NHTSA Complaint #11531696 — 2014 KIA OPTIMA

Today, 7/11/23, I was traveling on the interstate with no issue. Upon exiting the interstate up a slight hill, there was one car in front of me, I let off the gas and began to roll backwards I hit the brake and didn't think anything of it at first. The car in front of me pulled forward and I took my foot off of the brake and began to roll backwards again, I hit the gas and nothing happened, during this I also heard what sounded like a clunk noise. At this point I put my flashers on and looked at the dashboard, I saw three lights that have never appeared before. (Oil light, battery light, and check engine light) I placed the car in park and sat for a moment. The car was still on but not running, I pressed my start button and the car turned over the lights went off and I drove about 3 miles down the road to a lot. Once the car cooled I checked the oil and the level was fine no smoke nothing strange. I went to pull out and drive again and the same exact thi g happened again. However, a few hours later my fiance drove it home and had no issue. If my car had rolled back I could have hit someone or been hit. It's something unknown and is dangerous. This all just happened today and it has not been taken anywhere yet.
