“All of the lights on my dashboard come on and when this happens it's generally night time. I can't drive my car with the headlights on because if I cut them on my car won't move and my rear view camera will not work. The first time this happened it was 05/18/2019. I was driving in the evening hours to pick my son up from work I noticed that the car started to slow down as I had my foot on the accelerator, I pulled the car to the side before it stopped and turned everything off. I waited a few minutes cut it back on and every light on the dashboard was on. …”

“Driver experienced initial bogging down on acceleration before normal acceleration occurred. There have been two occurances thus far. Happened while one foot on brake and the other on accelerator in order to get rapid response changing lanes in traffic and other while making left turn through traffic. Very dangerous to experience bogging instead of acceleration. This was a recall problem with my 2011 jeep gc. Replaced an internal fuel pump relay in the tipm that cured the problem. Suspect Kia has the same problem. I own a 2018 Kia Sportage fe fwd w/ approx. 6500 miles.”

“Addendum to the complaint dated january through senator marco rubio office. I received a letter from NHTSA DOT that the investigation is open as to the software upgrade , should be labeled recall and into the theta engine , see attached. As I write this, my disabled husband is in a tow truck with the driver because he went to the dollar general store, turned the corner onto a busy highway and the car limp mode light came on, car shut down dangerously slow. Luckily he was not rear-ended. This is pathetic for Kia motors, Kia america to get away with this. These vehicles need to be bought back. …”
