Not saying it will drop in time, but it is possible. Mine should be dropping the fourth bar anytime. LeafSpy stats are listed below.
The vehicle was manufactured in January 2013, spent it first two years in Georgia, was auctioned after lease return and brought to Las Vegas. I got it in March 2015. It dropped the first bar in October 2015, the second bar in June 2016, and the third bar in November 2016.
