Hi Zemaker. I had an issue that my car could not get past update 36.2. I contacted TESLA and they told me the car's firmware was blocked and would need a Service center visit. Then I received a call from local dealer and he was able to force update through. I received V42.4 and the new features of V9 are great compared to V8. My only issue is that I do not have the summon feature showing up in Autopilot. The tech said they will look into it and get back to me.
