That's a pretty accurate description, yeah. I think I'll let it be for the time being. I plan on taking my car by the dealer in the next few months to get it looked over and talk to someone about a few small issues before the warranty expires. And no, it's definitely not an engine knock. To me it sounds like something loose behind the head unit or somewhere around the middle of the firewall. I can live with it; it's done that since day one.
I have that same rattle in my 2014 V6 6spd.
