2012 Toyota Prius Complaint Log

I am writing to bring attention to a critical safety issue affecting the 2012 Toyota Prius and other Toyota models equipped with the brake booster and actuator system. These components are failing at alarming rates, leaving vehicles with no functional brakes, ABS, or traction control. Additionally, this failure compromises the hybrid system due to the regenerative braking no longer working, potentially causing further damage to hybrid components and resulting in repairs costing several thousand dollars. Toyota issued Customer Support Program ZJB, which covered these issues for a limited period. This program was in effect from August 31, 2021, with no mileage or year restrictions, but offered secondary coverage for up to 10 years or 150,000 miles from the vehicle’s first use. Unfortunately, my vehicle, with approximately 130,000 miles and 12 years of age, was denied coverage when brought to a dealer after the program had ended. Despite the brake booster and actuator failing, the dealership did not advise me not to drive the vehicle, further emphasizing the gravity of this oversight. This is a significant safety hazard, as vehicles with these failures lack the ability to stop effectively, risking lives on the road. Furthermore, this problem is not isolated to my Prius; it affects thousands of Toyota vehicles equipped with these components. The estimated repair cost exceeds $3,000, an undue burden on owners for an issue that stems from defective manufacturing. I firmly believe Toyota’s decision to address this problem through a limited Customer Support Program, rather than a full recall, is inadequate and irresponsible. This issue meets the criteria for a safety recall and should be treated as such by the National Highway Traffic Safety Administration (NHTSA). I respectfully urge the NHTSA to investigate this matter further asap/mandate a recall for all affected vehicles. This is a big safety issue.

TCS, ABS, Check Engine, and Warning lights all came on at once. Brake pressure immediately decreased. After the following diagnosis, Toyota said the brakes will continue to worsen and fail completely. Error codes C1249 and C1391 were presented. Toyota dealership diagnosed a leak within the brake pump actuator and said these parts needed replaced: 04009-79147 Brake cylinder kit 04006-22212 Brake pump assembly

I have a 2012 Prius V with just under 65k miles. This morning I woke up to go to work, drove about 5 minutes down the road when suddenly the ABS, PCS, brake and traction control lights illuminated. My brakes felt much more stiff, the car took longer to brake, and I had to depress the brake pedal down much further than normal to get any braking response at all. I quickly scheduled an appointment to bring my vehicle to my local Toyota dealership for inspection. I was told by the service department that it will cost me $4.5K to replace the ABS actuator pump (47070-12020) and brake booster & master cylinder (47050-47110) because the system malfunctioned/failed. I was in shock! I quickly ask if Toyota had an open recall for the ABS brake malfunction/failure issue and was told no. That answer did not sit well with me because this is a serious problem. Plus, this should not happen to a vehicle with under 65K miles. I've owned several Toyota vehicles in the past and I’ve never had anything like this happen to me. Today, I searched “2012 Prius ABS Brake Issue” online, and found multiple stories similar to mine on blogs, posting, etc... about the Toyota Prius ABS brake problem. I even heard that Toyota had a program in place to address this issue but it expired in 2019. Vehicle owners had to fight to bring the issue to Toyota's attention in order to get their vehicle repaired before the end of the program. Can you tell me why the NHTSA haven't forced Toyota to issue a mandatory recall to address this serious and know safety issue? Toyota knows about this issue and should be held accountable to fix the problem. I don’t want anyone to lose their life due to this known issue. Please help force Toyota to keep the road safe for all of us. Thanks, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I took my vehicle in to the Toyota dealership last month because of a brake related noise that was concerning and a loss of brake sensitivity. The diagnostic showed that the brake booster was showing signs that is would fail soon. I was informed that there was a warranty program (ZJB) for it but the warranty required that a specific error code must be present (C1391), regardless of the obvious symptoms. They were unwilling to honor the no cost replacement even though everything but the error code was present. Fast forward to just under a month after the warranty period expired (16 APR 2022 was the expiration date, today is 13 MAY 2022) and the vehicles brakes nearly fail and the error code, which was required for the warranty replacement is now present. Toyota is unwilling to assist me in the slightest with the cost regardless of the inspection prior to expiration of the warranty showing that is was approaching failure and the error code showing shortly after expiration of the warranty. I never received a notice that there was even a warranty for the part in the first place, I was only informed when it took it in the first time, before the warranty expired.

