2021 KIA SELTOS Power Train Problems

My Seltos had a recall in 2021 (recall number SC209) because the piston oil rings were not property heated which can result in engine damage. The problem was supposedly repaired in 2021, yet in 2026 at 50,000 miles I am having piston notice problems and the engine light is constantly lit. The car has stalled on several occasions. I am being told that my vehicle with only 50,000 miles needs a brand new engine block and transmission. The recall was a safety recall to prevent the engine from stalling, risk of a crash and increased risk of fire. Although the issues with my vehicle are clearly as a result of the piston issue which were supposed to have been fixed they obviously were not and I am now experiencing all issues of the recall and bad engine. Kia of Round Rock is refusing to make this repair correctly and are...

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.

I See recalls on transmissions but i don't see one on mine and it is having the same problems as the other Seltos not sure way it's not on a recall list

Piston oil ring recall update complete in July 20 25. A month later key fob battery dies. Replaced key fob battery every other month since recall. September 20 25 had brakes and rotors changed at dealership since then anti-slip alert has triggered twice on dry roads. Light comes on then immediately goes off. Remote car starter stopped working in December. Dealership had no resolution for key fob issues and has not been able to replicate anti-slip issue. Dealership currently has vehicle to attempt to replicate issue and to look into the remote car starter issue. This is unsafe because the car automatically shutters and feels uncontrolled slip comes on also causes issues when key fob consistently dies every other month and get alert, letting me know that the key fob has died. And while the remote car starter is not a safety issue, it is all tied in with the...

THE CAR WAS MAKING A GRINDING SOUND, VIBRATES, SLOWS DOWN. GRINDING SOUND IS LIKE GRINDING GEARS OR A SNOWPLOW SCRAPING PAVEMENT. THE ENGINE WAS REPLACED IN APRIL BECAUSE OF RECALL. I ONLY HAVE 23765 MILES ON IT BUT ORIGINAL 5 YEAR WARRANTY EXPIRED ON 12/09/2025. THE SAME NOISE STARTED AGAIN ON 12/10/2025 AND IT WAS TOWED TO DEALER I BOUGHT FROM ON 12/10/25. The master warning light came on 12/10/25 incident and some text. There was traffic so unable to read it and light went off.

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...

My 2021 Kia Seltos is experiencing engine problems that match the piston-ring defect involved in Kia Recall SC336. I first took the vehicle to the dealership in August 2025 for excessive oil consumption and engine knocking. The dealer documented the engine was 1 quart low and stated the oil was “most likely being used internally getting past the piston rings.” However, they only performed the software update from SC336 and did not perform any internal engine inspection. Since that visit, the condition has significantly worsened. The vehicle is now consuming more oil than before, the knocking/ticking noises have become louder and more frequent, and fuel economy has declined. I am adding oil between changes to keep the engine from running dangerously low. There are no external leaks, so the oil is being burned internally, which is consistent with piston-ring failure. These symptoms are identical to other Seltos vehicles already included...

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.

We have a 2021 Kia Seltos. It was purchased 09/2023 as a certified pre-owned vehicle. Purchased from Putnam Chrysler Doge Jeep Kia in Putnam CT. It started using oil, about a quart a week. No oil spill on garage floor. Received notice of recall. We took it to the dealer for the recall in May of 2025. We were told it passed their inspection and the recall was entered as completed. Oil continued to run out. My wife could hear valves clicking and she new the oil was low. All this information was conveyed to the dealer and they had us bring it back in 6/2/2025. At that time an oil consumption test was performed. Die was added to the oil and was told to drive 1000 miles. Returned to dealer on 06/27/2025. Was told the test result showed no oil consumption. On [XXX] we were driving to market. The...

In April of this year I took my 2021 Kia seltos to Ourisman Kia of Fairfax (10601 US-50 Fairfax, VA 22030 United States). I took it there to get the piston oil ring recall taken care of, or at least looked at. They said it could take a couple of days so I left my car there. They had my car perked in a lot about a mile away from the dealership for a week or so and on April 19th they called me and stated that I could come pick up my car because it did not pass the recall. They stated that the recall was not available at this moment due to how many engines were back ordered. They stated it would take 3-6 months to get the engine in and do the actual recall. 4 months pass with no word from the dealership at all, so I...

