Kia Seltos 2021 — Problemas relatados

Recall SC209-SC336. Significant blow by, engine tapping. Told by Kia service department that nothing done unless engine failure. So, I’m supposed to wait to experience engine failure while traveling 60+ mph down highway risking possible crash before problem corrected.

The contact owns a 2021 Kia Seltos. The contact stated that while driving, the vehicle unintendedly accelerated and the vehicle shut off unexpectedly. Additionally, while at a stoplight, the vehicle was jerking and vibrating before shutting off. The contact was able to restart the vehicle and continued driving normally; however, the failure recurred. The check engine warning light remained illuminated. The cause of the failure was not yet determined. The failure mileage was 166,248.

The contact owns a 2021 KIA Seltos. The contact stated that the vehicle was consuming engine oil and needed to be topped off regularly. The manufacturer was notified of the failure. The vehicle was taken to a dealer where it was diagnosed with oil consumption failure. The technician stated that the engine was consuming one liter of oil every 1,000 miles. The contact stated that there was a persistent abnormal burning oil odor. The contact stated that the engine had seized on several occasions while making abnormal sounds. The contact stated that the oil consumption failure had started since the vehicle was purchased. The contact associated the NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling); with the failure; however, the VIN was not included in the recall. The failure mileage was 110,000.

This complaint concerns the ineffectiveness of the recall remedy for NHTSA campaign SC336 (Kia recall for incorrectly manufactured piston oil rings in 2021-2023 Soul/Seltos vehicles; remedy is dealer inspection, engine replacement if necessary, plus piston-ring noise sensing software). The vehicle was purchased new in XXX. On XXX, the vehicle was brought to the Kia dealer in [XXX] for the SC336 recall remedy. The dealer kept the vehicle for 30 days and returned it on XXX. After the recall repair, the vehicle exhibited the exact same symptoms as before (excessive oil consumption / engine malfunction) - the recall remedy was ineffective. The engine defect symptoms persisted unchanged. The complainant subsequently surrendered the vehicle and no longer possesses it. No crash, fire, injury, or death resulted from this complaint.

The vehicle experienced a sudden loss of motive power and triggered diagnostic trouble code P1327, which indicates severe internal engine damage and bearing failure monitored by the Piston-ring Noise Sensing System. This vehicle is subject to active Safety Recalls SC209 (NHTSA Campaign 21V259000) and SC336 (NHTSA Campaign 25V099) for manufacturing defects in the 2.0L Nu MPI engine piston oil rings. The vehicle is currently grounded at an authorized dealership, Kia of North Austin. The Service Manager initially provided an out-of-pocket engine replacement quote exceeding $8,000 instead of processing it as a $0 safety recall claim. Furthermore, the dealership is currently attempting a diagnostic bypass maneuver to attribute the P1327 recall engine code to a "faulty knock sensor" in order to issue a paid out-of-pocket bill. The manufacturer and dealership have failed to provide a mandated loaner or alternative transportation, causing a severe and ongoing family transportation hardship while the safety recall verification stalls.

I am reporting a violation of safety recall SC336 for my car (VIN: [XXX]), which is currently at West Hills Kia in [XXX]. My engine will not start because the camshaft and timing parts broke. This happened because the engine ran too low on oil and lost oil pressure, which is exactly what this recall is about. Because the car cannot start or run, the dealership cannot do the standard electronic vibration test. Instead of asking Kia Corporate for manual approval to replace the engine, the dealership is trying to force me to pay $5,000 out of pocket to fix the camshaft first. Forcing a customer to pay thousands of dollars to fix parts that broke because of a recalled factory defect is wrong. I demand that Kia Corporate bypass the running test and approve a free engine replacement immediately INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Kia Seltos. The contact received notifications of NHTSA Campaign Number 21V259000 (Engine) and 25V099000 (Engine and Engine Cooling). The contact requested that the manufacturer and selling dealer buy back the vehicle due to recurring issues. While driving, the check engine warning light illuminated and started flashing. The contact pulled over and took the vehicle to a local dealer, where the engine was replaced. However, the failure reoccurred. While driving to the dealer, the vehicle stalled while entering the dealer. The contact stated that even though the engine had been replaced, the recurring failure raised concerns about the safety and reliability of the vehicle. The failure mileage was approximately 70,000.

Turned rear defroster on before getting on the highway as temps were in the upper 30s. About 5 minutes down the highway there was a loud pop sound and the rear windshield began splintering. By the time we got to a safe place to stop the entire shield was shattered and there were several holes. Purchased trash bags and tape to cover the windshield and during the process most of the glass had fallen a part. We had a 3 hour drive home without being able to see out the rear.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, the check engine, oil pressure, and charging system warning lights were illuminated, and the vehicle stalled. The contact stated that after waiting several minutes, the vehicle returned to normal operation. The vehicle was taken to a dealer, where it was diagnosed that the exhaust camshaft and alternator needed to be replaced. The contact stated that in July 2025, the vehicle was taken to a dealer and was inspected under NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling); however, the vehicle had passed inspection and was not repaired. The contact believed that the failure was associated with the recall. The manufacturer was notified of the failure by phone and opened a case. The failure mileage was approximately 107,000.

