2014 Kia Soul Fuel system Problems

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.

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 NHTSA 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.

Please see the attached statement for a more detailed explanation. To summarize, Kia will not perform a recall to repair the knock sensor in my 2014 Kia Soul. The reason provided was that my engine needs to be replaced first. However, this recall calls for engine replacement if Kia is unable to perform the repair. The issues I am having with my engine are symptoms of a faulty knock sensor, which is the recall Kia will not repair.

This vehicle was parked prior to the incident. The 2014 Kia Soul had been backed into parking space number 28 and pulled forward midway through the space where it appears the car was put back into park. It was here the occupant of the vehicle, Mr. Keith Nash perished in a fire that consumed his 2014 Kia Soul while taking his life. The 2014 Kia Soul has an open NHTSA recall 20V-750 and would have been eligible for settlement in the Kia Engine Class Action Settlement. [XXX] (C.D. Cal.) (https://kiaengineclasssettlement.com/CheckVIN). A copy of the Sharonville Police Report, [XXX] is attached along with the Sharonville Fire Department Incident type: [XXX] to this vehicle complaint. These reports go into great detail of this event. Based on this manufacture, and their parent company Hyundai’s history of non-collision fires and the hundreds of prior complaints on file with NHTSA, one might speculate that while in motion Mr. Nash noticed smoke from under the dash and put the car back into park. An engine fire can go from nothing to fully engulfing a vehicle in seconds, and as documented with these vehicles rendering the electronic door lock inoperable (as noted in the [XXX] incident in the rented 2019 Kia Soul). In a panic he placed his foot on the accelerator causing the motor to rev to a high RPM. It was noted in the report he seemed distorted and unable to escape, this is to be expected. This 2014 Kia Soul would have been one of the 13,114,339 vehicles recalled for non-collision engine fire according to the Center for Auto Safety Hyundai/Kia Fire and Engine Recalls 2010-2024 report, updated on March 28, 2024. Kia was aware of this incident as well as the owner’s insurance carrier Allstate insurance, yet they both failed to fie a complaint with NHTSA. This behavior is inexcusable and jeopardizes the safety of every American on the road and in close proximity to these manufactures’ vehicles.

Incident

The engine is consuming motor oil in excess after conducting oil changes. If it goes unaddressed after oil changes, it causes the pins in the engine to not operate properly. This results in a check engine light requiring the owners to get another oil change prior to actually needing one. Kia motors is aware of this issue; however are only willing to replace the engine if it fails due to pins and not the excessive oil consumption if your mileage is over the 10 year/100,000 miles. Both issues are interrelated and the engine needs to be replaced regardless!

I drove my car a short distance, parked, and turned off the engine. about 5 minutes after I left my car in the parking lot, we heard a loud explosion and everyone in the office stepped outside. My car became a ball of orange fire and burned for some time. It took 3 fire trucks to contain the fire and several other vehicles were damaged from the explosion. Pictures taken after the incident show the engine was gone (melted maybe). The inside of the car was also burned beyond recognition. My potential death was approximately 5 minutes after I parked my car. The gas tank did not explode; rather, the car burned from the front to the rear. This vehicle should not be on the road and the problem should be made public immediately.

I was driving the speed limit of 60 mph and all of a sudden it sputtered and hesitated; stalling out while attempting to accelerate going lower speed. My vehicle luckily got a parking spot at an automotive repair shop. No warning signal illuminated during my driving incident. The next morning the engine wouldn't start, but eventually they get it to start. They got the "Check Engine Message Center Warning" showing during Road Test. The automotive repair shop did a diagnostic test on it saying that the technician diagnosed the problems to a bad fuel injector fouling out the spark plug #4 cylinder recommending to replace all 4 fuel injectors and spark plugs, my transmission has no dipstick, OE Factory Maintenance due and is required, tires were getting weather cracked and recommending tires soon, technician noted that the car had some oil leaks and needed to be diagnosed further, cabin air filter missing and need to install a new filter; recommend cabin filter replacement service: includes anti-bacterial duct service, Tune Up Items: Fuel induction service recommending tune up labor 3-part fuel induction system service to where tune up is due/overdue by mileage if not already done so, Engine Oil was Over Filled Dark/Contaminated with Fuel in Oil and recommended oil change after changing Fuel Injectors and Plugs (BUT, I had my oil changed about a week before all of this occurred), Air Filter: OE Maintenance Interval Dirty and recommended installing new engine air filter, Brake Fluid: OEM recommended service interval/Brake Fluid Exchange service recommended due by mileage if not already done so. I purchased this vehicle December 10, 2022 and then this all occurred after just 4 month of purchasing this vehicle. It took 3 weeks to fix this vehicle. I had this fixed and still I have to wonder how safe is it really? I'm concerned so much so that I plan on taking this vehicle to a Kia Dealership appointment tomorrow June 17, 2023 to have a Multi-Point Inspection.

My check engine light came on and took it to Coastal Kia. Was told the catalytic converter needed to be replaced. After checking it’s not on the recall list but why are some on recall and not others. It started with the light at 127,000 miles. At first it would only stay on for a few days and then go off. Now it stays on all the time. I’m going to have it replaced but trying to find out why only some of the 2014 Souls are under recall

Since I bought this car, I have experienced hesitation, stalling, high RPM idle, fluctuating idle, burning smell, lurching, running though gas very fast (not due to increased driving), engine noises, dash panel half lighting up, hard to accelerate when the headlights are on, or heat, or air con, odd noises..and through this entire time, check engine light comes on and off and on and off...along with my gas gauge saying empty when its full. I have reported ALL of this throughout the entire time since all bought it. Every single time they say "software update" and send me home with nothing ever fixed. EVER. Now again check engine and false fuel reading, hesitations, etc....again! This engine and fuel pump is bad and explains all of my complaints since 10kmiles. My car has under 80k mi on it, its been a lemon from the start. Hesitation with no pick-up at an intersection and noises....just beyond dangerous. I have not driven my car on the freeway in 5 years because itis not safe, but Kia NEVER checks out problems. They charge for inspection and say "software update". Its maddening.

