2010 TOYOTA PRIUS Service Brakes Problems

On November 25, 2025, at approximately 11:45 p.m., our 2010 Toyota Prius experienced a braking system malfunction during normal operation. The brake pedal required significantly increased effort and the vehicle exhibited reduced braking performance, indicating a loss of brake power assist. The vehicle required increased stopping distance, creating an immediate risk of a collision. At the time of the failure, multiple warning indicators illuminated simultaneously, including the brake system warning, ABS warning, check engine light, battery warning, steering warning, tire pressure warning, and vehicle stability control/slip indicator. There were no warning lamps or abnormal symptoms prior to the failure. The failure was determined to involve the brake booster pump assembly, a component responsible for maintaining hydraulic brake assist pressure. This component is known to experience internal accumulator housing degradation, which can allow nitrogen gas migration into the brake fluid and result in partial or complete loss of brake assist. The affected component remains available for inspection. Following the incident, an authorized Toyota dealership inspected the vehicle and reproduced and confirmed the condition. Service records indicate the brake booster pump assembly had previously been replaced under a Toyota safety recall. Despite this prior recall repair, the same component failed again after approximately 41,000 miles of service, demonstrating that the recall remedy was ineffective. As a result of this failure, the vehicle was rendered unsafe to operate. Despite dealer confirmation that the malfunction involved a previously recalled safety component, corrective repairs were declined, with warranty limitations cited rather than addressing the repeat safety-related failure.

Car keeps throwing a C1391 Abnormal Leak in Accumulator code. The ABS, traction control, and brake lights are all illuminated. Hissing sound from brake pedal. Spongy feel when braking and incredibly soft braking as well, very hazardous to driving and stopping. This is a known issue with the 2010-2015 Prius, and a quick internet search shows thousands of other Prius owners who also have this issue with their vehicles. It’s a safety hazard and can be potentially life threatening. Toyota is not doing anything to rectify this potentially fatal issue that impacts thousands of vehicles and vehicle owners and their families. Estimated cost of repair is upwards of $4,000 and simply not affordable to most consumers. Actions needs to be taken IMMEDIATELY by Toyota to recall these vehicles and fix them.

The contact owns 2010 Toyota Prius. The contact stated that while depressing the brake pedal, the ABS, brakes, and the vehicle stability control warning lights were illuminated. An Independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the brake booster and accumulator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in the recall; however, the recall had expired. The failure mileage was 172,000.

Mileage: 172,000

One day after arriving home from work, all the sudden my ABS light, BRAKE light and traction control light turned on, my brake pedal being harder to push, and my car making weird humming noises every 5 seconds. Upon taking my 2010 Prius to my trusted repair shop, it was revealed that my break actuator was faulty. I drive on roads that need this part to WORK! Especially in the height of construction going on PA. One of the roads that I take has been milled up and upon driving on that road I nearly swerved onto the side walk 3 times! My breaking has been harsh and with one incident that nearly didn't break in time at all! Doing research and looking into the active investigations on this part, it turns out I am one of possible thousands who are dealing with this issue that has all been tied back to the break actuator being faulty which is very expensive to even repair for something that is obviously a poor design.

The brake and pre collision system suddenly fail without warning.

Have multiple warning lamps that light up on and off and the brakes in my car get spongy making the braking unsafe. The lights that turn on are the steering/ traction , brake, and abs light. There are multiple complaints online on YouTube from similar issues ongoing and no recall made. My mechanic says it indicates a leak however there is no brake fluid missing and on YouTube there’s work arounds because people keep getting the same message, yet no recall has been made. This can affect steering and cause an accident. Please recall soon. Including YouTube link so you can see all the comments and issues from thousands that don’t know how to report but view to fix temporarily.

The ABS, Brake, TSC lights have all appeared on the dash. When running the OBD codes, the error C1391 appears indicating a problem with the ABS pump. When under the dash with the vehicle running, one can hear the abs pump engaging every few seconds which is not normal. After resetting the code. The error quickly pops back up. This is a known problem with this model Prius that Toyota is aware of. Toyota has NOT put out a safety recall for this issue. They refuse to make the repair of a faulty designed abs module, which is obviously a safety concern. The vehicle currently has 128000 miles with no other issues.

It is a known problem that Priuses manufactured from 2004 to 2015 have issues with the brake master cylinder and brake booster accumulator. When the vehicle computer recognizes an internal leak (ABS C1391) or other issue in the accumulator pump, it completely disables the regenerative braking system, which significantly reduces braking power. In my case, the problem is intermittent, and the vehicle computer will occasionally clear the code and operate normally. A slight whirring sound can still be heard (indicative of an internal leak), leading me to conclude that the part is still damaged, even when the code clears itself. This continues to affect my and my passengers' safety because the problem comes back with no warning while driving. Many times at highway speeds, the regenerative braking system will shut off while decelerating. This has caused scares and near-accidents. Imagine you are approaching stopped traffic while traveling 65 miles per hour. You press the brake to start slowing down, and while decelerating, the dashboard lights up and the brake pedal goes spongey. Now, you must slam the brake all the way into the firewall to engage the disks and pads exclusively. Aside from the imminent terror of hitting the car in front of you, now you are skidding on the brakes, worried the car behind you will crush the rear. Sooner or later this will cause somebody to get into an accident when a split-second decision cannot to be made quickly enough. The issue is well-known, and a warranty recall was issued, but it does not cover any vehicles over a certain age and mileage. It has been reproduced by my local mechanic and inspected by a Prius specialist, who both quote about $3800 to fully replace and recalibrate the failing parts. There were no indicators of this issue before it happened to my wife and I the first time on the highway. While I am grateful that nobody was injured, the situation could be completely different had the problem occurred just seconds later.

Brakes have failed with a DTC C1391 indicating an accumulator leak. The brake booster pump constantly runs. When the DTC is triggered the brake feel becomes suddenly different as regen braking is lost. Appears to be a very common and expensive repair. Toyota has already had recalls and extended repair program for these parts but they are now expired and not covered.

A few weeks ago, while waiting at a traffic light, the brake warning lights (ABS, Emergency brake, Traction control) lights on my 2013 Prius lit up and the brake pedal suddenly becomes much less responsive. I drove carefully back home, and researched online what the problem could be. To my surprise, this seems to be a known problem to Toyota, who had issued a campaign in the past to address this problem (ABS actuator, pump) and to replace the known faulty parts for free, but only for owners who were experiencing a failure at that time. Now the recall has expired, and owners like me who weren't having a problem at the time are stuck in a situation with cars that have a known, dangerous fault, while Toyota refuses to help with the problem anymore. The approximate cost for replace/repair is over $4000. All owners should have been included in the previous campaign, whether they were experiencing a failure or not, during that time period since Toyota knew that these parts are faulty.

What component or system failed or malfunctioned, and is it available for inspection upon request? Brake Actuator failed requiring replacement of booster assembly with master cylinder and booster pump assembly How was your safety or the safety of others put at risk? This greatly impacted braking and stopping distance Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, Toyota Dealership Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, Toyota Dealership Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. These lights appeared after the failure - Brake, ABS, Traction Control

While driving on the freeway the Traction control light, ABS light, Brake System Light and Brake light all came on. Fortunately I haven't had any issues but when I took it to the a dealership I was told that the Brake booster and pump need to be replaced as the master cylinder was leaking into the brake fluid and given an estimate of $3500 for the repair. People online have said that after having this issue the brakes can go out at any time. I am unable to pay for the repairs at the moment so I have to drive with the knowledge of having my brakes going out at any time.

Toyota issued a recall with a limited time for Prius brake booster/actuator failures. This issue is known to present brake failures and necessarily place drivers, passengers, and pedestrians at risk in the case of such brake failures. Toyota made no effort to proactively remedy this problem and further neglected customer safety by excluding Priuses with the same manufacturing issue from the recall, under its 10 year 150,000 mile requirement. Whether or not the Priuses have been driven 150,000 miles or 10 years the nature with which the malfunction presents represents a safety for any driver.

C1391 error, "Abnormal Leak of ACC PRESS". This is a common failure in many prius and requires the replacement of the brake master cylinder and brake accumulator. Toyota has an expired customer support program but no actual recall. Parts were replaced to bring braking system back into working condition.

I purchased a used 2010 Prius on May 1, 2025. On May 5, the car would not turn on. Thought it was the battery. Replaced the battery on May 6. On May 8, the battery was dead again. I jumped the car and tried driving it to the Toyota dealership to have it looked at. On the way a loud beeping sound started and the ABS light came on. I pulled over and noticed the brakes felt strange. After having it towed to Ourisman Toyota, the told me the brake booster was broken causing the battery to drain. The cost for repair is a little over $4,000. This almost half of what I paid for the vehicle.

Code diagnostic C1391 ABS system. I have replaced this in my previous 2009 Toyota Prius, it has been replaced in this 2010 Toyota Prius, and now needs to be replaced AGAIN in the 2010 Toyota Prius. It’s incredibly dangerous, no warning signs, spongy brakes all of the sudden that barely feel like they’re going to work. It puts not only myself in danger, but others especially when it just happens without warning and all of the lights come on as you are driving and the brakes become extremely wonky.

We have a 2010 Toyota Prius. All the sudden we got errors/warnings on our dash about ABS and traction lights, and brake light, staying on all the time. Brakes extremely sluggish, and from doing research advised not to drive it. Toyota did a diagnostic test which came up as C1391, bad ABS booster pump and master cylinder. This is a huge safety issue, others have reported brakes completely going out on the highway, and also reporting Toyota is not paying for fixing the issue, and only "certain Priuses" meet their criteria to pay for repairs. There supposedly was a recall at some point but we NEVER received it. I have contacted Toyota America and waiting to hear back. It is going to be very expensive to repair, about $3500-$4500. Yes, it is a 2010, but from what I'm reading and hearing is a MAJOR safety issue and Toyota needs to be held responsible and honor/extend any and all recalls. Again, I'm waiting to hear back from them, but was advised by many other Prius owners to file a complaint with NHTSA.

My brake booster master cylinder and pump assembly went out while driving on the freeway. My brakes became soft and unresponsive, though I was able to exit the freeway without incident. My ABS light, brake light, and traction control lights all came on. The lights have since remained on and my brakes continue to malfunction. My local repair show diagnoses the issue with the diagnostic trouble code: C1391 Back in 2018, before I owned the car, Toyota offered an "extended warranty" to have the parts replaced for free for 10 years or 150,000 miles, whichever came first. I'm past the year threshold but well short of the mileage one. I feel a recall should be made and the repair covered, as this is clearly a safety issue.

My ABS system light is on. The Toyota mechanic has determined that it is due to Nitrogen gas from a component of the brake booster pump assembly could leak into the brake fluid. As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash. Toyota recalled model year 2010 Prius vehicles manufactured March 31, 2009, through October 9, 2009. I took my Prius to Toyota to fix this ABS recall problems but they are refusing to fix the problem for free. They are charging me $4000 to fix it.

ABS, traction, and brake warning lights came on. No OBD code reading. Mechanic says needs brake booster pump; brake booster master cylinder. Theoretically mine were serviced but no way for me to actually verify it happened on the recall. Vehicle located in Kamuela, Hawaii.

- Brake system failure - Safety risk due to longer stopping distance - Problem was reproduced and confirmed by two repair shops - Components were inspected by repair shop - Several brake warning lights were ON on dashboard AFTER failure occurred. Toyota recalled 2010 Prius vehicles for Brake Booster and Brake Booster Pump assembly failures. Recall code D0H. Toyota claims that the replacement parts are fixed for the gasket leak issue. Toyota replaced these parts on my car in 2013 as part of the recall. The replaced parts labeling are verified to be the claimed fixed ones. But only about 62,000 miles after the D0H repairs (odometer at 81,400 miles) the parts failed again on March 20, 2015. I do not put many miles on my cars. Toyota has put a maximum repair date for this issue knowing failures keep re-occurring (No repairs supported after 2019). Toyota has not fixed this issue given the repeat failures. Repairs for this issue is extremely expensive at more than $4000 at independent shop (parts and labor)

I am writing to express my concern regarding an issue with the PCS System dash lights on my 2010 Toyota Prius. I recently became aware of problems related to the brake booster system, which I understand have been addressed through recalls or warranty extensions on certain models. I believe that the issue I am experiencing should be covered under warranty, and I kindly request your assistance in resolving this matter.

I drove the car to my destination without any issues. An hour later, when I restarted the vehicle to leave, the following dashboard lights were on (slip indicator, ABS warning light, and brake system warning light). When I drove the vehicle, the brakes had diminished stopping power. It took farther for the vehicle to come to a full stop when applying the brakes. When we had it checked by the Toyota dealer we were informed that there was an abnormal leak in the accumulator assembly (system diagnostic code C1391) and it would need brake booster/master cylinder assembly with accumulator pump replacement.

Brake booster, brake accuater went out even after the recall. Dealership said they could do nothing to help

While driving at a high speed in the left lane of a 2 lane interstate a car in the right lane merged into me. Luckily I was able to brake in time to avoid a collision, unfortunately the sudden braking at a high speed caused my car to loose all control. Upon braking my front tires lost all traction and shifted my car to the right, I remained horizontal sliding across the highway for an unrecognized distance (my guess is 10-20 meters), before shifting another 90 degrees to the right leaving me backwards. At this point I had shifted across both lanes and the emergency lane, I was backwards in a grass border on the right side of the interstate. If this had been any other sort of barrier I may not have Lived. This incident has not been reproduced or confirmed by a dealer or independent service center. The vehicle had recently had its worn brake components replaced in response to a similar incident happening, which I first attributed to worn brakes— this theory was supported by the brake technician prior to service. I have had a tire pressure light on since I purchased the car, but this was explained to me as a malfunctioned TPS.

Dear NHTSA Team, I am filing a safety complaint regarding my 2010 Toyota Prius (VIN: [XXX] ) due to ongoing brake system failures. My vehicle is affected by Safety Recall D0H (Brake Booster Pump Assembly – Accumulator), but Toyota refuses to replace all necessary components for a proper repair. Issue Summary: •My brakes have intermittently failed, requiring excessive pedal pressure and causing delayed stopping, putting me at serious risk. •I took my car to Toyota on Edens for the recall repair, where Service Advisor David confirmed that the brake booster and accumulator should be replaced together. •However, Toyota will only cover the accumulator under Recall D0H, despite the brake booster being critical for safety. •My vehicle has Diagnostic Trouble Code (DTC) C1391, indicating an internal leak in the braking system, but Toyota refuses to cover the booster replacement. Toyota’s Response: •I contacted Jessica from Toyota’s Customer Experience Center (Case Number: [XXX]). •Toyota refuses to replace the booster under the recall, leaving me responsible for the cost, even though the dealership confirmed it’s necessary. •This decision leaves my car in an unsafe condition even after the recall repair. Request for NHTSA Action: 1.Investigate the safety risks related to this recall and the necessity of replacing both the booster and accumulator together. 2.Ensure Toyota properly covers all necessary brake repairs for affected vehicles. 3.Expand or modify Recall D0H to include the brake booster, as it directly affects braking performance. I urge NHTSA to take action before this defect leads to accidents or injuries. I am available to provide additional information as needed. Thank you for your time and attention to this urgent matter. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Abs lights on, traction light on .Actuator running cicle constantly . Breaks felt spongy

Break booster fail. Will cause the breaks to fail. There was a voluntary recall on these but I never recieveed the letter in the mail. Thr break booster failed after the voluntary recall was up. Toyota said they cannot help with this. Other prius owners i talked to have the same issue with their 2010 prius break boosters and also did not get the letter in the mail.

ABS Pump/Motor failed. Lost power and control over the breaks . ABS light on

My car, a 2010 Toyota Prius, Level V has about 161,000 miles on it, and I have driven about 140K of those miles over the last 13 years. I have traveled around the DC/Maryland area and also taken the car on long trips. The car has been reliable, safe, and predictable... EXCEPT in one place/instance. I have probably driven a dozen times or more to the BWI airport from my home in Chevy Chase. On the return drive on [XXX], as I drive towards an overpass that is just before the [XXX] exit, my Prius goes into "Emergency Approaching Collision" mode. The brakes automatically forcibly apply, the seatbelt/lap harness grab me, and there is an emergency beeping from the system. The first time this happened... probably 10 years ago, it was very startling. My car was traveling about 60-65 mph. Luckily, there were no cars behind me... and I remained calm enough not to overreact. I was so startled that I needed to pull over to regain my composure. In one of the numerous other cases on this happening, my wife was in the car and she basically wanted me to sell the car because she felt it was unsafe. Because I am aware of the situation with my car, I always am cautious when I am driving towards the [XXX] exit. I drive slower, watch carefully for surrounding vehicles beside or behind me. But even yesterday, I was driving very slowly (approximately 35 mph). While I did not feel the system take aggressive avoidance/safety actions, still the warning beeps did take place... a little unnerving, but I had come to expect a problem at that site. In any event, I did want to bring the matter to your agency. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Twice while I was driving on the highway, my ABS and brake light came on, and my brakes became less sensitive to pressure. That is to say, it took more effort and I had to push my brakes further towards the floor in order for them to respond. I went to an independent mechanic and got the code C1391 which indicates a brake pump accumulator issue. I went to a Toyota dealership and and had the car inspected. They confirmed the C1391 code and said the brake booster assy with master cylinder pump assy was malfunctioning. However, I was never told by Toyota that this issue meant my brakes could fail at any time. My safety and the safety of others was put at risk because my brakes spontaneously became less responsive, my stopping distance was increased, and they were at risk of spontaneous failure.

I was coming to an intersection where two cars were waiting for a right turn. I pressed on the brakes and nothing happened. The car continued to move without slowing down. The brakes felt "blocked" and unresponsive. I engaged the manual break at the last moment and that slowed me down. But I still hit the car in front of me which in turn hit another car in front of it. The police report says "following too close". But I was not following other cars. The two cars were already at the intersection. I was just coming to this intersection and attempted to slow down as usual. Except that the brakes did not respond. My car was a total loss.

I recently had an issue with the brake actuator on my 2010 Toyota Prius, showing error code C1391. This caused reduced braking efficiency, and research shows it’s a common safety concern with Priuses. While there was a recall, it has expired, leaving owners like me without support. I kindly request an investigation to address this critical issue for the safety of all affected drivers.

Please read the attached file "prius complaint signed" for a full description. I am the owner of a 2010 Toyota Prius, 2ZR-FXE. The warning light came up on my dashboard of my vehicle, so I took my 2010 prius to AutoZone, to get a free diagnostic. The diagnostic indicated the problem code of “C1256” “Accumulator Low Pressure” for the “Anti-Lock Brake System.” See Ex. A (AutoZone Diagnostic). It is available for inspection. According to the safety recall number “D0H”, 2010 prius model “2ZR-FXE” has a “Brake Booster Pump Assembly which can develop a crack inside the accumulator housing. If this occurs 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.” (Emphasis added). I have noticed that when I brake hard, IT TAKES LONGER TO COME TO A STOP, WHICH THREATENS NOT ONLY MY LIFE, BUT THE LIVES OF MY WIFE AND TWO [XXX] DAUGHTERS WHO ALSO RIDE IN THIS VEHICLE. According to the safety recall, “Toyota dealers will perform an inspection and, if necessary, replace the Brake Booster Pump Assembly at NO CHARGE to the vehicle owner . . .” See id. The safety recall does not explicitly permit dealers or servicers to charge for an inspection with regards to this defect, according to the information provided me. The estimate, provided by DARCARS recommending replacement of the “BRAKE BOOSTER WITH MASTER CYLINDER WITH PUMP[,]” confirms that the issue appears to be that which is covered by the safety recall. Ex. F.; see also Exhibit B Safety Recall (The vehicle has a “BRAKE BOOSTER PUMP ASSEMBLY WHICH CAN DEVELOP A CRACK INSIDE THE ACCUMULATOR HOUSING . . .”). See also Exhibit E Error Code from DARCARS (“C1256 Accumulator Low Pressure”). Nevertheless, DARCARS refused to waive the diagnostic fee of $150 and would not repair the vehicle unless I paid them “$5,150.” See Exhibit F.

My brakes stopped braking but luckily I could drive slowly into a curb in my neighborhood. God knows what could’ve happened if I was on the freeway. All the dash lights came on at the same time so I ran some codes; it came back C1391 - the brake actuator is broken. Toyota will not cover it despite this being a very common issue. My car is undriveable until this gets fixed because it will not break.

The contact owns a 2010 Toyota Prius. The contact stated while driving approximately 40 MPH and depressing the brake pedal, the brake pedal was stiff and required excessive force to depress. The contact stated that the ABS, Stabili-trac, and Parking Brake warning light was illuminated. Additionally, the contact stated that a chime sounded and could not be turned off. The contact stated that the failure had been intermittent but was a recurring failure. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes). The manufacturer was not informed of the failure. The failure mileage was approximately 77,000.

Mileage: 77,000

hope this message finds you well. I am reaching out regarding a potential recall issue with my 2010 Toyota Prius. The vehicle's VIN is [XXX] , and I am currently located in the Austin area. Recently, my vehicle has been experiencing problems related to the brake system, specifically the brake booster pump assembly. The diagnostic results returned codes C1241, C1391, and C2300, which point to issues such as abnormal leaks in the accumulator pressure and actuator system malfunctions. Given that this issue may fall under a recall or extended warranty for the brake booster pump assembly, I would appreciate it if you could confirm whether my vehicle qualifies for this service. If it does, I would like to schedule an appointment to bring my car into the nearest authorized service center to have the necessary parts replaced. Please let me know if any additional information is needed. I look forward to your response and would greatly appreciate your assistance in resolving this matter as soon as possible. Thank you for your time and support. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Toyota failure to honor recall. See correspondence below for NHTSA ID and other detail. NTHSA Recall ID: 13V235000 Toyota Case#: [XXX] Very dissatisfied with Mr. Lxxxx's denial of our inclusion in the customer support program. He seemed to reach for every imaginable escape hatch to say "no". Claiming 2 notices were sent out (to the correct address) between December 2017 and March 2018, neither of which reached me, is dubious to say the least. The likelihood of our remaining a Toyota "family" with the eventual replacement of our 3 vehicles (including a previously unmentioned 2017 Rav4) has shrunk considerably. Shame on Toyota North America. ---------------------------------------------------------- (earlier Monday, October 21, 2024 at 11:31:54 PM EDT) Dear Mr. Oxxxxx: I’m writing to express my distress at being disqualified for this expensive safety recall about which I was never notified by mail and, despite receiving maintenance and inspections at the dealership in slim 2-year period between the mailer and the expiration, was not notified of the recall. The phone agent, Ms. Xxxxxx, was very courteous, opened the case, and informed me of the 2018 mailing about the recall, which I did not receive. I’m quite diligent about recall notices, we are a Toyota “family” with a Sienna in addition to the 2010 Prius, and records will show we’ve always attended to recalls for which we’ve been notified, going all the way back to our first purchase of a new Camry in 1997.

In August of 2024, my 2010 Prius with less than 100,000 miles - all the brake warning lights on the dash suddenly came on - without any prior warning. The brakes felt a little "funny" at the time, so I took it to my mechanic immediately because my safety or the safety of other was at risk if the brakes completely failed. My mechanic informed me that there was a TSB for the brake booster with master cylinder and brake booster pumps that Toyota new about. I felt that it was imperative that this was repaired immediately. Apparently Toyota knew about this issue but did not notify me in any way at any time. I bought this Prius new and have had regular service check ups. I had to pay nearly $5,000.00 to have this repaired which I feel that Toyota should reimburse me, and any others who had this problem.

ABS and brake lights lit at around 141000 miles code C1391 came up during diagnosis.

Brakes started making a hissing sound a couple of weeks ago. Yesterday evening when I was driving on freeway , I got an assortment of lights on my dash while driving . ABS was instantly disabled and it was significantly harder to brake the car. BRAKE light on dashboard came on. Traction control light came on . It was very dangerous and it was mere luck that there was no car in the front - otherwise I could have crashed. Pulled over to the side on the freeway and then came in internal roads to my destination , keeping a lot of braking distance and at slow speed. Turns out this is the infamous brake booster leak that was so bad Toyota was forced to create an extended warranty program on Gen 3 to fix it. Brought it to dealer next day. Got an estimate for $4000 for "REPLACE BRAKE BOOSTER AND MASTER CYLINDER(DUE TO INTERNAL LEAK)"

The contact owns a 2010 Toyota Prius. The contact stated that while driving at various speeds and the brake pedal depressed, the vehicle lunged forward. On a most recent occasion, the contact was attempting to park the vehicle and after shifting into the park position, the vehicle lunged forward as the brake pedal was depressed causing a minor collision with a curb and another vehicle. The contact mentioned the brake pedal required excessive force in order to come to a stop and that there was an abnormal noise present. The contact was concerned that the failure would progress causing a severe accident. A police report was not filed and there were no injuries sustained. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS System failed and advised the vehicle be taken to a dealer. The vehicle was not repaired. A dealer was not contacted. The manufacturer was not notified of the failure. The failure mileage was not available.

Heading westbound on I-70, taking Exit 29 off ramp from highway, I drove over uneven pavement. My traction control, ABS and brake lights illuminated, the brakes suddenly felt mushy. As I approached the stoplight at the end of the exit ramp, I questioned whether I would be able to stop. Scared me immensely. Luckily no cars were near me. I now do not have ABS, Traction Control, stability control OR regenerative braking.

Toyota refuses to cover a recall that I was never made aware of. My Prius need to have ABS Brake Accumulator and other components replaced. My VIN I was told had a recall but I was never made aware. I was told it may not be safe to drive my car. Toyota told me I would have to cover all cost for the repair and for my family that is just not possible. For the safety of my family, I am hoping NHTSA can help me in anyway.

NHTSA CAMPAIGN ID: 13V235000 Toyota will notify owners, and dealers will replace the affected brake booster pump assemblies. The recall is expected to begin late July 2013. Owners may contact Toyota at 1-800-331-4331. Toyota is no longer honoring this recall. They think it is acceptable for me to drive around with unsafe and defective brakes.

In 2015 I purchased my Toyota Prius in VA. I now live in Indiana and had my car checked for a possible sensor issue because the traction, brake & abs light were coming on and off. The diagnostic showed a brake accumulator leak malfunction. I contacted Toyota dealership once I was told there was a recall. The dealership said that it was showing it was replaced in 2013 from the previous owner in VA. It was listed then as a recall. I contacted Toyota Corporate and they said that it went from a recall to customer support with a maximum of 150,000 miles. I did not have any more problems until just recent. My argument is once a recall it should still be repaired. The part appears to be the problem. It is a safety issue and I need Toyota to fix the problem. Thank you!

The car suddenly threw a C1391 code yesterday with no previous warning. The traction, parking brake, brake system, and ABS lights are all lit on the dashboard. As this vehicle is my daily commuting vehicle, I must have the costly repairs performed, which are estimated at roughly $2,400. I will ask to retain the parts for inspection. The brakes are softer, and the breaking distance required has increased by approximately fifteen feet.

The ABS Pump( Accumulator and booster) are regularly failing on all Toyota Prius( 2010-2015). When the ABS pump starts to fail, the warning lights for Traction control, Brake and ABS come on. These lights come on at all speeds and its very hard to bring the vehicle to a complete stop when this happens. The brakes completely stop working and the brakes become rock solid. The brakes become so hard that they can’t be possibly be depressed to stop in time. I nearly missed getting killed from this as I am out of country and Toyota is refusing to fix it since its not a recall and I am in Canada. Toyota is asking $3500 in parts and $1500 in labor to repair. I can not afford it and this issue is on all Prius from 2010-2015. This is a major safety hazard and can cause serious injury and damage. Toyota is refusing to repair it since they believe the cars are out of warranty. However Toyota has been notified about this safety hazard arising on all Prius(2010-2015) but decline to respond or take action. I urge NHTSA to take action and get this resolved as the ABS brakes failing on the Prius can be really dangerous and can cause life threatening accidents.

The contact owns a 2010 Toyota Prius. The contact stated while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. In addition, the contact stated that several unknown warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with brake system failure. The contact was informed that the braking system needed to be replaced. The vehicle was not repaired. The contact was advised to take the vehicle to the dealer for service. The contact was made aware of Customer Satisfaction Program: C1391. The vehicle was taken to the dealer where the vehicle was diagnosed with brake system failure. The contact was informed that the braking system needed to be replaced. The contact was informed that the repair was not covered under the Customer Satisfaction Program: C1391, because the mileage had been exceeded. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 166,000.

ABS Lights turned on and need replacement. This is my 3rd Prius that have the Issue.

The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal would depress to the floorboard initially without warning. Over time, the brake pedal had become stiff upon depression with several warning lights illuminated on the instrument panel. The vehicle was taken to an independent mechanic where a code reader confirmed a defect with the braking system. The vehicle was then taken to another independent mechanic where the vehicle was diagnosed with a defective brake booster. The mechanic then informed the contact of NHTSA Campaign Number: 13V235000 (Service Brakes) which was linked to the failure. The dealer was notified of the failure and informed the contact that the vehicle was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 153,000.

Prius Gen III has a known defect with failing Brake booster parts. In Nov 2023, while driving my 2010 Prius (~160K miles), suddenly brake, ABS, Traction control, skid indicator lights popped up on the dashboard and I have lost the ability to brake effectively. There was a brake pressure loss and I had to slam hard the brakes to slow the car. The error code was 'C1391' and the mechanic diagnosed it as failure of Brake booster parts ABS Brake booster pump (accumulator) - part#47070 47060 and Brake master cylinder (actuator), part#47050-47140 and he replaced both these parts. Toyota is aware of these failures which are very frequent and hence they issued a brake booster “customer service program” ZJB - which extended the warranty for these parts. But many of us were not covered by this warranty either because of the time or mileage restrictions. This was a costly repair and we had to fix it out of pocket at the cost of ~$3000 as this is safety hazard without proper braking. To make matters worse, 3 months after the repair, the newly installed parts failed again and I had to go through the same repair. I called to Toyota to complain about this and they cannot do anything about it and advised me to report it to NHTSA.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at 55 MPH, with the brake pedal was depressed and went to the floorboard. The contact stated that the brakes failed to adequately slow the vehicle. The ABS warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the brake booster. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 120,000.

My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.

Brake booster assembly failure. Code C1391 - accumulator pressure leak. Toyota previously agreed to extend the warranty on this part on this year of Toyota Prius due to the known issue and the time limit for this repair was set to be in 2019. Toyota agreed to replace the unit only if it fails before that timeframe. My Toyota got recently affected by this issue resulting in over $3,000 estimate for a repair as Toyota no longer covers this repair for my vehicle. That’s a known issue with this part, Toyota knows it’s faulty and yet no recall has been issued. Now I have to pay for a repair out of pocket. I can’t drive the vehicle until it’s fixed. This should be handled as a recall with all faulty units being replaced regardless of millage. A few people opened lawsuits on this issue before and some got a settlement. I believe there is enough evidence that this should be classified as a recall and a free of charge repair should be provided to the owners. The brake booster unit has been buzzing a lot for quite a few months ( due to the pressure leak it had to work more than normal). Now it completely failed with the leak being so excessive that the brakes are very soft.

I’m encountering multiple dash lights with the brakes being very unreliable and no that’s no regenerative breaking. I checked with an obd2 kit and the app shows that I have a code C1391.

Faulty brake boosters that crack and leak, making brakes unusable and draining the battery (diagnostic code C1391). There was a Toyota service repair where they exchanged the faulty brake boosters with properly working ones, but it has lapsed.

[XXX] We took in 2010 Prius to Toyota Dealership in Pharr Texas because road hazard light, ABS , Brake and low tire alarm came on while driving car. They ran diagnostic and found out that the brake pump assembly and brake cylinder assembly has to be replaced. We called Toyota Cooperate to ask for assistance to pay for cost and after 4 weeks of reviewing issue they said they could not help us because the CSP had expired. This car was given to us by a friend of ours and they had not used it for 2-3 years so we got it we repaired and got car running again. After we drove it we came across this problem with the brakes. This car was was built in the same plant as the other recalled cars going by by the vehicle number . We believe that the CSP should be extended or changed to a Recall? Will you help us or direct us to whom we can contact with this safety issue? I have the Toyota diagnostic report from Toyota and Toyota Corporate Letter on email.

My 2010 Toyota Prius hatchback suddenly had 4 or 5 warning lights appear on the dashboard and my brakes failed to function properly. It felt like the power brakes was turned off ! Although I did get the vehicle stopped, it surely was a dangerous situation. I understand that Toyota knows about this problem, and have read that it was warranted if this happened before 150,000 miles. My Prius has approx 167,000 miles right now and to replace the Brake Actuator, the cost will be $ 3 - 5 thousand dollars…absurd amount in my opinion. Since this critical feature (brakes) has a long known history of being faulty on Toyota vehicles it should be warranted for at least 25 years and at least 300k ! My Prius is “unsafe to drive” and is nothing more than a paperweight…I repeat, Toyota knows, and has known about this defective brake actuator problem for years and years!!! Please lean on Toyota to up the warranty of this faulty brake problem for the MANY, MANY Toyota owners who have purchased the Toyota product and and NOT screwing the public like they are doing now !

A warranty extension went out a few years back that said one might receive a "CHECK PCS SYSTEM" warning on the dash. This has happened to us, along with 7 other lights on the dash. Between the brakes being much less responsive, and all of the pre-crash warning / adaptive cruise / radar features being disabled, this could have caused an accident. The dealer checked out the car and states that the brake actuator has a leak and that it will be a costly repair - no less than $3000. This suspiciously all happened *just* outside of the warranty window (we are within the allowed number of miles but just out of time), and also suspiciously after Toyota released an upgraded version of the actuator, and *also* after a bunch of people are experiencing the same failure. Our best assessment at this time is that the brake actuators have a factory defect and that a recall should be done.

