I am submitting this report regarding an ongoing issue with my Kia vehicle related to the recall for code P1326 (Knock Sensor Detection System / Engine Bearing Wear). The first time this issue occurred, Kia documented the problem and kept my vehicle overnight to perform what they referred to as an “engine soak.” I was informed that this procedure might resolve the engine performance and oil consumption problems. I was also advised that if the issue reoccurred within 15 years of vehicle ownership or before reaching 150,000 miles, Kia would replace the engine under the recall warranty. Recently, the same issue has reappeared, but Kia is now refusing to replace the engine, citing “gaps in maintenance” from the early years of my ownership. I explained that, at that time, my father performed all oil changes and maintenance at home to reduce costs, as I was a young driver living with my parents. Kia is requesting proof of oil or tool purchases from over ten years ago, which I no longer possess. Additionally, all vehicle-related documentation was left inside the car when it was stolen and broken into twice—incidents connected to the nationwide Kia theft issue that has been subject to another class-action lawsuit. As a result, I no longer have access to those records. During my initial visit, the Kia service representative, Jake, assured me that if the engine failed again and I maintained the vehicle properly, I would be covered for a full engine replacement. I have made every effort to comply with those terms, yet Kia corporate has denied my claim. I am requesting the federal safety agency’s assistance in resolving this matter and ensuring that Kia honors its recall obligations and prior representations made to me as a consumer.

Kia soul engines are known for burning through oil very quickly. the recall does not include my car because i have a 2.0L engine. The excessive oil consumption of my engine completely melted the inside of my catalytic converter. my car only has 106,000 miles, so this shouldn't be an issue. I had my check engine light come on, so the mechanic told me to use different gas and turned the light off. My catalytic converter being completely blocked and melted is directly related to the oil consumption of the engine. i had two mechanics comfirm this. I experienced a major loss of power, and inability to accelerate normally, which can be very dangerous. I was trying to accelerate uphill on a road with little shoulder space or many places to turn around, and my car STOPPED and the check engine light started blinking. Very unsafe, if my car won't let me accelerate and i come to an unexpected dead stop, it could cause accidents. I can't believe my car isn't included in the recall, it has the same issues as the 1.6L engine. I now have to put out thousands to get my catalytic converter replaced, and with the engine burning oil, it'll ruin a new catalytic converter faster than normal.

Excessive oil consumption noted at around 40,000 miles. No visible smoke coming from tail pipe but burnt oil smell coming from underneath car in region of catalytic converter. Had engine visually inspected and had pressure test done by repair shop; no engine seal compromise present. Took vehicle to dealer to report and was told that warranty did not apply to this issue. Car eventually burning 2-3 quarts of oil every 800 miles. Traded car in at just over 99,000 miles due to oil consumption and concern about failure. Private party mechanic and oil change facilities very familiar with this issue on Kia souls. Noted that class action lawsuit against Kia for this very issue was initiated in California but was abruptly dropped. First vehicle I've ever owned that had to have oil added between changes. Noted that Kia owners manual stated that up to 3 quarts of oil consumption between 7500 mile oil changes is normal. I had oil change service done predominantly every 3000 miles.

My 2015 Kia Soul is experiencing ongoing, severe oil consumption. Despite having an extended warranty for rod bearing failure (15 years/150,000 miles), my Kia dealership refuses to perform an oil consumption test because my vehicle has slightly exceeded 100,000 miles (currently at ~106,500). I brought the vehicle in multiple times for oil loss before reaching 100,000 miles, but no one informed me that a test existed or was needed. The car burns through oil every 3,000 miles or less, sometimes with no oil showing on the dipstick before the next change. It often chugs or knocks, but no warning lights currently appear. I previously received engine codes P1326, P0011, and P0014, and I did receive the KSDS update. The dealership told me I must wait for the engine to fail to qualify for replacement. This is unsafe for me and other drivers. Kia Consumer Affairs has confirmed I’m under warranty, but no solution has been offered to prevent a dangerous breakdown. I am concerned that this is a widespread issue that is being ignored unless the vehicle fails completely. I’ve been instructed by Kia service staff to continue topping off oil to avoid engine damage. However, by doing so, I am also preventing the P1326 code from triggering—effectively disqualifying me from warranty help. I’m forced to choose between protecting my car or triggering a code to qualify for repair. This puts consumers at risk and creates an unfair barrier to accessing the warranty coverage Kia advertises.

The component that malfunctioned is the catalytic converter, which became clogged due to excessive oil consumption from the engine. The oil consumption likely resulted in oil entering the exhaust system and contaminating the catalyst, causing it to lose its efficiency. The dealer replaced the engine but failed to inspect and replace the catalytic converter, which was clogged due to oil consumption from the engine. Yes, the catalytic converter is available for inspection and can be physically examined by a mechanic or technician to confirm the issue. The clogging of the catalytic converter resulted in poor engine performance, to include reduced acceleration, high rough idling and risk of fire. This lead to dangerous driving conditions, the vehicle stalled and had trouble accelerating. The issue of a clogged catalytic converter due to oil consumption has been confirmed by dealer. They performed diagnostic tests and read the vehicle's diagnostic trouble codes (DTCs) that indicated problems with the catalytic converter. No, the dealer relayed that they did not inspect the catalytic converter. Yes, I noticed symptoms prior to the catalytic converter clogging. Check engine light coming on. Reduced engine performance, sluggish acceleration. These symptoms occurred the day the vehicle became incapacitated. Rough idling was happening over time, during winter months.

