2017 Hyundai Sonata brakes problems

The sensors for braking did not work. I had an accident where I rear ended a truck. The brakes didn't work, only slid into the back of the truck. I was on a busy street when an emergency vehicle turned on sirens at the last second. The truck stopped as it should have. I braked as hard as possible but the car kept going until it collided into the truck. I have read reports on the 2017 sonata which states the car will stop when it senses imminent danger. This one didn't.

Tl* the contact owns a 2017 hyundai sonata. The contact stated that when it snowed, the anti-lock brake system engaged, the vehicle pulsated, and took 30 to 50 seconds to stop. The contact had no control over the vehicle when the failure occurred. The contact stated that the failure occurred while driving more than 10 MPH in the snow. The manufacturer stated that if the dealer indicated that the vehicle was designed that way, then they could not assist. The failure mileage was 6,000.
