I think they use the same glue that is used to attach the windshield to the frame of the car, some sort of Urethane, like DOW-U-428 or similar. At least that it what it looked like and how difficult it was to cut. Only by putting a *lot* of tension on it (read: a pry bar in the cut to force the enclosure apart) and a sharp break-off knife cutting the glue right next to the pry bar, was I able to *cut* the 2013+ packs open. This often distorts the top lid, so not recommended when you'd need to re-close it. But almost always I was just harvesting the modules, to be put into a 2011/12 pack that is entirely *bolted* closed. Nissan wanted to have some protection against opening with standard tools, so the service disconnect is (on those packs) bolted to the top lid with security Torx. So yeah, it is not trivial to inspect the inside of a 2013+ pack. Not sure how a dealer services such a battery, probably a whole day's of work for just replacing one of more modules in a pack, so I can see that they really want to avoid working on a pack.
I don't know if the official Nissan safety precautions still double the man-hour costs by including a second person standing with a rope in hand, tied from a distance to the mechanic working on the pack, ready to yank his twitching body away from the danger after touching the wrong bits. (and yes, that is said as mocking humor - I am EE and I always work on the Leaf packs with steel tools and bare hands, the only reason I never received a shock is because I am aware of what I am doing at all times or I would not be working on them *and* I tend to verify isolation using my multimeter. I absolutely recommend against this practice for everyone not fully aware of the dangers of HV, but this is what I am comfortable with. Don't do this at home. Stunts performed by unprofessional actors or something to that effect.) Cor.
