Service Brakes
This was not the first incident, but the most noticeable. When braking and coming to a stop, if the tires hit a pothole or any kind of hole or bump in the road, the vehicle accelerates suddenly. Today, it accelerated as i was braking and coming to stop at a red light. My back right tire went over a pothole, and the car jumped and accelerated about 10 feet. Luckily there was no car in front of me. *tr

While driving on a rough road surface and applying the brakes the car lost its brakes or the power to the brakes and surge forward. There was a feeling that the abs had engaged than disengaged leaving the car with no brakes. Normally the brakes are very consistent, they slow and stop the car quickly and safely, however when the brakes are applied while riding on rough roads they become very inconsistent and…

The vehicle was parked in a typical supermarket parking lot during a normal sunny day. The vehicle starts normally as the brakes are depressed. After putting the car in reverse, the brake pedal pushed back as the vehicle starts to back up. The brake felt very stiff and would not depress until the foot is lifted and re-stepped on it. It has happened about a dozen times in the last 3.5 years, no specific place or…

When braking while the vehicle is going over a bump or depression in the ground, the vehicle lurches forward. Instead of stopping the vehicle seems to accelerate forward. This happens consistently in this setting.

I was applying my brakes as i was going down a slight incline over a bridge that is under construction so the road is bumpy. The car acted like the gas was applied instead of the brakes. It lurched forward a little before the brakes fully engaged. *tr

My car hesitates to stop or slow down when brakes are applied driving over a pothole, slick surface, metal road cover or a manhole. Instead of slowing/stopping, the car seems to eject forward. I took it to the dealership where i bought my car and drove with a service tech and he said in over 20 years of his experience, he's never seen this. I tried to explain that this car (and technology with regenerative braking)…

While deploying brakes if you go over bumps they fail to brake properly. Feels like a speed up. This has happened numerous time while braking for traffic light or making turns.

The brakes total disengage when applied on bumpy roads then work again after getting to a smooth surface. I reported this to the service manager at the new car owner meeting at toyota and was told that i just have to get use to antilock brakes. I haven't gotten into an accident yet but i had several close calls almost hitting cars in front of me on bumpy roads. Has there been a recall for this problem? *tr

This has happened multiple times since i purchased this vehicle. The first time this happened was at 2,500 miles. While applying brakes on a rough road or when crossing a pot hole, cracked road, or bridge joint the brakes fail momentarily allowing the car to lurch forward. It his happens regardless of the speed. I could be traveling at 15 or 50 mph and the brakes will fail and lurch forward. I purchased the prius…

On april 3 2012 we drove our 2011 toyota prius to a full and complete stop at a stop sign in a residential neighborhood. While we were stopped, the car surged forward approximately 5 feet before coming to a stop. My wife, who as driving looked down to check that her foot was on the brake. While staring at her foot squarely on the brake, the car surged forward again about 3 feet. The car then surged forward again…

In january 2012, i purchased a new 2011 prius iii because i commute roughly 90 miles per day between home and school. Thinking this was the optimal vehicle i didn't think twice when signing on the line. This was my first new vehicle, and to be honest i had heard nothing but great things about toyota & thought i was going crazy when i started having issues with my brakes. Prior to owning this vehicle i own a subaru…

Just want to add to the list of complaints about this car lunging forward when the brakes are applied, primarily when the car is driving over rough terrain but not always. It is always unexpected. I've had to change the way i drive, but i'm not always sure i could stop it in every circumstance. I've taken the car in to a toyota service center twice to look at it. They either can't get it to happen while they have…

Periodically, after going over a bump at fairly low speeds, the car will accelerate. In light of the other unintended acceleration issue reported under odi 10499911, i wonder if these two events are related -- possibly something to do with going from the motor to the battery? *tr

While applying brakes on a rough road or when crossing a pot hole, cracked road, or bridge joint the brakes fail momentarily allowing the car to lurch forward. I purchased the prius new in 2011 and have told the service folks at toyota about the problem and they always tell me it?s normal for a prius without noting anything in my file. I am here to tell you that the prius brake design is faulty and the nhtsa should…

Vehicle loses braking function while traveling over potholes, recessed manhole covers, and all other types of rough road surfaces. Braking function is delayed and does not return to previous power/braking strength after traversing the obstacle; this results in the need to depress the brake pedal further to re-engage enough braking function to stop the vehicle safely. Serious concern is that if the vehicle is under…

When i push on the brakes and i happen to go over a bump or a pot hole, my prius speeds up. It accelerates when i try to decelerate. I have to push harder on the brakes to really slow the car down. This problem happens when i'm driving at around 40mile/hr. I have a 2011 type iii prius. I took my car to the toyota dealer and they claimed that they could not reproduce the problem. This is total bs because as soon as i…

Noticed brakes breaking intermittently about a week after purchase. Dismissed it because of weather and it was a new car, thought it was just different feel from my last vehicle. I don't drive often averaging 10,000 miles or less per year, so when i noticed this problem repeating, and actually near causing an accident i got concerned. Took it to the dealership today, they found nothing wrong, and on the way home…

Tl* the contact owns a 2011 toyota prius. When the vehicle was placed into reverse (when the electric powered fuel motor had not been running), the brakes began to seize when the brake pedal was depressed. There were no warning indicators illuminated. Also, during cold weather, the engine and entire vehicle shook. The contact called precision toyota of tucson (700 w wetmore rd, tucson, az 85705, [redacted]) and…

From the very start of my owner ship of a new toyota prius, the car started lunging when i would try to stop. It has continued to do so and i finally asked a friend who also has a prius if she has that problem too and she does. I don't know what to do but i fear the safety of a car that lunges when you are trying to brake. Thank you for your time. Updated 11/24/2014 *js

When i brake at the end of my road which has small holes or bumps, the car shoots forward very fast before it stops. This has happened numerous time. I thought at first i imagined it, or my foot slipped, but since it has happened numerous times i knew something wasn't right. So i got on web and started goggle it. And sure enough its happened to other drivers. *tr

First incident: was traveling approx. 68 mph on 405 freeway in los angeles (downhill into the san fernando valley). Dry conditions. Attempted to stop as cars ahead of me began to slow/halt and car lurched forward, carrying me to almost hit the car ahead of me, stopping only inches behind. Dealership could not replicate and dismissed my concerns. Multiple similar incidents all in good weather have occurred. Most…
