"Service Leveling System" displayed in DIC. Level controls no longer worked. Brought Yukon into dealer. Apparently there is a Service bulletin addressing this issue. After a quick SW update, the Leveling system is working again. Other than that, I've been very happy with the Yukon. Driven over 6k miles so far.
