They replaced the pin and chargeport door.Does that pin act directly on the connector or does it pass through some plastic plate/locator. I wonder if the locator is at a to high tolerance making the pin jam or not allowing the full travel rather than the pin itself making full travel or retraction. Most linear pins usually have a good amount of force behind them, only when you induce a non linear force like a sheer movement that could be a simple location or vanity cover misaligning or with the cold, closing the engineered tolerance of the path of the pin. It wouldn't surprise me if a simple reaming of the pathway or a new plastic charge housing from a slightly different material totally cures the problem.
Aparently there is a revision of the part because this is so common in earlier Model 3s.
Im going to give it a bit of time and then update everyone to see if this fixes the problem.
