Traveling straight forward at 40 mph and approaching a red light. immediately upon depressing the brake pedal, an alarm sounded and the abs, brake, and traction control warning lamps lit up on the dashboard, and my prius completely failed to brake, continuing unabated toward the other vehicles stopped at the red light. i began pumping the brakes and was able to build up pressure and safely stop without collision or further incident. my local toyota dealer diagnosed the problem as a "brake accumulator internal leak. recommend replace brake accumulator". this needs to be recalled, this is egregiously irresponsible by toyota, i easily could have been hurt or killed.
I was driving on the freeway. all of a sudden brake, abs and suction traction light turned on. after that i have to push my brake harder to slow down the vehicle. i was able to drive it back home safely. i took it to the dealer who said i need to replace brake master cylinder with brake booster. doing research i found many owners of the same model car have same problem and some of the cars are recalled but not all. i believe most of 2010 toyota prius car have issues with brake system which is bad for our safety. it can cause serious harm for our safety. i request your good department to investigate the braking issues for 2010 toyota prius vehicle. as a good citizen of the country, i felt i need to discuss this issue with you.
tl* the contact owns a 2010 toyota prius. the contact stated that while driving at approximately 45 mph, the brakes operated independently while the contact was depressing the accelerator pedal. the vehicle was taken to jack taylor toyota on 3750 jefferson davis hwy, alexandria, va 22305 where the diagnosis was undetermined. the contact mentioned the pre collision system was deactivated however, the failure persisted. the manufacturer was notified of the failure. the approximate failure mileage was 95,250.
Abs brake light stays on all time.rear wheel gets extremely hot,
Abs and break light lit while going 55 mph. lost antilock break feature. local port st lucie tire and break diagnosed bad master cylinder and nitrogen leak into break lines. found recall on similar 2010 prius' due to nitrogen leakage into break lines
Abs light came on. diag code: c1391. abnormal leak in accumulator. this problem is similar to a recall on prius 2010 for abs brake issue. however, toyota said that my prius is not part of the recall. i would like to request toyota to fix this problem for my prius 2010 so that i can safely drive this car.
Tl* the contact owns a 2010 toyota prius. while the contact's wife was driving 35 mph, the abs, traction control, and brake warning indicators illuminated. the driver had to apply extra pressure to the brake pedal to slow down the vehicle. the vehicle was taken to an independent mechanic who diagnosed that the brake booster and master cylinder failed and needed to be replaced. the vehicle was repaired. the dealer was not contacted. the manufacturer was made aware of the failure and stated that the vehicle was not within the vin range. the approximate failure mileage was 95,000.
Brakes turned to mush - pedal went all the way to the floor with almost zero stopping power. sounds like a similar recall from 2013 or so. going 45 mph (speed limit) on a busy 4 lane hghway approaching stoplight and slowing traffic for red light at intersection of another 4 lane road. brakes mostly unresponsive. almost went through intersection and narrowly missed hitting a slowing car. braking did not engage per usual activation position and pedal went to the floor instead. car was just serviced a week ago for unrelated recall item. car has been maintained diligently since new purchase in 2009, getting all recalls serviced promptly. maybe the range of vins in the older recall was not wide enough?
All brake lights come on (brake, abs and traction control) and power assist breaking stops working and brakes feel very weak. brake actuator runs frequently when lights are not on. there are many complaints online and toyota claimed they fixed this issue in 2009 and extended the warranty for 2009 and earlier, but the problem is clearly not fixed.
On a few occasions when the car is in motion, we have depressed the brakes and they did not grab right away. this happened once getting onto a highway, twice on a city street, and another time on a country road. there seems to be a small delay before they will grab, causing the car to feel out of control for that brief moment. it feels unsafe when this happens and doesn't seem normal. we contacted the service manager at toyota to have the car looked at, and he did not return our call.
This afternoon, my wife was driving down a two lane, paved street at about 25 mph. the street has a slight decline and she began to apply the breaks to slow down slightly. just a second or two later, she hit a small bump in the road and the car accelerated (while she had her foot on the break) for a fraction of a second. we didn't hear the sound of the engine revving. thankfully, there were no other cars on the road at this time and there was time to press the break again. based on looking around online, many people have reported similar issues (http://www.consumerreports.org/cro/news/2010/02/toyota-adds-2010-prius-braking-problem-to-the-list-recall-possible/index.htm).