As I was driving my 2021 KIA SELTOS LX AWD, at approximately 45 mph, my car had stalled causing an injury to my facial area, specifically my nose.

RECALL EVASION & TIMELINE FRAUD REPORT Filing formal complaint against Kia America & Kia of Cerritos (CA) for evasion of mandate under Safety Recall SC336 (NHTSA 25V099). 1. CRITICAL TIMELINE: • [XXX]: Kia Cerritos confirmed NO diagnostic/recall tests were performed. • [XXX]: Dealer documented engine is completely SEIZED from the "bottom part" (where recalled piston oil rings reside). • [XXX] Kia Corporate denied repair, claiming the vehicle failed/passed an electronic KDS vibration test. 2. TECHNICAL IMPOSSIBILITY & FRAUD: It is mechanically impossible to run a noise vibration test on a seized engine that cannot crank or turn over. Either Kia Cerritos falsified records or Corporate is fabricating diagnostic data to evade a mandatory recall. 3. UNLAWFUL WARRANTY CONSTRAINTS: Kia Corporate is trying to route this federal safety recall through standard powertrain warranty rules, denying coverage over a lack of private cash maintenance receipts. Under federal law, safety recalls cannot be conditioned on consumer maintenance history or second-owner limits. 4. VIOLATION OF FACTORY PROTOCOL: Page 2 of Kia’s official SC336 TSB explicitly commands that a 'Seized / No Inspection' engine status must bypass the electronic noise vibration test entirely and be fast-tracked to corporate Techline for a full long-block replacement authorization. REQUESTED ACTION: I request the NHTSA Recall Enforcement Division immediately investigate Kia Corporate Case Number [XXX] for recall evasion and compel Kia America to authorize a free long-block engine replacement. "Note: This complaint is being managed by the driver's son-in-law and authorized representative [XXX] due to a language barrier."

Burns a lot of oil bad piston rings, and cylinders # 25v099000/KIA#SC336 incorrectly manufactured parts

The contact owns a 2021 Kia Seltos. The contact stated that the vehicle was experiencing excessive oil consumption. While driving 55 MPH, the vehicle lost motive power in the middle of the highway and came to a stop. The check engine warning light was illuminated, and an abnormal burning odor was coming from the vehicle. The vehicle was pushed to the side of the road with the assistance of a bystander. The vehicle was able to restart but was undrivable. The vehicle was towed to the dealer, who informed the contact a week later that the vehicle was operable. Upon retrieving the vehicle, the check engine warning light was still illuminated, and the vehicle was barely operational and made abnormal sounds. The contact informed the dealer of the issues, and the vehicle remained at the dealer and was diagnosed. The vehicle was diagnosed with camshaft failure. The vehicle was in the process of being repaired; however, the contact was informed that the repair was not covered under NHTSA Campaign Numbers: 21V259000 (Engine) or 25V099000 (Engine and Engine Cooling). The recall repairs were previously performed. The contact stated that the recall remedy failed to correct the issues. The manufacturer was notified of the failure by phone, but a supervisor had not yet returned the call. The failure mileage was approximately 158,000.

