(Crossposted on facebook) 2015 REX using the Tesla Magic Dock: Each time I use the magic dock, I immediately get a drivetrain error upon unplugging. The good news is that it's not a serious issue and goes away after about 2 weeks... or you can make it go away by simply plugging into a normal CCS fast charger. Level 2 chargers do not clear the error. I'm not sure if this is only an issue with early i3s, but wanted to make sure others know about this glitch as well as the simple fix. On a side note, it sure is nice to have this very rare set of superchargers that allows CCS. It's the only one for hundreds of miles around and in a good spot for a boost in Forks, Washington. It is the only fast charger for about a 150 mile stretch, so it helps a lot.
