This is a 2010 3.5 SEL with 10,000 miles. I'm getting a slight vibration while driving at highway speeds only when I'm on the pedal. As soon as I take my foot of the pedal and coast the vibration goes away which pretty much rules out any wheel or tire balance issues. The vibration is slight but noticeable. I can feel it through the wheel and seat. I have not taken her to the dealership yet but wanted to see if anyone else has had a problem with vibration. I was thinking it has to be engine, trans or driveshaft vibration. Being a new Edge owner, I'm not yet sure if this is a common problem.