MY brake warning lights have coming on for over 12,000 miles abs , vehicle stability off/ stability control and indicator and red brake light .Last week they came on and stay on .I took it to mechanic he told me there was a recall on them up to 150,000 miles .I don't see it on your site .The part is Toyota Brake Booster part Number - 47050-47180. I mention this to toyota in January and they said the light sometime just come on .I don,t know what the mileage should have anything to do about a recall

THIS CAR HAS A STEERING WHEEL PROBLEM

The front windshield wiper no longer performs on high but does perform on the lower settings. We experienced very heavy rain yesterday for the first time in a while and needed the high setting to adequately visualize the road and vehicles. It once switched to high the wipers were inoperable and had to be reduced in speed to even function. This is a significant safety concern as it drastically compromises your visibility in heavy rain conditions, such as those we experienced. Yes it is available for inspection upon request.

The vehicle was traveling on the interstate at cruising speeds around 70 MPH when the braking system suddenly lost nearly all function. The dashboard began displaying multiple brake system warnings. There was no warning about potential failure. It was sudden and started when the brake pedal was not engaged. Some braking power remained, but it required full activation of the pedal. The vehicle was then driven very slowly to the next exit and later towed to the Toyota dealership for repair and inspection. The dealer has confirmed that this is the same error described in Toyota's Customer Support Program ZJB. Two adult passengers and one infant inside the vehicle and all other vehicles in the vicinity were at risk of suffering a high-speed crash.

Faulty brake and ECU assembly failure. A safety issue when driving. Was told by mechanic NOT to drive car as it could suddenly stop. Took car in 9/11/15 for software update for motor generator ECU and power management ECU as recall letter suggested. This is apparently common and needs to be corrected without cost to driver.

The contact's mother owns a 2012 Toyota Prius. The contact stated while driving at various speeds and depressing the brake pedal, the brakes made an abnormal sound. There were no warning lights illuminated. Additionally, the contact stated while the vehicle was parked, the ABS, the brakes, the electronic parking brake, and traction control system warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that the brake booster assembly, the brake booster pump, and the brake master cylinder needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist as an unknown Customer Satisfaction Program had expired. The failure mileage was approximately 125,000.

The contact owns a 2012 Toyota Prius. The contact stated that after starting the vehicle, the vehicle lost brakes and power steering functionality. The traction control, ABS, and braking system warning lights were illuminated. The vehicle was towed to the local dealer and was diagnosed with brake booster failure. The vehicle remained at the dealer and was not yet repaired. The manufacturer was notified of the failure. The contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes). The approximate failure mileage was 80,000.

The front and driver side air bags did not deploy (although the passenger side air bag did deploy). Initial impact came from behind, toward the passenger side, causing the vehicle to turn fully sideways, where the vehicle was then t-boned on the driver's side. The lack of driver side air bag deployment resulted in a lot of glass making it into the left side of the driver's head.

Brakes started making leaking sound when stopped at lights. Went to get diagnosed and was told I needed to have brake booster (toyota PN 47050-47180) and related pump assembly (Toyota PN 47070-47060) replaced. The specific cause note given by the technician: "FOUND BRAKE PUMP AND BOOSTER ASSEMBLY TO BE LEAKING INTERNALLY CAUSING PUMP TO ACUATE MORE THAN NORMAL WHICH WILL CAUSE THESE NOISES" Found out researching online that this is a common issue with the brake booster/master cylinder assembly affecting multiple models and model years of Toyota vehicles and a pending class-action lawsuit in Texas for it. Was told there was no recall but there was an extended service option. I was not made aware of this extended service option which they indicate in the program notes would be mailed to vehicle owners, and was told when the issue was diagnosed that my vehicle does not qualify for it.

