When I bought my Model S, I put in a 240V/50A plug so I can charge faster. The mobile charge that came with my Tesla has been plugged in for seven years without any issues. Last week, I noticed a strange smell, like burning plastic when my Model X was charging. When I searched the internet, there were posts about a failing 12V battery emitting hydrogen sulfide gas. However, my Model X has a lithium-ion 12V battery so that should not happen. Anyway, last night we discovered that the smell came from the NEMA 14-50 plug. It looks like one of the prongs on the charger melted the socket. Strangely, the car was still charging at 40A, which is kind of scary. I stopped charging and unplugged the charger from the socket. Not sure why the 50A breaker did not pop on the electrical panel.
So, in addition to all my health issues and other problems, I have to get someone to come out and look at my charging circuit. I hope the actual wires and circuit are okay, and I just need a new plug. Likely I will need a new charge if the circuit is working as something caused the plug/socket to overheat and melt.
