Todd, it's nice to hear that someone from Ford is willing to look into this.
I purchased a (used) beautiful '08 Ford Edge Limited with every bell and whistle. I love everything about the car, but soon after I purchased it I noticed the high pitch noise. I brought it to the Ford dealer to get the problem looked at. The mechanics heard it right away and commented on how loud it was. They believe it is the fuel pump that is making the noise.
However, from reading on the owner boards, even if I got it replaced with another Ford fuel pump the noise might stay the same. Apparently many of the Ford fuel pumps for the Ford Edge has this issue, and getting a new one to replace it is no guarantee that it will be better.
This is the first American car I have purchased and I really love the car, everything except for this noise. It makes the noise constantly, regardless of whether the car is moving or not. It is so loud and shrill, the only way I can drown it out is to turn up the fan to it's highest setting and/or turn up the sound system to a pretty loud volume.
Oh, and the Ford dealer? The mechanics checked another '08 or '09 they had on the lot, it made the same noise, so their conclusion is that it's "normal" for these cars.
It's puzzling, to say the least, and has really hurt Ford's reputation in my eyes.
It's too bad, because I love basically everything else about this car. It really is excellent! But if I don't find some way to fix the issue, I will probably need to sell it or trade it in for a loss. And if the issue doesn't get fixed, there is a very small likelihood I would consider a Ford again.
If Ford stood behind their product and addressed this defect, I would be overjoyed, because I really would like to keep this car!
