2014 TOYOTA PRIUS Complaints

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.

Brakes failed to stop vehicle for over almost ½ of a block. The driver, a young woman, was so terrified that she is refusing to drive the car even after the brakes have been repaired. It is my understanding that Toyota is aware of this problem and has issued directives for its dealers to make the necessary repairs. However, I was told that this was extended to 150,000 miles or 10 years from first in service date. I am including the invoice from Lipton Toyota for over $4,000 and I am respectfully requesting that Toyota makes this right and refunds this money. The failure of a braking system represents a critical life threatening situation of which no one can deniy.

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.

I have a 2014 Toyota Prius V. I was driving down the highway at 55 m/h when my brakes became spongy all of a sudden and the ABS, traction and brake lights came on the dashboard. I was very scared and seeing that my brakes were failing I almost caused an accident that could have cost my life and my family's. I managed to get home safely and after scanning the system got the code C1391 - ABORMAL LEAK IN ACCUMULATOR. I did some research and this defect is so well known that Toyota launched a costumer program to replace the booster for free. I took it to a Toyota dealership and they wont't replace it though because the program expired a couple of months ago. This is an expensive and life-threatening part. The defect comes from the manufacturing facility, not from usage, so Toyota should be responsible for it.

I am a US military member stationed in Germany. I bought my Toyota Prius V used, in 2020, knowing I'd be stationed in Europe and expressly because of Toyotas reliability and Prius's great mileage. This was our family's third Prius and a sixth Toyota vehicle. It's been almost exactly 2 years since my family moved to Germany, when one day I was driving through a small town, below the speed limit of 35 mph (50 km/h). Suddenly, while driving, the red BRAKE light, yellow ABS light, and red brake system warning lights came on all at once. The car's brake continued to work normally but I also started hearing a low volume, frequent, 1-sec long electronic buzzing sound coming from somewhere the front of the car, on the driver's side. It was audible every 3 seconds or so, even after the car was put in Park and turned off, then it went off after a couple minutes. I took the car to a local German Toyota leadership to have the problem diagnosed. The Service Department told me later that day the DTC1391 was identified, and the brake booster assembly + brake booster pump assembly needed to be replaced, at a total cost of this repair being over EUR 9,000 (around $9,900). The parts themselves were quoted to cost EUR 3,500 and EUR 4,000 each, and would have to be ordered from the US. I cannot afford to pay $10K to repair a 10-year old car. After some research, I discovered while Toyota never issued a recall, they knew about this brakes problem since 2018. I found several "Customer Support Program" notifications to Prius owners for this specific problem, including the one numbered 20TE07 which applied to 2012-2015 Prius's V. It told dealers to do this repair free of charge and extended the coverage for 10 years or 150,000 miles It also had info on repair cost reimbursement to customers. Hoping I could get my car fixed and file for reimbursement I called Toyota US and was told this CSP expired in Mar 2024 for my VIN and that there was nothing Toyota would be able to do.

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.
