If I push hard, I get more resistance at first but then it slowly sinks toward the floor as a I continue to press. If I push softer then it just sinks toward the floor. I still have plenty of stopping power. If I push the pedal repeatedly then it builds up more resistance ("pump the brakes") but then the resistance calms down and it becomes mushy again.

I was driving down my street (one way) at 20mph when all of a sudden, the car veered to the left and smashed into a dumpster that was parked on the street. I had driven down my block several times during the day and was aware of the dumpster. I am convinced that the lane assist malfunctioned and drove into the side of the dumpster. I was not distracted and my brand new, 2025 Hyundai Kona was totaled in the accident. I had minor injuries but could have been much worse. I am not sure who to contact to report this and not sure it could be proven. Any help you can give me I will appreciate.
