NHTSA Complaint #11470195 — 2021 KIA SORENTO

car suddenly stopped going while driving on interstate, almost like the car went into neutral while driving. It started back again after a few seconds and thankfully I was coming down a slight incline and was able to keep coasting while trying to get off of interstate. I pulled over and it seemed to be fine again so I continued home and when driving up my driveway it did it again and I could not get it to go forward to pull into garage. I was able to put it in reverse and back up and then after that it went into drive and pulled forward but then I tried reverse again just to see what it would do and then it would not reverse and would just rev up like it was in neutral again. I have called 5 Kia dealerships this morning and nobody seems inclined to look at it or to assist me with this matter.
