problem #422

Jan 162010


  • 5,000 miles


I was driving my 2010 Toyota Prius on a snow covered, rough residential street. While turning into a driveway to turn around to grab a parking spot, I applied the brakes and they completely released and I slammed to the snow piled at the entrance to the driveway. The front bumper cover got a hole punched into it the size of a baseball from the frozen snow. Since then the brakes have released without incident but not without concern. I called and reported the problem to my Toyota dealer and he asked "do I have an error showing up on the dash screen" and I said "no". I asked was there a new updated program and he said he did not know anything about it and they don't have a fix anyway. This was before the car was recalled by a couple of weeks but after Toyota had started loading a different program onto the car. On Feb. 17, 2010 Toyota did flash the car's computer to fix the program issues. I would like Toyota to have the front bumper cover repaired. Thanks.

Intermittently, while I am braking when approaching an intersection the car will momentarily accelerate quickly. With pressure on the brake the car then slows. This has happened about 6 -10 times since I bought the car in Sept. 2009.

I own a 2010 Toyota Prius. I have experienced some dangerous occurrences while driving. 1) occasional loss of traction (for a second+-). problem has occurred Aug, 2009 - present. Usually occurs when heading downhill or when driving over a manhole or drainage cover. Car feels as if slipping or airborne for a moment.. 2) frequently immediately after starting car, at slow speeds of only 0-5 mph, car is jerky each time brake is applied. Problem has occurred Aug, 2009 - present. Passengers are actually jerked, as if driver was applying brakes too suddenly. Even with great attempt to stop smoothly and gradually, it is impossible. Brakes grab and jerk. This occurs both in reverse and forward, yet not every time engine is started. It lasts for only a minute or so, but makes maneuvering while parking or entering traffic unsafe, as well as making driver look inept. I cannot figure out if this is a braking or acceleration problem. When calling a Toyota dealer (Nov, 2009), I was told they had no similar reports of these problems and offered no solution. My concern has increased with the recent recalls when calling a Toyota dealer previously, I was told they had no similar reports of these problems. My concern has increased with the recent recalls.

I purchased a 2010 Toyota Prius in September of 2009. Three times I have experienced issues with sudden acceleration after braking on a rough surface. Two were in the same area where I was slowing to turn into a business and while braking I hit several small pot holes in the road. As soon as I hit the potholes I had a sudden brief acceleration where my brakes did not seem to work. In a short time the brakes seem to take hold. Since there has been the recall and issues with accelerating with the cruise control my car has been parked. I have an appointment to have the vehicle looked at on Thursday, but I have not received a recall notice.

I have a 2010 Toyota Prius. I noticed that when heading downhill on a road with many bumps, payment irregularities, etc. That the braking would total fail for about 1/2 a second. I was always careful on this type of road to reduce speed earlier to compensate. I had the recall reprogramming performed on 2/12/2010.

Brake failure on 2010 Toyota Prius. When going over a traffic bump on a rainy day, the brake failed for about 1-2 seconds before I was able to bring it to a stop at the traffic. There was no accident, no property damage.

While driving a 2010 Toyota Prius it sounded like the rotors were squealing so loud we had to pull over and check the rotors and brakes. However, nothing looked unusual so we slowly drove back home. Me and my wife then proceeded to return home slowly and the sound continued all the way home (10 miles). Since then we have parked the vehicle to await results of recall that, which has been announced today.

Since I bought my Prius back in July 2009, my brakes have been great except for the 5 or 6 times when the brakes disappeared for a second as I pulled up to a stop sign on a bumpy road. It's happened twice at one stop sign where I drive just once a week. That one has a big dip in the road where they have replaced a water line and then repaved. My occurrences have all been within 20 feet of the stop sign and never near a car or pedestrian fortunately. I now have 14,000 miles on the car. With something this rare, the dealership was of course unable to reproduce the problem. The next day Toyota announced that it had fixed the problem in late January on the line but had no fix to offer us yet. Brakes are great otherwise; the best I've had. Recently I have had plenty of opportunity to test ABS, traction control and stability control. No problems except for those half-dozen incidents.

While applying moderate pressure to the brakes on my 2010 Prius and while driving over a bumpy road, the brakes seem to momentarily, but completely fail. Then the car seems to briefly accelerate (or at least free-wheel) before the brakes feel like they're starting engage and work again. This has happened with this new car since the day I purchased it in July of 2009. It does it every single day, as I drive over the speed bump while driving out of the parking garage near my work.

Problem is with my 2010 Toyota Prius, brakes seem to fail and the vehicle will actually lurch forward when braking on a bumpy or icy or snowy conditions. Date given below is approx to when I bought the vehicle and is a constant problem and ongoing. It is difficult to reproduce though, and you never know when it is going to happen.

problem #403

  • 18,800 miles
I have had problems with my brakes working in my 2010 Toyota Prius. I was driving on a cold, wet road that was bending to the right. I pressed the brake pedal to slow the car, the car stuttered then accelerated while I was braking. The car slid off the road, into a ditch, and accelerated itself out of the ditch on the side of the road, the whole time I was depressing the brake pedal. No one was injured, no property damage was sustained, and there were no other witnesses. The left front bumper of my car sustained body damage that has not been replaced or fixed. The left front wheel well was pushed out of place so that when I turned the steering wheel at a sharp right, the left front tire would rub against the hard plastic wheel well. I had to pay to get the wheel well pushed and bolted back into place. This is the incident that took place on January 28th. Prior to this incident, I have also had other times when the brakes failed, most often when I was driving at night when it was colder outside. They had failed at least three times while I was depressing the brakes to stop at a stop sign. While I depressed the brakes the car would jump forward and accelerate instead of slowing. I would have to take my foot of the brake and reapply pressure to get the car to come to a stop.