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, the RPM fluctuated erratically before the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle was able to be restarted. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular failure. No warning lights were illuminated. The vehicle was taken to the dealer and was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 42,000.

Oil pressure light illuminated, extreme engine knocking, failed acceleration power and engine stalling while driving. Towed to dealership. Was told the vehicle "passed" the oil piston ring recall test and refusal of Kia to replace engine.

Awd coupler which impacting steering and the car shuts off while driving , all the issues accured after recall work was done .Updated the software and the car started to have problems.

Issue started to occur around 40,000 miles, when excellerating from a stop to about 30mph and when turning vehicle will feel as if it’s grinding or clunking in the front power train area. As miles increase on vehicle issue seems to happen more frequent.

Kia issued a recall for defective piston oil rings. The recall was performed on my 2021 Kia Seltos and showed that I needed an engine replacement. The day that the dealership tested my car Kia suspended the recall stating the test was inaccurate. When the recall test was reissued my car passed and was denied for a new engine. An oil consumption test was performed on my car and the results were that my Seltos goes through 2 quarts of oil every 1,000 miles. Kia will not do anything because I do not have records of 1 oil change that was done at my home. The recall stated the car is at risk for a fire hazard because oil could be seeping places it is not supposed to be. The car will also shut off while being driven if the oil gets below 2 quarts low.

Got to engine light error codes: P030100 and P030000. Happened 3 times: 1st time had loss of power and engine light flashed, could not accelerate, and vehicle shuttered. Took to world kia north San Antonio. They cleared the code. It ran fine for a while and same problem occurred. Took back to world Kia north. They had it quiet few weeks, finally got it back, they said they took it on a 60 mile road test no problems so gave it back. I drove it maybe less 2 hours after getting it back and the same problem happened loss power would not accelerate and engine light flashed but did not come on. Called Kia right when happened and brought it right back world Kia North and the service manager said to keep it running so they can see what going on, and they finally noticed the same thing. So it...

Related to the SC336 recall. My 2021 Kia seltos. I brought it in to the dealership before the recall. After the vehicle stalled on me. They did an oil consumption test on it and burns .5 quarts every 1000 miles still covered under warranty. Failed the piston ring noise test and now it’s passed the 2nd time they tried it. Still don’t have a rental car or my car. No leaks and burns oil I believe even more. Oil changes done on it routinely. Now they say it’s good to drive after they installed software. How does software prevent oil consumption?

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.

My car was checked for a recall regarding the vehicle burning oil and the piston rings. The fix for it was a new engine. When my car was checked for the recall, it was determined to be unaffected by the issue mentioned. However, I got an oil change approx. 1.5 months ago and at this point I have had to add oil to the car on two different occasions since due to the oil burning so quickly. The oil is also very, very dark. This indicates that the oil is burning significantly regardless of the recall status. I find myself checking the oil weekly due to the worry that it will be empty. The recommended mileage in between oil changes for my car is 7,500. I have not been able to wait that long since obtaining the car 2 years ago.

Transmission failed at 37k miles..noticed when the car was sluggish. Open the hood and the coolant reservoir was black. Kia replaced transmission but thinking about trading it in

Came to a stop at an intersection on a busy highway, went to accelerate and turn left when the transmission locked without warning. Vehicle would not shift into gear.

Transmission unreliable. While crossing a 4 lane highway the engine revved but would not engage.

The contact owns a 2021 Kia Seltos. The contact stated that while her daughter was driving 65-70 MPH on the highway, the engine was revving but the vehicle failed to respond as needed before shutting down. There were no warning lights illuminated. The vehicle was towed to the local dealer and was diagnosed with transmission failure. The vehicle was not repaired. The manufacturer was contacted, opened a case, but provided no additional assistance. The contact called the SAG Office and was referred to the NHTSA Hotline. The failure mileage was approximately 77,000.

