The 2013 model Nissan Leaf is expected to feature an improved battery pack, and it may be offered as a no cost swap, under warranty for the owners who have reported problems, as well as a stand-alone upgrade for cars without the problem.
Ya, the only place this nugget could have come from is Nissan. I personally think there will be no "improved" battery for 2013 (well, sure, improved like "clean" coal... all marketing). I also think this is a clever plant by Nissan in some interview, or just unfounded, pure speculation by the author. Why would they need to improve the battery when everything is "normal"?
What a great way to shut up the squeaky wheels!!!! "Hey, honey, I was thinking about joining the class action lawsuit against Nissan, but now that they're going to do this, I'll just sit back and do nothing."
One year later, four capacity bars gone, and can't complete the mission it was purchased to do, and resale is in the toilet; "Honey, I don't think Nissan was completely honest with us. Let's reward them by buying another Nissan product to replace this faulty one (or reward them by paying huge bucks to replace the battery)."