Head gasket blow up at 175000 miles

The brakes are not working (ABS) I have to pamp brake

The contact owns a 2012 Toyota Prius. The contact stated that while starting the vehicle, the ABS, hybrid system, and traction control warning lights were illuminated. The dealer was made aware of the failure but informed the contact that the warranty was void due to a salvage title. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 102,000.

The brake booster started to make some noise every 5 seconds for about a week and one day when I was driving on the highway, all brake related warnings lights came on my dashboard. I want to brake and the brake did not hold correctly, once I touched it the car actually sped up then, I had to push hard to brake since that time the brake pedal is very hard to push and the car doesn't slow down at it should. I called Toyota many times for the extended warranty they had for this issue, but every time they apologize to me and they say it has expired. Although, I bought the car in March 2022 and the extended warranty expired on February 2022.( as they said). It is not fair that they have an extended warranty for brake booster for 10 years and when I get this same issue outside 10 years by one month, I'm not qualified. This is a safety issue and they are at fault. It should be for life to prevent disaster from happening and save innocent lives. Thank you. I have included some photos

a warning light came in on my dashboard brakes regarding the Brake pump accumulator. It feels like my brakes are not working right, not stopping like they always did.I was scared I almost hit someone in front of me at a red light because after applying the appropriate notes due on the brake pedal I noticed a delay in the car stopping. I had the brakes checked by a mechanic and they are ok. This is very dangerous. Can the manufacturer be required to repair this defect? Thank for your help.

on the pasenger side front low beam light if the headlight does not sit correctly it melts the headlight housing and or the headlight is dimmer my damage wiring harness in past dealership blames owner feel like this is a part defect the heat from a bulb should not melt or damage housing assemblies damage was found during a new headlight install

Bought the car from a dealership in january 2022 with 158,000 miles and heard buzzing noise that I was told was normal with hybrid cars.no codes showing on car and passed dealer inspection.Driving down a highway and heading to a stop brakes are hard to mash and caused skidding. No brake lights or abs lights are on. Couple days later brake lights and traction lights come on and then went back off. Take to Tires Plus and I am told I have to schedule appointment with toyota dealer as they do not have the software to diagnose. Take to toyota dealership to see codes 1391c for brake system. After searching issue there was a recall/customer warranty extension for replacement of this part for 150,000 miles /march 19,2022 whichever comes first. This did not show up on a report for dealer to inspect before selling vehicle and causes a huge safety concern to people that did not own this car before 150,000 miles. If a less experienced driver would not have known to reduce brake pressure applied it could have slid and caused collision or if brakes would have been needed during an emergency situation. Car is now sitting at toyota dealership and advised not to drive as brake pressure was lowered while being diagnosed. After talking with toyota they cannot provide assistance due to car being slightly over the 150,000 mile mark. Also if the brake pedal is mashed for an extended period of time the dash lights for brake system and traction control go off and will not come back on until it is driven for awhile

ABS dashboard light and loss of brake efficiency originally occurred on 2/23/22 and it has stayed lit every time vehicle is driven since then - and brake efficiency is affected since then. The ability to brake on demand is of paramount safety concern to the driver and passengers of our vehicle and also to those around our vehicle. The vehicle is available for inspection upon request. The vehicle was confirmed to have the same issue called out in the Toyota Customer Support Program (CSP) (https://static.nhtsa.gov/odi/tsbs/2020/MC-10181800-9999.pdf): replace Brake Booster and Brake Booster Pump Assemblies. The vehicle had some of the same DTC codes mentioned in the CSP and a few more. I have a photo from 2/24/22 proving ABS lights came on. This falls within the CSP by date (10 year from being put in service for this vehicle would be on 3/2/22) and just 3k over by miles. We are a loyal Toyota household - this is one of 3 Toyota vehicles we have owned (two Prius and Sienna) - and are in the market for an EV, and are excited about Toyota's new entry BZ4X in EV market. Toyota looking other way is an insult to brand loyalty and also violates the "spirit" of such CSPs (as opposed to Recalls, where I would have gotten this repair done timely before this failure happened). Also, equivalent CSP for a different Prius model (Prius C) (announced in May 2021 - 8 months after Prius V program was announced in Sep 2020) allows for the same Brake Booster and Brake Booster Pump Assembly issue to be covered up to Nov 30, 2022 and unlimited miles. How does it make sense that a 2012 Prius C owner experiencing the exact same problem on the exact same components on the exact same date would be covered while a 2012 Prius V owner would be denied the benefit? I would like NHTSA to work with Toyota to extend the CSP program officially to cover more vehicle owners like us and not live them stranded. That is not we expect from a company that prides in quality workmanship, customer-centricity.

