2012 Toyota Prius Complaint Log

The contact owns a 2012 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the ABS module software needed to be updated. The manufacturer was not made aware of the failure. The failure mileage was approximately 53,000.

Suspected Brake Booster failure. We have been experiencing our brake booster running several times a minute and something felt off. In December, we took it to the dealership who said they "were unable to replicate the issue". We found that odd since we experience the issue every few minutes, but we believed them when they said that there was nothing wrong with our brakes. Yesterday, about one month later, we were driving on a busy street when our brakes appeared to fail. We couldn't make the car stop, three dashboard lights came on (the ABS and two others) and eventually we realized the brakes had to be pressed really hard to get the car to stop. We avoided an accident, pulled into a parking lot, turned off the car, checked the brake fluid (the brake fluid was fine), restarted the car and the lights still remained and the brakes continued to not compress easily. We called our Toyota dealer who said that there is no recall on our Brake Booster and that this is not a known issue, and yet there are hundreds of readily available accounts of 2012 prius owners who experience the same fail.

Seatbelt does not retract or lock properly when braking.

Our 2012 Toyota Prius experienced brake failure due to the Accuator and Accumulator. I contacted Toyota Corporate office, which advised it is a known problem and had a customer support program that expired last year. The Toyota rep advised me to not drive the vehicle because of the brake failure and opened a ticket advising it is a known issue. After researching online, it is a very common issue. https://www.aboutautomobile.com/Consumer-Complaint/2010/Toyota/Prius/Brake

The contact owns a 2012 Toyota Prius. The contact stated while driving approximately 40 MPH, the brakes became inoperable. The ABS and traction control warning lights were illuminated. The vehicle was taken to an unknown local dealer where it was diagnosed that the brake booster and brake pump assembly needed to be replaced. The vehicle was not repaired. The manufacturer was contacted but no additional assistance was provided. The failure mileage was approximately 335,000.

I was driving at night and several brake related dashboard lights suddenly lit up and I wasn’t able to use my brakes. I managed to coast safely to a stop, called a tow truck, and got my car home. Mechanic found a c1391 code and told me to go to Toyota. Toyota says the accumulator has a leak and it causes the brake up issue, but the service plan free program to fix it expired. They want $5000 to fix it. I want Toyota to extend the plan because I didn’t drive as much during the pandemic and I would have had the issue earlier had I been driving at normal amounts,

Headlamp Lens Issue Vehicle Manufacturers Must Correct ISSUE 1. The increase in pedestrian-vehicular accidents and fatalities is, at times, related to the driver not seeing the person in time to stop. Not seeing a person in time may be related to poor street lighting or a decrease in front visibility caused by fogged headlamp lenses. Current nighttime traffic has a variety of vehicles operating with varying front light visibility. 2. For certain vehicles, the lens alone is replaceable. With other vehicle models, the entire front lamp must be replaced. The exorbitant cost of replacing the front lamp is causing some people to opt to drive with densely fogged front headlight lenses risking pedestrian safety. 3. Some car dealership offer a "defogging" cleaning service for greater visibility but does not guarantee to restore the car's front illumination to minimum required safety standards. Recommendation Require vehicle manufacturers to make front headlights with detachable lenses, or make the lenses fog proof. A replaceable lens is cost effective for all income individuals. Making lens replacement affordable may decrease the number of pedestrian-vehicular accidents and fatalities. Discussion The headlight lens of my car became increasingly fogged, overtime, decreasing night visibility ahead. The Toyota dealership offered a $300 cleaning service for both lenses or replacing the headlamp at about $300 each; $600. I opted for the cleaning. When completed, the headlight lens of my vehicle looking much less fogged. When I asked, the dealership told me that their cleaning service does not guarantee compliance with minimum front safety illumination for night driving. I was told that my car does not come with removable lenses. To ensure minimum safety front night visibility, I purchase new headlamps total costing about $300 each; I spent $900 because the $300 cleaning service was completed and not deductible. I contacted Toyota management and went up the chain of command

The Brake Booster or Actuator is failing, without any indication or warning lights on the dash alarming us to the problem. The car has been making weird sounds, but after being inspected, this, according to the Authorized Toyota Dealer, on December 22, 2022, is a life-threatening and very dangerous malfunction to myself and others around me when driving. This is the first hybrid car we have owned, and we thought the noises we had been hearing for a couple years was normal, because there were no warning lights coming on to tell us otherwise. The dealer did not want us to drive the car any further due to the danger of the problem. We asked the dealer to repair the problem without charge, but that request was denied by the Toyota Brand Engagement Center (Case 221222000587). The dealer is currently repairing the malfunction at a cost of approximately $2650 plus tax). We are highly disappointed with Toyota not repairing this known problem under a dealer recall.