check engine light came on the evening of 3/08/2023. Auto zone said it was a knock sensor code and was listed as a recall. Next morning while driving on highway to ft Wayne Kia dealership my car engine lost rpm while driving at 65 mph on i-69 chapel exit in ft Wayne indiana. The car engine compartment almost immediately ignited into flames with an explosion. Driver barely got out before fire was in the dash. The front interior dash and front seat areas were caught on fire. Shrapnel blown from car started a grass fire as well. The fire department arrived to get both fires under control. My car was still under warranty at 108 months and 89,000 miles. Never had any problem with my Soul until that next day after light came on. I was not notified of the recalls except only recently received an airbag recall on 3/30/2023. I have contacted Kia to file a claim with them.

While driving on the highway, my car blew a puff of smoke, and I was no longer able to accelerate higher than 15 mph. I had to stop and get my vehicle towed to the local Kia Dealership because my vehicle was inoperable. The dealership told me that DTC P0420 was triggered and that I would need a catalytic converter replacement, exhaust flex pipe replacement, and a new drive belt. There is a recall (NHTSA Campaign Number: 19V120000) for the exact issue I experienced and my vehicle falls in the category of MY2012-MY2016 Kia Soul with a 1.6 liter engine, but the dealership is stating that my vehicle is not part of the recall population and it will cost $3,000 to fix this known issue. This is unacceptable and the recall population needs to be expanded.

A loud bang was heard while driving approx. 35 MPH on a clear day. The vehicle lost all power, smoke started coming from the hood area and the cabin began to fill with smoke. Driver pulled over, opened the hood and discovered the entire engine compartment in was engulfed in flames. Passersby tried to extinguish the flame with fire extinguishers, but it kept reigniting. The fire department arrived and put out the flames. This could have been life threatening if the driver did not get out of the vehicle. Amica Insurance's claims processors and an independent forensic investigator engaged by Amica Insurance have concluded the engine fire was the result of catastrophic engine failure. The forensic investigator noticed an outward bump in the oil pan and indicated this was likely the result of a separation of crankshaft and or piston rod elements. The investigator indicated he sees about 10 of these engine fires each month. Kia's special unit that addresses their engine fire problem has been notified and are dragging their feet. We have not heard anything from them after filing a claim on or about 3/22/2022. There were no warning signs prior to this catastrophic failure event. Gauges and warning systems were all normal. The engine and the engine compartment are a complete loss. Other damage occurred as the fire department worked to extinguish the fire. The forensic investigator and Amica's claims processor have declared the car a total loss.

I am unaware of what is able to be inspected of the vehicle at this time due to the amount of damage. My own and other drivers’ safety was at risk when my car began smoking and eventually caught fire. Nothing has been reproduced, inspected, or confirmed by any manufacturer, dealer, or independent contractor. I had my car in park for 2 hours before I began my trip. When I started the car up in the parking lot, the engine ran for about 10 minutes before I left. Within 2 miles of driving, the check engine light came on and the engine started smoking. I pulled the car over as soon as I could do so safely, put the car in park, turned off the ignition, and evacuated the vehicle. Soon after, the car ignited into flames under the hood and I called 911. The fire department extinguished the fire and reported to me that it was an electrical fire.

Incident

Feb 18, 2022

While driving at 15-20 mph, the engine started knocking loudly, smoked a little and died. There were NO warning lights or messages. There were NO previous symptoms, the car had been running fine and the oil and water had been checked 3 days prior. My car had never leaked or burned oil. I was able to restart it, the knocking was very loud. I was a couple miles from home so I slowly drove it home stopping 3-4 times to allow it to cool. At home I checked the oil and all had drained out except what was still dripping out underneath. A mechanic friend added oil and started it, it still knocked loudly and he thought a rod and/or rod bearing were bad. I parked it not knowing what to do yet. A little over 2 months later I was notified of recall 20V750, SC200. This was during covid. Between end of Jan 2021 (when notified) and Nov 2021, I had been quarantined 4 times and had lost my job so I couldn't afford to tow to the dealer. When I did, Nov 22,21 the dealer would not honor the recall because an update on the KSDS on the ECU was not done. The recall letter said they would do the update and repairs. I researched all letters from Kia to their dealers, other owners and NHTSA. THERE ARE NO RESTRICTIONS or conditions regarding this. ALL information states the update will be done with recall repairs, there is no time limit given (other than an offer to recieve a free Visa with update that expired 11-15-21), and suggests to do it asap. Even letters to dealer had 2 Q&A letters, each had a question if there were any restrictions on owners, the answer is no on both letters. There are NO restrictions regarding the updated ECU, the warrenty, or condition of the car. Kia DOES give the dealers instructions for cars that are towed in, if stored, if they start, if they crank. Each of these INCLUDE updating the KSDS, again making the excuse I was given false. There was NO reason the update could not be done and my car repaired PER KIA'S instructions to dealers and recall owners.

The front of the car started to smoke (black smoke coming from under the hood) while driving on a highway and caught fire within one minute. The safety of the driver was at risk. He barely had enough time to get out of the car before the whole front of the car burst into flames. The driver had to call 911. The FDNY put the fire out with NYPD present. The fire was so big that there was nothing left to inspect after FDNY put the fire out. This was a total loss and insurance accepted the photos without physically inspecting the car. The car began to sound like it was running on diesel and lost power shortly before the smoke. No other obvious warnings or signs were noted.
