Multiple times with 6 months my check engine light comes on but no code is detected. However, when tested it tells me to look out for code P0420. The issues I have encountered: - High RPM of 2,000 when vehicle is started - Check engine light with no code. Light comes and goes on it own - Car jolts and vibrates high while idling - Car eats oil like no tomorrow. Having to do an oil change every 3,000 miles
NHTSA complaint #11757104 — an unverified report by a vehicle owner.
I own a 2014 Kia Soul 2.0L GDI that consumes approximately one quart of engine oil every 1,500 miles. The engine oil became dangerously low between oil changes without any warning indicator. The vehicle has also experienced reduced engine performance, declining fuel economy, and previously displayed a P0420 catalytic converter efficiency fault code. Replacing the PCV valve did not improve the condition. An overnight piston soak temporarily reduced the oil consumption, but the problem returned, suggesting carbon-related engine deposits. Kia has acknowledged that catalytic converter damage can create a safety hazard in certain 2012–2016 Kia Soul models equipped with the 1.6L GDI engine, and the NHTSA has issued a recall thereof (see "SC176 – 2012-2016 MY KIA SOUL ENGINE CONTROL UNIT (ECU) LOGIC UPGRADE SAFETY RECALL CAMPAIGN"). My vehicle is equipped with the 2.0L GDI engine and exhibits similar catalyst- and oil-consumption-related symptoms, but Kia declined assistance because my VIN is not included in the campaign. I am submitting this complaint because excessive oil consumption can allow engine oil to become dangerously low without warning, increasing the risk of engine damage or loss of power while driving. I request that NHTSA evaluate whether similar conditions are occurring in 2014 Kia Soul 2.0L vehicles.
NHTSA complaint #11753054 — an unverified report by a vehicle owner.
The engine has structural manufacturer defect causing extreme internal engine oil consumption with zero external leaks, creating a severe risk of sudden oil starvation catastrophic mechanical engine failure. The severe oil consumption problem was confirmed by a certified national corporate service center (Firestone Auto Care). An intermittent P0420 catalytic converter warning is actively appearing on the dashboard, which is a documented consequence of internal engine oil burning. When attempting to get this mechanical defect diagnosed and repaired under the class-action parameters, manufacturer dealerships (Findlay Kia and Jim Marsh Kia) declined to schedule the mandatory manufacturer diagnostic testing, preventing a known vehicle defect from being resolved.

Engine control system is STILL faulty. The engine light will not go off, even after the so called recall Software fix and the brand new engine put in my car in 2025 among other MULTIPLE brand new parts and repairs to my car trying to resolve the engine issue, oil consumption and fuel/gas consumption at rapid and alarming rate, every time after I fill my gas tank.
NHTSA complaint #11746423 — an unverified report by a vehicle owner.
Vehicle is experiencing rod-knock and engine performance issues along with a P0420 code for the catalytic converter. After using a diagnostic tool to retrieve code, a recall was present for the existing code, that explained the exact symptoms my car is experiencing. I have had the car since 2021 and have not received any notification regarding a recall for the engine; it was only after I ran a diagnostic check where I found out there was a past recall for the engine and catalytic converter (SC176). I called KIA customer service, and they explained that the vehicle did not receive the recall, however they could still not uphold the recall work because the vehicle is outside the warranty for the recall (Vehicle Odometer reads 150088), approximately 90 miles over warranty. Only indicator light that illuminated was the check engine light. The recall says the vehicle could overheat and is at risk of a fire hazard. I was not notified of any engine recall for the vehicle since I have owned the vehicle, and I am worried that my daily commuter will present a fire risk.

