2021 Kia Seltos complaints

To Whom It May Concern, I am filing a formal safety complaint regarding my 2021 Kia Seltos (VIN: [XXX]). My vehicle was previously serviced by Kia in connection with a recall in 2021. Despite the recall-related repair being completed, the issue has not been resolved. My check engine light continues to illuminate, and my vehicle has repeatedly stalled and completely shut off while stopped at red lights and intersections. This creates a serious safety hazard. When a vehicle unexpectedly loses power in traffic, it places the driver, passengers, and surrounding motorists at risk of an accident, injury, or worse. I understand that there have been reports, recalls, investigations, and consumer complaints involving certain Kia vehicles with engine-related issues, including concerns regarding piston oil rings, excessive oil consumption, engine damage, and engine failure. While I am not a mechanic and cannot state with certainty that this is the cause of my vehicle’s problems, I believe my vehicle may be experiencing a similar issue based on the symptoms it is displaying. My concern is that the ongoing engine warning light and repeated stalling events may be related to an underlying engine defect that was either not corrected by the previous recall repair or has developed despite that repair. Given the known concerns surrounding certain Kia engines and piston oil ring-related issues, I believe my vehicle should be thoroughly reviewed to determine whether it qualifies for coverage unde

Usually the car would be taken to a shop for an oil change and I did it myself last time and realized the oil was pretty low. I checked over the weekend and noticed the dip stick marked the oil as 2/3 full after waiting 10 minutes for it to cool down a bit. This is alarming because when I filled the oil it was close to the max level.

The infotainment head unit display system suffers from persistent firmware connectivity defects that cause severe system lag, complete screen freezing, and constant Bluetooth/phone disconnections. This directly compromises vehicle safety by rendering mandatory hands-free voice operations completely inoperable while driving, creating an intense electronic driver distraction. Furthermore, the system instability occasionally causes the central display screen to lag or fail to transition, impacting the reliability of the backup camera display. The manufacturer (Kia America) does not provide a functional consumer download path to patch the firmware build, and the local franchised dealer (Arapahoe Kia) explicitly refuses to service or update the component, leaving the vehicle with an ongoing electronic defect.

The car is available for inspection upon request. Safety was put at risk due to the cars potential to break down, or catch fire, due to high volumes of oil consumption and leakage from the piston rings. This was part of a recall campaign (#SC336 PISTON OIL RING), where we had two authorized Kia dealers inspect and claim the car "passed" their test. Recently, we had a catastrophic engine failure due to the piston rings, where we feel the fix was insufficient given the failure point (piston rings). There were no warnings or symptoms prior to failure, when driving at a low speed the car stalled and the oil pressure warning light came on briefly. After that, we parked the car immediately and had it towed for inspection. Our concern is the fix was allegedly implemented in July 2025, but there is no note in our maintenance record that the fix was even implemented.

The contact owns a 2021 Kia Seltos. The contact stated that days after the engine oil was changed the check engine warning light had remained illuminated. The vehicle as taken to the local auto service center who replaced the replaced the crank shaft sensor and camshaft sensor but the failure continued to occur. The cause of the failure was not determine. The manufacturer was notified of the failure but no assistance was offered. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 21V259000(ENGINE). The contact indicated that the vehicle had experienced that same failure listed in the recall. The failure mileage was 120,000.

Kia Dealership did nothing with engine recall in 2025 they said nothing was wrong despite the oil consumption and engine noise that could be heard without using any tools, and then in March they would not honor the 10 year 100,000 mile warranty when both VVT solenoids failed, we had to replace them ourselves. It's a good thing my boyfriend is a mechanic!!!

While in the middle of driving on the highway, the vehicle has powered off then back on. The vehicle “slips” when revving up.

The contact owns a 2021 Kia Seltos. The contact stated while driving at an undisclosed speed, the contact noticed an unusual knocking sound and the engine seized. In addition, several warning lights were illuminated. The contact stated that while attempting to start the vehicle, the vehicle started. The contact inspected the vehicle and noticed that the oil was three quarts low. The contact stated that the vehicle was scheduled for a service appointment for an oil change the following week. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

This vehicle burns oil excessively. From everything I've seen says this should be under recall but the Kia dealership tells me it's not because it's over 60,000 miles and I'm the second owner. They offered to do a oil consumption test for $900. I've already read complaints about this engine locking up and people being seriously injured. I have to put oil in it every thousand miles or so. For a newer vehicle this is unacceptable and Kia should be taking care of this. This is absolutely going to get someone killed when their engine seizes. The transmission on this vehicle also has issues that have complaints littered through the message boards. KIA knows it's going to fail and get someone killed as well. They dont care as long as they get your money. Unacceptable.

