Default 2012 CTS rough idle

I have a 2012 CTS with a rough idle condition
3.0 enigne with 12,000 miles
I've taken it to the dealer twice fisrt time they told me they could not find any issues.
Took it in today, and they told me all software is up to date, and no codes.
Said that this is an issue with the 3.0. Can anyone verify that this is a known issue.

Default 2013 cts occasional rough idle

I recently bought a 2013 cts 3.0 with 35000 miles. It idles around 700 rpms normally however once in a while at a stop or in park the idling will drop to around 500 for a few seconds and pick back up..just wondering if this is normal or if I should have ot checked..thanks
