2010 Toyota Prius brakes complaints
Page 5 of 66: complaints 101 to 130 of 1,945, newest first, as owners wrote them.
The contact owns a 2010 Toyota Prius. The contact stated while driving 45 MPH, there was an abnormal sound coming from the front driver’s side of the vehicle. The contact stated that the traction control, brakes, the Pre-Collision System (PCS), and the ABS warning lights were illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the brake actuator and the brake booster to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with the TSB: POL1803, however the vehicle was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 143,000.
To submit a claim to the federal safety agency 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.
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!
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
ABS pump booster failed. Hard to stop the vehicle. Almost had an incident. Trouble code C1391.
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
The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS warning light and two other unknown warning lights illuminated. The contact stated that the brake pedal went to the floorboard while depressed. Additionally, the contact stated that while self-inspecting the vehicle, he became aware that there was no brake fluid in the brake fluid reservoir. The contact stated that when the vehicle was self-inspected for a second time that same day, the brake fluid was full. The vehicle was taken to an independent mechanic, who informed the contact of an unknown recall for the brake booster. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 85,000.
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
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!
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 the federal safety agency 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 federal safety agency 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 the federal safety agency 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.
ABS system displayed airbag symbol displayed brake symbol displayed seat belts light flashing airbag system showing off. Toyota dealership is aware of the problem with the ABS system along with the items mentioned. accident could have been avoided contact if the ABS system was working. Airbags did not deploy. Advise Toyota corporation on 27 February 2023 file number 230-227-00 2210 in regards to the ABS they were also advised of the airbag symbol displayed in the seat belt fasten flashing on driver side when an individual is seated in the car and buckled in. Vehicle has not been inspected yet however on Monday 6th of March it will be inspected by copart, by the direction of the USAA insurance company.
The contact owns a 2010 Toyota Prius. The contact stated that while driving at various speeds, the vehicle started to hesitate. The ABS and traction control warning lights were illuminated. The contact stated that there was brake message displayed. During the failure the brake pedal had to be depressed twice before the vehicle responded. The vehicle was taken to the local Service Center who diagnosed that power brake booster and master cylinder needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the vehicle did not qualify for the Extended Warranty related to the failure. The local dealer was not yet contacted. The failure mileage was 135,000.
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 the federal safety agency 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 the federal safety agency 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.
