Yeah sorry for the title but it got your attention. I got stuck in a massive snow drift on the weekend and the whole bottom of the car was caked in snow for like three days. Now after a warmer day i noticed some foul smelling brownish discharge coming from just right of the muffler(towards the center)
Any ideas, frozen vent maybe?

 

You sure your car just didn't get a bad case of diarrhea? (sorry I couldn't resists )

 

That's weird. I never realized how low the G35 sits until it snows. Couple inches of snow & ice and I can hear the bottom scraping.
