2014 Toyota Prius complaints

Got code C1391, a common issue with the Prius. Brake Booster Assembly is defective due in no part to owner/driver of vehicle. This creates a serious safety issue with braking. Traction control light, brake light, and ABC light are all on and repair is ridiculously expensive.

I started noticing the ghosting or tripling of light issue in my windshield. I mostly noticed this during night times, I initially thought I was just tired and my eyes were tired, but I’ve been able to photograph it and verify my experience with other people. This effect is horrible for my eyesight and makes all lights at night so blurry I cannot drive safely.

Apparently there is a known defect on the brake actuator/master cylinder/booster on the 2014 Prius that would have been addressed if the car had been driven for less than 10 years or 150,000 miles. We purchased our car in April 2014 and the part just failed yesterday at only 126,000 miles. We understand that there is a pending class action suit (or perhaps one that was settled) but do not know how to become a member of it. It seems as if they knew that the part was defective, but did not offer to do a voluntary recall and remediate this before a failure, they should have, but instead, now we have a $3400 repair bill. Requesting assistance in evaluating whether there was negligence and or liability for them not addressing this issue in a timely manner.

Yesterday, while driving on the interstate, all of the brake related warning lights on my dashboard lit up- ABS, traction control, brake, caution)- causing me concern, so I looked for the next exit. While exiting and slowing, I noticed my brakes felt different and were not as responsive as usual. I called my mechanic and cautiously headed to his shop a couple of miles away. Today, I met with him and found out that there is a leak in the brake booster line, but the extent of the problem is yet to be determined. I immediately did an internet search for my model year and found that there was a safety campaign on other Toyota hybrids for that year, so I called the Toyota customer service number. I was told that my vehicle had an extended warranty for the brake booster, but it expired 9 months prior, 10 years post purchase, The rep has escalated my issue but I will have to wait to see if someone with more authority can potentially give me an additional extension. Meanwhile, my car is not drivable, as the brakes could fail at any moment. In my estimation, this should not be a time limited coverage, but an actual recall covered by Toyota. This is not normal brake pad rotor wear and tear, but a known issue with the assembly system and a true safety hazard that one cannot foresee without experiencing minor to catastrophic failure of the system.

The brake master cylinder and brake booster failed. It is available for inspection upon request. My safety was put at risk as braking distance increased significantly. The problem has not yet been confirmed by a dealer or independent service center. The vehicle has not yet been inspected. The warning lights appeared upon failure. Brake warning light, traction control light, and ABS light appeared. Prior to complete failure, the brake booster would cycle on after opening the door and would then cycle every few seconds for 10 minutes or so after parking.

Something felt wrong with the brakes for many years, but mechanics checked the brake pads and rotors and said they were fine on multiple service visits. I had multiple close calls during quick stops on highways, I though I just needed new tires. I then started to hear a whirring buzz noise become more and more frequent. I researched what it was and found on reddit that there was customer support program ZJB to repair failed brake accumulators, which affects hundreds of thousands of these cars. The problem was that my brakes were only in the process of failing rather than being fully failed enough to send codes and light up the dashboard, which is the only way the customer support program would cover the $4,000 repair. The failure finally happened when I was three hours from home and had half the braking power as usual and had to limp the car home for fear of the brakes going completely out. I can't believe Toyota is letting this many people drive around with a potentially catastrophic brake issue.

I was driving on the highway during rush hour when a loud beeping noice began. My 15 year old cousin was in the passenger seat and began to check for the source of the beeping. I was driving 55mph on a busy highway with no safe shoulder stop. As I was preparing for the exit, the brakes suddenly became dysfunctional. The pedal was extremely hard to press down and I found myself unable to slow down the car in enough time to avoid hitting upcoming traffic. I found myself in an urgent, life threatening situation and needed to pull over into the emergency lane located before the exit. I could not just consider my safety, but that of other drivers and my 15 year old passenger. She is traumatized. I was able to get the car to stop with my entire weight on the pedal. Once stopped, I scrambled to find the reason for the sudden brake problem, checking if anything rolled under my foot, if the floor mat was loose, if the gear shift was wrong, even checked if I accidentally hit the emergency brake. Nothing was out of place. No new dash lights. I looked in the manual. I had no information. I went to jiffy lube and they performed a diagnostic test and informed me they are unable see all the codes with hybrids because Toyota’s computer can only see Just in August I went to Toyota for my oil change, nothing was said about the brakes needing to be fixed and how repairing them now would prevent the failure of the accumulator pump system. If I had known paying $400-$500 for the brakes then would

