Brake getting stuck on the floor would have to press on brake really hard just to get a response, this will happen out of the blue! Driving in highway or just driving off the driveway. I almost hit a car in front of me due to lack of brake, i had to swerve to the side! First appear 1 day after buying the car..This issue needs to be worked on right away.

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.
ABS Actuator and Booster Assembly failing. No recall was issued but a safety bulletin to the dealer with a cutoff date and nothing issued to consumer to know it needs to be replaced. Now I am outside their service bulleting window with a 3,000 repair that should be covered indefinitely by toyota
I have never received a recall mail regarding the car. I used an insurance tracking plugin, and all the problems started.pcs error message on my dashboard, due to a leak in brake booster they said. My dealership will not tell me it's a recall, made it seem like they helped me instead of charging as high as $4000. I was not given a loaner car for the 4days they had my car, and did not get any refunds for the rental car I got
The problem started with a chirping noise when the brake pedal is depressed. Today the car appears to lose regenerative braking charging. The vehicle stability control and ABS light and brake light came on. The brake appeared to be mushied.
Problem with braking system involving, the other day the car was on and suddenly three (3) warning lights came on: brake light, ABS light and traction control light. There is also now a pumping sound coming from under the interior of the dash (on it at least sounds that is where it's coming from. The car has 151,428 miles on it. I've included pictures of the current eror code, mileage and dash lights that are on.
My prius was just fine then one day it stalled while I was driving in the middle of the free way. I took my vehicle in to elmore toyota in westminster, ca, they found it had a failed inverter and it was still covered under warranty. It took 2 weeks for them to fix it, but when they returned my car, the slip indicator was now on and would not turn off. They claim it was like that prior to the failed inverter, this was false, my car was running perfect. They then wanted to charge me nearly $1k to fix a problem I did not have prior to failed inverter. I feel the situation was connected but they refuse to cover it.
Vehicle stability control, anti-lock brake, and traction control lights intermittently turn off. A few times it shut down the hybrid system and tell me to stop . Now all those lights are all on and I am driving without vss, ABS and traction control. Braking is getting harder. I took it to the dealer and they told me the cost is $3500. I did some research and found out that this is a known prius problem problem
