Turn Signal problems of the 2017 Tesla Model X

The mcu (media control unit) also known as the infotainment center went out on my 2017 Tesla Model X. When this unit went out, I lost the ability to use the turn signals, the back up camera, most of the controls to change settings for the car and the car was no longer able to accept a charge. The car was in the driveway at home when this happened and I tried to schedule an appointment with Tesla to get this resolved. They told me that the part was on back order and that they could not take the car in at the time. It would be about a month before they were able to get the part and that I could still drive the car. They also asked me to keep the car charged but I also let them know that the car is unable to do so at home. He asked me to take it to Tesla supercharging station and try there. I let them know that my turn signals were no longer working and the technician told me that hand signals were still an acceptable form of vehicle direction/movement indication. Well, I took it to the supercharging station with the turn signals and rear camera not working and the car would not charge so I had to take it home again driving without turn signals on the freeway. I finally convinced them the car was not safe to drive and that the car would lose all its battery reserve before I they were able to take my appointment so the technician asked me to drive it into the san francisco Tesla service center.