Without warning, my brakes completely stopped working and I was fortunate enough to be somewhere I was able to pull over without being killed. Toyota is aware of this issue, but put a 10 year timeline on the complementary repair, which is totally unacceptable, as owners were not notified directly about this program, therefore how could we know it existed, was a problem, and to go get it fixed within their arbitrary deadline? I could have died losing brakes on the freeway, or even could have killed or injured others. This is a known, and severe safety hazard, and Toyota is not taking responsibility. It is unconscionable. Hoping for a class action lawsuit. It was a $5500 repair in California, which was almost the value of the car. Absolutely brutal and horrendous business practices from this company. Shame on them. I hope this agency NHTSA will add this report to the pile of others who have reported this, and actually take meaningful action for those of us who have been put at risk, and ripped off in the process.

My 2014 prius experienced a failing brake booster actuator assembly. I was driving when suddenly my traction control light came on and my brake pedal turned mushy. I pulled over to a parking lot and put my vehicle in park. As soon as I did this, the ABS and parking brake light both turned on. I had the vehicle towed to the Toyota dealership. They diagnosed the problem as an internal leak in the brake booster actuator assembly. This is a common problem with these vehicles, but instead of Toyota issuing a recall, they only did an extended warranty coverage of which my prius didn't fit the parameters. Now I am stuck with a vehicle that is unsafe to drive and a repair estimate of $3,900 because of one of their parts failing. This should clearly have been made a recall with the volume of prius owners experiencing this problem. What a disappointment after having 3 Toyotas for many years.

On [XXX] my brakes failed while driving, (brake booster and actuator) moving at 25 mph, all of a sudden lights ABS and brakes indicator light started flashing and beep. I was approaching a yellow light and attempting to slow down, my foot went to to floor and the were NO BRAKES. I used the EMG brake slow down me pulled into an empty parking lot. My vehicle is available for inspection at request. My safety was was put at risk due to having no control and coming very close to crashing into another car putting that driver at risks as well, but was blessed I was able to avoid an accident. This problem has been confirmed by Phillips Toyota in Leesburg FL #(352)728-3020. The vehicle components have not been inspected by others besides the dealer. I am 2 months over the 10yr customer support program at 102k miles. I have been complaining for the past YEAR to the dealer regarding strange noises like chirping, air deflating when pressing brakes, constant buzzing sounds from system even when car is off, and being propelled forward when going over gravel or railroad track surfaces of the ABS light goes on. This is on record and each time I’d ask, they’d mention it is the brake booster going but because there was no indicator lights or code coming up, they were unable to do anything. My last service in may 2024, I requested a diagnostic on the brake system, which I paid extra for, knowing the 10yr program was about to be expired in July. The dealer found no codes and assured me it was sa

The braking system is failing with the following codes I tested with the BlueDriver scanner.

This puts the drivers, myself and fiance, at risk of catastrophic collision in the event that the brakes fail while driving. I will call Toyota to obtain a replacement of the system that has occurred with many other drivers. The vehicle has not been inspected by manufacturer yet but it is important to know that this is a serious problem that could kill people. The problem was identified when warning lights came up on the dashboard but there is also a sound coming from the brake actuator that shows a problem. The problem is due to manufacturer error, I have driven the vehicle normally.

So my wife is pulling into our driveway with my little ones and notices the ABS, traction control and Brake light come on. I then had the vehicle looked at by a local Toyota dealership and they tell me I'm getting code C1391 and that it's a known issue. They then tell me I'm out of my extended customer support warranty time frame and I will have to pay. According to NHTSA this is a known defect on this vehicle and it affects more than 100k Toyota Prius vehicles. So basically, we've been driving around in a vehicle that the brakes may fail at any moment and potentially kill us all but is only addressed by the manufacturer when the known failure occurs. Even then, they only address it if the error occurs during their set time frame. It seems this has been brought to NHTSA's attention on a few occasions and nothing has been done. I would think brakes are something that warrants a recall on a known defect. Thankfully my wife and kids weren't doing 70mph down the highway when the brakes all of the sudden stopped working.

