Update:
No appointment tomorrow. The front springs are on back order, but the swaybar end link nuts came in. Service manager hopes that the springs will be here in a week. Reschedule then.
Original problem, whine under the hood, appears to take a back seat until Chevy/GM engineers figure out the issue and formulate a fix. I was told to keep driving the car as it won't cause any long term problems.
