There are two different Ecopia's that I am seeing. Ecopia EP422 PLUS and Ecopia EP422. The Plus is advertised with a Platinum Pact Warranty while the other has a 65,000 mile warranty. The Plus has a higher load range an is the same diameter 24.88 in however the Plus is rated at 837 revolutions per mile compared to 833 for the plain Ecopia. The Plus is $10 cheaper at Costco than the "Plain" version though the name makes it appear that your getting something more.
Further checking on the Firestones web sit indicates the Plus has a 70,000 mile warranty so the Plus is an additional 5,000 miles however the greater revolutions per mile make it appear that it has more cush or rolling resistance so range per charge on the Leaf may be reduced. While the regular Ecopia tire is listed as $4 more at Firestones store than at Costco they have a $70 rebate (via a Visa Gift Card) on a set of 4 which is doubled if you use their charge card.
All that said the OEM Ecopia on my 2014 S with 17,000 miles on them look more like what I expect at 40,000+ miles from OEM tires on vehicles from other manufacturers that I have owned.
I have been getting the $99 lifetime alignment from Firestone on my cars and they will check and realign the car (if it needs it) every time you bring it in for a check even of its monthly for as long as you own the car. If Bridgestone insists on a ridiculous alignment schedule then get the lifetime alignment at their own chain of Firestone service centers and then let them pay their own people to recheck it every 6 months to keep the warranty in force.
More on topic at Sam's Club my daughter has received a full set of 4 tires at no charge twice on the road hazard warranty. At Sam's they do not have the Ecopia but Leaf owners there claim the Michelin Eco that they replaced the Ecopia with gave them better range. They do cost about $60 more per tire than the Ecopia and the warranty is only for 50,000 miles.
