I was driving on a surface street at about 40 miles an hour and then the brakes suddenly don't work. You have to press on the brakes very hard to make them stop. All the safety warning lights were lit up on the dash. Took the car into the Toyota dealership and they said that there was a brake booster and pump customer support program but it's now expired so they won't fix it for free. The brake booster part is about $2000. I contacted Toyota Customer Service and asked them when they sent the notices out for this. They looked up our vin number and said that the notice was sent to the previous owner, since we bought the vehicle used from a Toyota dealer. Spoke to a Toyota supervisor from customer service and told them we never were notified to fix the brake booster. The supervisor said they will not pay for the repair. I think this should be a safety recall and Toyota needs to repair these parts. It's very dangerous to drive the car when the brakes fail to stop.

To whom it may consern, I avoided a situation that could have been a very serious or deadly accident when my vehicle had unusual issue with the vehicle breaking system while driving on the freeway today [XXX]. The vehicle would not stop while pressing on the break pedal and I was able to quickly maneuver the vehicle on the shoulder of the freeway and was able to avoid a deadly crash. Looked on the dash and noticed that ABS, Break, and Traction Control lights all lit up. I was scared for my life and the safety of others around me. The vehicle was towed to my residence since it happened around 10:30pm California time. Quickly did some researched online for any recall on nhtsa.gov website but unsuccessful with any recall regarding the breaking system. I also found out that it is a common problem that other owners have been/experienced with the same vehicle year, make and model. I would greatly appreciate for any information I can gather in order to assist me on how I can get Toyota to look into this issue for the safety of myself and others. It was a very scary scenario that could have been a tragic one that I found myself into. Looking for a prompt response to address this issue. Thank you!

Symptoms: The vehicle exhibits a constant and repetitive noise when the brake pedal is pressed. Additionally, multiple warning lights are illuminated on the dashboard, including the red brake light, yellow ABS light, yellow traction control light, and tire pressure light. Suspected Cause: The issue appears to be related to the brake actuator or accumulator. This may be associated with Diagnostic Trouble Code (DTC) C1391, indicating an abnormal leak in the accumulator. This problem causes the brake booster pump to run continuously to maintain pressure, leading to the warning lights and noise. Safety Concerns: The malfunctioning brake system components could compromise the vehicle's braking performance and overall safety. Purchase Details: The vehicle was purchased recently from a dealership, and the issue was not present at the time of purchase.

On our 2011 Toyota Prius there is a complete loss of breaking. The ABS, TCS, and brake lights all came on at one but went off after a few minutes. A few days later the entire system failed when the car was started and now there is no breaks at all on the car. A few months before we took the car to the dealership complaining about a noise when hitting the breaks and was told it was normal and to ignore it. It looks like Toyota knows about this issue and opened a customer care repair program but it expired in 2022 and was not advertised at all so the only way someone would know about it would be if they had an issue. Currently in order to fix the problem we are looking at around $3000 in parts and labor. Looking at other websites including this one the issues appears to be widespread.

I was driving the vehicle around 55 mph when a check hybrid system warning popped up. About 30 seconds later the vehicle went from being in drive to B (brake mode) and the vehicle began to slow at a rapid pace with no warning.

On April 28, 2024 I was driving when my brakes became squishy and my ABS warning light, red brakes warning light, and traction control light came on. I was very fortunate to be close to my destination and only traveling under 25mph. Roughly a week later it was driven approximately 150ft (on private property) and the brakes were very unresponsive. The car was never accelerated past 3mph for that move. The loss of braking was sudden and happened without any prior warnings. Had I been on a high traffic, high speed road, I believe it likely that this would have resulted in a catastrophic accident. The Master Cylinder Actuator Assembly and Brake Booster Pump Assembly failed. This was confirmed with OBD and a Snap-On Solus Ultra scanner. Both parts have been removed and are available for inspection upon request. They have not been inspected by anyone. I did contact Toyota about the braking issue and they did not express any interest in the issue or inspecting the failed parts. To make my Prius road safe and legal, I needed to replace the Master Cylinder Actuator Assembly and Brake Booster Pump Assembly. These parts were bought from Toyota, who has so far profited from my car's brake failure.