The brake accumulator has failed on my prius which then deactivates regenerative braking, traction control, abs, and stability control. The lights for traction control, ABS, and stability control and parking brake are shown on the dash. The result for the driver is that the brake pedal has the same pressure, but does nothing until about 25% of pedal travel. At this point, the mechanical brakes will engage and provide a very sudden and jerky application to the brakes. In other words, a very non-linear brake control is present and is incredibly difficult to predict. If this vehicle is operated on the motorway, the safety of the vehicle's occupants as well as others on the road is greatly reduced. Street Toyota has confirmed this issue and its effects. They want to charge $3600 to fix this issue even though the car is only worth $5k. This problem has been investigated in the past buy Toyota and the NHTSA. Toyota has applied an extended warranty for this part meaning that they will only replace it once it goes out. They also failed to notify their consumers about this matter. It is a serious issue that has put many lives at risk and has caused multiple injuries. It is a matter that should not be ignored by either the NHTSA or Toyota.

I noticed that the ratcheting parking brake pedal has stopped ratcheting correctly, and I planned to have it inspected on the next scheduled maintenance. Recently, the brake system illuminated the traction control, ALB and "BRAKE" lights simultaneously, and the braking power diminished by more than half, with no braking until the pedal was halfway down. I depressed the parking brake pedal a few times, which cleared the "BRAKE" symbol and the problem stopped and normal braking returned. This has now happened three times with the same fix. It appears that when the "BRAKE" symbol is no longer illuminated, the problem goes away. This appears to be a software problem that triggers a braking problem to engage the traction control and ABS icons when the "BRAKE" icon associated with the parking brake is illuminated. This web site has other instances reported with the same symptoms, and Toyota had a service bulletin, which has expired, which leads to a $2000-$3000 repair bill to replace a brake booster. It appears to be software related to me, not mechanical. It poses a safety risk because braking performance is severely compromised with no warning. NHTSB needs to look into this, as rear end accidents can easily happen if strong braking in heavy traffic is required to avoid a collision. I recommend that a recall be established to fix this. An alternative cause may be a misaligned micro switch in the parking brake mechanism, which has been experiencing problems. This could lead to the "BRAKE" light being illuminated, and sending a bad signal to the computer.

I was in my 2010 Toyota Prius with my two children when I suddenly lost my brakes, with luck I was able to let off my gas and coast to a stop. Now I am left with a 3,000 dollar repair. I now know what the price of my children and my life is worth to Toyota! To find that this has already been a problem with no notification is ludicrous!

The contact owns a 2010 Toyota Prius. The contact stated that while driving 50-55 MPH, the ABS, traction control, and brake warning lights illuminated. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic and the contact was informed that the brake booster assembly needed to be replaced. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 139,999.

All the lights on my dash board came on suddenly, and the brake emergency, traction control and ABS lights stayed illuminated. Upon exiting the interstate I could not come to a complete stop at the end of the exit, which was very scary. Fortunately the cars driving on the road the exit merges into did, so we avoided a terrible accident. The brakes were spongy and not operating properly after that. The next day with all the lights still on, I slowly drove (20 mph) to the local Toyota Dealer , who claimed that error code (C1391) was being displayed and according to Toyota, that means the Booster is or will be leaking. Therefore the Pump and Booster needs to be replaced (estimated at $3K). No lights or errors were given before the incident, the brakes just suddenly malfunctioned. However Toyota apparently is aware that the booster and pumps fail without warning, because I discovered with an on-line search that code had a "customer extension" warranty (by googling the code C1391), I called customer service but they refuse to help. They claimed I was mailed a letter in October 2018 (they didn't offer to supply a copy.) However, I never received a letter or any notice from Toyota or the Toyota dealer that I have repeatedly used since I bought the car in 2010 (I have had brakes replaced there when it was under 150k and no one said anything!) Now they are stating that the extension has expired as it was only good up to 150,000 miles or 10 years which ever came first. I can't understand why they have a known brake issue and not replace the part when the vehicle is already at the dealer (It's there for every oil change 3 x a year!) Brakes are an important part of a vehicle, a failure like this should have been recalled, and Toyota should have been made to replace the faulty parts!

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the contact depressed the brake pedal and noticed an abnormal humming sound. The contact stated that the failure had been intermittent since 2016. The contact stated that the failure had become persistent. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but did not assist. The failure mileage was approximately 296,842. The VIN was unavailable.

Recently, I had ABS failure in my vehicle and warning lights came up on my dash with code C1391 which indicates a problem with brake booster assembly and pump. Now I am afraid to drive it because the brakes seem that they could fail at any time and I cannot break quickly when needed. Toyota is aware there is a problem with the brake booster assembly and pump based on prior Customer Support Programs (my vehicle was not included since warning lights were not present at the time), class action lawsuits, and petitions to NHTS about this issue. I believe the problem is prevalent enough and brakes are significant for driver safety that there should be a safety recall. My vehicle has less than 150,000 miles. I called Toyota to complain about the problem as I know it is very common among Prius owners, but they have said there is nothing they can do.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS and brake warning lights remained illuminated, and the brake pedal was firm while depressed. The contact stated that the vehicle failed to immediately stop while depressing the brake pedal, causing the stopping distance to be extended. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 120,000.

While operating the vehicle at normal highway speeds, the car suddenly had the ABS, Traction Control, and Brake lights all come on. The vehicle did not operate or sound any differently at the moment all the lights came on. However, over the next week there developed a mild humming coming from somewhere in the engine bay approximately behind the dashboard. My mechanic identified the problem as the brake booster and pump assembly failing and informed me that the vehicle may drive normally for sometime but the brakes will fail suddenly once the brake booster and pump fully fail. Thus, making operating the vehicle extremely dangerous. I am currently waiting for a Toyota specialty mechanic to become available to replace the brake booster and pump assembly at a cost of +$3,000. Please investigate this issue, there are many people experiencing this issue with the 2010 Prius models.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at 40 MPH, the vehicle consistently made abnormal sounds and jerked forward while the brake pedal was being depressed. The vehicle became inoperable. Several unknown warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the failure was due to a crack and leak in the brake booster. The vehicle had not been repaired. The contact referenced the NHTSA Campaign Number: 13V235000 (Service Brakes). The manufacturer was made aware of the failure and determined that the vehicle was no longer under warranty. The failure mileage was approximately 65,000. The contact stated this is a known manufacturing fail for the brake booster 2010 Prius.

My brakes behave strangely cause i experience inconsistent brake feel after actuation during slow and steady application after brakes on rough or slick surfaces.also, All three lights ABS light,brake light and VSC come on and off on dashboard at the same time.

A couple weeks ago we were driving our 2010 Toyota Prius and 3 brake lights came on: BRAKE, ABS, and a car with squiggly lines behind it. We took the car into the Toyota dealership ($209) to perform a diagnostic. Their results are as follows and I quote: "Hydraulic Brake Booster Pump DTC C1391 Abnormal leak in accumulator. Has T-SB and CSP that are both expired. Recommend perform repair outlined. Recommend R&R Brake Actuator Assy, Booster Pump Assy and perform ABS ECU Reflash. We wouldn't have purchased this car had we known a few years later we'd be facing a $4400 charge Toyota wants to charge. We don't have the funds let alone go now and purchase another car.

Slip indicator symbol, Brake word, Brake symbol, and ABS word lit up while driving. Brake pedal had to be pushed further down to stop the car. No warning lights or issues before this incident. Toyota diagnosed as abnormal leak in accumulator and internal brake fluid leak, and quoted replacement of the brake booster assembly with master cylinder and the brake booster pump. There is no advance indication and the brake booster will not be available while driving. Toyota recalled selected vehicles. There are currently many reports online from vehicles excluded from the recall that are affected by the same brake booster malfunction and warning lights.

The brake booster assembly and brake booster pump have failed due to a vaccine leak internally in the brake booster. Failure of the brake booster can cause the vehicle to be more difficult to stop. Yes the failure codes have been reproduced. The vehicle falls “out of warranty” for a part that should last the life of the vehicle. Replacement of the part is quoted over 4,000 dollars. The abs light, brake light, and traction control lights.

Hi I want submit issues with the master cylinder and abs pump assy I have 2 vehicles same model with average same mileage and both had issues with this system if I drove any distance below 25 mph in a constant time the dash lights comes on traction control, abs light, brake light , and the brake pedal goes low and barely brakes make this situation dangerous when I stop if you try turn it off the engine and on again lights stay there but if I reset the codes the pump works again for some while and then again when you don’t expected lose pressure and I am really afraid for my safety and my family, and I am not the only one with this problem is too many Prius owners who have the issues I went from dealer and they advice $3000 dlls fix situation who motivate people to lose money for $1200 in parts and $1800 dlls in labor for something they can resolve it because in reality is an manufactured defect

The breaking lights, skid lights and another light associated with breaks came out and I lost the ABS abilities, the hv battery is not charging while breaking. These lights comes out randomly. Very risky especially while breaking.

Due to insufficient corrosion protection, the rear brake line of my 2010 Prius burst as I pressed the brake pedal in my driveway. It dumped ALL of the brake fluid onto the ground within a couple of minutes. Imagine if I had been driving!! There could have been a serious crash!! This was sudden. There were no brakes! Pedal lost all pressure and went to the floor when pressed. Lots of warning lights and alarms screaming inside car. The vehicle has been inspected and repaired at the Toyota dealer as of 10/03/2023. I have pictures of the failed part when it was installed on the car. If the dealer is contacted quickly, they might still have the actual failed brake line (which I was charged disposal fees for.) This was very scary and numerous lives could be at risk due to the popularity of this car and its use in rideshare/taxi service. There were no warnings prior to this. Brakes worked normally. Car is well maintained with dealer service records. There is no excuse for not properly trading such a critical part for corrosion, just to save money. Peoples lives are at stake!! It's the BRAKES of the car!! Someone needs to investigate this! I have pictures and receipts I can provide.

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 did find a recall # 13V235000 (which needs to be extended). The dealership said it would cost $3,000 to replace the Brake Booster Pump Assembly and Master Cylinder. This type of repair should be recalled, and NHTSA should get this resolved with Toyota ASAP.

Affected by the recall number 10V036000, the 2010 toyota prius is manufactured with a defective brake booster and master cylinder system which causes defect of the brake system, and causes my vehicle to often lose power in abs and randomly lose abs power braking, making brakes hard, and makes for longer stopping distance. This is a problem for many and obvious reasons on the road regarding safety. All vehicles should have optimal braking systems for the road, and should otherwise be repaired at no cost if the car is manufactured with defect. This has caused no accident for me yet but the abs has failed on many occasions. I have read at least 100 cases of this given vehicle under this recall being caused an accident with faulty brakes, and sometimes complete failure to stop which is extremely worrying. This recall excludes vin numbers past a certain date, yet the recall in question is certainly still affecting many cars, as capistrano toyota has also called for petition of toyota to repair at no cost for all affected vehicles. Yet all dealerships have denied my request and toyota has no formal coverage regarding the rest of the faulty vehicles they manufactured.

Known problem for Prius with limited manufacturer liability. My breaks started failing, I am being quoted at $4000 in repairs and labor. My car is 3 years older than the recall parameters but within mileage. Manufacturer won’t cover anymore since it’s past due

Brake system failure. ABS light / Brake Light / Traction Control light. There is a recall but expired. Code C1391 need to replace Brake Booster and Brake pump. Recall should have included my car. 1,500.00 plus parts only. recall should be extended.

Hello on my 2010 Prius the ABS, Brake, Traction Control lights are all on lit up on my dashboard. Brakes are making loud noise when I stop the vehicle. I took the car into my local dealership service department. I’m being told that the brake booster and master cylinder needs to be repaired. This was a part that was put under an extended warranty with Toyota but now it’s no longer being covered by the warranty. So they want me to pay out of pocket to fix. I would like to report that they should honor the warranty agreement for my vehicle.

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.

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.

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.

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!

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!

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.

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

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.

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.

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.

Mileage: 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.

The braking system malfunction and it's available for inspection upon request. I was almost get into accident when I was driving around 65mph on I-495 because of the fail brake issue Upon online research, it turns out this is a common safety problem on the 2010 prius and toyota only issue extended warranty but not recall. the ABS light, slip Indicator light and brake system light all come on at the same time before I experienced the brake system failed

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.

Driving when I had to stop because of traffic light. Almost ran into a car because my brakes did not function correctly. ABS light and brake lights in dashboard came on. Pulled over. Called Tow truck. Had it towed to dealer. Brake Booster and master cylinder were replaced.

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.

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.

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.

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.

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.

The contact owns a 2010 Toyota Prius. The contact stated while driving 40 MPH, the ABS and traction control warning lights illuminated along with several unknown warning lights. The contact also stated that the brake pedal would depress to the floorboard while in operation. The contact took the vehicle to an independent mechanic who diagnosed the vehicle with a defective brake booster pump and ABS control module. The manufacturer was notified of the failure and informed the contact that there were no recalls or warranties on the VIN. The dealer was also notified and confirmed that the vehicle was not included in NHTSA Campaign Number: 10V039000 (Service Brakes, Air) which he linked to the failure. The vehicle was not repaired. The failure mileage was 130,000.

Mileage: 130,000

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.

Hello there, my name is Lashyrah and I do not know much about cars so most of this is unknown. The person I bought my vehicle from did not give me much information and I was desperate at the time so I bought it. Most of the lights on the dashboard are on: ABS, Brake system, Engine, Tire/Safety Alert, Fuel pump reset warning, and Stability control are lights that come and go. I have used the code system to try to reset these things and they go away then pop back up. Sometimes while I am driving, all the dashboard lights disappear and the breaks start getting really touchy and it feels completely different driving until the previous lights all come back on. This has been an issue before and when I last went to Toyota to get my car serviced, I asked them to check the lights and system, and if they could do a multi-point inspection. They wanted me to pay $300 just to find out why the lights keep coming back on. Please help me get this fixed at no cost I am a single mom and college student working part time so I need my car to get around or a free loaner car to get around until this is fixed. I strongly feel these are recalls that did not get taken care of or are not showing up in the recall system. I need assistance as soon as possible and would like to know my options, especially after getting a notice in the mail a few days ago from Toyota about my car possibly being affected. My fuel gauge is also empty at around 3 bars or sometimes 2 bars instead of going all the way down to empty, costing me more money on gas having to fill it up more often. Thank you for your time and help.

About 3 weeks ago, I was driving down PCH around Manhattan beach , California. Suddenly the dashboard lit up like a Christmas tree , the ABS light , Brake light , pre-collision system light and a yellow triangle with an exclamation point in the middle all turned on at the same time , and a loud beeping alarm went off inside the car that was deafening and most importantly the brake pedal turned very hard I had to stand up on it just to slow down to brake and my braking distance tripled . I almost hit the car in front of me . I had this terrible feeling that the car isn’t safe to drive . It feels like the brakes failed. Luckily there was an autozone nearby so I pulled in their parking lot and borrowed a code scanner . C1252 , C1253, C1319 was the codes that showed up all indicating that the abs system failed and the results is recommending to replace the brake booster pump and the abs module. There’s also a leak of some kind within the abs system. I brought it to an independent auto shop near my residence and the shop told me that the and power brake booster and the abs module needs to be replaced . The repair will cost $2.000 to get fixed in which I can not afford. I was able to seek help from my siblings and was able to come up with $1200 . So I’d figured the shop owner might be able to let me pay half first and half in 2 weeks or so when the car is fixed. But when they replaced the 2 parts with brand new ones ..yhe ECU isn’t communicating with the ABS module . The shop suggested that we bring the car to a Toyota dealership to get it diagnosed to figure out why the abs system is still faulty even when the abs power brake booster and abs module were replaced with new ones . Toyota dealership said they will charge $795 just to diagnose it . I almost passed out in shock.. I haven’t worked since the brakes failed on my car and I can’t afford to pay for the repair . Please help.

while driving on 01/31/2022, I noticed several warning lights came on suddenly on the dash and heard intermittent beefing noise while driving. I took my car to the dealership and they found M R&R brake booster and booster pump needs to be replaced and they informed me that recall warranty time of that equipment has expired and I paid for it to be replaced costing me $3539.76. Toyota motor company told me that they are not responsible to repair or replace it.

ABS and traction lights on ABS system not working was informed it is the break booster and ABS pump same as recall that ended in 2021 , I was never informed of recall and have found many other owners were not informed. At the cost of cars today many can’t afford to buy new and this is a serious Safty issue Toyota should take responsibility for the repairs

I have been experiencing issues with my brakes for last few years. I had received a letter from Toyota in 2019 stating that my car has faulty brake system and Toyota will repair the issue by replacing faulty brake components free of charge. However local Toyota dealer refused to complete the repair multiple times. First they suggested that they have not received any letter from Toyota. Then they said that they were busy and I should come back later. They also told me to put the car on Park gear or re-start the car to get rid of ABS lights. Also they stated that repair can be done anytime later until my car reach to 150,000 miles. Last week I went back to Toyota dealer again. This time they told me I should have repaired the car through extended warranty. I was also told that their former service staff must have misguided me. I contacted Toyota Customer Care and complained about this issue. They confirmed that they can see in their system that I had visited the dealer for brake issue back in 2019 and repair was not done. However they suggested that Toyota will not provide any help now. Because issue is between me and the dealer.

While driving, without stepping on the brakes, a number of warning lights came on; including brakes, ABS warning, and stability control. When attempting to stop the car the brake pedal went down a long way before the brakes engaged. I then limped home. After deciding what to do I called a Toyota dealer, made an appointment, then limped to a dealership for evaluation and service. While on the way to the dealership, the brakes were erratic; sometimes the brakes and pedal acted normally and other times it would go down a long way before braking. The warning lights stayed on.

2010 Toyota Prius. Driven about 10000 miles a year. Brake booster system went out at about the 125,000 mile mark. Reason to complain is no parts are available for repair and it is a common problem. Check out youtube.com about it. Dealer has a long waiting list, with no idea of availability. Local repair shops do not have any pumps, meaning there are many cars being driven with defective brake systems. An unusual Toyota recall for the brake problem happened in 2019 that expired in 2020 but my brakes were OK at that time. With so many Prius vehicles on the road, this problem needs more exam and Toyota forced to provide quicker relief, even a recall.

The braking system malfunctioned resulting in loss of braking ability and response along with various warning lights including ABS, Brake, and Traction Control. The vehicle produced a C1391 Diagnostic Trouble Code (DTC) indicating "abnormal leak of accumulator pressure." After taking the vehicle to a local Toyota dealer, I discovered there was a voluntary customer support program to replace what was known to be defective brake booster parts that expired in 2020. I previously did not receive any notification about the issue and am now told it will cost thousands of dollars to replace the brake booster parts known to be defective. I now have a vehicle that is unsafe to drive unless I spend an exorbitant amount of money to replace the aforementioned parts.

The ABS, Brake, and traction control light came on. The braking became difficult. The car did stop but if it was in an emergency circumstance there may have been a collision. I called Toyota about the issue and was informed that there was a brake actuater and master cylinder issues with this make and model. Toyota replaced them in cars that had this issue under a special warranty that was over in 2021. It is a $3500 issue. I purchased this car new and have never received a notice about bad braking system. I have lived at the same address since the purchase. Toyota informed me that notices were not sent out, however if the owner came in with this issue before 2021 it would have been repaired and replaced. I can not understand how ALL owners were not informed. I do not understand how a recall wasn't enforced. I live in Florida where the speed limit is 70mph. This could have been deadly. I looked on forums online and apparently this has been an issue for many many 2010 Toyota Prius. I have a case in with Toyota American. 220701001489. I can use any help I can get with this issue. It may save a life.

The brakes ABS stopped working. It is a known issue and is effecting many older Prius drivers.

The contact owns a 2010 Toyota Prius. The contact stated while driver was driving 65 MPH and depressing the brake pedal, multiple times, the vehicle brakes failed to stop the vehicle within a reasonable time. The contact stated there were several unknown warning lights illuminated simultaneously. The driver was able to slow the vehicle using the parking brake and driving onto the grass on the side of the road. The driver was able to continue driving to the local dealer. The vehicle was diagnosed and the contact was informed that the braking system needed to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was 179,747.

Mileage: 179,747

Brake booster failed. Brake Actuator failed. ABS,BRAKE and TRACTION control light is on.

I purchased my car in January 2010 within that first year I noticed that randomly if I hit a bump in the road and I would apply my brakes my car would do a wired skid and I couldn’t break properly. This has continued the entire time I’ve owned my car. Last month I was driving down the highway and ABS! Red brake light and ABS warning light all illuminated. As I was exiting the highway and applying the break I noticed my brakes were very spongy taking considerably more effort to stop. I started noticing a few months ago my breaks took considerably more effort stop and breaks felt spongier. The day my warning lights lit up a mechanic stated a code of C1391 was detected. Indicating break booster problems. NHTSA issued a recall Rep 13v235000 which is Break Booster my car was manufactured 10/09 so I understood my car was part of this recall but Toyota claims that is not a recall but a customer support program which has expired 2 years ago. I’m the original owner w/ 69,000 miles. Clearly my vehicle has and continues to have break issues so why is Toyota shirking responsibility and endangering me and other drivers allowing a car w/ breaking issues to not be properly repaired under the recall

Brake booster/ Brake Actuator problems

I believe Brake Actuator seems to be malfunctioning. Noises come from the location of the Brake Actuator when I am lightly braking at low speeds. I am getting Antilock Braking System code "C1256" reading "ACCumulator Low Pressure". There are a similar recalls related to my issue. Recall number: 10V039000 and Recall number: 13V235000

A known defect was briefly recalled, then sunsetted. My brake attenuator has failed, as has been the case for many others on this model. Toyota has acknowledged the defect, but no longer supports it.

Normal braking pressure failed to stop the vehicle requiring the driver to apply very heavy pressure to stop the vehicle and avoid a rear end collision. Multiple dash lights appeared and the vehicle was towed to a Toyota dealer. The dealer confirmed codes C1252 and C1256 exist and recommended that the brake booster pump assembly be replaced. An August 6, 2018 Toyota Service Bulletin (T-SB-0079-18) recognized this problem. Toyota sent Customer Support Program Notification ZJB noting that "Toyota has received reports about certain internal malfunctions of brake booster assemblies in some of the subject vehicles. In these reports, customers have noted various brake system related warning lamps illuminated." Toyota noted that, "This is not a recall." Toyota suggests that certain warning lights may illuminate but does not warn drivers that normal braking may cease and that the vehicle can be dangerously difficult to stop.

ABS brake light on. Just purchased this vehicle and found Toyota knows of a defect in the master brake cylinder that causes it to leak. Toyota was repairing this problem free of charge till 2019. This vehicle has never had the repair. I am told brakes may go from power brakes to non power brakes while driving. We are not driving till it gets fixed because of safety problem with brakes.

There is a known problem with 2010-2015 Toyota Prius brake actuator assembly and also the brake booster pump assembly. A leak develops and cannot hold proper brake pressure which will lead to catastrophic failure of the system and a life or death brake failure. Toyota has acknowledged the problem and issued a recall only covering 150,000 miles or 10 years from date of first use. This recall should be extended to all affected vehicles for the LIFETIME of the vehicle given that it is a known manufacturing defect affecting life and limb and that repair costs average over $3000.

Brake booster/ brake pump / accumulator sudden failure BELIEVED TO BE CAUSED BY THE SENSOR WARNING SYSTEM ⚠️ THAT ABS LIGHT ASSOOCIATED WITH CONSTANT BEEPING NOISE, 10 SECONDS LATER LOSE OF BRAKE POWER. factory trick to get brake service, at large for this repair costs 3800 per dealership toyota carlsbads. Manipulative recall 🤔 disallowed me on 3 occasions unable to get part replaced by Toyota. When contacting corporate the did not demand me to get fixed and not drive NY car, again getting my car to tge service station experienced noise occurring then sudden outage of brake power reduced to nothing. A similar youtube video and my personal video explain sudden loss of brake power or pressure... after lights go on. And immediately return to normal after lights get reset. Sensor failure leading to brake failure, really scary and obviously a big problem TOYOT SHOULD STILL BE RESPONSIBLE FOR. CONSUMER SERVICE PROGRAM BY TOYOTA FOR THIS BRALE BOOSTER ISSUE STOPPED FOR SOME REASON IN 2019 ALSO. 150K BS RULE. MERCEDES BENZ HAS TAKEN THE RIGHT ACTION TO FIXING BRAKE BOOSTER ISSUES.

Hi- I have a Toyota Prius 2010 model and I encountered a braking failure yesterday. My ABS lights, brake lights and another light came up on my dashboard of the car. Upon diagnosis, I was informed by Toyota dealership that my car has a faulty C1391 - Abnormal leak in accumulator. This condition may be caused by small internal brake fluid leak inside the brake booster assembly with master cylinder. This is a known issue by Toyota and lots of press coverage on this issue since the past few years. I was told today that if this issue occurred within 10 year or purchase or <150K then the repair work would be covered by Toyota. I purchased the car in 2010 and I past the 10 year mark but mileage coverage is 125K (<150K). Toyota is unwilling to bear the cost and would want me to pay for the fix. This is a known issue with Toyota and the braking system can fail anytime before/or after 10 year mark. It is now costing me $3000 to repair. I am shocked with the Toyota's response in this matter. There are lots of blogs I read online who have similar issue. Class Action lawsuit: https://www.classaction.org/news/toyota-hit-with-class-action-over-alleged-refusal-to-fix-braking-system-defect-in-hybrid-vehicles Here is one example: https://www.youtube.com/watch?v=xA9jyrbZDWo Thanks.

The Traction control, ABS, and Brake light all came on simultaneously. It was random with no trigger. The brakes feel spongy, and will not regenerate to charge the hybrid system.

My brakes have been making hissing noises whenever I press on the brake pedal for the past year. While driving on the freeway 300 miles from my home, numerous lights on my dashboard came on including brake, VSC, PCS, ABS, Triangle and "CHECK PCS SYSTEM" warning message. The brake also makes pumping noise every 4 seconds. The vehicle has no regenerative braking. The brake pedal is mushy and doesn't slow the car down until the pedal is fully depressed. I contacted Toyota and was told that there was a Customer Support Program ZJB that covers 2010-2015 Prius Vehicles for Brake Booster and Brake Booster Pump Assemblies. However, that program only covers 10 yrs 150 miles. My Prius has 110k miles but it's 21 months passed the program coverage. The car is dangerous to drive and Toyota will not honor the recall. I am stuck with a car with no brakes.

On March 25, 2022, I was driving my 2010 Toyota Prius, approx. 209,000 miles. When I had parked my vehicle, and turned my A/C on, my vehicle started to make this annoying beeping noise non-stop and all of the light on the dashboard had lit up. My brake lights, ABS, and the slip indicator all came on. When I went to drive my vehicle all of sudden my brakes did not respond. I had to force break and push down on the brakes very hard, to the point where I'm flooring the brakes. I checked with Toyota to see if there was a recall on my vehicle, and they told me that there were no recalls. When I did my research on 2010 Toyota Prius, I found that this is a common issue that the brake actuator and brake booster pumps are faulty on these vehicles. I did not receive a recall notice for this vehicle. Currently, my vehicle is not drivable and not safe to drive. For this to happen out of nowhere with no warning is unacceptable.

As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.

A number of things have failed on this car. 1. The hybrid battery pack system shut down and warned that I needed to see a mechanic. My mechanic diagnosed that the hybrid invert was defective and causing the battery pack to fail. 2. When braking at both low and high speeds, the car increasingly struggles to come to a stop. When applying foot pressure, you can hear the pump winding - this occurs while at rest as well as when trying to slow the car down. There are times when applying the brake that the floor pedal will lock and cause the car to skid while barely reducing the speed of the car. I have had multiple near accident incidences as a result and put myself and others at risk. 3. The car ferociously vibrates every morning - discovered that the head gasket has failed prematurely and due to the car overcompensating for the failing hybrid battery that is being impacted by the failing hybrid inverter. All problems have been reproduced and diagnosed at independent service centers. Multiple codes, warning lights and messages have alerted me to engine and battery issues - all of which appeared after the various issues and failures.

2010 Prius Brake, ABS, Traction Control Lights On/Off with no codes I bought new car and running smooth so far. I got this lights 2 months back and off for sometime and came back on and off and now quite often coming back and forth, 106K miles had the ABS, Traction Control and Brake light all come on at once same time and off same time and back and forth. No codes and no flashing but this is very critical as all related to brake systems failures may leads to crash because we don't know when this lights on and off and no codes to fix this issue.

For the past 2 weeks my prius has been acting very strange. When driving I have a hard time coming to a stop when pushing the brake and I realize that that the ABS light is on as well the brake light is on. Sometimes it will work fine with the lights off, and somtimes it messes up again. I heard that it could be a brake booster or module. I believe it was already recalled a few years ago, but seeing a lot more people complain about recently is a bit concerning. The part that was replaced, it should work for many years not less than 10. Its a huge risk for myself and others. I didn't realize what was happening until I needed to stop fast. This needs to be fixed fast and the right way this time before somebody dies

Brake system fails under normal driving conditions. Dealership diagnostics confirmed this falls under the Customer Support Program ZJB. This program expired in 2020 and Toyota customer care is unwilling to fix or reimburse for the $2200 expense associated with the defective brake booster and brake booster pump assembly. The Toyota case number is #220318001387.

In Nov 2020 I was informed that my ABS actuator needed to be replaced since all warning systems went off and brakes were disabled. On March 13, 2022 the ABS and traction system warning came on again . On March 14, 2022 I had my car towed to Daves Ultimate Automotive in Austin, Texas because my brakes failed. They told me I needed to replace the Brake Booster which is going to coat me $2500. I have looked at car complaints and this seems to be a faulty system that Toyota is aware of because they extended a warranty to Dec 2019. It is my belief that this should be a recall because of the dangerous potential of no brakes when this system fails.

Brake warning lights, traction control, and ABS warning lights all illuminated on the dash. Taken to the dealership and was told brake failure due to actuator or brake boost. Upon further research, it looks like this is a known issue with the Prius but Toyota is only providing service/repair to certain vehicles who already show brake failure instead of issuing a recall for all potentially affected vehicles.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the vehicle started making a beeping noise. The contact stated that an unknown warning light was illuminated. The contact pulled into an apartment complex and while depressing the brake pedal the failed to respond. After driving over several speed bumps and using extra energy to depress the brake pedal the vehicle responded and slowed to a stop. The vehicle was towed to the dealer where it remained. The contact stated the dealer informed her that the brake master cylinder and brake booster pump needed to be replaced. After researching the cause of the failure, the contact referenced NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer was contacted and informed of the failure. The contact was then informed that the vehicle warranty had expired. The approximate failure mileage was 180,000.

Mileage: 180,000

The contact owns a 2010 Toyota Prius. The contact stated while exiting the highway and getting into the right lane at 60 MPH, the ABS warning light, brake light, and the traction control warning light illuminated and the vehicle lost braking functionality. The contact depressed the brake pedal with added force to get the vehicle to slow enough that he was able to get off of the highway ramp and pull over. The contact turned off and restarted the vehicle; however, the warning lights were still illuminated. The contact stated that extra force was needed to stop the vehicle. The contact drove the vehicle to his residence. The contact has not taken the vehicle to a local dealer. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 182,000.

The Brake booster and master cylinder failed causing the braking system to fail while driving

My prius appears to have the same problem that an excessive number of other 2010 priuses have with it's regenerative braking. This is a common and well known issue among these cars. Despite the fact that I am at 132k miles, under the 150k limit for the extended warranty, I am going to be stuck spending thousands and thousands of dollars to get my vehicle fixed because it is about 2 years past the 10 year limit.

While driving, my traction lights, ABS light, and Brake light came on the dash with no noises or other messages. I noticed my brakes took significantly more distance to stop and then stopped working altogether. I had to use my emergency brake to get stopped safely.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS, traction control, and parking brake warning lights illuminated. Additionally, the brake pedal was difficult to depress. The vehicle was taken to the dealer and diagnosed with brake booster pump assembly failure. The brake booster pump assembly needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included in the recall. The failure mileage was approximately 88,500.

Mileage: 88,500

The brake assembly is noisy while stopped at lights. The brake pedal continues slowly downward when pressed as if there is a leak in the brake master cylinder. Toyota has issued a warranty extension for a problem of fluid leaking in the brake booster, but did not notify me. Toyota's code for the warranty extension is Customer Support Program ZJB. Two local dealerships have refused to perform the repair because the warranty extension expired before I became aware of the issue.

2010 toyota prius brake booster failure. according to multiple resources online, there have been known issues with this part from Toyota across multiple models. After recalling only a small portion of vehicles due to this failure, complaints have been filed with nhtsa to address toyota's lack of corrective action regarding the vast amount of vehicles utilizing this technology. this is a dangerous defect that caused my brakes to malfunction during a cross-country trip. my brake and ABS lights suddenly came on, and i could tell my prius handled differently. the brake pedal became hard to depress and stop time increased drastically. i am having a mechanic diagnose and repair this issue costing no less than $1200 in austin, TX. i would like to make a complaint to toyota for not recalling all the models with this issue and instead choosing to recall a minute fraction of potentially defective vehicles.

Brake Booster Failure; has been inspected and confirmed. Warning lamps for traction control, ABS, Brake System Lights, Master Warning Light all came on during normal city driving. Immediate loss of Brake Assist causing sudden need for much more distance while stopping the vehicle. Clearly, sudden changes in brake behavior is a safety concern and this problem seems to be well documented as common issue in this era of Toyota vehicles. I believe Toyota has fallen short in its efforts to remmedy the situation. An extended warranty was issued but it was for a brief period of time that required this problem to occur within a narrow window. It's a wildly expensive repair to a critical system and it seems to be a common problem in these cars.

