A known defect was briefly recalled, then sunsetted. My brake attenuator has failed, as has been the case for many others on this model. Toyota has acknowledged the defect, but no longer supports it.
2010 Toyota Prius brakes complaints
Page 7 of 66: complaints 161 to 190 of 1,945, newest first, as owners wrote them.
Normal braking pressure failed to stop the vehicle requiring the driver to apply very heavy pressure to stop the vehicle and avoid a rear end collision. Multiple dash lights appeared and the vehicle was towed to a Toyota dealer. The dealer confirmed codes C1252 and C1256 exist and recommended that the brake booster pump assembly be replaced. An August 6, 2018 Toyota Service Bulletin (T-SB-0079-18) recognized this problem. Toyota sent Customer Support Program Notification ZJB noting that "Toyota has received reports about certain internal malfunctions of brake booster assemblies in some of the subject vehicles. In these reports, customers have noted various brake system related warning lamps illuminated." Toyota noted that, "This is not a recall." Toyota suggests that certain warning lights may illuminate but does not warn drivers that normal braking may cease and that the vehicle can be dangerously difficult to stop.
ABS brake light on. Just purchased this vehicle and found Toyota knows of a defect in the master brake cylinder that causes it to leak. Toyota was repairing this problem free of charge till 2019. This vehicle has never had the repair. I am told brakes may go from power brakes to non power brakes while driving. We are not driving till it gets fixed because of safety problem with brakes.
There is a known problem with 2010-2015 Toyota Prius brake actuator assembly and also the brake booster pump assembly. A leak develops and cannot hold proper brake pressure which will lead to catastrophic failure of the system and a life or death brake failure. Toyota has acknowledged the problem and issued a recall only covering 150,000 miles or 10 years from date of first use. This recall should be extended to all affected vehicles for the LIFETIME of the vehicle given that it is a known manufacturing defect affecting life and limb and that repair costs average over $3000.
Brake booster/ brake pump / accumulator sudden failure BELIEVED TO BE CAUSED BY THE SENSOR WARNING SYSTEM â ï¸ THAT ABS LIGHT ASSOOCIATED WITH CONSTANT BEEPING NOISE, 10 SECONDS LATER LOSE OF BRAKE POWER. factory trick to get brake service, at large for this repair costs 3800 per dealership toyota carlsbads. Manipulative recall ð¤ disallowed me on 3 occasions unable to get part replaced by Toyota. When contacting corporate the did not demand me to get fixed and not drive NY car, again getting my car to tge service station experienced noise occurring then sudden outage of brake power reduced to nothing. A similar youtube video and my personal video explain sudden loss of brake power or pressure... after lights go on. And immediately return to normal after lights get reset. Sensor failure leading to brake failure, really scary and obviously a big problem TOYOT SHOULD STILL BE RESPONSIBLE FOR. CONSUMER SERVICE PROGRAM BY TOYOTA FOR THIS BRALE BOOSTER ISSUE STOPPED FOR SOME REASON IN 2019 ALSO. 150K BS RULE. MERCEDES BENZ HAS TAKEN THE RIGHT ACTION TO FIXING BRAKE BOOSTER ISSUES.
Hi- I have a Toyota Prius 2010 model and I encountered a braking failure yesterday. My ABS lights, brake lights and another light came up on my dashboard of the car. Upon diagnosis, I was informed by Toyota dealership that my car has a faulty C1391 - Abnormal leak in accumulator. This condition may be caused by small internal brake fluid leak inside the brake booster assembly with master cylinder. This is a known issue by Toyota and lots of press coverage on this issue since the past few years. I was told today that if this issue occurred within 10 year or purchase or <150K then the repair work would be covered by Toyota. I purchased the car in 2010 and I past the 10 year mark but mileage coverage is 125K (<150K). Toyota is unwilling to bear the cost and would want me to pay for the fix. This is a known issue with Toyota and the braking system can fail anytime before/or after 10 year mark. It is now costing me $3000 to repair. I am shocked with the Toyota's response in this matter. There are lots of blogs I read online who have similar issue. Class Action lawsuit: https://www.classaction.org/news/toyota-hit-with-class-action-over-alleged-refusal-to-fix-braking-system-defect-in-hybrid-vehicles Here is one example: https://www.youtube.com/watch?v=xA9jyrbZDWo Thanks.
The Traction control, ABS, and Brake light all came on simultaneously. It was random with no trigger. The brakes feel spongy, and will not regenerate to charge the hybrid system.
The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal was depressed however, the vehicle failed to respond as needed; causing the stopping distance to be extended. The contact stated that the ABS, brakes, and traction control warning lights were illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the ABS system and brake booster needed to be replaced. The local dealer was contacted and the contact was informed that the federal safety agency Campaign Number: 10V039000 (Service Brakes, Air) had expired. The manufacturer was notified of the failure but provided no assistance. The approximate failure mileage was 220,000.