Purchased 2012 Prius used. Replaced low beams and high beam headlights shortly after. Passenger side low beam is no longer working (bulb was replaced 3 months ago). Upon googling causes saw 2010-2011 Prius had a recall for recurrent headlight issues, the wiring harness was replaced in them. It seem the 2012 is having the same issue in the 8 pages of complaints on exterior lightning that I saw. Toyota should extend the fix to include 2012 Prius.

The car has been diagnosed by a Toyota dealership as having an internal leak in the Brake Booster and Accumulator, both are part of the brake system. Repair estimate of $3800 00 dlls. Currently i have 3 check lights on, Brake, ABS and Traction control. All controlled by the same module

My prius got ABS, Brake, Traction light on when I was on traffic in the highway. Car lost brake power. Regenerative brake does not. It takes longer to stop the car. TOYOTA NEEDS TO FIX THIS. THE ABS MODULE IS GONNA FAIL AT SOME POINT. Dealership asks $5000 to fix. C1391

All the lights on my dash lit up. I took it immediately to Toyota of Dallas . I tried numerous times connecting with Dimatrius service manager. No call back. An inspection was done on the vehicle. He stated it would be a $5000 job and I was out of warranty. Their is too many people having this issue if you search many 2012-2014 people are having this issue in a addition to to a google search search for a letter at Capistrano Toyota.

In September 2022, my car, a 2012 Toyota Prius V with 79, 056 miles, began making noises in the engine area and the brakes became loose, meaning it took more pressure on the brake pedal to engage the brakes. In November 2022 the following warning lamps on the dashboard came on: Master Warning Light, Brake System Warning Light and Warning Buzzer, Brake System Warning Light, ABS Warning Light and SLIP Indicator. I took it to the Toyota Dealership near me: Lipton Toyota in Ft. Lauderdale, FL, and they diagnosed car with the trouble code of C1391-Abnormal Leak of Accumulator, Internal ABS Actuator Failure. To fix this problem, Lipton Toyota will charge $3124.29 for the repair. Toyota Motor Sales, U.S.A., Inc. issued a customer support program notification that would cover this repair if the malfunctions happened before coverage ended. Primary Coverage was applicable until December 31, 2021 with no year/mileage limitation. Secondary Coverage was applicable for 10 years from the vehicle's date of first use or 150,000 whichever occurs first. Date of first use on my Prius V was 03/01/2012 and my mileage is 79K. So as you can see, I am just out of the coverage window. My private mechanic and myself have appealed our case to Toyota that this problem should be a recall with no limits on coverage. (Toyota Motor Sales, U.S.A., Inc. - case reference # 230206000678) I believe that if I had driven my car more, (which was not done because of the Pandemic 2020-2021) this issue would have come up before the cut off date for repair coverage. I also believe that this problem with the Brake Booster and Brake Booster Pump Assemblies on certain 2012-2014 model year Prius V vehicles should be a recall.

At 106K miles and after 10 years and 8 months in service (new vehicle bought in March 2012) Brake booster internal leak, code c1391. Brake light, ABS light and VSC light stay on. Can not drive it as the brake booster internal leak is making the brakes spongy and slow in response. Talked to Toyota and they said it is out of warranty and the deal is estimating $2000 plus for the repair. Miles on my cars 106K are way less than 150,000 allowed by Program Service bulletin ZJB (attached) but Toyota is denying repair coverage as the vehicle life is eight months more than 10 year limit since first use. Did not drive it much within the last two years because of working from home due to covid 19. Had it been driven more frequently the brake system failure would have happened way earlier as the internal leak (possible fatigue failure causing leak) should be more related to driven miles and brake system cycling of pressurizing and depressurizing than just being parked on the drive way. Would request if NHTSA could extend the duration of ZJB bulletin considering the fact that many drivers did not drive that much in the last two years due to working from home and this internal leakage failure can be related to fatigue loading of the hydraulic components and the number of fatigue cycle are directly proportional to the driven miles and not the life of the vehicle. Thanks

