Warnings problems of the 2025 Kia Motor Sorento

Driving 40 mph coming around a bend. There was a car stopped about to rear off to the left and when coming up around the turn I saw and tried to stop. I was about two car lengths behind the car when I pressed the brake down and I pushed it all the way down and nothing happened. It was grinding and shaky when pressing it down. Not tight or anything. I feel like I normally would have that tension right away to be able to stop. There was no warning or anything and the car always has warnings when something is close.

Driver attn warning randomly goes off frequently for no reason, this malfunction involves the front camera causing this frequent warning for no reason. This faulty issue gives the driver the sense that it should be ignored as it goes off for no reason, this makes this safety system null and void. It is equivalent to the blind spot warning going off so that the driver ignores it over time leading to them pulling in front of a car in there blind spot. The dealer and manufacturer know about this issue but refuse to do anything to fix it, the dealer says it's in the software of the car and they can't change it and kia refers me back to the dealer, it's a frustrating run around for the customer. No it has not been inspected by insurance or police. The driver attention warning feature with a coffee cup began flashing a warning as soon as we pulled it off the lot.