I brought the car to the Toyota dealer already 3 times for the same problem,now happened again,they told me the first time,nothing wrong with the car,and I paid them,the second time nothing wrong they said,the third time they said it’s the 12 v battery has to be replace it,I did replace it,but still the same problem I have,the HYBRID SYSTEM problems ,the Toyota company should fix it ,because it’s something very unsafe it’s happening with my car,please help me to resolve this problem….. the car drive but stop anytime,I almost have a very bad accident with my daughter ON board

.The contact owns a 2012 Toyota Prius. The contact stated while driving 35 MPH, the ABS, brake lights, and traction control warning lights illuminated. The vehicle was taken to a dealer but was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle had exceeded the 150,000 warranty. The failure mileage was 152,900.

The contact owns a 2012 Toyota Prius. The contact stated while driving 60 MPH, there was an abnormal grinding sound coming from the brakes while the brake pedal was depressed. The brakes, the traction control, and the ABS warning lights were illuminated. The vehicle was then taken to an independent mechanic where it was diagnosed with brake booster and master cylinder assembly failure. The vehicle was not repaired for the most recent failure. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 106,019.

Hi, I have a 2012 Toyota Prius with around 120k miles that is completely inoperable. A local Toyota dealership is charging $3400 to replace both computers, but the more I research the more apparent it becomes that this is directly linked with past issues that were never fully resolved during previous recall attempts. The following article describes the exact situation my car is in (https://www.latimes.com/local/california/la-fi-prius-overheat-inverter-defect-20190414-story.html). When you combine that with the previous recalls back in 2014 & 2018, this quickly becomes a pattern. That pattern suggests that past software issues (1 & 2 below) were never fully resolved, and/or already caused premature damage to internal/computer components that then fail regardless. I spoke with the California Bureau of Automotive Repair who referred me to nhtsa. The agent I spoke with noted that because the Inverter wasn't actually replaced back in 2014 (Toyota only performed a software update), this part definitely could have been already damaged due to the software issues, which could then cause problems with the computers later on (which is what occurred). --- 1) NHTSA CAMPAIGN ID: 14V053000 - In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. 2) NHTSA CAMPAIGN ID: 18V684000 - Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven. --- General: - Computers both failed, not currently available for inspection as they are being replaced - If this computer failure happens again later (while on the road - as it has for other consumer), it's very dangerous as the car essentially shuts down on the spot - Dealer is dismissing this due to the car's age - No previous warning lights or messages

The Brake Booster pump assembly in the car has failed. Toyota issued a Customer Support Program to provide coverage for brake booster and brake booster pump assemblies, However, there are parameters limiting the age of the vehicle and mileage on the vehicle that exclude our car from the campaign. Therefore, the consumer is subject to pay for the entire cost of the repair, which can exceed $4,000. The malfunction occurs over time, and the part fails at a steady pace. Unfortunately, I was unaware of the issue until my ABS light came on, and the breaks became subject to malfunctioning. I took my car to the Toyota Dealership on January 29, 2022, and the dealership made no mention of the Safety Campaign which directly impacts my vehicle. In my opinion, Toyota has demonstrated negligence in regards to this issue. A full recall should be issued for this part. A Safety Campaign simply fails to completely resolve the issue at hand.

The contact owns a 2012 Toyota Prius. The contact stated that while driving at 30 MPH, the ABS, traction control, and several other unknown warning lights illuminated on the instrument panel as the brake pedal became spongy. The contact initially drove the vehicle to an independent mechanic who informed her of a service bulletin related to the failure; he then instructed her to take the vehicle to the dealer. The vehicle was taken to the dealer and the contact was informed that the vehicle could not be covered under a warranty related to the failure. The manufacturer was also notified of the failure and confirmed that her vehicle was no longer covered under warranty; a case was filed with the manufacturer. The contact agreed to have the vehicle repaired by the dealer and the vehicle remained in their possession. The vehicle had yet to be repaired. The failure mileage was approximately 192,000. The VIN was not available.

