I had a 2020 Denali and it had a warning for tailgate open as well as inner tailgate open
i just traded in the 2020 for a 2023 Denali ultimate and I only have inner tailgate open warning
not sure if it’s not working or gm took away the option of tail gate open warning
this sucks because it’s very easy to hit the button by accident when you’re reaching in the centre console in front of the gear selector to get something
