2026 BMW X3 xDrive30 audio, ADAS and parking assistance disappeared simultaneously

Today first the audio (carplay, FM radio, indicators, usual beeps) completely stopped working. Shortly afterward, I got a Driver Assistance failure, followed by Parking Assistance becoming unavailable.

I tried the 70s iDrive restart by holding down the volume knob, but that didn't fix anything.

I then parked the car, locked it, walked away and left it alone for about 30 min. When I came back, everything was working normally again (audio, driver assistance and parking assistance).

I'm guessing some module/software got stuck and the full vehicle sleep/reset cleared it, but it's pretty disconcerting on a brand-new car.

Has anyone with a G45 X3 experienced this?
