Took my Caprice in for scheduled service last week, and have them look at a few warranty items (visors, wheel covers), the big issue was noise coming from the rear of the car. I thought it might be coming from the differential...
Turns out it was a bearing on the the driver's side rear wheel. They replaced the bearing under warranty.
My advice... listen to your car very carefully, especially if it's still under warranty...
I didn't hear it until I put the stock axlebacks back on... the drone was getting on my nerves!
Later,
