The service dept is typically a huge profit center for an auto dealership so their mailing programs are geared around getting you into their svc dept so they can inform you about additional potential items they can service at your wallets expense(pun intended).
I also agree that you go to the closest Nissan dealer that has a leaf tech & have your stuff handled there
