This has been mentioned before, but I started this thread to directly address it. According to the warranty, you can't drive, or even transport, your S outside of the US and Canada. Mexico seems the most likely place people would want to visit, but crossing the border for dinner potentially voids your warranty. With on board GPS, this might be a serious threat. From the Tesla warranty: I don't understand the rational for this at all. Mexican power is identical to US and the car must protect itself from bad power to avoid problems with brownouts, generators, etc. I'd think the conditions in some of the Canadian territories would be a bit harsher than in many areas in Mexico as well. Does anyone have any notion of what this is all about? It's mostly a theoretical consideration for me, but I'd think people in California and the South West would have some concerns.
