I'm not trying to nitpick, I really cannot tell and don't have context or pre-existing knowledge to resolve it for myself and I'm not a native speaker either:

Do you mean "No Leaf has active cooling", or do you mean "No, Leaf has active cooling" (with a comma)?

Because I suspect the comma version, because I think the no-comma version would probably have been formulated slightly differently?

The reply you're responding to was a rebuff of the original parent to the thread - so it should be read without a comma i.e. it is correctly written.

You could write it as:

"Not a single Leaf has active cooling" or "None of the Nissan Leaf's have active cooling".

The above two alternative sentences aren't as elegant or concise as the original, hence why it was likely chosen.