My brakes have been making hissing noises whenever I press on the brake pedal for the past year. While driving on the freeway 300 miles from my home, numerous lights on my dashboard came on including brake, VSC, PCS, ABS, Triangle and "CHECK PCS SYSTEM" warning message. The brake also makes pumping noise every 4 seconds. The vehicle has no regenerative braking. The brake pedal is mushy and doesn't slow the car down until the pedal is fully depressed. I contacted Toyota and was told that there was a Customer Support Program ZJB that covers 2010-2015 Prius Vehicles for Brake Booster and Brake Booster Pump Assemblies. However, that program only covers 10 yrs 150 miles. My Prius has 110k miles but it's 21 months passed the program coverage. The car is dangerous to drive and Toyota will not honor the recall. I am stuck with a car with no brakes.
On March 25, 2022, I was driving my 2010 Toyota Prius, approx. 209,000 miles. When I had parked my vehicle, and turned my A/C on, my vehicle started to make this annoying beeping noise non-stop and all of the light on the dashboard had lit up. My brake lights, ABS, and the slip indicator all came on. When I went to drive my vehicle all of sudden my brakes did not respond. I had to force break and push down on the brakes very hard, to the point where I'm flooring the brakes. I checked with Toyota to see if there was a recall on my vehicle, and they told me that there were no recalls. When I did my research on 2010 Toyota Prius, I found that this is a common issue that the brake actuator and brake booster pumps are faulty on these vehicles. I did not receive a recall notice for this vehicle. Currently, my vehicle is not drivable and not safe to drive. For this to happen out of nowhere with no warning is unacceptable.
As 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.
A number of things have failed on this car. 1. The hybrid battery pack system shut down and warned that I needed to see a mechanic. My mechanic diagnosed that the hybrid invert was defective and causing the battery pack to fail. 2. When braking at both low and high speeds, the car increasingly struggles to come to a stop. When applying foot pressure, you can hear the pump winding - this occurs while at rest as well as when trying to slow the car down. There are times when applying the brake that the floor pedal will lock and cause the car to skid while barely reducing the speed of the car. I have had multiple near accident incidences as a result and put myself and others at risk. 3. The car ferociously vibrates every morning - discovered that the head gasket has failed prematurely and due to the car overcompensating for the failing hybrid battery that is being impacted by the failing hybrid inverter. All problems have been reproduced and diagnosed at independent service centers. Multiple codes, warning lights and messages have alerted me to engine and battery issues - all of which appeared after the various issues and failures.
2010 Prius Brake, ABS, Traction Control Lights On/Off with no codes I bought new car and running smooth so far. I got this lights 2 months back and off for sometime and came back on and off and now quite often coming back and forth, 106K miles had the ABS, Traction Control and Brake light all come on at once same time and off same time and back and forth. No codes and no flashing but this is very critical as all related to brake systems failures may leads to crash because we don't know when this lights on and off and no codes to fix this issue.
Brake system fails under normal driving conditions. Dealership diagnostics confirmed this falls under the Customer Support Program ZJB. This program expired in 2020 and Toyota customer care is unwilling to fix or reimburse for the $2200 expense associated with the defective brake booster and brake booster pump assembly. The Toyota case number is #220318001387.
For the past 2 weeks my prius has been acting very strange. When driving I have a hard time coming to a stop when pushing the brake and I realize that that the ABS light is on as well the brake light is on. Sometimes it will work fine with the lights off, and somtimes it messes up again. I heard that it could be a brake booster or module. I believe it was already recalled a few years ago, but seeing a lot more people complain about recently is a bit concerning. The part that was replaced, it should work for many years not less than 10. Its a huge risk for myself and others. I didn't realize what was happening until I needed to stop fast. This needs to be fixed fast and the right way this time before somebody dies
Brake warning lights, traction control, and ABS warning lights all illuminated on the dash. Taken to the dealership and was told brake failure due to actuator or brake boost. Upon further research, it looks like this is a known issue with the Prius but Toyota is only providing service/repair to certain vehicles who already show brake failure instead of issuing a recall for all potentially affected vehicles.
In Nov 2020 I was informed that my ABS actuator needed to be replaced since all warning systems went off and brakes were disabled. On March 13, 2022 the ABS and traction system warning came on again . On March 14, 2022 I had my car towed to Daves Ultimate Automotive in Austin, Texas because my brakes failed. They told me I needed to replace the Brake Booster which is going to coat me $2500. I have looked at car complaints and this seems to be a faulty system that Toyota is aware of because they extended a warranty to Dec 2019. It is my belief that this should be a recall because of the dangerous potential of no brakes when this system fails.

