Approaching state hwy. In cruise, assumed stop area would be slippery as it sometimes is in the winter..tapped brakes to disable cruise, applied brakes, kept right on going & ended in the ditch across the hwy. Was lucky that there was no collision.. can't remember if the motor was racing at the time.

My 2006 Prius has on at least 3 occasions has accelerated inexplicably on at least three separate occasions. The first two incidents occurred during my first year of ownership and were reported to the dealer. I was told there was no problem. The most recent event was in December 2009. I was driving down the highway when the car began accelerating rapidly, even after I removed my foot from the gas pedal.. I was able to slow the car down and pull over safely. Please note that at this time, I had already removed the floor mat as suggested by Toyota. Again, I was told by the dealer that nothing was wrong with my car, a response that did nothing to reassure me. I was told in a follow up call to the dealer that Toyota would be doing nothing to assist with this problem.

I received notification from Toyota some months ago of a floormat/accelerator problem indicating they would contact me when a solution was available. It has now been months with no word. Recently, I contacted them only to get a response concerning a 2010 Prius braking problem. My vehicle is a 2006 Prius.

I have experienced extreme acceleration when using my cruise control on my 2006 Prius. I have not determined how fast it would continue to go for safety reasons so when it has started to accelerate extremely fast, I would turn off the cruise control so as not to continue to accelerate that fast. I would turn it off as soon as I began to feel out of control with the car.

1. driving on the highway with the cruise control on. 2. we could not get the cruise control to disengage. Neither tapping the brake or the cruise control switch would turn the cruise control off. We had to slam the brakes to disengage. 3. we turned the car off and restarted it. That fixed the problem, but we have not used the cruise control since. The Toyota dealer could not find anything wrong.

I have a 2006 Prius. When I drive over a wet/icy spot or a road grate (like a metal drain) my car seems to skid and the rough road light comes on. This does not happen while I am braking, but while I am accelerating or driving normally. I have purchased better tires, which helps a little, but I still experience this issue. I have always assumed it was a design flaw and I try not to drive my car in any bad weather. Toyota has issued many recalls for similar issues, but my car doesn't seem to be covered.

Unintended acceleration in my 2006 Toyota Prius. Lasted less than 30 seconds. Responded to repeated braking and hitting and pulling with my foot on the gas pedal. It happened when I floored the gas pedal to pass another vehicle.the pedal was not stuck to the floor mat. I could not reproduce the event after it occurred by flooring the gas pedal again.

The brake problems with the Toyota Prius go beyond jus the 2010 model. I have a 2006 Prius and it does the same thing re: The brakes seeming to "slip" when you hit a bump or a slick surface. Also, when you tap the brakes, and then hit the accelerator (as when avoiding another car that is doing something stupid) it sort-of "stalls" for a few seconds before it will accelerate.

- Denver, CO, USA

I currently drive a 2006 Toyota Prius and have had numerous instances of brake slippage when going over a bump/pothole during deceleration or acceleration. Upon further research at priuschat.com, an online community of Prius owners, community members advised that this was "by design" since the vehicle's computer thought that loss of traction when going over an obstacle was considered as a stability issue hence dis-engaging the brakes (ABS). I have had several fender benders without the air-bag deploying though.

Starting up my Toyota Prius coming out of a car wash the engine stuck with high revs. I confirmed it was not the car mat because I had been in the car wash and that was my thought. Could not get the engine to stop over revving (was consistently high). Never went into high speed. Was able to control it by putting it in low gear and neutral at the intersections. In less than 1 mile I turned off the car and did not have any follow-on problems. Not the car mats.
