2013 Toyota Prius Complaint Log

My 2013 Toyota Prius with only 99,000 miles is experiencing a brake system failure. The brake warning light, ABS light, and traction control light all illuminate. The brake actuator pump runs every 10 seconds, indicating loss of hydraulic pressure. Safety concern: This issue affects braking performance and disables ABS and traction control, creating a safety hazard, especially in emergency braking situations. This appears to be a known issue with Toyota Prius brake actuator assemblies. Toyota previously issued a warranty extension, but my vehicle is now outside the time window despite low mileage. This failure occurred prematurely and without warning. What happened: The warning lights temporarily went off after adding brake fluid but returned shortly after. The pump continues to cycle frequently, indicating system failure.

Brake booster failed. We were driving on the freeway and almost got into a pile up. Brakes completely stopped working and pedal became very stiff. The more I look it is this is an extremely common issue

My 2013 Prius brake booster aassembly with aster cylinder had to be replaced for the sum $3996.75. Milage on the vehicle was 109,541. The car 's brake light went on and the engine area a buzzing occured. The car was very difficult to stop and I was concerned enough to drive the vehicle home and have it towed to the [XXX] Toyota dealer. I was informed that I needed a brake booster assembly and master cylinder the quote was about four thousand dollars. Attached is my paid bill for $3996.75. The VIN number of the car is [XXX] .

This vehicle qualifies for a repair under T-SB-0024-19. However, this TSB expired in 2023 but the defect and responsibility shouldn't. The car didn't qualify for the repair before the TSB expired, but does now. Because the bulletin was issued and Toyota as acknowledged the repair is needed I have asked them to cover the repair as if it was prior to expiration date. Without the pricey repair, the car is unsafe to drive at no fault of the purchaser. The TSB covers the brake booster and brake booster pump and fail. Do lives have to be put at risk for Toyota to honor and repair the very thing they know is faulty? The car has under 115,000 miles and the issue just started in February. The dealership refuses to provide an itemized repair receipt. The ticket just outlines warranty information of the repair and the second are the techs notes provided via text.

While driving my 2013 Toyota Prius (110,691 miles), multiple warning lights suddenly illuminated on the dashboard, including the ABS, Brake, and Stability Control lights. I initially took the vehicle to an independent specialist (DC Line), but the mechanic there suggested I take it directly to Toyota because his staff recognized this as a known manufacturing defect that should be covered by the manufacturer. A Toyota dealership confirmed diagnostic code C1391, which indicates an internal high-pressure leak in the brake actuator and booster assembly. This is a critical safety defect that causes the brake pedal to become soft and unpredictable, significantly increasing stopping distances and disabling the ABS system. This poses a direct threat to my safety and others on the road. Toyota is fully aware of this defect through Customer Support Program ZJB, but they are refusing to cover the repair because of an arbitrary expiration date they set for 2023. I am currently 40,000 miles under the 150,000-mile limit Toyota established for this exact part failure, yet they are using the 2023 calendar date to deny coverage. Furthermore, I was never properly informed of this defect. Toyota claims they sent a single notification card in 2018, which I never received. I am now being forced to pay $3,000 out of pocket for a manufacturing flaw that even independent mechanics recognize as Toyota’s responsibility. It is unacceptable that a manufacturer can avoid responsibility for a dangerous braking failure by relying on a single postcard and an arbitrary 2023 deadline on a vehicle well under the mileage limit. This should be a mandatory safety recall, as the safety of a vehicle's braking system should not depend on a postcard or a calendar date.

This is the 3rd time I have had to address this issue. The ABS system fails, resulting in increased braking distances. The dealership refuses to warranty or recall this dangerous defect, replacing the parts which fail again. Symptoms include increased braking distance, extremely hard pedal, lack of ABS function, lack of traction control, lack of hybrid regen. The entire dash lights up with indicators for all these functions.

The contact owns a 2013 Toyota Prius. The contact stated that while coming to a stop, the brake pedal was depressed; however, the vehicle unexpectedly lunged forward. The ABS warning light and other unknown warning lights were illuminated. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 65,000.

ABS warning light illuminated and the system failed while driving, causing longer braking distance and reduced steering control during braking. I am concerned this ABS malfunction increased the risk of a crash for me and other road users.

