The car began to jerk, made knocking noises, miss fires on cylinder 1, 2 and 4, coolant leakages, oil leakages, compression issues and the check engine light keeps turning on and off. My safety has been put into play because, the car would jerk many of times as it would want to stop as I was driving. I would then have to pull over and call for assistance. Per the Toyota service advisor he recommended that I needed a new rebuilt engine kit. The extended warranty company stated that I was negligent with my car and denied my claim and refused to pay for the 10 grand motor and I had to tow my car to another shop. However, the car at this time is still experiencing the same malfunctions. The warning lamps are still showing at this present time and prior to the failure of problem. This car meets the "Lemon law guidelines, However, I have been informed otherwise that I don't meet the criteria for lemon law due it being expired sometime last year in Oct of 2024. As stated this is a lemon car.

The Head Gasket failed on my vehicle, and began to burn coolant and overheat my engine. Upon description of the issue, a dealership mechanic was able to diagnose the issue. The sudden failure of my vehicle due to overheating while driving was extremely risky, and I had no indication that the issue was a head gasket until a dealership mechanic was able to look at my vehicle after being towed. I had taken my vehicle to a third-party mechanic, and they could not tell me why my vehicle was burning coolant, but provided a temporary Stop-Leak fix that did not hold. The first appearance of the Check Engine light was about 9 months ago, was assumed to be the spark plugs, which I had replaced, but then my coolant light started coming on with the check engine light for about a week before the engine overheat incident. The vehicle has been inspected by a Toyota Hybird Mechanic. No other inspections have been done. My safety and other's safety was put at-risk as my steering, speed control, and speed monitoring systems immediately shut off once the system detected an overheat, making it difficult to pull over safely and slowly to address the issue/call a tow truck. I required physical assistance from another motorist to move my vehicle off the road to allow others to pass.

Brake Actuator Valve Wear all lights relating to brakes are on, Dec. 12th 2024. The warranty for this expensive fix ended March, 2024 or 150k miles, there are only 106k miles on the vehicle. Something that is such a safety hazard SHOULD not have a date. We are experiencing unexpected loss of brake power while driving, accompanied by multiple dashboard warning lights, so we are unable to drive to the Toyota Dealership to have it scanned for issues. Toyota has advised us NOT to drive the vehicle, and we live 40 min from the nearest dealership. We bought the car from a Toyota dealership used, and they should have fixed this before selling the vehicle. Complete negligence and a huge safety issue. We only ask that they warranty be extended for the entire year of Dec. so that we can get this fixed asap.

Brake light and several other lights suddenly came on. The brakes became spongy. Taken to a repair place close enough for walking for diagnostic work. It showed that the brake booster needs to be replaced. There was a campaign for this problem, so Toyota knows that it is/was a problem. That campaign has apparently ended. This is a very expensive repair on a car that I expected to use the rest of my life. There was no warning by the dealership from which I purchased the car that this was a possible pending problem.

Car was diagnosed at a Toyota dealership with a brake booster issue reading code 20TE07 after my vehicles brakes suddenly would not work and the car continued to jolt forward. The brakes wouldn’t stop the car. According to Toyota, my vehicle is three months outside of the warranty period but under the covered mileage so we are left to repair this defect ourselves. This was a very dangerous situation and could have cost us and our children our lives instead of just the $4800 repair cost. This has happened to both of our Prius’s so this is not a rare issue. Toyota needs to have a plan for these parts failing suddenly and they should all be recalled for safety in my opinion. The experience was very scary and we had zero control over the vehicle when the brakes suddenly went out. Where do I join the class action lawsuit?

Brake actuator failure, coded as C1391. known issue by Toyota which can result in loss of brakes if not repaired. symptoms of problem: pulsing air sound from master brake cylinder, and/or all braking system lights illuminate on dash.

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.

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.
