1. after turning off cruise control, vehicle accelerated on its own up to 95M.P.H. until I was finally able to get it stopped by pressing the brakes to the floor. After getting the vehicle pulled over to the side of the interstate, there was a lot of smoke coming from the front brake pads. I restarted the vehicle in an attempt to get it off the interstate for further inspection. As I exited the highway, I turned the vehicle onto the off ramp but the vehicle did not turn and drove us directly into the guard rail. I contacted Toyota and they have denied there was anything wrong with the vehicle and dismissed my complaint.

Multiple issues with 2009 Prius. First: Loss of air pressure in front left tire from time I picked up the vehicle to present. I continually need to put air in the tire, usually on a weekly/bi-weekly basis. The other tires are fine. Second: For the same tire, the tire pressure light would not be triggered until ~23 pounds, should have been triggered in same tire at 33 lbs. Third: Vehicle would not stop when applying pressure on brakes at slow speed. This has occurred about 6 times in a 6 month period. Simultaneously, the vsc light went on and the slid indicator went on. The terrain was on either asphalt or concrete roads, slightly downhill (concrete) and one street is a bit rough (filled in pot holes). Also, both areas are within a quarter mile of each other and near the ocean. With each occurrence the vsc went into effect. On 11/21/09 it jolted hard much more than the other occasions; this date was the incident on the bridge when the car was going in a slight downward direction. I lost control of the vehicle for several seconds and was afraid that I would hit the car in front of me; I beeped my horn to warn the driver in front of me. My vehicle did stop in time but it took alot longer than it should have taken. On a later occasion, I was going about 5-10 mph faster on a nearby street and attempted to stop for a stop sign and it did the same thing, however the vsc did not jolt back as hard. The vehicle was not angled down as much as the 11/21/09 incident. On 11/21/09 I took the vehicle to cabe Toyota dealership and they looked at the car but found nothing wrong with it. I also had the car looked at by Toyota Corp today and was told that the driver feels that I felt the ABS brakes only. This is not the case. When I stepped on the brakes each occasion it was as though there was nothing there and I had no control in stopping it. This was especially true when the vsc kicked in (the jerking). Each time it lasted many, several or more seconds.

In addition to the traction control, ABS, gas pedal/floor mat problems with the Toyota Prius there is also a safety issue with the power button. In an emergency situation, like the door coming open, throttle getting stuck, etc. You can't power off the vehicle quickly. You must hold the power button for some amount of time before the car will shut off. Unlike the Toyota Camry example where they suggested turning off the ignition, you can't do that on the Prius. You also can't remove the key/fob to turn the vehicle off or power it off. There is also an extreme under steer problem with the vehicle which is a safety concern. In wet conditions it is exacerbated. It can be observed on clover leaf overpasses and general cornering.

I keep hearing about the momentary loss of braking on the 2010 Toyota Prius. However, I have encountered the same problem on my 2009 Prius. When passing over a slick, bumpy, or icy surface, I experience a momentary loss of braking, and a warning light that looks like a car skidding comes on for less than a second. This generally occurs at slow speeds, but has occurred at speeds up to 25-30 mph.

I have a 2009 Prius and on at least 4 occasions in cruise control my car has accelerated without my doing so. All of the times I was able to brake and bring down my speed. We tried to report this to Toyota but they were not concerned. We then reported this to the dealership and the mechanic told my husband that " that sometimes happens". no report was filed or action taken.

I was driving a 2009 Toyota Prius and came to a stop at a friend's garage. All of a sudden the car accelerated forward, it hit an old fir tree and a brick wall. I checked and the floor mat was in the same position it always was. A friend pushed the fender back into place and the Toyota dealer buffed out the scratches. I have contacted the dealer several times about checking out the accelerator. But they always tell me that I have to wait for a letter. I am very nervous about driving this vehicle and am having nightmares about this incident.

