The problem with my 2007 toyota yaris is sudden acceleration with accelerator getting stuck at partially depressed levels (around 50-60 MPH). I have to press brake several times to get it to stop. This is sporadic and happens without warning. I took it to vann york toyota in high point, nc and they told me the cause of my problem was after market floor mats. They concluded this after one time traveling around 60 MPH. This is not the case because this happens without the floor mat interference. This is still happening and I am afraid that it will get stuck and I won't be able to stop it. I have learned that toyota recalled vehicles for this exact problem but I never received a recall notice. Please advise me on what I should do. Thank you.

I was driving my yaris and attempted to pass another vehicle on a 4-lane road. I pressed on the accelerator pedal as I entered the left lane and nothing happened. The pedal went halfway down, but the engine did not respond. As I quickly tried to decide what to do as a car in the left lane behind me came up fast, the engine responded unexpectedly and I surged forward. The next time I depressed the pedal, it responded normally at the top of its travel. However, it happened again about 3 weeks later when I was stopped at a red light. The light changed and I pressed on the accelerator. Again, no response. This happened on and off until last week when it started to become more common than the normal response. Since I didn't want to pay toyota for an expensive fix only a few thousand miles after my warranty ran out, I resolved to get used to it. I adjusted my actions so I didn't expect an immediate response from the car until the pedal got part way down to the floor and, though I'm sure it affected my gas mileage, I could deal with it. Then yesterday, as I pulled into my garage, the pedal response suddenly went back to normal and I almost went through the back of the garage. I bought this car (and one for my wife as well) because of toyota's reputation for reliability and its fuel economy. Now I don't know what to expect. I have read that lexus owners have reported the same problem. This is annoying, reduces gas mileage, and could be very dangerous.
