I am in Nevada…..well today the fourth bar went….now to 8 on my 2012 with 27k . My warranty expires in December, I am getting 60 miles on the clock after charging, but it quickly decreases to the 40’s after just a couple of miles of travel. Would you suggest to wait after the hot summer or have it done right away. I have adjusted to keeping my distances in check. Do you know if Nissan is replacing the packs with the 2017 models? And will waiting be beneficial to getting the newer packs? Do the newest packs have a name to ask for?
