Same and I have one to replace next week. This particular wall connector is just shy of 3 yrs old.
So so green
That my friend will be a warranty issue with manufacturer not installer, past the 1 year mark. Reach out to Tesla or have homeowner do so, that is if you don't have time to swing by just to discover it's the Wall Connector and not your wiring.
I am Tesla EV charger "certified installer", being on their website gets you about 2 or 3 hits a day sometimes of homeowners shopping for pricing.
I can't tell you how many ppl compare prices based off of the contractor that actually job walked it and not use him.
Sorry lady I can't give you a price if I don't know what I'm looking at, and your panel load calcs don't allow the capacity to charge your car that fast.
Either slow down the charge rate (lower amperage) or upgrade you electrical panel.
Trying to low-ball me on a $495.00 Nema 14-50R install when you just spent around $60k on that EV makes me be off that Tesla website. No thanks, too much time wasted on providing ho's install options with very little profit if any.