We have a 2010 Prius Purchased March 2010. Toyota issued a "Customer Support Program" (free extended warranty) for the brake booster and brakebooster pump assemblies in 2019. The Primary Coverage was offered until 11-30-19 regardless of milage. After that the secondary coverage applied for 10 years or up to 150,000 miles. The information mailed to us states; "If you have not experienced the condition described above, there is no action necessary at this time." We did not experience any brake problems until 11-10-21, when the dash display lit up with the BRAKE LITE, ABS LITE, SLIP INDICATOR LITE, AND THE ! LITE, ALL CAME ON AT THE SAME TIME. ALSO THE BRAKE PEDDLE BECAME SPONGY AND AT TIMES VERY HARD TO DEPRESS. We had our Toyota dealer run a diagnostic scan of the vehicle and they determined the brake booster and brakebooster pump were defected. The car has 70,000 miles on it at this time, and we have owned the car for 10 years and 8 months. Toyota will not honor this Customer Support Program since we are 8 months beyond the expiration date. There was a RECALL number 13V235000 issued 06-05-13 for the same exact problem, with NO EXPIRATION DATE. However, Toyota says it does not apply to our car. This problem causes the power brakes to not work as power, only manual brakes (Hard to Push). They also become very soft and not responsive if the engine has not run since the last time the brakes were pushed. THIS IS A DANGEROUS SAFETY ISSUE! ! ! My question is, the problem was a big enough to have Toyota issue this 10 year "Customer Support Program" to prevent a hazardous situation from being on the road for 10 years, why is it not hazardous NOW 8 months later? We welcome any help you can provide.

I have a 2010 Toyota Prius. The ABS pump unit broke down while driving on the road. Suddenly the breaks were not functioning correctly. Breaks got squeeze. Apparently it's a common issue and Toyota had a program around it to fix it till Jan 2021. But I couldn't go fix it before coz the lights didn't show up. Now in Oct 2021 it's broken and is not covered. I don't know how a company gets to call such a safety issue as option and not a recall and get away with it. The vehicle has already been identified as having a bad part. How come the company does own up to it considering it's an important part of the breaking system.

while driving traction, abs and brake light came on. braking feels forced by driver.

The brakes, ABS, and traction light came on car but it does not stay on. Took it to the dealership and the advisor said it would be $2,500. If this gas been a recall in the past then it should still be a recall. I am extremely disappointed in Toyota as a whole to bail out on something that is as crucial as the safety of brake failure.

The Brake Booster assembly for nearly all 2010 Toyota Prius has innate failure over time. It is a faulty, known-issue part. Toyota offered some limited-time warranty extension fixes instead of a full recall. My Toyota dealership informed my that my part needs the fix, as would be expected, but that I am not within the limited warranty. As this is a safety issue and the part has given out, I am stuck. I contacted Toyota directly and via email as well and they refused to do anything while acknowledging the part was their fault. They were very snooty about the fact that a full recall had not happened yet, and gleeful to deny me service.

I have recently bought a 2010 Prius. The ABS (!) , traction control, and emergency brake light all illuminated three days after I transferred title with the dmv. This apparently is a very common problem with this car. I am told that these lights lead to a very expensive repair. My primary concern is my safety and of course the safety of others. A car that has brakes that suddenly fail is lethal. I was advised by a helpful agent that these repairs would come out of my pocket. My complaint is that Toyota should be responsible for this. I cannot drive this vehicle at the moment because I refuse to endanger anyone.

Hazards lights came on and would not go off, with increased speed hazards flashed faster. Toyota stated that ABS actuator and relay needed to be replaced.

Parked with car running. Car started beeping (beep beep beep) incessantly. Turned off. When I turned 2010 Prius back on, the beeping came back. Brakes DID NOT WORK. Dash error said "CHECK PCS SYSTEM" and many warning lights were on. Pressing brakes didn't stop vehicle.

As many other 2010 Prius drivers have experienced, my brake actuator has failed. This has resulted in loss of braking and potential harm.

code C1391 master cylinder internal leak

ABS pump failed, all the lights came on the dash for brake, and brakes stop working properly it still drives but unsafe to do so, Toyota says it’s common problem and they want $3000 to replace it

ABS brake booster slow leak. There are many reporting the same problem on YouTube as a $3000 repair.

Brake assist has failed. Appears to be master cylinder assembly and/or pump? Brake related error lights and safety systems disabled. Very difficult to drive vehicle without power brakes. Car only has 106k miles on it, and too old for enhanced warranty coverage (acknowledged problem). This is not some 20 year old car with 300k miles on it.

First problem the light on my dashboard appeared. My braking is starting to not work properly. When i press the pedal it feels soft, and the brakes are not bitting well. Next thing my abs is not working, that i skid multiple times, and that cause me a few times to almost get into an accident. I had few fender bender issues, but no major damage collision. I end up paying for the repairs of my car, and have the receipt to prove it. Also before having all these issues, with the regenerative braking itself, if i happen to hit a pothole, even thou i’m pressing the brake pedals. It causes the car to accelerate. This only happens during traffic stops that i’m already pressing the brakes, but for some reason if i hit a pothole, like i mentioned above. That car accelerates, and thus cause me to almost hit the car in front of me. I was aware of this issue, so to compensate, i pressed the brake pedals harder whenever this incidents happen.

My 2010 Prius is experiencing brake booster failure. Brake assist appears to be lost. Feels unsafe to drive since braking distance feels longer. Unsure if stability control is working. Hybrid battery not recharging from braking. Warning lamps include: 1) Brake System Warning Light (red indicator); 2) Brake System Warning Light (yellow indicator); 3) ABS Warning Light; and 4) Electronic Stability Control Active Warning Light. OBD-II trouble code: C1391 (abnormal leak in accumulator). Spoke with representative Tracy at Toyota Customer Experience Center (888-270-9371) on 7/30/2021 (Case #210730000924) and Randall at Toyota Customer Experience Center on 8/3/2021 about repair through Toyota. Both representatives acknowledged that Toyota was aware of the brake booster failure from owners. Randall acknowledged that many owners have complained to Toyota about brake booster failure and that is it commonly reported to Toyota, hence Toyota issued a Toyota Customer Support Program Notification ZJB. However, I am told that coverage for my Prius under Notification ZJB has expired, that there is not a recall for the defective parts, and that Toyota will not assist with fixing this problem for my car. I believe this problem is a safety issue and that Toyota needs to issue a recall as soon as possible to remedy this known defect.

MULTIPLE WARNING LIGHTS CAME ON SUDDENLY WHEN I WAS DRIVING THE PRIUS LAST MONTH; 'ABS', 'BRAKE', AND 'TRACTION CONTROL' WARNING LIGHTS ALL CAME ON SIMULTANEOUSLY. THE BRAKING FUNCTION WAS NOT NORMAL. HAD TO DEPRESS THE BRAKE PEDAL A LOT MORE FOR THE BRAKE TO BE APPLIED. ALSO BATTERY IS NO LONGER RECHARGING ON APPLYING BRAKES. TOOK IT TO THE LOCAL TOYOTA DEALER (FRED ANDERSON, RALEIGH, NC). THE ESTIMATE FOR REPAIR IS $4045. THE CAR IS 2010 MODEL (11 YRS) AND HAS 106000 MILES. THIS IS KNOWN PROBLEM AND IN MY OPINION AND DESIGN FLAW AND TOYOTA NEEDS TO FIX THIS. PLEASE HELP.

All my lights are on traction, brake, ABS!

Brake light, ABS light, and traction control light all illuminated on dashboard. Took the vehicle to Toyota dealership and they determined I needed to replace the brake booster/accumulator and pump assembly, cost was $3,000.00. Looking into this issue further it is an extremely common issue and should be a recall item.

After buying the car from Liquidation Station (used car dealer) the day after we bought the (2010 Prius Hybrid) the breaks went completely out. My daughter and grandchild were in the car and she almost crashed in to on coming traffic putting them in extreme danger of being killed. We had the car towed to Caldwell Toyota in Conway AR. and they said the break booster had failed and that they would not cover the cost of the repairs even though there are several complaints of break failure and several recalls for this car.

While driving on a highway at night around 60 mph, brake light turned on then AB light then slip light. Nothing else happened but since this hadn’t happened before, I pulled over, turned off car, waited a bit then turned back on. Car still worked although these lights stayed on. Continued driving to get home at reduced speed (around 45-50) plus with blinkers on with mental note to take to the dealer next morning. A few miles out, a loud unchanging alarm went off and I couldn’t use my brakes no matter how hard I pressed on them. I was able to glide off an exit that was near and making right turns get into a lot. Also neither of the brake pad nor the parking button was working so I couldn’t stop the car but then I hit power to shut down and that was able to stop it. Called for towing to dealer the following day. They say it’s the brake booster and that I have to pay out of pocket since it passed a recall but this is a dangerous issue with the car. If the light had been red and a car crossing, without brakes I would have gotten into an accident and since I bought it used last year, I wouldn’t have even known about this being an issue. There shouldn’t be a date limit on this recall, if models of Toyota Prius needs the recall and it hadn’t been done by previous owner, it needs to be done as this is a really traumatizing and potentially deadly issue.

I was driving when the car started to beep constantly. I tried to turn on a road to check it out and realized I had no brakes. I passed the road I was trying to turn on and had to coast to a stop down the road. If this had happened while coming to a red light, there is no way I would have been able to avoid a wreck. I did some research and found that they extended the warranty on the brake booster and assembly pump. The thing is I had taken the car in because the abs, brakes, and traction control lights came on last year. They acted like they had no clue what was wrong and just unplugged the battery and hooked it back up to make sure the lights went off. The lights were off for less than a mile and when I called back they acted clueless and said for $200 out of pocket they can do more extensive testing but said they saw nothing wrong and that the car was driving normally. How does Toyota have a major problem that they extend the warranty and the Toyota dealership knows nothing about it and can’t give me answers when I have the exact issues the extended warranty is supposed to cover? I could have been seriously injured and hurt someone else and Toyota doesn’t care. Their representative told me that they had done enough and it was on me to fix the problem as now I was no longer covered under their extended warranty. This is a major safety issue and needs to be a recall before someone gets seriously hurt. Toyota knows there is a problem but refuses to hurt their bottom line to protect the consumers. This just happened yesterday and I have not done anything to the car at this time.

Actuator and brake cylinder have gone. ABS, traction, and brake lights all have gone on. This is a very common issue with this car, and I am expected to pay $3,000 for this fix.

The brakes failed while driving. The traction, ABS and brake light all came on, on the dashboard and the brakes were working at 10% or less. I had to use the engine braking mode to stop the car. I took it to a technician and this is a known issue that Toyota is ignoring.

ABS light and brake light comes on and goes away on my toyota prius 2010

I have a 2010 Toyota Prius. I was driving home on I-80 and when I was getting down on the slope of the Sacramento river bridge, three lights suddenly popped on the dashboard - ABS light, Brake light and Traction control light. Following this, I lost efficient control on the brakes and I had to push really hard on the brake pad to even slow the car down. If I had to stop suddenly, it would have definitely resulted in a serious crash. Because the brakes stopped working as they are supposed to, I turned on the blinkers, took the exit and tried to stop slowly. I was able to stop on the side of the road just before the red signal. I was just couple of miles from my home so I kept the blinkers on, and slowly drove through internal roads to my home. Later when I found out the code, it came as C1391 which is usually for failure of the brake booster assembly or the brake booster pump assembly or both. When I contacted my local Toyota dealership, they mentioned that the extended warranty for replacing these parts ended in November 2020 and because of that they asked me to take care of this >$3000 repair. I also contacted Toyota corporate to file a complaint and was told the same thing. This issue is a serious safety concern and Toyota should issue a recall and not an extended warranty. They should not be waiting for people to loose their lives before they issue a recall.

While driving in the highway had several times hard situations. Yesterday and truck became in front in my lane while, I had brake fast the car started loosing control and ended up on the side of the road. Is like the brakes makes the car loose all the control in a bad situation instead of help to prevent accidents. Each time I go to Toyota I had mentioned this issue, but they say there's not recalls available. Sometimes I think I will die because of this.

Code 1391. just like many others Toyotas of this year

My problem began when I pressed my brakes and instead it accelerated. I thought maybe my foot slipped and didn’t know what it meant. It happened again a few weeks later and then all of the dash lights went on that indicated that I had to have the big brake recall repair. Being that my car is past the 10 year warranty and past the extension for mileage, I had to pay out of pocket. This repair was done and upon receiving my car back, the gas mileage instantly began to drop. It went from averaging 42-48MPG in my town to 25-30MPG. I took it in the be looked at and they ensured me nothing was wrong with the car AT ALL. The battery wasn’t holding charge on top of this and it wasn’t reading the same on the dash about the 0-100 current gas mileage you’re getting as you go (the lines scale thing) that goes up when you let off the gas, and I could feel a strange shift while I was driving so I took it in again. They told me this time it’d be $110 to diagnose even though it was the same issue that started after the brake system repair, so I left extremely upset. A few days later my cars steering went out while I was driving and the whole hybrid system died. The car now only works in power mode. The consumer stated the car was taken in for a brake recall and had to pay $2800 in repairs. The consumer stated what they thought was a battery failure turned out to be the beginning of an electrical motor failure related to overheating.

Impending failure of the brake booster / brake booster pump assembly. ABS and brake warning lights remain on and a constant electrical whining sound can be heard from the brake booster assembly. Toyota is aware of the problem and offered a customer support program that expired in 2019 ( https://attachments.priuschat.com/attachment-files/2019/12/178663_162714_ZJB_Phase_2_.pdf )

I WAS DRIVING AND THREE LIGHTS CAME OUT: ABS, BRAKE AND SLIP INDICATOR.

I WAS JUST TOLD THAT MY 2010 PRIUS NEEDS THE BRAKE BOOST ASSEMBLY (CYLINDER AND BOOST) AT A COST OF $2,570. IT WAS CAUSING MY 4 MONTH OLD, 12V BATTERY TO DRAIN. I THOUGHT THAT WAS OUTRAGEOUS SO I LOOKED INTO IT AND FOUND OUT THERE WAS AN "ENHANCED EXTENDED" WARRANTY ISSUED (NOT A RECALL) , BUT FOR MY VEHICLE IT EXPIRED APRIL 2020. ANOTHER ISSUE THAT I UNCOVERED THAT THIS PART ALSO CAUSES THE PRIUS TO LURCH FORWARD WHEN BRAKING AND YOU HAPPEN TO DRIVE OVER A BUMP. TRAIN TRACKS, OR POTHOLES WHICH IS A SAFETY ISSUE. I HAVE ALSO EXPERIENCED THIS WITH MY PRIUS. FORTUNATELY, I HAVE HAD NO ACCIDENTS SO FAR. I HAVE READ THAT THERE HAVE BEEN ACCIDENTS CAUSED BY THIS ISSUE. TOYOTA SHOULD STEP UP AND FIX THE PROBLEM BEFORE PEOPLE ARE INJURED DUE TO THIS DEFECTIVE BRAKING SYSTEM. MY DAUGHTER DRIVES A 2015 PRIUS. IS ANYTHING MORE BEING DONE? OR ARE THEY GOING TO WAIT UNTIL MORE ACCIDENTS HAPPEN? I STUMBLED ACROSS THIS ISSUE WHEN MY 2010 TOYOTA PRIUS 12V BATTERY REQUIRED FREQUENT JUMP STARTS. I REPLACED THE BATTERY ($300) DEC 2020. PRIOR TO THAT, I CALLED AAA AND GOT A JUMP START. BECAUSE OF COVID, I WASN'T DRIVING THE VEHICLE DAILY (WORK FROM HOME) SO IT WAS ASSUMED THE CAUSE WAS THE VEHICLE SHOULD BE DRIVEN FREQUENTLY.

I WAS DRIVING AND PRESSED THE BRAKE PEDAL TO MAKE A TURN. AFTER COMPLETING THE TURN I NOTICED SEVERAL WARNING LIGHTS ILLUMINATED ON THE DASH BOARD INCLUDING BRAKE, ABS, AND TRACTION CONTROL. THE BRAKES WERE VERY MUSHY BUT WORKED ENOUGH TO GET THE VEHICLE TO A SHOP. THE SHOP ASSESSED THE VEHICLE WHICH DISPLAYED CODE C1391 AND SAID IT WAS BRAKE RELATED POSSIBLY ABS SYSTEM. THEY CLEARED THE CODE IN MY VEHICLE AND BRAKES WORKED NORMAL FOR A VERY SHORT TIME BEFORE THE SAME WARNING LIGHTS APPEARED AND BRAKES WENT MUSHY AND NOT WORKING PROPERLY. I THEN LOOKED UP POSSIBLE RECALLS OR ENHANCED WARRANTIES AND I CALLED TOYOTA CUSTOMER SERVICE AND WAS TOLD THERE IS NO RECALL OR EXTENDED/ENHANCED WARRANTY FOR ANY BRAKING ISSUE ON MY VEHICLE BASED ON THE VIN NUMBER. I TOOK THE VEHICLE TO MY LOCAL TOYOTA DEALER AND THEY CHARGED ME TO TEST FOR A CODE. THEY CAME UP WITH CODE C1391 AND STATE IN THEIR PAPERWORK THAT THE CAUSE IS "BRAKE BOOSTER INTERNAL FAILURE" AND RECOMMEND REPLACING THE BRAKE BOOSTER. THEIR PAPERWORK SHOWS REPLACEMENT OF A BRAKE PUMP AND BRAKE BOOSTER HAD AN EXTENDED WARRANTY BUT THAT IT EXPIRED 9/26/2020. THEREFORE THE DEALER WOULD NOT FIX MY CAR AT THE COST OF TOYOTA. MY VEHICLE HAS APPROXIMATELY 91,000 MILES AND OTHERS WITH HIGHER MILEAGE HAVE DOCUMENTED THAT TOYOTA HAS REPAIRED THIS KNOWN, WELL DOCUMENTED, EXPENSIVE (ABOUT $4,000) AND CONTINUED DANGEROUS BRAKING PROBLEM IN SEVERAL CASES. PER THE DEALERSHIP AND MY CONTACT WITH TOYOTA THEY ARE NOT WILLING TO REPAIR MY VEHICLE AT THEIR COST., WHICH AT THE TOYOTA DEALERSHIP IS ABOUT $4,000 PARTS AND LABOR. AN ADDITIONAL ISSUE IS TRUSTING TOYOTA SERVICE AND/OR PRIVATE MECHANICS THAT THEY WILL REPLACE THE PROBLEM PART(S) OR REPLACING ADDITIONAL PARTS MAKING THE REPAIR BILL HIGHER OR MAYBE NOT FIXING THE PROBLEM WHERE ADDITIONAL REPAIRS WILL BE REQUIRED BEFORE TOO LONG.

I INHERITED A 2010 TOYOTA PRIUS 3RD GENERATION WHEN MY MOTHER PASSED A FEW YEARS AGO. I'VE SINCE HAD SEVERAL UNNECESSARY AND COSTLY PROBLEMS WITH THE CAR AS WELL AS DEALERSHIP'S OUTLOOK, TREATMENT, AND INDIFFERENCE TO THE DANGER THAT THEIR CUSTOMERS FACE--AS MANY ALREADY HAVE. THE FOLLOWING ARE SITUATIONS THAT I'M EXPERIENCING NOW. FIRST, I WAS RECENTLY LEAVING THE PHARMACY WHEN ALL OF MY WARNING LIGHTS (ABS, BRAKE, TRACTION ) SUDDENLY CAME ON AND MY BRAKES FAILED AS I WAS HEADING HOME. I'M A SINGLE MOTHER OF A SPECIAL NEEDS CHILD AND I HAD TO GET HOME TO HER. I WAS APPROXIMATELY 1 MILE FROM MY HOME AND I WAS NEARLY IN 3 ACCIDENTS THAT COULD'VE BEEN CATASTROPHIC. THANKFULLY THE ROAD WAS DRY, CLEAR, AND WITH LITTLE TRAFFIC. WE HAVE BEEN HOMEBOUND FOR WEEKS, WITHOUT TRANSPORTATION FOR DOCTORS, FOOD, ETC. OUR VEHICLE IS OUR ONLY MEANS OF TRANSPORTATION, AND WE MUST GET TO DOCTOR APPOINTMENTS, ETC. SECOND, THE CAR HAS INEXPLICABLY STALLED TWICE. THIRD, I'M CONSTANTLY HAVING TO REPLACE LIGHTS, AND HAVE BEEN PULLED OVER BY THE POLICE FOR LIGHTS NOT WORKING. FINALLY, AN AIRBAG HAS BEEN RECALLED AND ONCE I CAN AFFORD IT I'LL GET THAT FIXED AS WELL. I SPOKE WITH MY LOCAL TOYOTA DEALERSHIPS, AND AFTER EXPLAINING THE PROBLEMS, I WAS INFORMED (SEVERAL TIMES AS I WAS REPEATEDLY TRANSFERRED) THAT I HAD TO PAY AN INSPECTION FEE THAT ALSO CHANGED WITH EACH PERSON. FINALLY, I WAS TOLD I HAD TO LEAVE MY CAR THERE FOR DAYS AND THAT I WAS GOING TO PAY THOUSANDS OF DOLLARS TO FIX THE CAR. I'M UNABLE TO PAY THAT MUCH MONEY--AND THE AMOUNT KEPT CHANGING AS WELL. I HAVE RESEARCHED THESE PROBLEMS AND NOW UNDERSTAND THE METHODOLOGY AND INTIMIDATION USED ON POOR PEOPLE SUCH AS MYSELF. TOYOTA SHOULD BE ASHAMED. FIX THESE PROBLEMS THAT WILL ENDANGER AND POSSIBLY KILL YOUR CUSTOMERS FOR NOTHING MORE THAN THEIR OWN INCOMPETENCE AND GREED.

TOYOTA PRIUS 2010 STARTED EXPERIENCING BRAKING ISSUES IN JANUARY 17, 2020. CAR WAS TAKEN TO THE DEALER THREE TIMES WITH MISS DIAGNOSIS. IN MARCH DEALER DIAGNOSED ISSUE MOST LIKELY A BRAKE BOOSTER AND PUMP ASSEMBLY WHICH WAS A KNOWN ISSUE WITH 2010 PRIUS. TOYOTA IDENTIFIED THE ISSUE IN A PREVIOUS QUALITY CAMPAIGN BUT ONLY REPAIRED IF BRAKES FULLY FAILED. BRAKE FAILURE IS WHAT IT TOOK TO HAVE YOUR CAR REPAIRED?

ABS, TRACTION, AND BRAKE LIGHT STAY ON. IT IS THE ACTUATOR BRAKE AND THE COST TO FIX IS OVER $2000. I HAVE RESEARCHED THIS ISSUE WITH OTHER 2010 PRIUS' AND IT IS A COMMON ISSUE. THIS IS A DEFECT THAT TOYOTA REFUSES TO FIX EVEN THOUGH IT IS VERY COMMON AND PUTS MANY PEOPLE AT RISK.

ON TUESDAY, FEBRUARY 23, OUR BRAKING SYSTEM FAILED ON OUR TOYOTA PRIUS WHILE DRIVING ON A SIDE ROAD AFTER MONTHS OF CONTINUING WEAKNESS IN THE BRAKE PEDAL AND "LURCHING" WHEN BRAKING OVER POTHOLES. THE BRAKE SYSTEM LOST HYDRAULIC PRESSURE. UPON INSPECTION BY AN ASE-CERTIFIE MECHANIC, THEY DETERMINED THE BRAKE BOOSTER ASSEMBLY HAD LIKELY FAILED, BUT RECOMMENDED SENDING TO A TOYOTA DEALERSHIP. THEY CONFIRMED THE VEHICLE WAS UNFIT TO DRIVE. THE VEHICLE WAS SENT TO A TOYOTA DEALER. THE DEALER CONFIRMED THE BREAK BOOSTER ASSEMBLY/ACTUATOR HAD FAILED. THE DEALER ADVISED THE BRAKE BOOSTER HAD PREVIOUSLY BEEN UNDER A TOYOTA "CUSTOMER SERVICE CAMPAIGN," BUT THAT THE "WARRANTY" CAMPAIGN HAD EXPIRED. HOWEVER, HE ADVISED TOYOTA BRAND ENGAGEMENT CENTER HAS OFTEN ASSISTED CUSTOMERS WHEN THEY'RE JUST OUTSIDE THE WARRANTY PERIOD. WHEN CONTACTING TOYOTA, THEY STATED THIS VEHICLE WAS NEVER UNDER RECALL AND WAS NOT ELIGIBLE, BUT THEN SAID THEY SENT INFORMATION ON A TOYOTA SAFETY CAMPAIGN. UPON RESEARCH, WE CONTINUED TO CONFIRM THAT THE DIAGNOSIS WAS TIED TO RECALL D0H FROM JULY 2013. WE'VE ALSO REVIEWED OUR VEHICLE HISTORY, AND THE BRAKE PUMP ASSEMBLY WAS NEVER REPLACED DESPITE BEING INSPECTED CONSISTENTLY BY TOYOTA DEALERS SINCE 2013 AND UNDER RECALL. TOYOTA HAS DECLINED TO COVER THE COST OF THE REPLACEMENT FOR THE BRAKE PUMP ASSEMBLY. THE COST OF REPAIR IS NEARLY THE SAME AS THE CURRENT VALUE OF THE VEHICLE. TOYOTA BRAND ENGAGEMENT CENTER HAS DECLINED TO PROVIDE THIS INFORMATION IN WRITING, WOULD NOT PROVIDE A NAME, AND OTHERWISE ACTED COMPLETELY SKETCHY - FOR LACK OF A BETTER WORD - ANY TIME WE TRIED TO CLARIFY THE REPAIR WAS CLEARLY TIED TO THE JUNE 2013 RECALL. WE WERE VERY, VERY FORTUNATE THE BRAKES FAILED ON A SIDE STREET NEAR OUR HOME, NOT ON A HIGHWAY OR OTHER HIGH-RISK AREA. WE WOULD LIKE TOYOTA TO HONOR THE RECALL, EXTEND IT FOR OTHER CUSTOMERS, AND COVER THE COST OF REPAIR.

IT CAME UP WITH C1391 AND I LOOK THAT CODE UP AND IT COMES UP WITH THAT CODE IS A COMMON ISSUE WITH THE PRIUS. I READ THAT IT COULD LEAD TO BRAKE FAILURE.

TOYOTA BRAKE BOOSTER PUMP HAS FAILED DUE TO MANUFACTURING DEFECTS, WHICH AFFECTED THE STOPPING OF THE VEHICLE. TOYOTA HAS ISSUED RECALL FOR THIS PROBLEM BUT ONLY FOR LATEST MODELS (2019 AND LATER). I'VE CALLED TO TOYOTA AND THEY REFUSED TO ADDRESS THIS PROBLEM. I LOOKED UP ON INTERNET AND FOUND THIS IS A WIDE SPREAD PROBLEM EXPERIENCED BY MANY OWNERS OF PRIUSES. TOYOTA MUST ISSUE THE RECALL FOR ALL THE VEHICLES AFFECTED, NOT THE LATEST ONES ONLY.

WAS GOING 25 MPH YESTERDAY NOVEMBER 22, 2020 EVENING WHEN 4 (BRAKE, ABS, TRACTION & CAUTION) LIGHTS CAME ON DASHBOARD. PULLED OVER THE SHOULDER & TURNED IGNITION OFF. RESTARTED LATER & 4 LIGHTS STILL ON. FOLLOWING DAY, WENT TO DEALERSHIP & WAS TOLD BRAKE BOOSTER ASSEMBLY NEED TO BE REPLACED DUE TO INTERNAL FLUID LEAK.

I HAVE EXPERIENCED PROBLEMS WITH THE ELECTRICAL, OIL, AND BREAK SYSTEMS EVER SINCE PURCHASING MY CERTIFIED PRE-OWNED 2010 PRIUS FROM THE DEALERSHIP IN 2013. TOYOTA HAS NEVER PROVIDED A SATISFACTORY ANSWER FOR WHAT IS ACTUALLY WRONG WITH THE ELECTRICAL SYSTEM; THE PROBLEM STILL REMAINS. TOYOTA ALSO DOES NOT HAVE AN IDEAL MAINTENANCE PLAN SET UP FOR THE KNOWN INCREASED OIL CONSUMPTION RATE THAT IS DIRECTLY LINKED TO MY MODEL VEHICLE AND HAS NOT ONLY NOT PERFORMED ROUTINE OIL CHANGES BUT ALSO SENT ME HOME AFTER A SUPPOSED OIL CHANGE WITH ZERO OIL IN MY TANK. BUT TODAY MY MAIN CONCERN THAT I TAKE ISSUE WITH AND THAT IVE ENCOUNTERED FROM THE GET-GO, HAS TO DO WITH THE BREAKS. FOR YEARS I'VE BEEN TELLING TOYOTA ABOUT HOW MY BREAKS DO THIS THING WHERE UNDER THE RIGHT CIRCUMSTANCES (THOSE BEING THINGS LIKE SLIGHT BUMPS OR RAISES IN THE ROAD, OR GOING OVER A MANHOLE COVER) THE BREAKS NOT ONLY GIVE OUT BUT ACTUALLY PROPEL ME FORWARD WITH ZERO CHANCE FOR STOPPING WHICH IS QUITE TERRIFYING ALREADY AND THEN WHEN YOU ADD IN OTHER DRIVERS ON THE ROAD INTO THE EQUATION IS A LITERAL NIGHTMARE. DESPITE MY MANY EFFORTS FOR TOYOTA TO TAKE A LOOK AT THEM THEY ALWAYS REFUSE ANY SERVICE TO THEM BECAUSE MY DASHBOARD IS NOT DISPLAYING ANY WARNING SIGNS. ALSO, DUE TO THE FACT THAT ITS NOT A CONSTANT ISSUE, MEANING IT ONLY HAPPENS UNDER THE RIGHT CIRCUMSTANCES WHICH IDK WHERE SUCH A PRECISE PLACE EXISTS NEAR THE DEALERSHIP, THEY CANT EXPERIENCE IT FOR THEMSELVES. SO MY CONCERNS ARE DISMISSED LEAVING ME TO FEND FOR MYSELF WHENEVER THESE CIRCUMSTANCES ARISE WHICH NO DOUBT AN ACCIDENT SEEMS TO BE ON THE HORIZON. THEN WITH ~114,700 MILES ON THE ODOMETER, MY ENTIRE ABS SYSTEM CRASHED WHILE I WAS IN TRAFFIC. LUCKILY I AM A BEYOND EXCEPTIONAL DRIVER AND ALSO HAVE CATLIKE REFLEXES SO WAS ABLE TO MANAGE MY WAY TO THE SHOULDER OF THE ROAD WHEN THIS OCCURRED. HOWEVER, WITH WARNING LIGHTS NOW ILLUMINATED O

UPON STARTING THE CAR, THE ABS, BRAKE AND TRACTION CONTROL LIGHTS ALL CAME ON. CHECKED BRAKE FLUID AND IT WAS AT MAX LEVEL. TOOK TO DEALER AND SHOWED CODE 1391 WHICH SHOWED THE BRAKE BOOSTER AND BOOSTER PUMP ASSEMBLIES NEED REPLACING. IT'S A KNOWN PROBLEM WITH TOYOTA. A VOLUNTARY RECALL WAS ISSUED FOR OUR 2010, BUT MY SPECIFIC MODEL WASN'T INCLUDED AND RECALL EXPIRED IN 11/19 OR 150K MILES. I'M AT 150,992. THERE IS ACTIVE RECALL FOR SAME ISSUE FOR 2011-2015 MODELS. IT'S A KNOWN SAFETY ISSUE AND THEY REFUSE TO FIX IT. IT'S A $3K JOB TO REPAIR FOR A CAR THAT IS WORTH ABOUT DOUBLE THAT. WHEN THIS WARNING COMES UP, YOUR BRAKING SYSTEM IS NOT RELIABLE. HAD THIS HAPPENED WHILE DRIVING, AN ACCIDENT COULD HAVE OCCURRED. TOYOTA KNOWING THIS IS A SAFETY ISSUE NEEDS TO CORRECT IT ON ALL MODELS THAT SHOW THIS WARNING, NOT JUST SELECT MODELS.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DEPRESSING THE BRAKE PEDAL, THE BRAKE PEDAL WAS FIRM CAUSING THE BRAKING DISTANCE TO BE EXTENDED. THE VEHICLE WAS TAKEN TO TOYOTA OF LINCOLN PARK LOCATED AT 1561 N FREMONT ST, CHICAGO, IL 60642 WHO DIAGNOSED THE VEHICLE AND DETERMINED THAT THE BRAKE BOOSTER AND MASTER CYLINDER WERE DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 100,000. THE VIN WAS NOT AVAILABLE.

I WENT TO THE DEALER AS I WAS TOLD AFTER OPENING A CASE WITH TOYOTA,, HOWEVER THE SOLUTION WAS NOT RESOLVED TO MY SATISFACTION. BASICALLY. SAFETY PARTS WERE REPLACED FROM A RECALL ON 08/2013. A FEW YEARS LATER I GOT ANOTHER TOYOTA NOTIFICATION THAT IF I HAD THESE BRAKE BOOSTER RELATED FAILURES/LIGHTS TO BRING IT IN, I WOULD HAVE EVEN IF I HAD THE LIGHTS WITHOUT THE NOTIFICATION. THE OTHER DAY I HAD THE FAILURE RELATED TO THE DEFECTIVE PARTS INSTALLED ON 08/2013. SO SOMEWHERE BETWEEN 08/2013 AND WHEN TOYOTA NOTIFIED ME ABOUT THE LIGHTS OR THE STILL EXISTING DEFECT, THAT THERE WAS A DEFECT GOING TO HAPPEN BUT DID NOT KNOW WHEN AND TODAY I HAD THE FAILURE. I BELIEVED THAT SINCE I HAD THE ORIGINAL REPLACEMENT BRAKE SAFETY PARTS REPLACED THAT I WAS DRIVING A SAFE PRIUS. I FEEL THE SECOND REPAIR FOR THE SAME PARTS SHOULD BE COVERED SINCE WHEN THEY NOTIFIED ME THEY KNEW THERE WAS A DEFECT AND CHOSE NOT TO ABSORB THE COST OF THIS REMEDY.

