Had our 2013 Fusion Titanium 2.0L EcoBoost a little over a month now... 1200 miles. Noticed what I consider a fairly heavy soot deposit on chrome trim around exhaust port (finger black with a quick wipe). I'm guessing this deposit is in the last 400 miles since that's how long since a wash. Presumably the Check-Engine would be on if there were a combustion problem, but, I've never seen a car, running right, with this kink of deposit on the exhaust.
Anyone else see the same thing?