I was at a stop light and when the light turned green the car i took my foot off the brake and placed it on the gas pedal, but the car wouldn't move. Almost like it shut down. I had to restart it to make it go. It ran but not the same.

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 contact owns a 2021 Kia Seltos. The contact stated while driving 60 MPH and attempting to accelerate, the vehicle briefly jerked before returning to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced.

My Transmission Temp light goes on when I am in slow traffic going on an uphill road. I need to pull over and let it cool down, This has happen in Mountains in Colorado , So it is cold outside. Both times i need to get a tow due to the fact there are no places to pull over on single lane road. it takes approx. 1 hour to cool down and i can only drive 100 yards before light comes back on. I have brought to Dealership twice in last several months and they tell me there is nothing they can do about it. This is a Major safety hazard.

Car cannot operate in reverse. Error code P060194. Forward gears are questionable.

After about a hour and a half of driving the car began to surge between 2,000 and 3,000 RPM. This has happen and few times but the last time the transmission lost high gear. The car had to be towed to the dealerships. The dealership is stating there is nothing wrong. I feel this is a safety issue.

esta quemando aceite de motor muy rapido y antes de tiempo. mientras se utiliza esta lento y cuando sube cuestas muy pesado tiene que hacer mucha fuerza.

While driving I noticed my Seltos felt like it was shifting hard. I then attempted to put it in reverse. There was NO reverse. I had to get bystanders to push me off the road. This is a safety risk because there were no warning signs that reverse would fail to engage. Kia states there is no recall, but several of same instances were found in forums. My car is scheduled at dealership next week. No rental, no recall, no warranty. I will have to pay out of pocket for something that has been known to fail. Supposedly an actuator of some sort. This repair will be costly and I feel it is a manufacturer responsibility. This is not normal wear and tear item. I bought this used, it was practically new. Now I know why someone traded it in. Kia should disclose their warranty limitations when they advertise. The...

2021 Kia Seltos possibly already had the recall work done in Florida before purchasing it used with only 18000 miles. It has stalled, once dying completely. Trouble gaining acceleration. Losing oil. Multiple oil consumption testing visits to dealership of 1000 miles each to continue showing Kia it loses over 1 quart per period. Now the glow relay engine and misfire engine codes are pulling which indicates engine damage after dealership has just last week replaced new spark plugs and oil change. It has been rough idle and ticking - knocking sound the entire time, which they denied the morning after purchase.

bought as certified pre-owned from a very large dealership in Clearwater. Driving off the lot there was a bad wobble and shake from corner to corner of vehichle. Took in day 2 of ownership to dealer to have them reinspect it and they let me drive away home too come back the next day after service manager started the car was completely safe to drive because there was no loaner car for me the day they promised me one ..five days in service and not hearing a word from the service department I stopped in and asked about my car. to have the tech say it ended needing and entire front CV axle and bearing because the bearing and axle had a lot of play in it! I've emailed multiple times and no one yet has called or emailed me back! bought on 9/02/2023 serviced 09/03/2023 to 09/15/2023 .. ....

My kia engine light came on during a drive and the vehicle would not shift gears (it would stay stuck on 1st). I manage to park and realize that it was not shifting to reverse either. I check the temperature and it was 4 lines below the middle which is normal. My car has proper maintenance and just came out of the 30,000 miles maintenance and is less than 3 years old.

The contact owns a 2021 Kia Seltos.

I was driving the car at a speed of approximate 30 mph. As I was slowing down for a traffic light, the car jerked backwards. The car braking system engaged without me touching the brake. When I took the car in for service, I was told they could not duplicate the issue. I took the car in after receiving the recall. I was assured all was well with the car, though I was having issues with the car stalling out at traffic lights. I took the car in for service and was told by the manager that they could not duplicate the problem. I became so frustrated with the car that I insisted the manager get in my car and drive it with me until the problem presented itself again. He did and the car stalled out on him 2x. They kept my car for two weeks and called me...

On our way to New York from Indiana when every light on the dash came on. The rpms shot up and down. Was able to coast off the highway IN Corsica IN. Car was towed to nearest kia dealership in Butler PA. The transmission went out on my car that has roughly 7100 miles on it. Dealership has ordered the transmission for replacement.

