One problem related to anti-theft controller has been reported for the 2015 Tesla Model S. The most recently reported issues are listed below.
The main center screen computer began degrading in performance over time (causing more driver attention to be diverted away from driving to deal with functions it controls, as it was laggy and not very responsive). Then, one day, I got into the car to go somewhere and wasn't able to boot the main computer/screen at all. In addition to everything it controls no longer being accessible or working (e. G. Climate control, manual headlights, dome lights, anti-theft alarm, power steering strength, suspension height, etc. ), I also found that I no longer had working turn signals and had to use out-the-window hand signals when I drove to the service center for repair.
