On Sunday Sept 4th, while attending an Edge Addicts track day event at Circuit of the Americas in Austin, My 2017 488 Was parts of the run group, 2 laps were completed prior to the brake pedal failing completely to the floor and causing my driver to loose all braking capability and slamming into a wall. We have in car video from Go Pro footage, footage from another vehicle from behind my 488 and also footage from the control room of the track. This vehicle was purchased 3 months ago, the brake fluid is at the correct level and the new "Recalled" Brake fluid cap is installed. There is some sort of serious manufacturing defect with this system, this is a car designed for this type of use. This needs a serious investigation before others are hurt or killed.
