“If I slow down then speed up it takes off slow. If I go up a hill it putts and when I drive it just feels like its puttering the whole time. Took it to dealership of course they didn't find anything but this is a new car I know something is wrong. I just got the car in march drove fine no accidents or anything and it's kind of disappointing that my car is like this but know one knows what's wrong.”
NHTSA complaint #11290177, filed 2019-12, 9,200 miles“I was driving up a hill and as I reached the top of the incline, my car stopped accelerating. I then attempted to use my brakes and I barely tapped them, but they reacted as if I slammed on my breaks. I took my foot off of the brakes and I began rolling backwards even though my car was still in drive. My brakes were then locked, I put my car in park and then turned off & then back on my car without removing the key. I then put my car back into drive, however, my gas pedal was still not working. …”

NHTSA complaint #11311882, filed 2020-02, 8,801 miles“Since I have had the vehicle I have had to have multiple Spark Plugs and Engine Coils replaced, literally every 4-6 months. One diagnosis said there was a problem with the motor, when I told Kia, they did not come back with the same diagnosis, well they sort of did, but did not noter it as an issue. Also, my car burns oil way too fast. I'm having to put in 2-23 quarts every 2-3 weeks. I have been told that the GDI motors are the culprit for this. …”
NHTSA complaint #11550425, filed 2023-10“I am reporting a recurring safety hazard involving my 2019 Kia Optima following a repair for diagnostic code P064A (Fuel Pump Control Module). Despite the dealership attempting to repair the fuel system, the vehicle remains in a 'limp mode' state. While driving, the vehicle began shaking violently and lost significant power, refusing to accelerate above 50 mph. This creates an immediate safety risk, as the vehicle cannot maintain highway speeds or safely merge, increasing the danger of a rear-end collision. …”