Loud noises coming from braking system. Diagnosed by Toyota service technician as a failure of the brake booster and booster pump assemblies. This specific issue is acknowledged by Toyota per a Customer Support Program ZJB. My vehicle, a 2012 Prius with 130,000 miles, qualifies for coverage under the CSP, however Toyota is denying coverage as the vehicle has not displayed a warning light or code associated with the problem, despite a Toyota service tech confirming the issue. Toyota wants me to drive a vehicle with brakes that may completely fail at any given moment. The Toyota Brand Engagement team has been no help in trying to get the repairs covered under the CSP. Class action lawsuits appear to be filed in several states as Toyota has refused to issue a full recall.

My 2012 Toyota Prius Hybrid: the brakes failed on 12/30/21 with virtually no warning which was very scary and could have caused fatalities and a crash. Luckily I was able to pull of the road and put on the e brake to stop the car but if the failure had happened about 10 mins earlier, I might have died because I was going 50 mpg coming down a large hill. I did some research and see that Toyota has KNOWN the brake booster assembly is bad on this model Prius yet they did not issue a full recall and are putting peoples' lives at risk! I am outraged, I was told by my local Toyota dealer that I could qualify for this "customer support program" but only after I had the break line (which also blew out) fixed so I spent $1,100 to fix the brake line then the booster/pump was still malfunctioning but then Toyota changed their tone and told me my vehicle has too many miles to qualify for the booster/pump replacement and then quoted me $4,500 to replace it !! This is an OUTRAGE, Toyota knows this is an issue but is skirting the issue and putting people in danger. It doesn't get much worse then brakes failing on a vehicle. I hope the government forces Toyota to do the right thing and slap them with a huge fine to teach them a lesson. This is not okay!

On 12/25/2021, I was driving in the country side under darkness and under heavy rain and I had a hard time seeing the road. There were no road lights so I could not make out where the divider, curve of the road or side of the road was. It was quite a safety hazards because cars were coming from the front, or a few inches off the road would be dirt field. I discovered that the headlamps of my 2012 Prius are full of water bubbles and the water bubbles are blocking and distorting the headlights. I have pictures and videos of the headlights. It is six days already and the water bubbles are still there, and it is not safe to drive out to the field at night or where there is no road lights, with such minimal and distorted lights. I found on the web that a few people experienced water bubbles in their headlamps over the years, but don't know if they reported to NHTSA. My car has no accident and no modification on the front of the car. Toyota representative and dealers said my car is out of warranty. There were no indications or symptoms of water bubbles in advance, until rain leaks into the headlamps. I did not notice if this happened in previous raining seasons, as I didn't drive out much at night.

The brake master cylinder/accumulator has failed causing multiple codes as well as dash lights for the brake and abs systems. I took the vehicle to the local Toyota dealership after reading about this problem in all other models of the Prius. I have just purchased the vehicle. They covered this issue with a free warranty replacement up until August of 2021. They had extended the warranty with restrictions until this next year. Reading about other models of the same car, the warranty still covers regardless of mileage. It's the identical part as other models that are still being covered. This is a $3000 dollar repair made in some vehicles for the identical part, but not in others. This is terrible customer service for an unsafe issue by Toyota. This issue does effect the braking in the vehicle and it is unsafe to drive. The regenerative braking also no longer is functioning changing the entire handling and characteristics of the vehicle.

The contact owns a 2012 Toyota Prius. The contact noticed that there was a significant amount of water on the floorboards from the windshield whenever it rained heavily. Additionally, the contact stated while at a traffic sign on a hill, the vehicle would roll backwards while in drive when she took her foot off the accelerator. The contact did not notice any warning lights. The contact also noticed that while parking the vehicle, whenever the PARK button on the dashboard was not depressed while the vehicle was running, the vehicle would roll forward. The contact took the vehicle to the local dealer, where it was not diagnosed and was not yet repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 80,000.

