Bummer. Mine is still holding onto settings. Must be a difference in software revs. I've been a technician for almost 30 years (not automotive), working with all kinds of equipment that runs firmware/software, and the one thing that is consistent is: manufacturers make a product and leave it to the end user to figure out where the bugs are and then correct it later. Some companies are better than others, but very few do THOROUGH pre-release testing. It's unfortunate, but I've also made my living chasing these flaws out of equipment. I'm sure there will be a release from GM that acknowledges this flaw and a fix at some point. At least it's not like my new Toyota that was destined to leave me on the side of the road due to a failed fuel pump (of which they have zero to replace it with due to global Denso shortage)
