My 2013 SV GOM at 100% battery has never read higher than 114 miles. Usually at 100% battery it reads 104-108, pretty consistently. Compared with other reports it seems mine is a bit more accurate than 2011 or 2012 models. But there is lots of room for improvement, with better software - such as, GOM remembering your typical driving experience and using that as a basis for moderating the starting mileage reading. But it's impossible for it to see the future so I guess it's okay now that I know what to expect.
What bugs me is that it goes down so fast - as opposed to my Honda Pilot, in which the gas gage doesn't move off of "full" until 40 miles or so - nice if Leaf had that feature!
