NHTSA Complaint #11428811 — 2016 TESLA MODEL X

I had my Tesla Model X MCU replaced per the recall. Prior to having the MCU replaced I had numerous (more than 20) episodes of the car just shutting down and losing all power and would not restart for anywhere from 3 to 20 minutes. Many times after the vehicle would restart the main control screen would remain black, there would be no access to any of the controls usually accessible there. Other times there would be no navigation, radio or HVAC available. When reporting these issues I was told to keep trying to reboot that it was a known software issue. When the recall was finally announced I checked frequently for appointments for a replacement chip which were not abundantly available. When I was finally able to get an appointment for the recall, the service center assured me that the replacement MCU would make things better but I also had the option to upgrade to a better chip for $2K but lose many options like FM and XM radio, which I use. Since the MCU replacement I have continued to have these same issues AND my phone will no longer pair with the vehicle to provide the hands free use I had previously. I have worked with Tesla to try to resolve these issues and I am told by their technicians that this is a known software issue that is happening to "older" Model S and Model X vehicles and there is no current projection as to when this will get resolved as it is on the back burner. My car is a 2016 with 40K miles! How is this OK? How is this not a safety issue? TODAY THE CAR WENT COMPLETELY DARK/DEAD WHILE I WAS DRIVING!!! Luckily I was driving in a parking deck and there was no resulting accident. I have called Tesla customer service and messaged the local service center to report these issues multiple times. Even the corporate customer service rep has difficulty reaching them directly. It is so sad to have such a nice vehicle with issues like this. We have talked about trading it in but ethically cannot fathom passing these known issues on to someone else.
