Good News! There is a TSB dealing with the bluetooth speaker and AM silent mode issue.

The dealer was somewhat argumentative when I re-told him of the re-curring issue today. He tried to say that AM radios are not that good and that bluetooth signals can cut out, and that he'd have to see it. The TSB evidently only deals with the AM mode being silent (speaker issue) and might not address the bluetooth speaker problem. However, I know that if the AM mode goes silent, you can't hear anything on the bluetooth.

Dealer ordered a new radio.
