It's up at http://www-odi.nhtsa.dot.gov/owners/SearchResults?prodType=V&searchType=PROD&targetCategory=A&searchCriteria.model=LEAF&stats=1837814%2C2%2C2%2C32%2C12%2CLEAF&makeStats=&jsonBaseURL=%2Fdownloads%2Ffolders%2F&searchCriteria.model_yr=2013&searchCriteria.make=NISSAN&searchCriteria.prod_ids=1837814.
Under (currently 4) associated documents, I see a letter from NHTSA dated March 11, 2016. I've briefly looked at the PDFs, but it confirms the change from service campaign to a recall and I see a mention of Transport Canada (Canada's equivalent of NHTSA, AFAIK).
It affects:
MY2013-15 Nissan LEAF (ZE0) built between November 19, 2012 through July 31, 2015.
