Brakes Failed problems of the 2006 Toyota Prius

The brake booster is making lots of chirping noise when the brake pedal is depressed. While I am not getting any visual indicators of failure at this moment I believe (due to my own research) that when I do there is a high chance of me getting into a car accident. I have read on Priuschat. Com that several people had brake failure due to the faulty pump which caused a car wreck. This is a dangerous predicament to be in and Toyota should extend their warranty to cover the faulty equipment they have installed on these vehicles before someone gets seriously hurt or dies.

The brake actuator has failed and Toyota wants $3000 to repair it and I see hundreds of people with the same issue. I only have 137000 on the vehicle.

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).

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.

Owner began noticing braking problem in November 2017. Brake pedal would go to floor with minimal braking. Problem continued to get worse. Owner took vehicle to Toyota dealership after holiday period on 02/09/18 for diagnostics. Toyota advised owner of failure of the brake actuator assembly, $2500. 00 repair, and dangerous to drive vehicle without repair performed. Toyota was aware of this serious brake defect in their vehicles and issued a warranty enhancement program zg1 to correct at no cost to owners. The enhancement program ended 31 December, 2017. My vehicle was diagnosed with exact brake failure problem 2 months later on 09 February, 2018. Toyota refuses to correct this catastrophic brake failure. Request NHTSA to issue new direction for Toyota to correct this catastrophic brake failure for Prius vehicles beyond the 31 December, 2017 date.

We are going to be injured or die due to failure of the brake actuator assembly. This exact failure was covered under a warranty enhancement program zg1 which has expired. We cannot afford this repair exceeding $2500. Toyota is non responsive. We are seniors with no hope of resolution. Please intervene. We do not want to die from this brake failure. Thank you and may god bless us all.

Brake actuator - zg1 -Toyota had extended warranty for defective brake actuators up to 150,000 miles or December 31, 2017 as part of their zg1 warranty extension program for the 2006-2009 Toyota Prius. Many catastrophic brake failures are still occurring as a result of this defective part for vehicles as young as 6 years old that are now outside this warranty. The failure may result is accidental injury or death. This defect now effects my personnel vehicle.

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.

The contact owns a 2006 Toyota Prius. The contact stated that the brakes failed, causing the contact to crash into another vehicle. The contact was reported injured however a police report was not filed of the incident. The contact had the vehicle towed to a repair shop for inspection but the cause of the failure was unknown. The manufacturer was notified but advised the contact to speak with his insurance company. The failure mileage was 122,000.

"!", abs, and vsc lights come on and brakes stop working - while driving. Must coast to side of road, turn off vehicle, and restart. Then brakes work for a while until problem recurs. Replaced brake stroke sensor. Fixed problem for 17 months - 20,000 miles. Again, brakes fail while driving. Getting code dtc 1247 - fault in stroke sensor. Told part is out of warranty and must be replaced again. Vehicle shouldn't have a part that fails every 20,000 miles resulting in complete loss of braking while driving.

Brakes failed temporarily and momentarily when braking over potholes while approaching an interstate on-ramp. This is not at all the first time this happened. When braking while going over railroad tracks, especially double sets of tracks, it has been common that it would feel as if I was sailing over the tracks -- definitely not slowing down (even though I had my foot on the brakes) but maybe even speeding up. That too was the feeling I had, albeit momentarily, last week when I was braking over potholes.

Gov from:[xxx] subject:2006 Prius brakes comments: I have a 2006 Prius and have had intermittent brake problems(I bought the car new from the Toyota dealer in 2007). The brakes do not always engage immediately when pressing the brake pedal. It feels as if the brakes are slipping before actually stopping the car. In light of the recent Toyota brake recalls, I now have concerns that my car may also have brakes that may fail. [xxx].

On 1/30/2010 at or about 9:00am. My daughter's 2005 Toyota Prius brakes failed enroute to mammouth. No snow or rain was on roadway. We have been unable to reach he since, but our sending this complaint to document this incident in the event an accident occurs.

