2025 Kia Sportage Hybrid

Two occurrences. First, it was sprinkling rain when breaking before a stop sign at an intersection near my job, with no stop for oncoming traffic. I drove over a bump and it’s as if the car got confused and didn’t want to stop. I had to release the brake and slam on the brakes to stop. Second, same situation different location and no rainy weather. Hit a bump while coming to a stop light at the intersection and it was as if the car lost traction and couldn’t grasp correctly to break safely. Instead it felt like it skidded to a stop.

The highway driving assist in my vehicle turns off without warning. It’s having control of the steering and speed but randomly even when the hands are on the steering it switches off with no warning. Because it has control on the steering it tries to adjust even if we are to move it a little, But when it disengages there’s no warning or indication. This is a dangerous and it needs to notify the driver when ever it’s disengaging. It either needs to have a warning or needs to be disabled by Kia through a recall. This seems to be a common problem in Kia vehicles as reported online. Kindly look into the issue!
