Wow! Just a note of sympathy for you on this issue. If you're left holding the bag on this, Nissan is really not acting appropriately nor even in their own best interests. I'm well aware of Blink's history, but to blame you for using a Blink is very poor form for Nissan, especially in the absence of any warnings from Nissan or, as you've said, no exclusions in the warranty.
I'll be watching this closely and rooting for you.
Thanks, I'm crossing my fingers! Hoping to get another update Wednesday.
