My 2016/17 model S was working flawless until I got an email from Tesla that they need to upgrade and retrofit the autopilot computer . After scheduling, rescheduling the appointment 4 times ( they could not get the part) last week they showed up and did the upgrade . Since then my cameras stopped working , and worse the map and gps do t work anymore . The map is frozen at one spot . After rebooting the computer 4-5 times I tried calling service but could not go through. So tried the chat service . She ran a diagnostic on my car and said that the car can not connect to any of the satellites. She scheduled another technician to come in 9 days , pissed that I had agreed to do the upgrade in the first place , I said sure . The next day I get a message from the service department that the problem requires the car to be taken in at a specific day chosen by the service center . Don’t even get to decide. Now I have to take a day off to take the car in for a problem they caused . Does anyone else have these issues . When I bought this car , Tesla had excellent service , now you can’t even get a human being anymore .