The contact owns a 2014 Toyota Prius. The contact stated while driving at an undisclosed speed, the brake pedal was depressed with several unknown warning lights illuminated. The vehicle was towed to the dealer to be diagnosed. The contact was informed that the brake master cylinder and the brake booster pump assembly had failed and needed to be replaced. The manufacturer was not made aware of the failure. The failure mileage was approximately 82,000.

This vehicle lost braking assist while in motion on a well known problem from TOYOTA. There has been class action lawsuits on this very fact. Toyota issued a customer service warranty for vehicles that have less than 150,000 and filed before March 2024! My car has 127k and failure was Sept 9 out of the warranty. I understand that there is a line if the sand however this needs to be a recall as it effects so many vehicles and it is dangerous! I am asking you urge them to make a recall for this! I have paid for this repair and am furious but I had to do it!

ABS actuator failed in April of 2023 after more than a year of constant whirling, which my mechanic didn't diagnose until after my dashboard lit up with errors. The issue was diagnosed by AAA mechanics after the dashboard warning lights lit up, with a $4,000 cost to repair. Brakes are spongy, car is rarely driven at this time. We were told that the brakes would continue to work, but the ABS system would not. Now the vehicle beeps constantly when driving, which appears to mean the brakes could fully fail at any time. Based on subsequent research, Toyota was quietly fixing the ABS acuator issue until last year, but it was not offered when my vehicle was brought in last year during another recall. When it failed the car was under 10 years and 150K.

My car started exhibiting signs of a known brake booster/brake systems failure for Priuses in the 2010-2015 range. These include the ABS, brake system, and skid/traction lights coming on and a 3-5 cycling whirring noise. The brake sensitivity is also altered. This happened suddenly today. I checked the battery voltage (normal), so this is not causing the issue. After investigating online, I have discovered that many consumers have experienced the same issue and are being denied a recall/repair coverage by Toyota. Today, I am reaching out to Toyota to see if the replacement/repair, which should be in the range of $3-4k will be covered by Toyota. According to numerous other Prius owners online, this issue is being denied by Toyota for coverage, even though it is something they are fully aware of. This is unacceptable and dangerous on their part. My vehicle has 110k miles, was leased used last year, and has not had any issues otherwise. I am up to date with all routine maintenance, including getting my pads replaced and rotors maintained last year as well as new tires.

Brake warning lights illuminated and loud beeping for the first time. Took the car to local repair shop who advised me to take it to the dealership. Dealership indicates that R&R Brake Booster assembly with master cylinder and brake booster pump assembly need to be replaced at over $3100 and brakes are at risk of failure. I researched and found the NHTSA Customer Support Bulletin - [XXX] indicating this known issue. The support period expired in March and mileage has now exceeded the limit for support. Though I have had the car in the dealership for service many times, this was never brought to my attention. The dealership advised me to contact Toyota. Toyota then advised me to contact NHTSA about the problem. Further research indicates ongoing problems with this issue that have not been resolved - [XXX] should have issued a recall for this important safety issue.

Brake Booster Assembly in my 2014 Toyota Prius began cycling more often than usual in December 2023. By March 2024 it began cycling approximately every 30 seconds. Randomly while stopped or parked, there would be four warning lights illuminated on the dash - SLIP indicator, both Brake System Warning Lights - the word "Brake" and the "((!))", and ABS Warning Light. By June 2024, I would also randomly lose stopping power & a great distance was necessary to stop the vehicle. I took the Prius into my local Toyota Service Center where it was recommended both the Brake Booster Pump and Brake Booster Actuator be replaced. When I brought up Toyota's Customer Support Program for which my Prius is eligible in terms of age, mileage, and symptoms, I was told a DTC is required to verify the issue. According to this local Toyota dealership, the Master Tech confirming the issue and recommending replacement is not sufficient. Since the lights were illuminated, I asked why there was no stored DTC. They responded "Well, I'm not sure" and continued to reference the required DTC. This brake assembly is an issue that Toyota has acknowledged, but fails to accept full responsibility by issuing a recall. This gross negligence by a vehicle manufacturer.

