Just had my truck in for service work before warranty goes off. One of my complaints since new has been the radio shuts off, just out of the blue for no reason, sometimes several times a day or it might go for a month or so and be fine and then shut off again. Recently I have also noticed that when exiting the truck radio was on and when I got back in it was off. Anyway dealer says there's a bulletin that says this is normal if listening to HD. I have to go back as some parts have come in so they can repair some other problems, I'm going to ask for a copy of said bulletin. Just wondering if anyone else has seen this issue.