I'm filing this as it may relate to your current investigation of the Toyota Prius braking system. I have a 2006 Toyota Prius with electronic stability control (esc). I've noticed that, at times when the esc is activated by a bumpy/slippery road, that attempting to activate the brakes (via the pedal) at that moment (shortly after the esc has activated, per the dashboard light) will sometimes "fail". The "failure" being that the brake pedal will depress to the floor (often with a 'clunk' noise - maybe the brake pedal hitting the floor?) without activating the brakes. I've found, every time, that releasing and re-depressing the pedal activates the brakes without fail. This has happened on numerous occasions so the "approximate incident date" I've entered is a best guess of the most recent occurrence.

It was raining heavily with poor visibility. I drove about 15 mile mph on a one-lane road with no traffic lights or signals. I saw a car ahead of me and slow down even more to about 10 miles mpg and kept distance. When the car stopped suddenly about 30 feet away, I engaged the brake. However to my dismay, the car kept rolling. When I realized that I shout in panic "please stop, stop!" for about 8 second I hopelessly watched my car slowly ran into the car in front of me at a speed about 5 miles mph. Because it was such a slow speed, my car's front bumper was almost intact but my hood was damaged by the rear bumper of the SUV. I had an estimated damage about $1100. I thought it was because of the slippery road. After searching internet, I realized that the slow speed brake failures are well-documented by many drivers. Other people's experience were very similar to what I experienced. Therefore I would like to register my complaint.

I own a 2006 Prius which I was driving at low speed in a left turn behind a freight truck. As I approached the rear of the truck I applied the brake. The brake pedal depressed in the normal fashion, however, there was no response from the vehicle -- it continued to move forward with no change in speed. Immediately aware that something was wrong, I quickly and methodically 1) visually confirmed that my foot was on the brake and that there was nothing obstructing the pedal, 2) checked my peripheral vision to confirm that I was indeed moving forward rather than the truck ahead of me moving backward and 3) placed both feet on the brake at full force and held firm while quickly visually checking that my feet were in fact on the brake. I also checked the dashboard to confirm that the car was on and in a normal "drive" gear. At last, it was too late and I smashed into the back of the truck, still with both feet on the brake. The truck driver emerged from the cab, a bit shaken but not hurt. His truck was not harmed as I hit a heavy metal frame that was attached to the back of the truck. The hood of my car was dented and scraped. In response, I removed the car from traffic, cancelled the meeting I was on the way to and slowly drove a very short distance to my employer's parking lot and parked the car. I called the nearest Toyota dealer, explained that the brakes failed and, at the dealers recommendation, called their towing service to take the car to their service department. The service department examined the brakes and "found nothing wrong with the vehicle 'at this time. '" their diagnostic testing could not determine the cause. And, since they were unable to duplicate the situation, they are taking no responsibility for the brake failure. The car is still at the dealer as I do not feel it is safe to drive.

2006 Toyota Prius brake failure when exiting freeway (101) onto off ramp at rengsdorff Ave. , in mountain view. Roadway was slightly moist from light morning drizzle and accumulated oils on road but otherwise nothing unusual about road conditions. . . Exited freeway at approximately 30-35 mph and applied brakes but brakes did not engage and car skidded off the off ramp into a swale. . . Car became stuck in swale and suffered body damage to left side of car. . . A tow truck had to be called to drag it out of the swale. . . The brake problem was reported to dealer who did not acknowledge the problem and stonewalled me. . . Also reported brake problem to Toyota corporate headquarters (carlos a. Garcia) in torrance, CA and he would not acknowledge the existence of a brake problem in the 2006 Prius. Total cost of repair, rental car, towing , etc. Was approximately $5,400. 00.

I have 2006 Prius and I have brake failure frequently if I hit a bump, pot hole, manhole cover, railroad track etc. It is un-nerving as I feel as if I am airborne for a while as I know I have no contact with the road.