The contact owns a 2014 Toyota Prius. The contact stated that while driving at an undisclosed speed and attempting to stop the vehicle, the brake pedal was stiff and would not depress easily, requiring exhaustive effort to depress and bring the vehicle to a complete stop. The brake, traction control, and ABS warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a brake booster and brake pump assembly failure. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 116,000. The VIN was not available.

I lost the brakes. The Brake actuator failed. I was able to swerve around traffic to avoid a collision and get the car towed home. No warning lamps until it failed. The brake actuator was replaced and I saved the old, defective component.

The brake booster and master cylinder failed on my Prius. The diagnostic code is C1391 Abnormal leakage in accumulator, which is a code covered by Toyota’s prior recall on this vehicle.

Drove car to work one morning and it was VERY difficult to brake almost causing an accident. Brought it into the Toyota shop and they said this code came up: DTC code C1391: Abnormal leak of accumulator pressure ,recommending to replace brake booster and brake booster pump assembly internal malfunction of components.The necessity of its routine replacement is vital as an old or malfunctioning unit leads to decreased braking performance and ultimately brake failure. They told me that there was a program offered to customers where they would replace this known issue, but I'm 2 months outside of this so the issue is no longer covered under Toyota. The fact that this is a known issue that Toyota does not want to recall is ridiculous and now they want customers to pay for it.

2014 Toyota Prius: While driving at high speed the engine stalled unexpectedly, steering and braking were not effected. Was able to safely coast to a stop in the breakdown lane and after a few minutes, restart the engine and proceed driving. Another event occurred on the entrance ramp onto an interstate highway. I was able to pull over safely and the car restarted after a short delay. This seems to be a very dangerous condition. Toyota dealer service said they could not determine the cause and they know of no recall. I found online a reference to NHTSA Recall # 20V369000 that referred to "unexpected hybrid power system shut down." That is what happened to me.

Noticed a whirring/hydraulic sound that occurred every 5-10 seconds. Could only hear sound if no music was playing and not driving at highway speeds. Sound was noticeable upon parking or exiting vehicle. Only noticed sound because it occurred more frequently than usual. Spouse who is hard of hearing could not hear sound at all. My understanding of sound was that it was normal for vehicle, however, within the time span of approximately 2 weeks, sound became more frequent. Researched noise, and found it was the brake booster assembly pressurizing. Took vehicle to dealership to have it confirmed. Per dealership "Accumulator inside brake booster has internal leak causing accumulator to constantly run." Brakes did not show signs of loss of function and there was no indicator lights on dash to warn me of problem with vehicle. When I inquired with dealership of how much longer they would last, they informed me they could not say, and that it was likely they could go out at any time. Called Toyota Customer support to see if they could provide any assistance. They stated a support program had been issued back in 2021, but is now expired. According to support program 21TE01, Toyota was willing to replace brake boosters that had already failed and could be confirmed with diagnostic code. However, as the part had not failed or showed signs of failure at that time, vehicle would not have qualified, and it was prior to current ownership. Owners should not have to wait for their brakes to f

We were on the interstate when suddenly our cruise control stopped working. We then noticed several lights on the dashboard lit up, related to traction control, brakes, and ABS system. We could still use the car brakes, but it took more pressure than usual to engage the brakes. We pulled over to an auto parts store, but they stated there were no ODB codes logged. After researching online, I suspected a brake booster failure as described in Toyota's Customer Support Bulletin ZJB. At my earliest convenience, I brought the car in to a Toyota dealership, who confirmed that the brake booster and master cylinder were failing and needed to be replaced. Thankfully, the brakes did not fail outright, but the situation could have ended much worse. I understand by reading online that this is not an isolated incident. I encourage this issue be more thoroughly investigated so that a proper recall can be issued if needed, to bring this to the attention of other drivers of affected vehicles.

Error code P0A94 Inverter/converter came and message to pull over. 9 yr 6 months.103365 miles. Toyota has this issue but never did a recall on my vehicle.