THE BRAKE LEVELS WERE FINE, HOWEVER AFTER TAKING THE CAR INTO THE DEALER, I WAS NOTIFIED THAT THE BREAK BOOSTER FAILED AND NEEDED TO BE REPLACED. AFTER RESEARCH, IT APPEARS THAT THERE WAS A RECALL FOR THIS PART IN 2013, AS WELL AS A RECENT LEGAL SUIT SUGGESTING THAT TOYOTA DID NOT INCLUDE ALL VEHICLES THAT COULD BE AFFECTED BY THIS FAULTY PART (ISSUE TYPICALLY SHOWS UP AROUND 150K MILES). I HAVE A 2010 PRIUS ( INCLUDED IN THE SUIT) WITH JUST ABOVE 150K AND WAS NEVER NOTIFIED.

VEHICLE HAS APPROXIMATELY 120,000 MILES. WHILE DRIVING THROUGH TOWN OR ON THE HIGHWAY, OUR VEHICLE WILL INTERMITTENTLY LOSE REGENERATIVE BRAKING. DURING THESE INSTANCES, THE BRAKE PEDAL SOFTENS AND GREATER EFFORT MUST BE EXERTED TO SLOW AND STOP THE CAR. SOMETIMES MINUTES... AT OTHER TIMES THE NEXT DAY AFTER THE CAR HAS SAT IN THE GARAGE, THE INDICATOR LIGHTS WILL ALL TURN OFF AND REGENERATIVE BRAKING RESUMES NORMALLY. THIS CREATES A VERY UNSAFE SITUATION AS IT CAN BE UNPREDICTABLE HOW MUCH PRESSURE TO APPLY TO THE BRAKES. THIS IS BEEN NOTICED AT SLOW SPEEDS, HIGHWAY SPEEDS, IN TURNS, OR TRAVELING IN A STRAIGHT LINE. THE VEHICLE WAS DIAGNOSED AND DETERMINED TO HAVE A FAULTY BRAKE BOOSTER/ACTUATOR. THIS HAS CREATED AN UNSAFE AND UNRELIABLE SITUATION FOR TRANSPORTING MY FAMILY. WHAT IS QUITE CONCERNING IS THAT THIS OCCURRED WITH THE 2ND GENERATION PRIUS AND TOYOTA EXTENDED A HELPING HAND BY ISSUING A RECALL OR WARRANTY ENHANCEMENT. HOWEVER, MY VEHICLE WAS PRODUCED JUST MONTHS OUTSIDE OF THE 13V235000 RECALL WINDOW, YET EXPERIENCES THE SAME DANGEROUS DRIVING EXPERIENCE AS THOSE WHO WERE INCLUDED IN THE RECALL. TOYOTA NEEDS TO DO THE RIGHT THING AND THE SAFE THING BY RECALLING ADDITIONAL 3RD GENERATION PRIUS VEHICLES AND REPAIR OR REPLACE ALL FAULTY COMPONENTS BEFORE MORE CRASHES AND INJURIES OCCUR.

PREVIOUS RECALLS FOR A 2010 TOYOTA PRIUS (NHTSA CAMPAIGN NUMBER: 13V235000) AND A 2019 TOYOTA CUSTOMER SUPPORT PROGRAM (CSP ZJB) HAS ACKNOWLEDGED AN UNSAFE FAILURE MODE IN THE VEHICLE WHERE THE BRAKE BOOSTER ASSEMBLY FAILS DUE TO HIGH PRESSURE AND CAUSES THE AUTOMOBILE TO HAVE DIFFICULTY STOPPING. ON SEPTEMBER 4, 2020 WHILE DRIVING DOWN THE ROAD AT ROUGHLY 40 MPH, I EXPERIENCED INDICATION LIGHTS CONSISTENT WITH THE DESCRIPTIONS OUTLINED IN THE SAFETY RECALL AND TOYOTA SUPPORT PROGRAM. MY AUTOMOBILE ALSO HAD EXTREME DIFFICULTY COMING TO A STOP FROM 40 MPH AND I HAD TO UNSAFELY PULL TO THE SHOULDER OF THE ROAD AT SPEED TO AVOID COLLIDING WITH THE AUTOMOBILE IN FRONT OF ME. THE TOYOTA CSP ZJB DOES NOT COVER MY VEHICLE DUE TO TIME AND MILEAGE OF THE VEHICLE, BUT I FEEL THIS SAFETY CRITICAL SYSTEM SHOULD HAVE BEEN REPLACED PRIOR TO ME EXPERIENCING A FAILURE. TOYOTA SELECTIVELY ONLY REPLACED BRAKE BOOSTER ASSEMBLIES OUTLINED IN THE RECALL AND THE CSP, IF THE AUTOMOBILE WAS EXPERIENCE ISSUES. TOYOTA STOPPED SHORT OF PREVENTATIVE SAFETY MEASURES OF REPLACING THIS ASSEMBLY PRIOR TO FAILURE, LEADING TO AN ALMOST COLLISION EVENT FOR ME. INDEPENDENT RESEARCH HAS IDENTIFIED THIS ISSUE HAS BEEN RESPONSIBLE FOR OTHER TOYOTA PRIUS ACCIDENTS LEADING ME TO BELIEVE THIS IS A SAFETY ISSUE THAT SHOULD BE ADDRESSED BY THE NHTSA BEFORE OTHERS EXPERIENCE A CRITICAL SAFETY FAILURE AT NO FAULT OF THEIR OWN.

I WAS COMFORTABLY DRIVING MY 2010 TOYOTA PRIUS DOWN A CITY STREET ON A THURSDAY AFTERNOON--ABOUT 25 MPH, LIGHT TRAFFIC--WHEN SUDDENLY--WITHOUT ANY TRIGGER OR WARNING--I LIGHTLY PRESSED DOWN THE BRAKE PEDAL TO SLOW DOWN FOR A SPEED BUMP, AND THE BRAKES SHUDDERED, THE BRAKE PEDAL SEEMED TO TWITCH, AND THE CAR STARTED MAKING A LOUD SHRIEKING AND GRINDING NOISE EVERY 3-5 SECONDS. FOR THE RECORD, MY 2010 TOYOTA PRIUS HAS BEEN REGULARLY SERVICED AT MY LOCAL TOYOTA DEALERSHIP SINCE I PURCHASED IT IN 2018. THE LOUD SHRIEKING FELT LIKE IT WAS COMING FROM BELOW MY FEET AND FROM THE DRIVE SHAFT. I PULLED OVER--THE SHRIEKING AND GRINDING CONTINUED. I STOPPED THE CAR--THE SHRIEKING AND GRINDING CONTINUED. I GOT OUT OF THE CAR--THE SHRIEKING AND GRINDING SLOWED AFTER A FEW MINUTES. WHEN I TURNED THE CAR ON AGAIN, THE SHRIEKING AND GRINDING STARTED AND THE CAR WAS BEEPING IN A WAY I'D NEVER HEARD BEFORE. FORTUNATELY, I WAS ABOUT 4 BLOCKS FROM MY LOCAL TOYOTA DEALERSHIP. I ASKED THEM IF I WAS SAFE TO DRIVE THE FOUR BLOCKS OR IF I SHOULD GET THE CAR TOWED, AND THEY SAID I SHOULD BE SAFE TO DRIVE. I DROVE TO THE DEALERSHIP WITH THE CAR SHRIEKING AND BEEPING. THE BRAKES FELT SQUISHY AND UNRELIABLE, BUT THE DEALERSHIP HAS SAID I SHOULD BE FINE. I DROPPED OFF THE CAR. THE NEXT DAY, I GOT A CALL FROM THE DEALERSHIP SAYING THAT MY BRAKE BOOSTER PUMP AND BRAKE CYLINDER ASSEMBLY HAD TOTALLY FAILED. WHEN I ASKED THE TECHNICIAN IF THERE WAS SOMETHING I COULD HAVE DONE TO PREVENT THIS, HE SAID, 'NO, THIS IS JUST SOMETHING THAT HAPPENS TO THESE CARS.' THE BRAKE FAILURE OCCURRED ON THURSDAY, AUGUST 27, 2020. THE PHONE CALL FROM THE DEALERSHIP OCCURRED ON FRIDAY, AUGUST 28, 2020.

HAD THE TROUBLE CODE READ AND THE STORE READ THE DIAGNOSTIC TROUBLE CODE AS C1391 AND RESET SO I COULD DRIVE THE VEHICLE SLOWLY HOME.

OFTER WHEN THE LIGHTS ARE ON, THE BRAKES FEEL SPONGY, OR AS THOUGH THEY MAY NOT STOP THE CAR. I TOOK THE CAR TO THE TOYOTA DEALERSHIP AND THEY CONCLUDED THAT THE MASTER CYLINDER AND OTHER PARTS NEEDED REPLACING. I FOUND OUT THAT TOYOTA HAS HAD LOTS OF PROBLEMS WITH THESE BRAKE CYLINDERS.

I EXPERIENCED A SIGNIFICANT LOSS OF BRAKE PERFORMANCE ACCOMPANIED BY MANY WARNING LIGHTS ON THE DASHBOARD, INCLUDING ONE THAT INDICATED A PROBLEM WITH THE ABS BRAKE SYSTEM IN MY 2010 PRIUS. UPON IMMEDIATELY TAKING THE CAR TO THE DEALERSHIP, I WAS TOLD THAT TOYOTA EXTENDED A WARRANTY PROGRAM (ZJB & ZKK) FOR THE SOURCE OF THE PROBLEM ABS BRAKE ACTUATOR/MASTER CYLINDER FAILURE, BUT THAT I WAS NOT ELIGIBLE FOR THE WARRANTY COVERAGE BECAUSE THE DEADLINE HAD EXPIRED. MY CAR WAS UNDER 150,000 MILES, AS REQUIRED BY THE WARRANTY, AND DISPLAYED THE CORRECT FAILURE CODE AS REQUIRED BY THE WARRANTY. BUT, SINCE MY CAR DID NOT EXPERIENCE THE PROBLEM OR DISPLAY AN ERROR CODE BEFORE THE END OF FEBRUARY 2020, I WAS TOLD THAT I WAS INELIGIBLE. I WAS INFORMED THAT I WOULD HAVE TO PAY OVER $4100 FOR A REPAIR THROUGH THE DEALERSHIP, BUY A NEW CAR OR TAKE MY CHANCES AND DRIVE THE CAR 'AS IS' UNTIL I COULD FIND A CHEAPER SOLUTION. THE CHEAPER SOLUTION WOULD BE TO FIND ANOTHER ABS UNIT AT A SALVAGE YARD, AND HAVE A NON-TOYOTA CERTIFIED MECHANIC INSTALL IT. THERE IS NOTHING TO INDICATE A SALVAGE YARD UNIT WILL NOT SIMPLY FAIL AGAIN. I WAS WELL WITHIN THE 150,000 MILE LIMIT OF THE WARRANTY. SO, I AM TO ACCEPT RESPONSIBILITY FOR THE REPAIR OF A PART THAT TOYOTA ADMITS IS FAULTY, AND WOULD HAVE REPLACED IF THE PROBLEM WOULD HAVE SURFACED A MERE SIX MONTHS EARLIER? I BELIEVE TOYOTA'S WARRANTY EXTENSION TO BE A MEAGER ATTEMPT AT APPEASING THE NHTSA AND OTHER AUTHORITIES SO THEY DO NOT HAVE TO LAUNCH A FULL SCALE RECALL. THEY ARE ENDANGERING THE LIVES OF HUNDREDS OF THOUSANDS OF PEOPLE WHO DEPEND ON THESE CARS ON A DAILY BASIS, AS THEY SHOULD NOT ASK THEIR CUSTOMERS TO EXPERIENCE A MAJOR BRAKE FAILURE BEFORE THE MANUFACTURER WILL AGREE TO FIX A KNOWN PROBLEM (OR NOT FIX IT, RATHER, AS THE TIME LIMIT HAS EXPIRED). TOYOTA IS PUTTING PROFITS AHEAD OF SAFETY, DURING A PANDEMIC. I THE NHTSA TO HELP US.

I DECELERATED VEHICLE USING ENGINE POWER THEN APPLIED BRAKES. BRAKE PEDAL DEPRESSED APPROX. 3/4 TRAVEL (MUCH FURTHER THAN NORMAL) BEFORE BRAKING ACTION FELT. I STOPPED VEHICLE, RECYCLED POWER AND WARNING LIGHTS REMAINED ILLUMINATED AND BRAKE RESPONSIVENESS WAS UNCHANGED. UPON REACHING DESTINATION, I DOWNLOADED ERROR CODE (C1391) THEN CALLED LOCAL TOYOTA SERVICE CENTER. INFORMED THAT ENHANCED WARRANTY LETTER ZJB ADDRESSED THIS ISSUE, HOWEVER COVERAGE EXPIRED 6 WEEKS AGO. SERVICE CENTER DIRECTED ME TO TOYOTA CUSTOMER CARE. TOYOTA CUSTOMER CARE CONFIRMED THAT THE REPAIR COVERAGE HAD RECENTLY EXPIRED AND THEY WERE NOT ABLE TO OFFER ANY ASSISTANCE WHATSOEVER. DUE TO THE GLOBAL PANDEMIC, MY DRIVING HAD BEEN SEVERELY CURTAILED SINCE MARCH. NOW JULY, A REQUIRED WORK TRIP LED TO THIS MALFUNCTION. THIS ISSUE SHOULD BE CLASSIFIED AS A RECALL AND NOT A WARRANTY WITH AN EXPIRATION. A MAJOR, FLEE-WIDE BRAKING ISSUE SHOULD REQUIRE THE MANUFACTURER TO REPAIR.

CUSTOMER SUPPORT PROGRAM "ZJB" WAS CREATED BY TOYOTA NORTH AMERICA FOR THIS ISSUE IN RESPONSE TO THOUSANDS OF PRIUS MODELS EXPERIENCING THIS SEVERE MALFUNCTION, HOWEVER, MY 2010 PRIUS IS NO LONGER ELIGIBLE FOR COVERAGE FOR THIS REPAIR, EVEN THOUGH OTHER PRIUS MODELS ARE STILL ELIGIBLE FOR COMPLETE COVERAGE FOR THIS REPAIR. THIS IS A SAFETY HAZARD AND TOYOTA NORTH AMERICA NEEDS TO STAND BY COVERAGE FOR THIS GRAVE MALFUNCTION FOR ALL MODELS REGARDLESS OF YEAR OR MILEAGE.

MY BRAKES ENDED UP LOCKING UP AND NOT WORKING, AND MY BATTERY IN MY CAR DIED BECAUSE IT WAS THE BRAKE SYSTEM WAS NOT ABLE TO RECHARGE MY BATTERY. EVEN THOUGH I STARTED HAVING ISSUES WITH IT IN FEBRUARY, APPARENTLY TOYOTA SAID THAT BECAUSE I HAD A 2010 PRIUS, THAT SINCE NOVEMBER 31, 2019 HAD PASSED, THE RECALL/EXTENDED WARRANTY "RAN OUT" ON IT. EVEN THOUGH THIS IS A PROBLEM THAT OBVIOUSLY WASN'T FIXED IN THE FIRST PLACE. SO WHEN I TOOK IT TO THE DEALERSHIP TO GET A DIAGNOSTICS RAN ON IT, THEY SAID THAT THEY NEEDED $3,200 TO FIX THE VEHICLE. THIS INCLUDED BOTH THE PURCHASING AND INSTALLATION OF A NEW BRAKE BOOSTER/MASTER CYLINDER ASSEM AND AN ABS PUMP MOTOR ASSEM. I OBVIOUSLY DO NOT HAVE THE MONEY FOR THE REPAIR AND THEY ARE TELLING ME TO GO KICK ROCKS. THIS IS NOT RIGHT AND BECAUSE OF THE BRAKE ISSUE NOT BEING FIXED IN THE FIRST PLACE, IT THEN ALLOWED MY BATTERY (WHICH RUNS AROUND $1,500) TO GET COMPLETELY DRAINED AND PREVENTED IT FROM BEING PROPERLY RECHARGED BY THE BRAKE SYSTEM. *TR

BRAKES AND VDC SYSTEM CONSTANTLY ENGAGE DURING U-TURNS, TIGHT TURNING CIRCLES, CAUSING THE CAR TO BRAKE UNEXPECTEDLY. WHILE NOT ACCIDENT HAS HAPPENED, IT HAS CAUSED A FEW NEAR MISSES AS MY WINDOW TO TURN SHRINKS BECAUSE THE CAR IS BRAKING. *TR

MECHANIC INFORMED ME THAT THIS ISSUE WAS PREVIOUSLY UNDER SAFETY RECALL AND MY VEHICLE HAD THE PROPER REPAIRS DONE, CLEARLY THIS IS AN ONGOING SAFETY ISSUE WITH THIS VEHICLE THAT IS NOT BEING PROPERLY ADDRESSED BY TOYOTA. IT IS ALSO AN EXTREMELY EXPENSIVE REPAIR WHICH TOYOTA NEEDS TO BE FINANCIALLY RESPONSIBLE FOR. *TR

ON FRIDAY, MAY 15 2020 I TURNED ON MY CAR AND SAW ABS, BRAKE AND VEHICLE TRACTION LIGHTS ILLUMINATED. THE BRAKE PEDDLE ALSO FELT ODD. WITHIN 30 MINUTES I TOOK IT TO MY LOCAL TOYOTA DEALER. THE SERVICE WRITER HAD A CLEAR IDEA OF WHAT WAS HAPPENING AS SHE SAID THIS HAS BEEN HAPPENING A LOT TO PRIUS MODELS. SURE ENOUGH THE DIAGNOSTIC CODE C1391. I WAS TOLD I NEEDED TO REPLACE THE BRAKE BOOSTER/PUMP ASSEMBLY WHICH WOULD COST ME $3,000! UPON RESEARCH, MY CAR WAS COVERED UNDER A TSB TILL NOVEMBER 30, 2019, BUT ONLY IF THEY FAILED. THERE WAS NO RECALL ISSUED BY TMS TO PRO-ACTIVELY FIX A KNOWN BRAKE DEFICIENCY. MY CAR HAS 159,000 MILES, I HAVE NEVER HAD ANYONE SERVICE MY VEHICLE BESIDES TOYOTA DEALERSHIPS (EXCEPT TIRES). I CALLED TMS TO CORPORATE TO SEE IF I COULD BE OFFERED ASSISTANCE, BUT WAS FLAT OUT DENIED (I CAN PROVIDE THAT CASE NUMBER IF NEEDED).I FIND IT ODD THAT TOYOTA BEGAN PHASE2 ON 2011-2015 FOR SAME ISSUE THAT LASTS TILL APRIL 2021. IT IS UNSETTLING THAT IF TOYOTA KNOWS ABOUT THE BRAKE BOOSTER AND PUMP PROBLEMS, WHY THEY DON'T HAVE A RECALL, BUT RATHER A WAIT AND SEE IF IT FAILS UNDER THEIR 'SECONDARY/ENHANCED WARRANTY'. UPSET THAT IF THIS HAPPENED 5 MONTHS AGO, THIS WOULD HAVE FALLEN UNDER THEIR GUIDELINE TO REPAIR.

LOCAL DEALERSHIP WOULDN'T DO ANYTHING UNTIL IT REGISTERED THE CODE AGAIN. THE DEALERSHIP SERVICE ADVISOR, SAID UNTIL THE CODE IS TRIGGERED AGAIN THEY WOULDN'T DO ANYTHING.

WHEN I RESEARCHED THIS,I FOUND THAT IT IS A KNOWN PROBLEM TOTOYOTA AND THEY DID A VOLUNTARY RECALL. MY QUESTION IS WHY WOULD THERE BE A VOLUNTARY RECALL ON A PART THAT IS VITAL TO THE SAFETY OF THE CAR AND HAS A KNOWN DEFECT? BECAUSE IT WAS A VOLUNTARY RECALL THEY COULD ARBITRARILY SELECT A CUT OFF (150,000 MILES) INSTEAD OF ENSURING THE CAR WAS SAFE. THIS IS ONLY FOR 2010 PRIUS.

TOYOTA PREVIOUSLY ACKNOWLEDGED THIS FAULTY PART BUT CLAIMS THAT I MISSED THE DEADLINE BY 35 DAYS TO GET IT FIXED. THE REPAIR COSTS ROUGHLY $4,000 WHICH TOYOTA HAS REFUSE DO TO ACCEPT RESPONSIBILITY FOR. I CANNOT AFFORD TO FIX THIS AND BELIEVE THAT IT IS IRRESPONSIBLE FOR TOYOTA TO PUT THEIR PROFITS ABOVE THE SAFETY OF ITS' CUSTOMERS. I DO NO THIS BELIEVE THAT IT IS ETHICAL TO PUT A DEADLINE ON A SAFETY CONCERN OF THIS NATURE.

I BOUGHT THIS CAR AROUND MID YEAR OF 2019, AND WHEN I FIRST USED IT IN THE HIGHWAY COMING BACK FROM WORK, THERE WAS TRAFFIC AND I NOTICED THE BREAKS NOT RESPONDING WELL. THIS HAS HAPPENED MANY TIMES SINCE I BOUGHT IT, IN THE STREETS AS WELL. THERE'S ALSO A ORANGE LIGHT SAYING THAT IT NEEDS MAINTENANCE. I HAVE TAKEN THE CAR ABOUT 3 TIMES TO THE PERSON THAT SOLD IT TO ME BECAUSE HE HAS A CAR SHOP AND IT STILL DOES THE SAME THING.

WHILE DRIVING BACK FROM RUNNING ERRANDS MY CAR'S LIGHTS ON THE DASHBOARD STARTED TO COME ON AND NOISES STARTED TO START HAPPENING. I WAS LUCKY I WAS ONLY A FEW STREETS AWAY FROM MY HOUSE SO I DECIDED TO DRIVE BACK HOME. THE BREAK WAS REALLY HARD TO PRESS. THE BRAKE FELT LIKE IT WAS A ROCK AND HARD TO PRESS. I DROVE WITH MY HAZARDS ON UNSURE OF WHAT COULD HAPPEN WHILE DRIVING. THERE WAS SOMETHING WRONG AND THE CAR STARTED TO BEEP AND I WAS WORRIED THE CAR MIGHT FAIL TO BRAKE SO I STARTED TO DRIVE VERY SLOWLY. THE BRAKES WERE SO HARD TO PRESS. I TOOK MY CAR TO TOYOTA THE NEXT DAY AND THEY SAID THERE WAS A DEFECT WITH MY BRAKES. THEY HAD THE VEHICLE FOR A FEW DAYS AND RETURNED TO ME SAYING IT WAS FIXED. NEEDLESS TO SAY THIS WAS A VERY SCARY SITUATION TO BE IN. I DRIVE A LOT. IF I HAD BEEN FURTHER AWAY FROM MY HOME THIS WOULD HAVE PUT ME IN A VERY DANGEROUS POSITION. I COULD'VE BEEN STRANDED OR DROVE ON THE FREEWAY IN THIS CONDITION UNSURE OF WHAT WAS HAPPENING. MY CAR COULD'VE STOPPED BRAKING, I COULD'VE GOTTEN INTO A BIG ACCIDENT AND INJURED OTHER DRIVERS AROUND ME. THIS IS A VERY SERIOUS ISSUE THAT SHOULD BE RECALLED NOW AND SAVE OTHER DRIVERS! IN CALIFORNIA PEOPLE DRIVE UP TO 80 MPH ON THE HIGHWAY-IF WE ARE BEHIND A CAR AND THE BRAKES MALFUNCTION YOU CAN IMAGINE WHAT WILL HAPPEN TO THE DRIVER AND ANYONE INVOLVED! WHEN I HEARD TOYOTA WAS NOT RECALLING THIS ON ALL PRIUS'S THAT MIGHT BE AFFECTED IT REALLY SCARED ME. THIS IS UNSAFE.

THIS SHOULD BE A RECALL NOT AN EXTENDED WARRENTY. MY BRAKES BARK AND PUSH BACK EVERY TIME I BRAKE. THIS DOESN'T SEEM SAFE TO DRIVE ON THE FREEWAY AND NOT GOOD IF AN ACCIDENT INCURS BECAUSE I HAD TO WAIT UNTIL MY BRAKES DIDN'T WORK. PLEASE MAKE A RECALL AND NOT JUST AN EXTENDED WARRENTY.

I AM ENTERING THIS COMPLAINT BASED ON READING DOZENS OF ACCOUNTS THAT RESEMBLE MY ISSUE EXACTLY. TEN MINUTES INTO A FORTY MINUTE DRIVE THREE LIGHTS SUDDENLY CAME ON, THE BRAKE, ABS AND TRACTION CONTROL LIGHTS. THE BRAKES IMMEDIATELY BECAME SOFT, REQUIRING 50-60% MORE EFFORT TO STOP THE CAR AND DRASTICALLY REDUCED STOPPING TIME. THIS OCCURRED ON A DARK COUNTY ROAD, AFTER A LIGHT SNOWFALL AND TEMPERATURES IN THE MID-20'S. I QUICKLY PULLED INTO A CHURCH PARKING LOT TO CHECK THE BRAKE FLUID LEVEL AND FOR ANY BROKEN BRAKE LINES. I ALSO SHUT OFF THE CAR HOPING TO CLEAR THE ERROR, WHICH IT DID NOT. FLUID LEVELS LOOKED NORMAL AND I DECIDED TO PROCEED THE REMAINING 25 MILES OF MY DRIVE AFTER ENSURING THAT I COULD STOP AS NEEDED. AFTER 20 MINUTES OF DRIVING 45-55MPH THE LIGHTS TURNED OFF AND BRAKING POWER WAS INSTANTLY RESTORED TO 100%. I HAVE NOT TAKEN MY CAR INTO THE DEALER YET, BUT PLAN ON NOTIFYING THEM.

I WAS DRIVING TO MY HOUSE AND THE BRAKE PEDAL WENT TO THE BOTTOM. SEVERAL LIGHTS APPEARED ON THE DASHBOARD. I WAS DRIVING IN THE HIGHWAY AND FORTUNATELY THERE WAS AN EXIT AND I COULD GET OUT OF THE HIGHWAY AND I MANAGE HOW TO STOP AND I DID NOT CRASH. THE STORY COULD BE ANOTHER IF I WAS DRIVING FASTER. THE NEXT DAY I TOOK IT TO THE TOYOTA DEALER AND THEY TOLD ME THAT THE PROBLEM WAS THE BOOSTER PUMP (ATTACHED YOU CAN FIND THE ESTIMATE). I WAS SHOCKED WHEN I FOUND HOW MUCH WAS GOING TO COST ME. MY CAR HAS NEVER HAD A PROBLEM AND ALL OIL CHANGES HAD BEEN AT THE SAME TOYOTA DEALER. I HAVE NEVER TAKEN THE CAR ANYWHERE ELSE. INVESTIGATING I FOUND THAT THIS MODEL PRIUS 2010 IN 2013 HAD A RECALL FOR THIS SAME PROBLEM AFFECTING 82000 PEOPLE.

BRAKE PEDAL GOES TO FLOOR. BRAKE LIGHT IS ON. DEALER SAYS ACCUMULATOR PUMP IS BAD. THERE IS A RECALL FOR THIS ITEM. THEY REPLACED IT UNDER RECALL IN 2014 AND REFUSE TO DO IT AGAIN. QUOTED $2000 TO REPAIR. CALLED TOYOTA CUSTOMER SERVICE AND THEY WON'T DO ANYTHING EITHER. IT IS A SAFETY ISSUE AND STILL HAVING THE SAME SAFETY ISSUES IS NOT OK.

I TOOK MY PRIUS TO THE DEALER BECAUSE THE BRAKE LIGHT WAS ON, TO RESOLVE THE PROBLEM THE DEALER REPLACED MY MASTER CYLINDER AND BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLY. I FOUND THAT THERE IS A RECALL FOR THE 2010 PRIUS. T-CP-DOM DATE OF ISSUE JULY 1, 2013. THE RECALL IS FOR THE SAME PROBLEM I HAD, I DO NOT KNOW WHY I AM BEING EXCLUDED FROM THE RECALL. PLEASE REPLY

MY BRAKES RECENTLY STOPPED WORKING AS THEY NORMALLY DO (YOU HAD TO PRESS EXTREMELY HARD ON THE PEDAL TO GET IT TO STOP) AND SEVERAL LIGHTS CAME ON THE DASHBOARD. PRIOR TO THIS THE CAR WAS MAKING A VERY STRANGE NOISE WHEN YOU START TO PUSH ON THE BRAKES. NOT LIKE A TYPICAL SQUEAKY BRAKE SOUND. I TOOK IT TO TOYOTA AND THEY GAVE ME A QUOTE FOR $3,700 STATING THAT I NEEDED A NEW BRAKE CYLINDER ASSEMBLY. I DISCOVERED A RECALL FOR 2010 PRIUS FOR THE EXACT DIAGNOSTIC CODE AND THEY SAID MY PRIUS WAS NOT COVERED BY THE RECALL. WHEN YOU "REBOOT" THE COMPUTER ON THE PRIUS, THE LIGHTS AND BRAKE PROBLEM GO AWAY. THIS APPEARS TO BE A SIGNIFICANT PROBLEM WITH THE 2010 PRIUS FROM WHAT I HAVE READ ON-LINE AND TOYOTA IS NOT ACKNOWLEDGING IT. IT'S ALSO A VERY COSTLY REPAIR THAT SEEMS TO BE EASILY FIXED WHEN YOU REBOOT THE COMPUTER ON THE CAR. WHAT IS GOING ON? HOW MANY PEOPLE ARE PAYING TOYOTA FOR THIS FIX THAT APPEARS TO BE A WIDE PROBLEM WITH THE VEHICLE THAT SHOULD NOT BE HAPPENING?

I'VE COUNTED AT LEAST 30 BRAKE BOOSTER/ACTUATOR COMPLAINTS ON THIS SITE YEAR TO DATE FOR THE SAME ISSUE ON THIS MODEL YEAR CAR. OUR ISSUE IS THE SAME AS EVERYONE ELSE. JUST UNDER 150K MILES, BRAKE, ABS AND TRACTION CONTROL LIGHTS CAME ON MY DAUGHTER'S CAR (WE ARE ORIGINAL OWNERS) AS SHE WAS DRIVING HOME FROM WORK. NON RESPONSIVE BRAKES, ONLY REAR BRAKES ENGAGE IF YOU PUSH THE PEDAL TO THE FLOOR OF THE CAR. TOOK TO DEALER WHO DIAGNOSED DTC C1391, ACCUMULATOR LEAK MALFUNCTION. OUR CAR WAS NOT INCLUDED IN ORIGINAL WARRANTY ENHANCEMENT (MANUFACTURE DATE OF 1/2010), SO PRICE QUOTED WAS $4814.66. OUR DAUGHTER CANNOT AFFORD, SO WE CALLED TOYOTA WARRANTY WHO OFFERED US $2007 AS A MEASURE OF GOOD WILL, BUT NO MORE. THIS IS A SERIOUS SAFETY ISSUE, BEYOND RIDICULOUS THAT SOME CARS WITH THE SAME DEFECT HAD THE WARRANTY ENHANCEMENT PROGRAM AVAILABLE WHICH PAID FOR THE ENTIRE REPAIR, YET MOST OTHERS LIKE US WERE DENIED THE FIX AND ARE FACING ASTRONOMICAL REPAIR BILLS THAT MANY CANNOT AFFORD, NOR ANTICIPATE ON A CAR SUCH AS A TOYOTA. THE BRAKES FAILED WHILE MY 22 YEAR OLD DAUGHTER WAS DRIVING - THAT COULD HAVE GONE SO VERY WRONG.

COPIED THE BELOW FROM ANOTHER COMPLAINT BECAUSE THIS GUY IS HAVING THE EXACT SAME ISSUE I AM HAVING, I BOUGHT THE CAR AUG 2017 RIGHT BEFORE THE PERIOD TO GET IT REPLACED EXPIRED, WAS NEVER NOTIFIED IN ANY WAY OF THIS WARRANTY CHANGE SO HOW AM I SUPPOSED TO KNOW I HAVE A DEFECTIVE PART ON MY CAR..

THEY ALSO KEEP MENTIONING THE EXTENDED WARRANTY ON THE ACTUATOR IS ONLY FOR "CERTAIN VIN'S". SO THEY ARE GONNA EXTEND THE WARRANTY ON CERTAIN 2010 PRIUS' BUT NOT ALL OF THEM.. THIS MAKES NO SENSE.. PLEASE HELP MY 2010 PRIUS IS HAVING ISSUES AS SAME AS THE SAFETY RECALL BACK IN 2013 ( 13V-235 ). THE ABS LIGHT, VSC LIGHT, AND BRAKE LIGHT WERE ON AFTER A BUMPY ROOAD IN MY NEIGHBORHOOD. I BROUGHT IT TO THE DEALER AND THEY INDICATED THAT THERE WAS A LEAK IN THE ACCUMULATOR. AFTER RESET THE SYSTEM, ALL THE LIGHTS WENT OFF BUT I STILL FEEL THE LOSSES OF PRESSURE ON THE BRAKE PEDAL. HOWEVER, MY CAR HAS 0 OPEN RECALL AND THE DEALER QUOTED ME OVER 5K FOR THE REPAIR WHICH IS RIDICULOUS COMPARE TO THE VALUE OF THE CAR.

MY CAR HAD THE ABS WARNING LIGHT ON AND I HEARD A STRANGE NOISE IN THE ENGINE COMPARTMENT. LAST YEAR. ON OCTOBER 7, 2017, I WAS DRIVING ON THE HIGHWAY AND ANOTHER DRIVER CUT ME OFF, SO I HAD TO BREAK HARD. THE CAR PULLED HARD TO ONE SIDE AND I HIT THE RETAINING WALL. FORTUNATELY, THE DAMAGE TO THE CAR WAS ON THE BUMPER COVER ONLY, AND I WAS NOT INJURED, SO I WAS ABLE TO CONTINUE DRIVING. THE DEALER RAN DIAGNOSTICS ON MY CAR AFTER THE CRASH AND REPORTED I NEEDED TO HAVE CERTAIN PARTS REPLACED. TOYOTA SAFETY RECALL 13V-235 DESCRIBES EXACTLY THE SYMPTOMS MY CAR SHOWS AND REQUIRES REPLACEMENT OF EXACTLY THE SAME PARTS. THE ONLY PROBLEM IS THAT MY CAR'S VIN DOES NOT FALL IN THE RANGE TOYOTA REPORTED IN THE RECALL. APART FROM THAT , THE PROBLEM IS THE SAME. MY ACCIDENT COULD HAVE BEEN VERY SERIOUS HAD THE RETAINING WALL THAT STOPPED ME NOT BEEN THERE. I COULD HAVE BEEN IN THE CENTER LANES AND THE STORY WOULD HAVE BEEN VERY DIFFERENT, EVEN WITH ME SURVIVING THE ACCIDENT.

