I noticed that my brakes felt mushy when applied. The ABS light came on in my car. I took it to 2 different Toyota dealers and both said that my break boosters were failing and would need replacing. I had 125,000 miles on my car. The brakes were working adequately at that time, but I was aware that they could fail at any time and put me in danger. I was charged $3637 for diagnosis and repair on 12/6/22.

The contact owns a 2010 Toyota Prius. The contact stated while his wife was driving 40 MPH, the traction control, ABS, brake warning light, and other unknown warning lights were illuminated. The contact's wife was able to drive to her residence. The contact stated that he was an independent mechanic and he had diagnosed that the failure was related to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The vehicle was towed to the dealer but was not diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 192,000.

The ABS, VSC/traction control, and brake system warning lights all came on at the same time in my 2010 Toyota Prius. I almost lost control of my car's braking ability. Afterwards, the hybrid system does not perform its regenerative braking/recharging any longer. And the cruise control mode doesn't work also. The DTC from the OBD2 port is C1391 - abnormal leak in the brake fluid accumulator. I found out that this issue is widespread among Gen 3 Priuses, but Toyota has not made this officially a recall campaign, but classifies it as a "customer support bulletin." But the issue is dangerous enough that it should be a recall item. I moved homes in fall of 2018, and Toyota says it mailed out a letter about this brake issue and resulting campaign, but I never received the letter. I was totally unaware that this was a safety issue, that Toyota acknowledged it, and that this safety issue with an ongoing "recall" campaign with an expiration date. Toyota denies that this is a recall issue, and will not provide this service. I would like for NHTSA to reopen and investigate this issue, and make Toyota issue a general recall campaign to resolve this dangerous safety problem with the car.

My 2010 Toyota Prius (JTDKN3DU3A1307523) had the ABS/brake warning/traction control (VSC) lights come on at the same time and I lost a significant portion of my braking ability, while driving. I was able to pull into a shop. The mechanic connected a code reader to the OBD II port and found the code DTC C1391. It is a failure with the ABS booster pump assembly and accumulator. I called Toyota corporate line and they said there was an expired Customer Support Bulletin, which I did not receive mail alert for, and that it is not a recall, and that the customer is on the hook for replacement of the failed component. They repeatedly told me it was not under recall, even though internet forums all mention it as a recall campaign. I called auto shops in my area (specializing in Toyota and Japanese makes) and they all did not want to perform the repair as they found it too complicated to do, and told me Toyota has a recall campaign and advised I call Toyota corporate to get serviced.

The brake cylinder and brake pump assemblies broke down in the middle of the highway. The ABS, brake, VSC, and traction lights lit up unexpectedly after ~1 hour of driving. I was able to get the car to the dealership and the service advisor noted that he was surprised that we made it as far as we did without a complete failure of the brake system. He advised that it was not even safe to drive the car around the corner for a few blocks because of the brake system malfunction. They provided an error code of C1391. This is a full failure of the brake system that makes the vehicle unsafe for street operation. This complaint adds to an already well-documented problem with these issues that Toyota acknowledged through a wholly inadequate "voluntary customer support program" which expired after the earlier of 10 years and 150,000 miles [link: https://bit.ly/3CntosU], which for all 2010 Priuses expired in 2021. The issue also appears similar to the ones reported in Defect Petitions DP19-004 and, indirectly, PE10006. This was also the subject of a lawsuit in 2020 that was since withdrawn by the plaintiff (Turner v. Toyota, Case No. 5:20-CV-00320, CD Cal). There are dozens of written reports and videos of people resetting their brake warning lights with paperclips. This is a major safety hazard for those 2010 Priuses that are still on the road and should be remedied by a recall.

My 2010 is covered under a recall. I had total brake failure and the dash light up like a Christmas tree. Brought in before the recall was released and it was repaired under my extended warranty. Then got recall notice, so I guess there was an internal fund transfer.

My 2010 Toyota Prius seemed to have a faulty ABS actuator/ boaster pump for years but I did not know it until recently. For years the car would display the abs, traction controls, and brake light for 50 miles and then go away but the most recent time it did not go off. The actuator continuously runs and you can hear it consistently buzz every 5-10 seconds. The brake pedal require a lot more force in order for the car to slow down and the car jumps forward when depressing the brakes suddenly. In the past the brake would require much more force but after a few miles on the road the light would go off and the car would seem to function as normal, but most recently as of last week the light would not go off and the brakes require a lot of force still after doing almost 400 miles. I had 2 near misses once almost hitting another car during a rainy day and another missing a stop sign by almost half a car length. I took my car to the dealership and they stated that the error code is showing a faulty abs actuator but the rep told me it should still be fine to drive if I do not want to pay the out of pocket cost and get it fixed immediately. This is a major safety concern for me and my family and even though I been servicing my car for year at the Toyota dealership it was never brought to my attention. Only recently when I had the near misses and had my mechanic run test on it did I realize. I then took my car to Toyota for routine maintenance and it was confirmed that the abs actuator/boaster pump was faulty, yet they offer no remedy and they never even notified me of this faulty OEM issue until I brought it to their attention. The dealership said my VIN did not qualify for any recall or customer satisfaction proposal (CSP) and that if I wish to fix the brakes/actuator issue it would be an out of pocket cost of a few thousand dollars. This is unacceptable and action needs to be taken immediately to recall and rectify this before innocent lives are lost due to brake failure.

