While listening to music from USB the complete user interface locked up while doing 150 kmh on the highway. Not fun. Both displays were 100% locked, no speed indication etc. Also systems like indicators, autodrive and light failed. Power, steering brakes all seemed to work though I did not have much confidence in anything at that time. While driving into a petrol station the system did an reset on its own and seemed to work fine. The day before I had to reset twice to get the map to display. As the USB music was stuttering the whole day I day I got the idea it has something to do with that. Anybody any advise? Other than writing an email to Tesla and not getting an answer? I don't like to call roadside assist for issues that are not urgent.