NHTSA SAFETY COMPLAINT Vehicle: 2021 Kia Seltos VIN: [XXX] Date: December 16, 2025 Complainant: [XXX] I am filing this formal safety complaint regarding serious and recurring engine problems with our 2021 Kia Seltos, VIN [XXX]. We have attempted repeatedly to resolve these concerns through Lithia Kia in Nampa, Idaho, as well as through Kia corporate, but our concerns have not been adequately addressed. Over approximately the past year, the vehicle’s engine has unexpectedly seized or shut down four separate times while the vehicle was being driven. Each incident created a serious safety hazard because the vehicle suddenly lost power. Fortunately, on these occasions, the failures occurred while we were traveling in slower traffic and we were able to maneuver the vehicle safely onto the shoulder. We are extremely concerned that a future occurrence could happen at higher speeds or in heavier traffic, potentially resulting in a serious crash or injury. Following each incident, the vehicle had to be towed. On two occasions, it was towed to an independent mechanic, and on two occasions it was towed directly to the Kia dealership. The independent mechanic diagnosed the vehicle as burning excessive amounts of engine oil. The loss of oil has occurred even within approximately 1,000 miles of an oil change when the engine had been properly topped off. We were informed that the excessive oil consumption was associated with the vehicle's safety systems shutting the engine down. Despite repeatedly reporting this dangerous condition to Lithia Kia, we do not believe the dealership has adequately investigated or corrected the underlying problem. On multiple occasions, the dealership performed relatively minor repairs, but those repairs did not resolve the problem. After the vehicle was returned to us, the same serious condition recurred. We repeatedly communicated to the dealership our extreme concern that this vehicle is unsafe to operate because the INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to file a formal safety complaint against Kia America and Rohrman Fort Wayne Kia regarding a failure to remedy a safety defect under federally mandated Recall SC336 (NHTSA Campaign Number: 21V259000 / Piston Oil Ring Defect) for my 2021 Kia Seltos.Current Mileage: 83,740 miles Active Kia Corporate Case Number: XXX Statement of Safety Risk and Incident Timeline:My vehicle recently exhibited severe symptoms identical to the documented manufacturing defect: aggressive, premature engine oil consumption resulting in a severe drop in oil pressure, loss of motive power, and random engine stalling while driving.On XXX, due to the extreme danger of operating a vehicle that stalls randomly in traffic, the vehicle was towed directly to Fort Wayne Kia (Repair Order #XXX).Failure of Recall Remedy and Dealership Misconduct:The dealership service department completed a software update tied to the recall (Piston Ring Noise Sensing System / PNSS) and claimed the vehicle "passed" their computer sensor threshold. However, the physical reality is that the internal mechanical damage from the factory defect had already occurred. Upon attempting to retrieve the vehicle on their lot, the engine failed to maintain a baseline idle and died immediately upon startup.The dealership’s Service Manager, [XXX], has refused to perform the necessary physical diagnostic engine inspections or a mechanical teardown under the recall campaign framework. Instead, the dealership attempted to charge me an out-of-pocket, customer-pay diagnostic fee of $190.00 to read the ensuing engine fault codes (P001700 and P000B00).As a professional automotive technician, I recognize these codes (Crankshaft/Camshaft Correlation and Camshaft Position Slow Response) as the direct, downstream hydraulic consequence of the top-end INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Had the software update for piston recall in April 2025, did all the testing and getting codes p0300 all the way to p0305 being that it only has 4 cylinders a 5th cylinder misfire code leads to piston ring failure, it is also burning oil the spark plugs are ashy which I have photo evidence of all of this and they are covered in oil, my car broke down while driving and lost complete engine power I am medically complex. Dealerships are denying the recall as it was "completed" due to a software update. This is a known safety hazard and I could have died. I have all proof it's the spark plugs failing.

My check engine light went on and the vehicle was driving sluggish, was louder at higher rpms and had a rough idle. The light went on around Aug 1st, 2026 and that's when I noticed the strange driving. Brought it to my mechanic that week and they got the following codes: p0017, p0014 and p0013. My mechanic thought this may be consistent with other engine issues Kia's had around the year of my car's make. While waiting for an appointment with a dealership, my car stalled out while I was driving it on Aug 5, 2026 and wouldn't turn back on. Luckily I was not on a busy road or a highway when this happened and was able to pull over without injury or damage to the vehicle. I got it towed to a Kia dealership and they took the engine apart and found that a camshaft dowel backed out causing separation inside of the engine. They had to then replace the exhaust cam, phaser, timing chain tensioner and all seals and gaskets needed for the repair. The dealership seemed to know this was a common issue and a quick search on the internet confirms that many other people with Kia engines (particularly Kia Seltos) around 2019-2021 have also had this problem. The car is 6 years old and only has about 85,000 miles on it. It has had all the required maintenance up to this point. The engine disassembling itself on its own does not seem like typical wear and tear to me.

Severe Safety Hazard, Corporate Negligence, and Delayed Repair: * After picking the vehicle up following the secondary service, a heavy, toxic smell of raw gasoline began pouring directly through the cabin’s HVAC vents while driving. * I immediately called the dealership. A representative consulted a technician and dismissively told me that the "engine just needed to be broken in." * Acting on this negligent advice, I continued operating the vehicle. My [XXX] son rides in this car daily. Due to inhaling raw fuel vapors, both my toddler and I suffered acute physical distress, experiencing severe headaches and dizziness. * On XXX I returned the vehicle to Kia of Greenville to demand an inspection regarding the toxic fumes. The dealership finally admitted that a fuel ring was broken, exposing my cabin to hazardous vapors. While the dealership has since corrected and repaired this gas issue, it only occurred after my family was subjected to unnecessary physical harm due to the technician’s initial dismissal.

My 2021 Kia Seltos is experiencing engine sputtering/hesitation at approximately 3,000 RPM and the low oil pressure warning light illuminates while the vehicle is stopped or idling. The vehicle has been taken to an authorized Kia dealership for diagnosis. The dealership opened a Kia Techline case and advised us that the vehicle passed Kia's piston-related test, but the symptoms remain. The vehicle is affected by Kia safety recall SC209, which concerns improperly heat-treated piston oil rings that may damage the engine. Kia's recall documentation identifies illumination of the oil pressure warning lamp as one of the potential symptoms/consequences of this defect. Despite the continuing symptoms, including the oil pressure warning light and sputtering at approximately 3,000 RPM, the problem has not been repaired. The dealership has now stated that Kia is requesting oil-change records and removal of the valve cover for further diagnosis. We perform our own oil changes. We were told that without service records the engine claim may be denied and that we could be responsible for approximately $878 in diagnostic charges if Kia denies coverage. I am concerned about operating the vehicle because the engine continues to malfunction and display the oil pressure warning despite being evaluated by an authorized Kia dealership. The vehicle is available for further inspection if requested.

