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.

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.

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!

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 i

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.

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.

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.

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.

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.

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.

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 l

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 headquar

Brake Booster assembly has failed on my car preventing the regenerative braking to function normally and it could potentially lead to the brakes failing all together. Upon further research it seems to be a common issues with these vehicles and Toyota has a "Customer Support Program" under the code "ZJB" that will replace the faulty brake booster assembly. My car is still technically covered under the service bulletin that Toyota sent out but when I called several dealers and Toyota corporate, they notified me that my car was ineligible due to mileage. I was quoted over $3,000 at various dealers to replace the part to what amounts to a basically very expensive brake job. I am concerned for my safety in terms of the brakes failing while driving. This is my only vehicle and I have started to resort to driving on the city streets as opposed to the freeway.

There has been a safety recall on my vehicle for the years 2004-2009 models of the Toyota Prius, but my model year is 2012 and I have the exact same issue. 1) My check engine light comes on and off and it appears to be the hybrid electric water pump issue related to the coolant. The cap pops off and spills out. 2) When the light comes on, I am assuming the car is starting to overheat and is putting myself and my 3 year old daughter at risk as this is the primary car we use to transport her. We have just stop taking her out at all due to this issue. When the car overheats, I pull over and it can be risky as sometimes, I am on the highway or local streets. I do not want this issue to cause problems for other other drivers as well while I am trying to pull over where ever I am. 3) The problem as I stated above has been acknowledge by you and Toyota but just for 2004-2009 models. 4) The problem has not been inspected by Toyota, the police, or third party. I have been the only person checking the car and I am using a diagnostic check engine light tool to read the code and looking under the hood to find the coolant pump leaking and popped out just as indicated in the recall for other models. 5) Yes, the check engine light and high temperature light goes on and off. The issue first appeared around November of 2020.

The brakes felt very spongy and the car was having a difficult time coming to a complete stop. The ABS, brake, and stability control lights turned on at the same time. Also, a whirring noise close to the passenger side started happening every 2-3 seconds. After some research I later learned that the noise is most probably coming from a brake pump assembly that has failed and is not able to keep pressure. The car is currently parked since I don’t feel safe to drive it. I contacted a local dealer to see if this part can be changed for free since this is not normal wear and is unsafe. I also learned in online Prius owner forums that there is a large group of Toyota Prius owners with the exact same issue.

THE PROBLEM STARTED WITH A CHIRPING NOISE WHEN THE BRAKE PEDAL IS DEPRESSED. TODAY THE CAR APPEARS TO LOSE REGENERATIVE BRAKING CHARGING. THE VEHICLE STABILITY CONTROL AND ABS LIGHT AND BRAKE LIGHT CAME ON. THE BRAKE APPEARED TO BE MUSHIED.

MORE THAN ONCE I WAS DRIVING ABOUT 40/45MPH, ONCE ON A CURVE, ANYHOW AS I WAS GOING THROUGH THE CURVE IT FELT AS THOUGH THE BRAKES ENGAGED, WITHOUT ME TOUCHING THEM. I UNDERSTAND THE SAFETY THING, HOWEVER AT BOTH INSTANCES IT WAS NOT NECESSARY. IT CAUSED THE CAR TO PULL TO THE LEFT. ALMOST CAUSING ME TO LOOSE CONTROL.

VEHICLE IS MANUFACTURED WITHOUT ANY REGARD FOR PREVENTING MICE FROM ENTERING THE PASSENGER INTERIOR--- AIR INTAKE VENT UNDER WINDSHIELD AND 2 REAR DECOMPRESSION VENTS LOCATED IN THE REAR CARGO COMPARTMENT ABOVE THE WHEEL WELLS ARE OPEN TO THE EXTERIOR ALLOWING UNIMPEDED ACCESS TO THE INTERIOR OF THE CAR. HAD MICE IN THIS CAR 2 WEEKS AFTER PURCHASE IN 2012 AND HAVE BEEN DEALING WITH THIS PROBLEM FOR 7 YEARS. JUST RECENTLY, HAD TOYOTA INSTALL 1/4" HARDWARE CLOTH OVER THESE 3 AREAS AND THIS SHOULD HELP SIGNIFICANTLY TO PREVENT ENTRY. ALL PREVENTATIVE MEASURES TO PREVENT MICE ENTRY HAVE BEEN DILIGENTLY TAKEN BY ME, WITHOUT SUCCESS. MICE CAN MAKE A PERSON VERY SICK. THEIR EXCREMENT CARRIES HANTAVIRUS..... AND THE MICE CARRY TICKS, WHICH CAN LEAD TO LYME DISEASE. SIMPLY MANUFACTURING THE CAR WITH THESE VENTS PROPERLY SCREENED WOULD GREATLY REDUCE THE CHANCE OF OCCUPANTS CONTRACTING A SERIOUS DISEASE.THE MICE ALSO DO A LOT OF DAMAGE TO THE CAR ITSELF, IN MY CAR THE DRIVER SEAT BELT WAS CHEWED, AND I HAVE HAD TO REPLACE THE CABIN AIR FILTER SEVERAL TIMES BECAUSE OF NESTING IN THIS COMPARTMENT(AFTER HAVING BEEN UNKNOWINGLY BREATHING THE MICE EXCREMENT AS THE AIR PASSES THROUGH THIS FILTER ON ITS' WAY TO THE INTERIOR. TOYOTA NEEDS TO BE PRESSURED BY YOUR AGENCY TO CORRECT THIS VERY SERIOUS HEALTH HAZARD THAT THEIR CAR IS PRESENTING. THEIR IS NO LEGITIMATE REASON FOR THIS SITUATION TO EXIST. THE COST TO TOYOTA WOULD BE NEGLIGIBLE.THE BENEFIT TO ALL PRIUS OWNERS WOULD BE VERY SIGNIFICANT

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
