Own a 2011 Suburban that has experienced many of the symptoms described. Is this litigation complete or ongoing?

I recently got a 2007 Yukon Denali. After a week it started knocking. The knock was due to piston slap .I've spent over 2000.00 on this truck in repairs so far. I need to know does the class action lawsuit cover this 2007 Yukon Denali .It has the 6.2 Vortec engine in it.