The engine catastrophically failed on an 45 mph road. There was no warning leading up to this incident at any time previously. The engine lost all power and the car shut off on this road. My husband was able to pull it over and tow it into a mechanic. The mechanic said the oil was disappearing somewhere without any residue, and without triggering any warning light of any kind. In essence the oil is not low enough to trigger the light but it is also escaping somewhere. The mechanic said it seemed like the engine had a fault in it. Because of the open recall on the piston rings, we had it towed to the dealership who then claimed this problem has nothing to do with the faulty piston rings. Instead they said there is a rod knock. The car is currently at Doug Smith Kia in Lindon, Utah and can be inspected there.

Engine seized and was smoking. No warning lights on dash until engine siezed and then it was ESC light that came on. Engine started smoking when seized. Checked oil and there was none however we had just had the vehicle in for a state safety inspection 2 weeks prior to this happening. Have had regular oil changes thru dealership and car was scheduled for oil change prior to this incident happening. This year and model of car already has a recall for piston rings overheating and burning oil which causes Engine failure and fire. Warranty claim was denied due to no oil in Engine and Kia doesn't include oil consumption with their warranty. Car is currently at First Team Kia Dealership in Suffolk, VA

My car stalls in the middle of traffic. I took the vechile for diagnostics with a mechanic and was informed my piston rings were bad. Currently a recall in progress. I take my car in for recall of faulty piston oil rings that can cause engine damage, stalling, or fire. The dealers inspect and stated it was not the right sound. I take it back to mechanic and was informed I should contact you all Cause they are refusing to do the right diagnostic.

My vehicle recently idled roughly and shut off at low speeds and while stopped at intersections on my way to work. I brought it to an authorized Kia dealership the very next day. After researching my VIN, I discovered Kia Safety Recall #SC336 (NHTSA Campaign 25V099), which identifies a piston oil ring defect known to cause excessive oil consumption and internal engine damage. I promptly brought my vehicle to the dealership specifically to address this recall. However, the dealership did not complete recall-related repairs. Instead, they determined—without sufficient justification—that my vehicle’s issues were not related to the recall, but to a "crush washer". My vehicle exhibits the exact symptoms outlined in the recall, including excessive oil consumption, rough engine operation, and stalling. The dealership then attempted to attribute the oil consumption to a crush washer on the oil drain plug, despite there being no visible signs of oil leakage under my vehicle at any time. This explanation does not reasonably account for the level of oil loss I have experienced or the internal engine condition. According to official recall documentation filed with the NHTSA, the defect involves improperly manufactured piston oil rings that can damage cylinder walls, leading to excessive oil consumption, abnormal engine noise, rough operation, and ultimately engine failure or stalling. The recall further warns that continued operation may result in engine seizure and loss of drive power.

I own a 2021 Kia Seltos with a 2.0L 4-cylinder engine (146 hp) and approximately 38,967 miles at the time of failure. On April 21, 2026, the vehicle began rattling during acceleration and stalling at stops with no warning lights of any kind. On April 22, 2026, my partner and I were driving on the highway when the rattling intensified and the vehicle lost the ability to accelerate properly, requiring my partner to press hard on the gas just to keep up with highway traffic. He safely exited the highway and shortly after turning off the main road the vehicle stalled completely on a residential street and could not be restarted. My partner opened the hood, at which point white smoke was visible and there was a strong burning smell. The vehicle was towed from that location to an authorized Kia dealership. Upon arrival, the service manager noted a burning smell from the starter motor. The engine produced no cranking sound when the key was turned. On April 24, 2026, the dealership confirmed the engine is seized and submitted the case to Kia corporate. The vehicle was properly maintained with oil changes every 3,500–4,500 miles. A full inspection just 3,587 miles prior identified no engine issues. No warning lights appeared at any point before or during the failure. This failure matches the defect described in NHTSA Campaigns 21V259 and 25V099, both citing improperly heat-treated piston oil rings in 2021 Kia Seltos vehicles equipped with the 2.0L engine causing cylinder wall damage,

