2021 VOLVO XC90H Electrical System Problems

VEHICLE IN MOTION WITH TURN SIGNAL ON - A LOUD POP FROM THE SPEAKERS IS HEARD - THEN ALL AUDIO IN THE VEHICLE IS SILENCED. AFTER THIS SITUATION, NO AUDIO WORKS FROM EITHER RADIO, TURN SIGNALS, PARKING SENSORS, LANE KEEPING BEEP, ETC. AFTER SHUTTING THE VEHICLE DOWN FOR ~15 MINUTES AND RESTARTING THE PROBLEM WILL CLEAR. BECAUSE OF IT'S INTERMITTENT NATURE, DEALERS ARE UNABLE TO DIAGNOSE - BUT THIS PROBLEM IS IMPACTING MANY USERS - SEE THIS FORUM THREAD HTTPS://WWW.SWEDESPEED.COM/THREADS/SPEAKERS-CUT-OUT-WITH-A-POP-CAME-BACK-AFTER-VEHICLE-OFF-FOR-A-FEW-MINUTES.630447/PAGE-5 - THIS HAS SAFETY IMPLICATIONS AND NONE OF THE AUDIO CUES FOR VEHICLE SAFETY SYSTEMS WORK ONCE THE VEHICLE GOES INTO THIS STATE. PLEASE GET VOLVO TO ADDRESS THIS PROBLEM SERIOUSLY.
