I purchased this new 2026 Kia Seltos with approximately 32 miles. The vehicle now has fewer than 600 miles and has experienced two incidents of sudden, intermittent, complete loss of accelerator response. During one incident in highway traffic, the vehicle unexpectedly began decelerating and pressing the accelerator pedal produced no acceleration or meaningful propulsion. I could not maintain speed or accelerate to move out of surrounding traffic. The vehicle became unable to move normally until it was turned off and restarted. An oil-pressure warning light illuminated during the failure. There was no meaningful warning before the loss of acceleration. After the first incident, an authorized Kia dealer found diagnostic code U200300 only in the vehicle’s history. The dealer attributed the condition to a loose right battery cable, repaired or tightened the connection, and returned the vehicle as fixed. The same loss-of-acceleration condition occurred again after that repair. On July 13, 2026, an authorized Kia dealership technician personally reproduced the failure during a 30-mile test drive. The technician documented that the vehicle felt as though it died during acceleration and that pressing the accelerator would not make the vehicle go anywhere. No diagnostic trouble codes were generated or found during this dealer-confirmed failure. The dealer and Kia Techline inspected the vehicle. The dealer documented proper oil level, no obstruction in the air filter or throttle body, no visible leaks, approximately 50 psi of oil pressure at idle, and no visible corrosion or damaged connector pins. The diagnostic records provided to me end while Kia Techline was still asking about the oil-pressure sensor. I have not been provided with a confirmed root cause or documentation showing what specific repair permanently corrected the loss of propulsion. The failure creates a serious crash risk because the vehicle can suddenly lose all useful acceleration in highway traffic, l

After getting recall work done last year regarding SC336 my sensor went off and now my car needs a new engine due to defective heat-treated Piston oil rings causing Catastrophic failure. Kia is declining responsibly because of lack of enough oil changes. They have not proved this failure was from neglect.
NHTSA complaint #11753056 — an unverified report by a vehicle owner.
Since November 2025, this vehicle has experienced repeated loss of power, severe shaking during acceleration, jerking between gear shifts, abnormal humming/grinding noises, and multiple check engine light events. The condition is most noticeable between approximately 40-70 mph and has repeatedly occurred while driving on highways. On multiple occasions, the vehicle struggled to accelerate properly and would not respond normally to throttle input. During one occurrence, the vehicle had difficulty accelerating beyond approximately 55 mph while on the expressway. The shaking became severe enough that I feared mechanical failure could occur while driving. I was forced to pull off to the shoulder of the highway because I no longer felt it was safe. The inability to maintain speed and accelerate normally created a safety risk for both myself and surrounding traffic. The vehicle has been returned to the dealership six times for the same recurring issue. Repairs have included replacement of the ECU, catalytic converter, ignition components, fuel injectors, and other engine related components. Despite these repairs, the problem continues to return. The condition has been repoduced and documented by the dealership, and a manufacturer field technician was involved in the most recent diagnosis process. Most recently, after the vehicle was inspected and believed to be repaired, the check engine light illuminated again while the service manager was moving my vehicle to be washed inside of their garage, as I waited (today, June 11th 2026). The recurring loss of power, repeated check engine light events, and inability to permanently correct the defect raise significant safety concerns while operating the vehicle. I have all documentation in my notes, as well as the dealership repair documents.

