My car has been glitching big time lately. First when I make calls, I can hear the people but they can't hear me. Then one day my heat seatersand heat stayed on all day while I was at work which I think normally shuts off and then I was driving using the auto pilot and although the voice was saying veer right, the car was veering left and I had to grab the wheel and take over not to miss our exit lane. Soon after this the hazard lights went on and won't tun off. I called Tesla support and they said the car has a new software update that has been trying to download for four days and that that would fix all the issues the car was having. I cannot connect my car to my home wi-fi as the range doesn't reach and it won't let me connect to my phone or my son's phone which I use as a hotspot...it tells me the password is wrong but it is not wrong. Will the software update be able to download without a wi-fi connection? Any other ideas on how to download this software update to fix these glitches?
