Sorry to hear you're experiencing the same thing, but glad I'm not the only one.
I tried to have a service tech listen for the whining noise on a visit to the dealer one day, last year, and got little feedback from them about what it could be. I'm also much less concerned about the hissing...
They basically said they'd have to "start digging around" into what it would be and I have very little confidence in my local dealer service dept. So I opted to hold off and it's been fine so far this year, but I haven't had to use the AC much yet because it hasn't gotten that hot where I am yet.
Something is definitely not right though. When I did use it shortly on a trip about a month ago, it sounded/acted the same as last summer.
I'll probably have the dealer service try to fix it eventually, before it really goes to shi* and it's out of warranty.
Please keep this thread updated if you get any valuable feedback, if and whenever you have someone look into it.
