Having a February 2013 car, I had one of the early chargeports -- it was always "loose" when the charge cable was plugged in. With three successive cables, I had increased difficulty getting the cables to seat, and had to replace the cable (which was dead each time). I told Tesla I wanted the physical port replaced, and they agreed to do it for free, though they wouldn't admit that it was defective. Since then, no problems -- and the port is *much snugger*. I think the looseness in the connection was frying the cables, one at a time Anyone else with an early model S have this happen?
