I hve a new 2010 Edge SEL and when you step on Gas pedal it vibrates until you hit 40 MPH. After that it is fine. I took it to the Dealar and they said it was normal for that model. I find it hard to believe, so with that being said, has anyone else experienced this problem and if so, what was done to fix the the problem. The mileage is at 2,300. Any feedback would be appreciated.
