The windows fog up so bad that it becomes hard to see. The vents spew out the pungent smell of anti-freeze. I have noticed on more than a few occasions that puffs of vapor shoot out from under the passenger side dash and vents. I know that anti-freeze is poisonous to humans and don't think that its safe for me to be driving the vehicle when I have to breath in the vapors.