When i am coming to a stop (braking normally) and hit a bump, the car surges slightly and the brakes become less responsive. it feels like i'm fighting the engine as it accelerates and i'm trying to brake against it. releasing the brake and attempting again seems to be a solution, but i often don't have time before reaching the intersection i'm approaching. this consistently happens in two places in my daily commute with a slight buckle in the road approaching an intersection on city streets and county roads.
Driving down highway at posted speed limit (75mph), i tried to slow down due to traffic and noticed my cars ability to brake was severely compromised. i then noticed my cars brakes, abs, master warning and vsc lights had came on. given that my car has 103k miles on it, i figured it is time for a brake pad service. with the limited braking ability, i decided to make the short drive to the toyota dealer for brake service. after the dealer inspected my car, a representative told me that it is not the brake pads that are causing the lights in your dash to go on but rather the brake booster. they advised me that it is not recommended that i drive the car anymore until the issue is remedied by replacing the brake booster at a cost of over 2k. i had to also incur the cost of a rental since the booster was not in stock and would take over the weekend to receive. i was taken aback by the total cost of the service but had no choice and proceed to get it repaired. upon receiving my car a few days later, i drove to work and upon my return home, the issue repeated itself with all the lights on the dash lighting up and the cars braking ability was again compromised. extremely irate, i drove directly to the dealer and upon inspecting the car they told me that it is now the accumulator that needs to be replaced. this time the dealer absorbed the cost of over 3k to replace it. i researched the internet for any known recalls and found the issue was being addressed by toyota with a recall however my cars vin was not part of it. it is my hopes that you make toyota aware of the safety issue and initiate a recall on all 2010 prius models and not just some. i would also like to get the cost i incurred with this safety issue reimbursed at some point.
Turning left after a stop sign on a single lane street (30 mph), suddenly the dash board started flashing 'stop car' warning and continues beeping. also, realized that applying break paddle did not help a bit. it was hard to press the paddle that moved a little bit. going straight about 300 ft. car reduced to idling speed. turning left into a parking lot of a school, i tried stopping it into a parking space. break did not work again. so, car stopped after hitting the curb. toyota dealership was called and arrangements were made to tow away car from school's parking lot. the car did not stop when towing person tried to reverse drive. somehow he managed to maneuver it on a tow truck. i was informed by dealership that break assist system (bas), built into prius hybrid model, failed. the system comprises of accumulator & pump that assists to stop the car when break paddle is pressed. though car was covered under warranty, break system and associated components were not covered. repair cost over $1900 to replace bas. purpose of this complaint to highlight nhtsa of the critical failure of prius design to allow break system to fail in such a colossal way. the car could not be stopped. this is a serious driving safety concern. any failure of break assist component should never ever take away this critical control. intent of this complaint is for the public safety, having toyota informed of the incident. it has been very disappointing that toyota has not given any response except giving a case number by a customer service center. request nhtsa to look into the incident and most importantly review design of break assist system for prius in the interest of public safety and defensive driving. please advise should nhtsa require further details or incident narrative.
Leak of nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.
The brake booster pump assembly failed, which left me with no brakes and in a life-threatening situation. the vehicle was in motion and i narrowly avoided a bad accident on a city street.
Tl* the contact owns a 2010 toyota prius. while driving 20 mph, the braked pedal was depressed and failed to operate as intended. the contact stated that several warning indicators illuminated. the vehicle was towed to an independent mechanic to be diagnosed. the contact was informed that the brake booster pump failed and needed to be replaced. the vehicle was not repaired. the vehicle was not included in nhtsa campaign number: 13v235000 (service brakes). the manufacturer was notified of the failure. the approximate failure mileage was 100,000.