While driving my 2013 Toyota Prius, the red brake warning light, traction control, and ABS warning light suddenly illuminated on the dashboard. The brake pedal became spongy and required significantly more effort to stop the vehicle, indicating reduced braking power. The vehicle was diagnosed with code C1391 — abnormal leak in the brake booster accumulator assembly — a known manufacturing defect acknowledged by Toyota via Customer Support Program bulletin ZG1 for 2010–2015 Prius vehicles. The brake accumulator was replaced by a repair shop (ARC Auto Repair, Pasadena, CA), but the issue has recurred. The symptom is pressure-dependent: brake performance degrades in Eco drive mode as accumulator pressure bleeds down, and partially restores in Power mode when the system is forced to repressurize. Toyota dealership (Hamer Toyota, Mission Hills, CA) and Toyota Customer Experience (1-800-331-4331) both declined to assist, citing expired warranty. This is a known safety-critical defect in the braking system that Toyota has previously acknowledged. No crash or injury occurred, but the reduced braking capability presents a significant safety risk to the driver and public.

I was driving and notice ABS light and other light came on, then noticed that when I tried to brake it felt weak, had to pump brake, then later noticed a leak on brake fluid. I took car to Toyota and they checked it and said brake booster and booster pump needed replacing and they wanted to charge me 3,000 dollars. I could not do the job so I checked around and the auto one in my area informed me that many Toyota Prius’s had a recall on that issue. I made an appointment with Parks Toyota in Deland, Florida to fix problem but when he got there they told me that my car was not on recall for that but was for battery EV fuse but couldn’t do because my engine light was off. I am having such a difficult time with this car. I cannot risk my life and that of others driving with this brake condition if I can’t have the manufacturer or who ever has to to take care of this issue. So far I was able to get a mechanic to do some adjustments so I can drive. I am being very careful and only use it as needed. I stopped looking for a part-time job because I need this fixed first. I am [XXX] , please tell me if I am able to get this recall show for me. Thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving on Saturday January 10th, 2026, when out of nowhere all of my dash warning lights came on and the brakes felt spongy and unresponsive. I had to limp home with 20% of my brake capacity which was very scary. Did some research and it was my brake actuator that went out. Dealer quoted me $4,000 to fix! This is a very common issue with Priuses between 2005-2015 and it's a crime that the part has NOT been recalled. Please put out a recall for this part. Toyota has already had a class-action lawsuit so precedent has been set. I have no idea how I'm going to pay $4,000 to fix this, I'm recently unemployed. Please hold Toyota liable!

The brake actuator/ABS hydraulic system on my 2013 Toyota Prius failed. The component is available for inspection upon request, as it was replaced by a Toyota dealership. Prior to failure, the vehicle intermittently displayed ABS, Traction Control, and VSC warning lights while driving, which would sometimes clear on their own but eventually became persistent. This condition reduced or disabled ABS, traction control, and vehicle stability functions, increasing the risk of loss of control or reduced braking effectiveness, particularly in emergency braking or low-traction conditions. The problem was reproduced and confirmed by a Toyota dealer, who diagnosed the failure using diagnostic code C1391 indicating internal brake actuator malfunction. The vehicle was inspected by the manufacturer’s authorized dealer, who replaced the brake actuator assembly after three days of repair at a cost of approximately $3,000. Warning lamps were present for months prior to the final repair and gradually progressed from intermittent to constant, indicating a worsening failure of a known issue affecting this generation of Prius vehicles.

Red brake light came on, traction control light came on, ABS light came on, Toyota says my brake pump needs replaced. That my brake will fail.

On [XXX], we were driving from Coalinga, CA to Phoenix, AZ for Thanksgiving. As we began to descend into Los Angeles on [XXX], three warning indicators suddenly went on: the ABS warning light, the traction control light and the brake warning light. The brakes still worked but the brake assist was weakened. We pulled over as soon as possible at the nearest AutoZone. The employee performed a standard handheld OBD-II scan of the vehicle and did not detect any issues. We continued on our way through Los Angeles and to San Bernadino where we were spending the night. At one point the indicator lights went off for a few minutes but then came back on. We spent the night in San Bernadino, and the next day (11/26/2025), we took the car into the San Bernadino Toyota Dealership as we felt it was unsafe to keep driving. The dealer conducted a thorough full brake and hybrid system diagnostic and confirmed that the failure was inside the brake booster system. The repair estimate states: "Brake booster assembly with master cylinder and brake booster pump assembly have an internal leak." Thus, Toyota's own technician identified an internal hydraulic leak within the booster system, affecting the booster assembly, master cylinder, and booster pump assembly. The total repair estimate is $3,959.99. This is a major safety defect affecting sealed hydraulic components that are not part of routine wear-and-tear. There were 4 people in the car. Fortunately, the brake failure did not result in an accident, but it could have if we had kept driving on to our destination. We contacted the Toyota Brand Engagement Center to ask for Goodwill Assistance, but they were unable to help us. In addition to the repair costs, we have incurred rental car costs.