Vehicle has issue with brake booster and accumulator, making it dangerous to drive on the road as brakes would intermittently go out not allowing me to stop. Toyota Corporate had agreed to fix the vehicle originally based on good faith and acknowledgement of the defect under their "Customer Support Program" yet coerced me to go to the local dealership to get the repair, and now disclaims responsibility to cover the repair/parts costs. Toyota Corporate did call the dealer to authorize the repair on 12/14, but since then, have not paid for any of the repairs so my vehicle is being held hostage at the dealership.

Toyota did not inform us about a half recall on our family's Prius car. My wife driving yesterday with kids Christmas shopping and the brake pedal stopped working. She was able to thankfully to have space to let car slow down and pull off to side of road. People with a Toyota Prius need to know the brake pedal could stop working at any moment. The Toyota dealership says the repair is $2900 and they will not cover it. They advised I call Toyota so I did and spoke to 3 people advised and they said they would not. The half recall states online, which I dug and found after the dealership advisor told me about it, states that cars up until 8/31/2021 with unlimited milage are covered. After, then its 10 years from purchase and drops from unlimited milage to 150K. We are a few months from Sept and they would not make an exception and do the right thing. The cars is past the 150K milage BARELY, but still under 10 years. If the breaks had gone out in August 31st and a major accident happened would Toyota been liable? HAs this happened and people don't know? It's not right, not ethical, we were not informed of this at any point or even the last time I took the car into the dealership. The idea that others could have this happen to them or even get hurt out there is insane to imagine as a possibility actually a reality as it happened to us. Toyota headquarters brand representative (Monica supervisor) on phone told me that if my wife had the break pedal and system go out in August and died Toyota would have covered it. I almost dropped the phone. Others need to know about this. Do you know anyone with a Toyota Prius? or a Toyota? Please tell them the brake pedal could stop working at any moment and cause an accident. Please help us and together help others know about this. Toyota should have done the right thing, but they didn't. Toyota needs to alert others of this before someone gets hurt. The National Safety board needs to force to a full recall to REPLACE THEM

My brakes gave out while driving with my infant child luckily I was almost home and made it without hitting anyone or seriously hurting myself and my child. Had car diagnosed error code c1256. Local dealership won’t repair because I “missed “ recall and my car has salvage title. I cannot afford to fix on my own and I’m shaking as I drive with my child to work everyday praying to get there in one piece because I have to work…

I have a ABS alarm on my car. Toyota ABS C1391 (1/1) Current Abnormal Leak of ACC Press I tried to Talk to the Toyota I left a message with the service writer At Avondale Toyota In Arizona and left a message about my car problem They never returned a call to me! I have bought 4 new cars from Avondale Toyota. You would think they should return my call to talk about my cars brake problems I haven't received any return calls

ABS/Brake Actuators on these cars are faulty! Not able to apply adequate pressure on the brakes to stop the car confidently. Brake actuator hissing notating that pressure is being lost. Brakes feel like they are skipping, and also making a loud "quack/screeching" noise. Brakes were inspected on my vehicle, and the pads had over 60% life left, and no damage to the rotots, so its the brake actuator at fault. A very common issue on 3rd generation prius models, and a $3000+ repair through toyota. Customer support program ZJB issued. Its not a recall, but instead an "extended warranty". Toyota will not fix the problem without dash warning lights on, so my car is just waiting to break down or cause an accident. I worry about my life and the brakes failing at some point. Ive taken it to two different mechanics and they both noted its a well known problem that toyota is trying not to pay out for.

After feeling looseness from the front end all the way up to the steering wheel when going over any bumps I brought the car to the local dealer. After inspection I was told four things that are very disturbing: The steering shaft needs replacement; The cost will be more than $1100; There is no warranty or recall or cost coverage; The car is not reliable and should not be driven any more than essential until fixed (and they don’t know when the parts will be available). Although the car is out of warranty based on age, this car has only 66,525 miles after almost 9 years, and my wife and I have been the only drivers and not on any dirt roads. I have been told by an independent repair shop this is a known problem with Prius and should be a recall item since it is dangerous to keep driving. This is especially troubling since the dealer could not fix it when I was there because they have to order parts and they don't know when the parts will be in.