My 2022 Kia Seltos out of nowhere started smoking, losing power, total control and braking. There were no lights on the dashboard warning of any kind complete stall than a little bit of power hesitation stall no brakes. I managed to coast it into a parking space at a hotel with it smoking so bad I couldn’t see. It then burst into flames and golfing the entire Engine bay and melting the front of the car about 90 seconds after I got out of the car all of the symptoms here are completely aligned with the recall on this vehicle and the soul. In fact, my son soul had all the same issues except the fire and Kia refused to replace the Engine claiming that his lack of a recent oil change caused the problem that we all see reported here this vehicle was not in the recall VIN group but failed catastrophically just as described in the recall
NHTSA complaint #11740429 — an unverified report by a vehicle owner.
The engine seems to be failing/affected. The vehicle is currently available for inspection at Huffines Kia in [XXX] where it has been since Saturday, March 14, 2026 and they have yet to perform the SC336 Safety Recall while trying to charge a diagnostic fee for a multipoint inspection that I did not ask for. The vehicle would not start which now I know is due to total oil consumption, which appears to be a precursor to the recall. Having a vehicle that can catastrophically fail or stall without warning due to defective piston rings creates extreme risk of a crash or fire while my family is inside. The service department at Huffines Kia Mckinney confirmed to Kia Corporate on Wednesday, March 18, 2026 that the vehicle was completely depleted of oil. However, they have not officially confirmed the recall failure because they have not done the recall test. They told corporate that they haven't done the recall because I did not have oil in my car. They have had my car since Saturday, but have not topped it off with oil since it has been there for several business days. I have also opened a formal case with Kia Corporate (Case #XXX) due to the dealer not providing the free safety remedy required by law. There was no oil pressure warning light prior to the failure, however, when trying to start my car and it wouldn't start, the oil and engine light came on. A tow truck came to tow to the dealer. The tow driver was able to start my car using a jumper box. The dealership says my car ran fine and no oil or engine light was on. However, if they ran my car knowing it was depleted of oil, they have potentially further damaged my engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle is included in NHTSA Recall 25V099 / Kia SC336 for defective piston oil rings. The vehicle has experienced stalling, loss of power, knocking noises, and oil consumption. The engine behavior is unsafe and consistent with recall-related engine damage. Kia closed my case based on a dealer’s subjective noise judgment, but no mechanical engine testing (oil consumption, compression, or cylinder inspection) was performed. The recall remains incomplete and the vehicle continues to present a stalling and fire risk.

Can smell gas fumes in and around car. Afraid to drive. Took to dealer. Fuel pump and associated gaskets fittings needed to be replaced. Not cover under 10 yr, 100K warranty even though the vehicle only has 83K miles. Just to right.
NHTSA complaint #11705286 — an unverified report by a vehicle owner.
I am writing regarding my vehicle, a 2021 Kia Seltos LX - VIN Number [XXX] , which is subject to a recall NHTSA #25V099, Manufacturer Recall Number SC336. I was informed of the recall April 2025 and have since experienced engine stalling while driving on the highway with my young children with me, abnormal engine noise, complete oil loss and eventually complete engine failure. Unfortunately, this defect caused my vehicle to become unsafe and completely inoperable for the last 8 weeks. Kia said "We have completed the SC336 Piston Oil Ring recall, and your vehicle did pass. This means that the failure of the engine is not covered within the scope of that recall. This vehicle also does not have Kia warranty coverage active now due to age and miles. At this stage, Metro Kia does not have any further recourse for warranty coverage." My kia was stalling on the highway, complete oil loss where it was bone dry which led to engine failure. How did the vehicle "PASS" when EVERYTHING from the description of the recall is EXACTLY what happened to me? This is absolutely wild that Kia is refusing to do anything about this vehicle. It is a 2021, with 65,000 miles on it. The repairs are over 13K and I am being told I would get nothing for the car if I traded it in because it is worth nothing. Because of this situation, I have experienced a complete loss of transportation and have been relying on other methods of transportation and emptying my bank account for numerous towing visits to and from the dealership. Kia has not fixed the recall and instead quoted me over $13,000 to repair the car. I have enclosed copies of relevant documents, including the recall notice, service records, and any related correspondence. I messaged the BBB and attached Kia's response to that, as well as an email with the service advisor at Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought this vehicle brand new in 2021. I noticed at the beginning that when I accelerated that the car would delay in acceleration. This would happen sporadically. Now it is happening all the time and has almost caused me to get into several accidents because of the delay in acceleration. This is a major safety risk. I've had the car inspected at Kia Dealers and they just say yeah, we hear that a lot with this model but there is no recall. There are no warning lamps or messages.

After being stopped while driving when the car turns off, when re-starting sometimes the car will turn off, I have to put my car into park in the middle of the street to restart the engine. Other times, it will start alerting me to "push the start button" as if my car isn't on already. This causes me to come to a complete stop in the middle of the intersections and puts me at risk.

In January my husband was driving the Kia and it broke down. We took it to the mechanic and they said it was completely out of oil. Spent $5,000 on getting it fixed in a couple weeks later find out there's a recall. Took the Kia to the dealership in Ocala. They and told us there was nothing wrong with it and that they fixed it. It also makes noises when you turn the car on. to this day we still have to put oil in it almost every day. And it still makes a weird farting noise when you turn it on. I even asked mechanic in Ocala if it made that noise. He looked at me like a was stupid haha. And then I asked him what would happen if we still had to keep putting oil in it. He said we shouldn't have to.