The brakes on my 2012 Toyota Prius failed suddenly with little warning after starting the car, and when I began driving off in a busy Walmart parking. I was startled when I felt that the brakes did not seem to work, nearly causing me to collide with the car in front of me. I had to quickly depress the brake pedal to bring the car to a stop. The normal braking power was greatly reduced when I depressed the brake pedal, and I had to use more force to bring the vehicle to a stop. Only when I looked down did I see that some of the dashboard lights relating to the brake system stayed lit and not turn off like they normally do. These lights appear to be brake warning, ABS warning, and anti-skidding lights. The brake problem has been inspected and confirmed by both an independent service center as well as the Toyota dealer. The failed brake component was diagnosed as an abnormal leak in the accumulator, and the brake booster with master cylinder assembly requiring replacement, with the code #c1391. After having done some research, it appears that this exact brake problem seems to be afflicting many such generation Toyota Prius vehicles, and the manufacturer Toyota was aware of this problem existing in such vehicles.

The brake system (accumulator/booster) has failed and reduced stopping ability. Error code is C1391

The contact owns a 2012 Toyota Prius. The contact stated that while driving at various speeds, the ABS warning light illuminated and the vehicle skidded while depressing the brake pedal. The contact stated that the hazard lights independently activated and caused the battery to drain, and the vehicle would stall. The vehicle was taken to a dealer where the contact was informed that there was a Customer Satisfaction Program for the failure, but the Customer Satisfaction Program had expired. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 120,000.

The contact owns a 2012 Toyota Prius. The contact stated that while driving approximately 50 MPH, the ABS, brakes, and traction control warning lights illuminated. The brakes became inoperable, but the driver was able to regain control of the vehicle and pulled over. The vehicle was taken to the local dealer where it was diagnosed there was a hydro pump motor fault and hydro motor pump relay fault with codes C1252 and C1253 and the hydro boost brake pump kit and brake assembly needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and referred him to the NHTSA hotline. The approximate failure mileage was 97,000.

I am having issues with my Toyota I was never contacted NHTSA CAMPAIGN ID: 18V684000. My car has failed numerous times.

During a hard braking, felt brake pedal softer and less responsive braking. Now ABS Icon, Brake Icon, and Traction Icon is on. Confirmed Code P1391 in ABS system.

As I was driving, all of the brake lights turned on on the dashboard. The moment the lights turned on the brake power felt low on heavier pedal depression. I took the car in to the dealership for assessment and said they found internal failure of both brake actuator and booster and recommended replacement of both actuator pump and booster. I have had both the parts replaced and after now the second replacement of the master cylinder, there is still an error code for the pressure cylinder and all the brake lights are on.

I was driving on the expressway and experienced a sudden loss of power. The internal combustion engine suddenly stopped and did not deliver any power to the wheels. I immediately received a message on the system that said 'Check Hybrid System Stop Vehicle in a Safe Place'. The electric motor still continued to provide some power with the available battery charge. I was able to make it to the shoulder of the road but it was challenging to get to the shoulder with no power or warning and high speed traffic. My wife and I were in the vehicle. The vehicle had no engine or error codes until the failure on the expressway. The vehicle has the code P0A1A and P0A94. This is consistent with the error codes in the NHTSA 19V491000 recall and Toyota Safety Recalls E0E and F0R.

My breakes failed when driving. I almost got in accident. Code C1391. Brake Actuaror Failure. car has 200,000 miles. Toyota is denying to repair the car. It is well known problem with that but still not fixing.

2012 Toyota Prius V, 125k. Sudden loss of braking power accompanied with BRAKE, BRAKE SYSTEM, SLIP INDICATOR, and PCS warning lights. Scan shows codes B2060 (ABS malfunction) and C1931 (Abnormal leak of brake ACC pressure). Brake fluid significantly lower. No signs of external leak. Can hear the brake booster pump running almost constantly. All signs indicate this is the issue identified in Customer Support Program 20TE07. This is a significant safety issue that may lead to loss of braking and serious injury / death. It should be a recall.

Small internal brake fluid leak inside the break booster assembly with master cilinder. Code c1391

The brake booster pump has started to run every 30 seconds while the car is operating. When pressing on the brakes, there is an unusual sound and has begun to feel different. There are no warning lights yet, but after consulting with the local Toyota dealership they informed me of the ZJB Customer Assistance Program which addresses this issue. Unfortunately the offer to repair has expired and the dealership has declined coverage. I contacted Corporate Toyota and they are declining to cover the repair. I don't have the $3500 to replace this brake booster pump at this time. This is a safety concern and I don't understand how this is not a RECALL due to the potential safety concern. PLEASE HOLD TOYOTA ACCOUNTABLE TO THIS SAFETY PROBLEM.

