    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.

    The vehicle in question has been experiencing multiple ongoing mechanical issues, including engine stalling, frequent brake replacements, frequent oil changes, a camshaft issue, and intermittent horn functionality. These issues have raised serious safety concerns. Despite multiple repairs and maintenance attempts at the dealership, the problems persist, affecting both my safety and confidence in the vehicle. I have incurred substantial costs for repairs and rental cars while trying to address the issues. However, the problems remain unresolved, and I am not receiving adequate support. I contacted the corporate office for assistance, but the representative dismissed my concerns and stated I would need to provide maintenance receipts, even though the dealership had already confirmed they were unnecessary. This response was unhelpful and failed to address my safety concerns. Additionally, the service manager at the dealership has not offered satisfactory solutions or alternatives to resolve the ongoing issues. As a result, I am no longer comfortable continuing with the vehicle. Due to my financial situation and outstanding loan balance, I am requesting a goodwill replacement vehicle or a reasonable alternative that will allow me to maintain my current car payment without a substantial down payment or negatively impacting my credit. A replacement vehicle, ideally of the same make and model or comparable, would help me meet my financial obligations while addressing the unresolved safety and reliability concerns.

    Received a letter from KIA Headquarters stating a recall for piston oil rings and possibly engine failure. Inspection and software updates would take 1-2 hours, if replacing engine 8 or more hours. I made my appointment for today, arrived at Jone KIA in Bel Air, MD and am told that the letter is incorrect and I need to either leave my vehicle with them or reschedule. How many of the letters went out to owners and then we are told differently!

    I bought my ‘21 Kia Seltos in 2021. Within the first months it would stall when going uphill and in parking lots. I had a few mechanics look and they could not find any issues. So, I kept driving it. I drive 12 miles one way for work my wife drives it 1 mile both ways for work. Now [XXX] 47k miles it stalled out 2x the 2nd time it stalled it started to fill with fumes and smoke with my [XXX] - and [XXX] in the car. My kids and I have had a cough ever since. I called roadside; they first thought was the battery. So, the first guy tried to jump the battery, and nothing happened then he said he smelled something electrical burning. But could not locate. Then he said they will send a tow. Roadside then sent another guy to jump the battery. he smelled the same thing, but he found the source and said that the airbag sensors were burning. So, he disconnected the battery and called the tow. The car was towed at midnight to Grand Kia in Northglenn where the service rep was working on my car called me that day to tell me that the engine had seized, and he would submit a warranty claim to have it covered. I provided all service records to him including oil purchase receipts. A week later he calls and tells me they denied the warranty due to “lack of maintenance”. So, I call Kia customer care and speak with A lady who tells me it was denied due to “aftermarket parts” which there were none. She said once that flag was removed, she can escalate this case to a case Manager. Then I call Grand Kia back and talk to the service rep who says that flag is not there. Then I call back Kia and a different lady tells me the case was escalated and to expect a call and an email from the case manager. I call 4/10/2025 and am being told there is not an escalation on the case. I get transferred to a supervisor line and after waiting on hold I had to leave a voicemail, still no returned call. All this while there is a safety recall out that causes my exact issue and the engine needs replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

    What component or system failed or malfunctioned, and is it available for inspection upon request? The engine system appears to be malfunctioning. Specifically, there are signs of a potential head gasket failure, valve cover gasket leak, or internal engine damage due to oil leakage and excessive white smoke from the exhaust. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The white smoke obstructs rear visibility, which poses a danger to other drivers. The unpredictable engine revving in idle or park also raises concern for unintended acceleration or engine failure, which could cause a crash, especially in congested or residential areas. In addition, the oil leak poses a fire risk and environmental hazard. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the symptoms have been observed and documented consistently. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has not been formally inspected by the manufacturer, police, or insurance representatives at this time, but I am open to having it evaluated by any relevant party as needed. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lights initially. The symptoms began with mild engine revving at idle and a burning oil smell. The white smoke and oil leakage became noticeable shortly after. The issues have progressively worsened over time and now the check engine light is on.
