My 2021 Kia Seltos with the 1.6L turbo engine is burning an excessive amount of oil — about one quart every 800–1000 miles — and is showing blue smoke from the exhaust. A certified technician indicated that the likely cause is faulty piston rings, which is a known issue on this engine and has led to engine replacements in other Kia vehicles. The vehicle was purchased as a Certified Pre-Owned Kia, and I have maintained it properly. Despite this, Kia and the dealership and the certified preowned warranty company have denied warranty coverage, calling it "oil consumption," even though the oil loss is clearly excessive and mechanical in nature. This defect poses a potential safety hazard, as engine failure or oil-related fires could occur if the engine runs low on oil while driving. There are many similar reports online from 2021 Kia Seltos owners experiencing the same problem. I am requesting that the federal safety agency investigate this issue and require Kia to address these engine defects, as they appear to be widespread and potentially dangerous.
2021 Kia Seltos engine complaints

Recall was initiated for my 2021 Kia Seltos for potential defective engine piston rings which could lead to increased oil consumption and lead to damage/fire to engine compartment. My vehicle has been burning through oil to the point i have to add it weekly to keep it from running out before next scheduled oil changes. Two separate local mechanics confirmed this is highly indicative of bad piston rings and should definitely be covered for repair/replacement by Kia dealer under recall. I took car in for recall assessment, they stated they performed an oil consumption test and engine knocking test to which they deemed it passed. I spoke with lead mechanic explaining that the car is burning through oil so quickly it would be completely empty by next scheduled oil changes if i wasnt continuously adding it - to which they replied they were aware and to "just keep adding oil". I stated this didnt seem right as it we know it is burning up oil at an alarming rate inside engine and was told unless it is pretty much spewing oil on the floor in front of us, it will pass the consumption test and you just have to continue adding oil. The piston rings would not even be checked unless you "failed the oil consumption test first". This is very concerning to drive now since there are reports of this issue leading to engine fires.
I bought this vehicle brand new in 2021. I noticed at the beginning that when I accelerated that the car would delay in acceleration. This would happen sporadically. Now it is happening all the time and has almost caused me to get into several accidents because of the delay in acceleration. This is a major safety risk. I've had the car inspected at Kia Dealers and they just say yeah, we hear that a lot with this model but there is no recall. There are no warning lamps or messages.
The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle stalled. The contact stated that unknown warning lights were intermittently illuminated. The vehicle was taken to an independent mechanic, and the contact was informed that there was less than one-quarter of oil in the engine. The contact stated that an oil change was performed. The vehicle was repaired. The contact was advised to take the vehicle to the dealer for further services. The contact was advised that the vehicle should not consume 3.5 quarts of oil within 5,000 miles. The vehicle was taken to the dealer; however, the vehicle was not inspected. The dealer was informed that the vehicle was consuming 3.5 quarts of oil within 5,000 miles. The contact was informed that it was not an issue. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000.
The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound coming from the vehicle. There were no warning lights illuminated. The contact was informed about the federal safety agency Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was taken to an independent mechanic for an oil change. After leaving the mechanic, the vehicle started smoking, and the engine seized in traffic. The vehicle was towed to the local dealer, who determined that the engine was faulty and needed to be replaced. The vehicle was not repaired. The dealer informed the contact that there were no oil change records for the vehicle. The manufacturer was contacted and notified of the issue. The failure mileage was unknown.
After being stopped while driving when the car turns off, when re-starting sometimes the car will turn off, I have to put my car into park in the middle of the street to restart the engine. Other times, it will start alerting me to "push the start button" as if my car isn't on already. This causes me to come to a complete stop in the middle of the intersections and puts me at risk.
