Same thing happened to our 05 HAH. We tried AC for the first time after two owning this new car for two month. No cold air. Took it to the dealer and got disgnosed that road hazzarad (a tiny rock) hit the AC condenser and caused the gas to leak out. The dent is literally smaller than a dime. The bill was $750 to replace the AC Condenser unit. After some complaining and calling Honda North America, I got it replaced for free.

In my opinion, the design is somewhat flawed. My wife and I have owned four cars together. All of our four cars were driven to +150,000 miles territory and never have I had this experience before. AC condenser hangs a bit low near the ground and there isn't much protection from the element.

In my car (I have a 325 Sports Wagon), the AC Condenser unit is completed protected.
