All I know about the latch is I hear it click when the seat goes forward and back. When going back, I definitely hear the click/latch well before the seat stops moving, so it need not go back as far. In fact, I can manually adjust it forward once it goes back all the way, so it should be fixable in software.
I thought leg crusher mode had gone away insomuch as when someone is sitting in the third row, second row seats wouldn't go back as far. Not so. My 44" tall son complains about his legs getting crunched every time - so I have to stand there and tap the seat button to prevent said crushing.
