After 30 minutes talking with the manager he recomended to contact gm directly and ask them to tell him to change it, and he will aprove to change the supercharger.
i contacted gm and i have been waiting ......the custumer rep has been really kind even if she is not in the mechanics, she is trying to find out why they say that the rattle is normal.
does anybody knows in florida about any gm dealership aware of these issues that already did change any supercharger?
any good idea?

Your dealer needs to read the new bulletin closer #13313.
It says in black and white, the condition is - rattle at idle.
The correction is - replace the supercharger.
Part numbers are provided and a complete decription of the changes made to the new supercharger including a solid coupler.
There was and old bulletin saying the idle rattle noise was normal. They need to read the new bulletin. Reading is fundamental as they say.
That motorauthority article is a little out of whack too. The 10 yr / 120,000 mile warranty is from when the car was purchased new. Not from when the new supercharger is installed. That fact is also in the new bulletin #13313.
