Wow. I am seeing all my same issues so thought I better enter my info as well. First the horn was all of a sudden blaring without anyone being in it in the middle of the night 2. 5 years ago and now I do not have a horn, and none of the controls work on the steering wheel including the radio and cruise control (I question if the air bag is active on the driver side because of this). Then, the rear lift gate all of a sudden will not open (maybe last winter). 6 months ago, the indicators on the dash are out so I can't see my odometer or anything else you can access on the dash. Recently the passenger side window just randomly fell off the track. Recently, everything on the driver's side door does not work electrically: power door lock, and power window. And I find that gm will not address at a minimum the electrical issues? not good.