The contact owns a 2012 Toyota Prius V. The contact stated while driving at an undisclosed speed and making a stop, there was a rattling sound coming from the brakes while depressing the brake pedal. The vehicle was taken to the dealer for diagnostic testing. The contact was informed that the brake booster needed to be replaced. The vehicle was not repaired because there were no fault codes retrieved. The manufacturer was contacted and stated that the vehicle was out of warranty. The failure mileage was 100,000.

ABS Actuator and Booster Assembly failing. No recall was issued but a safety bulletin to the dealer with a cutoff date and nothing issued to consumer to know it needs to be replaced. Now I am outside their service bulleting window with a 3,000 repair that should be covered indefinitely by toyota

I was driving going 45mph when my car shut off and wouldn't start back up. It almost caused an accident from it stopping in the middle of the highway. The master warning light, brake system warning light, warning buzzer ABS warning light and the slip indicator light came on as also the message center reading to have the hybrid system checked immediately. I did have ot towed on for a diagnosis and it came back saying i needed a new inverter power module this will cost $2000 . i cant afford that. I read all over the internet how there is. Safety recalls. When i called toyota they said there are no recalls so now im stuck paying this. Not happy at all!!! If there are anymore 2012 prius with this problem please write a complaint so we can get this on recall and have the company cover the cost of repair.

I was Driving with my daughter as always,then the car put on the screen hybrid system problems and the car stop running…..I almost had an accident,I took the car to Toyota dealer and the charged me to fix it ,but the didn’t fix the problem,this is something that Toyota company should fix it before something bad happen while driving

My wife hit a deer at highway speed. The airbags deployed. The drivers side lower airbag deployed in the footwell. The driver was unable to get to the break paddle to stop due to the airbag at het feet. She had to use the emergency brake to stop the vehicle. That worked, but she had limited vision of the road ahead and it took some time for her to think of using the emergency brake.

I was driving with my 10 year old son on local city streets. I was approaching a busy intersection while going approximately 35 miles when my car just turned off with an error message about the hybrid system failing. I stopped the car and put it in park while trying to turn the car back on, but I kept getting the same hybrid system error message. While the stoplight was red, I got my son out of the car and over to the sidewalk because this was a dangerous situation where anyone not paying attention could've slammed into my stalled car (see picture of black Toyota Prius). I called AAA to get it towed. About 20 minutes later, a cop car pulled up to block my stalled car and then got it pushed to the side of the road (picture attached) because of how dangerous it was sitting there blocking traffic at a major intersection. My car was taken to Cabe Toyota dealership where they diagnosed it with a failed IPM card, which would cost around $4,000 to replace. I did a simple Google search and found that 80,000 Prius from 2012 - 2014 have been recalled for this EXACT reason. There have also been class action lawsuits surrounding this IPM failure due to its extreme safety risks to anyone inside a car that will just die in the middle of driving it, especially when their fail-safe system does not get triggered with this particular IPM failure. As of right now, the car is available for inspection because it's still at Cabe Toyota. The invoice shows that the IPM card needs to be replaced. There were NOT any warning lamps, messages, or other symptoms prior to the car shutting off while driving it. It had been running just fine.

