Just noticed an unusual sound from my Stinger GT2 AWD when it is coasting. It sounds like a baseball card stuck in the spokes of a bike. It does it in neutral as well. Power seems to make it go away. I had the whole front end up and looked for flapping, rocks, sticks, etc. I shook all the suspension parts and both sides seemed identical. Going to make an appointment at the dealer to have it looked at but wondered if anyone else had any ideas?
