My car breaks with out i almost hit the car in front of me, i could killed someone. This is very dangerous i took my car to a Toyota dealership they said the Extended warranty expired. They said upon inspection found code C1252, C1253, C1256 brake pump and actuator fault. Upon inspection found abs actuator accumualtor leak. Causing brake pedal to be hard and brake system malfunction. Toyota should had made a recall of this and not just a extended warranty that expires. I have 206,000 miles original owner they should me a lawsuit for this its very dangerous. I end paying $3000 of my own money to fix it, i should get reimburse for my money.
ABS, Break and traction control lights from dashboard lit on and breaks were difficult to operate during driving, able to drive back home safely. Find out that ABS (brake booster and brake booster pump assemblies which are consider safety items), are defective and can cause accidents. When calling Toyota Customer Experience Center, they decline to honor customer support program ZJB due to my car is exceeding by 5k miles the additional limited warranty. Now I will have to pay out of pocket on known safety defective part, this should be a recall and not wait to an accident to happen.
My teenage daughter was driving and almost had an accident because the brakes failed. No warning lights came on until the brakes failed. I am learning now that it is a brake booster pump that Toyota knows about it as they had issued an extended warranty on the same thing that expired last year. Toyota confirmed that my Pruis was included in the customer service program but it has now expired.
While coming to a stop there was a loss of braking power and feel. Due to the unexpected change in braking characteristics this nearly caused me to collide with the vehicle in front of me. Noticed the traction control, ABS and Brake light on dash illuminated. My local Toyota dealership has diagnosed the repair as a repair involving the brake booster master cylinder and pump assembly.
On June 11, 2023, my Toyota Prius brakes failed while I was driving! The vehicle was towed to the Toyota dealership on June 12, 2023 and determined the car needed brake booster assembly with master cylinder, based on codes presented at diagnostic. Quoted repair cost of $3,544.99+tax. I am second owner of this vehicle, which was purchased December 2020 from the same dealership. I was never notified about this pending issue from Toyota North America or from the dealer. I contacted Toyota North America on June 13, 2023 and was denied repair because Consumer Support Program 20TE07 expired May 2022. This Consumer Program should have been a recall. Brake failure is a major safety issue.

The Brake Actuator and Brake Accumulator were covered under a customer support issue until 5/18/22 On our car they are charging me $2600 to fix this issue. The car was at Toyota years earlier for a recall but Toyota never told us about this issue. That is not fair in my opinion. And now we are being charged $2600 to fix this issue Best [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
The Brake Actuator and Accumulator on the car have failed Toyota had a customer support issue on these parts and fixed them for free BUT it expired 5/18/22 No Toyota dealer told me about this issue and I received no warnings Now the 2012 Prius with 78,000 miles has this issue and Toyota wants $2600 to fix
The contact owns a 2012 Toyota Prius. The contact stated while driving 50 MPH and depressing the brake pedal, the vehicle failed to respond. The vehicle responded after depressing the brake pedal several times, and came into a complete stop. The ABS and anti-skid warning light were illuminated, and the message "Brake" was displayed. The vehicle was taken to an unknown location, where it was diagnosed that the rear passenger brake sensor needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken to an independent mechanic, where it was diagnosed that the pump actuator needed to be replaced. The vehicle was not repaired. The mechanic referred the contact to the manufacturer. There was no further information provided. The manufacturer was contacted and informed the contact that the vehicle could not be repaired under an unknown Technical Service Bulletin Number as it had exceeded the mileage and year required. The failure mileage was 165,000.
Driving on Interstate and suddenly traction control light, brake Light, and ABS light came on. After this the brakes were not as affective at stopping the vehicle and felt sluggish. Found a lot of reports online about similar issue and even some when the vehicle brakes failed. My brakes allowed me to get home without incident.
Our 2012 Toyota Prius experienced brake failure due to the Accuator and Accumulator. I contacted Toyota Corporate office, which advised it is a known problem and had a customer support program that expired last year. The Toyota rep advised me to not drive the vehicle because of the brake failure and opened a ticket advising it is a known issue. After researching online, it is a very common issue. https://www.aboutautomobile.com/Consumer-Complaint/2010/Toyota/Prius/Brake
Suspected Brake Booster failure. We have been experiencing our brake booster running several times a minute and something felt off. In December, we took it to the dealership who said they "were unable to replicate the issue". We found that odd since we experience the issue every few minutes, but we believed them when they said that there was nothing wrong with our brakes. Yesterday, about one month later, we were driving on a busy street when our brakes appeared to fail. We couldn't make the car stop, three dashboard lights came on (the ABS and two others) and eventually we realized the brakes had to be pressed really hard to get the car to stop. We avoided an accident, pulled into a parking lot, turned off the car, checked the brake fluid (the brake fluid was fine), restarted the car and the lights still remained and the brakes continued to not compress easily. We called our Toyota dealer who said that there is no recall on our Brake Booster and that this is not a known issue, and yet there are hundreds of readily available accounts of 2012 prius owners who experience the same fail.
