So I picked up my car today and I am noticing ugly black dust all over the back of it. I am assuming its break dust blowing through the cooling vent and coming out the back of the vents? My car only had 6 miles so I doubt the breaks were broken in..?
Thoughts?

Sounds like it may be running a little poorly. If the fuel mixture is off the car can blow soot out of the exhaust. This will likely remedy itself once you get some more miles on the car. The ECU is in a learning phase. It is adjusting your fueling and mixtures based on ambient temps, elevations, etc, etc.

Or it could just be just dust kicked up from driving you can create a pretty good vortex back there.....
