I have an 06 Ltd coupe. I have started having problems with the radio/CD player not shutting off when I exit the car. It happened the other day when I went to a store so I purposely left it on. It was still on when I came back to the car 20 minutes later. I took it to the dealer yesterday and of course the answer was they could not find any thing wrong with it. I proceeded to show the technican what was going on. His comment was yes there seems to be something wrong with it-end of discussion. Has any one else had this problem? If so, what was the solution?

Thanks
