I having a problem with the brake booster on my Prius and the Toyota dealership I went to said I need to replace both the master cylinder and booster pump which would be 3000 dollars worth of parts and labor. After research this issue I have found serval people have the same issue. Also the parts are on back order, showing you how big of issue this is. The breaking system felt spongy, my traction control braking system and ABS lights came on. Thankfully I had just a couple of feet to my driveway.

When the brakes are applied and going over a rough road surface, or pothole, the brake warning light appears, and the brakes suddenly stop functioning until back on a smooth road surface. This happens all of the time under these conditions. It is really scary when the vehicle suddenly loses all braking while trying to stop. I have a 2012 Toyota Prius and a 2010 Toyota Prius. They both have the same problem with the ABS braking system. Cannot understand why this is not a full recall on this potentially dangerous condition.

The car has been suffering all of the brake symptoms for the recall of the 2010 Prius brake booster system. I've repeatedly complained about losing braking power when the ABS light comes on when I go over uneven surfaces such as railroad tracks or a pothole. The brakes have benn farting from day one while sitting at a light or parked if the brakes are depressed and then slightly released. And now today the ABS brakes are on with the battery light and there is limited braking power. I have to push almost all the way down before the brake engages. Toyota tells me I need to replace the brake booster system for $3500 and there are only 70,000 miles on my 2012 car. I feel my brakes have the same issues as the 2010 recall and more years including mine are affected and should be recalled.

The vehicle was traveling over 60 mph when the ABS, brake and traction lights came on and the brake became immediately spongy and I had to depressed even harder (past the foaminess) to reduce speed. A motor could be heard trying to turn over on the brake system. The car speed was reduced to 25-30 mph on the highway but the spongy brakes continued. Within 5 min I pulled off the highway and into a parking lot. Parked the car, turned it off and on to see if that would remedy the situation and nothing changed. I then called the Toyota dealership's service department to book an immediate appointment and arrived at the dealership approximately 40 minutes later. The car was looked at and I was told that the brake actuator was the issue and that they would like to contact Toyota to see if this was in warranty or part of the recall. I was told the next day that the cost of installation and parts would be at least $4,000 and that I would need to pay the full amount as Toyota was taking no responsibility. I called the Toyota customer service line, explained my situation and was told the same thing as I was told at the dealership. I feel that this brake actuator (its parts, its composition and/or its installation) is a systemic issue with Toyota products and a known issue with Toyota Prius' in 2009 and 2010. Tangential to this issue, my father owns a Toyota car as well and has also had to have his actuator replaced this year. Toyota should be held responsible for all faulty parts and installation and purchase of new parts. My maintenance record is exemplary and my driving record is as well so this is not regular wear and tear in my opinion.

I was traveling North on the highway. I was going between 50 and 55 mph when the traffic light turned to yellow and then to red. When I applied the breaks nothing happened. My vehicle actually appeared to speed up. I released the brake then pumped the break twice then again applied the break, this time stomping harder and with both feet. My vehicle did not stop or even slow. I went through the light, resulting in a car accident. I T boned another car.

Brakes failing, getting a C1391 code, leak in accumulator. Toyota has a warranty enhancement for this issue on the 2010 model but it has not extended to 2011 or 2012 models. I contacted local dealer and national representatives and was refused any assistance from Toyota. This issue happened twice over the last two days, both times while vehicle in motion on a city street. Warning lights came on and almost no stopping power.

A number of lights came on...ABS, anti skid, system failure, etc. The brakes started to feel very funny and started to make a strange noise. Took it to Toyota and they said it was not safe to drive because of the brakes. Needed the brake system (actuator is the name I believe).

The brake light, ABS light, traction control light all came on at once while driving normally. It did not affect the drivability of the vehicle. I took it to the local Toyota dealership to diagnose the problem. The service specialist said that this is a known problem with these cars and quoted a $2500 service price to replace it. If it is this known and this expensive to replace then it should be included in a recall. That would make it a design flaw by the manufacturer.

The ABS, traction control, and brake warning lights came on. I took the vehicle to my local Toyota dealership, where I was told the diagnostic has alarm dtc C1391 and this is a major brake hazard. The dealer state the ABS brake system need to be replaced at a cost of $4,504.63 plus taxes. I explained to the dealer the car is making a sound like the ABS is kicking in when it come to a stop. The noise persist coming in and out even when the car is parked and off. My 2012 Prius has only 74K miles. The brakes pedals feel weird and loose. I red Toyota extended the warranty for this issue due the brake actuator failure due manufactory issues. The dealer state my VIN is not there. What are they waiting to fix this issue on the 2012 Prius"?" we need to have Toyota fix this problem for all cars before catastrofic event happen.

When braking during normal driving conditions, a mixture of city and highway, the car makes a sound like the ABS is kicking in. When coming to a stop, the noise persists until releasing the brake pedal. Shortly after this started, the ABS, traction control, and brake warning lights came on. I took the vehicle to my local Toyota dealership where I was told it was the brake actuator needed replace at the cost of $3600. My 2012 Prius only has 76K miles on it.

Vehicle stability control, anti-lock brake, and traction control lights intermittently turn off. A few times it shut down the hybrid system and tell me to stop. Now all those lights are all on and I am driving without vss, ABS and traction control. Braking is getting harder. I took it to the dealer and they told me the cost is $3500. I did some research and found out that this is a known Prius problem problem

On July 28, 2017, I was driving along with my three children. I pulled into a driveway to park my vehicle behind a parked vehicle. There was approximately a 2 foot span between the back of the vehicle and the front of my 2012 Toyota Prius. To the right of the parked vehicle was a parked truck. Being that I was pulling into a space to park my vehicle, I was traveling extremely slowly. I began to press on my brake to park the vehicle and instantly knew there was a problem. Upon depressing the brake, several lights began to flash within the dash to include but not limited to the ABS, warning light, and the light with vehicle swerve lines. Other lights were also flashing, but I do not recall each one. The brake pad instantly went straight to the floor with no pressure. The vehicle would not stop and continued to travel forward with acceleration. To avoid hitting the vehicle in front of me I began to turn my wheel to the right. The vehicle continued to accelerate and came into contact with the truck that was to my front-right. My Prius failed to slow or stop. It continued to accelerate and began pushing the truck up the driveway and into the metal garage door with the brake pedal being depressed the entire time. Eventually, the car came to a stop and the lights continued to flash prior, during, and after the incident. After the car was towed tread wheel marks were found on the driveway where the wheels spun and left an imprint in the asphalt. I and my children were uninjured however, the incident was incredibly traumatic. The vehicle was deemed a total loss by my insurance company and as of yet to be processed for diagnostic testing by Toyota. The Toyota care service was informed of the accident. Toyota believes it to be associated with the intelligence component of the vehicle, however determination is currently unknown until diagnostic is performed.

While driving the vehicle on a dry surface street, the "check hybrid system" light illuminated. The brake pedal felt like I had to apply more pressure to stop and it seemed to travel further toward the floorboard than normal.

I received the warning, please check hybrid system. After checking the dtc the following code appeared on the computer: P0A08:DC/DC converter circuit status which indicates an inverter problem. Looking at the recall website using VIN number, showed no recall concerning this. The problem happened many times while driving on a city or a highway