*The end of March, my car suddenly started making an awful grinding noise, jerking, slowing down even with foot on excellerator. Towed to nearest Lia in Leesburg. Couldn't find anything wrong. Happened two more times didn't take in. Next time it happened in April towed in. *My engine was replaced in April of 2025. *Was fine until 12/10/25. Same grinding, etc. Was worse than before. Found out my 5 yr. warranty ended on 12/09/2025. Had it towed to Ocala Kia where I bought car. Updated software to what it was before replaced engine. Found out engine only had warranty for 1 year. That has expired. I thought I had purchased 5 year extended warranty when I bought out lease but I don't. So I don't know what I paid for. I do not feel confident that it is fixed nor do I trust dealer. *I have asked both dealerships to give me a written explanation on what they have tested for and dates and serial # on parts. I was told that info was only for dealer and won't let me know. I want to know if any damage to parts that were source of grinding. I have all or most of paperwork for service. I am taking car to another reputable auto repair to check it over for so I can decide to get rid of it. *I want to make sure it is on record that I have let you know that fixes haven't worked. Problem is sporadic and unpredictable. I cannot find out what they have checked. This was my last car. I like it but no longer trust it. [XXX] [XXX] CP [XXX] . I have sent in complaint before but never heard back. INFO

This is supplemental information for my existing Complaint #XXX – 2021 Kia Seltos SC336 / 25V-099. Key facts and timeline: Purchased as Certified Pre-Owned on August 17, 2025 from Rairdon Kia of Burlington. Safety Recall SC336 / 25V-099 performed June 24, 2025 (mileage 61,378). January 15, 2026 oil change performed at Smith Kia of Bellingham (R.O. XXX). April 2, 2026: Sudden severe loss of power at highway speeds on I-5 North with flashing check-engine light. Vehicle returned to Smith Kia (R.O. 57763, mileage 71,703). Service Advisor Sebastian Goulding confirmed the engine was 3 quarts low on oil and provided a hard copy of the active DTCs P132700 (Piston Noise Detection) and XXX (System Too Lean – Bank 1). Smith Kia performed only an oil change and cleared the fault codes. Please see the attached detailed PDF timeline and supporting documents (fault code history showing P132700 and P017100 still listed in “History” state, Smith Kia records, Rairdon Kia $244 improper diagnostic invoice, and NHTSA confirmation).

This has happened 3 other times. It just stalls out when stopped. Not to do its SMART thing but it clunks-like and turns completely off. Its a bit scarey. And now heat issues just like the last 2 summers. It has issues!

On April 7, 2026, the vehicle experienced a 'quiet fade out' stall while in motion, resulting in a total loss of motive power. The dealership (DCH Kia of Temecula) confirmed cylinder scoring and referenced Techline Case 26022952. This failure is identical to the conditions described in the NHTSA Campaign 25V-099. The dealership is currently refusing to classify the repair as a Campaign Repair, which would include the mandated Lifetime Engine Warratny, and is instead attempting to process it as a discretionary 'Goodwill' repair to avoid federal safety requirements.

Vehicle: 2021 Kia Seltos VIN: [XXX] Mileage: 71,728 Recall: NHTSA 25V-099 / Kia SC336 (piston oil rings) – Subsequent Repair Action SC336YZ On [XXX], while driving at highway speeds during a trip from Everett to Bellingham WA, the vehicle suddenly lost power, the check-engine light came on, and it set DTCs P132700 (Piston Noise Detection) and P017100 (System Too Lean – Bank 1). The engine was documented 3 quarts low on oil. This is the exact failure mode described in the recall: defective piston oil rings causing oil consumption, engine damage, and loss of motive power. The nearest dealer (Smith Kia of Bellingham) performed only an oil change and cleared the codes, then declared the car “good to go.” The vehicle was then driven 20 miles to Rairdon Kia of Burlington, WA (the original selling Certified Pre-Owned dealer), where it is now located. Rairdon Kia states they cannot perform the full engine long-block replacement under SRA SC336YZ because the codes are no longer active. Kia USA Customer Care (Case #[XXX]) called today and stated they are “taking the side of Smith Kia”. They suggested getting another dealer’s opinion. We are now being told we must drive the vehicle until the code re-triggers. My wife refuses to do so. She is extremely upset and afraid of getting stuck on the side of the road or causing an accident due to sudden loss of power at highway speeds — exactly what happened on [XXX]. This situation is now causing significant stress and disruption in our persona

