I have the same problem. My radio light stays on. You can't tell during the day, but at night you can see that the light dims, but it never goes out. I'm still trying to find a resolution, but I take the fuse out that controls it. It also controls the power locks and other things, but at lease my battery is not always dead when I need to be somewhere ASAP. I'm getting a computer diagnostics done on my car in two days because I'm having other computer problems. I'm going to ask them about that issue as well. I'll get back to you.