Crack in the Engine. I had been following the recommended Maintenance schedule, but I suddenly had issues where the engine would stall/stutter on activation (switching from electric to motor operation). The check engine light came on, and I immediately took it to the dealer who replaced the battery and spark plugs saying that was the issue. That solution did not even last a month, as I had sometimes severe shaking in the engine along with the stutter. I again brought it to the dealership who told me that the actual problem was a cracked head gasket and that the vehicle was "mechanically totaled". I was lucky that I live close to the dealership and worry what would have happened if I had to drive on it further.

brakes had no stopping power. Normally when braking it was smooth. All the lights went on. Toyota dealer confirmed that the brake booster Pump Assembly and Brake Master Assembly needs to be replaced.

My daughter was driving the 2013 Toyota Prius on the interstate in Chattanooga, TN. The brakes did not feel right and the car was very difficult to stop. (It did not brake at a normal distance) My daughter was able to get someone safely, and she had the car towed to the dealer. My daughter's life was endangered by this brake booster failure, but there is no recall listed on the vehicle. Also, when I Googled the issue, I found that it is a well-known and common problem in this year Prius. The brake booster failure is due to a Toyota design flaw, and Toyota is apparently being sued for it. Why is this issue not listed as a recall? I would not have allowed my daughter to drive around in a car for which the brakes are known to fail. How many accidents and deaths will be caused by this problem before Toyota stands behind their product and recalls affected vehicles? I had to pay $3200 for this brake repair, even though it is caused by Toyota's design flaw and endangered my family's life. My family owns four Toyotas, and I do think they make the most reliable vehicles on the road. I cannot understand why there is not a recall, and they are not standing behind their product.

Brake actuator went out on 2013 Toyota Prius Gen 5. The part is very expensive and in my opinion is a part that should not have to be replaced. The care has 120,000 miles. It is driven very softly, meaning not fast and hard but commuting to work and grocery store as needed. A nice commuter. It is not fast but gets you there. The actuator put me at risk as stepping on the brake was hard and the car did not want to stop and I was close to hitting the car in front of me. All the lights came on at the dashboard and I was very scared to continue to drive and had to get a tow truck.

My 2013 Prius Plug-In Hybrid with 131k miles on it showed the ABS, Brake, and Traction Control lights while driving last week. Diagnostics from auto shop showed DTC code C1391. System is available for inspection upon request. Safety is definitely at risk, since I am needing to drive it around to assess the issue, and brakes could fail at any time. Vehicle has not been inspected by the manufacturer, police, insurance representatives or others. After speaking to Toyota, I was informed that--although under 150k miles--my car is not covered by the extended warranty because it is 2 years past the 10 year requirement. I drove my car very little between 2020-2022 because of the global pandemic. This is a very common issue with 2012-2015 models caused by a defective part, and it's likely that the problem does not commonly present itself until after the warranty expires.

Last night, the brakes stopped responding, warning lights came on (ABS warning light, brake system warning light, and the slip indicator light). This morning, a local auto repair shop diagnosed the problem as a failed brake booster assembly. This is a safety issue and we have been told we have no option but to pay to replace the entire assembly. The repair shop has contacted the local Toyota dealership, from which we have to purchase the replacement brake booster assembly.

The brake booster fail and I'm at like 140k. It was very scary when it happen to me today. I press on the brake think it would brake like normal but no. It kept sliding. I felt like I was going to crash. I don't have any paper report on it yet but they are certain it's the brake booster.

