My USB/AUX ports seem to have a short in it because sometimes it'll go in & out.

The biggest issue happened on my way home last night. I have a little over 400 miles on the car & as I'm driving, I suddenly hear a chain rattling, squealing noise coming from the rear of the car which eventually escalated to grinding & screeching. It seems to be coming from the driver rear tire area of the car. You can only hear it when you accelerate. I'll call the dealer in the morning but what could this be?

Is your car an A8? If so, maybe it is a Rattle from the Exhaust Variable Displacement Valves? These are supposed to be open upon acceleration but they could vibrate as the NPP valves do.
