Maybe everyone knows this already though I'd guess it will be news to at least a few.
The liftgate on my 2019 GTR is adjustable. Meaning, I can adjust how high it opens. When we took delivery, the person who did the inservice with us told us this but I didn't do anything about at first and did not remember how it was done. I'm not very tall but have needed to duck just a bit to avoid hitting my head or at least getting too close for comfort. I looked in the manual but could not find anything about this. There aren't many buttons back there so I experimented. On my electronic liftgate, pushing and holding the liftgate close button while it is open for a few seconds will trigger a few beeps. Adjust the liftgate up or down to suit where you want it to end while continuing to hold the button and once at that location, still holding the button, it will beep a few more times and should now be set to open to that height.
