I know exactly what you're talking about. Before mine was totalled, I had the exact same issue. It's the passenger side window pillar panel (to the left of the windshield when looking at the front of the car). I brought mine in under warranty for this. Even though I told them EXACTLY what it was, it still took them 224km and 3 days of road testing to diagnose and fix the problem. They packed the panel with some insulation and the noise was gone (until about 145km/h).
However, suspecting that the techs at the dealership would in fact take my car for a joy ride, I reset the max speed on my GPS and hid it in the glove compartment. They took it to 156km/h. I brought this up with the service manager and got a VERY sincere apology. I would have pushed the issue further, but the the GM is a bit of a family friend, haha.
