    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.

    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.

    the car wants to quit every time that we made a stop, and we run a diagnostic and the computer said that was the coil #1 that is wasn't working and also the cap of the gas wasn't good, so we change the coil for a new one, but keeps doing the same thing, also we change the spark plugs, and cables and it keeps doing the same thing, when we stop and want to continue the car startle an it feels that the vehicle is going to quit or when it start moving it fells like it doesn't want to run..

    Hasn't been fixed/. I have spent over $800.00 and techs have replace the entire fuel line, the intake valve where the gas tank is, and cannot figure out what is wrong and I have spent $200 in diagnostic fees as well. I am a female, so they start replacing the most expensive parts, and say that is it, and when it doesn't work the want me to spend another diagnostic fee of $120.00 to find something else. I cannot pass the inspection with light on and all they want me to do is keep spending money till they find the cause. I am fed up and hating this. My car has 224,545 miles on it. It has been a good car, but have had the Driver Visor fail, Starter replaced, and have to replace all the lights on car twice a year.
