unusal to have so many codes. take it to a pro and he will look at freeze frame data and make a decision as to where your problem lies. my money is on a body control module.
With this many codes it really presents a problem with forming the correct diagnosis approach. If I were working on this, I would record as much data as I could, then erase the codes, drive the car and see which return. Then I would look at the actual problems you are experiencing, and all the old and new code info and devise a diagnosis strategy. This may not help you much, but what I'm really saying is this needs to go to a highly qualified tech that can address computer issues on this vehicle.