2009 Toyota Prius issue: Dealership: There has been no response/recommendation despite multiple voicemails and email dated 2/6/10 to Toyota-service@daytontoyota.com. Toyota: Awaiting response from Toyota case manager after two phone calls, once on 2/9/10 and one on 2/10/10. Summary: 1. I want to bring to your notice that I experienced a sticking accelerator problem several weeks back, while pulling out of the driveway, when the car was moving in reverse and would not stop despite the brake being pumped a few times. The car was finally brought to a stop by pressing the power button for an extended period. I do not have any additional floor mats in the car, besides whatever was available with the basic package. 2. when braking on puddles/pot-holes the car seems to stall and the orange light turns on.

The unintended speeding also happens on 2009 Toyota Prius when driving on a bumpy road, this happens every time when I hit a pot hole on one tire, car pulls to the opposite side at an increased speed and brake seems too slow to react.

I noticed on my Toyota Prius 2009 takes about a second or two to actually brake. I noticed that even when I start braking slightly the car does slow down but I have to press harder (more than half way in) for the car to respond on braking.

I purchased a 2009 Toyota Prius in April 2009. On at least four separate occasions I have had issues of my vehicle surging forward or being hard to stop after driving over a potholeand when driving on a washboard roads (1 time on the pot hole the other times were while on the dirt road). I just figured the vehicle didn't handle well dirt roads and pot holes so I am just extra careful in those conditions which is why I did not think to report this until now when I heard the report on brake issues with the Prius. I do not know if my problem is significant of not, I thought I would report it just in case. I do not have approximate dates, just between April and September 2009.

I recently read the following article money.cnn.com/2010/02/03/autos/prius_complaints/index.htm and would like to report that this problem occurs in my 2009 Prius. I have had it since 4/09 and it occurs consistently when I am exiting my workplace. I descend a fairly steep paved road and when I hit a specific bump in the pavement, my car accelerates for a split second. This is a regularly repeatable occurrence.

- Durango, CO, USA

While crossing a small bridge over an expressway, applying brakes at the point of bumpy transition caused the vehicle to lurch forward for approximately one second. This caused a sudden panic, but no other effects. This is the second occurrence at the exact same bridge transition and bump over the course of 8 months. There are no recognizable side effects. This has not been reported to the dealer, nor to the company.

November of 2008 I bought a 2009 Toyota Prius. Since then I have experienced 4 incidents where the accelerator became partially depressed causing an unprovoked acceleration, the most recent being on Sunday, January 24, 2010. I contacted the Toyota dealership where I bought my car the very next day (1/25/10) and reported all 4 incidents. I was told by the Toyota representative that there was nothing that they could do. I was given an 800 number to call to report my concerns. I received an automated reply telling me to call back at another time. I have been calling back but to no avail. I live in the high desert where it sometimes snows and the highway can get icy during the winter. I fear for my safety and the safety of other motorists if I continue to drive my Prius due to the unpredictability of the accelerator sticking. I am retired and live on a modest income and cannot afford to pay for the repair of the accelerator problem. In the incidents that I have described the sticking of the accelerator was not caused by the floor mat or any other accessories.

- Morongo Valley, CA, USA

2009 Prius purchased May 15, 2009 has 4,675 miles on it. Acceleration/surging forward or not properly accelerating at other times. I do not have the floor mats mentioned in the recent recall. I am concerned about other possible issues with sudden engine acceleration and problems controlling vehicle. Have taken car to dealer several times and they told me it is "bad gas" or my driving habits. Called Toyota and they told me to take car to dealer for them to try and repair it. Dealer still claims they cannot "replicate the problem" therefore there is no problem. Car mileage now down to less than 17 mpg. Lacks heat or heat does not properly function. Have had 5 instances of surge /acceleration "incidents. Some when going up hill and had trouble gaining power then when I put foot on brake it suddenly lurched forward rapidly;maybe to 60 or more mile per hour at an exit ramp. Had to keep braking in order to stop. Other times only leaving driveway..went from reverse to drive and car hesitated then "surged" forward rapidly before I was able to brake approximately 20 ft ahead. This had happened three times like this & twice when going up hills where I lost power and then the car suddenly surged forward and I had trouble stopping it. Very frightening, especially when dealer tells me nothing is wrong with my car and won't do anything about it..even when I have contacted them numerous times and have driven there to speak with them about this. Something is wrong with this car. Now the mileage has dropped right off to 17 mpgs. What is going ?
