I think this is the key point. In 2012, the ONLY LEAFs losing capacity bars were in AZ, CA and TX, with most being in AZ. Those three states which have some very hot areas were chosen by Nissan as three of the seven states where you could buy a LEAF before the summer of 2011. Unfortunately, August 2011 was the hottest August on record in Phoenix with seven days setting record high temperatures for that day
OTOH, June, 2013, was the second-hottest June on record in Phoenix
. But by then, the issues with the LEAF's battery in the AZ heat had been on the local TV news in Phoenix, so I wonder if both the dealers and the customers had lost their taste for the LEAF in those areas. I'm sure there were still some sales in those hot areas, but I doubt there were as many as in 2011 and I doubt they were the types to flock to this forum like many from 2011.
We have ONE pair of datapoints from an owner in Phoenix who bought both a 2011 AND a 2013:
2011: Mfd: ?, Bought: June 2011, Bar lost: Did he ever lose a capacity bar before trading the 2011 in in Feb 2013? I cannot find a report on Wiki or in the forum.
2013: Mfd: Jan 2013, Leased: Feb 2013, Bar lost: Jan 2014
But it is possible that something was amiss with the battery in his 2013, seeing as it was one of the very first off the production line.
So we have two reports of 2013s losing a capacity bar in only one summer, but not much beyond that. This summer will be the third for some of the 2013s and the second for the rest. Perhaps we will learn more this year.
