Electrical Problems?

Hello...I am hoping someone can help shed some light on a problem(s) I am having. I have a 2006 Azera that I bought used about 2 months ago with 19K miles. So far, I love the car but I am starting to have electrical problems. When driving, my dash lights and head beams flicker at times, mostly when I am coming to a stop (sort of like a short or something). Also, the sound went out a few times on my radio...it goes out for a few minutes, then comes back on out of no where??? I am also experiencing some hard downshifts when coming to a stop. I don't have a clue if these 3 problems are related or not, but they all just started to happen over the last week. Does anyone have any ideas???

Thanks...Michael
