The contact owns a 2012 Toyota Prius V. The contact stated that while driving 65 MPH, brake fluid was leaking from the vehicle. While driving over 45 MPH, the brake pedal became firm, requiring the driver to exert extra force while depressing the brake pedal; the brakes failed to respond as intended. Additionally, a burning and toxic odor was present during the failure. Multiple warning lights illuminated on the instrument cluster, including the ABS system, parking brake, brake malfunction, and electronic stability warning lights. In addition, the automotive brake system, brake pump, and pressure warning messages were displayed. The vehicle was taken to a local dealer, where it was diagnosed with a failed brake booster assembly after inspection. The dealer determined that the brake booster assembly needed to be replaced. The contact associated the failure with Customer Support Program: 20TE07. The contact was referred to the federal safety agency Hotline by a lawyer, and the contact had found a class action lawsuit related to the failure. The failure mileage was approximately 187,000.

Brake actuator failure requires actuator and master cylinder replacement. All dash lights came on while driving. The vehicle was diagnosed at Brian Easler Toyota in Hendersonville North Carolina. The brakes are still operational temporarily but spongy and expected to fail so the car is not drivable. I expect to have the actuator and master cylinder replaced in then next few weeks at a cost of $5600. I see there were previous recalls on the braking system that have now expired.

Upon exiting the highway my brake system when engaged was completely unresponsive. I of course pushed down gently as would and upon realizing the brakes were not responding I started pounding on the brake pad. I had to ram the brake down for the vehicle to even slow. Thankfully no-one was in front of me at the light and I was able to pull into the nearest gas station having to ram brake to fullest extent to get the vehicle to stop moving. All lights within the braking system lit up including the Master Warning Light, Brake System Warning Light, ABS Warning light, and SLIP indicator as well as the warning siren. These warning lights did not come on til after* the brake system was engaged with failure*** NOT PRIOR. It was not indicative of an issue prior too, no former brake issue or warning lights. I turned the vehicle off and then back on again to see if the same lights still lit and issue was still malfunctioning. I called for a tow and had vehicle taken to the Adams Toyota Dealership (MO)The following diagnostic code C1391 was registered on my vehicle at dealership. Upon research (not disclosure) I found that the above code- C1391- "Brake booster and Brake Booster Pump Assembly" is a known issue that Toyota offered a Warranty repair from May 21-Nov 22' IF FAILURE Not a recall but a "if" brake system fails. Please see Customer Support Program 21TE01. I purchased vehicle in OCT 21 and was never informed, never provided this warranty letter, issue didn't show up on Carfax etc and I purchased directly from the Toyota Dealership. Upon research you will find that Toyota is currently in class action and individual lawsuits re this specific part failure with the above diagnostic code. They are denying replacement due the expired warranty time. The Parts should recalled* not just a "warranty issue" -unacceptable to leave buyers uninformed to such a major issue that can cause accident/death (IM PREGNANT I MAY ADD!) and unable to seek covered repairs unless it fails!

I purchased a 2013 Toyota Prius V a couple of years ago from a reputable local dealership. In July of 2024 my brakes failed and several lights came on the dashboard. I went to my regular mechanic, Mr Tire and and to Hendricks Toyota and got two estimates, both a shocking nearly $4000. This is for a BRAKE BOOSTER and ABS PUMP ASSEMBLY. I found out that this was a known issue for years by Toyota and dealers were sent a TSB regarding this. I called Toyota corporate and at at first was told that there was a recall on the parts, BUT that the period of repair by Toyota had closed in July of 2023, one year prior to my car's issues. The next time I called asking for upper level management (which I never got) I was told that it was not an actual recall, just a "special program" that has now ended. They basically figuratively shrugged shoulders and said oh well, sorry we know this is frustrating but you will just have to pay out of pocket. I am a [XXX] on fixed limited income. I don't have $4000+ available just like that. I work part-time providing concierge services for [XXX] 10-20+ years older than me who are no longer able to drive. I take them grocery and pharmacy shopping, and to doctors appointments etc. I bought this car specifically because it is a comfortable wagon perfect for me and my elderly clients, easy for them to get in and out, easy to place their walkers or folding wheelchairs in. I am so stressed, nervous and worried about this situation, as I know I am putting myself, my clients, and others on the road at risk every time I take this car on the road! Particularly now that we are getting wintery weather. I cannot comprehend how such a huge company as Toyota refuses to help with a dangerous defect that they are well aware of. I am sorely disappointed, as myself and my entire family have been loyal Toyota car owners for over 40 years.

Brake Actuator Valve Wear all lights relating to brakes are on, Dec. 12th 2024. The warranty for this expensive fix ended March, 2024 or 150k miles, there are only 106k miles on the vehicle. Something that is such a safety hazard SHOULD not have a date. We are experiencing unexpected loss of brake power while driving, accompanied by multiple dashboard warning lights, so we are unable to drive to the Toyota Dealership to have it scanned for issues. Toyota has advised us NOT to drive the vehicle, and we live 40 min from the nearest dealership. We bought the car from a Toyota dealership used, and they should have fixed this before selling the vehicle. Complete negligence and a huge safety issue. We only ask that they warranty be extended for the entire year of Dec. so that we can get this fixed asap.

