Not really unless you have another problem under the hood. If your concern is Carbon Monoxide from Exhaust, check your manifold gaskets (this is where the manifold meets the engine) and be sure they are not leaking.
Common odors emitting from your vent can be Must or Mildew from a dirty Air Conditioner, and this can be solved by buying a simple vent cleaner from your Auto Parts Store of choice. You may also smell Antifreeze if you have any leak - minor or major. It steams when on the engine block and has a distinct oder. Also, you may smell oil if you have a bad valve cover gasket and minor to major leaking.
Out of all of these, only the Carbon Monoxide is harmful. However, in cars 1996 and newer, a leak this bad should illuminate the MIL lamp (Check Engine). Your O2 sensors may see the leak and try to adjust fuel mixture in vain, tripping a Check Engine Code.
You can get your Check Engine light read for free at any Auto Zone, but they are not allowed by law to reset it.

AnswerWater vapor will sometimes exit your car's vents when hot humid air passes through the A/C cooling system too fast for the condensing moisture to form into water droplets.
