I've experienced 2 problems with the brakes on my 2010 Toyota Prius. The first happens when I am applying my brakes while going over a pot hole. The brakes appear to release and catch again. This has happened numerous times under the same conditions. Secondly, I've noticed that when the car has been parked and the wheels get wet, whether by rain or from washing the car, as I backup or go forward down an incline, the brakes seem to "grab" or "stick" when light pressure is applied to the brakes. The resulting stop in the car is as though I had jammed on the brakes quickly and with a great deal of force.

This is regarding the 2010 Toyota Prius. I just traded in my 2008 Prius for the 2010 in December 2009. I have experienced temporary loss of brakes 3-4 times when hitting small pot holes. This only lasts for a couple of seconds, but it appears to happen randomly with no warning. I have contacted the dealership where I purchased the Prius, but they cannot act until they hear from Toyota. So, I must just drive as safely as possible, and stay alert.

Toyota 2010 Prius braking problem -- I purchased the car 8/09 and within about 1 month noticed brief braking failure -- at first thought it was my imagination. Later thought it was from losing grip with the road surface momentarily as in going over a surface irregularity. This happened several times albeit intermittently. Then for a couple of months it was not a noticed problem. Last weekend I experienced it again. It was on a clear and seemingly even surface as I tried to slow coming to a traffic light. It is brief and then the brakes do successfully engage.

I was approaching an intersection in December during a snow storm. The road was snowy and I braked, but my 2010 Prius did not immediately stop. I went 10 - 15 feet before the car stopped. It was very scary, but luckily there was no other car in the road, or I would have been hit.

2010 Toyota Prius braking issue...I have had this issue a number of times. I will be driving and see a pothole/bump coming up. I slow down and brake but once the car goes over the pothole/bump the brakes do not work- instead the car accelerates forward with a lunging/jerky feeling. It is not right. I took the car into the dealer on 10.27.09. They could not "duplicate" this problem and could not fix it. I called Toyota headquarters and they opened a case. They said I should take it back to the dealer and to see if they could duplicate it. Case # 091139820. There is a big problem with the brakes- the car should slow down/stop and not speed up. If a car or pedestrian had been right in front of my car I would have hit them no doubt.

Multiple times when braking in my 2010 Toyota Prius, the car has suddenly lurched forward instead of stopping. In all these incidents, the road was either slightly wet or the car had just moved over a bump or pothole.

I purchased a 2010 Toyota Prius in mid-June. I am writing to report that I have also experienced the loss of brakes while traveling over uneven surfaces three separate times. It is quite unnerving when you are in mid-brake and it momentarily stops working. I am a very safe driver, keeping a good distance between my vehicle and the cars ahead of me; however, sometimes you do need to stop suddenly and I am concerned that if there is a pot hole between me and the car, the Prius will not be able to stop in time. This problem has not resulted in any crashes but I hope that Toyota takes these complaints seriously and does everything possible to fix the 2010 vehicles manufactured before January 2010. On that note, I was extremely surprised to hear that Toyota knew of this issue and fixed it mid-year but did nothing to notify the owners of the initial 2010 model of their findings or offer a fix. That is bad business practice, something I did not expect from Toyota.

My Toyota pruis 2010 which I purchased on Nov.30 2009 had unexpectedly lurched forward when I was slowing down and applying the brake. I was taken by surprise and fortunately it stopped after I stepped on the brake very hard. This has happened several times already.

Whenever I am driving and hit a pothole or bump on the road, immediately after going over the pothole or bump I feel like my Prius surges forward or speeds up. This happens whenever I am going at a constant speed or when I'm braking. It has happened since I bought the car (two months ago) but yesterday morning it scared me more because I was going over a really bad road with many bumps. As I approached a red light I began to brake early but as soon as I got close to the stop there was a bump before it and my car lunged forward causing me to stop past the white line of the stop sign. This happens all the time when I hit a pothole or bump on the road.

2010 Prius - brakes stop working if they are being applied when car goes over bump or uneven road service.

- Scarsdale, NY, USA

I own a 2010 Toyota Prius which was purchased in September 2009. My brakes fail to immediately stop my car when applied going over bumpy sections in the road, hitting a pothole, or when on slippery sections of the road. When hitting a bump it actually feels like the car lurches forward. The car will eventually stop after pushing the brake to the floor with force. It is very disconcerting and the potential for hitting the car in front of you or a person is very high.

Drove car over several potholes and attempted to bake quickly. Brakes failed and I hit car in front of me. My car bounced off car in front of me and I again hit brakes sharply. They failed again and I hit the car in front of me again. Road conditions were wet and slippery.

On occasion the braking on our 2010 Prius has not felt right. Sometimes when braking and hitting a bump or pothole, there seems to be a brief period where the car feels like its accelerating or the brakes are not slowing it down properly. Keeping pressure on the brakes gets by the problem but it is very unsettling and I have never had this problem with brakes in any car before. It has happened a few times since we bought the car in July 2009 but very intermittently. The date I am picking is just an approximate date for one of the incidents. I am reporting this now in light of the recent publicity about similar events reported by other owners, which made me realize what I had been noticing was a real issue.
