After the recall, was completed on my car, I continue to feel brake failure. I call it brake failure when I am pushing on my brake pedal and braking in not occurring. This seem to be a common occurrence on rural roads. I live out in a rural area and feel like my car does not handle well at all on these road. Seems like the braking systems works great in town and on the main highways. I am very unimpressed with this Toyota. Again for all of you out there that seem to think this is nonsense, make me an offer on my car. I am looking to sell it!

The ZVW30 model had the advantage of a brake fix already being applied on the assembly line. The problem it fixes are a momentary pause in the braking:
You'll notice there was brief pause in the braking approaching the gate entering Redstone Arsenal. In more detail:
Unfortunately, I have not heard of a similar fix for the NHW20 models, 2004-09. But there may be some relief coming ... not soon but eventually.
The new CEO of Toyota has formed a quality committee that he chairs with representatives from every continent. It doesn't mean things will change instantly, he is having to rebuild the quality institutions that seemed to have waned in the past. But the direction is clear. Steve St. Angelo it the North American officer. I would recommend sending him a letter and giving him and Toyota a chance to 'do the right thing.'

I had a similar problem. Turned out to be a faulty skid control computer-$2200 and scared the shit out of me! I also am looking to dump mine. Loved it to this point, but just feel unsafe now. Anyone else had this experience?

Please describe the incident. Many are probably curious. Thanks.

I have had the automatic acceleration problem 3 times. Two times when I was driving it and 1 time when my husband was driving it. We do have documentation on this from toyota. The brakes would not work in normal driving conditions and the accelerator would not stop accelerating. this was not a floor mat problem. I tried to pull the accelerator up but it made no difference. The documentation was about a year before anyone mentioned it in the media. Toyota did not want to document this for me but my husband went back and insisted. Some of their salespeople are telling people that this is basically a hoax. Beware.
I have always had success with our other toyotas but would not even want to sell this prius to anyone for fear of them being in a serious accident. I do not want someone else's death on my conscience.

Yours would be a first -- a combo of "automatic accel." and nonworking brakes. I can't figure the probabilities, but they have to be on the way to infinite, as I think those two systems are not linked. What year Prius? Could you please tell us more detail on both the acceleration and braking incidents. I don't mean to pry, but it is always helpful to see if there are any parallel's w others' experience. Also, the self-serving dealer aside, have you reported this to Toyota Motor Sales USA, Toyota corporate (Japan), NHTSA? I think at all three of those, you would get maximum attention and they would want to inspect your car. I appreciate your concern about selling it to anyone.

That resistance to documentation is what many people seem to have experienced through the years. That's not a good trait in a car company.

I believe the two are related. The computer controls the regenerative braking just as it controls the acceleration or doesn't control the acceleration in this case. The computer controls the switch from regeneration braking to applying the hydraulics brakes. That switching process with its noticeable, and dangerously long in some cases, lag is what a few people have complained about and has been reconfigured on the newest of the Priuses.
However, the computer gone crazy and giving full acceleration probably isn't goiing to be a computer also correctly apply regenerative braking nor will it apply the hydraulic system correctly.
