The last few days when I unplug the Roadster it is showing red not green, which normally means a problem but all appears well as I am at a full charge. When charging it shows a blinking red, again I would expect green. Then instead of the Blue waiting to charge I am seeing purple (blue and red). Has anyone else experienced crazy behavior in the charging lights? I am not seeing any error codes or any indication of a problem. But it is disconcerting the behavior has changed for no apparent reason.
