I have now fall victim to the aforementioned rattle (flutter, whatever). Mine is a 2012 Explorer LTD.
As mentioned in earlier posts, the sound, emanating from the right A pillar area presents itself in headwinds or strong crosswinds at speeds at and beyond 67 mph, or so. And, the sound is truly annoying and worrisome (at this early stage of ownership).
I've now accumulated 1950 miles of driving since taking delivery on 09/10/12, and I am among those who also experience frustrations with MFT; Freezing screens, lousy navigation (my six-year old Street Pilot 2820 is far more usable) and it often fails to recognize my iPod (even though the iPod shows the Ford logo on the iPod screen).
I had plans to publish a complete appraisal of my experience with my first American car since 1972 (Hondas, Acuras, Toyota's and BMW's otherwise) but I'm holding off long enough to have my local Ford dealer try and make good on my concerns.
Having said that, I was a little disappointed with the CU news. I've never considered CU a benchmark for evaluating automobile performance, but the magazine does have the broadest base from which to draw Explorer owners evaluations and opinions, and those owners opinions are what CU is reporting on.
