I disagree with the original post. I am glad that I was able to buy my 2011 here in Phoenix and glad I could buy a new replacement when I was forced into getting another car. Only a few other manufacturers are willing to sell EVs here so I am glad that Nissan continues to offer them. Perhaps dealer/manufacturer disclosures at time of purchase/lease could be emphasized more for people who are not familiar with the car. I signed disclosures indicating battery deterioration is expected at the time of purchase of both 2011 and 2015. The capacity loss on the 2011 was much faster than expected, but Nissan retroactively offered a 5-year, 60,000-mile capacity warranty (long before the class action lawsuit became public). Nissan EV Customer Service called me and asked me to take the 2011 to the dealer so they could start the process of getting a new battery installed at about 26 months after purchase. The battery in the 2015 is doing much better since it has more capacity after 38 months and 59,000 miles (currently at 10 capacity bars) than the 2011 had at 15 months and 14,500 miles (at the time of the Phoenix Range Test in September 2012).
By the way, the 2011 was extremely reliable until it met its demise and the 2015 continues to be quite reliable.