Car began throwing a P0304 code in June of 2025. I took it to Brookshire Car Care and they ran a diagnostic, but found nothing to be wrong. In November of 2025, the car began throwing a P0304 code again and this time also had a P0303 code and P0335. The car was taken to Christian Brothers as it was unsafe to drive and the closest mechanic to my location. They found the crankshaft sensor to be damaged due to metallic debris. In March of 2026, the P0304 code came on again and I now took it to the closest Kia dealership. They determined 2 coils and all spark plugs should be replaced. Now, again, the P0304 code is back as of [XXX]. I have a long list of symptoms that include the metallic debris on the crankshaft sensor, rapid oil loss, frequent rough starts on a cold engine, a metal ticking sound, constant idle vibration, a/c shuddering when car is idle or turned on and in park. The dealership has said they will not acknowledge the findings of Christian Brothers because they are not the ones who made the repair. They said they will do a thorough test on my engine, however they continued to insist it is likely a fuel injector issue. I am concerned there is extensive engine damage and they are going to try to get out of the repair by saying it’s a cheaper fix and not determining the actual cause.

The fuel pump that is located within the fuel tank and under my seat somehow got a crack on a less than 5 year old car. I've had several people and mechanics tell me that that is rare with a car of that age. I am a safe and careful driver and purchased the car used directly from a Kia dealership. I have spent the past month trying to get a good will approval and they have denied twice even when I dont feel safe driving a car that will has parts not even exposed to the outside falling apart. My fuel pump is housed within my fuel tank and under my back seat so it is inaccessible to the average person, I have never even attempted to lift the seats. I am now left with a car I dont feel safe driving in with a large loan and a dealership and manufacturer that refuse to explain how this could happen or stand behind it. I'd also like to note that the light came on in early June so change in weather was not a factor. No extreme heat or cold at that time of year immediately prior or after it happened.

The contact owns a 2021 Kia Seltos. The contact became aware several years ago that the transmission was not shifting properly and the vehicle was shaking abnormally. The vehicle was taken to a dealer; however, the technicians found no failure. The contact stated that on another occasion while in traffic, the engine overheated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired; however, the brakes locked up while the vehicle was on a hill, forcing the contact to steer to the side of the road and turn the vehicle off. The vehicle was restarted and driven back to the residence, but the following day the vehicle stalled. The manufacturer was notified of the failures and requested that the contact return the vehicle to the dealer. The vehicle was returned to the dealer to be diagnosed. The contact was informed that the transmission needed to be replaced. The contact stated that the transmission was replaced 3 times within 3 years. The contact was informed by the service manager that the dual clutch was not ideal for driving in the mountains. The contact stated that during the first failure, there were several unknown warning lights illuminated with audible alerts to exit the vehicle. The manufacturer was notified of the failure. The dealer confirmed the transmission failure. The vehicle was not repaired. The failure continued with reduced power.

My 2021 Kia Seltos 2.0L is experiencing excessive engine oil consumption between regularly scheduled oil changes. There is no visible external oil leak or oil accumulating underneath the vehicle, but the oil level becomes extremely low before the next scheduled oil change, requiring me to add oil myself. I am concerned that continued excessive oil consumption could result in inadequate engine lubrication, engine damage, engine seizure/stalling, or loss of power while driving. I took the vehicle to an authorized Kia dealership on September 1, 2026 and reported the excessive oil consumption. The dealership did not inspect the vehicle, perform diagnostic testing, or provide a repair order. I was told that because the vehicle has approximately 138,000 miles and is outside the warranty period, there was nothing the dealership or Kia would do and that diagnosis could be expensive. I subsequently contacted Kia Consumer Assistance. Kia confirmed that safety recall SC209 was completed on this vehicle in 2021. Kia advised that this vehicle is not currently included in SC336/NHTSA 25V099. Kia has opened a dealer complaint and advised that the matter will be brought to the attention of a District Manager. I am concerned because Kia has identified piston oil-ring-related problems involving increased oil consumption in certain Kia Seltos vehicles. Although my vehicle has not yet been diagnosed and Kia states that it is not included in SC336, I am reporting the excessive oil consumption and potential resulting engine failure as a safety concern. The vehicle is available for inspection.

