Brake acutator failed again after 1 year of use. The brakes failed on this car a year and a half ago, resulting in pedal to the floor and many warning lights going off. Dealer and toyota replaced brake actuator through hidden warranty I had to fight for them to pay. Drove car out of dealership, and it made a squeaky sound coming from under hood, not from brake pads. Turned car around and they took it back. Said they bled air out of brakes. Squawk came back and on next oil change, told them. "no codes, so don't worry about it." was the diagnosis. Squawk continued over the next year and a half, and the same reply from service advisors. "no codes, no worry - maybe we need another brake bleed, but not mandatory." 2 more oil changes at dealer, and the last time, I mentioned the squawk again and the brake bleed to a new advisor and new ownership. "needs a brake actuator - and we will not pay for it this time." I reported the problem to them many times during the one year warranty of the actuator. Now they want me to spend over $2500 on a new actuator because I was a few months out of warranty on new part. Toyota also refused to pay. The brake actuator and accumulator have failed on this car and our other prius a total of 4 times now. This is obviously a major safety issue, and I'm really surprised you are not working with them on a mandatory service campaign. The service manager said they see this issue over and over again, and that toyota did a full redesign of the braking system on the new 2017 model year. Brakes are the most important system on a car. Without them, an accident almost always follows. Please initiate a recall on this as soon as you can. Thank you.

I own a 2005 prius and have 3 unintended acceleration incidents in 5 years, two separate drivers. City driving at 35 MPH. Pedal did not stick, it was sucked to the floor we turned of engine before speed got to 50mph. No accident or injury, note this: each time I asked the dealer repair shop about it, they dismissed it as floor mats and "could not reproduce it ". Interestingly, the repair request did not show up on dealers action list (2 different dealers) even though every time I asked about a squeak or rattle did show up on the records.. Did toyota give instructions to dealers on how to downplay it and not record the complaint?

On 11/5/09 in mid-afternoon I was driving my 2005 prius north on calvert st. In baltimore city, just above saratoga st., at about 25 MPH when the traffic in front of me slowed. At the time I was speaking to my boss on my verizon cell phone using my bluetooth headset. I applied my brakes and the car was braking as usual slowing down normally until about 10 MPH, or so, at which point I felt the car bounce very slightly and gently as if there was a small gradual dip and rise in the roadway surface. My foot was still applying light pressure on the brake pedal as I intended to come to a near crawl as I neared the car in front of me, but after the slight bump the brake pedal gradually went to the floor and my car proceeded without any braking in effect. After the pedal was depressed to a point near the floor I pumped the brake pedal once and press on it as hard as possible. At this point the right rear wheel brake applied and the rr tire squealed as it appears it was the only one braking. I continued pressing until the car came to a stop at which point I notice that several of the instrument panel lights were now on, including the ones for the brake, the ABS, and vsc. I then continued driving slowly home, about 2 mi., because it appeared that only the rr brake was working and that there was not power assist with the braking. When I got home I turned the car off and then back on to see if the problem persisted, and upon restart the brakes appeared to work properly and some or perhaps all of the warning lights were off. I took the car to bill kidd toyota in timonium, md on 11/9/09 and they reported that scan code c1357 was present. They reportedly contacted toyota tech assistance who instructed them to clear the scan codes and perform linear solenoid calibration. They road tested the car and said it was ok to drive. My boss was on the phone with me during the entire incident and hear the rr tire squealing and we discuss what was going on. I am a mechanical engineer.
