Just checked, same issue if I put it on Defrost/floor. On full hot everything blows hot, and on full cold everything blows cold, only on medium heat (and slightly colder) does this happen. On a moderate day like today you get cool comfortable air out the top and hot air out the bottom. Also if i turn it to dash vent or defrost only (no floor) I still get warmer than desired heat out the floor vents, not blowing hard, but enough that it can get uncomfortable. Doesn't matter if it is on recirc or fresh air.
I talked to Subaru customer service (not the dealer). They agree that this is not right. The dealer however is trying to tell us that it's normal. Just wondering if anyone else has run into this.