The brake actuator failed on our 2010 prius iii manufactured in october 2010. toyota is covering problems with this same brake actuator for 2010 prius manufactured between march 2009 and early october 2009. my vin did not fall into that date range even though mine was manufactured in october 2009, so the brake defect should be extended to beyond the early october 2009 manufactured date. the symptoms to this problem were the brake, abs and traction control warning lights came on, no regenerative braking and the braking distance increased.
I change the brake booster twice and hace the same problem. my brake pedal loss of braking ability or slipping brakes and the warning brake, abs and traction light permanently on, and no cruise control works at all
Abs + breaks + tcs lights are on and my car's breaks are not working it was about to hit with next car but my speed was under 30 that's why i reached safely. i showed it to just break and they said it's required ecu update. it's a software problem in this model. i don't know how to update software. is it possible if i get free update from toyota dealership ?
I applied brake on a red light which is as usual for me and i noticed car didn't slow down and kept moving past the red light. it has happened before and the it happens on uneven and even on minor potholes. the brakes on the small bumps and minor uneven roads completely loose traction of the tires and car even faster with the brakes on when trying to stop over minor uneven roads. mechanic said it's oversensitive anti locking brakes that cut off the brake power even when it detects minor disturbance in the sensors. *tr
Tl* the contacts owns a 2010 toyota prius. the contact stated that the brakes traveled to the floor when the brake pedal was depressed and the vehicle did not decelerate normally. the dealer diagnosed that the actuator system needed to be replaced. the vehicle was not repaired. the manufacturer was notified. the failure mileage was 92,514.
My wife was driving on the highway when her brakes totally failed. she applied brake pressure as hard as she could, but it had not effect. fortunately, since she was in the left lane of the interstate highway, she was able to coast to a stop in the left hand shoulder. several red lights lit up on the dashboard, including the brake and abs lights. i had the car towed to world toyota dealership in atlanta. they said the brake master cylinder failed. i paid them to fix it. see attached work order from world toyota. *tr
I have a 2010 toyota prius. when trying to slow down, any time a bump is hit, (or a pothole) the braking power significant decreases . this greatly increases the stopping distance and is very scary in traffic and in winter driving. is this a problem? i called toyota earlier for the same issue and they told me that this is normal and this occurs because only one tire is hitting the pothole or bump' it is very scary and i have to leave a lot of space ahead of my car.
I recently purchased a toyota 2010 prius and four dash warning lights appeared the day after i purchased it when i turned the car on in the morning. the lights stay on for hours to days and go off for similar amount of time. when the lights are on the brakes are much less responsive and the braking action does not charge the batteries as much, never more than 25% of charging potential. the problem was diagnosed as a problem with accumulator in the brake system. i performed a search online and found that there is a recall for such problem, but my vehicle was produced a month after the date of production that would qualify for this recall. i will a pdf copy of the recall i'm referring to.
Complete brake failure when stopping for stoplight on hwy 53/midway road. resulting in 3 car accident. this was the second brake failure. the first complete brake failure happened when backing out of parking space at work location. brakes were pressed , car kept backing up hitting a parked car behind us. after the first failure the local toyota dealership drove the car and also experienced total brake loss after driving it for a bit. the toyota dealership replace the brake cylinder assembly. *tr
Hello. i recently started to experience an issue with my vehicle. my brakes started to make some kind of unusual noises every time i press on them. i've never had that before and i service my car pretty often. i went to authorized toyota dealership and they told me there was a computer issue and they fixed it for $110. it continued to make noises and all of the sudden it began showing abs/brake/vsc lights on my car dashboard either while i was driving or being in the 'park' mode. at the same time my brakes stopped working well while driving when the abs/brake/vsc lights were on. i checked the code of the error through the car computer and it showed me 'c1391'. i went to the dealership again and they did another check and this time they found that brake master cylinder/booster/abs assembly needs to be replaced with $3,170 price. i attached here the paper that my toyota prime dealership located here in saco, me gave me. i've been reading a lot about it online and people with the same type of hybrid vehicles have experienced it. i think toyota needs to look into the issue and acknowledge that it is a common problem in their hybrid vehicles. i service my car all the time, i do oil change and check all the systems very thoroughly, so i don't understand why we, consumers, have to pay that big of a price for the car repair. i hope you can look into the issue and help me (and to all other car owners) to resolve this kind of issue. thank you.