Had blown gasket repair last year (which was fixed by my local Toyota Dealership and all cost paid for by myself). Dealership acknowledged that there were known issues with failures due to clogged EGR's and out-dated manifolds. Was never recalled and did not know about the issue until after the incident. Wanted to report issues since it appears countless other have been in the same situation with gen 3 Prius. Toyota needs to be offering EGR cleanings and updated manifolds at no cost and reimbursing customer's for previous repairs.

The contact owns a 2012 Toyota Prius V. The contact stated while driving approximately 40 MPH, the brake pedal was depressed with excessive force; however, the brakes failed to respond as needed. The contact stated that five unknown warning lights were illuminated. The contact then stated that the failure was reoccurring while driving at various speeds. The vehicle was taken to the dealer where an outside technician diagnosed the failure as five unknown fault codes related to the brakes. The contact stated that the brake booster and actuator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the VIN was not included in a recall. The failure mileage was approximately 211,000.

The contact owns a 2012 Toyota Prius V. The contact stated while driving 30 MPH, the vehicle stalled inadvertently. Several unknown warning lights were illuminated. Additionally, the brake pedal was depressed but failed to respond. The contact veered to the side of the road and intentionally struck the curb to stop the vehicle. The vehicle failed to restart. The contact stated that the vehicle later restarted and was driven to the dealer. The dealer diagnosed that the ABS actuator had failed and 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 because an unknown Toyota Courtesy Program issued for the failure had expired. The failure mileage was approximately 160,000.

While on the freeway, I was braking due to traffic and the car started shaking and the ABS light, "BRAKE" light and traction light all came on and remained on. The brake system did not operate properly, which nearly caused a collision.

I have a 2012 Toyota Prius that the Toyota dealership has confirmed that I have a failed ABS actuator and is displaying the correct repair codes for the service bulletin but they refusing to cover any of the costs to replace the ABS actuator and boost pump. Since the failure of the ABS actuator I have had 2 close calls where I needed to stop fast and my tires locked up, I lost control of the car and spun out but luckily I did not hit anything. The brake, ABS, and 2 other warning lights have come on and off intermittently on the dashboard of my 2012 Toyota Prius. I summited a good faith request to the repair my Toyota Prius ABS actuator at Toyota of Anaheim on 10/28/2022 and due to it being 20 days past the 10 year limit and slightly over the 150,000 mile limit at 158,000 they say that I'm 100% responsible for the repair costs of $3,231.78. This proven design flaw is not my fault, it did not occur under normal wear and tear and the brake ABS actuator and boost pump should last much longer than it did. Now I'm faced with paying a huge bill for the repair or pick up my Prius from the dealership and drive it home with a defective ABS actuator. This is another example that Toyota is placing profit ahead of safety.

My 2012 Toyota Prius V went out and had no control crashing into the curb on the passenger side. Scraping the side of my car. My ABS break system went out on my car going 40 miles per hour at 5:30 on a major street in Los Angeles called Wilshire Blvd. I almost died if I had not crashed into the curb I would have been hurt and hurt others Toyota issues a wait and see “courtesy program of a certain window to fix the break booster system and I ran out 1 month ago. My car is at Toyota Culver City and they are refusing to fix the break system due to the time limit. I was not notified of break system faulty system. My number is [XXX] if you would like to know INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I was driving on highway & the vehicle stopped accelerating as I was pressing the gas. I put my hazards on & got to the side of the road. Then the eps light came on & the dash stopped showing the mph. The ac stopped blowing cold air & the windows were working slow. I turned car off then back on a couple of times then more lights came on. No lights were on prior to this & I haven’t had any problems w the vehicle before this. I just got this car & I feel like it has something to do with a recall but no one wants to take responsibility for the issue.

No problem

The contact owns a 2012 Toyota Prius V. The contact stated while driving approximately 65 MPH, the vehicle stalled. The contact stated that the power steering and power brakes failed to operate as needed. The contact stated that the check hybrid system and check battery warning lights were illuminated. The contact pulled off the roadway safely but was unable to restart the vehicle. The contact had the vehicle towed to an independent mechanic, who diagnosed the vehicle and determined that the inverter needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 18V684000 (Hybrid Propulsion System). The manufacturer had not been informed of the failure. The failure mileage was approximately 247,000.

