I'm also having charging issues, but somebody mentioned that when charging at home, the problem could be the car's on-board charger too. Therefore, if you already went thru 2 cables, I'd ask Tesla to check the car, to eliminate that as a possibility. In my case, charging was stopped almost immediately upon pushing the dongle into the charging port, with the screen just saying 'charging stopped'. But in reality, it never started. I tried FIVE times, and same thing. And the 'TESLA' LEDs were always on. After doing it slowly one last time, the mobile cable 'box' finally clicked twice, and it charged normally after that. And I noticed the 'clicks' happened after a second or two, not almost immediately, so not sure what was happening with my car that was rejecting getting charged before the relay had a chance to 'click' twice. I just plugged the car now, and it started charging like always, so not sure what's going on.
