I own a 2015 LS Camaro. Since i got it, it made a very faint whistle sound. I always figured I was just hearing things and would ignore it. After a while it got a bit more noticeable and I assumed there must have been hole or crack where there must be air coming into the car. Now the sound is very noticeable its sounds like a loud hissing and mostly happens when I rev past 3RPM. I took it to my dealers service department and they said they didn't hear anything and couldn't fine anything wrong with the car. My problem with that is I have many people say they hear it too so I know its not just me. Has anyone else experienced this or have any idea what it might be?

 

Welcome to the forum.

Can you record the sound and play it back for them?

 

I've been really busy with work lately but i was able to take a video a few days ago.
