2015 C7 - Weird Rattle Noise under hood... see video
I’m having a weird problem, any help would be appreciated. I have a rattle from my C7 when lightly accelerating. Definitely appears to be coming from under the hood possibly the engine. I attached a youtube link from someone who caught it on tape. Appears to be from under the hood. Has anyone else had this issue? I have around 9k miles on it..
Listen to the video around 17 seconds in...
Thanks!

I heard it. If I'm listening to it correctly, I think it sounded like someone wrinkling aluminum foil. Didn't do it all the time. Did you isolate it to a certain RPM?

That’s exactly what it sounds like. It seems to happen around 1500 RPMs and only during acceleration. It does not happen all the time. Usually seem to notice it most between 30 and 60 mph.. The second I let off the gas stops..

Is there any update to this? Mine just started this and is sound exactly the same as yours. Only under acceleration and only around 1500RPM. I was informed that it is most likely the tension pulley going bad but did you ever fix yours? If so what was it?

I'm hearing a similar noise under the same conditions. Wow, now I have a warble in the rear and a crinkle in the front. This car is a real gem.
