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.

2010 Toyota Prius I've had at least 2 experiences where under hard braking and transitioning to different levels in road surface, the vehicle has lurched forward. When this occurred, each time, I thought I had been hit in the rear causing my vehicle to be pushed forward. I blogged other owners, and have been trying to get an answer for a few months. I saw the recent news on Prius brakes and feel this is what's happening with my 2010 Prius.