I believe that I experienced a brake failure. I was driving on a snowy local road. I do not know my exact speed, but I estimate it was about 30 mph (speed limit is 45 mph). I saw a car driving slowly in front of me and I tried to brake from about half a block away and was unable to do so. I put my foot on the pedal as hard as I could but it didn't seem to have any effect. Because I was unable to brake, I ended up hitting the car in front of me. After the accident, I distinctly remember looking at my feet to confirm that I had my foot on the brake and not the accelerator, and I had, indeed, had my foot on the correct pedal. There was little damage to the other car (mostly a broken fender, I believe). My car experienced considerable damage to a headlight, wheel, door and a bit to the engine, but was repaired. The service technician showed me that my front tires were a bit low on tread (but not completely bald). The rear tires had been changed within the last two months.

My Prius has always had issues with the brakes making a clicking sound when stopped at a light, etc. I have complained from day one and always been told it was normal. By 2008 the brakes were not working well at times and the pedal would go almost to the floor at times and not at others. The dealership checked this and told me there were no problems. In Feb 2008 the brakes completely failed while I was driving on a city street and the pedal went all the way to the floor and I hit the car in front of me. The dealership again said that there were no problems and that the brakes were fine. I have had numerous incidents since with the pedal going almost to the floor at times and not at others. If I hit potholes or am on really rough streets the traction control light comes on and I lose complete control of the vehicle for a few seconds with the inability to brake. The dealership has repeatable said there are no issues when they check the car. This week, on Monday, the battery died and I took it to the dealership for a replacement. As always, I asked them to check the brakes and now they say there is a major issue with the brake actuator that could cause intermittent loss of braking ability and that the car is not safe to drive. Since the car isn't under warranty now (but was when the accident occurred) they don't want to pay for the repair. They put me in a rental car for the past three days since they said my car wasn't safe to drive. Today they decided they weren't paying for the repair, after talking with "corporate", and that the car is safe to drive without the repair! when I check the NHTSA site I see lots of similar complaints about the 2006 Prius and am even more concerned than ever. If you have experienced a similar problem, please take the time to file a complaint to force an investigation of yet a new issue with Toyota and safety issues!.

Accident occurred in 2007. I was driving in moderate traffic on a two lane road. A car, two cars ahead of me, slammed on their brakes, and forced everyone else to quickly brake. I also slammed on my brakes, to avoid a collision. My brakes failed to respond in time, and resulted in my rear ending an SUV in front of me. The accident caused several thousands of dollars worth of damage to the front end of the car. No air bags were deployed.

In November of 2007, I was driving my wife's 2006 Toyota Prius to take the family to lunch. I approached the intersection, I was on the cel phone, and the brakes failed to work and I crashed into a truck who was out in the intersection, causing damage to the front end of the Prius. My wife had been complaining for months that the Prius had brake failure incidents once a month. I would test drive the car, and could not get the brakes to fail. That is until the incident mentioned above happened. I immediately drove the car to the Toyota dealer. I informed them that the brakes failed. I informed them that they would need to drive the car every day for a month before they could get the brakes to fail. They kept the car for a month, but did not test it as I recommended. . . . . . And informed me that they could not see any problem, forcing me to pay out of pocket for the damages to the car $1,566. 57. . . . As well as for the $1,440. 38 rental car bill. I immediately picked up the car and drove it to another manufacturers dealership and traded it in on Honda accord. There was no way I was going to risk my families lives, driving that car another day. State farm claim number #[xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S.

I have a brake problem with my 2006 Toyota Prius. Several times (at least 6 times) the brakes have failed to function when I try to stop. The car does not respond when I press the brake pedal and continues to move forward several seconds. So far I have been lucky and not have had an accident but it has been close several times. I have taken the car to the dealership twice but they have not found any problems. They tell me that in order to correct the problem, they must replicate the problem in order to fix it and so far this has not been possible. This keeps happening and I feel very unsafe while driving.

