NHTSA Complaint #11424425 — 2017 TESLA MODEL X

The MCU screen (large touch screen in the center of dashboard) has been malfunctioning. This started a few months ago when screen seemed to "crash" -- as I'm driving, the screen will turn black and take a long time to come back. On other occasions the map won't load and I receive a notice for "network error" (and have 5g service and not a satellite problem.) This would happen on and off for the past few months. I reported it back in March and was told they would order parts and get back to me and haven't. Then the 12 volt battery died and they replaced it but the MCU problems didn't go away. The last time I drove it, the screen froze up, then turned black and didn't come back on. The collision warning, lane assistance, and adaptive cruise control and steering all stopped working. I COULD engage the auto pilot and cruise control (the notification showed on the small dash board on top of the steering wheel, that they were both engaged) however, they didn't work. I set the car to 65 on the highway and the cruise control wouldn't go over 50. Also, on the back roads, the car drove straight through stop signs without stopping.
