I recently bought a Ford Escape four-wheel drive and must admit I am reasonably satisfied, except for wind noise at freeway speed or during high wind. I used to own some cheap Korean cars in the past and the wind noise was not nearly as bad. Ford and its dealers have tried to convince me it is normal..
Without driving your car it's impossible to provide an answer, particularly when noise is such a subjective thing. It's rare to find objectionable wind noise in a car today so I would suspect that something is wrong with yours. Perhaps you could drive another Escape -- perhaps take a demo for a test drive -- and compare it to yours.