I write to report that I asked for help at TOYOTA on the repair of the brake booster pump program. On August 19th, 2021 I took my Toyota Prius 2012 to my nearest dealer, in this case, Toyota of Homestead in Florida, US (I have a screen capture of the appointment); because the brake pump was pumping continuedly every 15 seconds regardless of the vehicle was in motion or stop parked; also the breaking felt like spongy and hesitant. I explained that to the Toyota dealer employee and he told me that the pump running every 15 seconds is not normal and agree that something was not right with my car's brake, but if there is not a MIL light ON, they can not replace my brake booster under the Toyota Program, and I have to pay $170.-first to "scan" the vehicle and make a diagnostic, well I told him that was too much money just to scan the vehicle since there was no light on in the dash the Toyota employee told me I will need to pay for the full brake pump replacement. That was unfair because the Toyota employee agree that definitely the brake was bad, but can not do anything. Took my car home and a few days later September 2nd, the brake lights came on. Well, my wife uses this car daily to transport our kids to school and to do the shopping necessary for food and supplies, and definitely, the cars do NOT break AS IT SHOULD. Toyota employee told me the repair will cost between $3000.- to $4000.-, I took the car to the Dealer when was covered under the Customer Support Program, but the light on the dash should NOT be the main factor to determine that the brake booster needs to be replaced. To be fair TOYOTA should recall all those vehicles. The Toyota dealer employee witness that there was a problem with the pump, and anybody with common sense that know this cars should immediately notice that the sound of the pump going on every 15 seconds is NOT NORMAL. This is my second Prius (My first one was a Toyota Prius C 2014) and I detect almost immediately with something is WRONG.

I was in freeway going home last night after visiting my mom by point loma area San Diego. I was on 8fwy going east, then I merge to 805fwy South which I always and usually take same route. As I went on ramp of 805 South going on a steep high altitude, my 2012 PriusV stall and I can't accelerate when I was stepping into my gas pedal which I have already pushed it all the way in. So I quickly put emergency lights on and slowly guided my car to the right shoulder. I called AAA which I've been a member for so many years. And believe me it is really a life saver. This safety could have been worst from my experience of been driving for more than 30 years. I got it towed all the way home which was about 7 miles. The traffic was heavy on a Saturday night and I waited for almost 2 hours for my towing. When I got up this late Sunday almost noontime, I went out to check on my car and it is still saying "Check Hybrid System" with all the lights on my module was on. I started it and noticed there was an acceleration so I drove it back to my driveway since the tow truck just drop it off on the curveside close by my residence. It drove ok, and then I started my research online and I recently bought a code reader but not sure if it will work on my hybrid 2012 Prius V. Nothing came out on the reader. I called my buddy which was a certified ASE mechanic but has less experience on hybrid. But he has a more expensive code reader and analyser equipment and tools. I also check the Toyota headquarters and you website about my car on safety recalls. I just had taken this vehicle to the dealer for some sort of worldwide safety recalls on all this typical model. I've also read an additional recall and they just have launched it 01/2019. I've plug in my vin# on all of this sites for a check but nothing is coming out. But their complaint is similar to what's going on to my car. It's "Check Hybrid System" and I believe it's the Inverter issues. Please update me and also the Toyota HQ.

The brake, abs, and stability control light come on and the brakes require more pressure to work . getting a code C1391 Abnormal Leak in the Accumulator. but I was never informed of this recall and there are no open recalls associated with my car

******* DELETE VOQ ******* THIS COMPLAINT IS BEING MARKED FOR DELETION BECAUSE THE CONSUMER PLACED THE REQUEST*DJR ******* DELETE VOQ *******

Car suddenly had no pick up. There seems to be problems with the engine accelerating/switching gears. This was extremely dangerous while I was driving. Also If just had the car inspected a few months prior.

Toyota Program ZJB, internal malfunctions of the brake booster assemblies. A known failure of the brake booster than Toyota did extend the warranty on for 10 years BUT would not honor the warranty unless specific diagnostic codes appeared on the vehicle. My issue is that all of the symptoms of the failure occurred on my vehicle (pump constantly running, varying hydraulic pressure resulting in pulsing brake stops, soft brake pedal) but the warranty would not be honored because the diagnostic did not manifest itself. Had technicians tell me that it definitely was this booster failure, but Toyota would not pay for it unless the diagnostic came up. I am now left with a vehicle that has a failed brake system and no monetary support from Toyota. Quoted $2500 to $3000 to repair. Not safe to drive in my opinion with a known failure that I am having trouble getting funding to repair. Contacted Toyota customer support and they reiterated that they would not pay for the repair without the diagnostic occurring and now their extended warranty expired August 31, 2021. Inspection available upon request Safety issue as braking is inconsistent and not predictable Problem was identified by Toyota dealer service department No diagnostic alarms - which is the only symptom not present