Code C1391 - Abnormal Leak in Accumulator. Accumulator for the brake pump is not holding pressure so the pump has to keep turning on to refill. Brake pump and ABS unit have to be replaced. In emergency situations, a malfunctioning ABS module leads to increased stopping distances and loss of steering control during hard braking. Lastly, tires can be worn more easily, which could lead to tire blowouts. This puts myself and others at risk for deadly consequences due to an increased chance for collision if I am unable to control or stop my car. This problem has been confirmed by Toyota and multiple years of Toyota vehicles have had their brake actuator assembly warranty enhanced. The warranty enhancement program has secondary coverage, which is applicable for 10 years from the first date of use, or 150,000 miles, whichever occurs first. Currently I meet the 10 year requirement but have 162,000 miles on my prius, which is completely frustrating. Many have posted with the same problem of being just outside the warranty. The vehicle has been inspected at a Toyota dealership. A symptom was noticeable starting from over 1 ½ years ago when I was under 150,000 miles. The car produced clicking sounds when the brake pedal was held down at traffic lights. Once released, the clicking sound would stop. I spoke with a Toyota mechanic and he told me it was an issue with the brake pump and ABS unit, but Toyota would not repair it until it completely failed. He also mentioned that there was cove

I was dropping my daughter off at school and the car completely shut down on me and turned off in the middle of an intersection. I have just had brakes and oil changed but ever since I got the car codes keep popping up and when checked it’s all good. Front lights keep glitching and even with new brakes there is still a bad sound. My dash computer thing keeps going in and out. It happens a lot more when it rains and makes a sizzling sound I’m afraid to drive it in the rain. I’m besides myself how the car turned off on me and my child we couldn’t move I could accelerate and we almost got hit then another light came on and I couldn’t even turn my wheel. Very dangerous

The brakes have not failed yet, but there is a known issue with the brake booster on my model year. I would like to have the government force Toyota to guarantee the brakes for a longer period of time. currently Toyota has extended the warranty out 10 years / 150k miles from date of first use. Since these cars last so long, this should be 20 years / 300k miles from date of first use.

The ABS and traction control system in my 2014 Toyota Prius 4 are not functioning. They ABS light an the traction control lights are both on. I work in the automotive industry and I used a code reader to pull the codes and got a C1391 which is a brake booster and brake booster pump. That means either the brake booster has failed or the master cylinder is leaking. I contacted Gosche Toyota in Hemet and after waiting for a service writer to contact me (which they never did) I called 5 times till I finally got someone on the phone. They were very familiar with the problem. The problem is so common that SOME vehicles have been recalled. But for others like mine only a "Customer Support Program" was made. That program covers repair "if the parts are available" only for 10 years or 150,000 miles whichever comes first. But for someone like myself who has 170,000 miles Toyota says there's nothing they can do. The cost for me to repair it is $4800. The customer support program bulletin "ZJB" even says that service writers are not allowed to tell customers about the problem or the customer support program. That way when the car doesn't meet the requirements, they won't be responsible for the repairs, even though they know it will eventually fail. There is a lawsuit somewhere regarding this very same problem but for me, I'm screwed. I depend on my car to make money and now me and my family are out of a car. This is a known defect and a safety concern. Toyota is okay with leaving us with

BRAKES ARE NOT WOKING AT FULL SPECIFICATION DUE TO BRAKE ACCUMILATOR HAVING AN INTERNAL LEAK C1391

After I started my car and began driving away from a shopping center, I noticed that there were 3 static warning lights on the dashboard that had not been there before. They were the slip indicator light, the brake light, and the ABS light. I also heard a short, repeating buzzing sound coming from the front of the car that I had never heard before. As I was driving, the brake suddenly felt loose. Luckily, this happened as I was pulling out of a shopping center parking lot, so I was able to pull over to the side of the road instead of getting on the highway, which I was about to do. The following day, a Toyota dealer indicated that the issue was the brake booster pump/actuator system and that my car returned with error code C1391. The dealer indicated that this is a known problem with Priuses within my year range. I was told that I would have to replace both the pump and actuator. After talking to the dealer, I realized that there had been subtle clues of this problem beforehand. In the few months leading up to this incident, sometimes if I hit a big bump in the road, for a moment the Slip indicator light would flash and I would feel like I had no control of the car i.e. I was ever so briefly slipping. However, because this happened so briefly and when I hit a bump and everything went back to normal, I didn't think this was an actual problem, but now I believe this was an early sign of the brake failure. I contacted Toyota Corporate Office. They confirmed that this was an issu

The contact owns a 2014 Toyota Prius. The contact stated was unable to start the vehicle. Additionally, the hybrid system warning light was illuminated. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the inverter assembly to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 20V369000 (Hybrid Propulsion System). The manufacturer was informed of the failure and the contact was informed that the recall repair had been performed on August 20, 2020. The failure mileage was approximately 86,500.

