Last week while driving, my AM station sound went silent. Tried other AM and FM stations and still no sound. Turned off and on the radio knob, no change. But when I switched to Sirius XM there was sound. After arriving at destination I turned off the engine and restarted the car but there was no change. No AM/FM sound but had Sirius XM sound. Went shopping for about half an hour and when i came back and started the car, all sound returned. Anyone else experience something like this? Purchased my Limited late January 2019. Other than this sound issue, only other problem I’ve had with my car is the rear power gate issue, the dreaded three beeps, twice.
