Well at least on the east coast. All the Nissan dealers level 3 charges are broken in one way or another (Some now over a year) and there is only a vague ideas on when they will get fixed. From the looks of it, I'd say that Nissan has been screwed by Sumitomo who seems to have totally failed in making reliable charges and along with AeroVironment completely botched being able to service them.
I've never really fond much use for the Level 2 charges as it takes to long but the Level 3 charges were most helpful in extending the range of my Leaf. Hopefully, Nissan will wake up to the problem and get a fix, or at least, sue till they get some of their money back. Ultimately Nissan needs to either develop their own L3 charger or buy a company that makes them so they can control what is going on. Hundered of thousands spent on installing these things and look now.
Also, they need to get them out of the dealers. These Bozo's are for the most part either clueless and even hostile to EV. Take a page from Tesla and install your own branded charges in stand-alone locations!
