I don't think so, because when I turn the radio off upon hearing the noise it stops. The noise is also occurring when the "Service Theft System" shows up on my DIC, though sometimes it does not. The best solution right now is just turning the radio off when exiting the car.

I haven't actually noticed a ton of noise coming from the steering shaft... though I'm sure it's still an issue because the steering seems a little sloppy compared to a '04 SLS I was driving the other day. Until the noise starts to really bother me, I'll leave it as is.

I did forget to mention I have the shimmy. It starts at 66-67MPH and does it all the way up to 75MPH, though 72MPH is the sweet spot where it levels out. I'll get my dealer to balance the tires at my next oil change, and that should solve it.
