2021 Kia Seltos

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.

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.

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).

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 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 NHTSA 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 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.

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.

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.

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.
