Might want to correct the title "Missing welds, Nissan to replace 211 2014 LEAFs". Nissan will inspect 211 LEAFs, any with missing spot welds will be replaced. They won't necessarily replace all 211 - it might be very few that get replaced.
Good that this was caught in a quality inspection, self-reported, and a recall self-initiated. Bad that it happened, though. Seems like the Smyrna roll-out of LEAFs has been more trouble-fraught than usual.
