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.

Failure of ABS actuator. I received notification of a " warranty enhancement " program that extended the warranty for my vehicle on the brake actuator assembly. The extension portion of the warranty for my vehicle expired on December 31, 2017. I purchased the car new in 2006 and have faithfully had it serviced by the Toyota dealership every 5000 miles. Toward the end of 2017 I noticed the car making some noises after I parked it in the garage. I attributed it to the noise that the car often made when first turned off. I had the car in for service at the Toyota dealer in Oct and Nov 2017 and again in Jan 2018 and no problem was identified with the actuator. The noise continued and became more noticeable so when I took the car in for its routine service in March 2018 I asked them to check what was causing the noise. When I went to pickup the car they told me they did not hear the noise. When I got back into the car I immediately heard the noise and accompanied them back to the car to hear the noise. The mechanic took the car back to the shop and when he finished I was told it was the brake actuator assembly going bad and was quoted $2700 to have it replaced. I was advised that I would know know when it failed completely when several of the warning lights illuminated. Yesterday while driving 55mph on a 4 lane highway all of the related warning lights came on. Fortunately the brakes still worked and I was able to make it home safely. After exploring the internet I found this is a fairly common dangerous failure and thought it was interesting that Toyota has stopped providing replacement when this part fails especially as they are aware of the issue.

While driving, the brakes just quit working properly. I had very little stopping power. A lot of lights on the dash came on vsc, ABS, skid, etc... after researching, I see this was covered under an extended warranty period up until December 31, 2017. Toyota is not covering fix and told me to fix car for $3000 or park it, it is not safe to drive. This is a safety issue and I almost got into an accident. Please help. Never received a letter from Toyota even talking about the recall.

My car (06 Toyota Prius) had hit a pothole while on my way to church on 11/16/17. There was a lot of traffic and though I was far behind the person in front of me, my brake did not stop and my car went under the car in front of me. The vehicle was going maybe 5-10 mph as we inched up to the light. Lots of traffic, I was double and triple checking to see my foot on the brake and it was but car would not stop, in fact it felt like it revved up.it was terrifying as I saw my car plow into another when there was nothing I could do. I know the 2010 models were recalled for this but it happened to me on my 2006 Prius. No recall but a warrant enhancement notification was sent to my relative who had a 2007 but I never received it. It is all about the brakes and the not stopping properly. Toyota also did a weird buy back thing and wanted my car. I think it is because they wanted to hide the problem instead of having a recall. I have never had a company try to buy back my car. Toyota is at fault and I want to make sure no one else is killed or hurt by this. It also shows up in the technical service bulletin but again, not a recall but it needs to be recalled! my car had about 65K on it.

Was going to church thurs evening and fast driver ahead of me in busy intersection. Stayed far away from her but when she slammed on her brakes, I hit mine as well knowing I had plenty of time to stop but the brakes did not work, even though I pumped them and then slammed them on again. (I have had other people tell me they have had the same problem with their O6 Prius'. I ended up hitting her car and my car was totaled even though we were not going fast (red light up ahead). I am going to see if my acceleration was fixed because truly I could not stop the car. In fact a man who helped at the scene told me to 'take foot off the brake, the car will not go anywhere' but I was so scared that if I did the car would move again.

I was in a 2006 Toyota Prius car accident on the freeway when the steering wheel started jerking (to the point of no control), the brakes stopped working and the car kept accelerating. Car lost control. Car was totaled, two witnesses and a police report. I was sent the emergency room. No responsibility was assumed by Toyota, which completed their "inspection" on March 9th, 2012. Then eight months later on November 14, 2012 they come out with two recalls: A steering recall & an engine and engine cooling, hybrid propulsion system recall, probably as part of what they saw happened to me. I was never notified after about these recalls that my car potentially could've been defective from and part of.

Dry, clear day. Driving on a city street.red lightwith bus in front of me and a car next to me. Speed limit was 45mph. I applied the brakes and nothing happened.. it felt as though the car accelerated slightly.I tried to apply the emergency brake and the one on the dash.again to no effect. I managed to avoid the bus by driving on the median strip and missed a large palm tree. The motor stopped and I coasted about 150 feet. This is the second time I have had a problem with the brakes. The first time the brake pedal did not move at all and the engine accelerated. Managed to avoid all vehicles. Took the car to Toyota and was told that the Prius had a little glitch in all of them and my car is ok now. Did not want to check the computer or any part of my car.obviously, there is a defect in the computer system hit a heavy information traffic sign on a steel pole.

When I driving on a decline and hit uneven ground or a pot hole, while braking, the car will lurch forward and the braking is suspended for a second. This is a recurring event and can be easily replicated with high probability. I have listed the most recent time this error has happened.

While driving into a parking lot, the brake and the exclamation lights came on followed by a continuous beep. The brakes suddenly failed and I had to apply excessive force with my foot in order to stop the car. I turned off the car and went to do some errands, like 10 minutes later, I turned on the car. The brake and exclamation lights were off and the car was able to brake normally. The next day, while returning home from college, after a 25 minute drive in the highway I went through a secondary road, the same problem showed again, lights and no braking power without any prior symptoms. Once I applied excessive force to stop the car the wheels locked. I pulled the car to the side of the road, turn it off and the on and the car continued to drive normally. I stopped using the car after this. Probably a brake actuator is defective but there were no symptoms prior this problem, the car just suddenly does'nt have brake power.

The combination meter on my 2006 Prius has an intermittent electrical short. This results in the dashboard lights going out while the car is moving. This problem with the electrical system on the Prius can result in the brakes on the car failing. In addition the car often continues to stay on after we turn it off. This is also a safety hazard. Toyota has refused our request to replace the defective combination meter, even though this is a widespread problem.
