I believe the brake or something related to the brakes failed. I ran a stop sign, with no evidence of brake marks on the road. I crossed over a highway hit a side walk almost hit a house. The safety of myself and others was at extreme danger. When finally came to a stop I couldn't put my car in Park, or back in drive or shut my car off, i beleive i had no braking or something electrical failed. My car is totaled. The only light on was the airbag light before the accident.
