The car is available for inspection upon request. Safety was put at risk due to the cars potential to break down, or catch fire, due to high volumes of oil consumption and leakage from the piston rings. This was part of a recall campaign (#SC336 PISTON OIL RING), where we had two authorized Kia dealers inspect and claim the car "passed" their test. Recently, we had a catastrophic engine failure due to the piston rings, where we feel the fix was insufficient given the failure point (piston rings). There were no warnings or symptoms prior to failure, when driving at a low speed the car stalled and the oil pressure warning light came on briefly. After that, we parked the car immediately and had it towed for inspection. Our concern is the fix was allegedly implemented in July 2025, but there is no note in our maintenance record that the fix was even implemented.

This vehicle burns oil excessively. From everything I've seen says this should be under recall but the Kia dealership tells me it's not because it's over 60,000 miles and I'm the second owner. They offered to do a oil consumption test for $900. I've already read complaints about this engine locking up and people being seriously injured. I have to put oil in it every thousand miles or so. For a newer vehicle this is unacceptable and Kia should be taking care of this. This is absolutely going to get someone killed when their engine seizes. The transmission on this vehicle also has issues that have complaints littered through the message boards. KIA knows it's going to fail and get someone killed as well. They dont care as long as they get your money. Unacceptable.

The engine catastrophically failed on an 45 mph road. There was no warning leading up to this incident at any time previously. The engine lost all power and the car shut off on this road. My husband was able to pull it over and tow it into a mechanic. The mechanic said the oil was disappearing somewhere without any residue, and without triggering any warning light of any kind. In essence the oil is not low enough to trigger the light but it is also escaping somewhere. The mechanic said it seemed like the engine had a fault in it. Because of the open recall on the piston rings, we had it towed to the dealership who then claimed this problem has nothing to do with the faulty piston rings. Instead they said there is a rod knock. The car is currently at Doug Smith Kia in Lindon, Utah and can be inspected there.

My vehicle recently idled roughly and shut off at low speeds and while stopped at intersections on my way to work. I brought it to an authorized Kia dealership the very next day. After researching my VIN, I discovered Kia Safety Recall #SC336 (NHTSA Campaign 25V099), which identifies a piston oil ring defect known to cause excessive oil consumption and internal engine damage. I promptly brought my vehicle to the dealership specifically to address this recall. However, the dealership did not complete recall-related repairs. Instead, they determined—without sufficient justification—that my vehicle’s issues were not related to the recall, but to a "crush washer". My vehicle exhibits the exact symptoms outlined in the recall, including excessive oil consumption, rough engine operation, and stalling. The dealership then attempted to attribute the oil consumption to a crush washer on the oil drain plug, despite there being no visible signs of oil leakage under my vehicle at any time. This explanation does not reasonably account for the level of oil loss I have experienced or the internal engine condition. According to official recall documentation filed with the NHTSA, the defect involves improperly manufactured piston oil rings that can damage cylinder walls, leading to excessive oil consumption, abnormal engine noise, rough operation, and ultimately engine failure or stalling. The recall further warns that continued operation may result in engine seizure and loss of drive power. Independent automotive reports confirms that this defect has affected over 137,000 vehicles, including 2021 Kia Seltos models, and in many cases requires full engine replacement due to internal damage caused by faulty piston rings. Additionally, documented consumer complaints describe the same pattern I have experienced—excessive oil consumption with no external leaks, worsening engine performance, and dealerships attributing the issue elsewhere despite clear alignment with the recall defect.

AQ25001 · Kia 25V099 Piston Oil Ring Recall Effectiveness

Opened Aug 6, 2025 · Closed Dec 18, 2025

Status: closed (inferred from source dates) · Engine And Engine Cooling:engine:hard Parts Internal/mechanical

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.