My car is making a weird noise coming from the firewall. my traction control lights are on, brake, and a couple other. it turns off and then will turn back on.
I went to start the prius after work, after i pressed the start button, several alarms went off on the main panel. alarms included the master alarm, abs, brake, check engine, and an incessant beeping. there was also a repetitive sound coming from under the hood that sounded like the braking system was trying to build pressure, but was not successful. i towed the vehicle to the dealership and they diagnosed this as the master brake booster assembly. the quote was $2500 for the part, and $500 in labor. they started work on the vehicle, then called and said that they would have to replace the accumulator as well, even though it was already replaced during the original recall. they contacted toyota corporate who paid for the accumulator, but would not cover the additional labor to install the accumulator. the total bill was $3900. this seems like a common problem with the prius family. my car had approximately 92,000 miles.
Tl* the contact owns a 2010 toyota prius. when the brake pedal was depressed at 35 mph, the vehicle skipped, jerked, and hesitated to respond. also, the abs and traction warning indicators illuminated. the vehicle was taken to an independent mechanic where it was diagnosed that the brake booster pump assembly accumulator was leaking and needed to be replaced. the vehicle was not repaired. the manufacturer stated that the vin was not included in nhtsa campaign number: 13v235000 (service brakes). the failure mileage was 141,000.
Tl* the contact owns a 2010 toyota prius. while driving approximately 5 mph, the brake pedal had to be depressed to the floorboard to stop the vehicle. the traction control, abs, and brake warning indicators illuminated. the vehicle was taken to the dealer where it was diagnosed that the brake pressure accumulator needed to be replaced. the manufacturer was notified of the failure. the vin was not included in nhtsa campaign number: 13v235000 (service brakes). the approximate failure mileage was 75,000. the vin was not available.
Brake system failure while driving on suburban street. master cylinder, assembly and booster replacement. all corresponding warning came on. was able to drive to dealer. this is the exact problem that incited the recall for nitrogen leaking into the brake system in some prius made in 2010 (82,000). cost of $3200. incidentally, brake fluid was flushed and changed at 60,000 and then again at 75,000. the reason, stated from the dealer is that maintenance was responsible for the failure. priority toyota of springfield was the only one during the maintenance and i followed their recommended advice for the 2 brake fluid flushes and replacement.
I am experiencing a resurgence of the acceleration while braking phenomenon that was the basis of the 2010 recall. we had the car fixed at the time of the recall. the incidents relate to when i am braking and happen to go over a bump or hit a pothole. as i am breaking the car suddenly accelerates forward and you have to keep breaking harder to keep from having the car get away from you. it is now happening almost consistently. after calling the local toyota dealer and the general toyota number, i find out that they are not willing to apply the same fix as they did in 2010. i am now forced to take the car in and have it diagnosed and don't know what they will charge me for that. then toyota said i could call them back to see if there is anything they can do i don't understand why they don't have to stand by a fix that is not related to wear and tear but rather a malfunction in the way they built the car. it should never be right to have a car accelerate if one is braking. the only damage to date has been a glare from a construction worker who was telling me to stop only to see the car lurch toward him.
I was in a parking structure going approximately 15 mph when i removed my foot from the accelerator to press the brake. before i could get my foot to the brake, the car quickly accelerated. it took at least two attempts at pushing the brake peddle before the car came to a stop. and, to be honest, the guardrail the car hit helped actually stop the vehicle. it was totally unexpected and extremely scary. in hindsight, i should have suspected that there may be a problem when i noticed that sometimes when applying the brakes to come to a stop there would be a feeling of the brakes slipping and the car lurching forward a bit. the dealership had the car towed in to get checked out, and i have been told that they will notify toyota. in the meantime i am concerned about the safety of this car!
Tl* the contact owns a 2010 toyota prius. the contact stated that the brake pedal required to be depressed several times in order for the vehicle to come to a stop. the abs, the traction control, and the brake warning indicators illuminated. the failure occurred intermittently. the vehicle was taken to a dealer where the failure could not be duplicated. the manufacturer was not notified of the failure. the failure mileage was approximately 159,000.