I NOTICED A 'CLICKING' IN MY BRAKES AND LOSS OF PRESSURE IN NOV. 2017. I TOOK IT TO A MECHANIC FRIEND TO LOOK IT OVER AND I WAS ADVISED THAT IT WAS THE BRAKE BOOSTER LEAKING AND I SHOULD TAKE IT TO THE DEALERSHIP BECAUSE THERE HAD BEEN A 'RECALL' SENT ON CERTAIN VIN #S BUT MINE WASN'T LISTED ON IT. WHEN I TOOK IT TO THE DEALERSHIP THEY WANTED TO CHARGE ME $700+ TO DIAGNOSE AND 'FIX' THE ISSUE. IT WAS NOT ON THE RECALL LIST BECAUSE OF THE PRODUCTION DATE OF MY CAR. I FOUGHT WITH TOYOTA CORP AND THEY DECIDED TO COVER THE COST AS A 'COURTESY'. THE CLICKING STOPPED FOR ABOUT 3 WEEKS THEN CAME BACK MUCH LOUDER AND MORE FREQUENTLY. STILL LOSING PRESSURE, ENOUGH SO THAT WHEN I WAS SITTING AT A STOP LIGHT I WOULD PUT THE CAR IN 'PARK' TO KEEP IT FROM MOVING FORWARD. AGAIN THE DEALERSHIP SAID THIS WAS NOT COVERED BY THE RECALL AND THIS TIME THE COST WOULD BE $4700+ TO 'FIX' THE ISSUE. THIS TIME THEY TOLD ME THEY CONFIRMED THE NITROGEN LEAK WITH THE 'BUBBLE TEST' SO IT WAS, IN FACT, THE BRAKE BOOSTER, BUT IT WAS STILL NOT COVERED. THIS TIME TOYOTA SAID THEY WOULD ONLY PAY $2000 FOR THE TOTAL COST, AGAIN AS A 'COURTESY', BUT I WOULD BE RESPONSIBLE FOR THE REMAINING AMOUNT. I ASKED THE DEALERSHIP IF THERE WAS SOMETHING I HAD DONE TO CAUSE THIS ISSUE AND I WAS TOLD 'NO'. TO ME THEN THAT IS A DEFECT FROM THE MANUFACTURER AND I SHOULD NOT BE RESPONSIBLE. I HAVE MAINTAINED THIS VEHICLE WITH THE DEALERSHIP ON A CONSISTENT BASIS, ALWAYS TAKING IT TO THEM FOR OIL CHANGES, ROTATIONS, ETC. ALWAYS ON THE SUGGESTED TIME SCHEDULE.

ON OCTOBER 7, 2017 A DRIVER CUT ME OFF ON THE HIGHWAY, I PRESSED MY BRAKES HARD AND THE VEHICLE PULLED TO THE SIDE AND I HIT THE RETAINING WALL. THE IMPACT WAS NOT TOO HARD AND I WAS ABLE TO CONTINUE TRAVELLING. THE ABS WARNING LIGHT IS ON AND I HEAR A STRANGE HUMMING NOISE UNDER THE HOOD. THE DEALER RAN DIAGNOSTICS AND SAID I NEEDED TO REPLACE TWO MAIN PARTS IN THE BRAKE SYSTEM. I FOUND A TOYOTA SAFETY RECALL 13V-235 AFFECTING OTHER PRIUS 2010 THAT DESCRIBES EXACTLY THE SAME PROBLEM AND REQUIRES REPLACEMENT OF EXACTLY THE SAME PARTS INDICATED IN THE SAFETY RECALL. THE ONLY PROBLEM IS THAT TOYOTA REPORTED THIS PROBLEM IN VEHICLES OF THE SAME YEAR AND MODEL, BUT MY CAR'S VIN WAS NOT INCLUDED IN THEIR INDICATED RANGE. THANK YOU FOR YOUR HELP

TURNING LEFT AFTER A STOP SIGN ON A SINGLE LANE STREET (30 MPH), SUDDENLY THE DASH BOARD STARTED FLASHING 'STOP CAR' WARNING AND CONTINUES BEEPING. ALSO, REALIZED THAT APPLYING BREAK PADDLE DID NOT HELP A BIT. IT WAS HARD TO PRESS THE PADDLE THAT MOVED A LITTLE BIT. GOING STRAIGHT ABOUT 300 FT. CAR REDUCED TO IDLING SPEED. TURNING LEFT INTO A PARKING LOT OF A SCHOOL, I TRIED STOPPING IT INTO A PARKING SPACE. BREAK DID NOT WORK AGAIN. SO, CAR STOPPED AFTER HITTING THE CURB. TOYOTA DEALERSHIP WAS CALLED AND ARRANGEMENTS WERE MADE TO TOW AWAY CAR FROM SCHOOL'S PARKING LOT. THE CAR DID NOT STOP WHEN TOWING PERSON TRIED TO REVERSE DRIVE. SOMEHOW HE MANAGED TO MANEUVER IT ON A TOW TRUCK. I WAS INFORMED BY DEALERSHIP THAT BREAK ASSIST SYSTEM (BAS), BUILT INTO PRIUS HYBRID MODEL, FAILED. THE SYSTEM COMPRISES OF ACCUMULATOR & PUMP THAT ASSISTS TO STOP THE CAR WHEN BREAK PADDLE IS PRESSED. THOUGH CAR WAS COVERED UNDER WARRANTY, BREAK SYSTEM AND ASSOCIATED COMPONENTS WERE NOT COVERED. REPAIR COST OVER $1900 TO REPLACE BAS. PURPOSE OF THIS COMPLAINT TO HIGHLIGHT NHTSA OF THE CRITICAL FAILURE OF PRIUS DESIGN TO ALLOW BREAK SYSTEM TO FAIL IN SUCH A COLOSSAL WAY. THE CAR COULD NOT BE STOPPED. THIS IS A SERIOUS DRIVING SAFETY CONCERN. ANY FAILURE OF BREAK ASSIST COMPONENT SHOULD NEVER EVER TAKE AWAY THIS CRITICAL CONTROL. INTENT OF THIS COMPLAINT IS FOR THE PUBLIC SAFETY, HAVING TOYOTA INFORMED OF THE INCIDENT. IT HAS BEEN VERY DISAPPOINTING THAT TOYOTA HAS NOT GIVEN ANY RESPONSE EXCEPT GIVING A CASE NUMBER BY A CUSTOMER SERVICE CENTER. REQUEST NHTSA TO LOOK INTO THE INCIDENT AND MOST IMPORTANTLY REVIEW DESIGN OF BREAK ASSIST SYSTEM FOR PRIUS IN THE INTEREST OF PUBLIC SAFETY AND DEFENSIVE DRIVING. PLEASE ADVISE SHOULD NHTSA REQUIRE FURTHER DETAILS OR INCIDENT NARRATIVE.

APPROACHING A STOP THE BRAKE PEDAL IN THE PRIUS WILL SUDDENLY LOSE RESISTANCE AND WILL NEED TO BE PUSHED TO THE FLOOR WHERE THE BRAKES WILL FINALLY ENGAGE AND THE AUTO WILL COME TO A HARD STOP. THIS HAPPENS RANDOMLY AND IS DIFFICULT FOR A MECHANIC TO DUPLICATE. I TOOK THE VEHICLE TO A TRUSTED MECHANIC (NOT THE TOYOTA DEALERSHIP) AND HE CONFIRMED IT IS AN HYDRAULIC PROBLEM AND THAT PADS/DRUMS/ETC. ARE OK. A RECALL WAS ISSUED FOR 2010 PRIUS'S DESCRIBING THIS EXACT SITUATION BUT MY VIN NUMBER WAS NOT INCLUDED IN THIS RECALL. RECALL DETAILS THE BRAKE BOOSTER PUMP CONTAINS A COMPARTMENT FILLED WITH NITROGEN GAS. THIS NITROGEN GAS CAN LEAK INTO THE BRAKE FLUID CAUSING REDUCED HYDRAULIC PRESSURE DURING APPLICATION OF THE BRAKES. REDUCED BRAKING EFFICIENCY CAN INCREASE THE RISK OF A CRASH. DEALERS WILL REPLACE THE BRAKE BOOSTER PUMP ASSEMBLY AS NECESSARY TO CORRECT THIS CONCERN. OUR QUICK TAKE REDUCED BRAKING PERFORMANCE MAY BE EXPERIENCED DUE TO A BRAKE BOOSTER SYSTEM ISSUE. WHAT SHOULD YOU DO? TOYOTA WILL BEGIN NOTIFYING OWNERS OF THE AFFECTED VEHICLES DURING JULY, 2013. IF YOU NOTICE PROBLEMS WITH THE BRAKING SYSTEM, OR YOU DON'T RECEIVE NOTIFICATION AND YOU FEEL YOU SHOULD HAVE, PLEASE CONTACT YOUR DEALER FOR FURTHER INSTRUCTION. THEY MAY ASK FOR YOUR VEHICLE IDENTIFICATION NUMBER (VIN), SO PLEASE HAVE IT HANDY WHEN YOU CALL. ON JAN 16, 2018 I CALLED MY LOCAL TOYOTA SERVICE DEPARTMENT AND WAS TOLD NOTHING COULD BE DONE AS I HAVE NO OUTSTANDING RECALLS ON THE VEHICLE. I THEN CALLED TOYOTA ON JAN 17 AND THEY TOLD ME MUCH THE SAME AND OPENED A CASE NUMBER FOR THE ISSUE. THIS ISSUE SEEMS TO BE COVERED ON NHTSA NUMBER 13V235000. I AM REQUESTING NHTSA ADVICE AS TO HOW TO PROCEED.

BRAKE LIGHTS CAME ON WHILE DRIVING ON FREEWAY. POWER BRAKES SEEMED TO FAIL AND A LARGE AMOUNT OF PRESSURE WAS REQUIRED TO STOP VEHICLE. TOYOTA OF FORT WORTH DEALERSHIP DIAGNOSED THAT THE ACTUATOR NEEDED TO BE REPLACED. WE PERFORMED REPAIR (AT A COST OF ROUGHLY $2,000.) A FEW DAYS LATER ON A LONGER DRIVE THE BRAKE LIGHTS TURNED BACK ON. WE RETURNED IT TO THE DEALERSHIP AND WERE TOLD THAT THE BRAKE BOOSTER/MASTER CYLINDER ASSEMBLY NEEDED TO BE REPLACED AT AN ADDITIONAL COST OF $2,900. I NOTICE THAT TOYOTA HAD A RECALL FOR THIS PART ON OTHER 2010 PRIUS VEHICLES BUT MY VEHICLE IS NOT INCLUDED IN THAT RECALL.

REFERENCE: TOYOTA PRIUS BRAKE BOOSTER PUMP ASSEMBLY RECALL 2013 THE 2013 RECALL WAS ISSUED FOR APPROXIMATELY 82,000 PRIUS VEHICLES MANUFACTURED FROM MARCH 2009 TO OCTOBER 2009. THE CAR I OWN AND OPERATE, ACCORDING TO A TOYOTA REPRESENTATIVE, WAS BUILT IN DECEMBER 2009 -- THUS, I PRESUME, DID NOT FIT WITHIN PARAMETERS OF THIS PARTICULAR RECALL. A TOYOTA CUSTOMER SERVICE REPRESENTATIVE SAID THAT THE VEHICLE MATCHING MY VIN NUMBER HAS NO SAFETY RECALLS ASSOCIATED WITH IT. HOWEVER, THE SAME ISSUE REFERENCED IN THE RECALL -- A FAULTY BRAKE PRESSURE ACCUMULATOR THAT COMPROMISES THE BRAKE BOOSTER PUMP ASSEMBLY SYSTEM -- APPEARS TO HAVE SURFACED IN MY 2010 PRIUS. NO ACCIDENT HAS OCCURRED. THE VEHICLE IS INDICATING A PROBLEM VIA ITS DASHBOARD WARNING LIGHTS. A TOYOTA MAINTENANCE TECHNICIAN, ON SEPT 21, 2017, DIAGNOSED THAT THE CAR'S BRAKE ACCUMULATOR PUMP IS MALFUNCTIONING -- AND THAT IT NEEDED TO BE REPLACED. I AM PETITIONING FOR CONSIDERATION TO EXPAND THE 2013 RECALL, WHICH WAS ORDERED TO CORRECT A DESIGN/MANUFACTURING DEFECT. THE SAME FLAW IS PRESENT IN MY VEHICLE (EVEN THOUGH MY VEHICLE WAS NOT COVERED BY THE ORIGINAL RECALL).

MY 2010 PRIUS HAS HAD LIGHTS COME UP ON THE DASHBOARD. VSC, BRAKE, TRACTION & ABS. AFTER THE LOCAL TOYOTA DEALERSHIP RAN DIAGNOSTICS, IT CAME TO LIGHT THAT THE BRAKE ASSEMBLY WITH ACCUMULATOR WILL NEED TO BE REPLACED FOR NEAR $5,000. IT WOULD SEEM THAT THIS IS A COMMON PROBLEM THAT HAS RESULTED IN A RECALL FOR ONLY SOME OF THE 2010 PRIUS MODELS. MINE WAS NOT ONE OF THESE RECALLED. I WOULD LIKE TO REQUEST RECOGNITION THAT THIS SHOULD BE COVERED UNDER THE SAME RECALL. TOYOTA IS A GOOD PRODUCT, AND I UNDERSTAND THAT RECALLS ARE JUST A PART OF LIFE. AS IT STANDS, MY REGENERATIVE BRAKING NO LONGER WORKS AND I HAVE BEEN INFORMED THAT I WILL LOSE ALL BRAKING EVENTUALLY.

I WAS DRIVING TO MY HOUSE AND THE BRAKE PEDAL WENT TO THE BOTTOM. SEVERAL LIGHTS APPEARED ON THE DASHBOARD. I WAS DRIVING IN THE HIGHWAY AND FORTUNATELY THERE WAS AN EXIT AND I COULD GET OUT OF THE HIGHWAY AND I MANAGE HOW TO STOP AND I DID NOT CRASH. THE STORY COULD BE ANOTHER IF I WAS DRIVING FASTER. THE NEXT DAY I TOOK IT TO THE TOYOTA DEALER AND THEY TOLD ME THAT THE PROBLEM WAS THE BOOSTER PUMP (ATTACHED YOU CAN FIND THE ESTIMATE). I WAS SHOCKED WHEN I FOUND HOW MUCH WAS GOING TO COST ME. MY CAR HAS NEVER HAD A PROBLEM AND ALL OIL CHANGES HAD BEEN AT THE SAME TOYOTA DEALER. I HAVE NEVER TAKEN THE CAR ANYWHERE ELSE. INVESTIGATING I FOUND THAT THIS MODEL PRIUS 2010 IN 2013 HAD A RECALL FOR THIS SAME PROBLEM AFFECTING 82000 PEOPLE. UNFORTUNATELY, THE VIN NUMBER OF MY VEHICLE IS NOT IN THIS RANGE THAT REACHES A0067875 AND MINE IS A0205005. I NEED FOR TOYOTA TO EXTEND THE RECALL RANGE BECAUSE THE PROBLEM IS EXACTLY THE SAME AND ALSO HELP ME TO COVER THE COST OF THE REPAIR. AT THIS MOMENT, MY CAR IS PARKED AT HOME BECAUSE IS NOT DRIVABLE. I ALREADY SPOKE WITH TOYOTA HEADQUARTERS AND THEY SAID THAT THEY WILL NOT HELP ME WITH THE COST OF THE REPAIR, IT IS REALLY EXPENSIVE AND IT IS NOT MY FAULT. DOES TOYOTA HAVE TO WAIT UNTIL THERE IS AN ACCIDENT? OR INJURY OR DEAD PEOPLE?

I TOOK MY 2010 PRIUS IN FOR AIRBAG WORK & THEY ASKED HOW LONG I HAD BEEN DRIVING W/ MY BRAKE WARNING LIGHTS ON. THEY HAD NOT BEEN ON PRIOR TO THEN. THEY HOOKED UP A COMPUTER & SHOWED ME THAT THE VEHICLE HAD BEEN STARTED 31 TIMES SINCE THE WARNING WAS 1ST DETECTED. THEY SAID THERE WAS MOST LIKELY A LEAK IN THE BRAKE BOOSTER SYSTEM. THEY RESET THE WARNING, I DROVE FOR A DAY & IT CAME BACK ON AGAIN WHILE DRIVING AFTER ABOUT 10 STARTS. AFTER THE WARNING LIGHTS CAME ON AGAIN, I NOTED AN IMMEDIATE & SIGNIFICANT CHANGE IN BRAKING RESPONSIVENESS & VEHICLE CONTROL...STARTED PULLING TO THE RIGHT. THIS WAS ON THE HIGHWAY WHILE DRIVING STRAIGHT. I TOOK THE CAR IN TO A LOCAL TOYOTA DEALER FOR FULL DIAGNOSTIC & THEY SAID THAT THEY'RE WERE UNABLE TO LOCATE THE EXACT LEAK LOCATION, BUT THAT THEIR TECH ORDER SHOWS TO JUST REPLACE THE BOOSTER WHICH WILL COST ABOUT $3,300 O REPLACE.

ALSO DISCOVERED THAT TOYOTA ISSUED AN "ENHANCED WARRANTY PROGRAM (ZG1) FOR MODELS 2004-2009. BUT MY NEWER MODEL (2010) IS NOT INCLUDED IN THE ENHANCED WARRANTY PROGRAM.

WHICH WOULD COST ME 2,000 DOLLARS PARTS AND LABOR. THEY ALSO TOLD ME THEY MIGHT FIND OUT THAT THE MASTER CYLINDER MIGHT HAVE TO BE REPLACED AS WELL IF DAMAGED. WHICH WOULD BE 3,300 DOLLARS. SO WORST CASE SCENARIO IT WOULD BE OVER 5,000 WITH TAX TO FIX MY CAR. I NOTICED OTHER 2010 PRIUS MODELS WERE RECALLED FOR THE EXACT ISSUE BUT ONLY CERTAIN VIN NUMBERS. MY VIN NUMBER WASN'T INCLUDED.

I AM THE ORIGINAL OWNER OF A 2010 PRIUS. WITHIN THE FIRST MONTH, I CONTACTED TOYOTA, COMPLAINING OF THE BRAKES, WHICH WERE NOT CONSISTENTLY SMOOTH. IN GENERAL, THE BRAKES WORK FINE, BUT IF I HIT A BUMP OR DITCH, THE BRAKES SUDDENLY STOP WORKING FOR A SPLIT SECOND, AND THE CAR FEELS LIKE IT IS LURCHING FORWARD, BEFORE THE BRAKES SUDDENLY START WORKING AGAIN. TOYOTA SERVICE WAS NEVER ABLE TO "REPRODUCE" THE PROBLEM, AND EVENTUALLY I GAVE UP. A COUPLE YEARS AGO, THE CAR WAS RECALLED FOR THIS PROBLEM, AND I BROUGHT THE CAR IN TO BE FIXED. UNFORTUNATELY, THE RECALL WORK HAS NOT REMEDIED THE PROBLEM. THE BRAKES STILL SEEM TO OCCASIONALLY MALFUNCTION WHEN THE CAR DRIVES OVER A ROUGH PATCH. TOYOTA SEEMS TO BELIEVE THE PROBLEM HAS BEEN SOLVED, BUT IT HAS NOT BE SOLVED. THERE IS NO DIFFERENCE SINCE THE RECALL.

THIS AFTERNOON, MY WIFE WAS DRIVING DOWN A TWO LANE, PAVED STREET AT ABOUT 25 MPH. THE STREET HAS A SLIGHT DECLINE AND SHE BEGAN TO APPLY THE BREAKS TO SLOW DOWN SLIGHTLY. JUST A SECOND OR TWO LATER, SHE HIT A SMALL BUMP IN THE ROAD AND THE CAR ACCELERATED (WHILE SHE HAD HER FOOT ON THE BREAK) FOR A FRACTION OF A SECOND. WE DIDN'T HEAR THE SOUND OF THE ENGINE REVVING. THANKFULLY, THERE WERE NO OTHER CARS ON THE ROAD AT THIS TIME AND THERE WAS TIME TO PRESS THE BREAK AGAIN. BASED ON LOOKING AROUND ONLINE, MANY PEOPLE HAVE REPORTED SIMILAR ISSUES (HTTP://WWW.CONSUMERREPORTS.ORG/CRO/NEWS/2010/02/TOYOTA-ADDS-2010-PRIUS-BRAKING-PROBLEM-TO-THE-LIST-RECALL-POSSIBLE/INDEX.HTM).

RELEASING THE BRAKE AND ATTEMPTING AGAIN SEEMS TO BE A SOLUTION, BUT I OFTEN DON'T HAVE TIME BEFORE REACHING THE INTERSECTION I'M APPROACHING. THIS CONSISTENTLY HAPPENS IN TWO PLACES IN MY DAILY COMMUTE WITH A SLIGHT BUCKLE IN THE ROAD APPROACHING AN INTERSECTION ON CITY STREETS AND COUNTY ROADS.

DRIVING DOWN HIGHWAY AT POSTED SPEED LIMIT (75MPH), I TRIED TO SLOW DOWN DUE TO TRAFFIC AND NOTICED MY CARS ABILITY TO BRAKE WAS SEVERELY COMPROMISED. I THEN NOTICED MY CARS BRAKES, ABS, MASTER WARNING AND VSC LIGHTS HAD CAME ON. GIVEN THAT MY CAR HAS 103K MILES ON IT, I FIGURED IT IS TIME FOR A BRAKE PAD SERVICE. WITH THE LIMITED BRAKING ABILITY, I DECIDED TO MAKE THE SHORT DRIVE TO THE TOYOTA DEALER FOR BRAKE SERVICE. AFTER THE DEALER INSPECTED MY CAR, A REPRESENTATIVE TOLD ME THAT IT IS NOT THE BRAKE PADS THAT ARE CAUSING THE LIGHTS IN YOUR DASH TO GO ON BUT RATHER THE BRAKE BOOSTER. THEY ADVISED ME THAT IT IS NOT RECOMMENDED THAT I DRIVE THE CAR ANYMORE UNTIL THE ISSUE IS REMEDIED BY REPLACING THE BRAKE BOOSTER AT A COST OF OVER 2K. I HAD TO ALSO INCUR THE COST OF A RENTAL SINCE THE BOOSTER WAS NOT IN STOCK AND WOULD TAKE OVER THE WEEKEND TO RECEIVE. I WAS TAKEN ABACK BY THE TOTAL COST OF THE SERVICE BUT HAD NO CHOICE AND PROCEED TO GET IT REPAIRED. UPON RECEIVING MY CAR A FEW DAYS LATER, I DROVE TO WORK AND UPON MY RETURN HOME, THE ISSUE REPEATED ITSELF WITH ALL THE LIGHTS ON THE DASH LIGHTING UP AND THE CARS BRAKING ABILITY WAS AGAIN COMPROMISED. EXTREMELY IRATE, I DROVE DIRECTLY TO THE DEALER AND UPON INSPECTING THE CAR THEY TOLD ME THAT IT IS NOW THE ACCUMULATOR THAT NEEDS TO BE REPLACED. THIS TIME THE DEALER ABSORBED THE COST OF OVER 3K TO REPLACE IT. I RESEARCHED THE INTERNET FOR ANY KNOWN RECALLS AND FOUND THE ISSUE WAS BEING ADDRESSED BY TOYOTA WITH A RECALL HOWEVER MY CARS VIN WAS NOT PART OF IT. IT IS MY HOPES THAT YOU MAKE TOYOTA AWARE OF THE SAFETY ISSUE AND INITIATE A RECALL ON ALL 2010 PRIUS MODELS AND NOT JUST SOME. I WOULD ALSO LIKE TO GET THE COST I INCURRED WITH THIS SAFETY ISSUE REIMBURSED AT SOME POINT.

ABS ACTUATOR WITH MASTER CYLINDER ASSEMBLY HAS INTERNAL LEAK. ASSEMBLY DOESN'T HOLD PRESSURE AND ACTUATOR MOTOR CONTINIOUSLY WORKING IN ORDER TO CREATE THE PRESSURE. DUE TO THIS PROBLEM BRAKES ARE NOT OPERATE AS PROPERLY. IT TAKES MORE STRENGTH TO PUT ON THE PEDAL TO STOP VEHICLE. I ALSO NOTICED THAT DURING EMERGENCY BRAKING NOT ALL WHEELS WERE INVOLVED EQUALLY. DUE TO THIS PROBLEM BRAKING DISTANCE SIGNIFICANTLY INCREASED. I HAVE 3 INSTRUMENT CLUSTER ERROR LIGHTS TURNED ON DUE TO THIS PROBLEM: "BRAKE", LIGHT WITH VEHICLE ON SLEEPY ROAD, AND LIGHT WITH "!" SIGN. I FOUND THAT THERE ALREADY WAS RECALL FOR SAME 2010 YEAR TOYOTA PRIUS UNDER TMS-NTC-13178 OF JULY 23, 2013, TOYOTA RECALL NAME D0H, BUT MY VEHICLE IS NOT COVERED.

THE BRAKE ACTUATOR FAILED ON OUR 2010 PRIUS III MANUFACTURED IN OCTOBER 2010. TOYOTA IS COVERING PROBLEMS WITH THIS SAME BRAKE ACTUATOR FOR 2010 PRIUS MANUFACTURED BETWEEN MARCH 2009 AND EARLY OCTOBER 2009. MY VIN DID NOT FALL INTO THAT DATE RANGE EVEN THOUGH MINE WAS MANUFACTURED IN OCTOBER 2009, SO THE BRAKE DEFECT SHOULD BE EXTENDED TO BEYOND THE EARLY OCTOBER 2009 MANUFACTURED DATE.

I HAVE A 2010 TOYOTA PRIUS. WHEN TRYING TO SLOW DOWN, ANY TIME A BUMP IS HIT, (OR A POTHOLE) THE BRAKING POWER SIGNIFICANT DECREASES . THIS GREATLY INCREASES THE STOPPING DISTANCE AND IS VERY SCARY IN TRAFFIC AND IN WINTER DRIVING. IS THIS A PROBLEM? I CALLED TOYOTA EARLIER FOR THE SAME ISSUE AND THEY TOLD ME THAT THIS IS NORMAL AND THIS OCCURS BECAUSE ONLY ONE TIRE IS HITTING THE POTHOLE OR BUMP' IT IS VERY SCARY AND I HAVE TO LEAVE A LOT OF SPACE AHEAD OF MY CAR.

I RECENTLY PURCHASED A TOYOTA 2010 PRIUS AND FOUR DASH WARNING LIGHTS APPEARED THE DAY AFTER I PURCHASED IT WHEN I TURNED THE CAR ON IN THE MORNING. THE LIGHTS STAY ON FOR HOURS TO DAYS AND GO OFF FOR SIMILAR AMOUNT OF TIME. WHEN THE LIGHTS ARE ON THE BRAKES ARE MUCH LESS RESPONSIVE AND THE BRAKING ACTION DOES NOT CHARGE THE BATTERIES AS MUCH, NEVER MORE THAN 25% OF CHARGING POTENTIAL. THE PROBLEM WAS DIAGNOSED AS A PROBLEM WITH ACCUMULATOR IN THE BRAKE SYSTEM.

HELLO. I RECENTLY STARTED TO EXPERIENCE AN ISSUE WITH MY VEHICLE. MY BRAKES STARTED TO MAKE SOME KIND OF UNUSUAL NOISES EVERY TIME I PRESS ON THEM. I'VE NEVER HAD THAT BEFORE AND I SERVICE MY CAR PRETTY OFTEN. I WENT TO AUTHORIZED TOYOTA DEALERSHIP AND THEY TOLD ME THERE WAS A COMPUTER ISSUE AND THEY FIXED IT FOR $110. IT CONTINUED TO MAKE NOISES AND ALL OF THE SUDDEN IT BEGAN SHOWING ABS/BRAKE/VSC LIGHTS ON MY CAR DASHBOARD EITHER WHILE I WAS DRIVING OR BEING IN THE 'PARK' MODE. AT THE SAME TIME MY BRAKES STOPPED WORKING WELL WHILE DRIVING WHEN THE ABS/BRAKE/VSC LIGHTS WERE ON. I CHECKED THE CODE OF THE ERROR THROUGH THE CAR COMPUTER AND IT SHOWED ME 'C1391'. I WENT TO THE DEALERSHIP AGAIN AND THEY DID ANOTHER CHECK AND THIS TIME THEY FOUND THAT BRAKE MASTER CYLINDER/BOOSTER/ABS ASSEMBLY NEEDS TO BE REPLACED WITH $3,170 PRICE. I ATTACHED HERE THE PAPER THAT MY TOYOTA PRIME DEALERSHIP LOCATED HERE IN SACO, ME GAVE ME. I'VE BEEN READING A LOT ABOUT IT ONLINE AND PEOPLE WITH THE SAME TYPE OF HYBRID VEHICLES HAVE EXPERIENCED IT. I THINK TOYOTA NEEDS TO LOOK INTO THE ISSUE AND ACKNOWLEDGE THAT IT IS A COMMON PROBLEM IN THEIR HYBRID VEHICLES. I SERVICE MY CAR ALL THE TIME, I DO OIL CHANGE AND CHECK ALL THE SYSTEMS VERY THOROUGHLY, SO I DON'T UNDERSTAND WHY WE, CONSUMERS, HAVE TO PAY THAT BIG OF A PRICE FOR THE CAR REPAIR. I HOPE YOU CAN LOOK INTO THE ISSUE AND HELP ME (AND TO ALL OTHER CAR OWNERS) TO RESOLVE THIS KIND OF ISSUE. THANK YOU.

I WENT TO START THE PRIUS AFTER WORK, AFTER I PRESSED THE START BUTTON, SEVERAL ALARMS WENT OFF ON THE MAIN PANEL. ALARMS INCLUDED THE MASTER ALARM, ABS, BRAKE, CHECK ENGINE, AND AN INCESSANT BEEPING. THERE WAS ALSO A REPETITIVE SOUND COMING FROM UNDER THE HOOD THAT SOUNDED LIKE THE BRAKING SYSTEM WAS TRYING TO BUILD PRESSURE, BUT WAS NOT SUCCESSFUL. I TOWED THE VEHICLE TO THE DEALERSHIP AND THEY DIAGNOSED THIS AS THE MASTER BRAKE BOOSTER ASSEMBLY. THE QUOTE WAS $2500 FOR THE PART, AND $500 IN LABOR. THEY STARTED WORK ON THE VEHICLE, THEN CALLED AND SAID THAT THEY WOULD HAVE TO REPLACE THE ACCUMULATOR AS WELL, EVEN THOUGH IT WAS ALREADY REPLACED DURING THE ORIGINAL RECALL. THEY CONTACTED TOYOTA CORPORATE WHO PAID FOR THE ACCUMULATOR, BUT WOULD NOT COVER THE ADDITIONAL LABOR TO INSTALL THE ACCUMULATOR. THE TOTAL BILL WAS $3900.

INCIDENTALLY, BRAKE FLUID WAS FLUSHED AND CHANGED AT 60,000 AND THEN AGAIN AT 75,000. THE REASON, STATED FROM THE DEALER IS THAT MAINTENANCE WAS RESPONSIBLE FOR THE FAILURE.

I AM EXPERIENCING A RESURGENCE OF THE ACCELERATION WHILE BRAKING PHENOMENON THAT WAS THE BASIS OF THE 2010 RECALL. WE HAD THE CAR FIXED AT THE TIME OF THE RECALL. THE INCIDENTS RELATE TO WHEN I AM BRAKING AND HAPPEN TO GO OVER A BUMP OR HIT A POTHOLE. AS I AM BREAKING THE CAR SUDDENLY ACCELERATES FORWARD AND YOU HAVE TO KEEP BREAKING HARDER TO KEEP FROM HAVING THE CAR GET AWAY FROM YOU. IT IS NOW HAPPENING ALMOST CONSISTENTLY. AFTER CALLING THE LOCAL TOYOTA DEALER AND THE GENERAL TOYOTA NUMBER, I FIND OUT THAT THEY ARE NOT WILLING TO APPLY THE SAME FIX AS THEY DID IN 2010. I AM NOW FORCED TO TAKE THE CAR IN AND HAVE IT DIAGNOSED AND DON'T KNOW WHAT THEY WILL CHARGE ME FOR THAT. THEN TOYOTA SAID I COULD CALL THEM BACK TO SEE IF THERE IS ANYTHING THEY CAN DO I DON'T UNDERSTAND WHY THEY DON'T HAVE TO STAND BY A FIX THAT IS NOT RELATED TO WEAR AND TEAR BUT RATHER A MALFUNCTION IN THE WAY THEY BUILT THE CAR. IT SHOULD NEVER BE RIGHT TO HAVE A CAR ACCELERATE IF ONE IS BRAKING. THE ONLY DAMAGE TO DATE HAS BEEN A GLARE FROM A CONSTRUCTION WORKER WHO WAS TELLING ME TO STOP ONLY TO SEE THE CAR LURCH TOWARD HIM.

