@mzhang2018 Only you can answer those questions. You're right, your issue does not seem to be isolated. Take a look at this thread, if you haven't seen it yet:

AC Condenser Problems

The car is about two years old. The AC does not work. The air comes out is not cool at all. It seems there is no refrigerant in the system. Perhaps there is some leak in the AC system. I will bring it to a dealer next week. I will report their diagnosis.
The two about-ten-years-old Honda cars in my family have never had AC problems. It seems it is not rare for 2017 Forester to have an AC problem. Does this mean I have to buy an extended warranty if I'd like to keep this car? Does it mean I should go back to Honda again or try Toyota when I purchase my next car? ......
The mileage of the car is about 15,600 miles.
