Today I had to slam on my brakes to avoid a collision. Once I stopped, my car would not move when I stepped on the gas. I discovered my brake pedal was stuck to the floor. I tried putting my car in park and back in drive but my car wouldn't move. A kind stranger tried to help me push it with it in neutral but it would not move. After about 7-8 minutes, the brake pedal popped up on its own while my car was in drive & started to roll. It seems ok now. I went to the dealership & they said it sounded like my ABS locked up but not to worry unless it happens again. This makes me a little nervous. Does anyone have any input?