I had my car serviced Oct 21 and when I picked it up the vehicle brakes made a whooshing noise and felt spongy. I thought it must be ok as they had just serviced it but when it became apparent this could be a problem I took it back Nov 1 and was told the hydraulic brake booster pump needing replacing at the cost of $3400. I was shocked as they told me it could break completely AT ANY TIME but the brakes would still work. I decided to drive it home as that is an enormous car repair bill and I would have to get financing or get a different car. I didn't want to make rash decisions. I investigated the issue and found out this was a recall for these vehicles for 2010 through 2019 models. This same dealer did not mention this to me at the time of sale, that they had been subject to a recall, and since I did not have them inspect the car immediately after service (I had to miss work and my son drove me after he was off work and I feared they would close before I arrived so I had them park the car outside and the sales desk had the key). I thought I would drive it but after reflection I do not want to endanger other people if my brakes fail. This is a clear violation of the public trust that these cars are yet on the road.

while driving the 2013 Prius hybrid , the ABS , brake light, and traction control lights came on. The brake was rock hard and the car would not stop at the light, causing me to swerve away from the cars in front of me and pull into a nearby parking lot. The brake would not work. There is a constant beeping noise in the car , which is a brake warning. I looked up the problem and just like many other Prius owners, there is a brake booster and brake accumulator issue and Toyota is not owning up to this problem. Many Toyota Prius owners are complaining of this loss of brakes issue. How long until NHTSA forces Toyota to do a proper recall about this very dangerous loss of brakes issue ??? They recalled a few vehicles, but the recall does not seem to cover many Prius vehicle owners that are complaining. Mine has 140 000 miles now, but this part is failing even on cars with 40 000 miles. Toyota knows very well that they have a big serious issue costing upwards of $4000 to fix. They are just refusing to recall this issue. NHTSA has to address this issue please. They are many complaints about this loss of brakes issue.

ABS, BRAKE AND Stability lights came on, i have to press all the way down the brake pedal for car to stop.

Full brake actuator assembly failed. Brakes started responding differently and we became uncomfortable with driving the car. Problem was confirmed by ISC. The part has not been inspected, but I will ask them to save the part for me. No, it all happened at once while driving at speed on the freeway.

Entering the highway the car suddenly learched and stopped excelerating, creating an unsafe situation, and went into a slow mode. It limped along. Caused cars issue around having to slow merge and driving only 10-15 miles per hour. The dealer could find no codes and said it could be an air bubble in fluid line??? No warning lights.

The Toyota brake booster system failed and is no longer safe to be on the road. The car will no longer brake properly and is a danger to anyone else on the road. It was inspected by Toyota prior. The entire dashboard warning lights for the brake system lit up 2 years ago and has fully failed now.

The brake pedals felt very soft with no resistance and barely had braking power. Was taken to dealership and they said it’s the brake booster which was a common thing on these cars, but there’s no recall to fix it and they won’t replace it.

I have a 2013 Toyota Prius with 164,000 miles. A mechanic confirmed that the master cylinder and brake booster are failing and are not covered since warranty expired 14,000 miles ago. I have heard this is a common issue with this vehicle. Traction light, brake light and ABS light are all on. The earring lights go on and off.

when test driving the vehicle I asked about this buzzing/ whirring noise while sitting in the running but parked car. I was told these cars are hybrids, the electrical components make all sorts of whirring and humming noises and not to be concerned. Over the years I heard this noise, increasingly more and more, but I never knew it was something to pay attention to. Fast forward to July 2025. I noticed the car is inching forward while I’ve been stopped for a while at a red light almost like the brakes don’t want to hold. This has been happening so often that I have began to put the car in park while waiting for lights to turn green because it gets painful having to push the brake so far down. I take my car to a mechanic, explain all of the noises and the sensations and two mechanics Drive it but say it feels fine and there are no recalls. They say my front brake pads are low and that must be what I’m feeling. After replacing the brake pads nothing had changed. Now there is also a squeak while moving at a slow speed in stop and go traffic. 1 week later i bring it up while getting an oil change and ask if they know what it could be. They said brakes seemed fine. A couple weeks go by and yesterday while I was driving down the highway in heavy school traffic out of nowhere my car makes a clunk noise and all of these lights pop up on the dash. I roll the windows down and scream for my children to hold on because something was wrong. Luckily we were able to get to safety but I definitely had reduced breaking capabilities. I immediately take the car in and and find out my brake booster and accumulator has failed. service tech brings up the consumer program but my car is a 2013 and it is not eligible to be repaired bc it’s 10+ yrs. Even though Toyota admits to internal malfunctions of the Brake Booster Assembly, and my car is only at 76,000 mi it’s not being fixed. This is negligence on Toyotas part. Not fixing these faulty parts is endangering lives.

