I drove for about 30 miles today before my Hazards came on, on there own, and wont go off. I shut the car off for about an hour and a half and then proceeded to have issues starting the vehicle. The brake pedal was very stiff and it didn't want to turn over. I finally pushed on the pedal as hard as possible and it started up. The lights still won't shut off though. I dont know what the issue could be.
