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

I need a replacement of my Full booster brake pack and there have class action lawsuits associated with this exact problem.

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.

Getting a C1391 brake module /ABS failure

- Roswell, GA, USA

On the way home from a family vacation, the brake warning light, ABS warning, and swerve warning lit up on our 2013 Toyota Prius's dashboard. It was evening already, and with only a few miles to go we continued toward our home. While driving at approximately 50 mph, a red light appeared around a bend. I hit the brakes, a little hard, but certainly with enough time to safely stop. The brakes completely locked and the tired screeched and let off smoke, while the back of the car fishtailed around until we were sideways. It was terrifying. I believe the anti-lock brakes failed, and when they seized up it caused loss of control of the vehicle. Fortunately, no other vehicle was in the left turning lane, where we ended up, and we did not pass into the intersection. No one was hurt, but we could easily have been if not for good luck. I have noticed that the Toyota Prius has had a number of warning and warranty extensions due to brake actuator [XXX] ) and that several class-action lawsuits are underway. We would like to report our problem for the safety of others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

C1391 code at 148000 miles - just as others have reported. Quoted 3,500+ for the fix, Dealership said it was out of warranty and thus no help could be provided. The Code reads for a bad Brake Booster Assembly.

Brake actuator needs replaced. Yes please inspect. You have my permission for further review. My safety was put at risk since I was traveling 70-75 mph when my dashboard lit up with warnings. I tried braking and the brake was extremely hard to the touch and required a lot of force to even slow down and stop the car. Just making it home was dangerous. I almost ran into the garage wall since braking is extremely difficult and unresponsive. It hasn't been reproduced or confirmed yet with dealer or mechanic but everything suggests it's this from other accounts online. Toyota refuses to honor faulty part that is rampant in this generation model. The warning lights appeared as soon as it happened out of nowhere. All of these lit up on the dash all at once: brake, ABS, Skid, and the tire pressure icon. My car was making strange wheezing noises in the week or two prior to this happening. I think that is a symptom it will soon fail.

malfunctions of the brake booster and brake booster pump assemblies

Dashboard lights came on today, 8-9-24, indicating Brake Accuator Failure in my 2013 Prius. When I took my 2013 Prius to a dealership for service in April 2024 with mileage of 118,000, I informed them of the noise symptoms I experienced which apparently are a precursor to Brake Accuator failure. I even played them a video in which you can clearly hear these noise symptoms. I was not aware of this issue as I have never received correspondence from Toyota regarding this problem, although I now know a Warranty Enhancement Notification ZG-1 was supposedly sent out. I have not moved in 20 years and should have received this notice. Because the dashboard lights were not on at the time of the April 2024 service visit, and having no idea that the extended warranty window of under 150,000 miles or 10 years had closed on 12-31-23, the dealership would not even consider repairing the Brake Accuator issue. Even though this was a known issue by Toyota, and a dangerous safety issue, they will not provide unlimited free warranty repair. Add to that the prohibitive and unreasonable cost to repair this issue (anywhere from $2000 to $4000) for a car which is 10 years old, and for many is completely out of their monetary reach, is absurd. Even more importantly are the lives put in danger if the brakes go out while at high speed. Toyota should be forced to address this problem and resolve it immediately!

On August 3rd, 2024 my 2013 Toyota Prius lost power brakes at INTERSTATE SPEEDS. This put a number of lives, including my own, at risk. The computer program on the car appears to have been programmed to give operators a "death threat" by initiating a PROGRAMMED LOSS of power braking on the vehicle. There were a number of brake warning lights and an Audible Continuous beeping. When I moved over into the exit ramp from the interstate and applied my brakes this is when it was evident that power brakes were no longer available. I drove the car to a parking lot very close by and let it sit and checked my brake fluid but the brake fluid level was good. After this occurrence the power brakes returned to sufficient operation and have been in operation for approximately 2 days now with many display lights about brakes on the dash and the same audible beep is present. The brakes lights on the dash have been on since approximately November 2021 (2013 model car not even 10 years old of usage at that point). This is a safety risk that Toyota appears to have attempted to mitigate financial losses by having the customers that were not covered by their "customer care" program be the ones to pay exorbitantly high prices for the repair of this item in order to better balance and reduce their own financial loss for this mechanical problem. Toyota appears to have conscientiously reduced the number of cars that they offered to help repair financially under their customer care program. Their repair program went to 10 years since the date of first use or 150,000 miles, whichever comes first. It is unreasonable to expect that these cars will end their usage life at 150,000 miles and can be reasonably expected to be non-usable at that point. There are many vehicles that go past 150,000 miles of use and also past 10 years of use.