I have a Kia Seltos 2021 AWD EX 24,700 mi. that was recalled and new engine put in on April 12th 2025 to fix grinding noise that occurred 4 times the end of March starting on the 17th 2025. On Dec. 12th 2025 Grinding noise started again. Couldn't find anything wrong and told them to try harder. Said needed software update back to what it was before engine put in. My problem: I don't have the 5 year extended warranty that I thought I had. Never got papers about warranty of new engine which I don't think it is. No papers saying if they ever checked to see if parts affected by grinding had shown wear. Neither dealer where it was serviced had done this to my knowledge and won't give written proof. I never had a copy of any of the paper work I signed in front of me the 3 ½ hours in office. He would go over and tell me to initial or sign. Then didn't want to give me a paper copy but put on zip drive. I insisted on paper and about a ½ hour late he came with 28 pages of mostly size 6 font. I just wanted out. They have known this car has had issues since the day I bought it. I have called customer service dealer and corporate. According to paperwork Im not allowed to ask for a jury trial, go to arbitration or join a class action suit nor get reimbursed for repairs caused by defects. I went to Sr. vs. Crime and they tried to call to get paperwork and they didn't return calls. What options do I have left as the ods of needing repairs seem obvious. My car is worth nothing - bad reputatio

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power with the check engine and traction control warning lights illuminated. The vehicle was able to restart; however, the failure recurred. The vehicle was initially taken to an independent mechanic and then towed to the dealer. The dealer diagnosed the vehicle and retrieved DTC: B001400 and P00A0. The contact was informed that the piston flap and cylinder #1 had failed, and that the engine needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 46,803.

On April 4th 2025 I received a letter concerning NHTSA Recall 25V099 and was asked to have dealership run diagnostics. On April 30th dealership says "YES" engine needs to be replaced. Two days later dealership calls me and says new software has arrived and they need to run diagnostics for recall again, this time on May 16th 2025 car passes. NOW, almost one year later and after warranty has expired, the car has a DTC P1327 which is noted in the recall letter and the car will NOT start. Had it towed to nearest dealer and they say since the original dealer "Passed" the recall, I have to pay to get car looked at again. It is obvious to me their original diagnosis missed something and now I just want my vehicle back, but it won't run because of the P1327 DTC and of course the dealership where car is now says since I did not buy it there, nothing they can do? KIA service is TERRIBLE.

Excessive oil consumption Engine damage or failure Ticking noise from the engine Loss of power when driving Rough idle, shaking the car is not able to be used, for safe.

While driving engine shut off and car will not start. Garage states engine is seized up. It is same engine that Kia recalled

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 r

The contact owns a 2021 Kia Seltos. The contact stated that while driving at 50 MPH, there was white smoke coming from the engine, before the engine caught on fire. After the failure, several unknown warning lights illuminated. The contact was able to pull over safely. The fire was extinguished independently. There were no reported injuries. The contact stated that the failure was related to NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed and determined that the engine was scorched and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

I made a turn onto a highway. I got up to 45 mph after my turn and my car stalled. It felt like a was reared ended, my car came to just about a complete stop. It then began to shake and would not accelerate past 5mph to get me over to the side of the road. The check engine light came on. On 2/28/2026 my engine came on, I took it to Kia and they replaced my spark plugs, I got my vehicle back on 3/10/2026. At the beginning on 2026, Kia had my car for over a month for the same engine issues but said nothing is wrong with the vehicle. Back in December 2024 I had this exact issue of the car jolting and stalling. Kia said it was the transmission. I paid to have that replaced but it seems the vehicle is still having all of the same issues. My life was put at risk driving this 2021 Kia Seltos. I am very lucky that the cars around me were paying attention and did not crash into my car that came to a complete stop with vehicles going 65+ around me. Others lives could have been at risk had they crashed into my car. My car is once again back at Kia, with the engine light on again.

