    Pedal will be all the way down to the floor and still only going 20mph and creeping. Every now and then the transmission doesn't know what gear to be in so sometimes it doesn't go to first of 4th gear.

    I've been having the same problem with the accelerator pedal. I was driving on the parkway, going about 60 MPH, and suddenly the ESC OFF light came on and I couldn't get the car to go above 20 MPH. Very dangerous when driving on a crowded highway. I pulled off to the side and restarted the car. It happened several more times on my drive to work. Taking it to the dealer today.

    CEL and ESC light on codes were throttle position sensor. Dealer replaced sensor cost $148.00 total.

    While driving the engine malfunction and ESC lights came on and the car lost all power. I coasted to the side of the road and turned the car off, then on. The ESC light went off, but the malfunction light stayed on and continues to stay. The car seems to drive OK.

    I was stopped at a stop light and when I tried to accelerate as the light turned green, it felt like the engine lost power and made a little bit of a whirring noise with no acceleration. As this happened, the engine light came on. I turned the car on 3 times after the incident and the acceleration seemed to work fine each time (I was able to drive on the highway and everything, maybe by the grace of God)... but the check engine light never turned off. I went to my mechanic today to get a diagnosis. Apparently, it was the accelerator sensor. We called the dealer and they said I have to replace the entire pedal. Bummer.