Toyota Program ZJB, internal malfunctions of the brake booster assemblies. A known failure of the brake booster than Toyota did extend the warranty on for 10 years BUT would not honor the warranty unless specific diagnostic codes appeared on the vehicle. My issue is that all of the symptoms of the failure occurred on my vehicle (pump constantly running, varying hydraulic pressure resulting in pulsing brake stops, soft brake pedal) but the warranty would not be honored because the diagnostic did not manifest itself. Had technicians tell me that it definitely was this booster failure, but Toyota would not pay for it unless the diagnostic came up. I am now left with a vehicle that has a failed brake system and no monetary support from Toyota. Quoted $2500 to $3000 to repair. Not safe to drive in my opinion with a known failure that I am having trouble getting funding to repair. Contacted Toyota customer support and they reiterated that they would not pay for the repair without the diagnostic occurring and now their extended warranty expired August 31, 2021. Inspection available upon request Safety issue as braking is inconsistent and not predictable Problem was identified by Toyota dealer service department No diagnostic alarms - which is the only symptom not present
The Brake Booster or Actuator is failing, without any indication or warning lights on the dash alarming us to the problem. The car has been making weird sounds, but after being inspected, this, according to the Authorized Toyota Dealer, on December 22, 2022, is a life-threatening and very dangerous malfunction to myself and others around me when driving. This is the first hybrid car we have owned, and we thought the noises we had been hearing for a couple years was normal, because there were no warning lights coming on to tell us otherwise. The dealer did not want us to drive the car any further due to the danger of the problem. We asked the dealer to repair the problem without charge, but that request was denied by the Toyota Brand Engagement Center (Case 221222000587). The dealer is currently repairing the malfunction at a cost of approximately $2650 plus tax). We are highly disappointed with Toyota not repairing this known problem under a dealer recall.
The brakes on my 2012 Toyota Prius failed suddenly with little warning after starting the car, and when I began driving off in a busy Walmart parking. I was startled when I felt that the brakes did not seem to work, nearly causing me to collide with the car in front of me. I had to quickly depress the brake pedal to bring the car to a stop. The normal braking power was greatly reduced when I depressed the brake pedal, and I had to use more force to bring the vehicle to a stop. Only when I looked down did I see that some of the dashboard lights relating to the brake system stayed lit and not turn off like they normally do. These lights appear to be brake warning, ABS warning, and anti-skidding lights. The brake problem has been inspected and confirmed by both an independent service center as well as the Toyota dealer. The failed brake component was diagnosed as an abnormal leak in the accumulator, and the brake booster with master cylinder assembly requiring replacement, with the code #c1391. After having done some research, it appears that this exact brake problem seems to be afflicting many such generation Toyota Prius vehicles, and the manufacturer Toyota was aware of this problem existing in such vehicles.
The car has been diagnosed by a Toyota dealership as having an internal leak in the Brake Booster and Accumulator, both are part of the brake system. Repair estimate of $3800 00 dlls. Currently i have 3 check lights on, Brake, ABS and Traction control. All controlled by the same module
My prius got ABS, Brake, Traction light on when I was on traffic in the highway. Car lost brake power. Regenerative brake does not. It takes longer to stop the car. TOYOTA NEEDS TO FIX THIS. THE ABS MODULE IS GONNA FAIL AT SOME POINT. Dealership asks $5000 to fix. C1391
At 106K miles and after 10 years and 8 months in service (new vehicle bought in March 2012) Brake booster internal leak, code c1391. Brake light, ABS light and VSC light stay on. Can not drive it as the brake booster internal leak is making the brakes spongy and slow in response. Talked to Toyota and they said it is out of warranty and the deal is estimating $2000 plus for the repair. Miles on my cars 106K are way less than 150,000 allowed by Program Service bulletin ZJB (attached) but Toyota is denying repair coverage as the vehicle life is eight months more than 10 year limit since first use. Did not drive it much within the last two years because of working from home due to covid 19. Had it been driven more frequently the brake system failure would have happened way earlier as the internal leak (possible fatigue failure causing leak) should be more related to driven miles and brake system cycling of pressurizing and depressurizing than just being parked on the drive way. Would request if NHTSA could extend the duration of ZJB bulletin considering the fact that many drivers did not drive that much in the last two years due to working from home and this internal leakage failure can be related to fatigue loading of the hydraulic components and the number of fatigue cycle are directly proportional to the driven miles and not the life of the vehicle. Thanks
I have a 2012 Toyota Prius that the Toyota dealership has confirmed that I have a failed ABS actuator and is displaying the correct repair codes for the service bulletin but they refusing to cover any of the costs to replace the ABS actuator and boost pump. Since the failure of the ABS actuator I have had 2 close calls where I needed to stop fast and my tires locked up, I lost control of the car and spun out but luckily I did not hit anything. The brake, ABS, and 2 other warning lights have come on and off intermittently on the dashboard of my 2012 Toyota Prius. I summited a good faith request to the repair my Toyota Prius ABS actuator at Toyota of Anaheim on 10/28/2022 and due to it being 20 days past the 10 year limit and slightly over the 150,000 mile limit at 158,000 they say that I'm 100% responsible for the repair costs of $3,231.78. This proven design flaw is not my fault, it did not occur under normal wear and tear and the brake ABS actuator and boost pump should last much longer than it did. Now I'm faced with paying a huge bill for the repair or pick up my Prius from the dealership and drive it home with a defective ABS actuator. This is another example that Toyota is placing profit ahead of safety.
