“While driving at highway speed, the brake pedal suddenly became completely rigid and could not be depressed. The engine continued running normally, there were no warning lights, and I had to coast into a parking lot because I was unable to brake normally”
“The contact stated that while driving 70 MPH, the Service Brake Assist warning light illuminated, and the brake pedal became difficult to depress. The contact exited the first available exit and coasted to the side of the road”
“Was parking and the brake went hard without warning. Using both legs pressing as hard as I could, but the brakes would not work. Had to tow this to a repair shop - No warning light at all”