The contact owns a 2013 Toyota Prius. The contact stated that while reversing, there was an abnormally loud sound coming from the vehicle. The contact exited the vehicle and performed an inspection of the vehicle. While inspecting the vehicle, the contact became aware that the passenger’s side rear wheel was touching the frame of the wheel well. Additionally, the wheel was leaning inward. The dealer was made aware of the failure but provided no assistance. The vehicle was towed to an independent mechanic, where it was diagnosed with a fractured rear wheel assembly. The contact was informed that the rear wheel assembly needed to be replaced. The vehicle was being repaired. In addition, the contact was informed that the failure was a known failure. The contact was informed by the independent mechanic that two similar vehicles had been repaired with similar failures, within the week. The manufacturer was not made aware of the failure. The failure mileage was approximately 179,000.

I was driving normally, about 30 mph in a residential area and the brakes all of sudden became soft. It was very scary and I didn’t know if it was safe to drive the vehicle. The brake, ABS, and traction control sign all came on at the same time. I scanned the car and it was a C1391 error code. The Toyota dealership said it is not covered under any recalls. I called Toyota and asked about the ZJB program that covered the repair but they said it expires. Toyota has a repair program for the defective part but no longer covers it. This issue is a known manufacturing issue and it’s dangerous. Toyota should cover it free of charge.

Failed brake booster, pump, fluid, and actuator on my Toyota Prius 2013 with 143,972 miles on it.

When I’ve hit a pothole or hit the breaks to hard by ABS, and traction control lights would come on and then turn off. The other day they all turned on and stayed on with the break light on as well. Breaks all seemed to work fine, just a little spongy. I brought it in to a shop and they estimated 3k to repair Remove, replace, calibrate, and bleed ABS accumulator assembly and brake master cylinder assembly. Test drive-New OEM Toyota Parts. These parts were recalled but only up to 10 years or 150k miles. I’m at 164k so ineligible for the recall but if this part completely failed while I was driving I could have been killed or caused someone serious harm.

Brake booster, ABS controller, and brake booster pump have failed for a second time. Parts replaced with new, in box from aftermarket dealer. Dealer/Manufacturer refuses to accept that there are design flaws and will not recall.

The hybrid braking systems on Toyota Prius' manufactured from 2010-2015 had a serious failure of the hybrid braking system that had additional long term warranties to repair, but never recalled in order to save the money from a total recall. The Sloan Toyota dealership in Glenside knew before I purchased the 2013 Toyota Prius I purchased that a serious brake system failure was very probable with my car but failed to tell me. If they did, i would not have purchased the car. I had the 5000 mile oil change in early August and three days later after the service and a clear 25 point inspection, and the system failed. I want full reimbursement or just pay for the repair.

I am experiencing the issue described in the BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES recall issued by Toyota for the Prius, which for me ended in 2023. The vehicle is unsafe to drive without performing this $4000 repair (dealer cost), which is almost more than my car is worth. Toyota should issue another extension for the repair coverage since they are known to be faulty. The previous recall and extension of the recall can be found here: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ABS system and the brake actuator began to fail, which triggered multiple warning lights. The Toyota dealership service department confirmed that the Anti-lock brake system and the actuator needed to be replaced, a $3800 value.

There has always been this ringing sound when releasing the brakes. I had it looked at and was told there was no issue. Then while driving it felt like the brakes locked and all of the sensors came on the dashboard. I had those scanned and was told they were sensor issues but car started driving/braking ok. Few days later everything locked up. I can’t push the brake at all. I was told the Brake Booster Pump Assembly with Accumulator was shot. So i began research and saw hundreds of complaints for the exact thing in my make and model and year. This could have killed someone had it happened on a highway. This should be a recall, major issue that numerous are experiencing.

For last 4 years i have been noticing a hissing sound when brake pedal is pressed. At first it was unclear to me where it could be coming from, and no indicator light has triggered. I have brought this to the attention of toyota dealership when i first noticed it and the individual couldn't really make out what it was. The sound has now gotten worse, and upon further studies i am learning that there was indeed a recall pertaining to the brake booster and actuator, but my car for some reason is not included. This is a major safety issue and i expect toyota to help resolve. Please help.

The Brake Booster and Brake Booster Pump Assembly have failed. They have caused the following warning lights to go on: ABS, Brake System waring light, Slip Indicator Light, and the Electric Power Steering light.