Own a 2010 prius w 110k miles on it and now hearing brake booster buzzing every minute when car is on when im sure its not suppose to be going off that frequently. And of course I missed the recall date.

- Sebastian, FL, USA

I was driving my 2010 Toyota Prius and my car started beeping when I was driving when I tried to slow down the car was not able to stop the breaking system ABS started displaying and my car started to beep and it won-??t stop beeping. I did take my car to the dealer for a recalled inspection after my car broke down and I was no longer able to drive for my own safety. After I took the car to Downey Toyota for hybrid recall they didn-??t tell me anything but on the document they gave me it did state that the ABS was a problem. Now my car is still not able to be used because of my own safety concerns since the vehicle won-??t break when I put the brake pedal and a none stop beeping sound that won-??t stop at all.

The brake booster assembly and pump failed in my Prius. This causes the brakes to barely function. It disables both ABS and traction control. I nearly ended up running a red light and getting into a major collision with my three children in the car. The ABS, traction control, and BRAKE lights are all illuminated. Toyota advised they are aware this is a common failure but refuse to fix it. A dealership inspected it to confirm the flaw. Toyota will not fix it so I am forced to drive this vehicle with barely functioning brakes with my 3 children in the car still as I have no choice.

Brake booster actuator internal leak. Toyota refuses to cover the repair for the known defective and previously recalled part. See recall "D0H" and "customer support" campaign "ZJB" from Toyota. These are critical braking parts that control ABS, traction control, stability control, front/rear brake bias, regenerative braking and brake pedal feel and pressure. Loss of braking and all previously mentioned safety features occurs when the car sets the error codes, disabling and crippling the braking system. Longer stopping distances and much less responsive brake pedal is immediate. This part costs $700 from the dealer and they want over 2000 to fix the car due to the known defective, recalled part. This affects most Toyota hybrids of this era. The Prius is especially important to get recalled IMMEDIATELY, due to this being a common taxi and rideshare car, carrying multiple lives and heavier loads, in more severe operating conditions. Please look into this!! Toyota corporate has been called and they refuse to help or acknowledge the problem.

Brake, ABS and traction control warning lights went on when I was driving. I was able to brake but it was not functioning at 100%. The local mechanic was able to scan the code to get the C1391: Abnormal Leak of ACC PRESS error. The warning lights remain when I drive or parked. I no longer feel safe driving my vehicle. I plan to take my car to the Toyota dealer for further diagnosis and repair. I was informed that this is a very costly repair.

- Rutherford, NJ, USA

Brakes became soft the stopping distance grew.All my dash warning signs lit up. Why was my car to repaired in warranty or recalled when the problem was a manufacturer error? Toyota can't pick and chose which cars they will fix when they all have the same problem. I am attaching a 'Customer Support Program' sample and my car falls under the Primary Coverage section. My car was diagnosed at a dealership on 5/14/2021. But not fixed under warranty or recall. Toyota has recall on brakes for many of the newer cars too. Same issue.

- Hendersonville, TN, USA

My brakes are failing. The brake booster leaks. The stopping distance is greater. All the warning lights are on on the dash. Error code C1391 on the unit. Two dealers would not repair it under warranty or recall. They gave me a price of $2600-$2800.The situation still exists. The car has had the engine replaced out of warranty but by the dealer but the brakes were not replaced as a preventive measure.

I was driving my car with my daughter and was about to stop at the intersection and at that moment I realized that the car was not slowing down. ABS, Brake, and Traction control lights up on the dashboard. I was very scared and pressed the brake to the end and only then the car was able to stop. Further I found out that this is a very common problem for this model, but Toyota does not recognize this.

After descending a long mountain highway in our 2010 Toyota Prius and coming to a stop at the bottom the brake pedal travel suddenly increased, brake effectiveness decreased, and many dashboard lights suddenly came on including the brake system warning light and stability control system light. The next morning the dealer diagnosed a brake booster failure and prescribed replacement of the brake booster and master cylinder. Since this was a safety issue we had them do the work at a total cost to us of $3,363.93. They covered a rental car for us for only part of the repair period, which took 2 weeks.

While driving, left dash-light cluster and ABS triangle illuminated in-traffic with no visual pre-warning or audible alarm. Pedal pressed full force to bring car to stop and not plow vehicle in-front. Owners manual & internet suggests ABS & booster pump failure. Call to mechanic also suggests booster pump and ABS module as possible basis for trouble lights. Arranging transport to Prius specialty shop (not dealer) for further diagnose. No collision no injuries. Note. Full service brake rotors & pads completed 27-days earlier and only 671-miles driven since costing $946 paid. No issues discovered by reputable Prius shop as to noise, leak or visual other. R.