Tl* the contact owns a 2010 toyota prius. the contact stated that the brake booster assembly on the vehicle was defective and failed to operate as needed. the vehicle was taken to (greentree toyota 87 federal rd, danbury, ct 06811) to be diagnosed. the mechanic was unable to retrieve a fault code. the vehicle was then taken to (curry toyota of connecticut 832 straits turnpike, watertown, ct 06795) for a second diagnosis with the same results. the contact became aware of nhtsa campaign number: 13v235000 (service brakes). the vehicle was not repaired. the contact received a buyback offer from green tree toyota but declined the offer. the manufacturer was notified of the failure. the failure mileage was 93,000.
I have driven people for a living for over 30 years. i bought a prius because of fuel costs. a month ago while transporting passengers, my power brakes go out and my dash lights up with abs,brake, & traction control warning lights. i take it to the toyota dealer who charges me $111 to tell me i have a brake problem and that it will cost $4418 to fix it. code # c1391; they recommend replacing the master cylinder; and booster pump assembly saying there is an abnormal leak down of the brake accumulator. this is insane. i cannot afford to fix it and must continue to work to live; therefore driving about 200 miles/day with hydraulic only brakes. my research indicates there was a major recall for this exact problem on the 2010 model. the dealership and toyota corporate both say my vehicle was not part of the recall. i feel as though it should be since, obviously, the problem has not been solved. i am not alone, as many owners on priuschat have the same problem. this is a major safety concern to not only myself, other vehicles or pedestrians, but also my passengers. an expanded recall is necessary and warranted. anything you can do will help and make us all safer. .
Tl* the contact owns a 2010 toyota prius. while driving at an unknown speed, the brake pedal was depressed but it took a greater amount of time to stop the vehicle. the contact applied excessive force to the brake pedal. the abs and brake warning lights illuminated. the vehicle was taken to a dealer where it was diagnosed that a brake pump needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the vin was included in nhtsa campaign number: 13v235000 (service brakes). the failure mileage was 96,000.
On 05/25/2016 at about 9am, while in motion at a rate of speed approx 25 mph on a street during construction (don't know if the bumpy road had anything to do with it), the change oil soon light appeared and seconds later all the lights on the dash came on with the message to check the "check hybrid system" . i tried to stop the vehicle and it kept accelerating. i pressed on the breaks really hard and the traction control light kept flashing on and off like crazy but it barely had any impact. although the vehicle slowed, it did not come to a full stop. i ended up hitting the vehicle in front of me. thank god it was a truck and as able to stop the car from moving further or i could of ended up in the middle of an intersection. after the collision, the car would not stop although the park button was pressed and light was on. i even tried turning off the vehicle and the vehicle stayed on and in drive. i ended up in the hospital and don't know how it eventually got turned off but that was very frightening. i had my children in the car. on impact, the seat belts did not even tighten.

Brakes suddenly stopped functioning while driving 55 mph on 4 lane highway. dashboard alarms also indicated there was a brake problem. per toyota technician at prestige toyota in kingston ny, gas bubbles contaminated brakes and ruined pump and actuator. according to toyota warranty assistance representative "fred," who spoke with local technician, there was a recall for this exact condition, but did not include my particular vin. i was very lucky not to have been in a serious accident, and i have to wonder how many other prius drivers are at serious risk because of similar condition.
Tl* the contact owned a 2010 toyota prius. while driving 45 mph, the anti-lock brakes independently engaged and the power steering and brakes failed without warning. as a result, the contact veered off the road and rolled over several times. the air bags failed to deploy. the contact sustained a concussion, fractured ribs, and several lacerations that required medical attention. a police report was filed. the vehicle was towed to a salvage yard where it was deemed destroyed. the manufacturer was made aware of the failure. the failure mileage was 48,000.
