I hope they will not give you answer like they did to me. :::(drive it for awhile, we (dealer) don't have a fix at this moment, but as soon as Ford will realese something we ll let you know). That's exactly words.

I have a gut feeling this have something to do with cooling. I mentioned before, all my symptoms more aggressive after 50 miles round trip or hot day or heavy traffic in NYC.
Colder days approaching and I notice it less.