Engine stalled at stoplight. Was able to restart and pulled into closest parking lot where it began idling hard. Check Engine light turned on. Checked oil and it was bone dry (no signs of oil leak/burning beforehand). After adding about a quart of oil, while in park I revved the engine slowly, but it would stall out if it went over 3000 rpms and idle even harder. My basic code reader popped for P0014 and P0017 (crankshaft/camshaft position). Had to have it towed to the local dealer for safety. 75,400 miles on it and my VIN has not been part of recalls. Requesting an investigation to include more VINs as these issues point to a prior recall resulting in engine replacement.

I am filing a complaint regarding my 2021 Kia Seltos 2.0L. While driving, the engine made a continuous rattling noise, and the check engine light illuminated with code P0017 (Camshaft/Crankshaft Correlation). Upon inspection, I discovered the engine oil level was extremely low. After adding oil, the rattling stopped, but the P0017 code remains. I contacted my dealership, which refused to perform any recall or warranty inspection. I also contacted Kia Consumer Affairs, and my goodwill claim was closed with no follow-up. I am concerned this issue is related to a known engine defect affecting 2021 Seltos 2.0L engines, specifically problems with piston rings and excessive oil consumption, which can lead to engine damage, stalling, or timing errors. I request that NHTSA record this complaint, investigate whether my vehicle is affected by a defect, and ensure Kia provides proper inspection and repair coverage. This is a potential safety and engine reliability concern.

The contact owns a 2021 Kia Seltos. The contact stated that while driving approximately 35 MPH, the vehicle started to lose motive power. The contact stated that the brake pedal was depressed to stop the vehicle, and the vehicle stalled. There was no warning light illuminated. The vehicle was towed to an independent mechanic, and the contact was informed that there was an open recall for the engine and to take the vehicle to a dealer. The contact was informed of NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was towed to a local dealer, and the contact was informed that the engine had seized, and it was unknown if the recall was related to the failure. The vehicle was not repaired. The manufacturer was informed of the failure and advised the contact that the engine would not be replaced. The failure mileage was approximately 148,000.

My 2021 Kia Seltos (manufactured April 2020, ~94,000 miles) has the 2.0L Nu MPI engine affected by a known piston oil ring defect. Symptoms include piston noise, excessive oil consumption, rough idle, reduced power, and codes: P1327 (PNSS-detected knock), P0304 (cyl 4 misfire), P0017 (crank/cam correlation error). These indicate progressive cylinder wall scoring from improperly heat-treated rings, risking seizure or fire. Service history shows: • SC209 (Safety Recall 21V-259) inspection in Jul 2021. • SC209A (PNSS software update) in Feb 2022—explains why P1327 now triggers. • Other campaigns: anti-theft (CS2309/CS2312), AWD ECU (SC242/SC297), ECM logic (SA463). The defect progressed despite early recall work; dealers deny full engine replacement, citing prior completion or shifting coverage. SC209 has no mileage limit—progressive damage qualifies for re-inspection (vibration test, bore scope, compression) and free long block replacement if confirmed. You’ve faced loaner return demands before 2-week period, goodwill denials, and inconsistent coverage. The issue aligns with NHTSA concerns (e.g., AQ25001 on similar recall effectiveness).

On [XXX], check engine light came on with P1327 (PNSS piston noise detection). History includes SC209 recall in 2021 (inspection passed, PNSS software added Feb 2022). Now at 94,000 miles with misfire P0304 on cyl 4 and timing correlation P0017—dealer refuses full engine replacement under recall. Service dealer insisted it would be safe to drive 300 miles to Billings, MT from my home base location. Got 5 miles down the road to be left stranded to walk back with no service on a 13 degree day.