IT WAS TOTALLY UNEXPECTED AND EXTREMELY SCARY. IN HINDSIGHT, I SHOULD HAVE SUSPECTED THAT THERE MAY BE A PROBLEM WHEN I NOTICED THAT SOMETIMES WHEN APPLYING THE BRAKES TO COME TO A STOP THERE WOULD BE A FEELING OF THE BRAKES SLIPPING AND THE CAR LURCHING FORWARD A BIT.

I TAKE IT TO THE TOYOTA DEALER WHO CHARGES ME $111 TO TELL ME I HAVE A BRAKE PROBLEM AND THAT IT WILL COST $4418 TO FIX IT. CODE # C1391; THEY RECOMMEND REPLACING THE MASTER CYLINDER; AND BOOSTER PUMP ASSEMBLY SAYING THERE IS AN ABNORMAL LEAK DOWN OF THE BRAKE ACCUMULATOR. THIS IS INSANE. I CANNOT AFFORD TO FIX IT AND MUST CONTINUE TO WORK TO LIVE; THEREFORE DRIVING ABOUT 200 MILES/DAY WITH HYDRAULIC ONLY BRAKES. MY RESEARCH INDICATES THERE WAS A MAJOR RECALL FOR THIS EXACT PROBLEM ON THE 2010 MODEL. THE DEALERSHIP AND TOYOTA CORPORATE BOTH SAY MY VEHICLE WAS NOT PART OF THE RECALL. I FEEL AS THOUGH IT SHOULD BE SINCE, OBVIOUSLY, THE PROBLEM HAS NOT BEEN SOLVED. I AM NOT ALONE, AS MANY OWNERS ON PRIUSCHAT HAVE THE SAME PROBLEM. THIS IS A MAJOR SAFETY CONCERN TO NOT ONLY MYSELF, OTHER VEHICLES OR PEDESTRIANS, BUT ALSO MY PASSENGERS. AN EXPANDED RECALL IS NECESSARY AND WARRANTED.

DESIGN FLAW....LOSS OF BRAKE FUNCTION DURING BRAKING EVENTS WHILE GOING OVER BUMPS AND POTHOLES (LOWER SPEEDS <30MPH).

ON SEVERAL OCCASIONS, MY CAR HAS GONE THROUGH OR PARTIALLY THROUGH THE INTERSECTION. RECENTLY THIS CAUSED ME TO RUN A RED LIGHT. THIS HAS BEEN GOING ON SINCE I PURCHASED THE CAR USED . I TOOK IT TO THE DEALER (BURIEN AUTO, BURIEN, WA) ABOUT 18 MONTHS AGO WITH A NOTE EXPLAINING WHAT IS HAPPENING, AND THE MECHANIC SAID HE ROAD TESTED IT AND THERE WAS NO PROBLEM.

DRIVER MADE A SUDDEN STOP TO AVOID AN ACCIDENT ON 2/16/15, ENGAGING THE BRAKES. AFTERWARD THE BRAKES ALTERNATED BETWEEN BEING HARD TO PUSH AND BEING SOFT TO PUSH. DRIVER PARKED THE VEHICLE 5 MINUTES LATER. THE NEXT TIME THE CAR WAS TURNED ON(APPROXIMATELY 60M LATER), THE CAR BEGAN BEEPING AND SHOWING THREE ERROR LIGHTS - ABS, (!), AND THE TRACTION CONTROL SYMBOL. AFTER RUNNING DIAGNOSTICS, THE DRIVER WAS TOLD BY A MECHANIC THAT THE PROBLEM SOUNDED EXACTLY LIKE A PREVIOUSLY ISSUED RECALL (TCP-D0H); HOWEVER, TOYOTA HAS INDICATED THAT OUR MODEL IS OUTSIDE THE SCOPE OF THEIR RECALL. GIVEN THAT WE HAVE THE SAME MAKE/MODEL/YEAR CAR AS THE RECALL AND THE SAME ISSUE DESCRIBED, THE SITUATION IS HIGHLY SUSPECT. IN ADDITION TO INSURING MY OWN FAMILY'S SAFETY, I'M HOPING TO MAKE SURE THIS POTENTIALLY DANGEROUS BRAKE ISSUE ISN'T MORE WIDESPREAD THAN TOYOTA HAS ADMITTED.

DRIVING ON HIGHWAY THE ABS AND BRAKE WARNING LIGHTS CAME ON AND AN ALARM STARTED SOUNDING. I WAITED UNTIL LIGHT TRAFFIC APPLIED BRAKES PEDAL FELT LIKE I WAS PRESSING ON A BRICK, NO BRAKING OCCURRED I PRESSED HARDER, THE BRAKES BECAME SOFTER WENT TO THE FLOOR AND THE BRAKE PADS GRABBED HARD ON THE WHEELS. THERE IS NO CONTROLLED BRAKING ON THE CAR. DEALERSHIP SAYS THE BRAKE BOOSTER PUMP FAILED, THIS IS THE SAME YEAR MODEL THAT HAD BRAKING PROBLEMS RELATED TO NITROGEN IN THE BREAK LINES CAUSED BY A FAILED BRAKE BOOSTER PUMP. THE VIN IS ALSO VERY CLOSE TO AFFECTED VEHICLES. FORTUNATELY WHEN THIS OCCURRED I WAS IN A POSITION TO NAVIGATE TO WHERE I COULD TEST THE BRAKES IN A FAIRLY CONTROLLED ENVIRONMENT. HAD IT HAPPENED IN HEAVY TRAFFIC IT WOULD HAVE ALMOST CERTAINLY RESULTED IN A SERIOUS ACCIDENT.

Mileage: 120,000

AS I WAS DRIVING, I NOTICED THAT WHEN I PRESSED ON THE BRAKES, THE CAR WOULD JERK FORWARD BEFORE COMING TO A STOP. ONCE STOPPED (BUT STILL TURNED ON), THE CAR MADE A BUZZING NOISE I HAD NEVER HEARD BEFORE. NO WARNING LIGHTS CAME ON, AND THE BRAKES DID NOT SQUEAK. AN HOUR LATER, MY HUSBAND DROVE THE CAR HOME FOR ME (I RODE WITH A FRIEND), AND HE REPORTED THAT WARNING LIGHTS CAME ON AND THE BRAKES DID NOT WORK PROPERLY. IN ORDER FOR THE BRAKES TO WORK, HE HAD TO PRESS VERY HARD ON THEM AND ALSO ALLOW MUCH MORE DISTANCE FOR THE CAR TO STOP. HE COULD HAVE EASILY CRASHED INTO THE BACK OF ANOTHER VEHICLE. HE TOOK THE CAR TO THE TOYOTA DEALERSHIP AND WAS INFORMED THE BRAKE BOOSTER ASSEMBLY WOULD HAVE TO BE REPLACED. THIS IS THE SAME COMPLAINT AS A 2010 PRIUS RECALL, BUT MY VIN NUMBER WAS NOT INCLUDED IN THE RECALL, SO I DID NOT RECEIVE A NOTICE IN THE AIL. ALSO, WE HAD TO PAY $3008 TO HAVE THE BRAKE BOOSTER ASSEMBLY REPLACED. THE CONSUMER REFERENCED RECALL # 13V235000. UPDATED 02/11/16. *JB

VEHICLES BRAKES ARE SPONGY AND UNPREDICTABLE. THE DEALER RECOMMENDED TO DO A BRAKE FLUID EXCHANGE AND NOW THE PROBLEM HAS GONE AWAY. THIS ISSUE SEEMS VERY SIMILAR TO NHTSA CAMPAIGN ID NUMBER: 13V235000, WHERE NITROGEN ENTERS THE BRAKE FLUID AND MAKES THE BRAKES LESS RESPONSIVE. HOWEVER, THE DEALER SAID THIS VEHICLE IS NOT COVERED BY THAT RECALL AND I WAS CHARGED $150 FOR THE REPAIR.....UPDATED 12/02/15 *BF THE CONSUMER STATED THE BRAKES FELT SPONGY AND WERE UNPREDICTABLE AT LOW SPEEDS OF LESS THAN 20 MPH.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE ATTEMPTING TO PARK THE VEHICLE WITH THE BRAKE PEDAL ENGAGED, THE VEHICLE ACCELERATED INDEPENDENTLY WITHOUT WARNING. AS A RESULT, THE CONTACT CRASHED INTO THE CURB. THE AIR BAGS FAILED TO DEPLOY. A POLICE REPORT WAS NOT FILED AND NO INJURIES WERE REPORTED. THE VEHICLE WAS TAKEN TO A DEALER, BUT WAS NOT DIAGNOSED. THE BODY DAMAGE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 72,000.

WHILE DECELERATING DUE TO APPLICATION OF THE BRAKE PEDAL IF THE VEHICLE ENCOUNTERS A POTHOLE OR OTHER DEEP ROAD IMPERFECTION THE BRAKING CUTS OUT AND THE VEHICLE RESUMES COASTING IMMEDIATELY EVEN THOUGH THE BRAKE PEDAL IS DEPRESSED. HARDER APPLICATION OF THE BRAKE PEDAL IS NECESSARY TO RESUME VEHICLE BRAKING. SUBSEQUENT BRAKING POWER IS MUCH REDUCED COMPARED TO NORMAL BRAKING AND SIGNIFICANTLY HARDER BRAKE PEDAL PRESSURE IS NECESSARY. NORMAL BRAKING MAY BE REESTABLISHED BY LIFTING THE FOOD OFF THE BRAKE PEDAL COMPLETELY AND RE-DEPRESSING THE BRAKE PEDAL. THE SEVERITY OF THE SUDDEN LOSS OF BRAKING (COMPLETE LOSS OF BRAKING) IS SHOCKING, ALARMING, AND PANIC ENDUCING AND RESULTS IN WHIPLASH TO THE VEHICLE OCCUPANTS AS THE PASSENGERS, BEING UNCONSCIOUSLY BRACED FOR DECELERATION, ARE SUDDENLY JOLTED BACK INTO THEIR SEATS. WHEN ANOTHER VEHICLE IS LOCATED IN FRONT OF THE VEHICLE THE SUDDEN LOSS OF BRAKING AND SUBSEQUENT WEAK BRAKING POWER DESPITE STRONG BRAKE PEDAL DEPRESSION IS HIGHLY ALARMING. THE MOST REPRODUCIBLE SITUATION IN WHICH THIS HAPPENS IS ON DRY PAVEMENT WHILE EXITING A HIGHWAY AND DECELERATING ON A STRAIGHT OR SLIGHTLY CURVED EXIT RAMP WITH ONE OR MORE POTHOLES. THE PHENOMENON OCCURS IN OTHER CIRCUMSTANCES AS WELL WHERE A POTHOLE IS ENCOUNTERED WHILE THE VEHICLE IS UNDER BRAKING.

I HAVE HAD THIS PROBLEM EVER SINCE I BOUGHT THIS CAR USED FROM A TOYOTA DEALERSHIP. IF I DRIVE OVER AN UNEVEN SURFACE, POTHOLE, ETC., MY CAR WILL SKIP AND THEN LURCH FORWARD. IT IS WORST ON WET ROADS. I HAVE TROUBLE STOPPING IT. ON SNOW I HAVE LITTLE TO NO TRACTION. I GOT A NEW SET OF TIRES AND I WASTED MY MONEY. NO DIFFERENCE. I DON'T FEEL SAFE DRIVING THIS VEHICLE. I HAVE BEEN DRIVING FOR YEARS, HAD MANY DIFFERENT VEHICLES, DRIVE AS PART OF MY JOB, AND HAVE NEVER EXPERIENCED ANYTHING LIKE IT. CONTACTING TOYOTA ABOUT IT WAS A WASTE OF TIME. I HAVE SPOKEN TO OTHER PRIUS 2010 OWNERS AND EVERY ONE SAYS THE SAME THING ABOUT HOW IT HANDLES WHEN GOING OVER BUMPS. THE SKIP AND LURCH COULD EASILY RESULT IN A REAR END COLLISION. I THINK THIS IS SOMETHING TOYOTA JUST DOESN'T WANT TO ADMIT TO AS BEING A PROBLEM.

Mileage: 12,500

CAR SEEMS TO LURCH FORWARD BEFORE STOPPING WHEN BRAKING ON A ROUGH SURFACE. THIS IS AN ONGOING PROBLEM.

AS MANY PREVIOUS OWNERS DESCRIBED, I AM ALSO HAVING PROBLEMS WITH THE BRAKES AT LOW SPEED SINCE THE BEGINNING OF OWNING THIS VEHICLE (OCTOBER 2009). DEALER COULDN'T REPLICATE THE PROBLEM. ALTHOUGH THE CAR WENT THROUGH THE RECALL FOR THE BREAK SYSTEM IS STILL HAVING THE SAME ISSUE EVER SINCE. THE OTHER ISSUE WITH THE BRAKES HAPPENS AFTER RAIN. IT MAKES A SCREECHING NOISE WITHOUT PERFORMANCE BEING EFFECTED. IT GOES AWAY USUALLY WITHIN A HALF AN HOUR. THIS HAS BEEN AN ONGOING THING TOO FOR FEW YEARS BY NOW. THE OTHER ISSUE I HAD AS WELL AS OTHERS IS DIMMING OF LIGHTS THAT HAS BEEN OCCURRING SINCE LAST YEAR. WE NEEDED TO SWITCH THE LIGHTBULBS MORE FREQUENTLY THAN SEEMS NORMAL. DIDN'T EVEN THINK IT WAS OUT OF THE ORDINARY UNTIL I READ THE COMMENTS HERE ABOUT IT. THE OTHER PROBLEM I STARTED TO HAVE IS WITH A STEREO DISPLAY SYSTEM AND THE VOICE ACTIVATION FOR THE BLUETOOTH. THE DISPLAY HAD SOME WEIRD LINES ON IT AFTER A VERY COLD OR A VERY HOT DAY (RADIO WAS WORKING FINE JUST THE DISPLAY WAS NOT WORKING PROPERLY). EVENTUALLY GOES BACK TO NORMAL BUT THIS STARTED HAPPENING THE LAST YEAR OR SO. THE SAME TIME ALSO HAD A PROBLEM WITH THE VOICE ACTIVATION UNIT WHICH TURNED ON UNEXPECTEDLY AND TURNED BACK ON IN 10 SECONDS AFTER EACH TIME I TURNED IT OFF. THIS WAS HAPPENING FOR A GOOD 30 MIN AT THAT TIME. THIS ONLY OCCURRED TWICE BUT BOTH TIMES WAS AFTER A HOT DAY LAST SUMMER. THIS YEAR SO FAR HAVEN'T HAPPENED YET.

WE NOTICED ALSO THAT THERE WAS A RECALL ON THIS ISSUE IN 2010 BUT OUR PARTICULAR CAR (BY VIN NUMBER) DID NOT QUALIFY. WE THINK THAT THE RECALL SHOULD HAVE INCLUDED A BROADER SAMPLE OF SAME YEAR AND MODEL. WE HAVE BROUGHT THE PROBLEM TO THE ATTENTION OF THE DEALERSHIP SEVERAL TIMES BUT THEY HAVE DISMISSED IT AS NORMAL OPERATION OF BRAKES. WE FEEL VERY UNSAFE IN THE VEHICLE.

I READ THE COMPLAINTS & FOUND ONE LISTED RECENTLY DATED 5/22/15 THAT DESCRIBES THE EXACT PROBLEM I HAVE. MY PRIUS IS A 2010 PURCHASED IN 7/09 & SHORTLY THEREAFTER, I NOTICED THE BRAKING ISSUE. THE FOLLOWING INFO IN QUOTES IS COPIED FROM THE OTHER COMPLAINT WHICH IS THE SAME ISSUE I HAVE - (OTHER COMPLAINT STATED) "WHEN YOU ARE AT LOWER SPEEDS AND HIT A POTHOLE OR BIG BUMP WHILE BREAKING, THERE'S A SUDDEN 'JOLT' AND IT FEELS AS IF THE BREAKS HAVE BEEN COMPLETELY RELEASED MOMENTARILY. IT ALMOST FEELS AS IF THE CAR LURCHES FORWARD. I FEEL IT HEIGHTENS THE CHANCE OF A CRASH DUE TO INCREASED DECELERATION TIME." IT SOMETIMES FEELS LIKE YOU ARE SLIDING ON ICE & HAVE NO CONTROL OVER THE CAR. (AND IT IS SCARY WHEN IT HAPPENS!) I HAD TOYOTA CHECK MY VEHICLE A FEW TIMES, BUT THEY WERE NOT ABLE TO DUPLICATE THE PROBLEM, SO NOTHING WAS FIXED. I THOUGHT IT WAS JUST MY CAR THIS WAS HAPPENING TO. NOW I FIND THAT I AM NOT ALONE IN THIS. THE COMPLAINT I REFERENCED STATED THAT THERE WAS AND A "PREVIOUS INVESTIGATION & PARTIAL RECALL BUT IT DIDN'T AFFECT ALL OF THE 2010 PRODUCTION VEHICLES, JUST A PORTION." I NEVER HEARD ABOUT ANY RECALL OR INVESTIGATION ON THIS. I AGREE WITH THE OTHER COMPLAINT THAT "THIS NEEDS TO BE RE-INVESTIGATED AS MY CAR AND COUNTLESS OTHER CARS (BOTH INVOLVED AND NOT INVOLVED IN THE LAST RECALL) ARE (STILL) MALFUNCTIONING WHEN IT COMES TO THE BREAKING SYSTEM AT SLOWER SPEEDS WHEN ON ROUGH ROADS / ENCOUNTERING POTHOLES / BUMPS." MY CAR STILL HAS THIS PROBLEM EVEN AS IT IS NOW 5 YEARS OLD. WHAT NEEDS TO BE DONE TO CORRECT THIS ISSUE?

I HAVE OWNED TWO PRIUS AND BOTH OF THEM HAVE HAD THE SAME BREAKING ISSUE. WHEN YOU ARE AT LOWER SPEEDS AND HIT A POTHOLE OR BIG BUMP WHILE BREAKING, THERE'S A SUDDEN 'JOLT' AND IT FEELS AS IF THE BREAKS HAVE BEEN COMPLETELY RELEASED MOMENTARILY. IT ALMOST FEELS AS THE CAR LURCHES FORWARD. I TRY TO AVOID POTHOLES, ETC ANYWAYS, BUT I AM EXTRA VIGILANT BECAUSE OF THIS ISSUE AS I FEEL IT HEIGHTENS THE CHANCE OF A CRASH DUE TO INCREASED DECELERATION TIME. LAST NIGHT, I WAS COMING UP TO AN INTERSECTION THAT HAD A YIELD SIGN. THE CAR IN-FRONT OF ME STOPPED. I HIT MY BREAKS, BUT WHILE BREAKING, I HIT A POTHOLE (IT AS DARK SO I COULDN'T SEE IT) MY BREAKS SUDDENLY BEHAVED AS DESCRIBED ABOVE - THEY LET GO FOR A MOMENT AND THE CAR SOMEWHAT JOLTED FORWARD. I WAS UNABLE TO STOP IN-TIME AND REAR-ENDED THE DRIVER AHEAD OF ME. I WAS ALWAYS AFRAID THAT BECAUSE OF THIS BREAKING ISSUE THAT THIS WOULD HAPPEN - AND NOW IT HAS. I KNOW THERE WAS A PREVIOUS INVESTIGATION AND A PARTIAL RECALL BUT IT DIDN'T AFFECT ALL OF THE 2010 PRODUCTION VEHICLES, JUST A PORTION. I FEEL THIS NEEDS TO BE RE-INVESTIGATED AS MY CAR AND COUNTLESS OTHER CARS (BOTH INVOLVED AND NOT INVOLVED IN THE LAST RECALL) ARE (STILL) MALFUNCTIONING WHEN IT COMES TO THE BREAKING SYSTEM AT SLOWER SPEEDS WHEN ON ROUGH ROADS / ENCOUNTERING POTHOLES / BUMPS.

HAVE OWNED THE CAR SINCE NEW IN 2010. BRAKES EXHIBIT THE SAME ISSUE MENTIONED IN OTHER COMPLAINTS I.E. WHEN GOING OVER BUMPY ROADS, BRAKES "RELEASE" AND RE-ENGAGE CAUSING THE CAR TO NOT STOP QUICKLY. HAD SOFTWARE RECALL DONE BUT DID NOT SIGNIFICANTLY AFFECT. HAVE JUST BEEN LIVING WITH IT BUT AFTER SEEING ALL OTHER COMPLAINTS, THOUGHT I WOULD WEIGH IN WITH THE SAME PROBLEM AS IT APPEARS TO BE A COMMON ISSUE WITH A DESIGN FLAW OF SOME SORT THAT NEEDS TO BE ADDRESSED FOR SAFETY REASONS.

CAR CAME OUT OF THE CAR WASH AND AS I GOT READY TO PULL OUT THE BRAKE LIGHT CAME ON AND THERE WAS A RAPID BEEP. PUSHED ON THE BRAKES AND FELT NO RESISTANCE LIKE BRAKES DID NOT EXIST. HAD THE CAR TOWED TO THE DEALER (RIGHT TOYOTA ON FRANK LLOYD - SCOTTSDALE AZ) - DEALER RAN A SOFTWARE TO FIX IT (PART OF A RECALL) BUT THAT DID NOT FI X THE ISSUE. DEALER ASKED ME TO HAVE HYDRO BOOSTER PUMP AND THE ASSEMBLY REPLACED - THEY CHARGED ME $4200 FOR PARTS AND LABOR. I WAS FORCED TO PAY AS THEY SAID THEY TRIED TO FIX IT THROUGHT HE SOFTWARE BUT IT DID NOT. I FEEL THAT TOYOTA IS REPSONSIBLE FOR THE SYSTEM FAILURE - THE BRAKES ARE CRITICAL - THEY SUDDENLY STOPED WORKING. IT COULD HAVE BEEN FATAL IF I WAS ON THE ROAD WHEN IT HAPPENED. THE FAILURE SHOULD BE GRADUAL AND THERE SHOULD BE A CERTAIN WARNING IF THE PUMP WAS MALFUNCTIONING. I NEED YOUR HELP IN RESOLVING THIS. TOYOTA SHOULD BE RESPONSIBELF RO PAYING THE INVOICE.

I HAVE NOTICE A DEFINITE RELEASE IN BRAKING ACTION WHEN MY 2010 PRIUS GOES OVER A PATCH OF BUMPY ROAD, WITHIN 1 MINUTE OF LEAVING MY HOME AND GOING DOWN THE BLOCK. I EXPERIENCE THIS "RELEASE" OF BRAKING AS A SUDDEN BRIEF ACCELERATION THAT OCCURS WHILE THERE IS PRESSURE ON THE BRAKE PEDAL TO SLOW DOWN WHILE GOING OVER THE BUMPY PATCH OF ROAD ( A 20 FOOT STRETCH OF ROAD WITH NUMEROUS SHALLOW POTHOLES). I BOUGH THIS CAR USED IN SEPTEMBER 2013. (IT HAD 80,000 MILES ON IT AND A HISTORY OF TRAVEL OVER GRAVEL ROADS). ON MARCH 20, 2014, THE LOCAL DEALER DID THE E0E RECALL REPAIR ON THE MOTOR GENERATOR ECU AND THE POWER MANAGEMENT ECU, TO CORRECT ISSUES RELATED TO HARD ACCELERATION. AT THE SAME TIME, THE DEALER DID THE OLDER TOYOTA RECALL REPAIR ON THE BRAKE PRESSURE ACCUMULATOR ISSUE. I HAVE NOT NOTICED THIS BRAKING RELEASE ISSUE LATER IN THE DAY. IT SEEMS TO BE MOST NOTICEABLE FIRST THING IN THE MORNING, IN THE FIRST MINUTE OR TWO OF DRIVING.

AS I WAS COMING TO A COMPLETE STOP AT AN INTERSECTION, THE CAR JOLTED AS IF I WAS HIT FROM BEHIND AND THE BRAKES LOST PRESSURE RESULTING IN ME HAVING TO PRESS THE PEDAL ALL THE WAY DOWN TO THE FLOOR. THE BRAKES WOULD NOT RESPOND AND I HAD TO PUT THE CAR IN PARK TO GET IT TO STOP. THE SAME THING HAPPENED AFTER I FIRST GOT THE VEHICLE IN 2010. IN SEPT. 2010, THE BRAKES DID NOT RESPOND, CAUSING ME TO SLIDE INTO THE ROW AND RESULTING IN AN ACCIDENT. THE CAR WILL ALSO JOLT WHEN THE BRAKES ARE PRESSED WHILE DRIVING OVER A POTHOLE OR BUMP. I TOOK THE VEHICLE IN TO HAVE THIS CHECK ON 4/2/15 AT TOYOTA OF LEWISVILLE, IN LEWISVILLE, TX. THEY CLAIM THAT EVERYTHING CHECKS OUT FINE ON THE BRAKES AND THEY CAN NOT GET IT TO REPLICATE THE JOLT OR PRESSURE FAILURE. PER TOYOTA OF LEWISVILLE, THE CAR DID HAVE A RECALL FOR THE BRAKES, WHICH WAS REPAIRED AT TOYOTA OF IRVING, BUT THE BRAKES ARE STILL EXHIBITING PROBLEMS. *TR

THIS BRAKE PROBLEMS HAS OCCURRED MANY TIMES. DURING APPLICATION OF THE BRAKES AT LOW SPEEDS ON ROUGH ROAD SURFACES THE CAR SUDDENLY LOSES BRAKING POWER FOR A BRIEF TIME THEN STARTS TO WORK AGAIN IF THE BRAKE PEDAL REMAINS DEPRESSED. THIS HAS ALMOST CAUSED ACCIDENTS A NUMBER OF TIMES AND IS QUITE FRIGHTENING. THE CAR WAS BROUGHT IN FOR THE RECALL AND SAFERCAR.GOV STATES THAT THERE ARE NO OPEN RECALLS. WHEN WE BRING THIS TO THE ATTENTION OF THE TOYOTA DEALER WE ARE TOLD THIS PROBLEM IS "NORMAL" AND THERE IS NOTHING MORE THEY CAN DO. (HOWEVER, I UNDERSTAND THAT THEY FIXED IT IN THE NEXT MODEL YEAR.)

I NOTICED THIS OCCURRING EVERY TIME I WOULD BRAKE ON AN UNEVEN SURFACE WHERE THERE WAS SPACE BETWEEN ONE OF THE FRONT TIRES AND PAVEMENT. I HAD BOUGHT THE SAME MAKE, MODEL AND YEAR VEHICLE FOR MY SON 11 MONTHS LATER AND NOTICED THE SAME PROBLEM WHILE TEST DRIVING IT. WHEN I QUESTIONED THE SALESMAN ABOUT IT I WAS TOLD THAT IT WAS THE WAY THE ABS WORKS AND THAT IT WAS NORMAL. ON 11/20/2014 WHILE CHECKING THE AIRBAG RECALL LIST I NOTICED A RECALL FOR THE SAME PROBLEM THAT I WAS HAVING, RECALL ANNOUNCED 2/9/2010, NHTSA REF # 10V03900 SO I CALLED TOYOTA CUSTOMER SERVICE 1-800-331-4331 AND WAS TOLD THAT NEITHER CARS' VIN# SHOWED IN THE RECALL SO IT COULD NOT BE HAPPENING AND I WOULD NOT BE COVERED UNDER THE RECALL.

THIS IS A CHRONIC PROBLEM WITH THE CAR: WHEN IT HITS ROUGH TERRAIN, THE BRAKES DO NOT REACT PROPERLY. THERE IS A HESITATION BETWEEN THE TIME THE BRAKE PEDAL IS HIT AND THE TIME THE CAR SLOWS.

I WAS NOT GOING FAST, MAYBE 15 MPH, AND THERE WERE NO VEHICLES IN FRONT OF ME, BUT IT COULD HAVE RESULTED IN A CRASH IF THERE HAD BEEN ANOTHER VEHICLE IN FRONT OF ME AT THE INTERSECTION. AGAIN, MY VEHICLE HAS BEEN SERVICED UNDER THE PREVIOUS RECALL, BUT I CONTINUE TO EXPERIENCE BRAKING PROBLEMS RELATED TO THE ABS. PLEASE RE-OPEN THIS INVESTIGATION AND ISSUE ANOTHER RECALL ON THIS PROBLEM. *TR

I WOULD LIKE TO FILE THIS CLAIM AS THE SAME INCIDENT DESCRIBED BELOW HAPPEN TWO TIMES IN LESS THAN TWO YEARS. THIS IS A BIG SAFETY ISSUE WHICH COULD HAVE BEEN FATAL. -- FIRST EVENT OCCURRED ON 8/17/2012 (ODOMETER 55899). BRAKE TOTALLY FAILED ON A FREEWAY AND ALMOST LOST MY LIFE THAT DAY. TOWED TO THE DEALER AND THEY REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47060, 2)GASKET, BREAK BOOST PN#44785-02060 & 3) BREAK FLUID. WHEN ASKED TO THE DEALER WHAT THE REASON FOR THE FAILURE WAS, WE WERE TOLD THAT THEY DO NOT KNOW THE CAUSE AND FAILED PART WAS SENT TO THE MANUFACTURER FOR INVESTIGATION. WE REQUESTED TO TELL US THE FINDINGS FROM THE MANUFACTURER BUT NEVER HEARD BACK AND SOON AFTER THIS INCIDENT TOYOTA HAD A RECALL FOR BREAKS. -- THE SECOND INCIDENT OCCURRED ON 7/16/2014 (ODOMETER 91965) AND SAME BRAKE FAILURE OCCURRED AGAIN AS DESCRIBED ABOVE.THIS TIME DEALER REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47140, 2) GASKET, BRAKE BOOST PN#44785-02060 & 3) BREAK FLUID. PLEASE NOTE THAT THE SECOND TIME THE BRAKE CYLINDER ASSEMBLY PN# IS DIFFERENT. WE ASKED THE DEALER AGAIN WHAT WAS THE REASON FOR FAILURE OF THE SAME PART AGAIN BUT DID NOT GET A CLEAR ANSWER FROM THEM. WE WROTE SEVERAL EMAILS TO THE DEALER BUT NO RESPONSE YET AS OF TODAY (8/19/14). I AM A VERY UNHAPPY CUSTOMER. WHAT WILL TOYOTA DO IF THIS HAPPENS AGAIN? SOON OUR WARRANTY WILL EXPIRE AND IF THIS HAPPENS AGAIN WHICH IS A TOYOTA'S EXISTING PROBLEM, HOW IT WILL BE COVERED? -- HOPE TO HEAR SOON FROM TOYOTA. *TR

VEHICLE CONTINUED FORWARD WITH NO BRAKING FOR 2 SECONDS AFTER APPLYING THE BRAKES. VEHICLE DID NOT STOP IN TIME TO AVOID STRIKING THE VEHICLE IN FRONT. FRONT BUMPER WAS DENTED AND PUNCTURED BY STRIKING THE TRAILER HITCH ON THE CAR AHEAD. NO DAMAGE TO OTHER CAR. BRAKE BOOSTER WAS REPLACED LAST YEAR UNDER RECALL FOR SAME PROBLEM. REPAIR HAS DONE NOTHING TO CORRECT THE PROBLEM. THE SAME PROBLEM HAS OCCURED INTERMITTENTLY BEFORE AND AFTER THE "FIX". BRAKES MOMENTARILY FAIL TO ACTIVATE EVERY SO OFTEN, WITH NO PARTICULAR PATTERN OR FREQUENCY. DEALER WAS NOTIFIED, AND STATED THAT UNLESS WE CAN DUPLICATE THE PROBLEM FOR THEM, THEY CANNOT PROVIDE ANY REPAIR OR ASSISTANCE. BECOMING UNEASY ABOUT USING THE CAR. WILL PROBABLY TRADE IT IN FOR SOMETHING DIFFERENT, WHICH IS NOT WHAT WE REALLY WANT. WOULD LIKE TO GET IT FIXED, AS WE LIKE THE CAR.

