I'll second Joe's concern. From the vague "technical note" that was posted, I gather that Mitsu added a "Contact test" and CHAdeMO makers added that test, but the tests aren't compatible. Older models aren't affected because when asked by a modern charger if they support the new test they say "WHAT new test?" and the charger says "Never mind, go ahead." With a new i-MiEV, on the other hand, the car says "Sure, I support that test," gets gibberish back from the charger, replies with error messages or its own gibberish, and the charger says "You FAIL." This all sounds pretty stupid, but it's stupid in exactly the way high-tech stuff can be, so it also sounds plausible.
For me personally, a 2012 owner, this scenario may have no effect, but if I'm misinterpreting the note and the reality is that OLDER i-MiEVs will fail the test (it's just badly worded enough that this interpretation is possible, if IMHO unlikely), that would at least be mildly irritating. I do know my car works with Greenlots DCQCs installed here a couple of years back, and I have no plans to take this car out of this city (I'll dump it if we move back to colder climes), so I suppose that less favorable scenario doesn't matter a lot either.
By 2016, I was no longer recommending the i-MiEV as a new car choice (Mitsu had made the car a joke with little/no future prospects and dubious support), though I did think the rare used models were definitely worth a look at their bottom-feeding prices. On that score, anyway, my conscience is clear.
Still, this is a TERRIBLE way to treat customers who paid good money for the 2016 cars, especially since standard CHAdeMO was a major selling point, and Mitsu really owes them a solution for this; if it's not just software, the hardware can't amount to much. I realize a class action lawsuit by the literally dozens of 2016 buyers [sigh] may not seem much of a threat, but the reputational issues could unexpectedly explode far beyond the cost of any fix, especially if the takeaway headline is "Mitsubishi makes lousy EVs with non-working quick-charge ports."
I really hope this gets resolved, and I hope someone can give us some good news here.