The Brake booster and master cylinder failed causing the braking system to fail while driving
My prius appears to have the same problem that an excessive number of other 2010 priuses have with it's regenerative braking. This is a common and well known issue among these cars. Despite the fact that I am at 132k miles, under the 150k limit for the extended warranty, I am going to be stuck spending thousands and thousands of dollars to get my vehicle fixed because it is about 2 years past the 10 year limit.
2010 toyota prius. Consumer writes in regrds to defective ABS system. The consumer stated the dealer advised the brake accumulator. The consumer was informed about a recall but, it had been discontinued. The brake booster pump assembly was replaced at the owner's expense.
While driving, my traction lights, ABS light, and Brake light came on the dash with no noises or other messages. I noticed my brakes took significantly more distance to stop and then stopped working altogether. I had to use my emergency brake to get stopped safely.

The brake assembly is noisy while stopped at lights. The brake pedal continues slowly downward when pressed as if there is a leak in the brake master cylinder. Toyota has issued a warranty extension for a problem of fluid leaking in the brake booster, but did not notify me. Toyota's code for the warranty extension is Customer Support Program ZJB. Two local dealerships have refused to perform the repair because the warranty extension expired before I became aware of the issue.
2010 toyota prius brake booster failure. according to multiple resources online, there have been known issues with this part from Toyota across multiple models. After recalling only a small portion of vehicles due to this failure, complaints have been filed with the federal safety agency to address toyota's lack of corrective action regarding the vast amount of vehicles utilizing this technology. this is a dangerous defect that caused my brakes to malfunction during a cross-country trip. my brake and ABS lights suddenly came on, and i could tell my prius handled differently. the brake pedal became hard to depress and stop time increased drastically. i am having a mechanic diagnose and repair this issue costing no less than $1200 in austin, TX. i would like to make a complaint to toyota for not recalling all the models with this issue and instead choosing to recall a minute fraction of potentially defective vehicles.
Brake Booster Failure; has been inspected and confirmed. Warning lamps for traction control, ABS, Brake System Lights, Master Warning Light all came on during normal city driving. Immediate loss of Brake Assist causing sudden need for much more distance while stopping the vehicle. Clearly, sudden changes in brake behavior is a safety concern and this problem seems to be well documented as common issue in this era of Toyota vehicles. I believe Toyota has fallen short in its efforts to remmedy the situation. An extended warranty was issued but it was for a brief period of time that required this problem to occur within a narrow window. It's a wildly expensive repair to a critical system and it seems to be a common problem in these cars.
We have a 2010 Prius Purchased March 2010. Toyota issued a "Customer Support Program" (free extended warranty) for the brake booster and brakebooster pump assemblies in 2019. The Primary Coverage was offered until 11-30-19 regardless of milage. After that the secondary coverage applied for 10 years or up to 150,000 miles. The information mailed to us states; "If you have not experienced the condition described above, there is no action necessary at this time." We did not experience any brake problems until 11-10-21, when the dash display lit up with the BRAKE LITE, ABS LITE, SLIP INDICATOR LITE, AND THE ! LITE, ALL CAME ON AT THE SAME TIME. ALSO THE BRAKE PEDDLE BECAME SPONGY AND AT TIMES VERY HARD TO DEPRESS. We had our Toyota dealer run a diagnostic scan of the vehicle and they determined the brake booster and brakebooster pump were defected. The car has 70,000 miles on it at this time, and we have owned the car for 10 years and 8 months. Toyota will not honor this Customer Support Program since we are 8 months beyond the expiration date. There was a RECALL number 13V235000 issued 06-05-13 for the same exact problem, with NO EXPIRATION DATE. However, Toyota says it does not apply to our car. This problem causes the power brakes to not work as power, only manual brakes (Hard to Push). They also become very soft and not responsive if the engine has not run since the last time the brakes were pushed. THIS IS A DANGEROUS SAFETY ISSUE! ! ! My question is, the problem was a big enough to have Toyota issue this 10 year "Customer Support Program" to prevent a hazardous situation from being on the road for 10 years, why is it not hazardous NOW 8 months later? We welcome any help you can provide.
I have a 2010 Toyota Prius. The ABS pump unit broke down while driving on the road. Suddenly the breaks were not functioning correctly. Breaks got squeeze. Apparently it's a common issue and Toyota had a program around it to fix it till Jan 2021. But I couldn't go fix it before coz the lights didn't show up. Now in Oct 2021 it's broken and is not covered. I don't know how a company gets to call such a safety issue as option and not a recall and get away with it. The vehicle has already been identified as having a bad part. How come the company does own up to it considering it's an important part of the breaking system.
