Folks: Before I reach out to Tesla SC, I though I would share my issue. FSD 11.3.6 was loaded on my 2017 X about a month ago. Did not have an opportunity to use it very often but what I did experience on the highway was pretty good. Now the cruise control and autopilot icons are intermittent--repeatedly going on and off. Needless to say, when they are off, FSD and cruise do not work. I tried recalibrating the cameras but that did not help. Has anyone else, had this experience? Is there a do it yourself remedy? Thanks.