About three weeks ago, my daughter told me that several lights were on on her display. I checked and among them were the traction control and 2 other related to the brake system. I looked up possible causes on the Internet and it seemed the brake booster/master cylinder could be a culprit, but then I checked the fluid reservoir and the fluid was low, so I topped it off, drove the car, pumped the brakes a few times and all the lights went off. About a week later the lights were back on. I checked all the lines and saw not visible signs of leaks and decided to take it to a mechanic. I took it to a local mechanic and I was told that the brake master cylinder with brake booster failed and had to be replaced. Afterward the brakes were repaired I went to 2 local Toyota dealerships to check the price of the parts. The first dealership provided the prices without any discussion. At the second dealership, the employee who waited on me, after I provided her the VIN and told her that I need the price of the brake booster/master cylinder,m told me that there was a service notice on the booster/master cylinder because of a high rate of failure and that I would have to check with the service department before she could sell me the part. This is concerning, if Toyota knew/knows that the part has a high rate of failure, why wasn't a recall notice issued?

The Brake Master Cylinder and Brake Booster pump failed to maintain pressure. I don't have the replaced parts, my mechanic recycled them before I realised I was going to submit this. When the part completely failed, I had the ABS, traction control lights on. I couldn't trust that the car wouldn't have a problem stopped, and the brake pedal also became squishy in responsiveness. My own safety, my kids safety, and the safety of others was at risk and I immediately stopped driving it to get the repair done. The problem was confirmed by a Toyota dealership and this was a recall but since my car is older the recall had expired. I was unaware of this recall until the issue began. It was also confirmed by my personal mechanic to be the failure. The Dashboard lit up the ABS, TCS, Brake, (!) light, VSC, and the sound of the pump changed. Before all the lights came up I had noticed a air leaking sound coming from near the brake pedal at times.

At approximately 150,100 miles (barely outside Toyota's extended warranty) several dash lights came on including the brake, ABS, and traction control lights. A Toyota dealer determined the problem to be the notorious C1391 brake booster issue (which seems identical to previous petition DP19-004). Even though by the time I got the vehicle to the dealer it had 150,300 miles on it (just 300 miles outside the extended warranty), Toyota refuses to pay a dime of the $4,000+ repair cost! I cannot afford the repair cost and since I was NOT warned that I could not drive the car as the brakes were still operational without the ABS, stability control, and traction control, I continued driving it. But after approximately 4 months, on 12/29/2023, at 152,787 miles, as I was slowly driving through a residential neighborhood, I lost almost all ability to brake and had to put tremendous pressure on the brake pedal to get the car to stop. Upon a subsequent reading of error codes that I performed myself, in addition to the C1391, codes C1252, C1253, and C1256 have also now triggered. It is a miracle I did not have an accident as I could have easily been on a highway or going down a steep hill when this brake failure occurred. In my 36 years of driving, I have never been behind the wheel of any car in which the brakes have failed like this, regardless of make, model, or year of vehicle. Please issue a recall on this known defective part before someone gets killed. (NOTE: I tried several times to upload the document receipt from the dealership with brake booster diagnosis but every time I click on the "Upload Files" button, the button disappears.)

Driving 2013 Prius V multiple lights suddenly came up on dash Brake System, ABS, Master Warning, SLIP indicator Safety put at severe risk while driving. These defective parts installed were never disclosed, or notified, by Toyota and put in severe risk for consumers to drive as a National Recall was NEVER issued. Toyota was called since this and refused to fix. Toyota acknowledges parts are defective yet refutes liability despite acknowledgment of defective parts. Defective parts never disclosed to me by any entity of Toyota including Dealerships/Corporate despite willful knowledge of national defective parts in model 2013 Prius V. This is a liable safety situation that can cause irreparable human life damage.

As my wife was driving my children to school All the lights on my 2013 Prius V dash came on as I was driving on December 2, 2022. All braking power became stiff and it was hard for me to stop. I pulled over turned off my car called AAA. When the AAA driver came to check out the vehicle she was surprised he told me “oh ya this is a common problem. He told me is most likely was the ABS master cylinder and brake boosters needing to be replaced. I would take it to Lithia Toyota of Missoula. A representative from BOSCH came to look at the vehicle made a special appointment for this person to meet me and my wife at my local Toyota dealership. They checked the car and told me there wasn’t a problem with my brakes. The Bosch representative said the car was fine. My wife and I would then leave and exactly one week my wife called me at work to say all the lights on the dash would came on again as she was driving. We would then take it back to Lithia Toyota for them to tell me it was the ABS braking system and I would need to spend $5000 to get the car repaired. Parts and labor. Her car is only worth 11500. They wanted me to spend more then half of what the car was worth. I would research and learn so many people are having this issue. There was a “customer support program that ended at the end of August 2022. This would be there way of weaseling themselves out of the issue. I am reporting this to help me and other drivers. Please don’t ignore. There are TOO MANY COMPLAINTS FOR YOU TO IGNORE. People have HAD MAJOR ACCIDENTS my wife and Children’s lives were at jeopardy due to your incompetence of over looking this issue.