The contact owns a 2012 Toyota Prius. The contact stated that while driving at an undisclosed speed, the brake warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the brake master cylinder and brake booster needed to be replaced; however, the dealer informed the contact that the repair was not covered under warranty. The vehicle was not repaired. The contact stated that the failure recurred while driving and the vehicle hesitated while the brake pedal was depressed. The contact slammed on the brake pedal and the vehicle came to a complete stop. The vehicle was towed to the residence. The manufacturer was not made aware of the failure. The failure mileage was 185,519.

While commuting home by Prius has the traction control, ABS, brake light, and brake system indicator dash lights activate. I was able to make it to an autoparts store and the code C1391 was displayed. Researching this code points me to a safety issue that Toyota is aware of and their remedy ended in 2021. Toyota should warranty this known issue, especially for those people who were never notified of the failure of the brake accumulator and brake booster. I now am afraid to drive my vehicle due to potential failure of the brake system and the costs of the repairs are really expensive.

Master cylinder failure that Toyota is aware of and should RECALL!!! I lost braking with my 10 year old son in the car and could have DIED!!!! Car has 62,000 miles on it! Ridiculous. Over 4,000$ to repair I’m being told. This is a significant Safety issue and you should make Toyota recall it!

The ABS system has malfunctioned. It shows "ABS", "Brake" and "Hillside assistance" lights on the dashboard. Have to push the brake pedal till the end for applying the brakes. This is causing a safety issue. Toyota knew about these brake issues as they have a Support program to replace these faulty parts with another part. The Support program is 20TE07 which is expired. Instead of considering this as a support program, they should be considering this as a recall. This is a safety issue as the ABS stops working at anytime.

Driving approx 35 MPH. Traction, Brake, ABS lights all illuminated. Went to brake and brakes went almost to floor with little to no braking power. Car felt out of control and unreactive. Slowed down, pumped brakes (brakes worked but not normal) and pulled over. It was extremely scary and happened out of the blue with no warning, I thought I was going to crash as car felt "slippery" and unresponsive/no braking. If there was a red light or someone stopped in front of me, I would have crashed. Tested and found code of C1391 ABS Anti-lock Brake System Abnormal Leak of ACC PRESS. Researched and found customer bulletin from Toyota POL18-03 and Customer Support Program ZJB. Safety at risk - near accident, could have been a huge accident, no warning and no brakes. This should be a recall! No warning lights prior to failure, lit at time of failure. I was completely unaware of the potential brake failures. Toyota should issue a recall or cover repair. I have been tossed back and forth between corporate & local dealer. Customer coverage expired June 29, 2022 for my car (10 yrs after 1st use). The incident occurred barely one month later on August 16, 2022. It is under 150,000 miles. Toyota refusing to assist or take responsibility for repair coverage. I have been given the runaround by Toyota and attempting to get a call from a case manager is near fruitless. One case manager left me a voicemail indicating that they cannot help me until I take the car to a local dealership to diagnose. So I did. Forced to Toyota, we carefully drove on side streets to the dealership only to be charged $130 for diagnosis & attempt to "upsell" extra services. Vehicle inspected by Toyota. C1391 replace brake booster assembly master cylinder and brake pump almost $3,000. We drove home white-knuckled. After many more phone calls and unable to speak to a case manager, I rec'd a voicemail indicating they will not cover due to expired June 29, 2022. Same issue happening w/other models - pls recall.

I was driving on freeway when my vehicle shut off and wouldnt start again. It almost caused an accident thankfully not. I paid to have car taken tothe repair shop Viva Toyota in Las Cruces NM and they inspected it and gave me a quote on repair as well what was causing the problem. There was a saftey recall for the PCU and i believe the inverter is causing the failure. please help me to get this figured out.

I was driving my 2012 Prius on the highway at around 55 MPH. The Hybrid System Warning came on and the car lost all power and immediately began to coast. I was fortunate not to have been in or caused an accident but cars behind me had to swerve to avoid hitting me. I was able to coast to a middle median lane. After waiting 15-20 minutes, the car never regained power. We were finally able to push it off the road and into a parking lot. It never regained power.

