My PNW 2013 LEAF is also over 100k miles now and it's still clinging to 11 capacity bars. I have noticed that LBW now appears at 21% rather than at 20%, so I suspect that's actually triggered by a GID threshold rather than by an SOC value. Also, the 80% charging feature is now a 79% charging feature
Other than that, I likewise have some front end clunking with my LEAF. Not sure yet if it's the lower control arm bushings, sway bar, or a tie rod end. Hopefully not the latter.
