What is the software/firmware update everyone is talking about? I have a 2015 Yukon XL Denali that rides rough. I have asked about TSB stuff at my dealer and they say nothing doing.

I had both front struts replaced at 56k miles. Just got told they are leaking - 50k miles later. Ready to delete MRC.
