I don't know how to describe this weird noise but I've captured it on video. 3.5 hybrid with about 54k on the odometer. No codes, no lights only happens randomly. I have a theory that it only happens after the engine cools completely but I'd love another opinion. Sound "seems" to originate at the back of the engine compartment. Reving the engine a little seems to instantly stop the noise. It never lasts longer than 20 secs.
