This scares me... Mostly because of physical contacts deciding to "gum up" with random detritus (metal dust, too hot, oil, whatever it is), more than likely, from fast dc charging & a somewhat "leaky" case that probably has z-pinches starting to pull in some stuff from the outside together with heating getting involved from internal parts. It only needs to not fit the tolerance, just enough, & bing-o bong-o dude, decides to not do the physical contact & the solenoid decides to not move for all of them as a safety feature for the battery packs.
Smart engineering & coding, but it means that that's a default thing in there & it's not telling you with a code.
From what you are saying, in this video, from a condensation issue, a clipped fender panel getting ripped out, random dim light, it suggests a battery case that heats up & cools off & has just enough gapping during actual work that with those vibrations then heating through dc fast charging will force the issue to occur. Randomly. Oxidation coupled with random gunk will do it, or whatever moves the darn physical contacts decide that its too resistive to voltage/amperage, maybe sticky slide area, to the physical contacts themselves, & or all the above.
Software fix means the lowered electrical for the movement part is allowing for it to still retry & "juice it up" to get it to move. They know what the issue is, they just don't want to a recall. So, this video is likely not going to move the needle for them in the buyback because it might encourage people to investigate & then force a class action. More than likely, there are a lot of people who know those issues, with a wide spread dealership claiming not being trained means meetings that suggest they are "encouraged" to not try to accurately replicate these issues & aren't allowed to take it to a proper charger to try.
Which would mean they have "plausible deniability" (not really but it goes to the bosses anyways if it happens) that they tried to fix it & it was just them following orders.