Was driving about 25 30 miles an hour coming to a stop and it stalled out all break power and everything cut out managed to get the car stopped and started again but looking it up not on nation recall list but it’s giving me the same problems on the recall list have replaced the battery starter they said flywheel and alternator are okey I haven’t made but one payment on the vehicle also chef oil and all that currently fine
The engine (62K miles on it) on this vehicle is consuming oil very fast. We took this in several times to no avail but we finally received documentation from Kia stating the issue, we took it in for tests and the Kia Dealership has confirmed it needs a new engine. However Kia is denying the new motor due to missing one oil change document. This was done by my daughter's boyfriend and was done. However, they did not keep the receipt BUT we did have documentation on all other oil changes. This issue with the motor is NOT an issue of a receipt but due to Kia's poor manufacturing. It has improperly heated treated piston oil rings. Regardless of one miss receipt, this should be covered. There is also an audit with the NHSA for the issue.
I just bought the car in July used from Honda there rates on extended warranty for the car at the time were outrageous but since buying it it’s been stalling hard starting throwing engine codes after a month and throwing all the power train warning that we’re a part of the recall with it doing that even giving me all the driving assist warnings I don’t currently have a good picture of what’s going on or video but I’ve replaced the starter and battery an it didn’t fix the issue Honda is saying take it to Kia and Kia is saying take it to Honda and I’m not getting any answers with that either I just know from people I’ve talked to that’s had the car t a point said there’s was recalled and it fixed those issues with one of them mines just also not on that list
We received the federal safety agency recall # 25VO99 letter from KIA America Corporate Headquarters, dated April 4, 2025. We called the service department at the local Kia dealership, and were told "Don't bring it in, hold off, they were not doing this at this time, KIA is doing it a different way." It seemed odd at the time, since we were following KIA's recall instructions: "In the interest of the safety of your passengers, as well as your own safety, contact your local KIA dealer to arrange for the recall to be performed." In early September, we had stopped driving the car and had it towed to the same service department because we heard a ticking noise in engine, and stalled out - no lights on the dashboard ever came on indicating an engine problem. The service center, at the Kia dealership, said that the noise had nothing to do with the federal safety agency Recall #25VO99 even though it is identical to the safety recall's indicators. Instead of honoring the recall they said we needed a new long block. We were told by the service center Kia had them do a borescope inspection across cylinders 1 through 4, we were told cylinder 3 was "really bad". They asked for our maintenance records and we were told that we voided our warranty by late oil changes along the way. We have brought the car to the same Kia dealership for all service when we moved here four years ago. To be clear the engine had plenty of oil in it when it started stalling out, and making noise. Kia is contending that the engine blew because the oil might have been dirty. They have given us no proof of this or no proof that the safety recall does not apply. This car was not even 5 years old and under the 60,000 miles. We still had 5 payments on our car loan with Kia. We were charged $6,679.15 for a new longblock engine. Kia took no responsibility for the faulty engine.
The auto stop start function of this car is very unsafe. It sometimes does not start back immediately and rolls back. It’s just very unsafe.
On [XXX], while driving my 2021 Kia Seltos (VIN: [XXX] ) on the highway at approximately 70 MPH, the engine suddenly revved slightly higher and then completely shut off without warning. This caused a loss of power, making the vehicle difficult to control and nearly resulting in a significant accident with surrounding traffic. Fortunately, I was able to coast and pull over to the shoulder safely, avoiding a collision. No warning lights illuminated prior to the incident, and there were no other noticeable symptoms beforehand. The vehicle was towed to Classic Kia in Texarkana, TX, where technicians diagnosed engine seizure with no oil present—a clear symptom of excessive oil consumption and cylinder wall damage linked to faulty piston oil rings. During a call with Kia on September 16, 2025, they confirmed two prior recall repairs in 2021 and 2022: one for Recall SC209 (the federal safety agency 21V‑259, addressing piston oil rings in 2021 Seltos with 2.0L Nu MPI engines) and another related repair not directly tied to SC209 but addressing similar engine issues. These repairs failed to prevent the defect, as evidenced by the seizure. This matches the piston ring defect in SC209 and the expanded Recall SC336 (the federal safety agency 25V‑099, covering 2021–2023 Seltos), which can cause seizure and fire risk. the federal safety agency’s 2025 audit of Kia’s engine recalls notes ineffective fixes, with owner complaints of post-repair failures. This incident posed a severe safety hazard, as engine seizure at highway speeds risks crashes, injuries, or fatalities. I urge the federal safety agency to investigate this as part of the audit and compel Kia to provide a permanent remedy, such as engine replacement or vehicle buyback under warranty/lemon laws.