[XXX] Kia Seltos engine stalled and then stopped running. Driver attempted to turn engine over with no success. [XXX] The 2021 Seltos was towed to Kia in Jacksonville Nc. Kia Jacksonville stated engine seized, performed a compression test of cylinders with failure. cylinder 1 had a 135 psi, cylinder 3 had a 105 psi. It was stated that cylinder 1 and 3 had excessive scoring on the walls. Prior recall fixes included SC209 on Jul 19, 2021 with a dealer code of NC072. Recall SC209A was issued on 4/13/2021 per a car fax report. Recall for Sc209A was issued before the Sc209 recall fix. SC209A was not fixed on Jul19,2021. In February 2026 SC209A was updated after the engine stalled, had cylinder scoring and inadequate compression in cylinders. Owner of the 2021 Kia Seltos paid $1304,91 after a goodwill assist was authorized by the General or Regional Manager of Kia Jacksonville NC. Service Manager stated that Engine does not qualify for a replacement under the recall for not meeting the workflow criteria issued by Kia.

The contact owns a 2021 Kia Seltos. The contact stated that while driving 65 MPH up a slight hill, the vehicle shuddered significantly and failed to accelerate upon depression of the accelerator pedal. The check engine warning light then started flashing. The driver was able to pull over to the side of the road. The vehicle was taken to Hamlin Automotive on several occasions. The mechanic replaced 4 spark plugs, oil piston rings, and the camshaft; however, the failure persisted. The mechanic advised the contact that the failure might be related to the fuel injectors. Additionally, the mechanic had informed the contact that the vehicle might be experiencing excessive oil consumption. The contact received notification of NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling), and the vehicle was taken to the dealer for recall repair; however, the contact was informed that no issue was found upon inspection of the vehicle. The contact stated that while driving at 65 MPH, the check engine warning light started flashing. The driver pulled over to the side of the road. The vehicle was towed to the independent mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired due to the cost. The contact related the failure to the recall. The manufacturer was contacted and referred the contact to the dealer for assistance. The failure mileage was approximately 72,000.

Shuddered into limp mode at a stop sign. Has a sever shudder that throws it into limp mode, loses ability to drive in reverse and then loses ability to drive at all. Has issues shifting gears while driving causing the engine to rev itself while driving. Vehicle has left me stranded on multiple occasions. Has nearly 75,000 miles and I've put just over 4,000 of those on it since acquiring it at the end of October/Beginning of November.

I had my car to a reliable mechanic who informed me of open recalls on my vehicle. The next morning, while I was driving, the engine started making a noise and I called a local Kia dealership. I was making arrangements to bring the car in for them to look at when the car stalled, and I got to the side of the road. While I was looking up the number to call for a tow service, a driver passed me and informed me there was a fire under my engine. Within five minutes, the entire car was engulfed in flames. I was very lucky. Someone told me and I was able to get out.

My engine was replaced April 9. 2025 because of piston issues. I had taken it in a few weeks prior for terrible grinding noise, shaking, and slowing down. They didn't find anything wrong. It happened for a short time twice after and didn't take in as sporadic and would stop. Then it happened again for longer time. I had it towed to Kia again. During time in shop, I received a recall letter. Shop kept saying it would be done next day. After a few days I called and they said they were putting in an engine. I Picked it up and then two weeks before Christmas It started grinding sound and shaking etc. It was towed into Kia I bought from as my Kia roadside had expired a few days before. They ran diagnostic test and said they found nothing. I told they to try harder. Ran another test and supposedly according to some bulletin they upgraded some software back to what it was before engine replaced and the problem should be fixed. Only drove car 1 mile according to service papers I have. I have a 5 year old car with 24,000-25,000 mi. on and I am afraid to drive it. So far it has only happened when driving 45 mph or less. I will not drive it on turnpike or interstate. I want this recorded someplace so it is on the record for other with this issue.

My 2021 Kia Seltos has experienced repeat internal engine damage related to oil consumption. An intake camshaft previously failed and was replaced by Kia. The vehicle has now suffered a second camshaft failure (exhaust cam) with dealer documentation of oil starvation. Prior recall SC336 was addressed only with a software update and no mechanical engine inspection. Despite documented oil starvation and repeat internal damage, Kia and the dealer have refused recall reassessment or engineering (Techline) review and are treating this as an out-of-warranty cam failure. The vehicle experienced timing issues and near-total oil loss prior to scheduled service, creating risk of sudden loss of power while driving. I am requesting investigation of recall adequacy and engine defect.

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 asking me to pay for the new engine and transmission because they say it is out of warranty. That being said, had the recall problem been correctly resolved in 2021 I would not be having these same problems will fall directly in line with the issues resulting in the recall.

