It's a 3.8, right? Is the sound only on the first start of a very cold engine?
Used to read a lot about oil filters with bad anti-drain back valves. That can make an unpleasant start up sound.
Turn the key to on but don't start yet. Let the start-up systems-check lights cycle through. When that's all done, start the engine and watch very closely for the red oil pressure warning light (red oil can light). If the filter is draining you might see that light flash for just a brief moment.
Good news is you can change the filter without doing a whole oil change.
Another screech can be the PS pump when it's very cold, too.
