I have a high pitched whistling (think Tea kettle) that occurs, randomly when the vehicle has been running for a while, or may start right off the bat. The whistling will stop when the brakes are applied and will not start again until you accelerate. no issues with braking or acceleration performance. Mechanic said - no safety issues but doesn't know what is causing the noise. Anyone have any ideas?

This is probably related to a vacuum leak. It may be the brake booster, so have your mechanic disconnect and plug the booster vacuum hose and see if the noise goes away (do not drive with this hose disconnected). Check all the vacuum hoses on the engine as well. Let me know what you end up finding.

I had this exact same problem. It turned out to be the intake manifold gasket that needed replacement.