I pulled off the main road into the Walmart parking lot. When I did, the vehicle shut off, no power and steering was very hard. I was able to steer into a space and safely park. Vehicle was towed to Victory Kia in Victoria. Service dept said there was no oil at at all in the vehicle. Vehicle was recently taken in for the Kia engine recall about 3 months ago. Was told I needed an software update and oil change to remedy the problem. I got a full synthetic oil change. The vehicle burned all the oil off. No low oil or oil warning light ever came on. Now, Kia wants me to pay for another oil change and diagnostic and drive the vehicle for 1000 miles to see the outcome. Which, if/when the motor dies out again,then I'll be stranded again, hopefully not on a freeway this time. It's crazy I have to be a guinea pig for Kia to see if when the car dies out again, hopefully it don't catch fire this time when all the oil burns out like it did last time

My vehicle is currently in the shop at the local Kia dealership. Over the past week my vehicle has randomly stalled several times. The engine sounded like it was sputtering, and just not accelerating properly. The car would stall at low speeds while turning corners or pulling into a parking spot. I do not have the diagnosis as of yet but believe my vehicle should be considered one of the recalled engines due to its date manufactured and the current issues that are occurring. Noticed stalling at speeds 45mph or less. It's very frustrating with a vehicle having 82,000 miles on it. All mandatory maintenance has been done at correct intervals and now this. It needs to be reported.

My 2021 Kia Seltos has an active safety recall related to the engine (Recall #SC336). The dealership (Darling's Kia, Formerly Van Syckle Kia in Bangor, ME) scheduled a repair but canceled it due to needing a "software update." I was told there is no timeline for completion and that no loaner or alternative vehicle would be provided. I am concerned for my safety and transportation, as the recall affects piston oil rings that can cause engine damage, stalling, or fire. Kia consumer affairs acknowledged the delay but provided no resolution or support. This recall has been open for months and is still unresolved.

While driving at low speeds, the vehicle would stall, no engine lights or warnings would appear on the dashboard. After turning it off and back on, it would run but stall again shortly later. An unfamiliar foul odor appeared from the dipstick as I checked the oil. Car only has 60k miles on it. Engine is throwing codes for cylinder 1, cylinder 2 and crankshaft.

This happens everyday while I’m driving. The vehicle hesitates and grinds when you try to accelerate and prevents you from going forward. It pulls the car back in yanking motion. Which is extremely dangerous.

The vehicle was sputtering and then shut off and would not start. I called KIA and had it towed to Dealership. They called several days later stating there was nothing wrong with the vehicle. Then several weeks later getting on the turnpike it sputter and shut off. I was able to get it started again and repeated the same sputter and shutting off an additonal 2 times on the turnpike. I was able to get the vehicle home to my drive way. The tow truck came and could not get it to start. He towed it back to the dealership. This time they replaced the fuel injector. The mechanic advised KIA that this issued caused scoring on the cylinders. KIA authorized replacing the fuel injector. KIA claimed scoring on the cylinders is normal. You don't have to be a mechanic to know this is. not normal and over time will lead to engine failure. KIA will not replace the engine. My case # is 15929784

I've owned this car since it was new. I've been disappointed with the transmission. At low speeds, it will hesitate and shudder. This is especially true if I'm making a turn. This has been a consistent problem. Secondly, twice my transmission has overheated. The first time we were in a Halloween event during the Pandemic 2020. It was a drive-through event that was stop-and-go. The warning light came on with the gauge showing one bar over the limit. As luck would have it, the traffic started to move towards the end and it lowered the bar to just under the overheating bar. The second time this happened it was much more serious. I had four people in the car. We had just left a restaurant and were heading towards the freeway. Unfortunately, we got stuck on a hill in Hollywood Bowl traffic. We were stuck there long enough that my car shut down on the hill. We were blocking traffic and my wife got out to direct traffic around us. I tried to put the car in neutral and coast towards an open curbside parking space. It wouldn't budge. We spent what felt like an eternity blocking traffic. It was probably 4-5 minutes where we were unable to start or roll backward.