We bought a 2021 Kia Seltos new from Spitzer Kia Cleveland (June 2020) and kept up with regular maintenance. The vehicle is subject to two the federal safety agency recalls for defective piston oil rings (21V259000 in 2021 and 25V099000 in 2025; Kia SC209 & SC336). Component/system: piston oil rings and related engine parts. Vehicle is at Spitzer Kia and available for inspection. Timeline: [XXX] – Check engine light illuminated (solid). Dipstick dry. Dealer said likely recall issue. [XXX] – Vehicle brought to dealer. Staff first acknowledged probable piston-ring issue and possible engine replacement. Later same day they switched to an “oil consumption test” requiring us to drive 1,000 miles—possibly three rounds (3,000 miles total)—before they will even consider replacing the engine. We must top off oil ourselves during this time. Safety risk: Driving thousands of miles in a recalled vehicle with known oil-consumption defect could cause engine seizure, stall, loss of power, or fire, endangering us and others. Inspection/confirmation: Dealer inspected the vehicle 9/12/25. Manufacturer (Kia America) also contacted and gave same response. Warning lamps/symptoms: Check engine light appeared [XXX]; low oil level, no external leaks noted. We do not feel it is safe to comply with the driving tests. Dealer threatened to tow our car if we did not pick it up. We have complete service records, recall notices, and correspondence available.

Was driving home and vehicle started to sputter shut off. There were no warning lights or messages. Took to the dealership, who was aware that there is history of this with Kia, but my VIN was not included in recalls.
The contact owns a 2021 Kia Seltos. The contact stated that while driving at undisclosed speeds, the vehicle stalled but restarted. There were no warning lights illuminated. The vehicle was taken to the Inspection Station for a yearly inspection, which confirmed an upcoming recall, and was unable to be repaired. The vehicle was taken to the local dealer, but the vehicle was not diagnosed or repaired. The contact received the notification of the federal safety agency Campaign Number: 25V099000 (Engine and Engine Cooling). The manufacturer was contacted and requested the oil change records. The contact was able to provide records for a year. The manufacturer declined the repair. The failure mileage was approximately 45,000.
In January my husband was driving the Kia and it broke down. We took it to the mechanic and they said it was completely out of oil. Spent $5,000 on getting it fixed in a couple weeks later find out there's a recall. Took the Kia to the dealership in Ocala. They and told us there was nothing wrong with it and that they fixed it. It also makes noises when you turn the car on. to this day we still have to put oil in it almost every day. And it still makes a weird farting noise when you turn it on. I even asked mechanic in Ocala if it made that noise. He looked at me like a was stupid haha. And then I asked him what would happen if we still had to keep putting oil in it. He said we shouldn't have to.
My car just stopped working while driving on the road. It wouldn’t crank up/ the engine wasn’t operating and the car wouldn’t accelerate. It’s been over a year since my car hasn’t been working. I took it to the dealer and they said the engine wasn’t consuming the oil or something of that sort. No lights came on before it’s like it just went out. It has been inoperable ever since. This was June 2024.
The contact owns a 2021 Kia Seltos. The contact stated that while driving 60 MPH, the accelerator pedal was depressed; however, the vehicle decelerated. A dealer was contacted. The failure had occurred on two occasions. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The vehicle was not repaired. The contact related the failure to the federal safety agency Campaign Number: 21V259000 (ENGINE); however, the VIN was not included in the recall. The manufacturer was notified of the failure and offered to cover half of the repair in January, but recently only offered to cover twenty percent of the repair cost. The failure mileage was 65,000.
