I have a 2017 1lt RS Camaro and it squeaks on every cold start. So when the car sits for a couple hours and I start it, it squeaks for like 20-30 seconds. Took it to one dealer they said bad belt and changed it... Didn't do anything. Took to another dealer yesterday and they said it's normal. The air pump kicks on to push extra air through and that's what the noise is and it's not a squeaking noise... Sorry but it is a squeaking noise and that doesn't make sense to me. Has anyone else had this issue or have any insight? I called GM and they are going to look into it. Sorry but new cars don't squeak. It sounds terrible on start ups and makes the car seem old and broken lol
