Case Number: S1908000102 – Rev. A Release Date: 11/21/2020 Symptom/Vehicle Issue: Audio Mute On All Sources Except AM Diagnosis: Radio mutes and audio does not return even after a key cycle. The radio audio can become locked and muted due to a timing issue. AM band does not use the same timing process as the other modes. Change to AM mode to correct the intermittent concern. Also a 30min sleep cycle will recover the audio. Or, change the source to AM and then back to the prior source to recover the audio. Repair Procedure: Do Not Replace the radio.
