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

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 federal safety agency 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 the federal safety agency evaluate whether similar conditions are occurring in 2014 Kia Soul 2.0L vehicles.

The contact’s wife owns a 2014 Kia Soul. The contact stated that on several occasions after refueling the vehicle, there was an abnormally strong gasoline odor inside the cabin of the vehicle and outside around the vehicle. The contact stated that while the vehicle was parked on several occasions, there was condensation under the gas tank. The vehicle was inspected, and there was corrosion underneath the vehicle on the gas tank, and the rear of the gas tank was separating. The replacement gas tank was purchased but the refurbished gas tank had the same corrosion on the gas tank. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 140,000.

In June 2024, my 2014 Kia Soul (VIN: [XXX] ) experienced a sudden engine failure without warning. I was driving on a busy road when the engine began sputtering and quickly stalled. The vehicle became inoperable and had to be towed. I had it inspected at a Kia dealership, who diagnosed the issue as complete engine failure but have not provided me with a full diagnostic report despite multiple requests. This type of failure is consistent with the known defects in the Theta II engine that have triggered recalls and extended warranties in similar Kia models. Although Kia has denied coverage for my vehicle, I believe this is a related safety issue. The vehicle stalled unexpectedly, creating a hazardous condition on the road. I was traveling with my toddler in the back seat and felt our safety was at risk. I am submitting this complaint because I believe this failure is not an isolated incident and should be investigated. Kia has refused to acknowledge a defect, but the symptoms match those in previous recalls for other Soul and Forte models with similar engines. I have also attached documentation showing service history and repair costs, and I am happy to make the vehicle available for inspection.

Ive tried to get my recalls fixed since I bought the car 2 years ago, Jeff Wyler Kia Eastgate Ohio has given me the run around, at least 5 attempts of no call backs or prolonged appointment dates not having me on record, my car breaks down I pay for diagnostic blown engine, I pay to have it towed to Jeff Wyler Kia Eastgate Ohio, it's been there for 5 weeks and they still have not done a diagnostic on it. They are saying they never received my driver's license, then it was proof of ownership, they won't call me back or email. I'm just so frustrated because Kia the main company actually has sent me many letters to get it fixed I call them and they told me their wasn't even a diagnostic done, they tried reaching out to them. Should I tow my car to a different dealer? I'm not sure what to do anymore, I'm almost afraid now they'll say they can't cover it for same reason, my trust is gone at this point with the dealership. I recently had a full knee replacement and getting in and out of my daughter's car has been very hard on me, I asked for a loaner and they said they don't provide them there and I have to pay. I've already put in so much money on this car at this point I feel cheated or targeted for some reason. They treat me like I'm trying to get something for free, they aren't paying out of their pocket. My car is still sitting there soon to be 6 weeks and don't know what to do, the treatment of this dealership is beyond horrible and I don't trust them. it's not my fault this happened I'm sorry for everyone involved especially Kia , it must be a lot, Thank you for listening to me , I hope you have a great day [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle Information: 2014 Kia Soul (Base Model) VIN: [XXX] Approx. Mileage at Failure:91,000 Incident Date: [XXX] Complaint: On [XXX], the catalytic converter in my 2014 Kia Soul failed. This follows the completion of recall SC176 on July 14, 2022, which addressed excessive exhaust gas temperatures caused by abnormal combustion conditions. While Kia representatives have claimed that SC176 is unrelated to the catalytic converter, it’s well understood that excessive exhaust heat can lead to long-term thermal damage to emissions components—particularly the catalytic converter. One representative even appeared concerned about the implications of SC176 during a phone call, before quickly changing direction. I believe this catalytic converter failure is a delayed consequence of the issue SC176 was meant to address, especially since the converter is part of the affected exhaust system. This failure not only poses a financial burden—since it falls outside the federal emissions warranty—but may also reflect a broader issue that other 2014 Soul owners could face. The component failed resulting in immediate loss of power on a US interstate highway. I’m requesting the federal safety agency investigate whether catalytic converter failures like mine are in fact related to the defect addressed in SC176 and whether Kia should be required to offer further coverage or corrective action. Additional Information: I can provide documentation upon request, including: •Receipts showing consistent oil changes and routine maintenance •Service records for all recall work performed on the vehicle, including SC176 (completed on 7/14/22) •A repair invoice for the catalytic converter failure (currently pending — my vehicle is still at the service department as of today, 4/16/25) •A timeline of communications with Kia Customer Care Please let me know if any of these are needed to support further investigation. I’ll gladly provide them once available INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving and my MIL came on. When I parked, I could smell strong exhaust fumes. I went to get an OBD2 scan and it came back with P0420: Catalyst System Efficiency below Threshold (Bank 1) reading. I was told to replace the O2 sensor. After getting it replaced, this did not fix the issue. After some research, I discovered there is a TSB out recommending CATALYTIC CONVERTER inspection and/or replacement. However, it only applies to the 1.6L engine and not the 2.0L engine, which makes no sense. The dealership denied coverage because of this and the vehicle exhaust fumes are still strong. This can cause emissions issues later, so the TSB should be expanded to all Kia Soul models, regardless of engine size.

My 2014 Kia Soul ! has had 2 codes, P1326 which is related to a Knock Sensor Detection System (KSDS) which has ties to a known Rod Bearing issue. And a P0420 code related to the Catalytic converter. There was a lawsuit which led to a Recall issued for this vehicle, however, it appears only for 1.6L engine. Mine is 2.0. Just basic online searches have discovered an overwhelming amount of other owners of 2.0 also getting the same issues with there's as well.