I have now had three separate incidents of the brake failing on my car: March 15, 2007; December 4, 2008; and January 16, 2010. On March 15, 2007: I was in stop and go traffic on the freeway, traveling about 15 mph. ¿ I was rolling, with my foot off the brake and accelerator. ¿ the car in front of me (about 3 car lengths) put on brakes. ¿ I applied my brake, and it felt normal, but the car did not stop. ¿ I kept my foot on the brake and tried to press harder (pressing on the brake and getting no response was very disorienting; I actually checked to see if my foot was on the brake. ) it was the car in front of me that stopped me, not my brakes. ¿ after I was stopped by the collision, my brakes worked again. I filed an accident report with my insurance company, and I had the car towed to the service department of the Toyota dealership in carlsbad CA where I bought the car. The car was quarantined by your company. I was without a car for several days until a Toyota inspector came to the dealership to inspect my car. The inspector found nothing wrong and the car was returned to me. On December 4, 2008, similar circumstances: I was in stop and go traffic, traveling about 10-15 mph. ¿ I was coming to a rolling stop as I approached a red light. There was one car in front of me. ¿ I applied the brake, but the car did not stop. ¿ I took my foot completely off the brake and slammed it back down onto the brake. The car stopped, but I very nearly bumped into the car in front of me. ¿ I took the car to the Toyota carlsbad service department again. ¿ they inspected the brake system and checked the codes, and couldnt find anything wrong. The third brake failure happened on January 16, 2010. The brake failed when I was parallel parking. I took my foot all the way off the brake and pressed down again. The brake worked on the 2nd attempt. Luckily, I did not hit the car in front of me. I did not take the car back to the dealership svc dept; I knew it would do no good.

I have a 2006 Prius. I have experienced the braking problem that is reported for the 2010 Prius for the entire time I have had this car (since 2006). Occasionally the brakes will fail for a fraction of a second when braking over an uneven surface (train tracks etc). By now I am used to the problem though it does seem to occur more frequently over time. This problem is obviously not confined to the 2010 model. I reported the incident date below, but this is a frequently recurring problem.

2006 Toyota Prius brake failure - car suddenly accelerates forward when braking and running over a discontinuity in the road or wet pavement.

I've a 2006 Toyota Prius. Traffic stopped for a red light and I was behind a cement truck. I slowed to a complete stop about 5 ft. Behind this truck. All of sudden I noticed my car started moving forward with my foot still on the brake. I stood on my brake and couldn't stop the Prius. It contacted the cement truck causing a dent on the right side of the hood and a crack windshield. The consumer stated as traffic began to stop for a red light, he began braking from about 25 mph which seemed normal. He continued to gradually slow the vehicle down at a distance of about 5 to 10 feet, the consumer estimated his speed was about 3-5 mph. The brakes locked up and failed to stop the vehicle, consequently the consumer rear ended another vehicle. The brakes felt hard, not spongy and not pulsating. The vehicle lost all braking completely. Updated 01/10/07.

The Prius brake failure has occurred several times since I bought the car in late 06. If I am on a wet road or a gravel road, it seems that when pushing the brakes, they not only fail but the car lurches. When this occurs a light in the dashboard goes off simultaneously. I contacted my dealer about it 2 years ago and was told it was not a brake failure but was just the way the technology for the brakes worked and that the car was fine. I was involved in a 6 car pileup almost one year ago, in which I was the 2nd car in line. The light went off during the accident itself and I believe that the braking might have been the cause of the wreck, now that I am aware of all of this. It felt almost exactly the same. I just assumed the car behind me was pushing me forward, but no at fault party could ever be determined. I called the dealer again today asking (since my car is still under warranty) if this could be repaired since it was now acknowledged and was told that until a recall occurred, Toyota corporate had not informed them of a fix so nothing could or would be done. I find this unacceptable, as I am driving a vehicle I am paying a lot (for my income anyway) and it is so unsafe. I carry my newborn around in this thing! not only are the brakes a concern to me but the Prius is also part of the floormat recall so you couple the two issues with brake and acceleration and you are asking for extreme risk when driving. I am very concerned that the car I am paying so much for is so risky to drive and would like to have Toyota recall the car and repair this problem.

Brake failure in Prius 2006 model. Car did not stop near a signal light, and would have hit another car infront of mine. Finally ended up driving into another lane fortunately there was no opposition traffic. In the second incident car did not stop for 15 ft near a stop sign, where there was a little snow until abs acted. In both cases we got lucky. This needs to be investigated not only for 2010 model Prius but also for previous models.
