2012 Toyota Prius V Complaints

I am reporting a sudden and dangerous failure of the brake booster in my 2012 Toyota Prius. While driving, I experienced a loss of braking power, accompanied by several warning lights including ABS, Brake, and the Traction Control system. The brake pedal became extremely stiff and unresponsive, significantly increasing the stopping distance. This failure nearly caused an accident, as I was unable to stop quickly enough when traffic slowed unexpectedly. This issue happened without warning and is a serious safety risk. I later discovered this is a common and widely reported defect in 2010–2015 Toyota Prius models. Toyota issued an extended warranty (Customer Support Program ZE3) to cover this known brake booster defect — but only for vehicles within 10 years or 150,000 miles. While my Prius has well under 150,000 miles, it is just over 10 years old, which disqualifies me from coverage, leaving me with a repair estimate over $4,000 for a well-documented manufacturer defect. This seems g...

This Prius Hybrid is my [XXX] mother's car which she got thinking is was a very safe and reliable vehicle. She purchased the vehicle from a Toyota dealership here in Maine on [XXX]. Last week while driving down the road, all of a sudden, every brake warning light lit up the dashboard and the brakes became extremely unresponsive. It scared us both to death but thank goodness, I was driving when this happened. After doing some research, I have discovered that this a very well known brake issue with the 2010-2015 Prius cars. I cannot for the life of me understand how this major safety defect has not been made into an actual safety recall. I did contact Toyota customer service and they will not help us at all. Even though my mother has only had the car for just under 9 years and is well under the allotted mileage, they said their Customer Support Program (ZJB) only covers 10 years from the day the car was first driven after production. Her Prius now is inoperable and the repair costs ar...

On three of the four tires at different times the tires were separating. They had bulges in the tire. Caused extreme vibration and noise. The last tire was today with 22k miles. The other two were a year ago with 15k miles. I’ve had to replace all 4 tires

The contact owns a 2012 Toyota Prius V. The contact stated that while driving at an undisclosed speed, the service brakes warning light illuminated. The vehicle was taken to the dealer, who diagnosed failures with the brake booster assembly and brake booster pump assembly. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Program: 21TE01. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

On 10-17-24 these warning lights came on: 1. Pre-collision System 2. Hybrid System 3. Airbag 4. Safety Connect red light And Intermittently: 1. Slip Indicator 2. Brake System Cruise control would not set, and displayed "E3". ------- Component failed: Dealer determined that the driver's side door harness had been chewed by a rat that had entered the under dash area "somehow". They said it couldn't be repaired but must be replaced. My insurance deductible was $500 and they paid the balance of the $1,387.06 bill. (I have retained the harness, which could have been repaired by splicing the two wires connecting to the driver's side airbag collision sensor. The labor to splice the wires would have been less than an hour.) ------ Safety: The chewed wire apparently disabled the Airbag, Pre Collision, Emergency Automatic Braking, Seatbelt Pre-Tensioning, ABS, and Stability Systems. ----- The dealer confirmed the problem. ----- My insurance adjuster did inspect the harness. ----- I placed elect...
