The car engine is losing oil without any leaks being found. I got my oil changed and was told to have it done every 3k miles. Within a month of that oil change, my engine ran hot. I had all of my components checked. Radiator and coolant was fine but they found that my engine was 2 qrts short of what should be in there. I told them that the oil was just changed not even a month ago and that had to be false unless they weren't fully giving me the quarts that I paid for. They stated that this particular engine burns oil for unknown reasons as no cracks or leaks are ever found and to alleviate the issue, I would need to come in and pay for addtl qrts to be added. This is crazy and costly to owners! Kia knew that their engine doesn't perform as it should and can give way to cars overheating and potentially causing an engine fire. This should be a recall to replace the engines so that they perform as they should. This was deceitful practices that Kia set in play.

2018 Kia Sportage (78,051 miles). Vehicle is part of the Kia Engine Class Action Settlement due to severe internal engine defects. The engine suffers from catastrophic oil consumption, running almost completely dry three times in less than six months with no external leaks, meaning it is internally burning motor oil at a dangerous rate.This known engine defect caused severe consequential damage to the exhaust and emissions systems. On Aug 12, 2026, a Kia dealer technician diagnosed active code P0420. The technician's video inspection stated both the catalytic converter and O2 sensors are completely "out of specification." This double failure is a direct result of the engine defect blowing excessive liquid motor oil out of the engine block and down the exhaust pipe, fouling the sensors and melting the internal catalyst.This failure happened immediately after receiving the mandatory Kia Recall SC340 update (Catalyst Overheating Protection). The vehicle is under the 80,000-mile Federal Emissions threshold, but Kia is denying coverage based strictly on a calendar time limit. They refuse to take responsibility for emissions components destroyed by their settlement-recognized engine defect.This condition poses a serious safety hazard. Driving with heavily fouled O2 sensors and a failing catalytic converter causes poor engine performance, unpredictable stalling or hesitation during acceleration, and excessive unburned fuel vapors to enter the environment and potentially the cabin. I request the federal safety agency investigate Kia’s refusal to cover secondary emissions damages directly triggered by their defective oil-burning engines.

My 2020 Kia sportage spontaneously caught fire. It started smoking about 1/3 mile from my destination. There were no dash lights on and the temperature gauge was not elevated and was below half so it wasn’t the engine overheating. I pulled into the parking lot and shut off the car and the smoke then increased and turned darker rapidly and the car caught fire and was quickly engulfed and then there were several explosions. The car was a complete loss. Had I taken any more time to figure out the smoke I would have been a casualty.

On Feb. 1, 2026 my 2022 Kia Sportage caught fire while parked and turned off. The vehicle had been stationary and was not running at the time the fire started. There were no warning lights, no prior overheating, and no collision or external cause. The fire appears to have originated from the engine/electrical area. This incident resulted in a total loss of the vehicle and posed a serious safety risk, as the fire occurred without warning. The vehicle was properly maintained and had no known modifications. This incident is concerning due to previous reports of Kia vehicles experiencing spontaneous fires related to electrical or engine components. I am requesting this incident be investigated for potential defects in electrical systems or engine components that may cause fires while the vehicle is parked and turned off.

Battery died, fob didnt work 2 times had to hv towed, right front light seems as it has a short, overheated out of nowhere, now all headlights and backlight including brake light no longer work. Very unsafe and unable to drive. Everything in the recall has happened except for catching on fire. The tow hitch, I dont have one so it wasnt completed in the recall. This is unsafe and very dangerous. Per nhsta which I have filed complaint advised that this has nothing to do with my warranty.

I need help and agent advise nothing can be done bc the recall has been repaired, but it was a fail and now I hv to take the hit for it.