Acceleration is sluggish and vehicle struggles to maintain freeway speeds. Engine stalls (engine turns off, ACC still on) during normal operation. When reducing speed approaching a stop and for making a right angle turn, only the engine shuts off, all accessories (i.e. lights, climate control, radio and navigation screen) remain on. Tachometer intermittently indicates significant increase in RPM not comparable to vehicle speed. With IGS deactivated and AC off there is no change in engine stall occurrence; gasoline level is sufficient enough to not be a contributing factor and nominal amounts of engine oil is verified, yet an engine ticking is definitely audible. Oil changes (including oil filter replacement) completed every 5,000 miles, along with other milestone services in accordance with Kia preventative maintenance schedule. *there is oil burning somewhere, as the recommended amount only lasts approximately 1,000 miles; however, no noticeable traces of oil are observed in the same spot where vehicle is regularly parked. ***Three occurrences w/similar symptoms, CEL and P001700 via OBDII diagnostic scanner (attached history of dealer service and diagnostics): 1. 2024-10-11 @ 56,990 miles 2. 2025-02-26 @ 61,732 miles 3. 2026-05-01 @ 74,839 miles Each time the following parts were removed and replaced: -24370 2E020 (FP): CVVT ASSY-EXHAUST -24200 2E074 : CAMSHAFT ASSY-EXHAUS -22441 2700 : GASKET-ROCKER COVER -22443 2000 : SEAL-OIL On average, this issue occurs at 14,000 mile intervals (57k, 62k, 75k) which, with diagnostics, parts (12,000 mile part warranty), and labor adds a $2,000 cost to own annually. **Symptoms closely resemble Class Vehicle defects outlined in both: -NHTSA Campaign Number 25V099000 -NHTSA Campaign Number 21V259000 When my VIN is submitted for recall inquiry, neither campaign applies.

My 2021 Kia Seltos SX Turbo (1.6L Turbo engine) is experiencing severe, excessive oil consumption, burning (and heavy smoke ) approximately 1 to 2 quarts, (Kia dealer oil change standard amount) of oil every 1,000 miles without any external visual leaks. A formal diagnosis by a certified Kia dealership confirms that heavy carbon buildup has accumulated around the piston rings, causing severe ring distortion. Because the oil rings are stuck and distorted, the engine is bypassing oil directly into the combustion chamber and burning it. This exact physical failure mode—carbon buildup causing piston oil ring failure—is identical to the defect described in NHTSA Recall 25V099 (Kia Campaign SC336) for the 2.0L Seltos models. However, my vehicle is currently excluded from safety remedies due to its 1.6L Turbo engine variant. This vehicle presents a severe safety hazard, including sudden engine knocking, very heavy smoke from the exhaust, power loss, stalling at highway speeds, or potential engine fire due to running dry on oil. Regulators must expand the scope of the piston ring investigation to include the 1.6L Turbo engine footprint. There were no engine lights, oil lights, or any warning codes. I was told by Kia repair service department that although the car was smoking heavy and smelled like it was burning that I should continue to drive it and then I wasn’t in danger. Please help

Was driving and power steering became difficult to steer and a red steering wheel icon with a exclamation mark came on in the dashboard.

My 2021 Kia Seltos stalled twice while driving and failed to restart, creating a severe safety hazard. The vehicle was previously inspected twice at a Kia dealer for the Piston Ring Recall (SC209). The dealer diagnosis now shows timing failure codes P0014 and P0017 with misfires. The technician notes that the engine oil is entirely 'metalized' and the oil control valves are contaminated with metal debris. Kia is attempting to charge me $7,182 to fix a failure caused by the exact oil starvation symptoms of their active federal safety defect.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed and turning into the driveway, the check engine warning light illuminated, and the vehicle stalled. The vehicle was towed to the dealer, and there was no oil in the engine, and metal flakes were found in the camshaft. The contact associated the failure with NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling); however, the VIN was not included. The dealer diagnosed the vehicle with camshaft failure, timing failure and recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 71,707.

I am requesting a formal review of an engine failure involving my 2021 Kia Seltos LX with the 2.0L engine. At approximately 103,000 miles, the original engine failed after losing nearly all of its oil. There was no obvious external oil leak or oil puddle, suggesting that the engine may have been consuming oil internally. Earlier in my ownership, the vehicle also unexpectedly shut off while operating. I paid out of pocket for a replacement engine and installation. Within approximately one to two hours of receiving the vehicle back, the check-engine light began flashing. The diagnostic information reportedly indicated piston noise, even though the replacement engine appeared to run smoothly. These circumstances appear similar to the piston-ring condition described in safety recall SC336/NHTSA 25V-099, including excessive oil consumption, cylinder damage, abnormal piston noise, engine failure, and possible loss of power. However, Kia’s online system currently shows that SC336 is not open for my VIN, and the dealer found no record that the recall had previously been completed. I understand that my VIN may not currently be included, but I am asking Kia to investigate whether my original engine experienced the same defect, confirm in writing why my VIN was excluded, and review my case for reimbursement or goodwill assistance. The failure occurred only about 3,000 miles beyond the 100,000-mile powertrain warranty, and I have already incurred substantial engine and labor expenses. Please open a formal case, review my vehicle’s production and engine records, and provide a written determination. I can supply the VIN, repair invoices, proof of payment, mileage records, maintenance documentation, diagnostic codes, towing records, and replacement-engine information.