I drove my car less than a mile when the check engine light illuminated on the dashboard and issues with accelerating the vehicle started. The rpm needle moved when I pushed the gas but the car itself did not. Once the car was turned off it started but would not move or rev when the gas was pushed in any gear shift P, R, N, or drive. My car had just hit 17,880 miles when this issue occurred. This would have been a greater safety issue had I been on the road with other cars, there was no warning, or issues in the days previously with my 2021 KIA SELTOS. I’ve personally only driven it for about 8,000 miles as it was just recently purchased from a Hyundai-Kia dealership. The car was towed to Kia Service center and has been serviced for 32 days and counting. The manufacturer and dealership...

Brand new car on Dec 2020. Second time with a transmission problem. Was repaired at 6500 miles in June of this year. Dealer replaced it with a re-manufactured one. At 9300 miles I was driving in cruise control at about 70 miles per hour for a couple hours and while going up a long hill the transmission started slipping again and rpms went from 2000 to 4000 while it was trying to shift. The car began to shudder just like back it june so I knew the transmission was going. I slowed down and pulled off highway as the transmission continued to slip and had no power to go above 20 mph. I saw a parking lot up the hill to pull over at to be more safe off the highway and the rpms went up to 6000 and barely moved car then it caught and lurched the car forward...

THE CAR IS UNABLE TO SHIFT INTO DRIVE OR PARK. IT TAKES RELEASING THE SHIFT LOCK TO MAKE IT GET INTO REVERSE OR NEUTRAL AND A VERY SPECIFIC SEQUENCE TO ACCIDENTALLY GET IT INTO PARK. AFTER TRYING TO PARALLEL PARK INTO A SPOT, THE CAR BECAME STUCK IN REVERSE AND COULD NOT BE MANEUVERED. IT WAS ONLY ABLE TO ROLL DOWNHILL IN NEUTRAL OR REVERSE WITH POWER, BOTH OF WHICH WOULD HAVE LED TO A COLLISION. THE VEHICLE WAS STATIONARY ON THE CITY STREET AND BLOCKED TRAFFIC, ESPECIALLY PROBLEMATIC DURING THE SNOW STORM. I RECEIVED THE CAR BACK FROM THE DEALER 3 DAYS PRIOR FROM A TRANSMISSION REPLACEMENT AND SEEMS TO BE A PROBLEM IN THE SAME VEIN.

MY KIA SELTOS HAS TRANSMISSION PROBLEMS WITH ONLY A LITTLE OVER 6,000 MILES. IT NEEDS A NEW TRANSMISSION WHICH WON'T BE AVAILABLE UNTIL AT LEAST FEBRUARY 11TH

WHILE DRIVING ON THE HIGHWAY, THE VEHICLE FAILED TO ACCELERATE. ON A ROAD WHERE THE SPEED LIMIT WAS 60 MPH, THE VEHICLE STOPPED ACCELERATING AT 55 MPH SUDDENLY AND CAUSED DISRUPTION IN THE TRAFFIC UNTIL I COULD CRUISE TO THE SHOULDER IN NEUTRAL. IT WAS A SCARY SITUATION WHERE MULTIPLE ACCIDENTS WERE NARROWLY AVOIDED. THE VEHICLE WAS TOWED TO THE DEALERSHIP WHERE THE TRANSMISSION WAS IDENTIFIED TO HAVE A BROKEN TRANSMISSION WITH 3000 MILES ON IT.

AT 5,800 MILES, MY SELTOS SUDDENLY STOPPED ACCELERATING WHILE IN MOTION. RPMS SHOT UP TO 7 AND 8, AND THE CAR WOULD NOT GO ABOVE 35 MPH. THE ENGINE WAS GRINDING. I GOT THE CAR TO THE DEALERSHIP AND WAS TOLD THE TRANSMISSION NEEDS TO BE REPLACED. I WAS ALSO TOLD THERE IS NO TRANSMISSION IN THE COUNTRY SO ONE HAS BEEN ORDERED.
