Does anybody know how complicated a "charge port" on a Model S is? I don't. Without knowing that, its hard to judge whether it is reasonable for it to fail at 100k miles. To me, it looks like Tesla should cover this via "goodwill". Why? Well because its mission in life is to get people to adopt electric vehicles - how much does it move that forward for the car's charge port to cost $1000? Its not a part that does anything while the car is moving. And it has no moving parts while the car is charging. But both Model S cars I've had have had their charge ports serviced. When I brought my 2015 home I could not open the port. Tesla told me to bang on it with the heel of my hand, which I did, and it finally opened.
I guess I just think of ALL the parts on the car they should have over-engineered to the point it would last literally forever, the charge port should have been near the top of the list. And Tesla should be humiliated and apologetic when one fails. But that's just how I see it. The OP has my total sympathy.
