Electrical System problem #1

During normal use, the factory wireless phone charging pad in the center console overheated, produced visible smoke inside the cabin, and melted the charging surface area. No liquids or foreign metal objects were present. The phone was placed normally on the charging pad. The incident created a burning smell and visible damage to the interior trim. The system did not shut down before damage occurred. This appears to be a potential electrical or thermal safety failure in the factory-installed wireless charging system.

Electrical System problem #2

Radio has zero sound - the issue is the radio sound also has the blinker sound, hands free safety/navigation guidance along with the on star safety function. None of that is functional. The dealer states it's a known issue and parts are not available. How can this be when they keep building new units. Gm has been contacted with zero help and no response around my safety concerns. While it seems like a small thing when we say radio I'm not concerned with the lack of music but this system controls way more than music.
