dead A/C in a brand new ZDX EV? Good on you for using your coding skills to figure out the battery disconnect trick. Though sometimes a good old-fashioned reboot is all it takes with these tech-heavy EVs. It definitely sounds like a software glitch, which is unfortunately becoming more common with modern cars. Hopefully, Acura pushes out a software update to address this, because relying on battery disconnects isn't exactly ideal. Keep an eye on it, and if it happens again, definitely document everything and push Acura for a proper fix. It's a premium EV, it should have premium reliability!
