I have the 2011 v6 Premium model and have put 55k miles on it. I have recently begun to hear a rattling sound from what seems to be the front driver side of the car while stopped with my foot on the brake. The sound disappears as soon as I start to accelerate. It is persistent through every gear except park. This sound started at around 52k miles and I have not suffered any braking issues. I had a service guy from a dealership ride around with me and he heard it too but wasn't sure what it could be. Can someone please help me better understand what to ask/tell the dealership?

Oh, and it's an Automatic.
