I'm joining the battery replacement club. I lost my 4th capacity bar on 4/14/2014, having driven the LEAF as my primary vehicle for almost 3 years. I had learned of the 2013 warranty being applied to the 2011/12 models about two months ago (not exactly up on my LEAF news, I know). I wasn't sure what to expect, in terms of capacity loss, whether it was a linear decline, accelerated, decelerated...just figured I'd have a good chance to qualify for the replacement with 2 years and 12,000 miles to go at the time.
My work commute is about 70 miles roundtrip. From the beginning, I charged the LEAF to 100%. For the first 2.25 years, I was able to drive my 20 miles surface streets and 50 miles freeway commute with just charging at home (240v schnieder electric). Then, I needed to charge at work (on 120v) to make it to work and back. Currently, I charge about 7 hours at work to be at full bars...returning home with between 2 and 3 bars.
I didn't really track when I started to lose capacity bars, but think I lost the first bar after about 1.25 years and 20K miles. I lost the second bar within a few months of the first. The third bar, well, I don't really recall when I lost that, but it was within this past year.
I had a couple of outstanding recall notices on the LEAF, so I took it into the dealership this past weekend (Nissan of Simi Valley). I asked about the battery replacement program, which they've heard of, but have never done one there. After doing the recall fixes/updates and battery performance test, they agreed that I was eligible (probably) for a new battery. Nissan service now needs to call "Tech Line" (their term) to determine exactly what they need to do next. They have asked that I bring my LEAF into their service department when they are on the phone with Tech Line, so I have a scheduled date/time this Wednesday for that. I assume, if I'm cleared for a battery, I'll be scheduling an appointment for the battery swap to take place, and have been told that I'll likely get a loaner car while this is happening (depending on if Tech Line says it's okay for a loaner).
It's very early stages right now, but so far my experience with the service folks at Simi Valley Nissan has been favorable. I'll ask them about the "hot weather" battery pack voucher program, and report back here after my next visit with them.
