On the first long trip in my new 2010 Sante Fe SE AWD I noticed that my back was hot and sweaty. I checked to make sure that the seat heater was off and concluded that the material is just not breathable as in my cars of the past (Honda, Ford, Infiniti, etc). Apparently that seat material/design is just not good for me. The longer I drove, the more uncomfortable it became. Anyone have any suggestions? I will look into after-market seat covers that may provide some air flow.
