I'm around 15 months into my 16 SS. I have enjoyed this car but have had the whistling noise that starts around 43mph in my ear hole from day one. My dealer finally replaced my drivers side mirror this afternoon. Whistling is 100% gone. It's a completely different driving experience and I've never been more excited about my car. Took three trips over the year to the dealership where they replaced the triangle piece a couple of times. I finally took the panel off on the inside and started playing with the mirror myself. I immediately could tell the mirror was causing the whistle because every time I changed something with the screws and the mounts the pitch or the intensity would change, but I could never get it quiet. Then I ended up stripping out the bolts that attach to the mirror and it was time to get a new mirror. Luckily the dealer replaced it all still under warranty. Anyway, I know this solution has been posted for a while...I'm just excited in what feels like a brand new...higher quality vehicle. Don't accept the whistle if you have it.....so much better with it gone.
