Adaptive Cruise Control problems of the 2022 Hyundai Palisade

I was driving to work, at a rate of 75 mph (permitted speed limit). As I approached an intersection, I tapped the brakes to turn off the cruise control. It did not turn off. I then pressed the brake pedal and it went further down than normal. The vehicle did not appear to even try and slow down or brake. I tried again, standing on the brakes with both feet. At this point, I knew I would not be stopping, as the pedal continued to feel strange, and not catching for lack of better terms. I did my best to steer around two sign poles directly in my path. Unfortunately due to not being able to control speed, I did hit one. I then continued on for approximately and 1/8 of a mile before my car finally came to a stop in the middle of a dirt field. I do not know if this was a software or mechanical issue with the brakes. I only know they did not work when needed, under normal circumstances.

1) front collision sign keep coming up. 2) cruise control does not function. Dealer claims it's wear and tear and maybe due to bumper loose. Claims maybe if someone backed up into our bumper making it loose. 3) display on the front windshield is distorted, which is also camera related. 4) paint on fender is peeling and they call that also wear and tear. Picture attached showing paint coming off overall Hyundai Palisade claims nothing is part of warranty. Everything they are claiming as wear and tear. It's not even 5 years since I bought this car and nothing is covered under warranty.

Cruise control resume function was activated at a low speed after making turn into driveway car automatically tried to resume to 55 mph. The speed at most during the time of activation was less than 10 mph.
