Radio/tape Cd Player problems of the 2015 Chevrolet Silverado 1500

Upon turning the vehicle on there were no alerts like seat belt warnings, door open, hands free calling, onstar. Also when shutting vehicle off no alarm to indicate keys are in the ignition. Cannot hear if blinker is on. Nothing comes through the radio. This happens on an intermittent basis. Approximately every several months. Sometimes it will start the sheets if I shut the vehicle off then start it back up. Today it didn't do that. At this time my truck has approximately 80,000 miles. Also on occasion the service electric breaks have indicated an issue as well.

All sound stopped on my truck. Radio, turn signal feedback, etc. It was working at end of day but did not work the following morning. I searched and found recall #14315 but your web site says there are no recalls for my vehicle. It has exact same symptoms as described by that recall. I googled symptom and found where someone had disconnected battery for awhile and that fixed it. Did for me too but feel the fix in recall 14315 should be applied to my truck as well.
