Had a very disturbing incident last night. My Model S was charging in my garage when my smoke detector went off. I ran to the garage and saw plumes of smoke coming from the Tesla Nema 14-50 adapter. The car was still charging! I unplugged the charger from the car and yanked the charger adapter plug from the outlet. The Nema 14-50 adapter fused to cord. The adapter had a hole on one side where it was melting. I called Tesla and they sent out someone with a new mobile charger and nema 14-50 adapter. I am not sure how i feel about using this adapter again. The breaker never tripped nor did the car generate any error or shut off charging. I had the electrician come out and inspect the outlet. It showed no signs of charring and tested out fine for constant voltage within specs. Not sure how I feel about Tesla's response at this point. I plan on calling them in the morning.
I just felt like i should post this to make others aware. Hopefully this was just a case of bad luck in getting a bad adapter
