One problem related to software has been reported for the 2021 Volvo XC90. The most recently reported issues are listed below.
*with the bowers & wilkins sound system* twice within 1400 miles, there was a loud "pop" sound from the speakers followed by no sound from any portion of the vehicle. The pop sounded like a window or the sunroof shattered. All sound was lost: sensus feedback, turn signals, parking sensors, phone, etc. The only thing that worked was the bass. After the car was parked and off, and re-started, everything worked as normal. Oddly, there was the feeling of static electricity just prior to each pop. These pops were caught on dash cam for proof. There was static heard in the dash cam video too. The dealer provided a "fix" with a software update described in technical journal. Tj 35554. 20-2020 (ihu volume restrction with orange key). This software update had nothing to do with the problem I had. The orange key was no where near the car during any occurrence. Since the update, there have been several identical loud pops, but the audio continued working. The same static electricity feeling occurred milliseconds before the pop. All incidents occurred while on a freeway or merging on a freeway, with my phone on the wireless charger and the audio on at least around 50%. Multiple reports of the same issue on a reputable Volvo forum.