Randomly started having engine issues in July 2026. Had an appt with Kia dealership and said my engine needed to be repaired with assumptions on what the problem is. They claimed it had nothing to do with the engine recall on my Kia and that it was my responsibility to pay for the repair. There has been 2 separate recalls on this car for engine issues which Kia is refusing to deal with or take care of. My car has been serviced by Kia dealership since I bought it in 2020, I also noticed in all my service receipts/reports that they were putting the wrong oil in my car and who knows if that is what caused my engine to start having issues. Car is unsafe to drive.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at 45 mph the engine experienced a complete loss of automotive power, and no warning lights were illuminated. The vehicle was towed to a local dealer where it was diagnosed and the contact was advised that the engine was faulty and needed to be replaced. The contact associated the failure with NHTSA Campaign Number : 25V099000 (ENGINE AND ENGINE COOLING). The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 120,000.

While driving normally at approximately 55 mph on the highway, the vehicle suffered a sudden, catastrophic, and spontaneous structural failure of the rear driver-side suspension and drivetrain. Without striking any road debris, potholes, or other vehicles, the entire driver-side rear wheel, wheel assembly, and structural axle components completely fractured and ejected from the moving vehicle. An eyewitness at the scene explicitly confirmed the nature of the failure, stating on video that they observed the 'entire rear axle just come right out' while the vehicle was in motion. The vehicle sustained extreme structural damage, completely disabling it on a high-speed highway and creating an immediate, life-threatening situation. The vehicle is a low-mileage Certified Pre-Owned (CPO) unit with under 24,000 total miles on the odometer, indicating a severe manufacturing, material, or component fatigue defect rather than wear-and-tear. There were no warning lights or symptoms prior to the failure. The vehicle is currently being held at a recovery yard and is fully available for inspection upon request. A formal defect investigation has been initiated with the manufacturer, and the insurance provider is inspecting the sheared axle and metal components for structural forensic analysis

The contact owns a 2021 Kia Seltos. The contact stated that on March 13, 2026, the vehicle was serviced under NHTSA Campaign Number: 21V259000 (Engine); however; the spark plugs were not replaced when the vehicle was repaired. The vehicle was taken to the dealer, where it was diagnosed with a misfire in the engine associated with the spark plug. The dealer stated that the failure was not associated with the recall. The contact stated that the failure was caused by the dealer not installing new spark plugs during the recall repair. The manufacturer was made aware of the failure and stated that the recall repair was performed and was out of warranty. The failure mileage was approximately 92,000.

The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that while the technician was attempting to start the vehicle, the engine seized, and the contact was informed that the failure was not associated with the recall. The manufacturer was made aware of the failure, and a case was filed. The vehicle was scheduled for a diagnostic test at the dealer. The failure mileage was approximately 77,500.

Car cutoff. Started back up to get off interstate. Saw smoke under hood and got it. Within 5 min sparks under the frame and then 10-15 min later flames

Purchased new, Feb, 2020. Received piston ring defect recall notice (SC209). Serviced by dealer July, 2021. In 2025, noticed engine knocking noise. Car stalling out. No warning lights. Car 3 quarts low on oil. Consumption tests proved excessive oil used. Piston ring soak (Kia's "solution") did nothing to reduce oil use. After ring soak, oil still low at 1000 mile test. I stressed my belief the engine needs replacement and a ring soak is a band aid, NOT a permanent fix. Was asked to drive 3000 miles, check the oil, and top off if necessary. The engine was noisy during this test. At the 3000 mile mark, I pulled the dipstick. Bone dry. Drove to the dealer and told them it was very low. They sent me to the lounge and said they would pull the car in and come get me. When they didn't come, I went to check, to find a service rep putting oil in my car out in the parking lot. He claimed it was only about one quart low. Then, another consumption test at 1000 miles. Low again. They wanted to do another 1000 mile check after this. They changed the oil and told me to come back at 1000 miles. When I came back, I asked to be present to witness the oil level. They took me to the lounge, said they were pulling the car into the shop, and would come get me. Again, they pulled the stick without my presence, and told me it was full. Now, they want me to do another 4000 mile test. I took the vehicle to two independent mechanics. Their borescope inspection proved engine damage. I have filed a complaint with Kia Corporate and it seems to be falling on deaf ears. I demand a full refund at this point! Kia has lost my trust, both in quality and customer service. I have all the maintenance records and a written statement regarding engine damage, along with photos from the borescope.

After getting recall work done last year regarding SC336 my sensor went off and now my car needs a new engine due to defective heat-treated Piston oil rings causing Catastrophic failure. Kia is declining responsibly because of lack of enough oil changes. They have not proved this failure was from neglect.

