So the saga continues. Auto-pilot went out again, after being fixed at the Service center by the technician with his laptop. So I went back and read this forum about TeslaFi webApp and also iPhone App Stats. So in the morning deleted all the Tesla iPhone apps on my iPhone except the Tesla App, and changed my Tesla account password, and then cleared my token on TeslaFi and changed the polling value, and then relogged into TeslaFi. I then got in my car to drive home from work around 7PM, Auto-pilot was still off, and then on the drive home it came on and everything worked again! I really think now the problem is related to TeslaFi and polling too frequently. I don't think it's related to the iPhone App Stats, I do iPhone development for a living, and the App would have to employ a background network task to keep itself alive to poll the Tesla Network. Plus if you force close the Stats App the back ground task would be killed, so I doubt Stats is doing anything to cause this problem. TeslaFi however is gathering tons of data and polling frequently, and if it were to set some JSON value wrong during a request it could cause problems, that's not to say Tesla's API doesn't have issues too which it probably does. Anyway, someone should tell Tesla about this. The data on TeslaFi is starting to add up now.