For the past 2 years I've had issues with the ABS, Traction, and Brake lights coming off and on on my dashboard of my 2011 Toyota Prius. Mechanics have replaced various things but have never been able to find the exact problem because the car doesn't either give any codes or it gives codes that don't really say what the exact problem is. I took it to a dealership again today, because not only are those 3 lights on but now the car is beeping continuously, and the dealership told me it was going to be over $5800 to fix the car, that's replacing the brake booster pump and the brake master cylinder, but the only code the car is showing is C1239, no other codes, C1239 is for the rear speed sensor LH. Every time I've had a mechanic/dealership look at the car, they can't find the exact issue and after replacing some parts, they tell me it could be the brake booster pump and the brake master cylinder, when I called toyota corporate about the warranty stuff to cover those being replaced because of the faulty issues that have apparently been acknowledged by toyota, toyota refuses to have the warranty work done, telling me that my car no longer qualifies for that warranty work, although I've never received anything from them talking about this issue in the past. I'm told now the beeping is those two items have completely failed and the car is now unsafe to drive, but it's the only vehicle I have to get to work, etc. The lights will come and go, but stay on more steady now with the beepi

As is the case with I am sure thousands of Toyota Prius owners, the brake actuator in my 2011 Prius has failed. The car has approximately 128,000 miles, but given that it is a 2011, the car is outside the Toyota 10 Year/150,000 warranty extension. The deals wants $3,200 to repair.

Driving yesterday on residential street, I gently applied my brakes to stop for a red light. The brakes did not stop the car; pumping the brakes did not help. Dashboard illuminated skidding car diagram, and BRAKE light went on. I took my foot off the gas, rode somewhat on the shoulder, and slowly found a place to park the car. Had to have it towed. No prior warning that the brakes would fail. Dealership advised it was a leak in the brake booster pump or actuator. Later learned that there had been a class action lawsuit dealing with this issue. Also that Toyota had extended the warranty when this happened frequently. I never got a recall notice about this. My car is a 2011 Prius with 59,000 miles. The extended warranty only went to 10 years, and mine is 11 years old, but I haven't seen anyone else in the chat boxes who had such a low mileage as mine. Thankfully neither I nor anyone was injured. But this is definitely a major safety issue and a very expensive repair. Over $3,000. What recourse do I have?

I bought this car new in 2011, and it is now driven by my daughter. The brakes started having problems around 2019, and the car was taken to Toyota service. It was thought to be a tire issue and the tires were replaced, but the brake issue remained. In February 2024, all the dashboard brake lights came on, and my daughter immediately took the car to Toyota service. The problem was a defective and leaking brake booster pump assembly, a defect well known to Toyota, and the subject of extended warranty on this model (10 years or 150,000 miles) and a recall by Toyota on some other models. Since it was after the 10 year period (despite reported problems during the 10 year period), corporate Toyota told the Toyota dealer service department and our family that they would not cover the $3500 repair bill incurred. This should have been a recall. I am horrified to think what could have happened to my daughter with defective brakes. Corporate Toyota is well aware of this defect. Even a Toyota dealer has previously reported it to the NHTSA. [XXX] . I request corporate Toyota pay for this repair and issue a recall for other unsuspecting drivers of these vehicles. This is a potentially lethal defect that needs a recall, not a post brake failure repair. I send my great thanks to you for investigating this.

The conditions listed in Toyota Customer Support Program ZJB for the brake booster and master cylinder occurred after the 10 year in service date on my vehicle. Brake, ABS, and Traction control warning lights turn on intermittently and when this happens brake response is poor and cruise control shuts off. When applying the brakes an audible tat tat tat sound can be heard from the front of the car that sounds like the ABS being triggered. You should have toyota recall impacted cars and fix the issue as outlined in the TSB and support campaign.

The 2011 Prius has an issue known to Toyota, in which the brake booster pump fails after an indiscriminate amount of time, leading to significant loss in braking ability and control. Toyota knows of this because they issues an extended warranty coverage for these vehicles and this issue, that did not extend beyond 10 years, or 150,000 miles, whichever comes first. [XXX] ) When I was driving my car down Highway [XXX] I lost braking control completely, with a series of constant beeping starting to emit from the braking system. Luckily through mashing the brake pedal and using ebrake I was able to get the car to slow down and pull off the highway. The brakes sporadically and randomly cut in and out with the power braking, leading to uncontrolled stopping power and jerky or inactive braking. There had been lights on the dash indicating the traction system or braking system had issues but these would frequently turn off and on and didn't result in a loss of braking ability or performance and had been there a couple months. Upon taking the vehicle to a Toyota Dealership (Charles Maund North Austin) I was told it was a C1391 error regarding a failure of the brake booster pump assembly and that it would need to be replaced and reprogrammed for about 3300 dollars. After looking online I saw there were many other people with this issue, all who were unable to fix this in the given 10 year frame.

