I am now approaching 300 miles on the odometer. Took my Sky out today for about 50 miles of back road twisties. Some road was a little rough, but most was not. Midway we began to notice an irritating rattle in the dash, even on pretty smooth roads. It seems to come from the drivers side and or the center vents. Then, I noticed some vibrating noise from the panel between the seats which is not too bad. I had hoped that GM had worked the bugs out on the Solstice. If anyone has experienced the rattle, Solstice or Sky, let me know. I am planning to take it back to the dealer.... but I hate to have them tear into my dashboard.