Just purchased a used 2021 KIA seltos with about 45k miles. I did my research and checked prior if there were any major issues. Since it showed zero recalls and received relatively good reviews I thought it would be a safe and reliable vehicle. I was wrong.I had the vehicle for only about three months when I noticed the check engine light come on while driving on the freeway. It was solid, however, I thought it was better to be safe than sorry and started to look for an exit. While driving up a freeway interchange the car suddenly started to lose speed. I pressed the accelerator but couldn’t get any power to the engine. As the car started to slow rapidly I pulled over to a narrow strip of the road. This was a dangerous stretch of the freeway because there was virtually no shoulder and cars were accelerating to merge up the rising ramp on the stack. After I came to a stop I put the car in park and turn it off. I then tried to restart the engine but had no luck. The engine would crank but would not start. I was now stuck and getting anxious as traffic began to steadily increase. Cars were flying by at high speeds less than a foot away. I had no choice but to call for a tow truck and patiently wait. I sat there praying that nobody would hit my car. I was fortunate to be safely towed to a service center.The technician performed a borescope and found severe scoring on the cylinder walls directly relating to defective piston rings. The improperly heat-treated piston rings chipped and literally carved deep grooves into the block dropping the compression causing the car to sputter and die.The engine has internal damage and will not start. Needs a new long block (Engine replacement). There is a recall on these piston rings.The dealership sent in their inspection including compression test and borescope images showing the groves and scoring on the cylinder walls. KIA is refusing to cover cost because the car is out of warranty. Safety recalls never expire with warranty!!!!!!

Car was driving absolutely fine, no dash lights no signs of distress for 1.5 years then suddenly out of the blue it made a "weird noise" -no lights on dash board, and it went away. Two days later my daughter was sitting in a fast-food line and the car just died. They had to push her out of the line. She turned the car off and when she turned it back on it started up and she drove home. We made an appointment to have it looked at but with in two days before getting to the appointment it happened again, same thing different place so she drove it home. it was looked at by Pep-Boys they told us it needs a new engine. Referred us to the recall of the Seltos 2021. We then towed it to Kia Dealership and they have confirmed it is the engine and that it needs to be replaced. The car is doing exactly what the recall was specified for and they are asking us to pay because the vin number of my daughter's car is not included in the batch of vin numbers recalled. My daughter's safety was compromised by the faulty manufacturing, the car has less than 60 thousand miles on it. We are the second owner, bought at Carvana and was certified by Carvana. I wanted to file this report to ensure all options have been explored for KIA to be held accountable for the repairs. Luckily my daughter was not hurt or endanger, but it could have easily been another story.

The contact's daughter owns a 2021 Kia Seltos. The contact stated that the vehicle was consuming an excessive amount of engine oil. No warning light was illuminated. The contact stated that one quart of engine oil or more needed to be added after an oil change had been performed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact associated the failure with NHTSA Campaign Number: 21V259000 (Engine); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 25,000.

My 2021 Kia Seltos 1.6L Turbo GDI is experiencing a severe safety hazard involving catastrophic internal engine failure. The vehicle aggressively consumes its oil supply, running critically low within 1 to 2 weeks. On July 6, 2026, a certified Kia dealership pressure-tested the engine and formally documented "NO EXTERNAL LEAKS," while confirming the spark plugs are entirely "OIL COATED" due to severe internal burning. The dealership noted on the invoice that the vehicle was "9,000 miles due" for service. I must explicitly clarify that this mileage gap occurred because the engine burns through its oil so rapidly that standard interval changes became meaningless; I was forced to continuously top off the engine manually out-of-pocket with store-bought oil just to keep it from running dry and seizing while driving. Otherwise, all other oil changes were consistently done at Kia dealerships, and this excellent service history was even explicitly acknowledged and noted by a Kia Consumer Care representative on a recorded line. Furthermore, the engine builds extreme crankcase blow-by pressure that actively forces oil vapor out of the oil filler cap. This defect creates an immediate risk of sudden engine seizure, highway stalling, or an engine bay fire. Kia Corporate Consumer Affairs has refused to authorize safety repairs or diagnostic testing under TSB ENG222, issuing a blanket denial while ignoring an imminent safety failure diagnosed by their own technician.

My engine is damaged and needs replacement. My car starting stalling, when I put the car in reverse the car would stop working, the car starting vibrating and my check engine light came on. When I took it to Southwest Kia dealership, they pulled the recall and stated that the symptoms I was experiencing were what was described in the recall. However, the warranty has refused to repair the recall. I have been without a car for almost 6 weeks. The warranty keeps saying my VIN is not associated with the recall.

