When stopping suddenly sometimes the brakes on my 2004 prius would not respond immediately as they should. They would release the calipers completely and the only way to stop would be to let off the brakes and press them again. It does not happen often but it is regular enough that this has always concerned me very much. Today i was following a car who slammed on their brakes very suddenly and therefor i also had to…

Brake actuator assembly malfunctioned, and had to be replaced, just as predicted in toyota's warranty enhancement zg1. Toyota knows the part is defective, but they refused to replace it until it failed, and mine did not fail until after the extended warranty deadline. This failure happened on i-45 near madisonville and i had to pull off the road because a warning light brake light went on.

When driving down the road all of a sudden we tried to use the brakes and it felt like we only had 10% of our braking ability. The brake light came on and abs light went on and the stability control light came on as well as a warning buzzer. It felt like we had manual brakes.

Bought car a few weeks ago and lights came on and brakes did t work. Very scary. Toyota dealer said i missed a warranty extension last year. Brake actuator problems they said. Very dangerous. Why is there no recall?

When i stepped on the breaks they did not react. I was going 65 miles an hour on the highway and thankfully we were not going down hill. I used the engine brake and pressed really hard on the breaks to bring the car to a stop…

Takata recall. My car's break lights went on, as well as the abs and vsc warning lights. Strange noises are coming from inside the hood of the car due to that. I also feel like my car does not break properly.

My prius suddenly had a 70 to80% loss of brake power. My parking brake light came on along with the abs, vcs, the red triangle and a load buzzer. If this had happened at highway speed i could have rear-ended or killed someone. After turning my car off and letting it sit the lights stayed off. This concerns me because it could lead to a false sense there's nothing wrong. I took my car to the dealer and they seemed to…

The brake actuator in my car, which is a known problem in these cars gave out as confirmed by both toyota and an independent mechanic shop. This is a very dangerous safety issue that could get easily cause an accident. It is unacceptable.

As i was going down a hill the abs vsc brake light came on and the brakes failed. The pedal became mush and i lost power braking. This caused me to almost hit the car in front of me. I swerved to the side of the road and pulled off the shoulder just missing the guard rail. I have found out that toyota knows about this faulty problem and now they dealership wants to charge 3,000 to fix it.

I was traveling on i95 when all the brake warning lights came on (abs, brake, etc.). I tried to slow down the car, but the brakes didn't seem to work. Finally, the regen system kicked in, and slowed the car. When i jammed my foot hard on the brake pedal, the car stopped with a jerk. This is not the first time this has happened. The first time it happened (when all the lights came on), i brought the car to the dealer…
