“My vehicle broke down on my family 2 hours away. The suv started engine failure with the engine light coming on then the rpm's reved up to 4000 and started chugging. We stoped at the gas station shut the vehicle off and got it towed home to a local shop. I have the 2.4 engine and less then 130,000 miles on it and the shop said my piston is gone and my engine is bad.”Owner report · Engine · Feb 2026

“I purchased a 2018 Kia Sportage and ever since the last few years the paint is starting to come off of this vehicle. I do not go through any type of car wash. I washed it at home. It is getting worse and worse than certain spots, I do not want any monetary for this I would just appreciate getting what I should have, which is fresh paint that last. The paint in the front bumper underneath the hood area is all coming off and it's like white. Then on the roof of that vehicle, there's white spots of the clearcoat actually coming off the whole vehicle. If you look also at my hood of the vehicle, you can see spots as well.”Owner report · Structure · Oct 2025
“My Kia Sportage has developed a loud engine knocking noise, which I understand is a known issue with Kia engines. I am concerned that this indicates internal engine failure and could lead to sudden engine seizure while driving, creating a serious safety hazard. The dealership denied repair assistance due to lack of oil change records, but the issue appears consistent with widespread engine defects reported in similar vehicles. I am requesting investigation into this issue due to the safety risk it poses.”Owner report · Engine · Oct 2025
“I started my car and it started shaking violently, and would jolt back and forth, I would be on the highway and the speed would decrease rapidly and overheat slightly to pick up speed”Owner report · Engine · Sep 2025
“Passenger outside rear view mirror the paint is peeling. It's the original rear view mirror. Vehicle looks brand new except for that mirror.”Owner report · Unknown Or Other · Sep 2025
“My vehicle suffered from a catastrophic engine failure while driving on the highway. The vehicle stalled at highway speeds (55mph), during rush hour. Causing a near rear end collision. From this point on my vehicle was unable to reach speeds of 30 Mph. This failure is consistent with a defect in the Theta II engines that has been subject to recalls. The Theta II engine recall is under a soft recall. It is not known to the public unless it happens to the owners vehicle. This sudden stall at highway speeds jeopardized the safety of the driver (myself) and the people and vehicles behind the driver.”Owner report · Engine · Aug 2025
“Due to excessive oil consumption and blow thru to catalytic converter, and burning of oil in the converter clogged up my catalytic converter as seen in pics causing exhaust fumes to enter cabin and engine not run properly. Driver or passenger must open windows to get fresh air. I had to have converter replaced. There is still periodic fumes that enter cabin even with new converter because engine is still consuming excessive oil . This should be addressed to and rectified through KIA corporation. Thanks”Owner report · Engine · Jul 2025
“Excessive oil consumption and the engine is part of a "silent" recall. I would like my engine to be replaced before it blows up and causes serious injury or death. I do regular oil changes and I can't keep adding oil daily. If they knew about this issue why wasn't there a mass recall to get this fixed.”Owner report · Engine · Jul 2025
