New Uconnect Issue - Buzzing Sound

Well, I don’t have the TomTom reboots anymore(OTA Map Update). But a new issue has started happening. This has only happened twice, so far. Upon starting the vehicle, the Uconnect screen stays black and a loud buzzing sound comes through the speakers. We just got through a trip(over 10 hours of driving)Labor Day weekend and everything worked flawlessly. Since being back home this issue happened. It’s actually pretty startling to say the least when it happens and makes me think something is going to break. I have not waited to see if the buzzing sound will go away on its own. Shutting the vehicle off and then turning it back on fixes the issue. Going to disable Car Play in the iPhone Bluetooth settings to see if that is the culprit as that was the only thing we enabled before the trip since it was still disabled troubleshooting the TomTom reboot issue. Also going to turn off the built in wireless hotspot since it has been left on since the trip. So those are my next troubleshooting steps. So basically for a couple weeks everything has worked great, up until now. There are some threads on some different forums and some seem similar to my situation, but no resolution.