Engine and engine components caught fire while driving. This put my husbands life at risk and could have caused harm to other drivers if he was driving on a busier road. Car fire could have completely engulfed the car and caused harm or even death. Fire department was called to assist with extinguishing the fire and to ensure that further danger did not persist.
NHTSA complaint #11743824 — an unverified report by a vehicle owner.
There was a recall-SC209A for a faulty piston ring. This vehicle “passed” prior to my purchase. I was unaware that my vehicle was part of the recall- when the VIN is entered in the NTSB website, no active recalls show. Starting in 10/24, the vehicle began having problems accelerating, and when I brought to my local mechanic it was found to be nearly empty on oil despite a recent oil change. I have since experienced continuing issues with low oil and oil consumption. The latest incident was in XXX on a trip to [XXX] . The car seized in the highway, and was brought to a local Kia dealer. They diagnosed a bad transmission, and it was replaced. Despite this, the car has continued to burn oil. I have brought the car to my local Kia in Schaumburg where it was purchased. It was today that I found out it was part of the recall. I asked for an oil consumption test, and I was told this would be at a $200 cost to me. I am worried for my families safety taking this car on the road- the oil light doesn’t come on when it is low. Kia hasn’t offered to retest the car, and I feel at significant risk continuing to drive it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11741488 — an unverified report by a vehicle owner.
The vehicle is burning oil. It creates residue in my engine which may make it dangerous to drive and ruin the catalytic converter, among other issues. I was first notified of this problem during my second oil change in 01/2026 at a Kwik Kar Lube & Tune, about 6 months after purchasing the vehicle in 06/2025. As of 05/2026, an oil warning lamp began to appear on the vehicle dashboard to notify me that the oil was low. I checked the oil stick, and there was burnt oil, albeit very little of it. I had gotten a full synthetic oil change, so it was not yet time to change my oil, but clearly this issue is causing premature oil loss.
NHTSA complaint #11740483 — an unverified report by a vehicle owner.
Weeks before the vehicle completely shut down, my car began stalling and shutting off in traffic without warning while driving. I was usually able to turn the vehicle off and restart it, and it would come back on temporarily. At red lights and stop signs, the vehicle would power down, stall, jerk forward, and then begin moving again when I pressed the accelerator. On 05/01/2026, while stopped at a red light on my way to get gas, I noticed the vehicle vibrating unusually. I made it to the gas station, filled up, and drove away. However, as I entered a heavily traveled highway, the vehicle began shaking uncontrollably and completely shut off in traffic. I was unable to restart the vehicle and had to have it towed, and later towed again to a Kia dealership/service center. The diagnostic codes identified were: * P0014:00 – Exhaust Camshaft Position Timing Over-Advanced/System Performance (Bank 1) * P0017:00 – Crankshaft Position/Camshaft Position Correlation (Bank 1 Sensor B – Exhaust) * P0303:00 – Cylinder 3 Misfire Detected I am extremely concerned because the vehicle is only about four years old, and I purchased it a little over a year ago. I have previously taken the vehicle to Kia for recalls, including recalls related to engine issues. Based on my research and the symptoms of my vehicle, I believe the recall involving the piston oil rings may be related to the camshaft and crankshaft issues now occurring. I am concerned this may represent an additional safety-related defect or recall issue that has not yet been fully recognized by Kia. I am submitting this complaint to bring awareness to this issue and request that a proper investigation be conducted before more drivers experience a dangerous failure in traffic. I would also like to request direct follow-up regarding my specific vehicle and this incident. Due to the seriousness of the failure and the safety risk of the vehicle shutting down in active traffic, I believe my vehicle should be reviewed as part o
NHTSA complaint #11736581 — an unverified report by a vehicle owner.
I am writing to report safety concerns regarding my 2018 Kia Soul Plus. I have been experiencing several engine issues, including knocking noises, hesitation during acceleration, excessive oil consumption, and an active check engine light. Recently, while driving with my daughter, the vehicle began shaking and the check engine light flashed three times. Although I strictly adhere to the recommended maintenance schedule, these issues persist. My mechanic identified code P0455, but a smoke test did not reveal a leak. Additionally, despite having a full tune-up in August [2025] at 105,636 miles, I am being told I require another tune-up due to engine misfires. I am concerned about the frequency of these repairs and the overall safety of the vehicle’s engine.
NHTSA complaint #11735537 — an unverified report by a vehicle owner.
I am reporting a safety concern related to NHTSA Recall 19V120 involving my Kia Soul. The recall identifies a defect related to catalytic converter overheating, which can lead to engine damage, stalling, and increased risk of fire. My vehicle is currently experiencing an illuminated check engine light and unsafe driving conditions. During service evaluation at Kia of Columbus, I was informed that my vehicle has a catalytic converter blockage contributing to these issues. However, I was also told that my vehicle does not qualify for recall repair because no engine code was detected during diagnostics. This is concerning, as the vehicle is actively exhibiting symptoms consistent with the recall condition, including a confirmed catalytic converter issue and an illuminated malfunction indicator lamp. Despite this, I was denied full recall coverage and instead offered a goodwill repair requiring me to pay 50% of the cost. I believe this situation represents a failure to properly apply recall criteria and raises concerns regarding customer safety, as the vehicle may be at risk for engine failure or fire. I am requesting further review of this matter and investigation into the handling of this recall by the servicing dealership.