The contact's daughter owns a 2021 Kia Seltos. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to a dealer, and it was acknowledged that the failure was a known issue. The dealer recommended that the vehicle no longer be driven and remain with the dealer for additional diagnostic tests. The vehicle remained with the dealer unrepaired. The contact then received notification of the federal safety agency Campaign Number: 25V099000 (Engine and Engine Cooling); which was linked to the failure. The contact stated that several attempts were made to reach the dealer and the manufacturer about the recall repair; however, an update on the repair was not yet provided. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was 33,621.
I took my car in last Wednesday to have the recall remedy done I was told my engine was fine my car sat up after that until Monday when I turned it on the check engine light came on and I was told after checking that cylinder 2 was misfiring and apparently my car was in fact not okay. My car went in on Monday and has been sitting in “being inspected “ status since yesterday. I have called and texted multiple times and can not receive and answer as to what is going on nor did they give me a loaner so I have been with out a car for 4 days now. The service department does not answer nor return my calls and just keep routing me to scheduling who apparently can’t tell when what’s going on either.
I pulled off the main road into the Walmart parking lot. When I did, the vehicle shut off, no power and steering was very hard. I was able to steer into a space and safely park. Vehicle was towed to Victory Kia in Victoria. Service dept said there was no oil at at all in the vehicle. Vehicle was recently taken in for the Kia engine recall about 3 months ago. Was told I needed an software update and oil change to remedy the problem. I got a full synthetic oil change. The vehicle burned all the oil off. No low oil or oil warning light ever came on. Now, Kia wants me to pay for another oil change and diagnostic and drive the vehicle for 1000 miles to see the outcome. Which, if/when the motor dies out again,then I'll be stranded again, hopefully not on a freeway this time. It's crazy I have to be a guinea pig for Kia to see if when the car dies out again, hopefully it don't catch fire this time when all the oil burns out like it did last time
Kia replaced a recalled part on my vehicle related to the engine — specifically tied to the known piston oil ring defect. Before this recall repair, my vehicle was running ok with a couple time the car had completely shut off while Driving. This was back in 2023 and 2024 and was told to just add oil by the service dept. Immediately after the recall service was performed like drove it off the lot and place was already closed, the engine light came on and will not shut off, I also noticed a strange engine noise and the car leaches and can not go past 55mph. I advised the Kia dealership, and they informed me that it has nothing to do with the recall fix they did even though i did not have these issues before bringing it in and e to look it and said they would charge me over $100 to diagnose and then it would all be out of my pocket.The recall letter explicitly stated that if these symptoms were present — including excessive oil consumption or engine stalling which i have both and have been told in the past and documented to just keep adding oil in between oil changes — Kia would replace the engine at no cost to the customer. I even called kia and explained this to them to no avail and no help. Despite this, Kia is now refusing to uphold that promise and is not replacing the engine, even though the vehicle now displays all the symptoms outlined in their own recall documentation. This is both a serious safety concern and a failure by Kia to comply with recall obligations. The vehicle is unsafe to drive and could potentially cause a serious accident due to unexpected engine shutdowns at speed. I am requesting an immediate investigation into Kia’s handling of this recall and their failure to fulfill the engine replacement they promised in writing as part of the recall terms.
On June 5, 2025, Kia replaced a recalled part on my vehicle related to the engine — specifically tied to the known piston oil ring defect. Before this recall repair, my vehicle was running smoothly with no issues. Immediately after the recall service was performed, the vehicle began shutting off while I was driving, and I also noticed a strange engine noise. I returned to the Kia dealership, and they informed me that the engine is now consuming oil — a known symptom directly linked to the same recall issue involving oil ring failure. The recall letter explicitly stated that if these symptoms were present — including excessive oil consumption or engine stalling — Kia would replace the engine at no cost to the customer.

