Has anyone noticed small white and black particles on the inside surfaces of their 2015 Focus? If you look on the dash, you can actually see the little flecks of white and black. It is not normal dust or dirt. I don't drive with my windows down and don't use dirt roads. I am wondering if the car is recirculating dirt from the floor when using the air conditioning in the Max setting, since this circulates interior cabin air.
