NHTSA Complaint #11526350 — 2015 TESLA MODEL S

My MCU (onboard computer system) glitched out and the screen began flickering. I lost all of the Advanced Driver Assistance Systems, navigation, music, phone link, sunroof venting, climate control, including defrost. The screen froze and I had no functions. This has happened 4 times, possibly a 5th time, while driving in the last 6000 miles. I put in a service request to Tesla and they ran a remote diagnosis, and told me that the old MCU1 is overwhelmed by the new software updates. Their solution was for me to upgrade to the newer MCU2 at my cost. I am afraid to drive my car as it will malfunction while I need the safety features, like basic defrost or AC in the 105 degree heat in Phoenix. Tesla acknowledged that the previous MCU1 failure due to the eMMC chip was a recall, but this is a new problem that has not yet been acknowledged by Tesla as a recall problem.
