The vehicle was sputtering and then shut off and would not start. I called KIA and had it towed to Dealership. They called several days later stating there was nothing wrong with the vehicle. Then several weeks later getting on the turnpike it sputter and shut off. I was able to get it started again and repeated the same sputter and shutting off an additonal 2 times on the turnpike. I was able to get the vehicle home to my drive way. The tow truck came and could not get it to start. He towed it back to the dealership. This time they replaced the fuel injector. The mechanic advised KIA that this issued caused scoring on the cylinders. KIA authorized replacing the fuel injector. KIA claimed scoring on the cylinders is normal. You don't have to be a mechanic to know this is. not normal and over time will lead to engine failure. KIA will not replace the engine. My case # is 15929784
A Unknown component has failed with the vehicles fuel system. The service center at the Kia Dealership was unable to clear the associated Check engine light after numerous attempts. This is the Third time I tuned in for this same reason. The First time they attempted to resolve by replacing O2 sensor. After a Few weeks the Check engine light returned.

I've owned this car since it was new. I've been disappointed with the transmission. At low speeds, it will hesitate and shudder. This is especially true if I'm making a turn. This has been a consistent problem. Secondly, twice my transmission has overheated. The first time we were in a Halloween event during the Pandemic 2020. It was a drive-through event that was stop-and-go. The warning light came on with the gauge showing one bar over the limit. As luck would have it, the traffic started to move towards the end and it lowered the bar to just under the overheating bar. The second time this happened it was much more serious. I had four people in the car. We had just left a restaurant and were heading towards the freeway. Unfortunately, we got stuck on a hill in Hollywood Bowl traffic. We were stuck there long enough that my car shut down on the hill. We were blocking traffic and my wife got out to direct traffic around us. I tried to put the car in neutral and coast towards an open curbside parking space. It wouldn't budge. We spent what felt like an eternity blocking traffic. It was probably 4-5 minutes where we were unable to start or roll backward.
