The oil pan is consistently out of oil. It burns up. Causing the engine to stall, shake or grind at times. We have been having this problem for 2 years now. Taken it to 2 different dealerships. They confirmed it needs a new engine however Kia will not replace it for us. It is a known problem with these vehicles and there is a lawsuit currently going on. We have receipts from dealerships, we have been stranded on the side of the road many times and can not drive it due to risk of fire or engine seizing. We used to keep oil in the car at all times and check it frequently. Now we are afraid to drive it and damage it any more. We have done all the recalls and because the one recall was a piston ring system update, we aren't covered under the recall then. The system must be faulty. We do get a check engine light or oil light on when the car stalls, otherwise we just have to keep watching the oil that keeps disappearing. Kia has denied us the new engine after asking for an Out-of-Warranty Goodwill Breakdown for the car. The first owner went 10,000 miles without seeing a dealership and we did as well when we first bought it. The problems started at 57,700 miles. The car is junk and they wanted to give us a deal on the new engine $7,750 out the door. WOW, it's not our fault the engine or the piston rings burn the oil and are burning the engine up. Kia is at fault, their cars are crappy.
2021 Kia Seltos engine complaints
Page 3 of 10: complaints 41 to 70 of 280, newest first, as owners wrote them.
I was driving on the highway at 63 mph. I went to change lanes and pass the vehicle next to me so I gradually went up to 75 mph. Then there was an explosive metal sound and white smoke filled my cabin and under my hood. I could smell oil from inside the vehicle. I pulled over, opened the hood and let it cool off. After it cooled off I checked the oil and found there was none. I then called roadside assistance through my maxcare extended care plan. They sent a tow truck to pick up the vehicle and sent it to the nearest auto shop which is called precision tune auto roughly 1.8 miles away from where the car was parked. The tow truck dropped it off at 11pm. I called the next day in the afternoon to provide my contact information and wat happened. They ran a diagnostic on the vehicle and said either a piston or rod blew through the oil pan which caused all the oil to leak out from underneath the car and said the engine needed to be fully replaced.
Multiple times the car has shut off while driving. It did receive the PNSS sensor thing from the dealership 2 years ago. It has done this while my wife and kids were in the car in a busy roundabout. There are known engine issues with this model. Kia dealership is dragging their feet and “can’t recreate the issue.” (because it happens randomly) They ran “tests” and they all came back with “no issues.” Dealer states that they are waiting to hear back from the tech line at Kia. Service advisor said to me that they may just give me the car back because they can’t find anything wrong. And the “we would essentially have to wait for a complete component failure.” It is available to be inspected. There were no warnings at all and it has done it at random times in seemingly normal conditions. It receives routine maintenance and after my last oil change my mechanic (not from Kia) said that they found metal shavings in the oil and that there was only 1 qt of oil. And recommended that I talk to the dealer about engine replacement. The last time it shut off was June 4 and and it has been at the dealership since June 15th.
The vehicle started loosing engine power. The vehicle stalled while driving 5-6 times, this posed a danger to driver, passengers, and others. A car accident can easily happen when the engines dies. Power to all systems was lost, including steering and brakes. No warning lights or check engine lights appeared at anytime, symptoms started a week before. Vehicle was approx 3 quarts of oil low. It was about 2 months from previous oil change. Other 2021 Kia Seltos have an open recall for defective piston rings (SC209 or SC336.) The vehicle was taken to the nearest Kia dealership. They stated this VIN did not fall under the recall and there was nothing they would do. Kia was called directly and also stated no assistance would be offered. No inspection or diagnosis has been made as neither the dealership nor the manufacturer is willing to assist. This vehicle should fall under the recall.
Driving my car on Interstate highway going approximately 65 miles an hour, and the engine just stopped. It started chugging.. I then check the engine oil stick, there was very little Oil, and it was very dark and thick. Got the car home and it’s been sitting ever since. I’m going to have to take it to Kia to have it checked. I spoke with corporate they said that if the recall repaired was completed, because there is still engine trouble and that I should be it taken to the closest dealership. I haven’t checked ones before at Kia near me and they told me I just needed to change the more often. My son has changed the oil twice since then, and the problem has gotten worse instead of better.. So let’s see what the next dealership says about the situation. I’ll keep you updated.
Engine problems. Car stop running and I had it towed to a local KIA dealer in Medford, Oregon. They said the engine didn't have any oil even though it wasn't time for my next oil change per the mileage sticker. They said the engine has to be replaced. I'm waiting on KIA's approval since it is still under warranty. They have had the car for a week. It's a 2021 KIA Seltos and I'm assuming other people are having the same issue.
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 under any applicable recalls, warranty extensions, service campaigns, or defect-related repair programs. I have been informed that my vehicle is not covered; however, I respectfully request that Kia reevaluate my VIN and investigate whether the stalling condition is connected to any known engine-related defects or recall conditions. I am requesting that: • Kia provide towing assistance if the vehicle is unsafe to operate. • Kia perform a complete diagnostic inspection at no cost. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
The contact owns a 2021 Kia Seltos. The contact stated that the vehicle was intermittently overheating and losing motive power while driving. The contact stated that the vehicle failed to accelerate properly. The vehicle was taken to an independent mechanic, where the spark plugs and ignition coil packs were replaced; however, the failure persisted. The contact returned the vehicle to an independent mechanic and was informed that the catalytic converter needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 106,000.
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 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 federal safety agency 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 (the federal safety agency 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 federal safety agency, 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. Independent automotive reports confirms that this defect has affected over 137,000 vehicles, including 2021 Kia Seltos models, and in many cases requires full engine replacement due to internal damage caused by faulty piston rings. Additionally, documented consumer complaints describe the same pattern I have experienced—excessive oil consumption with no external leaks, worsening engine performance, and dealerships attributing the issue elsewhere despite clear alignment with the recall defect.
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 the federal safety agency 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, seizure, and risk of fire. My VIN returned 0 unrepaired recalls on April 22, 2026, placing it outside both recall populations. However, my vehicle has the identical engine, model year, and failure mode. I request the federal safety agency investigate whether both recall populations adequately captured all affected vehicles, including those manufactured outside the stated production date ranges.
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 the federal safety agency 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!
Vehicle: 2021 Kia Seltos VIN: [XXX] Mileage: 71,728 Recall: the federal safety agency 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 personal life.This is a federally mandated safety recall that was supposedly completed before our CPO purchase ([XXX]) with no disclosure. The temporary oil change and code clear did not fix the underlying defect. We request that the federal safety agency require Kia to immediately authorize the full engine replacement at Rairdon Kia based on the documented history, without requiring us to drive an unsafe vehicle.

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 federal safety agency 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.

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 the federal safety agency 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 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)
