2 recalls name the 2021 KIA Seltos. Newest first.
Kia America, Inc. (Kia) is recalling certain 2021-2023 Seltos and Soul vehicles. The piston oil rings may have been manufactured incorrectly, which can result in engine damage.
Engine damage can cause a vehicle stall or fire, increasing the risk of a crash or injury.
Dealers will inspect and replace the engine as necessary, free of charge. Dealers will also install piston-ring noise sensing system (PNSS) software, free of charge. Owner notification letters were mailed April 4, 2025. Owners may contact Kia customer service at 800-333-4542. Kia's number for this recall is SC336.
Kia Motors America (Kia) is recalling certain 2020-2021 Soul, and 2021 Seltos vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which may result in engine damage.
A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
Kia will notify owners, and dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Kia will deploy Piston Ring Noise Sensing System (PNSS) software. The recall began June 11, 2021. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC209.
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
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.
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.
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.

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.
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.

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.
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 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
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 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.
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.
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.
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
On August 6, 2025, the Office of Defect Investigation (ODI) opened Audit Query (AQ) 25001 to assess the implementation of Kia America, Inc.’s (Kia) remedy program for Safety Recall 25V099, involving incorrectly manufactured piston oil rings which may damage the engine causing a loss of motive power or fire. This AQ was opened in response to consumer complaints alleging of an ineffective remedy, inconsistent inspection results to determine whether an engine replacement was needed, and the unavailability of recall remedies. On August 11, 2025, an Information Request (IR) was issued to Kia requesting: 1) why the inspection test was revised from requiring a ‘cold’ engine to a ‘warm’ engine; 2) why the recall remedy was suspended from April 30, 2025 to May 7, 2025; 3) how Kia notified customers of the recall remedy suspension and the need to re-test engines that failed the ‘cold’ engine test; 4) the number of post-recall remedy complaints alleging engine or other engine related failures; and 5) the warranty coverage Kia is offering to vehicles that passed either inspection tests. On September 10, 2025, Kia responded to NHTSA’s IR: Kia reported the change in temperature from ‘cold’ to ‘warm’ engine testing was done to increase accuracy. The inspection test uses diagnostic tools that detects abnormal engine vibrations to identify damaged engines. From the initial launch of the Technical Service Bulletin (TSB) on April 4, 2025 through April 28, 2025, ‘cold’ engine testing resulted in a higher-than-expected failure rate when compared to the pre-recall warranty claim rate. This discrepancy led Kia to re-evaluate its inspection test and found that performing the inspection on a ‘cold’ engine can result in imprecise test results due to normal cold-start vibrations. Kia revised the inspection to ‘warm’ engine testing to minimize vibration interference. Kia sampled the field and performed a comparative analysis between ‘cold’ and ‘warm’ engine testing, and validated that ‘warm’ engine testing was more accurate in identifying damaged engines. Kia also reported the suspension of the recall remedy was due to a software error in the diagnostic tool, which was introduced in concert with the April 29, 2025 launch of the TSB that revised the inspection from ‘cold’ to ‘warm’ engine testing. The software error resulted in all inspection tests reporting false positives for a damaged engine. On April 30, 2025, Kia suspended the remedy until May 7, 2025, which was when the software error was corrected with the release of the latest TSB and software update. The recall remedy remains available to eligible customers. Kia reported owners were not mailed letters concerning the suspension to the recall remedy. Kia reasoned since it resolved the issue faster than it would have taken to draft and mail letters, Kia did not want to create unnecessary customer confusion involving an issue that would have already been addressed upon receipt of a letter. Kia also determined that mailing letters about re-testing engines was unnecessary since those vehicles were already at the dealer awaiting engine replacement. In most instances, Kia Customer Care agents would respond to customer inquiries related to the recall, including remedy availability, dealer issues, and questions about differing test results. Kia provided ODI a review of engine related consumer complaints received on post recall-remedied vehicles. Kia did not find any common patterns or trends related to those complaints following completion of the recall, as the complaints included issues that were unrelated to the subject defect. To aid in the diagnosis of whether a complaint is related to the recall, the remedy includes the installation of a software program, the Piston-ring Noise Sensing System (PNSS), that monitors the engine for unusual noise patterns (an indicator of potential damage to the piston oil rings), and alerts the customer by flashing the check engine light and setting Diagnostic Trouble Code (DTC) P1327. Kia confirmed that it is not offering any specific warranty coverage for this recall. Instead, Kia has instructed dealers to replace the engine, at no cost to the customer, with no time or mileage limitation, following the installation of the PNSS software and the presence of DTC P1327. On September 4, 2025, Kia issued Subsequent Repair Action (SRA) # SC336YZ, which provided engine diagnosis and replacement instructions for vehicles with a potentially related complaint following completion of the recall. Under this SRA, customers whose vehicles set DTC P1327 will have their engine replaced. If DTC P1327 is not set and it is unclear whether the issue is related to the recall, dealers are instructed to contact Kia's Technical Assistance Center to ensure the issue is appropriately handled. Kia notes that any issues determined to be unrelated to the recall are subject to the 10-year / 100,000-mile Powertrain warranty for original purchasers and a 5-year / 60,000-mile Limited Basic Warranty for subsequent purchasers. In summary, Kia identified the insufficiencies of its initial inspection test that led to a pause to its recall campaign, explained why it did not mail letters to affected customers about the paused campaign or revised inspection test, reviewed existing consumer complaints that did not identify any potential trends related to the recall, and identified its warranty coverage for any vehicles exhibiting qualifying engine symptoms. After review of Kia’s response to the IR, ODI has determined that no further action from Kia is necessary at this time, and ODI will close this AQ investigation accordingly. The Agency reserves the right to take additional action if warranted by future circumstances.
