This happens to me too. Glad to hear I’m not the only one.2022 Tahoe - our liftgate button on the outside of the liftgate...about half of the time, it only unlatches the liftgate, the liftgate doesn't fully open. I've been very deliberate about not pressing the button oddly and it's still doing it. I press it a second time and it opens completely. Our 2021 AT4 never had this issue and we put over 40k on it in a year.
