Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“At 148,000 miles on the freeway the gas pedal would not give any power, still running but would not go, stalled a few times. Had to pull over and wait, restart and go a few miles, pull over and wait, then go, etc. Come to find out there was not a drop of oil left. After replenishing, still had issues, then noticed the anti-freeze was low. Replenished is now drivable but continues to burn oil. No leaking & I changed the pcv valve with no results. I'm still adding close to a quart of oil everyday. …”

NHTSA complaint #11328270, filed 2020-06, 148,000 miles

“The issue has occurred four times since purchasing the car at the end of december 2017 (less than 6 months ago). The dashboard will light up with a number of icons after the car is turned on (see photo from december). The first time this happened, it was a bitterly cold day and the icons popped up as I was driving. I felt the steering become tight, but luckily I was turning into a parking lot to safety. The icons went away after running the car for a long time (I was told it was just the cold weather). But when I checked on my car later before driving, the icons returned. …”

“The car would constantly stall, would need to jiggle ignition to get car to turn over. burn oil EXTREMELY. would foul spark plugs around 20k-30kmiles. , coolant would get burned and get shot out to the exhaust area, and finally the car would have smoke coming out of the engine bay after driving for a distance of 15-30 miles while also getting terrible MPG. Car on average should get 38mpg highway and 27mpg city. This car was getting about 20-22mpg highway and 16-20mpg city.”

“I took my car in and kia is stating that my upper catalytic converter manifold is bad. That should not be happening under 100,000 miles. Of course kia would cover it if it was under 80,000 miles. That's not the case with my car and of course my car had a little over 80,000 miles. So that comes out of pocket when it should not be happening.”

NHTSA complaint #11555834, filed 2023-11

“My car is experiencing excessive oil consumption. Upon inspection, it was determined that the issue lies with my catalytic converter. I have discovered that this problem has been reported in other Kia vehicles. The information I found suggests that the oil I am using is being bypassed by the catalytic converter, which indicates a potential issue with the Kia car’s design. Engine light won’t go off”
