ACCIDENT BUT DO NOT FEEL CONFIDENT WITH THE BRAKE CAPACITY. TODAY I TOOK THE CAR TO THE DEALER AND THEY STATED THAT THE ABS ACTUATOR ASSEMBLY (CODE C1391) NEED TO BE REPLACE. LOOKING IN THE INTERNET AND IT LOOKS A VERY COMMON DEFECT FOR PRIUS. THIS IS A PRIUS 2006 WITH 163.000 MILES. TOYOTA KNOW ABOUT THIS, EXTENDED WARRANTY, BUT I AM OUT OUT THIS EXTENSION. BUT THIS SYSTEM SHOULD PROPERTY WORK FOR THE LIFE OF THE CAR.
BREAKS, IBS AND OTHER LIGHTS CAME ON DURING A ROAD TRIP. BREAKS SIENGSGED AND I HAD TO PRESS HARDER AND 'PUMP' IN ORDER TO BREAK. TOOK TO MR. TIRE TO CHECK -AND REPLACED BREAKS AND FLUSH. LIGHTS STILL ON. TOOK TO THE DEALER- IBS ACTUATOR ASSEMBLY FAILURE. QUOTED REPAIR OVER $2400. APPARENTLY, SOME OWNERS OF THIS MODEL RECEIVED LETTER FOR WARRANTY AND EXTENDED WARRANTY FOR ACTUATOR ASSEMBLY. DEALER DID NOT MENTION THIS OPTION AT ALL.

WHILE I WAS DRIVING ON THE HIGHWAY CRUISING AT HIGHWAY SPEED I SUDDENLY RECEIVED A LOUD CONTINUOUS BEEP AND MY ABS , BRAKE , AND (!) ILLUMINATED. I ATTEMPTED TO STOP AND I HAD NO BRAKES EXCEPT WHEN THE PEDAL WAS ALL THE WAY TO THE FLOOR IT FELT AS IS IT WAS JUST PULLING THE REAR DRUMS. IT TOOK A WHILE TO STOP AND I SIDE SWIPED THE MEDIAN BARRIER TO AVOID A COLLISION WITH THE VEHICLE IN FRONT OF ME AS TRAFFIC WAS BUILDING. I ASSUME IT WAS THE BRAKE ACTUATOR THAT THERE WAS AN EXTENDED WARRANTY FOR ALMOST A DECADE LATER BUT NO RECALL. FOR SOMETHING SO DANGEROUS I CAN'T IMAGINE HOW THAT ISN'T A RECALL.
ABS ACTUATOR FAILURE. THERE WAS A RECALL THAT WAS GOOD UNTIL 2017 AND 150K MILES. MY VEHICLE HAS 192K MILES. I WAS BACKING OUT OF MY DRIVEWAY AND THE THREE ABS LIGTHS CAME ON AND MY BRAKES FAILED. I SCANNED THE COMPUTER USING AN OBD AND IT INDICATED FAILURE.
ON MOVING CAT, I KEEP GETTING INTERMITTENT BREAK ALARM WITH PUSH BACK OF BREAK PEDEL AND INABILITY TO APPLY BREAK. IT'S SCARY. I TOOK IT TO TOYOTA OF TAMPA BAY ON, AND THEY DIDN'T FIND ANY PROBLEM.
WHEN DRIVING MY 2006 PRIUS I AM UNABLE TO STOP PROPERLY. THE BRAKES GO ALL THE WAY DOWN BUT IT HESITATES TO STOP I GET A LOUD PEEPING AND THE ABS LIGHTS ARE COMING ON. I ALMOST HIT ANOTHER CAR WHILE DRIVING AND THE BRAKES ARE GOOD. I WAS TOLD THAT THERE WAS A WARRANTY ON THIS VEHICLE THAT DEALS WITH THE ABS SYSTEM. THE WARRANTY HAS EXPIRED AND TOYOTA IS PRICE GAUGING TO FIX IT, CAN SOMEONE LOOK INTO THIS BECAUSE IT IS A SAFETY CONCERN AND TOYOTA KNOWS ABOUT THIS ISSUE BUT WONT WORK WITH PEOPLE TO FIX IT?
FAILURE IF THE ABS BRAKE ACTUATOR AFTER 105,000 MILE IN FEBRUARY 2019. THE ACTUATOR WOULD RUN EVERY FEW SECONDS WHILE THE VEHICLE WAS ON CAUSING THE THE ROTORS AND BRAKE PADS AND TRIMS TO HEAT UP EXCESSIVELY. THIS IS A WELL KNOWN AND DOCUMENTED PROBLEM WITH GENERATION 2 PRIUS
WILL RANDOMLY REFUSE TO STOP ON DEMAND. VERY LOUD WHINING NOISE COMING FROM BRAKE ACTUATOR WHEN BRAKES ARE PRESSED. CANNOT DRIVE THIS CAR ANYMORE. OVER $1500 TO REPLACE!!
TOTAL LOSS OF BRAKES WHILE DRIVING ON HIGHWAY. PASSED THROUGH RED LIGHT NEAR MISS SITUATION. TOWED TO SHOP AND COST OF REPAIR EXCEEDS $2000 FOR THIS INVOLVED REPAIR AS THIS IS A COMPLICATED BRAKING SYSTEM. PART OF THE ABS SYSTEM CALLED THE ACCUMULATOR IS DEFECTIVE IN THESE CARS AND CAN RESULT IN SPONTANIOUS BRAKE FAILURE. YOU ARE ALWAYS SUPPOSED TO HAVE SOME BRAKING EVEN IF THE ASSISTED BRAKES MALFUNCTION. SUDDENLY, OUR CAR HAD NO BRAKES AT ALL. MY WIFE WAS DRIVING THE CAR WHEN THE BRAKES FAILED. SHE HAD ZERO BRAKES FROM THE PEDAL AND THE PEDDLE STYLE EMERGENCY-BRAKE HAD LOCKED UP AND OR WASNT ENOUGH TO STOP THE VEHICLE. SHE NEARLY HAD AN ACCIDENT. BRAKING SYSTEM SHOULD NOT GIVE OUT ON A VEHICLE THAT GETS VERY LITTLE WEAR TO THE BRAKES DUE TO THE EXTRA REGENERATIVE BRAKING SYSTEM. OUR BRAKE PADS AND SHOES HAVE LOTS OF LIFE STILL. THIS IS PURELY A DESIGN FLAW IN THE BRAKING SYSTEM AND I BELIEVE THESE VEHICLES ARE A HAZARD ON THE ROAD. I HAVE LOVED THE CAR UNTIL I EXPERIENCED THIS BRAKE FAILURE.