Seven days ago, the hazard lights on our 2012 Prius suddenly would not turn off. By the time we got home, the brake, ABS, and the traction warning lights all came on. Two hours later, the hazard lights stopped blinking but the other lights were still on. We brought the car into the Toyota dealer for service the next morning (8/1/2022) to have the issue checked, notified the service writer of the hazard light being the initial issue. Mechanic cleared the codes and the lights all were off and stayed off after what he said was 2 test drives. We asked him if the mechanic had tested the hazards, to be sure they didn't stay on. He said the mechanic had left and we agreed to leave the car overnight so he could check that again. The service writer gave us a list of other repairs/maintenance we should have done but none of them was the brake booster acuator. We declined the other service and went home. Car drove fine. Yesterday morning, we woke up to see the hazard lights flashing, even though we hadn't egnaged them since the previous Sunday. Our neighbor noted he noticed them flashing at 2 am. We brought the car back to the dealer and when my husband spoke directly with the manager, he (manager) said that they weren't aware of the hazards flashing. That is a lie. I told the service writer when it was brought in and then we discussed it again that afternoon. Manager calls us late yesterday to say that we need to replace the brake booster acuator at the tune of $3400+. The manager told us this morning that Toyota had a recall on it but they weren't notifying people unless the issue occurred. He said there was recall coverage, which Toyota extended, but it expired 7/24/2022. We never received any mail or email notification of a recall and have only had our car serviced at this dealer. Why did they not warn people? We are outraged and livid. How is this kind of greedy chicanery allowed?

In July of 2021 the Toyota dealership replaced the inverter on my 2012 Prius V. At the time, it also was exhibiting signs of the brake booster and pump failure as outlined in CSP 20TE07 (see https://www.toyoheadquarters.com/threads/2012-2014-toyota-prius-v-2015-toyota-prius-v-coverage-for-brake-booster-and-brake-booster-pump-assemblies-csp-20te07.2116/). It was inside the extended warranty period, but they would not fix it at the time, because it was not throwing diagnostic codes. Subsequently, the braking system malfunctioned, nearly causing a high-speed accident on the freeway. With diagnostic lights now showing, and code C1391 stored in the OBD system, I took the car back to the dealer, but now they said it was past the 10 year limit and still would do nothing about it. This is not acceptable! They knew the brake system was failing and a safety hazard, but would not address it, just because it hadn't actually failed yet. Toyota needs to further extend the warranty and take care of this brake failure past 10 years and 150,000 miles. Just because I took good care of my car and the brakes didn't fail as early as other owners, I should not have been subjected to the risk of brake failure or the high cost of repairing the brake system when Toyota took care of this problem for so many other hybrid owners. Please help.

Running errands and when I got back to my Toyota prius v many lights were illuminated including my brakes abs tire pressure traction lights were all on. Tool my car to dealer for them to gladly request $5,000 to repair this. Dealership told me "the repairs are going to be a new master cylinder + new brake booster pump + fluids as needed for repairs" . This is a known issue for 2012 to I believe 2014 prius model V. This is a huge safety issue and a manufacture error This should be recalled and covered by Toyota as shouldn't be any fault of my own. On today's world 5k is a crazy amount of money to fix a known issue thay could arise again. Toyota needs to do better to protect their customers. Shame on them.

2012 priusV has intermittent vsc and traction control when cornering left or right at slow speeds, as less than about 20mph, 5-20. This is happening on dry road conditions at unpredictable times. The vehicle may deceleration and have a lungeing behavior with traction and or bracking interrupted momentarily. On accelerating from stop sign turning left or right the vehicle may pause accelerating briefly and pull with the abs brake auto/ intermittently applied.The traction control light may or may not illuminate at the short time interval of these events, but traction control light does not stay illuminated after the event is over. No error code is read from the vehicle with error code reader. These events are very startling and cause sometimes cause the vehicle to speed up or slow down abruptly. These events are happening at low speeds, however with the car surging forward or abruptly slowing on corning and lane changes there is potential issues of keeping the vehicle under proper control at these times. I believe Toyota should correct this problem so that it never occurs. Toyota to Find a solution an implement a recall to update vehicle.

The headlights are not functioning properly as a result of severe discoloration of the lens material. This creates unsafe driving conditions at night since the road is not properly illuminated, especially in areas with inadequate street lighting.

Faulty brake booster pump

ABS system has malfunctioned- brakes lose pressure constantly (makes a barking noise when pressing on them or holding them down), and brakes feel very squishy. Car constantly makes whirring noise of actuator pump trying to function. Mechanic said on inspection that it was the abs actuator and potentially the master cylinder as well. Vehicle is unsafe to drive

I have the same issue as every other Toyota Prius owner. My car has 177,000 miles and Toyota quoted me $3200.00 to replace ABS system that causes Brake Failure and risk of Crashing. All the ABS lights come on and the car almost loses all braking power.
