2012 Toyota Prius

The brake master cylinder/accumulator has failed causing multiple codes as well as dash lights for the brake and abs systems. I took the vehicle to the local Toyota dealership after reading about this problem in all other models of the Prius. I have just purchased the vehicle. They covered this issue with a free warranty replacement up until August of 2021. They had extended the warranty with restrictions until this next year. Reading about other models of the same car, the warranty still covers regardless of mileage. It's the identical part as other models that are still being covered. This is a $3000 dollar repair made in some vehicles for the identical part, but not in others. This is terrible customer service for an unsafe issue by Toyota. This issue does effect the braking in the vehicle and it is unsafe to drive. The regenerative braking also no longer is functioning changing the entire handling and characteristics of the vehicle.

Vehicle has issue with brake booster and accumulator, making it dangerous to drive on the road as brakes would intermittently go out not allowing me to stop. Toyota Corporate had agreed to fix the vehicle originally based on good faith and acknowledgement of the defect under their "Customer Support Program" yet coerced me to go to the local dealership to get the repair, and now disclaims responsibility to cover the repair/parts costs. Toyota Corporate did call the dealer to authorize the repair on 12/14, but since then, have not paid for any of the repairs so my vehicle is being held hostage at the dealership.

I have a ABS alarm on my car. Toyota ABS C1391 (1/1) Current Abnormal Leak of ACC Press I tried to Talk to the Toyota I left a message with the service writer At Avondale Toyota In Arizona and left a message about my car problem They never returned a call to me! I have bought 4 new cars from Avondale Toyota. You would think they should return my call to talk about my cars brake problems I haven't received any return calls

Toyota did not inform us about a half recall on our family's Prius car. My wife driving yesterday with kids Christmas shopping and the brake pedal stopped working. She was able to thankfully to have space to let car slow down and pull off to side of road. People with a Toyota Prius need to know the brake pedal could stop working at any moment. The Toyota dealership says the repair is $2900 and they will not cover it. They advised I call Toyota so I did and spoke to 3 people advised and they said they would not. The half recall states online, which I dug and found after the dealership advisor told me about it, states that cars up until 8/31/2021 with unlimited milage are covered. After, then its 10 years from purchase and drops from unlimited milage to 150K. We are a few months from Sept and they would not make an exception and do the right thing. The cars is past the 150K milage BARELY, but still under 10 years. If the breaks had gone out in August 31st and a major accident happened would Toyota been liable? HAs this happened and people don't know? It's not right, not ethical, we were not informed of this at any point or even the last time I took the car into the dealership. The idea that others could have this happen to them or even get hurt out there is insane to imagine as a possibility actually a reality as it happened to us. Toyota headquarters brand representative (Monica supervisor) on phone told me that if my wife had the break pedal and system go out in August and died Toyota would have covered it. I almost dropped the phone. Others need to know about this. Do you know anyone with a Toyota Prius? or a Toyota? Please tell them the brake pedal could stop working at any moment and cause an accident. Please help us and together help others know about this. Toyota should have done the right thing, but they didn't. Toyota needs to alert others of this before someone gets hurt. The National Safety board needs to force to a full recall to REPLACE THEM

ABS/Brake Actuators on these cars are faulty! Not able to apply adequate pressure on the brakes to stop the car confidently. Brake actuator hissing notating that pressure is being lost. Brakes feel like they are skipping, and also making a loud "quack/screeching" noise. Brakes were inspected on my vehicle, and the pads had over 60% life left, and no damage to the rotots, so its the brake actuator at fault. A very common issue on 3rd generation prius models, and a $3000+ repair through toyota. Customer support program ZJB issued. Its not a recall, but instead an "extended warranty". Toyota will not fix the problem without dash warning lights on, so my car is just waiting to break down or cause an accident. I worry about my life and the brakes failing at some point. Ive taken it to two different mechanics and they both noted its a well known problem that toyota is trying not to pay out for.

I write to report that I asked for help at TOYOTA on the repair of the brake booster pump program. On August 19th, 2021 I took my Toyota Prius 2012 to my nearest dealer, in this case, Toyota of Homestead in Florida, US (I have a screen capture of the appointment); because the brake pump was pumping continuedly every 15 seconds regardless of the vehicle was in motion or stop parked; also the breaking felt like spongy and hesitant. I explained that to the Toyota dealer employee and he told me that the pump running every 15 seconds is not normal and agree that something was not right with my car's brake, but if there is not a MIL light ON, they can not replace my brake booster under the Toyota Program, and I have to pay $170.-first to "scan" the vehicle and make a diagnostic, well I told him that was too much money just to scan the vehicle since there was no light on in the dash the Toyota employee told me I will need to pay for the full brake pump replacement. That was unfair because the Toyota employee agree that definitely the brake was bad, but can not do anything. Took my car home and a few days later September 2nd, the brake lights came on. Well, my wife uses this car daily to transport our kids to school and to do the shopping necessary for food and supplies, and definitely, the cars do NOT break AS IT SHOULD. Toyota employee told me the repair will cost between $3000.- to $4000.-, I took the car to the Dealer when was covered under the Customer Support Program, but the light on the dash should NOT be the main factor to determine that the brake booster needs to be replaced. To be fair TOYOTA should recall all those vehicles. The Toyota dealer employee witness that there was a problem with the pump, and anybody with common sense that know this cars should immediately notice that the sound of the pump going on every 15 seconds is NOT NORMAL. This is my second Prius (My first one was a Toyota Prius C 2014) and I detect almost immediately with something is WRONG.

Brake Booster assembly has failed on my car preventing the regenerative braking to function normally and it could potentially lead to the brakes failing all together. Upon further research it seems to be a common issues with these vehicles and Toyota has a "Customer Support Program" under the code "ZJB" that will replace the faulty brake booster assembly. My car is still technically covered under the service bulletin that Toyota sent out but when I called several dealers and Toyota corporate, they notified me that my car was ineligible due to mileage. I was quoted over $3,000 at various dealers to replace the part to what amounts to a basically very expensive brake job. I am concerned for my safety in terms of the brakes failing while driving. This is my only vehicle and I have started to resort to driving on the city streets as opposed to the freeway.

The brake, abs, and stability control light come on and the brakes require more pressure to function. The problem is intermittent, but has been happening more often and for longer. The rotors, pads, and brake fluid were looked at within the last month and have no issues. I am getting a code C1391 Abnormal Leak in the Accumulator. The symptoms, as well as my car year and make match this recall, but I was never informed of this recall and there are no open recalls associated with my VIN. https://toyotatalk.com/wp-content/uploads/2019/03/ZJB-Phase-2-.pdf?fbclid=IwAR1I91f2ohQk73kYnbBYOlOi-yYlpgVNQ0leI3N8uWbg7V4IMKgULdG7F10

The brakes felt very spongy and the car was having a difficult time coming to a complete stop. The ABS, brake, and stability control lights turned on at the same time. Also, a whirring noise close to the passenger side started happening every 2-3 seconds. After some research I later learned that the noise is most probably coming from a brake pump assembly that has failed and is not able to keep pressure. The car is currently parked since I don’t feel safe to drive it. I contacted a local dealer to see if this part can be changed for free since this is not normal wear and is unsafe. I also learned in online Prius owner forums that there is a large group of Toyota Prius owners with the exact same issue.