Incredibly high oil consumption. Spending so much money on keeping oil in it.

Description of Incident: The engine has experienced a failure that causes oil to blow back from the engine, covering components both under and outside of the engine cover. This has resulted in oil accumulating on the exhaust and other hot components, creating a significant fire hazard. Safety Risks: This malfunction poses a serious risk to my safety and the safety of others, as the oil leakage could lead to a fire while driving. Additionally, the vehicle stalls at various speeds, which increases the risk of accidents or harm to other drivers and pedestrians. There is also a strong smell of oil inside the car, potentially indicating harmful fumes entering the cabin. Inspection Availability: The component/system causing the issue is available for inspection upon request. Reproduction and Confirmation of the Problem: The issue has been reproduced and confirmed by two SAE-certified mechanics. Inspection by Others: The vehicle has been inspected by two SAE-certified mechanics but not yet by the manufacturer, police, or insurance representatives. Warning Signs Prior to Failure: Warning signs included consistently losing oil even after a fresh oil change, smoke from under the hood, a strong oil smell inside the cabin, and the car stalling during operation. These symptoms have been ongoing and progressively worsening, with the vehicle now stalling more frequently.

The car has consistently burned oil, and I’ve had several engine-related repairs: 09/2022: Camshaft replaced. The check engine light came on again, but I was told the camshaft was fine and that the car just needed an oil change. 04/2023: Check engine light came on, AutoZone diagnostic code P0011. 06/2023: Check engine light on again, AutoZone diagnostic code P0011. 09/2023: Check engine light on again AutoZone diagnostic code P0011. 06/2024: Check engine light came on AutoZone diagnostic code P0014. 07/2024: check engine light on-taken to Firestone Auto for an oil change 07/2024: check engine light on- car to Christian Brothers Automotive, where the camshaft and timing chain belt were replaced. Documented a knocking sound in the vehicle. 09/30/2024: Vehicle shook violently on the highway, sputtering as if the engine would fail. Check engine light came on after car began to shake. 10/2024: We Care Auto diagnosed the car. I was told the engine needs replacement due to misfires, low compression, and no oil in cylinders 2 and 3. Safford Kia Brown of Manassas recommended replacing the ignition coil, spark plugs, and conducting a fuel induction service, diagnostic, and synthetic oil change. Given the car’s engine history, I don’t believe this will resolve the root problem, and it’s likely the car will need more repairs soon. Driving under these conditions compromises my safety and the safety of others, increasing the likelihood of a life-threatening situation. Per Motor and Wheel and Fast Company, the December 2020 recall addressed engine issues and fire risks in Kia Souls from 2014-2016. Owners reported hearing knocking noises before their engines failed or caught fire while driving. Some saw smoke before safely stopping, highlighting the dangers of unnoticed warnings. CarMax's warranty acknowledges the issue and is willing to authorize repairs, so I would like to know why Kia will not honor this as well. I ask Kia to reconsider and investigate further.

I own a 2015 Kia Soul affected by recall SC200, which addresses engine compartment fires due to oil/fuel leaks and potential engine damage. My vehicle experienced engine halts at high speeds, and Peak Kia in Littleton, CO, discovered a leaking valve cover gasket and PCV valve. Despite these issues being relevant to the recall, Kia and the dealership refuse comprehensive testing or repairs under the recall. The dealership initially suggested engine replacement but later claimed only a Knock Sensor Detection System (KSDS) update and lockup test were required. They refuse to conduct oil analysis, leak-down tests, or endoscopic inspections to rule out systemic issues or internal engine damage. The vehicle has been with the dealership for five weeks. Kia's customer service, including a case manager named Courtney, promised to review the case but failed to follow up. The District Parts & Services manager, Jacob, instructed the dealership to close my request without further testing and refuses to open a validation case or respond to emails. Kia Customer Support has promised callbacks for three weeks but has not returned them. The dealership is attempting to charge for an inspection fee and repeat systemic repairs despite these being likely covered under the recall. They have not addressed relevant Technical Service Bulletins (TSBs) ENG222 and FUE053, which provide guidance for diagnosing and repairing oil consumption and leak issues. I believe Kia and the dealership are not complying with the full scope of the SC200 recall, which mandates comprehensive inspections and repairs for any oil leaks. They are using circular logic to avoid performing necessary tests and repairs, potentially putting my safety at risk and leaving me vulnerable to future engine failure. I request the federal safety agency's intervention to ensure Kia and the dealership comply with the recall requirements, perform all necessary testing and repairs, and address the potential systemic issues with my vehicle's engine.

The Kia experienced acceleration issues and would randomly turn off while driving. A mechanic inspected and recalibrate the knock sensor. Almost immediately the car began to use excessive amounts of oil, a quart a week average, had a knock and started having acceleration issues. The Kia dealership stated that severe engine scoring had occurred likely caused by the catalytic converter. The problems began and lead to engine failure within several weeks. From March to end of May
