Latest overall stats from the Wiki:
"Even though there have been 105 documented cases of battery capacity loss of one or more bars (as of 9/29/2012), only 50 capacity loss cases have been reported to Nissan to our knowledge. The geographic breakdown of these cases is: Arizona - 52, Texas - 23, California - 26, Hong Kong - 1, Spain - 1, Unknown - 2. The breakdown by number of capacity bars lost is: one bar - 68, two bars - 26, three bars - 9, four bars - 2. Based on the approximately 450 Leafs sold in Arizona as of September 22, 2012, at least 11.5% of Arizona Leafs have lost a capacity bar. Since only cases reported on the forum are included in this calculation, the real number is likely to be much higher."
For those of you updating the Wiki for capacity loss, please remember to change the overall stats each time you do, and not just the specific bar loss table:

Also, there are two entries (Kristy Bryant - 3 bars and Josh Bryant - 2 bars) that don't have entries in the earlier tables. I haven't added an entry to the earlier tables for those people, as I don't know when they lost their earlier bars. As a consequence, the total of 105 cases is currently 2 larger than the number of one bar losers. If vrwl or anyone else wants to add those dummy entries, or has a better idea how to handle this, let me know.
