Of course every time I try to take a video, it doesn't happen. I was thinking the same thing with the a/c clutch. I'm going to try and get it in to the dealer soon. I'll report back with their findings.
I have almost the same thing going on. At cold start-up I'm hearing a belt chirp. Doesn't happen every time though. The compressor also kicks on very hard at idle and it almost feels like a misfire. I wonder if its related to the chirp
