I have caught my car making this odd noise from time to time and was able to get it on video. The car is off and had been sitting for over 2 hours. Any idea what or why it is making this noise? I have no check engines or other notices in the car. Everything seems to be fine...

I can't hear anything in that video except a dog barking.

Glad I stumbled upon this...mine is making the same noise!! For me, it happens after long rides on hot days (when I'm using the AC). I've read various things on other forums, some point to the AC Compressor, others mention the alternator. Still unsolved. No driveability issues.
