Consumer Description

On July 4th 2023, I was driving with my son in car, when unexpectedly the check engine light came on and car lost power. We were on a highway with a 65mph speed limit. I was able to pull over to side of road. Car did Start back up, however was missing and misfiring. Shaking especially under acceleration. My engine has been consuming oil for many thousands of miles, it is documented; however only an oil consumption test was performed. Hyuandai and Kia has serious engine issues and they know it. This could've been worse. Luckily I still had some brake pressure to get off the road. With this stalling on the highway, it is very dangerous.
