Same problem.... I use my adapter 1 month, now, every time I charge, the same error pops up "charging adapter fault" in the car and the charging speed is limited to 17-18 kilowatts. Tesla support does not answer, sellers from the Tesla store do not answer ... what to do is not clear because I live where there is no Tesla service center... If some one know how to fix the problem, please let me know...cheem.ulei @ gmail.com
