OMG ours has just started doing that. I went to get a blanket from behind the back seat and when I pulled the back down I heard a man say a word. I looked around LOL. It has happened about 10 times now. We figured out it is the radio. I guess we should take it in. We just came from having the entire transmission module replaced and 2 recalls done. 18k miles. Uggh. Now this.I have only had my 2019 Titan a month. Any ideas why the radio comes on intermittently. Truck will be parked looking pretty and then all of a sudden the radio will come on for a quick second but today it lasted a lot longer than usual. Any ideas what I am looking at since this is my first "Big Boy" truck ever?