I BROUGHT MY 2010 PRIUS INTO THE TOYOTA MARIN (CALIFORNIA) DEALER IN JANUARY 2014 IN RESPONSE TO THEIR RECALL RELATED TO PROBLEMS WITH STEPPING ON THE BRAKE AND HAVING THE PRIUS ACCELERATE RATHER THAN STOP. THE CORRECTIVE SOFTWARE WAS PRESUMABLY INSTALLED. FAST FORWARD TO FATHER'S DAY, JUNE 15, 2014. I AM PARKING MY PRIUS FOR A FATHER'S DAY BRUNCH. I'M GOING ABOUT TWO MILES PER HOUR INTO A PARKING SPACE. I PUT MY FOOT ON THE BRAKE. THE CAR ACCELERATES. I MENTALLY DOUBLE CHECK THAT I HAVE MY FOOT ON THE BRAKE. I DO. OUT OF CONTROL, THE CAR JUMPS THE CURB AND SMASHES RIGHT INTO A TREE. MY WIFE ASKS IF MY FOOT IS ON THE BRAKE. I TRIPLE CHECK. IT STILL IS--I HAVEN'T MOVED IT. A WEEK LATER I FEEL THE TRAUMA OF CONSTANTLY VISUALIZING THE POSSIBILITY OF HAVING TRIED TO STOP AT A CROSS WALK AND KILLING A FAMILY ON THE WAY TO THEIR FATHER'S DAY BRUNCH. --IT TOOK THREE DAYS OF CONSTANT CALLING AND DYSFUNCTIONAL EXTENSIONS TO CONNECT WITH A PRIUS CASE MANAGER. THEN SHE INFORMED ME IT WOULD TAKE ME MORE THAN A MONTH TO HAVE MY CAR INSPECTED AND GET AN ASSESSMENT. IF I RENTED A CAR THERE WOULD BE NO ASSURANCE IT WOULD BE COVERED. --THIS PROBLEM HAPPENED AFTER I RESPONDED TO THE RECALL. HOW CAN I TRUST A CAR THAT IS AUTOMATICALLY CRASHING AFTER THAT PRECISE PROBLEM HAS ALLEGEDLY BEEN ADDRESSED? --I JUST RECEIVED (JULY 19, 2014) A LETTER FROM TOYOTA SALES SAYING THE CAR'S BRAKES AND ACCELERATOR WERE TESTED AND "ALL IS FINE." HOWEVER, IN MY AND OTHERS' SIMILAR EXPERIENCES THE SURGE HAPPENS ONLY OCCASIONALLY. WE BOUGHT THE CAR USED, HAVE GONE ABOUT 20,000 MILES WITH IT, AND NEVER HAD THE PROBLEM. SO A TEST EVEN FOR A YEAR AT A TIME IS IRRELEVANT. --MY "ASK": SINCE OTHERS SHARE THIS EXPERIENCE AND IT COULD RESULT IN DEATH, I WANT TOYOTA TO SELL THIS CAR FOR PARTS AND RECALL THE 2010 PRIUS UNTIL A SOLUTION CAN BE FOUND. I AM SHOCKED AT PRIUS' IRRESPONSIBILITY. *TR

BACK IN 2010, WE NOTICED THAT, WHEN BRAKING, THE CAR WOULD LURCH FORWARD. THIS HAPPENED SEVERAL TIMES AT RANDOM. AT THAT TIME, WE TOOK THE CAR IN TO FIX THE PROBLEM. VICTORY TOYOTA IN CANTON, MICHIGAN, TOLD US THAT THERE WAS NOTHING WRONG; THEIR DIAGNOSIS AND COMPUTERS SHOWED THAT NO ERRORS HAD OCCURRED. WE DROVE IT FOR A SHORT TIME, AND IT CONTINUED TO HAVE THE ISSUE. WE TOOK IT BACK IN TO THE DEALERSHIP, THEY AGAIN SAID THAT THERE WAS NOTHING WRONG. THEY SAID THAT THEY TOOK IT FOR A TEST DRIVE, AND NOTHING HAPPENED. WE WERE MADE TO THINK THAT THE ISSUE WAS IN OUR HEADS, SO WE TOOK THE CAR BACK AND TRIED TO DEAL WITH THE ISSUE, EVEN THOUGH IT CONTINUED OVER THE YEARS. FINALLY, THIS YEAR, WE NEARLY GOT INTO TWO SEPARATE ACCIDENTS AS A DIRECT RESULT OF THIS SUDDEN LURCHING FORWARD. I TOOK THE CAR BACK INTO THE SERVICE DEPARTMENT OF VICTORY TOYOTA, AND WAS TOLD BLUNTLY THAT THERE WAS NEVER A RECALL FOR THIS ISSUE, THAT, UNLESS I COULD RECREATE THE PROBLEM WITH A TECHNICIAN IN THE CAR, I WAS MAKING THINGS UP. THAT IS WHAT LEAD TO THIS COMPLAINT. I DID SOME RESEARCH AND FOUND THAT THE CAR HAD INDEED BEEN RECALLED FOR THIS BRAKE ISSUE WITH RECALL ID # 68066. SO THEY LIED ABOUT THE RECALL HISTORY FOR MY CAR. ALSO, RECREATING SOMETHING THAT HAPPENS AT RANDOM DURING A FINITE TIME PERIOD, SUCH AS A TEST DRIVE, IS IMPROBABLE, AND TO MAKE SERVICING THE CAR CONTINGENT ON THAT TEST DRIVE IS LUDICROUS. I AM HOPING THAT, BY LODGING THIS COMPLAINT SOMETHING WILL GET DONE BEFORE MY WIFE, ME, OR/AND SOMEONE ELSE IS/ARE KILLED BECAUSE OF THIS ISSUE. *TR

I OWN A 2010 PRIUS, WHEN THE BRAKES ARE APPLIED, THE BRAKE PEDAL IS EVEN WITH THE ACCELERATOR PEDAL. I FIND THIS A DANGEROUS SITUATION. IF I WERE TO APPLY THE BRAKES SUDDENLY, MY FOOT COULD POSSIBLY HIT THE ACCELERATOR PEDAL AND THE BRAKE PEDAL AT THE SAME TIME POSSIBLY CAUSING AN ACCIDENT! I COMPLAINED TO THE TOYOTA DEALER, AND WAS TOLD THE BRAKE PEDAL IS LOWER ON THE PRIUS THEN CONVENTIONAL VEHICLES.I WAS ALWAYS TAUGHT THAT THE BRAKE PEDAL SHOULD NEVER BE AT THE SAME HEIGHT OR BELOW THE ACCELERATOR PEDAL FOR SAFETY REASONS. TOYOTA APPEARS TO IGNORE THIS SAFETY ISSUE. HAVEN'T AUTO MFG. LEARNED ANYTHING WITH GM IGNITION PROBLEM? WHEN IS THE GOVERNMENT GOING TO DO SOMETHING ABOUT THESE AUTO DESIGN DEFECTS? ARE THEY ALWAYS GOING TO WAIT FOR PEOPLE TO GET INTO ACCIDENTS AND POSSIBLY GET KILLED BEFORE THEY ACT? *JS

EVER SINCE ACQUIRING THIS VEHICLE EARLIER THIS YEAR, I HAVE BEEN EXPERIENCING LOSS OF BREAKING FOR A SECOND EVERY TIME I HIT A POTHOLE AND BUMPY SPOT. IT HAPPENS EVERY OTHER TIME. UPON GOGGLING THIS PROBLEM, I LEARNED THAT THE PROBLEM WAS FIRST REPORTED TO NHTSA WAY BACK IN 2009. BUT I DO NOT SEE ANY RECALLS RELATED TO THIS PROBLEM. YOUR WEBSITE SAYS YOU HAVE RECEIVED ABOUT 33 COMPLAINS. UNLESS I MISSED SOMETHING, IS THERE ANY STATUS REPORT FROM TOYOTA OR THE RECALL THAT SPECIFICALLY ADDRESSES THIS PROBLEM? ALSO, I LIVE IN THE EAST COAST, SPECIFICALLY IN NJ. WE HAD A BRUTAL WINTER THIS YEAR. IN ONE INCIDENT, I WAS DRIVING UP A SLIGHTLY ELEVATED ROAD (BARELY 2--5% INCLINE) IN A 25MPH RESIDENTIAL ROAD WITH SLIGHTLY SLIPPERY ROAD (NOT REALLY BLACK ICE PER SE). I LOSS CONTROL AND TRACTION CONTROL LITE UP AND STARTED BEEPING. WHILE TRYING TO BRING THE CAR IN CONTROL, MY CAR ENDED UP ON THE OTHER SIDE (THANKFULLY THERE WERE NO VEHICLES PARKED ON THE OTHER SIDE OR ANY ONCOMING VEHICLES) AND THEN SHIFTED TO THE RIGHT BUT FINALLY MANAGED TO BRING IT BACK IN CONTROL. OTHER MISC INFORMATION: I LEARNED ABOUT A RECALL EARLIER THIS YEAR RELATED TO ECU BOARD PROGRAMMING UPDATE FROM THE NEWS MEDIA (SINCE I WAS A NEW OWNER, TOYOTA PROBABLY DIDN'T HAVE MY INFORMATION SO NEVER GOT RECALL NOTICE) AND I WENT TO THE DEALER FOR UPDATE. I WAS HOPING SOFTWARE UPDATE MIGHT ALSO ADDRESS POTHOLE/LOSS OF BREAK PROBLEM BUT IT HAS NOT HELPED. *TR

THIS HAS OCCURRED ON MULTIPLE INCIDENTS. THIS CAR DOES NOT STOP PROPERLY ON ROUGH ROADS. WHEN HITTING A POTHOLE, BUMP, MANHOLE COVER, ROUGH ROAD WHILE APPLYING THE BRAKES, INSTEAD OF STOPPING, THE CAR SURGES FORWARDS APPROXIMATELY 5-10 FEET AS THOUGH THERE WERE NO BRAKES. EVENTUALLY, THE BRAKES WORK AND THE CAR STOPS. BUT IT CAN BE REALLY SCARY. I HAVE TAKEN IT TO TOYOTA SEVERAL TIMES, BUT THEY CANNOT "REPLICATE THE INCIDENT." BASICALLY, I THINK THEY DRIVE IT AROUND THE BLOCK AND IT DOESN'T HAPPEN. IT IS ALWAYS WORSE WITH THE SUMMER TIRES VS THE STUDDED WINTER TIRES. THEY SAY IT HAS TO DO WITH THE REGEN BRAKES SWITCHING TO THE ANTI-LOCKS, BUT I REGULARLY DRIVE RENTAL CARS WITH ANTI-LOCKS FOR WORK IN OTHER CITIES, AND I KNOW WHAT ANTI-LOCKS FEEL LIKE. I HAVE NEVER FELT THE "CHATTER" ONE FEELS WHEN THE ANTI-LOCKS KICK ON. I DO NOT BELIEVE THE ANTI-LOCKS WORK PROPERLY ON THIS CAR. ON MAY 3, 2012, I HAD TO REPLACE THE RIGHT REAR BRAKE (ROTOR, PLATE, PADS) DUE TO UNEXPECTED CORROSION. MY CAR HAD ~17-18,000 MILES ON IT AND WAS ONLY 1.5 YEARS OLD! I HAVE NEVER HAD TO DO THIS ON ANY OTHER CAR. NOW AT 27, 000 MILES, MENDENHALL TOYOTA SAYS I NEED TO REPLACE THE REAR BRAKES AGAIN . I JUST REPLACED THE FRONT BRAKE PADS LAST WEEK. BUT THERE IS A NASTY SQUEAL THAT I REPORTED TO THEM LAST WEEK AND THEY DID NOTHING. EITHER THEY ARE RIPPING ME OFF OR THE BRAKES ON THESE CARS ARE DEFECTIVE AND DANGEROUS. PLEASE DO SOMETHING.

APPLYING BRAKES, EITHER GRADUALLY OR WITH FORCE, WHILE FRONT LEFT OR FRONT RIGHT TIRE TRAVELS OVER A POTHOLE OR SUNKEN MANHOLE COVER RESULTS IN TEMPORARY (< 1 SECOND) COMPLETE LOSS OF BRAKING POWER. BRAKE PEDAL IS DEPRESSED THROUGH THE ENTIRE DURATION OF THE INCIDENT. LOSS OF BRAKING POWER RESULTS IN DRIVER APPLYING BRAKE WITH MORE FORCE. WHEN BRAKES RESUME POWER, THE INCREASED FORCE RESULTS IN A SUDDEN DROP IN SPEED. THIS INCIDENT INCREASES THE RISK OF A REAR END COLLISION EITHER TO A VEHICLE IN FRONT OR FROM A VEHICLE BEHIND THE PRIUS. *TR

WHEN APPLYING LIGHT TO MODERATE BRAKING IN PREPARATION TO MAKE A RIGHT TURN, I WENT OVER SOME BUMPY PAVEMENT AND THE CAR SEEMED TO LURCH FORWARD. IT WAS PROBABLY A LOSS OF BRAKING RATHER THAN ACTUAL ACCELERATION, BUT IT WAS VERY DISCONCERTING AND I'M LUCKY IT DIDN'T CAUSE AN ACCIDENT. I NOW HAVE OVER 49,000 MILES ON THE CAR AND THIS HAS HAPPENED ON QUITE A FEW OCCASIONS. I KNOW THERE WAS A RECALL ON SOME 2010 PRIUS VEHICLES FOR THIS PROBLEM BUT MY CAR WAS NOT RECALLED. MY DEALER SAYS THERE IS NO "SOFTWARE FIX" FOR THIS PROBLEM. I FIND IT UNACCEPTABLE THAT TOYOTA DOESN'T HAVE A SOLUTION FOR THIS AS IT IS A REAL SAFETY ISSUE. IT'S JUST PURE LUCK THAT I HAVEN'T BEEN INVOLVED IN AN ACCIDENT WITH POSSIBLE INJURIES OR WORSE. I INTEND TO PURSUE THIS AGAIN WHEN I BRING THE CAR IN FOR THE 50,000 MILE SERVICE AND INVERTER RECALL, BUT I'M NOT VERY HOPEFUL.

LUCKILY HE WAS JUST GETTING OUT OF THE PARKING LOT, SO HE WAS DRIVING SLOWLY. WHEN HE STEPPED ALL THE WAY DOWN ON THE BRAKE, IT HAD THIS LOUD METAL RATTLING NOISE, AND HE WAS ABLE TO STOP. WE TOWED THE CAR TO TOWN AND COUNTRY TOYOTA ON SATURDAY, THE ASSISTANT SERVICE MANAGER SAID HE'S NEVER SEEN IT BEFORE, AND THE ERROR CODE SHOWN DURING DIAGNOSIS IS A CODE THEY'VE NEVER SEEN. THE MESSAGE ASKED THEM TO CONTACT TOYOTA TECHNICAL SERVICE. ON MONDAY 02/10, THE DEALER CALLED AND TOLD US THAT IT WILL COST OVER $4500 TO FIX IT. WE BOUGHT THE CAR IN FEB 2011 AS BRAND NEW CAR, SO IT'S JUST 3 YEARS OLD. I THEN CONTACTED TOYOTA CUSTOMER SERVICE, AND REQUESTED THAT TOYOTA COVERS THE REPAIR. I WAS TOLD THAT THERE IS NO RECALL PROGRAM RELATED TO THIS PROBLEM, AND THAT IF I RUN INTO THE SAME SITUATION AGAIN, OR OTHER PEOPLE RUN INTO THE SAME ISSUE, THEN TOYOTA MIGHT CONSIDER A RECALL, AND WOULD REFUND ME FOR THE REPAIR. THIS IS A VERY DANGEROUS SITUATION THAT I HOPE I'LL NEVER RUN INTO IT AGAIN EVER! IT JUST SEEMS TOYOTA IS VERY COLD AND INDIFFERENT TO PEOPLE'S SAFETY. *TR

THE ABS/BRAKE/STABILITY LIGHTS ARE "ON" PRIUS DASH. THE BRAKE LOST PRESSURE AND MUSHY. THE BRAKE MUST BE PUMPED A FEW TIMES TO GET PRESSURE AND TO STOP THE CAR. EITHER THIS IS ABS ACCUMULATOR(JUST FOUND OUT THERE IS A RECALL WHILE GETTING DEALER APPOINTMENT) FAILURE OR BRAKE MASTER CYLINDER FAILURE. THERE IS NO FLUID LEAK VISIBLE OUTSIDE OR INDICATOR LIGHT BUT THE FLUID IS ALMOST EMPTY IN THE RESERVOIR. I DON'T HAVE DEALER DIAGNOSIS AT THIS POINT YET. I'M NOT SURE IF THE ACCIDENT I HAVE ON 1/27/2014 THAT I'VE REAR-ENDED ANOTHER VEHICLE WHILE TRAVELING ABOUT 30-35MPH AND TRIED TO STOP BUT THE CAR DID NOT STOP AND BUMPED INTO THE CAR IN FRONT. FORTUNATELY, THERE IS INJURY OR MAJOR DAMAGES. AT THAT TIME I DIDN'T THINK OF IT THAT THE BRAKE MAY HAVE ISSUE OR NOT BUT THINKING BACK THE BRAKE DIDN'T HAVE ENOUGH BITE TO STOP EVEN THOUGH THE CAR IS TRAVELING SLOW ENOUGH AND THERE IS AMPLE DISTANCE.

ON OCTOBER 10TH, 2013 AT 7 PM, I NOTICED SEVERAL BRAKE LIGHTS, ABS, AND SLIDING SIGN LIGHT CAME ON WHEN I STARTED MY CAR. I THOUGHT IT WAS SOME KIND OF ELECTRICAL GLITCH SO I TURNED MY CAR OFF AND TURNED IT BACK ON. THE LIGHTS STAYED SAME. MY HUSBAND WHO SAT ON THE PASSENGER SIDE LOOKED INTO THE MANUAL BOOK AND TOLD ME THOSE LIGHTS WERE INDICATED FOR BRAKE SYSTEM. WE DECIDED TO GO HOME TO FIGURE OUT WHAT WE NEEDED TO DO. AS SOON AS I STARTED TO DRIVE, I NOTICED BRAKE PEDAL WAS MUCH LOWER THAN IT USUALLY IS AND ALSO NOTICED BRAKE WAS NOT WORKING. MY CAR KEPT MOVING EVEN WHEN I PRESSED THE BRAKE ALL THE WAY. AT THAT MOMENT, I KNEW I HAD TO TAKE MY CAR TO DEALER RIGHT AWAY. THERE WERE NO WARNING SIGNS OR NOISE FOR A DRIVER TO NOTICE BEFORE THE WHOLE BRAKE SYSTEM WAS COMPLETELY FAIL TO PERFORM. IN JANUARY 2013, TOYOTA RECALLED MANY PRIUS IN SAME MODEL AND SAME YR AS MINE FOR TOTAL BREAK SYSTEM FAILURE. EVEN THOUGH MY VIN NUMBER WAS NOT UNDER THEIR RECALL LIST, MY CAR'S BRAKE SYSTEM BROKE DOWN COMPLETELY TO FUNCTION DUE TO SAME REASONS TOYOTA RECALLED MANY PRIUS 2010 THIS YEAR. TOYOTA REFUSED TO FIX MY CAR UNDER THEIR RECALL SYSTEM WARRANTY BECAUSE MY VIN NUMBER IS NOT UNDER THEIR RECALL LIST. TOYOTA DEALER CHARGED ME $4300 TO REPLACE THE WHOLE BRAKE SYSTEM FOR MY CAR AND IT TOOK 4 WEEKS TO FIND THE PARTS IN NORTH AMERICA TO FIX MY CAR. IT COST ME ANOTHER $1000 TO RENT A CAR WHILE MY PRIUS AT TOYOTA DEALER TO FIND THE PARTS TO FIX IT. I WAS FORTUNATE ENOUGH THAT MY BRAKE SYSTEM DIDN'T BLOW OUT ON ME WHEN I WAS DRIVING 75MPH ON FREEWAY. I'M SURE THERE ARE MANY OTHER PRIUS 2010 HAVE BRAKE SYSTEM FAILURE LIKE MINE EVEN THOUGH THEY WERE NOT UNDER THEIR RECALL LIST. *TR

THE CAR IN FRONT OF ME STOPPED ABRUPTLY AND I SLAMMED ON MY BRAKES. I HELD THEM TO THE FLOOR AND THE CAR CONTINUED AT THE SAME SPEED INTO THE REAR END OF THE CAR IN FRONT OF ME. I WAS AT LEAST 1 AND 1/2 CAR LENGTHS AWAY WHEN I SLAMMED ON THE BRAKES. I HAVE BEEN TOLD BY STATE FARM INSURANCE THAT THERE WAS A RECALL ON THE 2010 PRIUS. I WAS TOLD MY MY TOYOTA CAR DEALER THAT MY CAR WAS BUILT IN MARCH 2010 AND THUS WAS NOT PART OF THE RECALL. I PURCHASED THIS CAR IN 11/13. IS THERE A WAY TO VERIFY EXACTLY WHICH DAY MY CAR WAS BUILT? *TR

THIS HAPPENED MORE THEN ONCE, ALL PRETTY MUCH THE SAME WAY. WHILE DRIVING APPROXIMATELY 30 MPH, APPLYING THE BRAKES COMING TO A STOP AND TRAVELING OVER A ROUGH ROAD THE BRAKES FEEL LIKE THEY RELEASE AND THE VEHICLE DOES NOT STOP. AFTER THE VEHICLE PASSES THE ROUGH ARE I HAVE TO RELEASE THE BRAKES AND REAPPLY PRESSURE TO THE BRAKE PEDDLE FOR THE VEHICLE BRAKES TO REENGAGE AND STOP THE FORWARD MOMENTUM. LAST MONTH WHEN I TOOK THE VEHICLE TO DEALER IN OLYMPIA WA, I ASKED THEM TO CHECK FOR ANY RECALLS AND MAKE A NOTE OF THE ISSUE. THIS ISSUE HAS ALMOST CAUSE AN ACCIDENT. *TR

I BELIEVE THE NHTSA SHOULD INVESTIGATE WHETHER TOYOTA HAS UNDERSTATED THE NUMBER OF 2010 PRIUS CARS WITH POTENTIALLY FAULTY BRAKE ACCUMULATOR PUMPS. THE COMPANY RECALLED THOUSANDS OF THE CARS MANUFACTURED BETWEEN JUNE AND OCTOBER, 2009. MY DEALER RECENTLY TOLD ME THAT MY 2010 PRIUS, MANUFACTURED IN DECEMBER, 2009 ? JUST TWO MONTHS LATER ? HAS ESSENTIALLY THE SAME PROBLEM. THEY INFORMED ME THAT THIS IS A ?SAFETY CONCERN? AND THAT THE PUMP SHOULD BE REPLACED ?AS SOON AS POSSIBLE,? AT A COST OF OVER $4,000. BUT BECAUSE MY CAR WAS MANUFACTURED TWO MONTHS AFTER THE LAST CARS COVERED IN THE RECALL, THEY HAVE REFUSED TO PAY FOR THE REPLACEMENT. I AM VERY DOUBTFUL OF THE IDEA THAT PROBLEM AFFECTING MY CAR IS DIFFERENT FROM THE DEFECT RESULTING IN THE RECALL. FIRST, THE KEY ISSUE IS ESSENTIALLY IDENTICAL: CONTAMINATED FLUID THAT COULD RESULT IN A LOSS OF BRAKING POWER. SECOND, THE CAR IS THE SAME MODEL AND YEAR AS THOSE RECALLED, JUST MANUFACTURED A COUPLE OF MONTHS LATER. THIRD, THIS SORT OF REPAIR ? THE NEED TO REPLACE A SINGLE, VERY EXPENSIVE COMPONENT LESS THAN FOUR YEARS AFTER PURCHASE ? OUGHT TO BE RARE. IF IT?S NOT, THIS SUGGESTS A SYSTEMATIC DIFFICULTY. *TR

UPON BRAKING OVER A BUMP, POTHOLE, WET LEAVES AND/OR ANY COMBINATION OF THE AFOREMENTIONED CIRCUMSTANCES, THE PRIUS ACCELERATES FORWARD, THUS CREATING A VERY UNSAFE DRIVING CONDITION. SINCE I ORIGINALLY PURCHASED THE VEHICLE, IT HAS DONE THIS ON NUMEROUS OCCASIONS. I DO NOT FEEL SAFE DRIVING THIS VEHICLE AND AM AFRAID THAT THIS BRAKING ISSUE MAY RESULT IN AN ACCIDENT THAT OTHERWISE WOULD HAVE BEEN A NON-ISSUE FOR ANY OTHER VEHICLE. IN MY 19+ YEARS OF DRIVING, I HAVE NEVER HAD A VEHICLE DO THIS WHILE BRAKING. I, THEREFORE, IMPLORE THE NTSB TO DUTIFULLY CARRY OUT ITS MISSION STATEMENT OF PROTECTING MOTORISTS BY FORCING TOYOTA TO RECALL SAID VEHICLE IN ORDER TO PROPERLY REMEDY THIS ISSUE BEFORE PREVENTABLE ACCIDENTS OCCUR AND LIVES ARE POTENTIALLY LOST. *TR

COMING TO A STOP LIGHT, I APPLIED THE BRAKES. THIS HAS BEEN AN ONGOING ISSUE WITH MY CAR THAT WHEN APPLYING THE BRAKES AND A BUMP IN THE ROAD IS DETECTED, THE CAR SUPPOSEDLY SWITCHES TO ABS BRAKING. THE NET EFFECT OF IT IS THAT THE BRAKES TEMPORARILY DISENGAGE CAUSING THE CAR TO ACCELERATE FOR A BRIEF PERIOD UNTIL YOU REAPPLY THE BRAKES AND EVENTUALLY COME TO A STOP. SO AS A RESULT, THE FROM THE MOMENT YOU APPLY THE BRAKES TO THE TIME YOU STOP, THERE IS A "LURCHING FORWARD" OF ABOUT 5 FEET UNDER WHICH YOU HAVE NO CONTROL OVER THE CAR. THAT IS QUITE SCARY SINCE IF PER CHANCE A PERSON WERE CROSSING THE ROAD WHILE YOUR CAR HIT A BUMP IN THE ROAD, YOUR VEHICLE COULD THEORETICALLY HIT THE PERSON BEFORE THE BRAKES HAD A CHANCE TO KICK IN. I'VE CHECKED THE BLOGS AND HAVE NOTICED THAT PEOPLE WITH PRIUSES FROM VARIOUS YEARS HAVE REPORTED THE SAME PROBLEM. I NOTICED THIS PROBLEM EARLY ON IN MY OWNERSHIP OF THE CAR, AND ACTUALLY ASKED THE DEALER TO FIX THE PROBLEM. THEY REPORTED TO ME THAT EVERYTHING WAS WORKING PROPERLY. I THEN ASKED THEM TO TEST DRIVE IT FOR A WHILE TO REPRODUCE THE PROBLEM. THEY HAD MY CAR FOR A WEEK AND SUPPOSEDLY WERE UNABLE TO REPRODUCE THE PROBLEM. THERE WAS AN ABS RECALL BY PRIUS AND THEY SUPPOSEDLY APPLIED THE FIX TO MY CAR, BUT I HAVE SINCE NOTICED THE SAME ISSUE. *TR

THE ABS SYSTEM ON MY 2010 PRIUS SEEMS TO RELEASE THE BRAKE WHEN APPLIED ON ROUGH SURFACES GOING DOWNHILL WHICH GIVES A SENSE OF ACCELERATION AND LACK OF VEHICLE CONTROL.

I'M AM NOW CONCERNED ABOUT THE BRAKE SYSTEM INTEGRITY WHEN I DRIVE AND FEEL STRONGLY THAT THE NHTSA SHOULD INITIATE AN IN DEPTH INVESTIGATION INTO THIS SITUATION. *TR

THEN I START RESEARCHING AND WHILE CAR IS NOT INCLUDED IN ANY RECALLS, IT'S THE SAME PROBLEM INVESTIGATED IN NTSB 10V039000. EXACTLY! CAR IS STILL AT DEALER, AS I HAVE ASKED TO SPEAK TO SERVICE MGR.

THIS INCIDENT HAS OCCURRED NUMEROUS TIMES SINCE PURCHASING THE CAR, BUT IT WASN'T UNTIL LAST WEEK (9/6/2013) THAT I BECAME TERRIFIED AS I ALMOST HIT ANOTHER VEHICLE IN FRONT OF ME. WHENEVER MY PRIUS RUNS OVER A POTHOLE, BUMP, UNEVEN SURFACE, OR DEEP MANHOLE COVER AS I AM BRAKING TOWARDS AN INTERSECTION TO COME TO A STOP (FOR ME, ALL THESE INCIDENTS OCCURRED WHEN I APPROACHED AN INTERSECTION) THE BRAKES STOP WORKING FOR A BRIEF MOMENT AND SUDDENLY MY CAR JERKS FORWARD, LURCHES FORWARD, OR ACCELERATES. I HAVE TO PRESS DOWN MY BRAKES REALLY HARD TO THE FLOOR TO STOP THE VEHICLE WHEN THIS HAPPENS. WHEN THIS FAILS, I IMMEDIATELY RELEASE THE BRAKE AND RE-APPLY VERY HARD TO THE FLOOR TO STOP THE CAR. IN THESE MOMENTS IT BECOMES SCARY AS I AM NEVER SURE IF THE CAR WILL COME TO A STOP BEFORE THE INTERSECTION. LAST WEEK, I WAS APPROACHING A BUSY INTERSECTION WHILE BRAKING AND I RAN OVER A UNEVEN POTHOLE COVER/FILLER AT ABOUT 5 TO 15 MPH WHICH CAUSED MY CAR TO ACCELERATE TO LIKE 20 OR 25 MPH! I HAD TO BRAKE VERY HARD IN ORDER TO STOP MY CAR AND SWERVE TO THE RIGHT TO AVOID HITTING THE CAR IN FRONT OF ME. THIS PROBLEM ONLY OCCURS WHEN MY RIGHT SIDE TIRES HIT THE UNEVEN SURFACE, MANHOLE COVER, POTHOLES, BUMPS, ETC. I HAVE NOT HAD AN INCIDENT WHERE IT HAPPENED WITH THE LEFT TIRES. TOYOTA SERVICE HAS SAID THERE IS NO PROBLEM WITH MY CAR'S BRAKES AND THEREFORE SAID THEY CAN'T FIX ANYTHING. THERE IS A PROBLEM WITH TOYOTA'S PRIUS BRAKING SYSTEM. *TR

THIS VEHICLE SHOULD BE PART OF THE LARGER TOYOTA RECALL ON BRAKES THAT WAS ANNOUNCED EARLIER THIS YEAR. AFTER A FEW THOUSAND MILES, I NOTICED THAT THE BRAKES GAVE WAY IF THE PRIUS HITS A BUMP OR POTHOLE. TOYOTA'S STATEMENT THAT "CUSTOMERS ARE PERCEIVING INCONSISTENT BRAKE FEEL DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES" IS AN UNDERSTATEMENT. THE BRAKES DON'T ACTUALLY WORK WHEN YOU ARE DECELERATING AND HIT A BUMP, WHICH IS PROBLEMATIC WHEN YOU LIVE IN A CITY NOTORIOUS FOR POTHOLES. I REPORTED THIS ISSUE EARLY ON TO MY DEALER, AND HAVE SINCE FOLLOWED UP, EACH TIME BEING MET WITH THE SAME RESPONSE: THERE ARE NO REPORTS ON THIS ISSUE. FOR WHATEVER REASON, TOYOTA FEELS THAT ONLY CERTAIN VIN LOT NUMBERS MERIT THE RECALL, BUT I CAN ASSURE THEM THE PROBLEM IS MORE WIDESPREAD. MOST OWNERS I'VE TALKED TO HAVE TRIED TO ACCOMMODATE THE PROBLEM BY BEING AWARE OF BUMPS WHEN COMING TO A STOP, BUT AT SOME POINT SOMEONE WILL INJURE OR KILL SOMEONE ELSE AS A RESULT OF THIS BRAKING ISSUE. *TR

THIS INCIDENT HAS OCCURRED TWICE UNDER IDENTICAL CONDITIONS, IN THE SAME LOCATION. THE CAR DID NOT ENGAGE THE BRAKES UNTIL APPROXIMATELY ONE SECOND AFTER I DEPRESSED THE PEDAL. MAYBE THE COMPUTER'S ELECTRONIC STABILITY CONTROL IS INVOLVED IN THE PROBLEM, EVEN THOUGH THE CAR DID NOT INDICATE THAT ELECTRONIC STABILITY CONTROL WAS ENGAGED. BOTH TIMES I WAS DRIVING ON A SLIGHT DOWNHILL AT ~20 MPH. IMMEDIATELY AFTER I PASSED OVER SOME BUMPS, I DEPRESSED THE BRAKES, AND THERE WAS A SIGNIFICANT DELAY IN THE BRAKES BEING ENGAGED (1S). I THINK THE BUMPS IN THE ROAD ARE INVOLVED IN THIS ISSUE. OF NOTE, THIS CAR UNDERWENT AN UPDATE TO ITS SOFTWARE PROGRAM FOLLOWING A RECALL INVOLVING BRAKING PROBLEMS, AND THESE INCIDENTS OCCURRED AFTER THE UPDATE. *JB

WHILE BRAKING OVER AN UNEVEN SURFACE COMING UP TO A STOP LIGHT, THE CAR LURCHED FORWARD, CAUSING IT TO SEEMINGLY ACCELERATE INTO THE CROSSWALK. I WAS COASTING UP TO THE STOPLIGHT AND APPLIED THE BRAKES CLOSER TO THE LIGHT, AS THE CAR WAS TRAVELING OVER THE UNEVEN SURFACE. THE UNEVEN SURFACE WAS CAUSED BY RAISED METAL PLATES COVERING ROAD CONSTRUCTION. THE VEHICLE WAS TRAVELING ABOUT 5-10 MPH AND DECELERATING AT THE TIME OF THE INCIDENT. THIS HAS HAPPENED WITH REGULAR CONSISTENCY EVEN THOUGH THE CAR GOT THE SOFTWARE FIX WITHIN A FEW MONTHS OF PURCHASE IN 2010.

WHILE BRAKING AT LOW SPEEDS -- SUCH AS WHILE APPROACHING A TRAFFIC LIGHT OR AN INTERSECTION -- PASSING OVER A POTHOLE OR UNEVEN ROAD SURFACE OFTEN CAUSES THE BRAKES TO DISENGAGE. THE SENSATION IS ONE IN WHICH MY FOOT IS IN THE SAME PLACE AS IT WAS WHEN I BEGAN BRAKING, BUT SUDDENLY THERE IS NO GIVE TO THE PEDAL, THE BRAKING HAS STOPPED -- BRAKING DOES NOT RETURN UNTIL I PUSH FURTHER DOWN ON THE PEDAL. MY FOOT IS NOT DISLODGED BY THE BUMP, AND THE BRAKING MECHANISM WILL NOT RE-ENGAGE UNLESS I PUSH THE PEDAL TO A NEW, DEEPER LOCATION. IT IS OBVIOUSLY DISCONCERTING AT INTERSECTIONS, AND SINCE MOVING TO A NEW LOCATION AND HAVING TO RE-LEARN WHERE ON MY ROUTES THIS PROBLEM WILL OCCUR, I DECIDED IT WAS TIME TO FILE A COMPLAINT. THE FRUSTRATION IS THAT THIS ISSUE WAS SUPPOSEDLY SOLVED A COUPLE YEARS AGO WITH A SOFTWARE FIX FROM TOYOTA, BUT THAT FIX SEEMS TO NOT HAVE WORKED. I FILED A COMPLAINT ABOUT THE PRIUS PROBLEM WITH SOME AGENCY (POSSIBLY NHTSA OR FTC) A FEW YEARS AGO WHEN THE OTHER, MORE NOTABLE, BRAKE-STICKING PROBLEM IN OTHER TOYOTAS WAS IN THE NEWS.

