Stopped in for my usual fill on 1/2/2020 and found the upper-left ring terminal deformed and un-insertable on Charger 1B. Still messed-up a week later, but now there was a piece of plastic broken off inside. I wrote Tesla and told, but as of 1-29 it was still broken, but coned-off.
No huge impact, but it is taking them a while to get it fixed. Will update.