The engine on my 2021 Kia Seltos failed due to a jumped timing chain shortly after having the piston rings replaced under recall SC209. The vehicle is at a Kia dealership and available for inspection. On July 14, 2025, I contacted Kia Consumer Affairs to follow up on a GoodWill request I sent on June 25th, 2025 and KIA verbally stated the engine had been approved for replacement. When I followed up on July 21 due to lack of communication, I was told the approval no longer appeared in the system. Since then, I have received no return calls, voicemails, or emails despite explicitly requesting that a supervisor contact me directly. I was also promised a 48-hour follow-up, which never happened. This failure occurred at approximately 110,000 miles, well before a modern engine should suffer a critical mechanical breakdown. The dealership confirmed the timing chain was the cause and that the prior piston ring recall repair did not resolve the issue. The failure was sudden and puts safety at risk—if this had occurred at highway speeds, it could have caused total loss of power while driving. I rely on this vehicle as a single mother and have no alternative transportation. There were no warning lamps or dashboard alerts before the engine failed. Performance issues were present, but no early system diagnostics caught the problem. Kia’s inconsistent communication, lack of follow-through, and refusal to take responsibility after their own recall repair failed is unacceptable. I am filing this complaint to document the failure of the recall to prevent engine malfunction and the ongoing safety risk associated with this engine design.
The contact owns a 2021 Kia Seltos. The contact received notification of the federal safety agency Campaign Number: 25V099000 (Engine and Engine Cooling); however, the dealer refused to perform the recall repair. The contact stated that while driving at an undisclosed speed, the vehicle stalled while stopped at a traffic light or stop sign. The contact was able to restart the vehicle; however, several unknown warning lights were illuminated. The contact stated that on another occasion, while starting the vehicle, the vehicle vibrated abnormally, and while the brake pedal was depressed, the vehicle stalled. The vehicle was taken to an independent mechanic, and an oil change was performed. The mechanic informed the contact that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to the dealer and was diagnosed with camshaft failure, which caused engine failure. The vehicle was not repaired. The contact was informed that the warranty was not covered because the vehicle had not received the oil change at a KIA dealer, and that the oil used was of poor quality. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000. Parts distribution disconnect.
Oil pressure light illuminated, extreme engine knocking, failed acceleration power and engine stalling while driving. Towed to dealership. Was told the vehicle "passed" the oil piston ring recall test and refusal of Kia to replace engine.
In late 2024 at 45,000 miles I noticed my 2021 Kia Seltos burning oil due to an extremely low amount oil being removed during an oil change. Who knows how long it was going on. I took the vehicle to the dealership and was told an oil consumption test needed to be done. The test showed after driving 2,134 miles, the car was down 1.2 quarts of oil. That should be unheard of in a 3 year old car with low mileage. I was told it is within an acceptable amount and I should keep doing consumption tests. After month of time waiting and hours spent doing multiple consumption tests, they still will not acknowledge the clear issue with my vehicle. I then discovered there is a Kia Seltos recall which my vehicle has all the symptoms of. They performed a sc336 procedure for this recall and you guessed it, I was told nothing is wrong. Here I am a year, and a half later giving up. I now just fill the oil myself every few weeks while I wait to see what else is going to go wrong. This is TERRIBLE business practice.
KIA AMERICA, INC. IS RECALLING CERTAIN 2021-2023 SELTOS AND SOUL VEHICLES. THE PISTON OIL RINGS MAY HAVE BEEN MANUFACTURED INCORRECTLY, WHICH CAN RESULT IN ENGINE DAMAGE. Safety Risk ENGINE DAMAGE CAN CAUSE A VEHICLE STALL OR FIRE, INCREASING THE RISK OF A CRASH OR INJURY. After i was told about my recall i took my car to the Vineland new jersey Kia dealer.
