“For the past 6 months or so, I've been experiencing an unknown issue. I'll be driving along, steadily and all of a sudden my engine and RPM gauge will rev up and then go back to normal. My speed doesn't change, no lights go on, just the rev-ing sound and the gauge goes up. It's very alarming to me. I've checked with Kia and they're aware of the issue but state that there is currently no recall or alert as to what exactly the problem is or how to solve it.”
NHTSA complaint #11190511, filed 2019-03, 35,000 miles“Initially, I attempted to crank the vehicle by pressing the starter button. I heard a click and noticed quick flashing lights from the dash, then nothing happened except clicks, noises and minimal light as if the battery was down. There was nothing on inside the car to cause battery failure. The brake was hard to press down to restart the vehicle. Therefore, I opted to jump-start the car and it immediately powered up. All of the lights on the dashboard flashed on a few times then the letters afls appeared on the dashboard. …”
NHTSA complaint #11416596, filed 2021-05, 39,500 miles“I bought this car in may of 2020 with 44k on the odometer. Three days later I was on a 3400 mile road trip on the highway when I started hearing knocking from the engine bay. I took it in and had them listen. They told me it was completely normal. The knock went away for about 400 miles then came back. I took it in to 4 different dealerships. I got told there had been a recall on the motor but that it had been fixed already. The day after I got home the car died at 30 MPH on the way home from work and left me in the middle of a very busy intersection almost causing me to get hit. …”
NHTSA complaint #11372948, filed 2020-11, 44,000 miles“I was riding on the highway at about 65 mph and then the check engine light came on, the car slowed down and lost power. Now when I take off I have to barely mash the gas to pick up speed, if I mash the gas pedal hard it barely moves and it loses speed and power going up a hill. I took the car to two different part store and had a reader hooked up and it said the power powertrain control module needs a reprogramming.”