IN THIS SITUATION, THE FEEDBACK FROM THE VEHICLE SUGGESTS THAT THE BRAKES HAVE DISENGAGED. BASED UPON 2+ YEARS OF ADDITIONAL EXPERIENCE, I WOULD NOTE THAT: (1) THIS ANOMALY OCCURS CONSISTENTLY, AND IT HAS NOT DISAPPEARED OR ATTENUATED, (2) I BELIEVE THAT STOPPING DISTANCES ARE LONGER THAN WOULD BE EXPECTED WITHOUT THIS ANOMALY, (3) MY PRIUS WAS MANUFACTURED AFTER THE 2010 SOFTWARE FIX, AND (4) OTHER DRIVERS OF 2010 AND LATER PRIUS CARS HAVE REPORTED THE SAME PHENOMENON WHEN I ASKED ABOUT IT (SEE BELOW). MOST IMPORTANTLY, I WOULD NOTE THE FOLLOWING SOURCE OF EVIDENCE WHICH YOU MIGHT EASILY PURSUE FURTHER. I HAVE BEEN LIVING IN NEW YORK CITY (NYC) FOR MOST OF THE LAST TWO YEARS. THE NYC TAXI FLEET INCLUDES A SIZABLE NUMBER OF TOYOTA PRIUS CARS. EVERY TIME I TAKE A PRIUS TAXI, I ASK THE DRIVER IF HE HAS ENCOUNTERED A SIMILAR PROBLEM WHEN BRAKING ON ROUGH SURFACES. IN MORE THAN A DOZEN SUCH INSTANCES, DRIVERS HAVE CONSISTENTLY REPORTED THIS SAME PROBLEM. WHILE YOU MAY NOT WANT TO TRUST MY EVIDENCE ON THIS MATTER, IT WOULD BE VERY CHEAP FOR NHTSA TO SEND AN INVESTIGATOR TO SOME OF THE LARGE TAXI GARAGES IN NYC TO INTERVIEW DRIVERS WITH EXPERIENCE DRIVING PRIUS TAXI CABS. GIVEN THE LARGE NUMBER OF MILES LOGGED BY TAXI DRIVERS, THIS COULD BE AN IMPORTANT SOURCE OF INFORMATION FROM HIGHLY EXPERIENCED DRIVERS --- WHO MUST REGULARLY CONTEND WITH NYC'S MYRIAD POTHOLES.

THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 39,001 AND THE CURRENT MILEAGE WAS UNKNOWN.

Mileage: 39,001

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING 35 MPH, THE CONTACT APPLIED THE BRAKES THEN THE PEDAL WENT TO THE FLOOR AND THE VEHICLE FAILED TO STOP. THE CONTACT PUMPED THE PEDAL AND EVENTUALLY THE VEHICLE STOPPED. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE CONTACT WAS INFORMED THAT THE BRAKES NEEDED TO BE REPLACED. SEVERAL DAYS LATER THE FAILURE RECURRED. THE VEHICLE WAS RETURNED TO THE DEALER AND THE CONTACT WAS INFORMED THAT THE MASTER CYLINDER AND THE BRAKE BOOSTER WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER HAD NOT BEEN NOTIFIED OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 144,000.

THE VEHICLE HAS A NASTY HABIT OF LOSING BRAKE PRESSURE OVER BUMPS. THIS CAN BE DUPLICATED EASILY AND IS A KNOWN ISSUE THAT TOYOTA HAS YET TO RECTIFY. SIMPLY DRIVE OVER A BUMP SUCH AS A BREAK IN CONCRETE ON A BRIDGE, POTHOLE, ETC. AND HOLD ON TIGHT. THIS CAN RESULT IN A CRASH AND SERIOUS INJURY AS OCCUPANTS EXPERIENCE A SUDDEN LOSS OF BRAKING FORCE WHICH CAN INDUCE PANIC AND COLLISION. *TR

IN THE PAST (STARTING AT 2,800 MILES) AND REPORTED NUMEROUS TIMES TO THE DEALER (HUNTINGTON TOYOTA), TOYOTA CORPORATE AND THE NHTSA, WHENEVER THE CAR WENT OVER A ROUGH ROAD SERVICE WHILE BRAKING AT ABOUT 10 MILES AN HOUR THE REGENERATIVE BRAKING WOULD CUT OUT AND GIVE THE SENSATION OF THE CAR SURGING FORWARD REQUIRING MUCH GREATER BRAKING EFFORT TO BRING THE CAR TO A STOP. THE BRAKES WOULD RESET AFTER A FULL STOP AND THEY WOULD ACT NORMALLY UNTIL THE NEXT TIME BRAKING WAS DONE ON A ROUGH ROAD SURFACE. TOYOTA CLAIMED THAT THIS WAS NORMAL BEHAVIOR FOR THE PRIUS ABS SYSTEM, EVEN AFTER THE FIRMWARE UPGRADE WAS APPLIED. THIS TIME THE BRAKES DID NOT RESET AFTER A FULL STOP AND EVERY WARNING LIGHT ON THE DASHBOARD LIT UP. THERE WAS NO REGENERATIVE BRAKING AVAILABLE. THE CAR WAS BROUGHT TO THE DEALER WHO HAS HAD IT FOR MORE THAN A WEEK, AND IS REPLACING MAJOR BRAKE SYSTEM COMPONENTS UNDER MY EXTENDED WARRANTY. I WAS TOLD THAT WITHOUT THE WARRANTY THESE REPAIRS WOULD HAVE COST ME OVER $4500. THIS HAS BEEN AN ONGOING AND DANGEROUS SITUATION, WHICH MAY BE FINALLY RESOLVED AFTER ALL OF THE BRAKE COMPONENT REPLACEMENTS. AS AN ASIDE, THE BRAKE PADS SHOW SIGNIFICANT AND UNUSUAL WEAR BECAUSE THE REGENERATIVE BRAKING DID NOT WORK AS IT SHOULD. *TR

BRAKES FAILED WHILE DRIVING. PEDAL WENT TO THE FLOOR. VERY LITTLE BRAKING POWER LEFT. LUCKILY I DIDN'T HAVE TO STOP SUDDENLY AND WAS ABLE TO BRING THE CAR TO A STOP SLOWLY. HAD THE CAR TOWED TO TOYOTA DEALER WHERE THEY DIAGNOSED THE PROBLEM AS THE BRAKE BOOSTER / MASTER CYLINDER. THEY TOLD ME THERE WAS AIR IN THE BRAKE SYSTEM. I RECEIVED A QUOTE FOR ALMOST $2900 TO FIX THE BRAKES. I CALLED TOYOTA CORPORATE OFFICE AND ASKED FOR ASSISTANCE WITH THIS CATASTROPHIC BRAKE FAILURE BUT WAS REFUSED. SEARCHING ONLINE FOUND OTHERS WITH SAME FAILURE. IN PARTICULAR, THERE WAS A PERSON WITH 43K MILES WITH EXACT SAME ISSUE, AND TOYOTA REFUSED TO HELP HIM. THIS IS A VERY DANGEROUS FAILURE AND SHOULD BE A RECALL. PLEASE INVESTIGATE FULLY AND FEEL FREE TO CONTACT ME FOR ANY ASSISTANCE. I AM IN THE PROCESS OF REPLACING THE BRAKE BOOSTER BUT I WILL KEEP THE OLD ONE IN CASE YOU NEED IT FOR YOUR INVESTIGATION. I HAD SIMILAR ISSUE ON MY 2004 LEXUS RX330 AND THERE WAS EVENTUALLY A RECALL FOR IT. IT IS UNACCEPTABLE FOR A 3 YEAR OLD CAR TO HAVE THIS KIND OF A SAFETY FAILURE. MY WIFE AND KIDS COULD HAVE BEEN SERIOUSLY HURT OR KILLED. *TR

FIRST INCIDENT: APRIL 15, 2013 I LOST MY BRAKES WHILE I WAS DRIVING HOME FROM MY NIGHT SHIFT WORK AS A REGISTERED NURSE. I WAS AT AN INTERSECTION TWO BLOCKS FROM MY HOUSE WHEN I FELT THE BRAKE WAS FAILING. IT WAS A GOOD THING THAT I WAS DRIVING SLOW TO MAKE A TURN WHEN I FELT THE BRAKE SYSTEM WAS NOT WORKING. I WAS ABLE TO STEER IT TO A PARKING LOT NEARBY BY USING THE FOOT BRAKE. PRIOR TO THIS INCIDENT, I HEARD SQUEAKING NOISES FOR ABOUT THREE DAYS WHENEVER I STEP ON THE BRAKES. I WAS RELIEVED THAT I DID NOT GET INTO AN ACCIDENT. ACTION AFTER THE 1ST INCIDENT: APRIL 24, 2010. WE TOWED THE CAR TO DCH TOYOTA FREEHOLD, AND IT TOOK ABOUT 5 DAYS TO REPAIR THE BRAKES SO THEY GAVE US A LOANER CAR WHICH WE TRULY APPRECIATE. BUT WHEN WE PICKED UP THE CAR, THE BRAKES WERE FIXED BUT THE SQUEAKING NOISE IS STILL PRESENT, AND OUR WINDSHIELD WAS CRACKED. WE CALLED THE DEALERSHIP RIGHT AWAY TO INFORM THEM ABOUT THE SQUEAKING NOISE AND TO COMPLAIN ABOUT THE CRACKED WINDSHIELD. I WAS TOLD BY THE SERVICE REPRESENTATIVE THAT THEIR TECHNICIANS TESTED MY CAR AND DEEMED IT SAFE TO DRIVE AND THAT THEY WOULD NEVER RELEASE MY CAR UNLESS THEY KNOW IT IS SAFE TO BE ON THE ROAD. SECOND INCIDENT: APRIL 29, 2013, I LOST THE BRAKES AGAIN WHILE I WAS ON MY WAY TO WORK AROUND 7:00 PM. I REALLY GOT VERY SCARED BECAUSE THERE WAS SO MUCH TRAFFIC AT THAT TIME. I WAS ABLE TO STOP AND PARK MY CAR SLOWLY TO THE CURB WITHOUT HITTING ANYBODY ELSE BY USING THE FOOT BREAK. ACTION AFTER THE SECOND INCIDENT: SAME NIGHT, WE TOWED THE CAR BACK TO THE DEALERSHIP FOR REPAIR, AND AFTER A WEEK OF WAITING, THEY FINALLY CAME BACK TO US SPECIFYING THAT THE WHOLE MASTER CYLINDER AND BRAKE PAD ASSEMBLY IS DEFECTIVE AND NEEDS TO BE REPLACED AND WILL COST MORE THAN 4K FOR PARTS ALONE. CONTACTED TOYOTA ABOUT THIS ISSUE, AND THEY SAID THAT THEY WILL NOT ASSIST US, SINCE WE EXCEEDED THE WARRANTY PERIOD. *TR

ON 01 MAY 2013, I WAS DRIVING MY TWO DAUGHTERS HOME FROM SCHOOL AND THE BRAKES ON MY 2010 TOYOTA PRIUS FAILED. THE BRAKE PEDAL BECAME VERY STIFF AND THE BRAKES DID NOT RESPOND. I BEGAN TO PANIC BECAUSE WE WERE TRAVELING DOWN A STEEP HILL. I CONTINUED TO PUMP THE BRAKES AND SUDDENLY, THE PEDAL GAVE WAY AND THE CAR CAME TO A SCREECHING HALT. I WAS LUCKILY WITHIN WALKING DISTANCE OF MY HOUSE. I HAD MY CAR TOWED TO THE DEALERSHIP AND THEY INFORMED ME THAT MY BRAKE BOOSTER AND MASTER CYLINDER NEEDED REPLACEMENT AT A COST OF $5500. I'M SHOCKED. MY CAR IS 3 YEARS OLD. AFTER RESEARCH, I DISCOVERED THIS IS A COMMON PROBLEM FOR THE 2010 PRIUS. WHAT I FIND MOST DISTURBING IS THIS IS CLEARLY A MANUFACTURER'S DEFECT, THAT IS AN EXTREMELY DANGEROUS SAFETY HAZARD. PRIOR TO OWNING MY PRIUS, I WAS A LOYAL TOYOTA BUYER. I HAVE HAD CONSISTENT ACCELERATION ISSUES WITH MY BRAKES, EVEN AFTER THE RECALL. IF TOYOTA DOES NOT ADDRESS THIS ISSUE, I DON'T INTEND TO PURCHASE ANOTHER TOYOTA PRODUCT. *TR

WHILE I WAS BRAKING TO STOP AT THE RED LIGHT, THE CAR ACCELERATED. I MOVED THE STEERING WHEEL TO HIT THE CURB TO PREVENT CROSSING THE RED LIGHT. IT HAPPENED TO ME COUPLE OF TIMES. THEN I REALIZE IT HAPPENS ONLY WHEN I AM DRIVING OVER UNEVEN SURFACE OR OVER BUMPS. IT IS REALLY SCARY. I ALMOST HIT A CAR SEATTLE DOWNTOWN GOING DOWN THE HIT BECAUSE MY CAR ACCELERATED INSTEAD OF STOPPING. I TOOK IT THE CAR DEALER BUT THEY SAID THERE IS NO PROBLEM.

I WAS DRIVING TO WORK THIS MORNING AND A MAN STEPPED OFF THE CURB RIGHT IN FRONT OF ME (NOT IN A CROSSWALK). I HIT MY BRAKES, AND HIT A POTHOLE IN THE ROAD AT THE SAME TIME. THE CAR ACCELERATED AND FELT AS IF IT WAS SHUDDERING, IT WAS NOT BRAKING AT ALL EVEN THOUGH I MASHED THE PEDAL TO THE FLOOR. I WAS FORCED TO SWERVE TO MISS THE MAN, WHICH I THANKFULLY DID. AFTER THAT I GOT MOVING AGAIN I APPLIED THE BRAKES AND THEY WORKED FINE. WHEN I ARRIVED AT WORK I TRIED IT AGAIN BY FINDING SOME POTHOLES IN THE PARKING LOT. @ 15 MPH THE PROBLEM OCCURRED AGAIN ONLY WHEN I WAS HITTING THE POTHOLES WHILE APPLYING THE BRAKES. I WENT TO TOYOTA.COM AND FOUND THIS HAS BEEN AN ISSUE SINCE FEB 2010. I PURCHASED MY CAR IN NOV 2010; I THEN CALLED MY SERVICE DEALER AND TALKED TO THE SERVICE MANAGER WHO CLAIMED TO HAVE NEVER HEARD OF THAT PROBLEM EVEN THOUGH I TOLD HIM I FOUND THE INFO AT THE PRESSROOM.TOYOTA.COM WEBSITE. HE THEN PROCEEDED TO LET ME KNOW I SHOULD NOT BELIEVE EVERYTHING I READ IN THE INTERNET AND OFFERED TO LET ME BRING IT IN AND HE WILL LOOK AT IT. I AM LEAVING WORK EARLY TODAY TO HAVE IT LOOKED AT. *TR

IN THE MORNING I STARTED MY CAR AND THE ABS LIGHT AND WARNING LIGHTS CAME ON AND STARTED BEEPING. I REVERSED MY CAR SLIGHTLY TO CHECK THE BRAKES AND NOTICED MY BRAKES WERE NOT BEING RESPONSIVE. I PUT THE VEHICLE INTO PARK AND CALLED THE WONDRIES TOYOTA DEALERSHIP AND TOLD THEM MY BRAKES WERE NOT FUNCTIONING PROPERLY AND MY ABS WARNING LIGHT WAS ON. DESPITE MY HAVING INFORMED THEM OF MY BRAKE FAILURE, THEY TOLD ME TO BRING THE CAR INTO THE DEALERSHIP. I REVERSED OUT OF MY GARAGE, SHIFTED THE CAR INTO DRIVE, AND PROCEEDED DOWN THE HILL WITH CAUTION. I DID NOT PRESS ON THE ACCELERATOR. MY CAR BEGAN TO ACCELERATE DOWN THE HILL DUE TO GRAVITY AND REACHED A SPEED OF APPROXIMATELY 15 MPH, AT WHICH TIME I PUMPED THE BRAKE PEDAL BUT THE CAR WOULD NOT STOP OR SLOW DOWN, AND IT CONTINUED MOVING DOWN THE HILL. AT THE BOTTOM OF THE HILL, AFTER TRAVELING APPROXIMATELY 1/4 OF A MILE, I TURNED RIGHT INTO A SMALL STREET WITH A SLIGHT INCLINE IN ORDER TO STOP THE MOMENTUM. MY CAR SLOWED AND I PUT ON THE EMERGENCY BRAKE AND PUT THE CAR INTO PARK. I CALLED MY BROTHER FOR HELP. WHEN HE ARRIVED, I TURNED THE CAR ON TO SHOW HIM THE FLASHING ABS WARNING. IT FLASHED FOR ABOUT ANOTHER 15 SECONDS BEFORE SUDDENLY STOPPING. MY BRAKES THEN BEGAN FUNCTIONING AGAIN THOUGH THEY FELT SPONGY WHEN I PRESSED DOWN ON IT. I TURNED ON MY EMERGENCY LIGHTS AND DROVE SLOWLY TO THE DEALERSHIP. I PARKED THE CAR AND TURNED OFF THE ENGINE. WHEN A REPRESENTATIVE CAME BY, I TURNED ON THE CAR AND SHE PRESSED DOWN ON THE BRAKE TO FEEL THEM. THE ABS LIGHTS SUDDENLY CAME ON AGAIN AND SHE SAID THE BRAKE PRESSURE DID NOT FEEL RIGHT AND THERE WAS SOMETHING DEFINITELY WRONG WITH MY BRAKES. AFTER IT WAS ASSESSED I WAS INFORMED I NEEDED A NEW ABS ACTUATOR ASSEMBLY AND AN ACCUMULATOR PUMP FOR THE MASTER CYLINDER. TOTAL COST WAS ESTIMATED AS $4600. *TR

I WAS DRIVING MY 2010 PRIUS IN A CONGESTED AREA AND CARS IN FRONT OF ME STOPPED SUDDENLY. AS I BRAKED HARD, THE CAR SEEMED TO LURCH FORWARD FOR ABOUT ONE SECOND, MAYBE LONGER, AND THEN THE BRAKES KICKED IN. I NOTICED THAT THE ROAD WAS ROUGH. THE SURFACE WAS DRY. FORTUNATELY, I HAD ALLOWED AMPLE DISTANCE FROM THE CAR IN FRONT OF ME, AND THERE WAS NO COLLISION, BUT IT WAS VERY UNSETTLING. IN THE PREVIOUS MONTH, I HAD THREE OR FOUR LESS INTENSE SENSATIONS OF "LURCHING FORWARD," WHICH OCCURRED WHEN I STOPPED AT A PARTICULAR INTERSECTION WHEN I HAD JUST STARTED THE CAR, BUT THE ROAD WAS SMOOTH. *TR

I HAD BEEN HEARING A LOT OF GRINDING NOISES THAT JUST GOT WORSE. WHEN I WENT TO THE DEALER, THEY DISCOVERED THAT MY BRAKE PADS HAD FAILED/FROZEN. THEY REPLACED MY PADS AND MACHINED MY ROTORS. THEY COULD NOT EXPLAIN WHY A CAR I HAD FOR ONLY A LITTLE OVER A YEAR HAD THIS PROBLEM. THEY AT FIRST BLAMED MY DRIVING, AND THEN THE ROADS (I.E. TOO MANY GRAVEL ROADS). NOW, AT 68,300 MILES THOSE PADS HAVE NOW FAILED AGAIN. ONE IS COMPLETELY WORN DOWN AND THE ROTOR IS NOW RUSTED THROUGH. NO ONE CAN EXPLAIN WHY THIS IS HAPPENING. WHEN I DEMANDED AN ANSWER, THEY TOLD ME THAT A "BULLETIN" HAD GONE OUT TO THE DEALERS ONLY STATING THAT DUE TO THE PADS FAILING, THEY WERE "REDESIGNING" THEM. BUT, THEY WOULD ONLY REPLACE FOR FREE THOSE THAT FELL UNDER THE 36,000 MILE WARRANTY. I DON'T UNDERSTAND WHY, IN LESS THAN 69,000 MILES I HAVE HAD TO HAVE THIS REPAIR DONE NOT ONCE, BUT TWICE. THEY TELL ME NO OTHER OWNER HAS HAD THIS PROBLEM, BUT I FIND THAT HARD TO BELIEVE. CAN ANYONE TELL ME IF THERE ARE OTHER COMPLAINTS OF THIS TYPE, AND WHAT CAN BE DONE TO RECTIFY THIS PROBLEM. *TR

DEALER INSIST IT IS ONE ASSEMBLY AND ESTIMATES REPLACEMENT TO BE $5,166 ($1,638 FOR BOOSTER AND $2,466 FOR MASTER CYLINDER). DUE TO THE COMPLETE WARNINGLESS FAILURE OF BRAKES WHILE IN OPERATION IT WOULD SEEM TO A CRITICAL SAFETY HAZARD DUE TO THE DESIGN FLAW IN THE COMBINED BRAKE BOOSTER AND MASTER CYLINDER BRAKE ASSEMBLY CAUSING A BRAKE FAILURE IN OPERATION. *TR

ON MULTIPLE OCCASIONS, I HAVE EXPERIENCED ISSUES WITH THE CAR SUDDENLY ACCELERATING WHILE I'M PRESSING THE BRAKES. SPECIFICALLY, THIS APPEARS TO OCCUR WHEN BRAKING ON UNEVEN SURFACES (IE CONSTRUCTION AREAS, POT HOLES, ETC.). THIS CAN OBVIOUSLY BECOME A DEADLY SITUATION IF ONE IS TRYING TO STOP THE VEHICLE AND WITH THIS PROBLEM RUN INTO THE CAR/VEHICLE AHEAD. MOST RECENTLY THIS OCCURRED ON THE SURFACE STREETS IN LOW SPEED, IN TRAFFIC. IT FEELS LIKE THE CAR LURCHES AHEAD WHILE APPLYING THE BRAKE.

MY PRIUS IV, PURCHASED NEW IN 2010, INTERMITTENTLY HAD A LUNGING FORWARD PROBLEM WHEN GOING OVER SPEED BUMPS, POT HOLES ETC. I WOULD HAVE TO STOP IT BY BRAKING QUICKLY, SO I DIDN'T COLLIDE WITH A CAR AHEAD. I INFORMED TOYOTA OF THIS PROBLEM WITHIN THE FIRST YEAR. THEY TESTED IT AND SAID THEY COULD FIND NOTHING. I MENTIONED THIS TO THEM ON VARIOUS OCCASIONS WHEN I TOOK THE CAR FOR ITS PERIODIC MAINTENANCE OF 5000 MILE INTERVALS. ON DECEMBER 26, 2012 I WAS STOPPED WAITING TO GO LEFT WHEN I WAS REAR-ENDED. I WENT TO PULL OVER TO THE SIDE OF THE ROAD TO ASSESS THE DAMAGE. WHEN I ACCELERATED TO GET TO THE SIDE OF THE ROAD,THE CAR TOOK OFF CRAZILY, AT A HIGH RATE OF SPEED FOR ABOUT 6-7 SECONDS, ZIGZAGGING UNCONTROLLABLY ON THE 2 LANE ROAD. IF THERE WERE CARS COMING TOWARD ME, I WOULD HAVE BEEN IN A HEAD ON CRASH. I IMMEDIATELY CALLED TOYOTA SERVICE OF SCRANTON,PA AND ASKED THEM TO SEE AND ASSESS THE CAR'S PROBLEM. THEY MADE AN APPOINTMENT AND CONCLUDED.SAID THERE IS NO PROBLEM INTERNALLY, AND SUGGESTED REMOVING THE AFTER MARKET FLOORMAT. I THEN PROCEEDED TO SHOW THEM THE SAME PROBLEMS MANY CUSTOMERS ARE HAVING WITH THE PRIUS , INCLUDING AN ARTICLE BY STEVE WOZNIAK, THE CO-FOUNDER OF APPLE COMPANY, WHO HAD ACCELERATION PROBLEMS WITH HIS 2010 PRIUS. I CALLED THE MAIN TOYOTA HEADQUARTERS LATER, EXPLAINING THE PROBLEM AND THEY TOO SAID THERE IS NO MALFUNCTION , ONLY MENTIONING THE FLOOR MATS AGAIN.. THIS IS NOT THE CASE AS THE CAR HAS HAD ACCELERATION PROBLEMS FROM THE BEGINNING AND TO FURTHER CLARIFY, I WAS ABLE TO FINALLY STOP THE CAR... THE MAT WAS NO WHERE NEAR THE ACCELERATOR. I AM AFRAID TO DRIVE THIS FOR OTHERS' SAFETY, MY PASSENGERS AND MY OWN SAFETY. I TAKE CARE OF MY CARS FAITHFULLY. YOU CAN VIEW MY RECORDS.

OK, THIS TYPE OF INCIDENT (LOSS OF BRAKING AT LOW SPEEDS) HAS HAPPENED REPEATEDLY IN THIS VEHICLE, DESPITE A RECALL IN 2010 AND "SOFTWARE FIX". THE DATE LISTED IS APPROXIMATE. I FELT COMPELLED TO PROVIDE THIS INFORMATION AFTER HAVING THIS HAPPEN TWICE IN THE PAST WEEK, IN THE HOPES THAT SOME PERMANENT FIX CAN BE MADE AVAILABLE, AND TO WARN PROSPECTIVE BUYERS TO BE CAUTIOUS. IN ALL INCIDENTS, WHEN TRAVELING OVER BUMPS IN A ROAD WITH THE BRAKES ENGAGED, THERE IS A SUDDEN SLIGHT "ACCELERATION", BUT IN ACTUALITY, PROBABLY JUST THE MOMENTARY LOSS OF BRAKING. THIS HAPPENS WHEN GOING OVER: (1) MANHOLE COVERS (2) POTHOLES (3) SLIGHT DIPS IN THE ROAD (FROM SUBSIDING ROAD PATCHING AREAS). DOES NOT APPEAR TO BE WORSE IN WET CONDITIONS, AND HAS ONLY HAPPENED TO ME AT LOW SPEEDS (~5 -- ~ 20 MPH). NOTE THAT ORIGINAL CARPETED MATS WERE REPLACED WITH ONES THAT FIT A BIT BETTER, AND DO NOT CAUSE ANY ISSUES WITH THE ACCELERATION PEDAL. ONCE THE BUMP IS PASSED OVER, NORMAL BRAKING OCCURS. WHEN I FEEL THIS VEHICLE MOMENTARILY LOSE BRAKING, I QUICKLY LET OFF THE BRAKE FOR A SPLIT SECOND, AND RESUME BRAKING. I HAVE GOTTEN USED TO THIS DEFECT, BUT I SURE WOULD LIKE SOMEONE TO INVESTIGATE AND PROVIDE A QUALITY RECALL FIX. THIS BRAKING ISSUE HAS HAPPENED IN NORTH CAROLINA (WHERE THE VEHICLE WAS PURCHASED) AND IN MASSACHUSETTS. THANK YOU. *TR

WHEN I ENCOUNTER A BUMP WHILE APPLYING THE BRAKES IN MY 2010 TOYOTA PRIUS, THE BRAKES FULLY DISENGAGE MOMENTARILY. THIS CAUSES THE CAR TO JOLT FORWARD UNEXPECTEDLY. MY FOOT IS NOT COMING OFF THE BRAKE AT ALL WHEN THIS HAPPENS, SO I KNOW I AM NOT THE CAUSE OF IT. I RECEIVED A RECALL NOTICE BY MAIL IN FEBRUARY 2010 TO ADDRESS JUST THIS ISSUE. I TOOK THE CAR TO THE NEAREST TOYOTA DEALERSHIP TO HAVE THE RECALL WORK COMPLETED. IT WAS INTENDED TO FIX THE MALFUNCTION IN THE ANTI-LOCK BRAKE SYSTEM THAT CAUSED THE BRAKES TO DISENGAGE WHEN THE CAR HITS A BUMP. THE RECALL WORK WAS COMPLETED, BUT THE PROBLEM WAS NOT RESOLVED. THE BRAKES STILL DO THE EXACT SAME THING AND FULLY DISENGAGE WHEN I HIT A BUMP WHILE BRAKING. THIS IS UNQUESTIONABLY DANGEROUS AND A SERIOUS SAFETY HAZARD. *TR

THE UNINTENDED ACCELERATION ACCIDENT HAPPENED ON 7/18/2012, ~6:20 PM AT COMPANY'S PARKING LOT. I BACKED MY 2010 PRIUS SLOWLY. THEN I SAW A CAR COMING ON MY WAY. BUT BEFORE I TOOK ANY ACTION, THIS PRIUS SUDDENLY STARTED ACCELERATING, IT WENT WILDLY, AND TURNED MORE THAN 360 DEGREE BACKWARD IN THE PARKING LOT IN JUST A FEW SECONDS. SINCE THE CAR PARKED BETWEEN A BUILDING AND A SLOP, FROM THE FRONT MIRROR, FIRST, I SAW THE BUILDING WALL AND GLASSES, THEN I SAW THE SLOPE, THEN I SAW A CAR PARKED CLOSE TO MY CAR: NO! DON'T HIT THAT CAR! THAT IS THE LAST THING I REMEMBER. BECAUSE OF THE FAST TURNING OF THE CAR AND BECAUSE I WAS SO TERRIBLY SCARED, I LOST CONSCIOUS AFTER THAT UNTIL THE PRIUS HIT THE TRUCK AND BOUNCED BACK AND STOPPED BY ITSELF. AFTER A FEW SECONDS, I WOKE UP AND REALIZED: I AM STILL ALIVE. I GOT OFF THE CAR AND SAW PRIUS PASSED THE TWO CURBS AND HIT THE TRUCK. THE TWO TIRES ON THE DRIVER SIDE GOT FLAT BECAUSE THEY PASSED THE CURB VERY FAST. I WAS SO SCARED THAT I COULDN'T RECALL OF ANYTHING FOR A FEW DAYS UNTIL WEEKEND. WHY DID THE CAR LOSE CONTROL? ONE MAY ARGUE THAT I STEPPED ON THE ACCELERATOR. THIS COULD HAPPEN TO NEW DRIVERS, BUT NOT TO ME BECAUSE I HAVE BEEN DRIVING FOR SO MANY YEARS AND ALWAYS A GOOD DRIVER. MANY TIMES I SAW A CAR ON MY WAY WHEN I WAS BACKING, I ALWAYS STOPPED RIGHT AWAY. AND I WAS HEALTHY IN A NORMAL DAY IN NORMAL MODE, ALERT AS USUAL. WHY WOULD I STEP ON ACCELERATOR WHEN BACKING? EVEN IF I MIS-STEPPED ON THE ACCELERATOR, I CAN ALWAYS SWITCH TO BRAKE RIGHT AWAY. BUT I COULD?T DO ANYTHING ABOUT THE CAR ON THE DAY. IT WAS OUT OF CONTROL COMPLETELY. AFTER I LOST CONSCIOUS, MY HANDS WERE OFF THE STEERING WHEEL AND MY FOOT DIDN'T STEP ON ANYTHING, THE CAR DIDN'T SLOW DOWN BUT STILL MOVED FAST AND PASSED TWO CURBS EASILY. SUCH A MANIPULATION CAN ONLY BE DONE WHEN THE CAR IS IN ACCELERATION, AND BY ITSELF. PLEASE INVESTIGATE IT ASAP! *TR

2010 PRIUS BRAKE FAILURE. I WAS ABLE TO SLOW DOWN THE CAR BY REPEATED PUMPING ON THE BRAKES. FORTUNATELY, MANAGED TO CRAWL TO A NEARBY TOYOTA DEALER BY USING THE PUMPING TECHNIQUE AND HAVE MY FOOT ON THE EMERGENCY FOOT BRAKE JUST IN CASE. TOYOTA SAID I NEED TO REPLACE THE MASTER CYLINDER WITH ACTUATOR. TOTAL COST PARTS/LABOR $4100. I AM UPSET BECAUSE MY FAMILY OR OTHERS COULD HAVE BEEN SERIOUSLY HURT IF I PANICKED AND NOT PUMPED ON THE BRAKE TO SLOW THE VEHICLE DOWN. THIS IS A SERIOUS HAZARD WHICH SHOULD BE KNOWN AS I HAVE SEEN OTHER SIMILAR COMPLAINS LODGE ONLINE. *TR

I APPLIED MY BRAKES APPROACHING A TRAFFIC LIGHT AND HIT A SMALL POT HOLE AND THE ENTIRE VEHICLE JERKED FORWARD EVEN THOUGH THE BRAKES WERE APPLIED AND NEVER TAKEN OFF THE PEDAL. I HAD TO THEN PRESS DOWN HARDER ON THE BRAKE PEDAL TO COME TO A COMPLETE STOP. I HAVE OBSERVED THIS TYPE OF BEHAVIOR WHEN THE ROAD CHANGES SURFACES AND IS LOWER THAN THE PREVIOUS SURFACE AND DIPS IN THE ROAD. THIS IS ALL OBSERVED WHILE ONLY BRAKING AT LOW SPEEDS LESS THAN 40 MPH. EVERY TIME THIS BEHAVIOR IS OBSERVED THERE IS A LOUD BANG, I AM NOT COMPLETELY SURE IF THIS IS FROM SWITCHING SURFACES OR HIT POT HOLES OR DIPS IN THE ROAD. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 40 MPH, THE CONTACT WAS ABLE TO ABNORMALLY DEPRESS THE BRAKE PEDAL INTO THE FLOORBOARD. THE ABS WARNING, TRACTION CONTROL WARNING AND THE EMERGENCY BRAKE WARNING LIGHTS ILLUMINATED ON THE INSTRUMENT PANEL. AFTER CONTINUALLY DEPRESSING THE BRAKE PEDAL, THE VEHICLE CAME TO A STOP. THE FAILURE RECURRED FOUR DIFFERENT TIMES. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN ADVISED THE CONTACT THAT THE BRAKE POWER BOOSTER WOULD HAVE TO BE REPLACED BUT DID NOT GUARANTEE THAT THE BOOSTER WAS THE ACTUAL CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 55,000.