While driving the car I had three lights turn on the dash simultaneously. The parking brake light, traction control light, and ABS light. The brakes worked but felt spongy and not as responsive as normal. I had it checked out and it has code C1391. The recommendation is to replace the brake booster pump. I was quoted over $2,000 for the repair. There was a Toyota Customer Support Program ZJB that addressed this exact issue. It expired two years ago, and I am now stuck with the repair costs. I believe Toyota should have notified me of this potential danger and/or inspected the vehicle. I meet all the requirements of the bulletin, but it has expired.

I have been experiencing intermittent brake issues with this car now for the last 50k miles. Sometimes the warning lights on the dash will activate, sometimes not when I am experiencing issues. the power assist is the problem. - it activates and then deactivates without warning instantaneously, while applying brakes or not. Sometimes when I am applying the brakes without the brake assist working, it will instantaneously start working without warning, causing my car to almost lock up its brakes. This is very dangerous, especially in traffic. When I apply my brakes at any given time, I never know if I am going to have power assist or not. I have replaced the brake master cylinder once already with a mobile mechanic and the problem went away for about one year but now it is happening again so this seems to be a reoccurring issue with this car. I have decided to just stop driving the car and bought a different one. I am a delivery courier and I cannot be driving a vehicle unsafe as this.

The ABS, anti-skid, and brake lights came on. Immediately, the brakes were less than full stopping power, and it was obvious it was not safe to drive the car any further. We had noticed that a pump was being activated when the brakes were being used, but no service codes were being displayed when checked. We later found out there was a recall on the Brake Booster and Accumulator, but it was only a limited recall, no notice was sent to us, and no repair was authorized by Toyota unless the brakes completely failed. Once the dash warning lights came on, the C1391 service code appeared when checked, "Abnormal Leak of ACC Pressure". This issue is a safety matter because your brakes fail instantaneously at any moment while driving.

Brake booster and brake booster pump assembly are faulty and failing. Brakes are still functioning, but will ultimately fail without warning, from what I have read. This is highly dangerous for myself and other motorists. I was driving last week and tried coming to a stop at an intersection. I pushed the brake pedal and the car hesitated and then jumped/lurched forward before coming to a complete stop. The brake booster is sounding every 30 to 45 seconds to try and build back the pressure it is losing. Toyota offered a "Customer Support Program" for these parts, as there's been numerous premature failures. Unfortunately, my vehicle no longer fits within the parameters of the support program (see attached). From what I've read though, Toyota has been negligent with replacing the brake booster under the support program. I have called Toyota Corporate and they have offered no reprieve and won't stand behind this faulty part. Toyota needs to be forced to recall these 3rd gen Priuses and ordered to replace the breaking system. Expecting customers to shell out between $2-3k to have the ability to safely break/stop their vehicle is ridiculous, especially when Toyota is more than aware of this issue. I was quoted $2600 over the phone to remedy the issue from an independent hybrid shop. I've owned 7 Toyotas and two have been Priuses. This 2011 is by far one of their worst to roll off the assembly line with numerous reports of breaking problems, oil consumption issues, and head gasket

No dealership in the area wants to honor it either. Instead, they want to charge me $3500.

Three lights appeared on the dashboard…code C1391. This has affected the braking system, and the traction control…and the brakes no longer regenerate the battery. The mechanic said “YOU MUST NOT DRIVE THIS CAR” until a $2,700 repair is made. There was, apparently, a service bulletin sent out in 2019, and was then extended until 2022…which we did not receive, although we’ve been at the same address since we bought the car. But our car did not develop this common issue until now…2023, and Toyota says it was not a safety recall, so they don’t need to fix it, or help us get it fixed. We believe it IS obviously a safety issue….since my brakes can go out at any moment.

When I pushed on brake pedal, the resistance was very soft for about 2 inches of pedal travel. At that point the brakes grabbed very quickly. I drove to the Toyota dealership (Huntington Beach Toyota) and was informed later that day that the master and pump master cylinder needed to be replaced. The dealer said that Toyota did have a program to replace these assemblies, but had not issued a recall, which (in my opinion) it should have. I've had quite a few cars, most of which lasted for more than 200,000 miles. I've never had such a failure nor have I heard of one. Clearly there was a manufacturing defect that should have required a recall.

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