At a stop light, when the light turned green, I took my foot off the brake and pressed the gas pedal but the car did not advance forward. Instead it was as though the car was in neutral and it began to roll backwards because I was on a slight slope. I attempted to get the car to move forward by engaging in shifter into Drive, but nothing changed (still as though it was in neutral). I heard a whirring sound but couldn’t tell where it was coming from. The only way I could get it to drive was to turn the car off and restart. This happened twice before I could get where I was going. Fortunately it didn’t result in an accident but I’m afraid to drive the car now.

Good Evening, I'm writing to request a callback in regards to my 2014 Toyota Prius which is subject to a recall. "The involved vehicles were designed to enter a failsafe driving mode in response to certain hybrid system faults. Toyota has found that in rare situations, the vehicle may not enter a failsafe driving mode as intended. If this occurs, the vehicle could lose power and stall. While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash." I recently just moved back to South Florida, I was living in NJ for a few years and had the Inverter malfunction earlier this February, 2023, forcing the car to enter the fail safe mode described giving me the warning to "Check Hybrid System, Stop the Vehicle in a Safe Place". The car was at Toyota Universe, Little Falls, NJ for about 45 days, since this was going to take the complete replacing of the inverter and an update of some sort of software. After receiving the car back around March 17th, I moved back to Florida about 2 weeks later. This evening around 5:30 returning from work, the car stalled again while I was driving surrounded by dense traffic, wouldn't accelerate with all lights flashing. Thankfully I was able to pull over slowly into a parking lot after which my steering wheel locked, and my car was no longer able to be put into Drive or Reverse. Car was only able to shift into Neutral and Park. This was the most terrifying experience of my

Was at Toyota dealership looking at 2023 Prius and 2023 Corolla Cross for daughter. I decided to leave and when I started backing up, my daughter noticed the Brake, ABS and Anti-Skid lights all came on at once. She asked if that was normal. It was not. A few minutes later, they stated flashing, then went out after I turned the car off. I live over an hour away and decided to drive it to Walmart, which is approximately 2 miles from the dealership and upon getting into the Walmart parking lot the lights started flashing again and upon applying the brakes, we heard a loud grinding sound. We didn’t think we were going to be able to stop! I immediately parked it and called my husband to tell him our horror story and to come pick us up. Our prayers were answered when he came and we were able to drive it slowly to the dealer. It was a cold rainy night to be on the road with braking issues. This is a very dangerous if not deadly situation! Shame on Toyota for not recalling this. How many lives have to be lost before you take ownership of your faulty hybrid braking system. We demand this be fixed for free regardless of mileage and be made a recall…NOT A CUSTOMER SUPPORT PROGRAM. RIDICULOUS!!! I don’t think our daughter wants a Toyota hybrid anymore…

I was in stop and go traffic. We got into a crash and my vehicle was totalled. I’ve never been in an accident before. It felt like the break system just broke down.

The car has oil consumption and over heat the try to fix it but no no one can d it so far

2014 TOYOTA PRIUS. CONSUMER WRITES IN REGARD TO HISSING SOUND COMING FROM BRAKES.

Passenger airbag indicator on/off light was on despite having passenger over the airbag activation weight requirement being present with seatbelt buckled. Brought car to Toyota dealership and after running diagnostics for two hours they found that the airbag itself is faulty.

My brakes completely stopped working while driving on a busy road. I took it to Toyota and they said it was my brake booster pump assembly. There is a known issue with the booster pump assembly and Toyota has a program to extend their warranty to fix this, but I was never once notified of this issue and never received any mail or notifications. They refuse to cover the repair because my mileage is out of warranty, despite the fact that this is an issue they caused and I almost wrecked and could’ve died. I was on a very busy road and my car was completely uncontrollable due to the brakes not responding. My passenger, others on the road, and myself could’ve died. The Toyota customer service representatives confirmed that this is part of the “customer service” program and it does not qualify due to it exceeding 150,000 miles. No warnings appeared on the dash until the brakes stopped working. The vehicle was inspected by Toyota and was confirmed to have said issue. This needs to be immediately recalled, I almost got into a very serious wreck.

