Good and bad news... our 2019 pre-recall-fix is having the same issue. It seems to have started since the software update that limited charging for safety.
Bad news, no one seems to know anything about it or if there is a fix or if it is a hardware or software failure.
Good news, I have a workaround that works, but is rather a PITA.
You are right that the issue isn't the latch itself, but the locking pin behind the latch. The pin should lock the latch in place during charging to prevent inadvertent disconnects, but for some reason it decides randomly every couple of days to lock when there is nothing plugged in, thus preventing the cable from being fully seated.
We've tried every possible easy solution under the sun to get it to unlock, but we've found only one PITA solution that works... pulling the 12v, waiting a minute or two, and reconnecting it. Fixes it every time, and is a complete and total pain... good reason to make sure you have a 10mm in your car at all times.
This did the trick for now, will take it in to Chev to get a full fix.I cannot plug the charging cable into the charge port of my (post-recall-fix, 2019, LT DCFC) Bolt.
The problem is the metal "latch" at the top of the charger (see photos) is stuck in position, and physically blocks the top plastic prong on the charge cable. The charge cord cannot get far enough in to click into place. The latch itself seems to be locked in place by a metal prong coming in from the top left.
I think this is meant to be the mechanism that locks the charger in place when the car is charging, but now it is locking the charger out of the port.
I don't know what happened. One day it worked, the next day it didn't.
(I tried lots of different charging cables, and it's definitely a problem with the car's port not the charging cable. I only tried L2 chargers, but I assume no kind of charging cable would work. I turned it on and off a few times and nothing changed. I tried prodding it with a plastic stick and that didn't do anything.)
