My car has been recalled for faulty piston oil rings which can lead to engine fires. I took my car to the Kia dealership on 4/14/25. It is still there and the engine replacement still has not been approved. I was told by the dealership that my car did fail the vibration test. I was told by a Kia technician at another location that since the vibration test failed that is an automatic approval for a new engine per Recall Flow Chart. The only time it should go through Kia Techline for assistance is if it passed the test and needs additional investigation. NOW, Kia Corporate is stating I need to provide oil change receipts. THIS IS IRRELEVANT. If I drive that car off the lot with the current engine and have my engine cleaned out to their satisfaction and then a week later my engine catches fire because they refused to replace the engine, that's a lawsuit whether I live or die in that scenario. Oil change receipts and maintenance records should play no part in this. I did buy my car used, but all the original parts are still inside. There have been no modifications. The dealership can attest to this. Bottom line is the Kia manufacturer owes me a new engine because this is a safety issue. I am attaching a copy of the Flowchart that was sent to me by the Kia tech at another location. There is no reason that this should not have already been approved and ordered for my vehicle 2 weeks later. I want this done and I need your help, please! I do not feel safe driving a car around that could at any time burst into flames.

Bought the car used with around 30k miles on it from a dealership. Since then have only needed to get 2 oil changes done. Engine stalled while driving one day and noticed weird noises coming from under the hood. Had the car towed to the Kia dealership on Mon. 4/14. Car has been sitting at the dealership waiting on the manufacturer to approve replacement of the engine due to the recall. It should not take this long to get an approval for a safety issue. They're asking me for oil change documentation which I supplied them. Secondly, I shouldn't have even had to do that. This is a RECALL, not a warranty issue. A recall should get approved as soon as the engine failed the test. It seems like I'm having to jump through hoops to get this done and its not right.

I dropped off my 2021 Kia Soul at the dealership where I purchased it to address a nationwide recall, which states: “The piston oil ring(s) may have been incorrectly manufactured, potentially damaging the engine cylinder wall. This can lead to increased oil consumption, abnormal engine noises, engine seizure, and possible fire from oil leaking onto hot exhaust components. Loss of drive power and/or fire increases crash and injury risk.” My vehicle has shown multiple symptoms, including rough running, significant shaking, illuminated check engine and oil lights. On 01/02/23, I brought it in, but the dealership found no stored codes and took no action. On 04/20/23, a code for a cylinder 1 misfire was found, but because the issue wasn’t present at that moment, no repairs were made. On 10/05/23, spark plugs and fuel pump were replaced under warranty. No further issues occurred until 02/14/25, when the same symptoms returned. I was told I’d be charged for a diagnosis and they likely wouldn’t find anything, so I left without service. On 04/09/25, the symptoms reoccurred. I dropped off the vehicle on 04/10/25 and paid out-of-pocket for a rental until 04/14/25. On 04/14/25, after being told earlier that work couldn’t be done because the engine hadn’t cooled to 55°F, I was later told the recall was completed and the vehicle was safe—despite ongoing issues. I fear for my safety and the safety of others. I believe my vehicle needs an engine replacement and is unsafe to drive. The recall letter states inspection and software update should take 1–2 hours, and engine replacement 8+ hours. I request further diagnosis and repairs. Despite the vehicle continuing to show symptoms, I was dismissed. I am seeking accountability and proper resolution.

I have contacted Kia several times about this recall, the latest being today. I tried to schedule an appointment with Galeana Kia in Fort Myers, FL. The service departement told me there was no remedy for this recall. I referred the dealer to the Kia website. "Remedy 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 ARE EXPECTED TO BE MAILED APRIL 4, 2025. OWNERS MAY CONTACT KIA CUSTOMER SERVICE AT 800-333-4542. KIA'S NUMBER FOR THIS RECALL IS SC336." I then called Kia directly. They told me to contact the dealer. I told them I already had done so. The Kia rep told me that I had to wait for the dealer. I said I don't accept that because the KIA website lists the remedy. I eventually spoke to two supervisors. I was told that Kia does not own the dealership, so they can't force them to service the recall. Kia told me that if I went to the dealer now the dealer would bill me. I said that is unacceptable. In November 2024 I had an issue with my Kia that may be related to this recall. My vehicle stalled and I could not restart it. I had it towed to Galeana Kia. Turns out that the oil level was low in the engine. However, there was never any warning or warning light indication that the oil level was low. I was billed $315.96. I expect to receive a refund of that amount as this is related to the recall.

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.