What component or system failed or malfunctioned? The engine (piston rings) and catalytic converter failed. The catalytic converter is available for inspection upon request. How was safety put at risk? The engine ran low on oil without any external leak, causing warning lights and engine rattling. Low oil pressure can lead to sudden engine seizure or fire. The failed catalytic converter can clog, causing loss of power on highways and increasing the risk of a crash. Has the problem been confirmed by a dealer or independent shop? Yes. A Kia dealer found the engine 2 quarts low, with no external leak, and recommended replacing the catalytic converter at a cost of over $6,000. An independent mechanic confirmed code P0420, which indicates catalytic converter failure. Has the vehicle been inspected by the manufacturer? The vehicle was inspected by an authorized Kia dealer, but they did not complete the required inspection for Recall SC336 (defective piston oil rings). They did add the software. Were there warning lamps or other symptoms? Yes. The oil pressure warning light and other dashboard lights came on. The engine made a rattling noise. The vehicle later felt sluggish on acceleration, fuel economy dropped, and the exhaust developed a smell. The check engine light came on and later turned off, but code P0420 was stored in the system.

While driving under normal conditions, the check engine light began flashing and the vehicle suddenly lost power and entered limp mode. Acceleration was severely limited, making it difficult to maintain speed in traffic. The vehicle was later diagnosed with diagnostic trouble code P1326, which is associated with engine rod bearing failure. This caused an unexpected loss of engine power and created a safety risk while driving. The vehicle had to be taken to a dealership for inspection due to the severity of the power loss.

No accident occurred but a close call. The vehicle made it about another 1 mile before stalling again this time losing all control in steering as well and was towed home.
NHTSA complaint #11716039 — an unverified report by a vehicle owner.
I’ve had nothing but problems with this car since about a year after getting it in 2021. Constant noises with the engine engine check light coming on all the time I would bring it in and no one would be able to figure out what was going on. And then it started to get worse and I had my catalytic converter replaced and not even a couple months later I had to have had another catalytic converter put in there’s issues with oil consumption and between oil changes, I would have to top off my oil multiple times sometimes even five and then I started getting oil changes before I even needed to get them because I was nervous and then on January 22, 2026 driving on the highway my engine started to smoke and I pulled over and took it to the nearest dealership by way of tow truck and they told me that the fuel issues had destroyed my second cylinder in my engine, and it was not repairable and then told me that I needed to replace my engine, but the engine in my car is no longer being made. I was told that my car was running lean due to the fuel injector issues.
NHTSA complaint #11713366 — an unverified report by a vehicle owner.
While driving on a road trip from Charleston, South Carolina to Florida in January of 2023 the factory installed catalytic converter failed (front facing) clogging the exhaust system and damaging the engine (engine now experiences blow by and pistons rings have been damaged). A recall for the overheating of the catalytic converter was marked as repaired before I bought the car. However, I believe that either the update was not done to the on-board computer or that a damaged catalytic converter was not replaced. This directly led to the subsequent failure in question and has since damaged my engine. At the time of the incident, an investigation of both catalytic converters revealed heavy sediment deposits and the core of the filtering component of the front facing unit had become so corroded that a chunck of it had broken loose and become lodged in the connecting hose that linked it to the rest of the exhaust system, leaving the entire system blocked. Because I bought the car used, I wasn't aware of the recall history at the time of purchase. Nor was I given a vehicle history report or receipts for any work that had previously been done. When I pulled a vehicle history report shortly after the incident I was unable to accertain what the actual repairs to the car were previous to my ownership, just that it had been taken to a Kia dealership for service with dates listed. The issues still remain and I am unable to afford the lengthy and very expensive repairs suggested by multiple mechanics to correct them. I also still owe money on the note as the result of having to deal with a predatory business to secure financing in the first place. I hate to think I was taken advantage of but I can't help but feel like the catalytic converter should have been changed during that previously marked recall repair and clearly wasn't. Please help me figure out what went wrong here and if possible help me remedy this situation, especially if there was indeed fraud involved. Thank you
