This is also the LTZ 2500 Duramax

I'm new to this group and hoping someone can help me with a fix. My truck has been going through a starting battery yearly, I'm getting a notification that the trailer electrical needs service occasionally, twice so far even when I'm not towing, and in the last two weeks the auto locks are doing strange things like locking the doors instantly when I unlock them, folding in the mirrors even while driving, honking the horn when it locks on it's own. Has anyone else experienced this?
