That's quite a list, but I think there's hope. My suggestion would be to approach this in baby steps, find a good dealer shop rep, and tell him, "Look, I know I have a lot of problems here, and I don't expect you to fix them all at once, but let's take a few at a time and get this thing better because frankly I feel like I have a lemon, and I just want it working like other Passports I've driven."
Then I would look at your list and order them from easiest to reproduce, to hardest, because dealers love to say, "Sorry we can't reproducer the problem, and then you end up with wasted time on those." So focus first on the ones they can't deny, and will have to fix.
My order for your list would probably go like this:
1. Memory seats
2. Seat travel distance and adjusting performance
3. AC, they should be able to test how cold it is
4. Proximity key
5. Steering
6. Engine & Transmission
7. Sound
6 & 7 are likely going to be the hardest to reproduce, as it's very possible they simply blame the AT tires, but that's why I'd tackle it last.