Pulled out of the driveway drove about a 100 ft heard large clunking sound front end dropped down as if there was a flat tire pulled off the highway drove through the grass 100 ft back to my home the car started smoking from the engine compartment and burst into flames. Tried to extinguish with fire extinguishers and water hose while calling 911. Fire Department extinguished the fire. Car is a complete loss. There was an oil leak trail from where the car first drop down through the grass. The car did not have a previous oil leak. The car had 300,000 miles on it. No one was injured.

Break booster issue. Car only has 63,465 miles. Toyota has received reports about certain internal malfunctions of the brake booster. Problem is, not many have had luck getting the part covered because it's likely that the problem does not commonly present itself until after the warranty expires.

The ABS system has failed, and I have to pony up $3000 + for repair, since the warranty extension from Toyota has expired - 10 years since first use (even though I have only had it for 5 years). I have less than 150,000 miles on this car, which is the the other parameter for service coverage for this problem. Toyota knows these parts fail, and they extended the warranty, BUT there is no recourse if your car is over the 10 year limit, even if under the mileage limit. it is a safety issue and should be addressed no matter the age of the car. I can't afford the cost of repair and so will gamble on not needing to use the antilock brakes.

6/12/25 I'm driving my 2013 Prius w 123K m through a construction zone. The road became bumpy and when I depressed the brake nothing happened. Thinking I must have hit air or be imagining things I tried the other pedal. The acceleration re-oriented me to the fact that my brakes were non-existent. Many lights I've never seen illuminated on the dash as I looked into my mothers eyes to say we had no brakes. I was somehow able to pull safely. After the initial loss of braking I discovered I had a small amount of stop if I put the pedal on the floor. The closest local shop thought most of the internal braking system related to the pump and actuator would need to be replaced but requested I get an opinion from Toyota. At drop off I had requested they top off the brake fluid, despite their informing me that was never necessary. Perhaps this repressurized the system because upon visiting the car all dash lights were off and the brakes felt normalish. The shop did not know why. This is my only transportation.At 9:30 in the AM 6/14/25 I proceeded to the closest Toyota dealership w the safest direct route slowly with hazard lights and lots of space from other cars. While waiting for diagnosis I discovered this exact issue was a known defect and had been the subject of a class action lawsuit and customer service bulletin of which i had no notice. Since 2022/2023 the car had been briefly and consistently losing traction over minor bumpy conditions. Without notice of the issue I had no way to know this was a precursor to Total brake failure. This car was serviced at 3 Toyota dealerships during the extended warranty authorized by the CSB. I was never apprised of the potential issue, and expressly requested a list of recalls related to my vehicle at Lumberton Toyota in 2022 which they refused to provide. I therefore googled recalls, but this issue was not a recall. I have never heard of a CSB. Two Toyota dealers quoted me the full price to replace the braking system, $3,273.94.

my 2013, Toyota Prius recently suffered a sudden hybrid system failure with DTC space P0A0F and a check hybrid system warning. This matches the symptoms described in NHTS a safety recall 20V369000. Your recall look up tool shows my Vin is not included. However, I have never received this recall repair, and my failure is identical to the documented safety issue. I am requesting help in getting Toyota to complete a goodwill repair or warranty extension review as this is clearly a safety related inverter failure for which Toyota has acknowledged responsibility and similar vehicles.

My vehicle displays the anti-skid light when brakes are applied. I also hear a chirping noise and brake pump activation noise when the vehicle's brakes are utilized and as the vehicle is stopped. Information on the internet indicates this is a serious issue with the Prius Gen III brake system, requiring replacement of the hydraulic brake booster and pump. This brake failure should not be happening, and Toyota has already identified this problem. This Prius has been trouble free up to this point and has ~185,000 miles.

My prius have a scan code: C1391 and my brakes don’t work good i almost crash. And I traying to see what happen online but i see hundreds and hundreds, of prius with this problems, you need to do something and do a Recall. This is a recurring problem with Prius models, and they never do anything about it. It seems like Toyota is paying someone not to do the recall.

My electronic brake booster failed at just under 215000 miles, causing a brake line to snap. I now have to get the car towed 40 miles at my expense for a costly replacement of this major component, which Toyota already conceded was faulty by virtue of extending the warranty to 2023.

Brakes failed to provide sufficient power to stop car. Towed to garage where FIXD was plugged in OPBD port and received code "C1391." Cost to replace parts and labor is $3,002.42.
