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
I have a 2006 and 2012 Toyota Prius. Both show a malfunction with the ABS actuator hydro boost pump. This appears to be a common problem with the Toyota Prius' as shown on you tube and the Toyota Prius forum. Dash lights lights include brake light, ABS light, trac. Toyota dealer says they are not aware of the problem.
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.
The brake actuator started making frequent noise. The ABS warning light and beeps immediately after starting the car. The clanking or humming noise during braking
The brake actuator and accumulator have failed! our understand is that this is the part that stores power for breaking when it's operating under battery power vs. The engine. Researching on the internet and taking it to the dealership both revealed that this is a very common problem. If you do an internet search you will find abundant complaints on this issue. Apparently, Toyota had a "silent recall" on the repair, but that ended 12/31/17. Now they no longer cover the $2700 cost of the repair. There are several internet reports of people getting into accidents due to the failure. The car drives fine, it just doesn't stop well at all, intermittently (when under battery operation vs. Powered by engine, and we would estimate the breaking function when under battery operation to currently be at 20% of normal.

Car has no brake when first start up. Put car in drive after start up and would have no brake. Almost hit parents and kids in the morning at school or even in grocery parking lot.
As I was reversing and my foot was on the gas pedal a loud beep came on, all of the dashboard warning lights lit up including the brake light. I checked to see if my parking brake was on and it was not. I put the car on park and turned the car off and on. My car worked I drove a few minutes and as I was approaching the freeway I luckily came to a stop on a red light. Suddenly the same loud beep, warning lights, and break light came on and this time because my foot was on the brake pedal I felt the brake extremely hard/stiff. Because I was at a red light I quickly put my car on park turned the car off and then on again and made a right turn to avoid going on the freeway. I decided to carefully drive to a family member's house close by going no more than 25 mph with my emergency lights on I did not want to risk my brakes stiffening up and failing but I was in a congested area with no parking. I was fortunate enough not to get on the freeway and I was fortunate enough that this failure happened on occasions where I was either going very slow or already stopped. I don't know what could happen if I had to come to a stop and could not because my brakes were stiff. Toyota will not cover this manufacturers ABS actuator defect that they know about because the deadline was Dec. 2017. This is dangerous and can lead to accidents and even death.
My vehicle has a defective ABS actuator, a part previously under recall by the manufacturer-Toyota. (2006 Toyota Prius ABS part, actuator complete assembly, id 44510-47050) warning lights: Master warning ABS brake system: Codes: P0571, C1256, C1391. This defective braking component makes my vehicle extremely unsafe to drive along with thousands of other Toyota vehicles on the road today. This ABS actuator can fail at any time and at any speed. Toyota previously launched an extended warranty campaign for this same part on a percentage of vehicles, but purposefully excluded thousands of vulnerable drivers from getting necessary repairs. Toyota has refused to replace this part in thousands of unsafe vehicles even while they acknowledge it was manufactured with known defects. This part is worth nearly the trade-in amount of my vehicle. Toyota is deliberately keeping unsafe vehicles on the road, with a known issue.
Luckily, I was waiting at a stop light when I heard a click/tsst sound. I felt my break pedal push upwards. I took my foot off of the pedal and realize that my braking power was very minimal. The car was only coasting to a stop regardless of the pressure applying and I had to fight to apply pressure to the brake pedal, at this time the car was stationary. I then creeped into the turn lane, giving my car about 7-10mph. When I applied my brakes, my car was not slowing down, I then slammed my breaks and my car speed up and slammed into a gas station.
The ABS actuator runs continuously trying to keep the system running. My mechanic says its just a matter of time before it fails, the cost is $2900 to fix, Toyota, S warranty enhancement zg-1 expired Dec 2017 and will not replace the ABS actuator.
Brake actuator failed when car was backing up in a parking lot; car made jerking action and stopped on its own; all warning lights lit; warning to take it for service immediately - which was done after consultation with the dealer (driven there).
I was driving normally and suddenly a continuos beep was there, I tried to stop a no brakes.I was able to steer my car to a safe place.then used a toll service and took it to my Toyota dealer.in a short time they told me they told me the computerized brake system was defective and the job will cost me $2250 I can not afford. I tolled the car back to my house.later I found that there had been a recall from Toyota.I was never notified although I took my car there for regular checkups. Note: My car was in motion and previous to incident I had descended a steep hill. I consider myself lucky on that date, three minutes earlier I would have been in great distress trying to stop my Toyota Prius.
The ABS actuator is failing to prime causing the anti-lock brakes to slip and the brakes not to engage. This has happened multiple times while both stationary and driving. I see that Toyota had extended warranty related to this issue however that expired 12/31/2017. My issue started in January of 2018. I have attached a copy of the warranty enhancement for reference.
My brakes failed 4/3/18 while I was in traffic. I was driving on a city street during rush hour. The car in front of me braked in traffic and I had plenty of brake distance but as my car slowed almost to a complete stop it suddenly felt as if the engine revved and propelled the car forward even though the brake was fully engaged. The only thing that stopped the car was that it ran into the car in front of me causing damage to both cars. I told the two officers that arrived about the problem with my brakes but they ignored me and issued a $165 ticket for "following too closely". the accident became a lawsuit and a rep from my insurance contacted me for details. I also told her about the problem with the brakes and once again was ignored. This past Saturday (4/14/18 about 2 weeks after the first brake failure) I decided to go to the grocery store. After shopping I got into my car, hit the power button and put the car into reverse, my intent being to leave my parking space. I kept my foot on the brake since I saw a car approaching from my right in the parking lot. My car was stationary, but I had my foot on the brake and my car started to move in reverse, even though I had the brake pedal fully depressed. It just drove itself, in reverse, out into oncoming parking lot traffic. This time I was better prepared and since the car was moving from a complete stop, it wasn't going very fast so I pumped the brake pedal and that seemed to "reset" it and the brakes came back. This time I was able to stop the car before colliding with anyone. I have always loved this car but now I no longer feel safe driving it and unfortunately, I cannot afford to buy a new car. The stress alone is causing me to lose sleep and Focus throughout my day. Every time I have to get behind the wheel and the worry that I may end up hurting someone else. This is a serious safety hazard.
Prius making buzzing sound every 15-20 seconds dues to faulty ABS actuator pump while driving and when the car turned off. That means it is leaking breaking system pressure. Now it's getting worse as ABS pressure does not stay and car rolls when switching from park to reverse or drive mode. Have to keep applying breaks for car to stop. The rolling occurs good 3 to 4 seconds and that's enough to cover 3 feet or so. It's dangerous when reversing from park with slope surface.
