As I was driving at 12 am today, I pulled into a McDonalds and when I was under the street lights my automatic lights (drl, dash lights, heating and ac) all turned off and would not turn back on. When I opened my door to get out the car made the chiming noise like my lights were left on. Does anyone know why or what caused this? Also, my horn went off by itself earlier in the day if that may have any ties. Any help much appreciated!
