I was able to reproduce the issue. When accelerating from a stop, but not yet passing 7 mph (typically 3-5mph registering on the speedometer), then suddenly braking, the brakes do not immediately engage, but rather engage after several seconds have passed. The system/vehicle is available for inspection upon request. The vehicle did not stop (as the brakes weren't applied) causing a collision. I am able to reproduce the issue in the vehicle. No inspection has yet taken place. No warning lamps or other vehicle messages appeared prior to or following the braking failure and the resulting collision. This undocumented behavior was not noted prior to the failure resulting in a collision. Normal driving conditions would not expose the failure. Limited video is available upon request.
