My car is 2.5 years old and 48k miles and my AC starting blowing warm air out on the drivers side vents. This lasted for about 4 weeks until a hissing noise started coming from the middle AC vents and the entire AC system started blowing hot air. The dealership wouldn't honor my limited warranty since I'm over on the mileage. After much resistance and discouragement from other mechanics who advised me they didn't know how to fix whatever the issue was, I was forced to bring the car to the Honda dealership, who was charging me $300 just to DIAGNOSE the issue! Within an hour I received a call from the dealership that my AC condenser was leaking and Honda was extending my AC warranty to 10 years, since they're seeing this issue a lot lately. I would not be responsible for any repairs to my AC! By the end of the day I was driving home in a car with cold AC.
