My 3 year old leaf is 12 bars. There were issues with heat in the SW but I've not heard of anything recent to indicate your statement is anything but a petty smear on another BEV. Also battery has a longer warranty than 5 years.
While anecdotal evidence is useless, its also laughable how hard Tesla owners here are trolling the LEAF.
I think you would be quite surprised how many of us Tesla owners are/were Leaf owners, so be careful what you say. My big issue with Nissan, why I would never buy another car from them, is how they didn't stand behind their EV product when the batteries started to fail. It took a Class Action suit to get a capacity warranty out of them. My 2012 battery was down to 65% after only 40,000 miles/4 years. I would NEVER buy another EV without thermal management, unless there is some huge breakthrough in the chemistry. But, people up north seem real happy, as do people in Norway, which shows that its purely a heat related issue. And, as someone else said, there are stories of Leaf owners who just missed the 5 year/60,000 mile capacity warranty by a few days or miles, and Nissan denied it.
I just found out today that my Leaf's intermittent passenger airbag issue requires a new $2000 seat to replace the faulty occupant sensor in it.
