I was coming home this afternoon from work and hit a bump in my car and right after I went over the bump all of my electronics went dead. No music no ac and the gauge cluster went crazy with lights. I've tried googling it but haven't really come up with anything. I went over rail road tracks and speed bumps to try and recreate it and nothing. Does anyone have any ideas? Also I have noticed a slight burning smell when my car is running but can't find it.
