There is a newer version of the charge port door part. I had washed my Model 3 shortly after I got it and then I started getting messages that the charge port door needed service and it would also randomly open and close when parked. Tesla replaced it with the newer version of the charge port door which has more robust seals and I’ve been ok ever since. However I never experienced problems charging like you did.
I was thinking the same thing, but then if the piece was missing altogether, wouldn't the car think the charge port was open all the time? And why would that then prevent charging when the door is open?
More disconcerting... WTH is with Tesla (ineffectively) gluing/taking parts together on this car? I'm still kinda dumbfounded by the vanity mirror falling off of the Edmund's car.
I know adhesives can be used effectively in automotive applications, but when you F it up and parts start falling off, it looks real bad from a quality standpoint.
