NHTSA Complaint #11578775 — 2023 KIA EV6

For about 6 weeks, after driving the car for more than 2 minutes, turning the car off and then coming back into the car within several hours (like when picking up kids from daycare, grocery shopping, going to restaurant, etc) results in no sound regardless of source, including ALL alert sounds for collision, blind spot, cross traffic, literally any and all sounds inside the car. Resetting the infotainment using the small reset button does not work. Unplugging and then replugging any fuses does not work. The only solution is after the car is turned off for several, typically 4 or more, hours. This is incredibly dangerous not just for the alerts, but because it renders Bluetooth calls impossible, resulting in having to use the phone manually while driving after trying to disconnect the Bluetooth connection. Others online have reported needing the amp replaced in order to solve the problem.
