It's related to the A/C belt which is probably why it's happening now during warm weather.
Well I finally just got around to taking the car in last week for this issue. Apparently the dealer said all of the A/C pullies and the belt need to be replaced. All parts had to be ordered from Germany because there are NONE in the US. Expecting a call from the dealer within the next 5 to 7 days when the parts are to arrive, and it will be a days work.