On 01/04/26, my vehicle’s Check Engine light came on and the engine was shaking. The next day, my mechanic diagnosed a P0301 code (cylinder #1 misfire), found signs of burning oil and cylinder damage in all cylinders, and noted the car had burned over 2 quarts of oil since the last oil change. He suspected faulty oil rings (previously recalled) and advised immediate dealer repair, warning of possible engine failure or fire hazard. The car had only 42K miles and should have been under warranty, but the dealer refused service because the code was cleared and said the warranty expired 4 months earlier. They claimed recall work was completed in June 2021 and would only help if the check engine light returned. Despite research showing codes are stored in the engine control system, the dealer insisted there was “no way to see the code.” After 10 days, the light didn’t return, so I picked up the car and continued driving, noticing a burning oil smell. On 02/02/26, I returned to the dealer, who offered only an Oil Consumption Test, stating it’s acceptable for the vehicle to burn 1.3 quarts per 1,000 miles—though the car’s oil capacity is just 4.2 quarts. The service advisor suggested I contact Kia USA, which I did on 2/06/26. Kia USA sent a repair order to the dealer, who claimed to be “working on the diagnosis.” Kia USA requested two more business days to follow up. GPS tracking shows the vehicle hasn’t moved except for parking since it was brought in.

Dealer has denied to look into recall claiming that it is part of a warranty extension when it is a safety recall due to the issues I am experiencing. The car began to stall not even a year into me owning the vehicle. I had barely had the car for 4 months, not even enough time for my first oil change and my car stalled on me in a parking lot as I was driving. It shut off. It has done this multiple tomes randomly since. Then one day after work my car wouldnt start at all and when we eventually got it started, it would then stall every 15 feet that id be able to drive it. The entire car just shuts off every time. All of my lights were still working, but the engine itself would shut off.

I am reporting a failure of the remedy for NHTSA Recall 25V099 (Kia Recall SC336). My 2021 Kia Seltos with the 2.0L Nu MPI engine is exhibiting severe engine knocking and high oil consumption. Despite providing video evidence of the knock to Archer Kia (Houston, TX), the dealership refuses to acknowledge the defect or perform the required borescope inspection. ​This defect is a documented fire and stall risk. I am being denied a loaner vehicle despite having a medically fragile child who requires this vehicle for surgery and doctor appointments. The dealership is utilizing 'oil consumption tests' as a delay tactic to avoid performing the recall-mandated engine replacement. This vehicle is unsafe to operate.

The Kia was traveling approximately 45 - 50 mph and struck another vehicle that had pulled out from a stop sign. I had my hand on the horn and the airbags did not deploy on impact.

The contact owns a 2021 Kia Seltos. The vehicle was serviced under NHTSA Campaign Number: 25V099000 (ENGINE AND ENGINE COOLING), but the failure occurred. While the contact's wife was stopped at a traffic light, the vehicle stalled. While the accelerator pedal was depressed, the vehicle lunged forward and then stalled. The contact's wife was able to coast to the side of the road. No warning lights were illuminated. The vehicle failed to restart. The vehicle was towed to the dealer, where it was determined that there was no oil in the engine, causing the exhaust pin to be sheared off the exhaust camshaft. The vehicle was not repaired. The dealer informed the contact that when the vehicle was serviced in August of 2025, the engine was inspected; however, the recall repair was not performed. There were no oil stains found on the ground, and there was no warning light illuminated, indicating that the oil level was low. The vehicle remained at the dealer unrepaired. The manufacturer was made aware of the failure and refused to perform the recall repair. The failure mileage was approximately 110,000.

The car makes a jumping/jerking movement & at times, something that seems like a misfire happens. All lights go on and the car will do that jerking issue & become un drivable. This happened to me on the road and I was afraid for my safety as I couldn’t get my car to a safe place immediately. Brought it to my mechanic and he gave me forms of a recall regarding 2021 Kia Seltos which is what I have.

We bought this 2021 Kia used and within a year the engine blew. There was a defect in the motor. It had just passed the warranty mileage.

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.

When driving the car for a prolonged amount of time at a higher speed, the emissions from the motor back up into to the cabin once the car is stopped.

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
