engine/coolant odor?

[cx-7driver1]

I have a 2009 CX-7 that I purchased Oct. 2008. I noticed immediately that there was an odor inside the car after the engine was warm and first thought it was a new car smell. Then I noticed it only occured on warm days, and forgot about it as it stopped occuring in the winter time. Now that it is warmer outside it is beginning again, I drive about 200 miles a day and by the end of the day the odor is in my clothes.
Any ideas? The local dealer hasn't heard of this before.

Mold in the AC/heater ducts is a possibility.

go see the threads under the cx9, it took a long time, but I believe it is fixed (coolant odor present)