The contact owns a 2021 Kia Seltos. The contact stated that while driving uphill at 45 MPH, the check engine warning light illuminated. The contact attempted to pull over, and the vehicle experienced engine failure. An independent mechanic or dealer was not contacted. The vehicle was not taken to an independent mechanic or dealer to be diagnosed. The contact checked the oil, and there was no oil on the dipstick even though the vehicle had received an oil change two months earlier. The contact called a friend to top off the engine oil. The manufacturer was notified of the failure and informed the contact that there was no recall associated with the VIN. The contact was informed that the vehicle had been repaired in 2021 before owning the vehicle. The approximate failure mileage was 96,070.

The car has less than 50,000 miles on it and the transmission is malfunctioning. Something about the dual clutch system losing protection. It has lost more than 70%. I knew there was a problem when the car reported transmission temp hot.

My Kia has been stalling, shaking, and just driving extremely badly for the past year. This day, I was driving on 55, and the car just stopped and stalled in the middle of highway near Berwyn, IL. This was extremely dangerous and could have honestly been life threatening. I pulled over, turned the car off and on, and was safely able to drive it to Berwyn Kia. Unfortunately, this was not the only time that this has occurred and I’m assuming will not be the last. In addition, I was charged $500+ to replace piston rings that were recalled on other models that were not recalled on my model, even though the same year was recalled.

The oil pan is consistently out of oil. It burns up. Causing the engine to stall, shake or grind at times. We have been having this problem for 2 years now. Taken it to 2 different dealerships. They confirmed it needs a new engine however Kia will not replace it for us. It is a known problem with these vehicles and there is a lawsuit currently going on. We have receipts from dealerships, we have been stranded on the side of the road many times and can not drive it due to risk of fire or engine seizing. We used to keep oil in the car at all times and check it frequently. Now we are afraid to drive it and damage it any more. We have done all the recalls and because the one recall was a piston ring system update, we aren't covered under the recall then. The system must be faulty. We do get a check engine light or oil light on when the car stalls, otherwise we just have to keep watching the oil that keeps disappearing. Kia has denied us the new engine after asking for an Out-of-Warranty Goodwill Breakdown for the car. The first owner went 10,000 miles without seeing a dealership and we did as well when we first bought it. The problems started at 57,700 miles. The car is junk and they wanted to give us a deal on the new engine $7,750 out the door. WOW, it's not our fault the engine or the piston rings burn the oil and are burning the engine up. Kia is at fault, their cars are crappy.

I am unsure what part of my car malfunctioned. I had my foot on the brake when my car began to surge forward and accelerate itself, crashing me into a tree because the steering completely stopped working as well. It is available for inspection upon request. My safety and the safety of others was put at risk because I was in the middle of the street. The problem has been confirmed by an independent service center. A couple days after the incident, the same exact malfunction happened to an employee at the independent service center. The vehicle was lightly inspected by the manufacturer but there isn't a concise conclusion as to what caused the issue. There was not any warning lamps or messages before the incident. My airbags did not deploy during the incident even though there was significant damaged to the body of the car. A couple days prior to the incident, I was at a complete stop at a traffic light. As I had my foot on the brake, the car began to surge and jerk forward itself.

I was driving on the highway at 63 mph. I went to change lanes and pass the vehicle next to me so I gradually went up to 75 mph. Then there was an explosive metal sound and white smoke filled my cabin and under my hood. I could smell oil from inside the vehicle. I pulled over, opened the hood and let it cool off. After it cooled off I checked the oil and found there was none. I then called roadside assistance through my maxcare extended care plan. They sent a tow truck to pick up the vehicle and sent it to the nearest auto shop which is called precision tune auto roughly 1.8 miles away from where the car was parked. The tow truck dropped it off at 11pm. I called the next day in the afternoon to provide my contact information and wat happened. They ran a diagnostic on the vehicle and said either a piston or rod blew through the oil pan which caused all the oil to leak out from underneath the car and said the engine needed to be fully replaced.

The contact owns a 2021 Kia Seltos. The contact stated that while the vehicle was at a complete stop with the brake pedal depressed, the vehicle unintendedly accelerated and crashed into a tree, where the vehicle came to a stop. The contact stated that the brake pedal remained depressed during the failure. While being placed on the tow truck, the vehicle violently jerked. The contact stated that while the vehicle was at the collision center for repair, the vehicle unintendedly accelerated while being moved. The contact stated that the brake pedal was depressed during the failure, with both feet on the brake pedal; however, the vehicle continued driving. The failure had occurred a second time while stopped at a red traffic light with the brake pedal depressed, and the vehicle had unintendedly accelerated. The vehicle was towed to a collision center. No warning lights were illuminated during the failure; however, the engine was revving unexpectedly. A Police report was filed during the crash. The vehicle was deemed unsafe to drive but the insurance company towed the vehicle to a Kia dealer where the vehicle was diagnosed with transmission failure. During the crash, the contact sustained injuries to the abdomen, left knee, and left thigh, with severe pain in the lower back. Several days following the crash, the contact had pain in the chest. The contact received physical therapy for the injuries. The contact previously suffered from PTSD. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 55,000.
