The hydraulic break pump system failed, causing my brakes to go out for a minimum of 10 seconds while I was driving. It put me and my passenger at risk for collision until they abruptly came back on but weren-??t working well. The vehicle has been inspected by toyota itself, and there were no warning lights until the system itself failed.

Brake booster and pump failing. Traction light, brake light, and ABS light all came on at once on February 23. 2025. I brought my car to a Toyota dealership the next day and paid for a diagnostic. I was told the brakes could give out at any time if I do not get the parts listed above replaced. This is a danger to me and to others on the road. I was told the parts would take a few days to get ordered and I was quoted $3490.60. I was informed that Toyota was repairing these for free if the problem occurred within 10 years of manufacturing (2023) or under 150,000 miles. Unfortunately it has been 12 years but my car is under 100,000 miles.

On 2/14/2025 I brought my 2013 prius into a third party mechanic because all the brake warning lights came on while driving. After inspection the mechanic informed me that there was a vehicle service bulletin about the brake booster and brake booster system that Toyota sent out in September 2020. It states that models made between 2012-2014 may exhibit a condition where the brake ABS and/or on track lights are on and it is caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. Toyota placed an extended warranty on the part. They state that if the vehicle had the abs light come on for this reason they would fix it if and only if it fell within 150,000 miles or ten years from the first driven part. I have been told if the issue is not addressed it could caused brake failure, the repair is upwards of $3000. I have contacted Toyota to open a case and will be taking the car to a Toyota dealership but Toyota is not taking any responsibility for the faulty part even when they know it is an issue because they say it fell outside of the extended warranty. I need Toyota to be held accountable and for not addressing a known issue with the their product. This is not an issue with wear and tear, it caused by a faulty part on their part and just because the issue became apparent after their cut off does not mean they are not liable. The car has 125,000 miles on it, I was never made aware that there was an issue with the part, received no communication until I brought it into a mechanic who researched it.

My car is at 89K total miles and last week I had three warning lights pop up on my dash (Traction control, brake, ABS) which indicates something wrong with the automatic break system. My car is under 100K miles and I purchased it used in 2016, under ten years ago, and this problem is way too early to happen in my make an model. I got a code read on the issue (C1391) which indicates that my ABS Actuator is leaking/broken, a major safety issue as it happened as I was driving. Again, this should not be typical as I only drive a few miles per day on average.

Brake booster replacement zjb code hust started to light up. Come to find out thhere was a problem that being refered to as a customer service notice or something and I'm being told Toyota will not cover the replacement because the timeframe has expired. If the light had come on two years ago they would have. I'm reading from others that they had the same problem and have heard of repairs costing upwards to $5000, that is crazy. Is this legal for them to do as it is a major manufactor problem effecting the braking of the car?

Hello, This is not only ridiculous but not unacceptable alert what Toyota did to customers under certain age of Prius 2010-15, Camry hybrid 2012-2014 and Avalon hybrid 2013-2015 They -??inspected-?? my vehicle at the dealership in 2020 during the recall but they did not replaced defective parts (master cylinder & brake booster pump) from Japan. In September I could easily crash my vehicle. This is dangerous for customers and drivers especially in Uber & Lyft. Headquarters should be easily informed by you about it I fixed and send receipts to lovely Toyota- Idiota but they reacted with no responsibility of reimbursement. [XXX] Thanks for your attention!

I was driving on the highway. All of a sudden abs light, brake light and traction control light came up on my screen. Car lost braking efficiency and I almost crashed into the vehicle in front of me. It was within inches from crash. Found out it was the brake booster and the brake booster pump. Both these parts had been under extended warranty by Toyota unbeknownst to me. Never received any warranty letter or anything from Toyota. I contacted them but since our car has more tha 150,000 miles and over 10 years old they will not cover

When the brake pedal is depressed, it occasionally emits a loud squeaking sound. I recently took the car to a nearby dealership (Ourisman Toyota in Chantilly, VA) for inspection, where the service advisor informed me that both the Brake Master Cylinder and the Hydraulic Brake Booster Pump require replacement. Here-??s the detailed diagnosis: 1) Hydraulic Brake Booster Pump: The master cylinder/brake booster assembly is leaking pressure internally and requires replacement. 2) Updated Booster Pump: The updated part for the booster pump requires it to be replaced in tandem with the new master cylinder. The repair cost was estimated about $3,700 The advisor warned that if this brake component fails while driving, it could cause the brakes to lock up, posing a significant safety risk. Despite this being a well-known issue among 2010-2015 Prius owners, Toyota has yet to initiate an official recall for this part.

Took car in for repair because all the warning lights are on. The repair shop quoted $1200 for Anti lock braking actuator system which is defective. This is a huge safety issue and a costly repair from Toyota.

The car has been making an intermittent buzzing sound that I now have had diagnosed as a failing Brake Booster Actuator. This part is integral to safely stopping the car. Though the actuator has apparently been failing for months, there have not been any DTCs associated with it. I now find that there was a Customer Support Program regarding this issue which has since expired. It is referred to as "Customer Support Program ZJB" and it refers to T-SB-0024-19. Had I been notified of this, I would have had the brake issue corrected before the program expired.

Brake Booster failed last February 2024 while driving. The mileage at that time was around 89,270. Found out there was customer service support program for this issue that run through 2023. Since I bought the car used from Honda of Capitola (2018), I didn-??t get any notification or unaware of this CSP. And the issue came out only this year. Had I know about this letter, I could have this inspected by Toyota. This is very unusual to have a brake booster failed with less than 100K. Called Toyota for assistance but they said I-??m passed the CSP service date. Paid $3343.22 to have the car fix last 3/27/24. There should be a recall of this problem as more and more Toyota owner are still having this same issue. Thank you.

While driving my brake light, ABS light, and traction(?) light all came on at once. The brake felt like it had resistance and I have to push it a lot harder than normal to stop. I took it to get a diagnostic ran and received the code C1391. After looking more up for this, this is a very known issue for Priuses and I was never made aware of it. This is a safety concern for all Prius drivers and nobody is made aware until it becomes an issue.
