I have had this car for about two years. A year ago I was having issues with the car stalling, and the check engine light. I took the car in and it was "fixed". I have to get oil changes very frequently, and still have to top up my oil in between changes. I made my appointment for this current recall. While waiting for the recall, my check engine light came on. My car displays all of the symptoms of the issues in the recall. I took my car in for the appointment on April 28th. They told me they would update me the following day after the testing. Kia called to inform me that the next day that the recall is on "halt" and they have no further information. My car has been sitting at the dealership since 4/28 with no further information. They have not called to update again, I've had to call them. They also have not checked into the check engine light. My car is under warranty so I don't understand how they haven't checked into that regardless of the recall. When asked about a loaner car they state they don't have any, and provide no assistance with getting one.

Regarding: Manufacturer Recall NumberSC336 NHTSA Recall Number25V099 Car: 2021 Kia Seltos EX - I had an appointment to repair this recall with Kia for 5/6 which they cancelled on 4/30. The Service Dept told me they weren't moving forward with correcting this recall, even though it is still listed as active. - I called Kia Customer Service on 4/30 and they confirmed 1)this is still an active recall and 2)there was new communication being sent to service centers on either 4/30 or 5/1 and to reschedule on 5/1. - On 5/1 I called to make an appointment and was told I could not. I called Kia Customer Service and was told that the information from the prior day was wrong. Kia confirms this is an active recall but they are not currently correcting it. They cannot tell me when they may be able to, but more importantly they did not have a way for the customer to find out if they are correcting except to call everyday and ask. They don't know if they will call, email, send a letter to advise about the delay and next steps. - The safety risk increases the chance of fire or accident. I understand there may be issues on how to fix, but all I was asking is either a timeframe or for Kia to advise when I can get this fixed and they would not provide either. I just want to know when the car that I paid for will be safe to drive again. - I did leave a message with a supervisor at Kia Customer Service as that was my only option and was told I could get an answer in 48 hours. I have not received that answer.

Dealership called me to inform me they could not complete my recall due to a memo sent by the manufacturer today. I was told to pick up my vehicle despite the incomplete recall with its safety risks. I called the manufacturer to get further information as I was not comfortable picking up my vehicle and driving it if according to the recall campaign “ ENGINE DAMAGE CAN CAUSE A VEHICLE STALL OR FIRE, INCREASING THE RISK OF A CRASH OR INJURY.” Manufacturer and dealership spoke on the phone; manufacturer told me to just pick up my vehicle until the dealerships can resume completing the recall in the future. I inquired about safety risks and the manufacturer told me “it’s most likely okay”. Safety concerns I brought up were dismissed.

I received a recall letter for my Kia 2021 Seltos EX 2.0 dated 4-4-25 for piston oil ring and engine inspection. I checked my car in with a local Kia dealership on Thursday the 24th. Approximately, thirty hours later I received a call it passed inspection. On Friday I picked my car up and did my normal Friday laundry and went home. I’m talking about for the laundromat and my home maybe a total of three miles, if that, within the dealership. The car ran perfect as usual. On [XXX] I drove 15 miles to shop and dine out. On the way back my check engine light came on (solid) and the power was extremely poor and reduced. Didn’t think I was going to make it. I had planned on doing another stop before getting home, but had to pass and try to make it. My car ran perfect before this inspection and I did not want this inspection for fear something would go wrong, but felt I had no choice. So, I’m waiting to hear Kia say the inspection had nothing to do with your check engine issues. I understand Kia started its investigation in February 2025. I’m wondering if some of these investigations were done remotely by Kia? Strange during February I experienced a couple of glitches going on with my car while I was driving. First, the car did not recognize my seat belt was fastened in the driver seat. The fastened your seat belt icon flashed and that annoying ding noise went on for the duration of my drive, approximately thirty minutes or so until I got home. After it sat overnight it seemed to reset itself. Then, during this same month, I was taking care of my normal morning errands as usual. My start engine light flashed while driving, and that annoying ding noise again. The power reduced like my car was going to cut off getting through a green light. That straightened out immediately and there were no more issues with my car. Until this recent inspection. Do anyone know if Kia remotely inspected cars for the piston oil ring issue? Strange how after these glitches I received the recall letter. I’m just coming to lea

Would drive my car and the check engine light would come on and the car would basically lose power and could barely move it to safety!!! Called and wouldn’t be able to get in for a couple months. Happened again, got to the side of a road. Meantime, get the recall on the piston oil rings; determined the engine lights are related to this recall. Car into the Dealership and it failed inspections. Determined damage and new engine is ordered. NO ETA on new engine; just drive my car as is! What assurance is there my car won’t stall, crash or have a fire all while waiting for a new engine. Lost all faith in Kia with parts incorrectly manufactured. I feel this is jeopardizing the safety of myself and other KIA Seltos drivers and basically anyone around me if there is an issue/crash.

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.
