I had Tesla perform the MCU1 -> MCU2 retrofit last year. However, my MCU2 rebooted 3 times while driving the past week (once on 2020.48.30 and twice thus far on 2020.48.35.5). It usually takes about 90 seconds or so to turn back on, but obviously it's not fun to drive with both the IC AND MCU being fully black. At what point do I actually try reaching out to Tesla service? Or do I chalk it up to buggy software builds? I'm curious to hear from others if MCU2 crashes are common.
