FYI, I have a 2020 XLT MAX. I frequently carry a "truck vault" style gun box that mounts over the folded down 3rd row. When I do this, I pull the 50A fuse that controls the 3rd row seats AND the auto-fold on the 2nd row. I do this so that there are no circumstances when the 3rd row tries to open while I have it literally tied down with the truck vault.
This fall when I went pheasant hunting in SD, we had 3 hunters, 2 dogs in kennels and all of our gear. For extra space for the trip I removed the driver's side and middle second row seats. No issues no errors, no codes. BUT, I had already pulled the fuse controlling motion on all 2nd and 3rd row seats, which is probably why there were no codes or errors.
I've since reinstalled the seats without issue. If anyone else does this, note that if you have a center seat, pull the center seat FIRST. It will make it easier to pull the outboard seat due to trim shingling. Similarly, reinstall the outboard seat(s) first, then the center seat. Note to everyone who hasn't done it yet, get a 55 mm Torx "PLUS" socket, which is different than a standard 55 mm Torx.
