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.

My 2010 Prius has had lights come up on the dashboard. Vsc, brake, traction & ABS. After the local Toyota dealership ran diagnostics, it came to light that the brake assembly with accumulator will need to be replaced for near $5,000. It would seem that this is a common problem that has resulted in a recall for only some of the 2010 Prius models. Mine was not one of these recalled. I would like to request recognition that this should be covered under the same recall. Toyota is a good product, and I understand that recalls are just a part of life. As it stands, my regenerative braking no longer works and I have been informed that I will lose all braking eventually.

I was driving to my house and the brake pedal went to the bottom. Several lights appeared on the dashboard. I was driving in the highway and fortunately there was an exit and I could get out of the highway and I manage how to stop and I did not crash. The story could be another if I was driving faster. The next day I took it to the Toyota dealer and they told me that the problem was the booster pump (attached you can find the estimate). I was shocked when I found how much was going to cost me. My car has never had a problem and all oil changes had been at the same Toyota dealer. I have never taken the car anywhere else. Investigating I found that this model Prius 2010 in 2013 had a recall for this same problem affecting 82000 people. Unfortunately, the VIN number of my vehicle is not in this range that reaches A0067875 and mine is A0205005. I need for Toyota to extend the recall range because the problem is exactly the same and also help me to cover the cost of the repair. At this moment, my car is parked at home because is not drivable. I already spoke with Toyota headquarters and they said that they will not help me with the cost of the repair, it is really expensive and it is not my fault. Does Toyota have to wait until there is an accident" or injury or dead people"

Driving down the road when the brakes went out. Warranty coverage from Toyota on the same model, make, and year for this problem. My VIN not included in this coverage. The brake accuator assy is the issue. High dollar repair!!

I took my 2010 Prius in for airbag work & they asked how long I had been driving w/ my brake warning lights on. They had not been on prior to then. They hooked up a computer & showed me that the vehicle had been started 31 times since the warning was 1st detected. They said there was most likely a leak in the brake booster system. They reset the warning, I drove for a day & it came back on again while driving after about 10 starts. After the warning lights came on again, I noted an immediate & significant change in braking responsiveness & vehicle control...started pulling to the right. This was on the highway while driving straight. I took the car in to a local Toyota dealer for full diagnostic & they said that they're were unable to locate the exact leak location, but that their tech order shows to just replace the booster which will cost about $3,300 O replace.

Brake actuator failure. Complete loss of power brake function while driving vehicle on the highway. Currently a warranty enhancement letter covering this issue, but only up to 2009 model Prius, I have a 2010, not covered. This is a huge safety concern as it happened while driving with no indication of trouble beforehand.

No brakes. Brake pedal hard to press. C1256 code found. Several different lights on dashboard light up plus buzzer sound. Brake booster has gone bad. Recall on same model/make of vehicle. Believe part to be defective. Went from having brakes to little braking capability.

Several brake lights came on the dash while my wife was driving and the brake pedal had a different sensation. She said it still worked, but felt very different - enough that she would have thought something was wrong even if the lights hadn't come on. I took it to a local shop who said it had to go to dealership. Dealer wanted $3983 to repair saying that ABS accumulator was bad. In doing research I discovered that many Prius' were recalled, but unfortunately my VIN was not included in the recall. Also discovered that Toyota issued an "enhanced warranty program (ZG1) for models 2004-2009. But my newer model (2010) is not included in the enhanced warranty program. It feels like Toyota knows they have a problem, but are not standing behind their vehicles. I contacted Toyota corporate customer service and spoke with two different individuals who confirmed that because my VIN number did not match the recalls, there was nothing Toyota would do for me.

Serious brake issues! failure of brake booster and master cylinder causing impaired braking lending to safety issues. Many insiders at Toyota know the 2010 Prius brake issues exist and question why it is not handled at the corporate level. Brakes are spongy and additional pressure must be applied. The ABS is inoperable because of the problem. Please hold Toyota accountable for this chronic issue. The safety of all involved is affected due to inconsistent braking. My dealership asked corporate Toyota to address and they refused.

Brake booster failure.

- Deland, FL, USA

The brakes seem to disengage for a second at random times while pressing on them in a normal manor. I drive every day abut 20 miles and this seems to happen about once a month. I didn't think much of it until a few days ago when I had to slam on my breaks to try and avoid an accident. During that incident they disengaged for a second again. This was a second too long and I was unable to avoid a collision. I looked this up after my accident and I surprisingly saw similar reports on google for my car. But it looks like Toyota is saying that it doesn't affect my VIN number? I'm here to say that it does.

I drive a Toyota Prius 2010, I was driving when my brake, ABS, and traction control light came on at once. When I tried to apply the brake it would take a lot of force for my car to stop. I went to the Toyota dealership to get it checked out and they said part number C1391 has to be replaced. Tech found abnormal leak in accumulator. The accumulator pump assembly needs to be replaced. Which would cost me 2,000 dollars parts and labor. They also told me they might find out that the master cylinder might have to be replaced as well if damaged. Which would be 3,300 dollars. So worst case scenario it would be over 5,000 with tax to fix my car. I noticed other 2010 Prius models were recalled for the exact issue but only certain VIN numbers. My VIN number wasn't included. I feel like it should be if many other people are complaining about the same issue with this car. I can't afford over 2,000 in repairs let alone 5,000.

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.