Lost steering on car while driving. Shop noted right control arm completely corroded through and broken axle. Entire undercarriage rusted and corroded. Available for inspection. Sudden loss of steering is a risk factor for serious injury or death. Problem has been looked at by two independent service centers who have agreed on problem. Has not been inspected by manufacturer, whom I have contacted over 8 times regarding this issue, or by any other party. There were no warning signs or symptoms prior to failure.

The air temperature was probably about 50 or 60 F. On a route I routinely drive , I accelerated up hill normally from 0mph to about 45 to 55 mph. I did not accelerate aggressively. Just after climbing the short hill, The engine suddenly loses all power. I had to pull over. I look under the engine to find five pieces of metal blown out of the bottom of the engine block above the oil pan and oil spilling out onto the ground. The car has about 98,000 miles on it and was maintenance regularly including on schedule oil changes, coolant change, state inspections. There were no check engine lights or electronic error codes to indicate anything was wrong with the vehicle which I would have been able to diagnose and possibly fix. The car had been maintenanced in August/September for winter by myself. On the last maintenance, oil was discovered inside the engine air manifold and throttle body that had to be cleaned out and (The EGR was also moderately carbon clogged). I'm very dissatisfied with how Toyota handled my case. They called twice to ask when I wanted to schedule my next service appointment when they had the car sitting on their parking lot for three months. I also wrote them a detailed email similar to this report asking how Toyota could help and that I could not afford to buy another car. The engine failed and it can be inspected upon request. The vehicle had complete loss of power. The vehicle was towed to the nearest dealer. I have seen videos on youtube.com that show othe

My 2014 Toyota Prius was in a T-bone accident, directly on the driver door and the side air bags did not deploy.

Aloha! I got 3 lights lid up on a dashboard: traction control, abs and brakes. C1391 error is coming up on obd reader. I researched online and found that it’s a common issue , brake booster and actuator needs to be replaced. Many people having same problem. I found your website because of this YouTube video where many people found same problem: https://youtu.be/xA9jyrbZDWo

Airbags did not deploy when I got into an accident on I-91. The car has been totaled and is in Allstate's possession, and I believe it is available for inspection. My safety was put at risk because the airbags didn't deploy in a head-on collision with multiple objects (reflector pole, trees). The vehicle is in the process of being inspected by Allstate insurance representatives. There were no warning messages or symptoms prior to this incident.

Blizzard Pearl White paint started peeling off the car's body around the top areas of the 4 side doors (passenger & driver sides). There seems to be an active recall on this from Toyota for the same paint color and type, but the Prius model is not included in the active recall for this same condition. It has become a hazard such that such paint chips can be ingested by children. I took it to the Santa Monica, CA Toyota dealership and it was verified by the dealership representative there that this was a condition caused by a defect in the original paint with exposure to sunlight.

BRAKE BOASTER FAILURE. Dashboard lights illuminated: Brake, ABS and Traction. Brakes themselves felt spongy. Car felt very unsafe. I did find out that Toyota has a hidden Customer Support Program ZJB. However, the dealer found my diagnostic code to be c1202 and the Customer Support Program ZJB only supports repairs for codes c1391, c1252, c1256 or c1253. However, the exact same symptoms and safety issues were experienced and all the exact same warning lights also came on. The dealer’s diagnostics resulted in a $2,087 replacement of the brake booster. The dealer did contact the Toyota district manager along the way. He denied coverage based on the diagnostic codes reported BUT again I am arguing that my crazy expensive repair had the EXACT same symptoms, safety issues, and repair (e.g, brake booster replacement). The car clearly could not be driven. Note my Prius only has 92K miles. Attached is a picture of the dashboard warning lights that came on and the dealer invoice for the repair.

The contact owns a 2014 Toyota Prius. The contact stated that the seat belts would not lock properly. The vehicle was taken to a local mechanic where it was diagnosed with needing the buckles replaced. The manufacturer was informed of the failure and informed the contact that the VIN was not included in a recall. The failure mileage was approximately 88,000.

Brake being less effective to be spongy and keep losing pressure. The brake actuator constantly making boosting noise. Making driving unsure that the brake working even no warning light on yet.
