2019 KIA OPTIMA Complaints

Car was affected by emergency theft system locked car down when moving and caused airbags to deploy in which fractured my spine vertebra causing spinal fusion

Brought vehicle in for Recall-SC340 Theta II 2.4L GDI ECM S/W Upgrade. After service was performed I took my vehicle back home and noticed that my down shifting was different, jolty and clunky. Prior to the upgrade my vehicle shifted flawlessly. Took my vehicle back in to have them check it out and they told me that they couldn't feel it and that the upgrade wouldn't cause that. Called Kia Corporate and filed a complaint.

The contact owns a 2019 Kia Optima. The contact stated that the catalytic converter was previously replaced. The contact stated that while driving at 60 MPH, two weeks later, the check engine warning light illuminated, and the vehicle started misfiring. The contact drove to the residence. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine needed to be replaced. The mechanic related the failure to an unknown engine recall, and the contact was referred to the dealer for assistance. The vehicle was taken to the nearby dealer, where it was diagnosed with engine damage. The dealer acknowledged the unknown engine recall, but the engine was not replaced. The manufacturer was notified of the failure and informed the contact that the part of the engine that was damaged was not covered. The vehicle was not repaired. The failure mileage was approximately 179,000.

I purchased a used 2019 Kia Optima from a dealership in January 2025 with 103,000 miles. 11 months later it's burning oil. Every 2 weeks I have to add a quart of oil. I took it to my mechanic and they found cylinder 4 has been burning oil. They also found a technical service bulletin related to engine oil consumption. They recommended replacing long block assembly. They referred me to a Kia dealership. Currently, my vehicle is at a Kia dealership. They performed a "leak down test" and found cylinder 4 has been burning oil and recommend a long block assembly. I have a 3rd party warranty on my car. They are currently reviewing this claim. If they decide to replace the long block assembly, there will be additional uncovered costs that I feel Kia should be responsible for. I have only put 7,000 miles on this car since I bought it 11 months ago. The car currently has 110,500 miles on it. I understand this is a used vehicle but engines should last 200,000+ miles. I'm trying to figure out my rights. By law isn't the dealership responsible for this oil consumption loss and long block assembly replacement?

Unknown needing help with new purchased car. Bought this car October/2025 with 93k on engine. Already been to dealership i Bought it from to have current issues im dealing with checked out and they only listen to it and said it was injector ticking clatter. Since then ive seen white smoke and the car burning excessive oil. I am adding oil to the car every 2-3 days. Still noticeable smoke and smell of burning oil. No recall on this vin. It seems as if this is a huge problem with this engine. Please help

Engine burners oil at about 1qt per 1000 miles. There is no leak, and no repair to stop the oil from burning quickly. I have to refill my engine with oil several times in between oil changes. Paint is peeling in various spots on my hood and bumper. I first noticed a small area along the border of the hood nearest the windshield (mostly visible from the driers seat). Then 3 more spots on the opposite side of the hood and eventually all over the bumper.

After routine maintenance replacing the valve cover gasket, the low pressure GDI fuel line developed a leak in an area away from where the maintenance had occurred. After a 10 minute drive, the car developed a fire in the engine compartment. Upon investigation by an independent auto mechanic, it was determined that the fuel line had become brittle and developed a crack that had sprayed fuel into the hot surfaces of the engine compartment. This appears similar to the scenario affecting earlier Kia Optima models with the 2.0L Turbo engines. The heat from the fire caused the brakes to start to fail and the amber check engine light to come on within about 5 seconds before smoke was observed coming from the engine compartment. Fortunately, the fire occurred as the vehicle was pulling into the owner's driveway and a fire extinguisher was nearby and used to put out the fire. The vehicle's occupants were able to exit the vehicle with no injuries.

My vehicle is consuming oil excessively. I have to put a whole quart of oil in my vehicle every 2 weeks. I am adamant about getting regular maintenance oil changes as well. My car had to be towed to a local auto shop due to the engine stalling and accelerator not working. They had to replace all 4 coil packs and 4 spark plugs due to dark, tarry oil covering the parts. The repairman told me my engine was at risk of failing, and that the repairs he did would not last without a new engine. I am worried about the car stalling or failing while driving, which puts an accident occurring at greater risk. My complaints resemble symptoms tied to previous Hyundai/Kia engine recalls. I am requesting investigation and manufacturer action related to this issue.

The motor burn oil even after the oil change is done. Also, the car shaking and is not damage to be found.

Red oil light came on along with check engine light took to shop got oil change and they test pressure all is good but oil light and engine light still on replaced oil pressure sensor switch and variable valve solenoid lights still on took to kia dealership they said say thing as first shop replaced oil pressure sensor switch again because they said the aftermarket one doesn't work on my car so bought part from dealer changed it light still on.
