So I am the proud new owner of a 2011 Edge Sport and love it! Have a question though. Last night after a 30 minute drive home from work, I pulled into my garage and turned off the Edge. I immediately heard from what I thought was under the hood a strange whine. I waited for a couple of minutes but it didn't go away. I turned the car on and then off and it and it went away.. Any ideas of what it could be??
