Noticed this as I was driving home after taking delivery, there is a slight but noticeable rapid pulse type noise which can sound a bit like a hiss coming from the front passenger door mid-range speaker when moving at speed. The noise is slightly less apparent in a right turn, slightly more apparent straight and in a left turn. It appears to be tied to suspension movement. I mostly notice it at highway and freeway speeds >50 MPH. The noise is worse if the road has some texture or is a bit rough, not so much on a fresh smooth road. I wonder if some electrical noise from the MagneRide suspension operation is getting in to the audio system. Radio volume does not matter. Its not bad, but now I hear it I always hear it.
I hope GM has a Service Bullentin out of this, I have very little faith in the hand tied dealer service techs, especialy when it comes to warranty work, in finding electrical issues. Anyone ever read or come accross a similar problem?
