i have a really long shutdown time, like 600 seconds. One time i got home pretty late around 2am. I went to bed only to be awaken by the door bell 2 hours later and someone told me my car stereo was on. Sure enough it was blasting at annoying levels of volume and had been for at least 2 hours. Only done that to me once of twice thou for an unknown reason. I assume your is constant.
