2010 Toyota Prius was placed in "parking" in my home garage, as I turned off the "heating" switch to the seat, the car rolled forward on its own and hit a work bench chair in front of the vehicle. No personal injury was sustained, but the car had some dents to the front end.

My 2010 Toyota Prius would not start after a brief 45 minute lunch with friends. When I released the parking brake and let off the brake pedal I didn't know the car was stuck in neutral. This error was on the dashboard "malfunction when parking, park in a flat place and apply parking brake securely". when I let off the brake the car rolled back into the middle of the parking lot. I had two coworkers in the car with me; they got out and pushed the car out of the way to a flat location. Car still was disabled. I called Toyota roadside assistance and waited an hour for a tow truck; after about 45-50 minutes of waiting I was hit by a woman that wasn't paying attention; she backed into the side of my disabled car. I was pressing on the horn and she didn't hear. The impact must have freed some stuck component or something because 2 hours later when the tow truck finally came, the car worked again; no warning lights etc. Toyota looked at the car and says there is nothing wrong. I took a photo to document the warning message (plus have 2 witnesses).

2010 Prius II - when in park, or just slightly on the brakes and the engine switches from electronic to gas motor, the car rocks forward 1-3 inches. Very terrifying, but according to kendall Toyota of eugene, Oregon, this is "normal". I don' T know of any world in which a car moving on its own while in park is normal.

True! gear problem! remember airbus flipping our of control when they came out with fly by wire? the joy stick gear is default to shift into neutral when normal push bring it in to reverse. No way to put it in neutral. I thought the same thing & was in denial until I realize that its impossible to put it into neutral when thing is speeding out of control. Don't take it lightly- I did bought a 2010 Prius just now & realize - U can't put it - in neutral. I was in denial. Also, ventilator fan suddenly accelerates when U try to switch the modes.

Not just the brakes, it's also the park button on the 2010 Toyota Prius. Besides the cars brakes not working and being the cause of a recent collision, there is another safety issue. The car has a park button and that I accidentally pushed when I was driving, thinking I was reaching for the heater button. The car completely shut off. I was on the freeway and the car engine was cut off. When I stepped on the gas, the car would not go. I was almost hit in the rear end by a semi truck until I could get the car pulled over and stopped. Toyota should have a safety feature on this car so that the parking button will not operate while the car is being driven.

I bought a 2010 Toyota Prius II November 2009. Within 1 month period, I had experience two separate brake problem. Once was passing a railway track and the other time was making a right turn. Both times I stepped the brake to reduce speed and failed. That means the brake did not reduce the speed of the vehicle. Fortunately, no car was in front me and no accident happened. I then reported to my dealer and sent my car back to check. The dealer told me they failed to replicate the situation and everything was normal. Nothing was done. They then talked to Toyota customer service line and Toyota said it is normal to feel the brake did not engage when crossing a bump. I was really disappointed.
