I first noticed this a few days after I had the car. The call audio would cut out and the music would come back on for a second and then drop out again, allowing me to resume the call. It's basically unusable. Happened again the other day, so I decided to dig deeper. Here's a video of just the BT settings screen, and you can clearly see it disconnects twice in the 26 seconds I filmed. I've restarted the phone, re-paired the phone to the car and rebooted the MUC, but it keeps doing it. If I go to the BT setting on the phone, I can see it match the reconnect events (which makes sense). Tesla has scheduled a service appointment for me but I'm not convinced this is a hardware issue. If anyone has additional suggestions, I'm all ears -- the service center is not super-convenient for me so happy to avoid if possible. FWIW, BT was never an issue with my previous vehicle, with the same phone/apps/software version.
