the first 4th bar loss has been reported. it appears there is no flattening out of the degradation and instead a steepening of the curve.
August 31, 2012 - LEAF owner Scott Yarosh is the first to lose 4 of the 12 capacity bars, for approximately 33.75% - 39.99% total battery capacity loss. He has scheduled to return his leased car to Nissan on September 15, 2012. His car was sent to the Nissan testing center (at Nissan's request), in Casa Grande, Arizona in July 2012 with several other customer LEAFs. The battery was removed by Nissan, however no repairs were made or promised. Below is a table with the number of battery capacity bars missing on this car, the percentage lost, date, miles driven to date, and months in service.
1 bar - 15.00% to 21.24%: Apr 07, 2012, 20000 miles, 10 months of service since new
2 bars - 21.25% to 27.24%: Jun 07, 2012, 23800 miles, 12 months (3800 miles/2 months)
