2022 Hyundai Tucson brakes problems

I was driving down the highway going about 60-65mph with cruise control and LKA on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my Forward Collision Warning would say something if my Adaptive Cruise Control isn’t on (or is and I’m just going too fast to slow down) neither of those things happened. No warning.

The contact owns a 2022 Hyundai Tucson. The contact stated that the tailgate independently opened while driving. The tailgate warning light was illuminated. Additionally, the wheel well molding had detached. The vehicle was repaired at an auto body shop. Additionally, the contact stated that there was water intrusion into the headlight housings, and there was a sharp plastic part coming through the rear seats. The vehicle was taken to the dealer and was repaired.
