Hey all..so I bought this cobalt from a dealership and they completely screwed me I think..I had problems with it since day one, months ago it actually stopped working and had no boost or anything, so they patched it and now its making a weird sound when the car gets warm it makes a loud whining sound like as if a brake shield was rubbing or something..anybody got any ideas what it is or have the same problem??

 

belt rubbing maybe?

 

nope its kinda like metal on metal?

 

check to make sure your lugs and everything are tightened? when i changed my suspension a few days later the wheel lugs got loose casuing this really annoying metal on metal rubbing sound?

 

its out of the supercharger i think though..was told may be a bearing in the supercharger or something like that
