This may not have been your issue, but I'm posting because others may encounter at some point. I have a 2011 EXL AWD V6 (now with about 70K miles), and when traveling across the country in June 2015, my AC quit working about the time I hit the hot and humid southeast. I was able to cruise into a Honda dealer around closing time and they checked the system out. Lo and behold, they correctly diagnosed (after checking all the mechanical parts and pieces) that I had blocked (with boxes and clothing) the air flow (intake) on the passenger front side, which resulted in system malfunction. I'm 98% certain this was the issue, and have never had a problem since then. Have fun. And don't drive like my brother!
