I have a punch-list with my dealer for multiple things that don't work... Adaptive cruise control, passive door locks, "key missing" upon re-entry, rear lift gate not opening 30% of the time, car shaking >65mph....
the rear lift gate issue is real.
our 2022 did it and our 2023 is the same way...when the liftgate hasn't been opened all day and the first time it's "opened" using the button on the outside - it'll only unlatch the lift gate. a second press of the button and it opens fully. any other time after that initial opening and it opens as it should
