Yes I too have had the same issue with my GS 350 fsport. They changed the radio free of charge but the problem once again happened 2 months later and this time I could not hear my call which in past I could. So today go to dealer for service my radio apparently is fine and the6 say ma6be it’s a phone issue. Hard to believe what BS. Lexus IS one problem after another. Door actuators on all models eventually go and service every 5k is ridiculous.
This worked for me. Remove the radio from the dashboard to access the power connection. Disconnect the cable that has 2-thick black wires and 1-skinny red wire. Reconnect and see if this fix your issue. This is a hard reset for your amplifier and speakers. 2015 GS 350
