I drive a 2010 Toyota Prius. On multiple occasions while attempting to slow down on rough surfaces, the brakes temporarily stopped working for 1-2 seconds even though the brake pedal was depressed. The most recent incident occurred while exiting the highway and attempting to slow down quickly on rough pavement. Luckily, there were no other cars in front of me or there would have been a collision. If a car had been in front of me on any of the occasions then there would have likely been a collision.

The brakes on my 2010 Toyota Prius failed to engage while driving over a pothole. The car seemed to accelerate briefly but then the brakes kicked in once I hit the brake pedal again harder. This is the third incident of similar problems since I purchased the vehicle in July 2009.

1. I was driving on a local road and was switching lanes. I pressed my brake pedal very slightly as I was crossing the lane divider and as I hit one of the plastic bumps, my car accelerated forward. 2. this has recurred many times and there were no vehicles in front of me everytime it happened so I was able to come to a stop. Several times I would either cross the pedestrian walkway at the intersection when this acceleration occurs. 3. I took my car to the dealer several times and everytime they told me it was normal and there was no problem. They were lying and completely clueless!!!

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.

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.

We drive a 2010 Prius, purchased this fall. On three separate occasions, when I tried to brake in an area with some ice, the car accelerated rather than stopped. On two of the occasions, I failed to stop at an intersection (no one coming in the opposite direction) and on the third, the ice patch was about 3 ft in diameter on one side of the car only. I was going rather slowly, following a car that slowed for a speed bump. Luckily the other car accelerated and I did not hit it. The speed bump slowed me down and then the brakes started working.

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.

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.

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.

Applied brakes at a stop light. The Prius (purchased in July of 2009) ran over a bump, and it seemed like the brake disengaged. I removed my foot from the brake pedal and reapplied the brakes. The brakes seemed to engage and came to a stop.

2010 Toyota Prius braking problem. I bought a 2010 Toyota Prius approx 4 months ago. During the approx 10000 miles I have put on the car, I have experienced a braking issue approx 5 to 6 times. Most times I was braking for a stop sign in a 30 mph zone. Once I was braking for a red light in a 45 mph zone. Each time, there was bumpy road during the braking, and the brakes released. I can't say if the car accelerated, or it just seemed that way because of the brake release. It did not cause any accidents, but once it was on a snow covered hill and I slid out into a 2 lane 50 mph highway. There was no traffic, and therefore no accident. Another time, I was stopping from 45 mph at a red light, and under braking, again on bumpy roads, the brakes released and I nearly hit the car in front of me. The brakes released enough allow me to panic and jam the brake pedal to the floor. The car stopped quickly.

My 2010 toyata Prius (purchased in Sept. 2009) has had repeated problems while braking over a patch of road with small potholes. If the brakes are engaged while over the patch of uneven road, the car lurches or "jumps" over the spot on the road and the brakes don't begin to catch until the car gets over the patch. This has happened 5-10 time over the last four months at a stop light.
