Just curious if anyone else is having the same issue that we're experiencing with our 2nd Gen UMC. We took possession of our M3 almost a month ago and haven't had to charge at home until very recently. When we plug the 2nd Gen UMC into a traditional 120V outlet (GFI), it trips the circuit almost immediately. We thought that there was an issue with the provided charger, but we had another Tesla as a loaner while ours was being looked at and it also tripped the GFI. Since we didn't have any issues charging our S at the same GFI's, I borrowed a 1st Gen charger from a friend. No issues whatsoever charging the M3 with it. Again, just curious if anyone else is experiencing this..?
