UGH that's not good news. I have this issue too, haven't taken it into the dealer yet because it only happens very randomly. At first I thought it was a dust shield bent up touching the rotor because it was such a loud metal on metal grinding sound but they all seem to be OK. I am mostly afraid it will come back when the weather gets warmer.
Maybe take it to another dealer? if your noise is the same as mine it is NOT "normal high performance brake noise". Also this might sound silly but if you have some time throw it up on jacks, take the wheels off and really check the calipers for rocks/debris I have had the issue before where a small rock got stuck and it made a somewhat similar ungodly noise. That was one of the first things I checked.
I get that same exact noise.. Thought it was just me and my luck... Murphys law is strong with me. If its going to break, malfunction, or something "abnormal" it happens to my car. Already had my rear tires replaced at 7K (fronts are still 90%). I am 45 and drive normal. Had wind issues, had radio issues, brake issues, body panel alignment issues.... Don't get me wrong, love the car but wish I knew of the TSB's before spending $$ out of pocket replacing Fords problems.
