To submit a claim to the NHTSA regarding my 2010 Toyota Prius (VIN [XXX] ), I wish to highlight a concerning issue with the brake booster, actuator, and brake booster pump assemblies. This malfunction has the potential to lead to brake failures, posing a significant risk of collisions with other vehicles. The presence of a diagnostic trouble code (C1391) and the illumination of ABS, traction control, and exclamation symbol lights, coupled with an audible whirring sound during braking, underscore the confirmed nature of this problem. This whirring sound initially emerged a year ago, accompanied by temporary dashboard light activation, which eventually subsided, while the whirring sound has persisted. Toyota has initiated an extended warranty program labeled (ZJB), encompassing a span of 10 years from the initial usage date or until 150,000 miles are reached, whichever comes first. Regrettably, my vehicle's mileage has exceeded 182,000 miles over the stipulated 150,000-mile threshold, and its age surpasses 13 years, rendering it ineligible for inclusion in this program. The actions of Toyota appear to prioritize financial gains over the well-being and security of countless drivers and passengers who are potentially endangered by these defective brakes. Their stance is exemplified by the reluctance to offer a comprehensive solution. I find myself compelled to bear the burden of approximately $3,000 in brake-related expenses at dealerships-?"an unjust imposition on consumers, given Toyota's distribution of flawed components that jeopardize safety and lives. Toyota's response has been inadequate, limited to extending warranties and performing repairs solely on vehicles that have already experienced brake failures. This approach neglects the prevention of potential injuries or fatalities that could be averted through proactive measures, such as issuing a full-scale recall. In light of these circumstances, I am seeking redress through the app INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.

My brakes are not working effectively. They are not engaging as they are meant to.

- Hedgesville, WV, USA

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.

Brake system failure. ABS light / Brake Light / Traction Control light. Low mileage car. Likely the last Hybrid I would buy. $4000 to fix. Almost what I paid for the vehicle. There is a recall but expired. Should be by mileage not time!

- Lafayette, LA, USA

Brakes take longer to apply with weird noise. There is a weird sound. Brakes are fine not worn. Mechanic says bad abs actuators which should not have failed since should last life of car. There was a recall on this but my car not in the vin search not sure why. All problems described in that recall is what I am experiencing.

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

- Elberton, GA, USA

ABS pump booster failed. Hard to stop the vehicle. Almost had an incident. Trouble code C1391.

- Ladson, SC, USA

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!

ABS brake booster failure. Vehicle with approximately 140,000 miles. Previous safety notice expired that covered 10 years or 150,000 miles

- Woodstock, GA, USA

The braking system developed a leak in the accumulator causing the whole braking system to fail and turn the abs light on in the car as it leaked brake fluid into the brake booster from the master cylinder

- Rancho Cucamonga, CA, USA

There was some kickback or resistance when engaging the brake to start the car. When the car turned on, the brake light, ABS light, and traction control light lit up. I took the car to Toyota service, they stated that the brake booster pump was defective and needs replacement. I see that there is not an open recall for this vehicle, however there was a recall #13V235000 that was sent out in 2013 with the exact same issue for 2010 Toyota Prius. We bought the car as a certified Pre Own in 2015, so we did not get this notification. I am trying to figure out why this car does not fall under the recall category? Thank you.

Almost caused a major accident. Brakes failed with no warning!

- Lafayette, LA, USA

My Prius 2010 has thrown the ABS, Traction, and Brake HUD lights all together. I took it to an Autozone and scanned the code to get the C1391: Abnormal Leak of ACC PRESS error. Many Prius 2010 have this issue, I'm sure I'll need to replace the actuator and/or accumulator and I know that will cost a good bit, i hope Toyota could help us fix it.

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 know why Toyota does not recall $$. They are now making $$ on parts and their dealers are making $$ on this service. I did not find a specific recall on the NHTSA website but I did find a recall # that I will be looking into in more depth. That recall number is 13V235000. The dealership said it would cost $3,000 to replace the Brake Booster Pump Assembly and Master Cylinder. If I were someone with very little funds to get this repaired then I would drive the car as my only source of transportation. This type of repair should be recalled and NHTSA should get this resolved with Toyota ASAP.

I was driving in my neighboorhood and as I went up the wall bridge my acceleration stalled and my ABS light, Check engine light, and check hybrid system light came on simultaneously and started beeping. At the same time, I lost my braking ability completely. I had to swerve off to the grass in the hopes of not hitting turning traffic at the stop sign. Luckily, it stopped before doing any major damage to anything. Thankfully, I was close to home and was able to put it in my driveway safely. The check engine light then cut itself off, but my brakes remained completely nonfunctional. If this had happened on the highway or a busy road I'm sure it would-??ve been much worse.

ABS system and traction control lost. ABS booster pump and master brake cylinder broke down. They should be life long parts. Brakes lost its function on highway and was pretty dangerous. ABS light, traction control light and brake light on. Dealer refused to change on their own.
