“While driving, the vehicle audio system intermittently loses all sound for approximately 1-2 seconds. During the audio loss, entertainment audio, turn-signal click sounds, and vehicle warning chimes all disappear simultaneously and then return. Vehicle is currently running infotainment software version 662.11. Issue occurs while driving and has happened multiple times. Concern is that loss of warning chimes and turn-signal sounds may reduce driver awareness of safety-related notifications. …”
