I was driving the vehicle and came to a stop sign. When I accelerated to turn and drive what was a steep windy downhill Road my car jerked some and the check engine light battery light and oil light came on the dash when I went to push the brakes they went all the way to the floor and the car did not stop. I continued to try the brakes and had to use the emergency break to pull up and down to stop and drive up on a hill to not crash into other vehicles I have my vehicle at Kia and they are claiming there is absolutely nothing wrong with the vehicle and I am to pick it up and leave the lot. They have not offered a loaner car or shown any concerns of my safety leaving the lot. I have asked for it to be in writing, but my car is safe to leave and they are not doing so this has caused major anxiety and PTSD to even begin to drive myself and my children are very shook up over this.
