2021 KIA SELTOS- Whitewright, TX
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)

2021 KIA SELTOS- Fort Walton Beach, FL
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.

2021 KIA SELTOS- Assonet, MA
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.

2021 KIA SELTOS- Collinsville, IL
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.

2021 KIA SELTOS- Sidney, MT
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).
