The brake booster assembly and brake booster pump have failed due to a vaccine leak internally in the brake booster. Failure of the brake booster can cause the vehicle to be more difficult to stop. Yes the failure codes have been reproduced. The vehicle falls -??out of warranty-?? for a part that should last the life of the vehicle. Replacement of the part is quoted over 4,000 dollars. The abs light, brake light, and traction control lights.

Hi I want submit issues with the master cylinder and abs pump assy I have 2 vehicles same model with average same mileage and both had issues with this system if I drove any distance below 25 mph in a constant time the dash lights comes on traction control, abs light, brake light, and the brake pedal goes low and barely brakes make this situation dangerous when I stop if you try turn it off the engine and on again lights stay there but if I reset the codes the pump works again for some while and then again when you don-??t expected lose pressure and I am really afraid for my safety and my family, and I am not the only one with this problem is too many Prius owners who have the issues I went from dealer and they advice $3000 dlls fix situation who motivate people to lose money for $1200 in parts and $1800 dlls in labor for something they can resolve it because in reality is an manufactured defect

Due to insufficient corrosion protection, the rear brake line of my 2010 Prius burst as I pressed the brake pedal in my driveway. It dumped ALL of the brake fluid onto the ground within a couple of minutes. Imagine if I had been driving!! There could have been a serious crash!! This was sudden. There were no brakes! Pedal lost all pressure and went to the floor when pressed. Lots of warning lights and alarms screaming inside car. The vehicle has been inspected and repaired at the Toyota dealer as of 10/03/2023. I have pictures of the failed part when it was installed on the car. If the dealer is contacted quickly, they might still have the actual failed brake line (which I was charged disposal fees for.) This was very scary and numerous lives could be at risk due to the popularity of this car and its use in rideshare/taxi service. There were no warnings prior to this. Brakes worked normally. Car is well maintained with dealer service records. There is no excuse for not properly trading such a critical part for corrosion, just to save money. Peoples lives are at stake!! It's the BRAKES of the car!! Someone needs to investigate this! I have pictures and receipts I can provide.

I was driving and all of the sudden lights came on, on the dashboard and when I started to slow down, I noticed the brakes were very "mushy" and barley worked. I then drove it directly to the dealership and on the way the lights went off, and brakes went back to normal. This is a very dangerous situation for anyone to be in and I don't know why NHTSA has not made this a mandatory recall for Toyota, I did find a recall # 13V235000 (which needs to be extended). The dealership said it would cost $3,000 to replace the Brake Booster Pump Assembly and Master Cylinder. This type of repair should be recalled, and NHTSA should get this resolved with Toyota ASAP.

Affected by the recall number 10V036000, the 2010 toyota prius is manufactured with a defective brake booster and master cylinder system which causes defect of the brake system, and causes my vehicle to often lose power in abs and randomly lose abs power braking, making brakes hard, and makes for longer stopping distance. This is a problem for many and obvious reasons on the road regarding safety. All vehicles should have optimal braking systems for the road, and should otherwise be repaired at no cost if the car is manufactured with defect. This has caused no accident for me yet but the abs has failed on many occasions. I have read at least 100 cases of this given vehicle under this recall being caused an accident with faulty brakes, and sometimes complete failure to stop which is extremely worrying. This recall excludes vin numbers past a certain date, yet the recall in question is certainly still affecting many cars, as capistrano toyota has also called for petition of toyota to repair at no cost for all affected vehicles. Yet all dealerships have denied my request and toyota has no formal coverage regarding the rest of the faulty vehicles they manufactured.

Hello on my 2010 Prius the ABS, Brake, Traction Control lights are all on lit up on my dashboard. Brakes are making loud noise when I stop the vehicle. I took the car into my local dealership service department. I-??m being told that the brake booster and master cylinder needs to be repaired. This was a part that was put under an extended warranty with Toyota but now it-??s no longer being covered by the warranty. So they want me to pay out of pocket to fix. I would like to report that they should honor the warranty agreement for my vehicle.

Brake booster failed while driving. Warning light ABS, traction control and brake light lights up. Lost power brake. Car is hard to stop with the manual brake in the fail safe mode. with C1391 code logged. Toyota had an ZJB warranty extension but my car is not covered because the warning light did not show during the 10 year window. The brake booster fail appear common and should be cover by a recall instead of a warranty extension.

There's existing problem right now in my vehicle that braking is less responsive and also the ABS, EMG brake lamps and Traction control lights are on the whole time on my dashboard. I took it to the mechanic and he found out that Theres a problem with the Brake Booster Pump Assembly which developed a crack inside the accumulator housing. As result nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. Under certain circumstances, this could affect stopping distance and increase the risk of a crash.

Even though a related recall has already been performed 4 years ago, my vehicle is exhibiting the same brake safety symptoms: - 3 dashboard lights all illuminated: BRAKE, ABS, and traction control (anti-slip) - brake accumulator pump noise occurring at 5 second intervals - regenerative braking and ABS are non-functioning - error code C1391 appears via OBDII The above symptoms appeared two weeks ago (6/14/2023), and on 6/16 an independent service center that specializes in foreign vehicles (including Toyota) confirmed the symptoms and error code, and said that the vehicle is unsafe to drive due to impending brake system failure. Toyota dealer indicated newer brake system parts are available to address the issue, but would need to be installed at my cost. The symptoms appeared while driving the vehicle at freeway speeds commuting to/from work. The vehicle is available to be inspected, however, I have already scheduled a repair (at my cost) because we use it daily for work.

The break booster started making a noise and my car should have fallen into the range of the previous recall for the exact part. I cant afford to change it so I continue to drive it and all of sudden the breaks are so hard to push and a constant buzz is going off! Autozone confirmed it was the break booster ans abs then a private shop did also

My ABS, break and anti-skid lights came on while my vehicle was parked. The ABS system shouldn't fail on a car. Many other 2010 Prius owners have reported the same problem. Toyota had break system recalls back in 2010 and 2013. I believe my car may should have been part of the recall, but was overlooked.

I took my vehicle to my mechanic at my independent service center because I experienced shaking/significant vibrating at 60 mph. I had also experienced a loud noise that only lasted about 2 miles. He found that the right rear brake unit, specifically the caliper, had seized. I contacted Toyota of America because there was no brake warning light to alert us of this situation. I received a call back from David from Sloane Toyota in Glenside, PA, who confirmed that the caliper seizing would not cause the brake warning light to appear. He also indicated that the caliper is not something that is routinely checked as part of state inspection, or the regular maintenance schedule. I am deeply concerned that this mechanical failure of the brake unit could have resulted in death(s). I request that Toyota vehicle owners and mechanics be alerted to this, specifically the fact that the brake warning light does not alert a driver of this brake part failure. Further, I request that an inspection of the calipers be included in the routine maintenance schedule and annual state inspection. Thank you for the work that you do to keep us safe!
