Anyone had there rough idle fixed 

The dealership acknowledges the rough idle is there but says no codes or lights so it’s normal. Have gotten GM involved and they are no help never returning calls or helping much

Rough in park or when stopped in drive?  If stopped while in drive, my 2017 suburban had new motor mounts installed tsb 17NA166 and it smoothed it out.