At 46,900 miles without any warning all the brake warning lights came on and braking effectiveness dropped off. have to push pedal to the floor to get the car to stop the lights for traction control, anti lock brakes and the word "brake" and another light like a circle are on all the time normally there is strong braking when first touch the brake pedal but now very limited braking until push down very hard on the brake pedal. looked at brake fluid and it is full, do not know why the brakes are not working
While driving home from work, the brakes went out on my toyota prius and the warning lights for abs, traction control, and brakes all came on. i still had a small amount of brake pedal left and the emergency brake continued to work. when the toyota dealer diagnosed the problem today, they said that it was a $3500 brake booster and that it was not covered under recall or warranty. the symptoms, the warning lights, and the results all match a previous toyota recall (d0h) exactly, yet they will not include my car under the recall because my vin is not part of the original recall. they're lucky i wasn't physically injured in accident caused by this. i suggested to their customer service rep that maybe my car should be included in the recall, but they did not agree.
I was driving my vehicle at about 35 mph on a two lane, hilly road. suddenly, the abs and warning lights started flashing, and there was a loud beeping noise. i pressed the brake pedal, and there was no response. since i was traveling uphill, i slowed and then used my emergency brake to come to a complete stop. after the vehicle was towed to a toyota dealer and diagnosed, i was informed that there was an internal leak in the hydraulic unit of the braking system, and that the abs pump module and brake master cylinder needed replacement. this was a very similar issue to a recall of other 2010 toyota prius vehicles, but the recall does not apply to my vin number. toyota claims that the problem was "remedied" before my vehicle was produced even though one of my trouble codes is the same as the trouble code referred to in the recall.
We came to the dealership at auburn blvd and they told us they don't have a parts for recal and it will take about a week to order them . they gave us a paper stating that the recal has been fixed for dmv purposes to renew the registration even though recal wasn't fixed. it has been more then 4 months and no one from dealership called us to inform us when they'll actually fix the recalled part. every time i call them they say they don't have part in stock and they don't know when they'll receive it. please help!
Tl* the contact owns a 2010 toyota prius. while driving at an unknown speed, the brakes suddenly failed to operate when the brake pedal was depressed. during the incident, the instrument panel lights illuminated and an audible signal was present inside the vehicle. the vehicle was taken to the dealer where it was diagnosed that the brake booster was faulty and needed to be replaced. the manufacturer was notified of the failure and the contact was informed that the vehicle was not included in nhtsa campaign number: 13v235000 (service brakes, hydraulic). the failure mileage was 98,000.
Brake booster pump assembly vehicle in motion when on highway when loss of breaking and steering took place. vehicle lighted icons appeared on dash along with alarm sound. (abs) (!) (brake) (ss). this unsafe condition could have been avoided if nhtsa would have forced toyota to recall this defective part in 2013 when toyota notified nhtsa of the defective braking system. or toyota mailed notice to customers as stated back in 2013, which prevention could prevent loss of life or harm. or class action. http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/ucm442011/rcmn-13v235-0909.pdf
Abs actuator with master cylinder assembly has internal leak. assembly doesn't hold pressure and actuator motor continiously working in order to create the pressure. due to this problem brakes are not operate as properly. it takes more strength to put on the pedal to stop vehicle. i also noticed that during emergency braking not all wheels were involved equally. due to this problem braking distance significantly increased. i have 3 instrument cluster error lights turned on due to this problem: "brake", light with vehicle on sleepy road, and light with "!" sign. i found that there already was recall for same 2010 year toyota prius under tms-ntc-13178 of july 23, 2013, toyota recall name d0h, but my vehicle is not covered. i kindly ask you to investigate if my car eligible to participate in this recall campaign, since seemsthat this car were assembled with same unreliable parts.
Driver made a sudden stop to avoid an accident on 2/16/15, engaging the brakes. afterward the brakes alternated between being hard to push and being soft to push. driver parked the vehicle 5 minutes later. the next time the car was turned on(approximately 60m later), the car began beeping and showing three error lights - abs, (!), and the traction control symbol. after running diagnostics, the driver was told by a mechanic that the problem sounded exactly like a previously issued recall (tcp-d0h); however, toyota has indicated that our model is outside the scope of their recall. given that we have the same make/model/year car as the recall and the same issue described, the situation is highly suspect. in addition to insuring my own family's safety, i'm hoping to make sure this potentially dangerous brake issue isn't more widespread than toyota has admitted.
