So occasionally while driving the whole dashboard lights up and kills all of the accessories. How if you hit the steering wheel they will turn off but will eventually come back on. Does anyone have any idea what would cause this to happen? Thanks in advance

This happens to me as well. I changed out the ignition switch and it still persists. It has been suggested to clean up the mega ground relay under the center of the main console. You have to pull back the cover down near the floor. I haven't tried it yet but, I will let you know if it works.
