NHTSA Complaint #11455332 — 2021 KIA SORENTO

I was on a straight road no cars around the collision sensor went off and slowed me down. Another time it kept slowing the passenger side wheel down as the traction control was going off it did this 2 separate times. Got down the road some and it did it 2 more times but with the driver side. Last week I pulled into my drive way and was in park when it started telling me traffic was coming from the left, like I was about to back into something, I can't remember if I had shut it off at this time due to someone had fell out of the 3rd row when her foot was caught in the seat belt trying to exit the car. I called my nearest kia dealer and was told they were so far behind and since I did not buy my vehicle from them it would be last. I asked if an accident was to happen who would be responsible and he couldn't answer me.
