In November of 2010 my 2007 Ford 500 began to "leap" foward or backward after shifting from park to reverse or drive. This action has continued for the following months. It seems to be happening more and more often. In may of 2011 it "lunged" when I was backing out of my driveway causing damage to both my vehicle and my husbands who was parked near me. I took it to the dealership today after it "lunged" in a parking lot last week almost hitting a child walking by. I assumed it was the transmission. However, I am told it's a bad electronic throttle body and is not covered under the powertrain warranty. I am told it will go out sometime, there isn't any way of knowing when but it will go into "fail safe mode". after searching online I see Ford had a recall on this part that included models older then mine. The problem isn't fixed as many Ford owners are experiencing the same problem.

Our 2007 Ford 500 currently has 63,000 miles on it. At about 53,000 miles we started to see a random "surge" of the throttle when we were shifting the car from park to reverse or from reverse to drive. It has continued to get progressively worse, now occurring almost every time we shift the car from the positions noted above. This is a definite safety issue that Ford needs to address. From all of the online forums, this behavior is not isolated to just one car//one owner but rather seems to be a common problem. Also, on a separate note, our ac failed at 63,000 miles, the compressor needing replacement. Although this is not a safety issue, again this seems to be a common problem.

Ford 2007 500 is lunging forward when foot is on the brake... this began about a year ago. On and off I thought it was bad gas but now that I have used the recommended fuel for my time of owning the car it does it more. Especially when the air is on.. but even when it not.
