2021 Kia Seltos

I am requesting a formal review of an engine failure involving my 2021 Kia Seltos LX with the 2.0L engine. At approximately 103,000 miles, the original engine failed after losing nearly all of its oil. There was no obvious external oil leak or oil puddle, suggesting that the engine may have been consuming oil internally. Earlier in my ownership, the vehicle also unexpectedly shut off while operating. I paid out of pocket for a replacement engine and installation. Within approximately one to two hours of receiving the vehicle back, the check-engine light began flashing. The diagnostic information reportedly indicated piston noise, even though the replacement engine appeared to run smoothly. These circumstances appear similar to the piston-ring condition described in safety recall SC336/NHTSA 25V-099, including excessive oil consumption, cylinder damage, abnormal piston noise, engine failure, and possible loss of power. However, Kia’s online system currently shows that SC336 is not open for my VIN, and the dealer found no record that the recall had previously been completed. I understand that my VIN may not currently be included, but I am asking Kia to investigate whether my original engine experienced the same defect, confirm in writing why my VIN was excluded, and review my case for reimbursement or goodwill assistance. The failure occurred only about 3,000 miles beyond the 100,000-mile powertrain warranty, and I have already incurred substantial engine and labor expenses. Please open a formal case, review my vehicle’s production and engine records, and provide a written determination. I can supply the VIN, repair invoices, proof of payment, mileage records, maintenance documentation, diagnostic codes, towing records, and replacement-engine information.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed and turning into the driveway, the check engine warning light illuminated, and the vehicle stalled. The vehicle was towed to the dealer, and there was no oil in the engine, and metal flakes were found in the camshaft. The contact associated the failure with NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling); however, the VIN was not included. The dealer diagnosed the vehicle with camshaft failure, timing failure and recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 71,707.

Randomly started having engine issues in July 2026. Had an appt with Kia dealership and said my engine needed to be repaired with assumptions on what the problem is. They claimed it had nothing to do with the engine recall on my Kia and that it was my responsibility to pay for the repair. There has been 2 separate recalls on this car for engine issues which Kia is refusing to deal with or take care of. My car has been serviced by Kia dealership since I bought it in 2020, I also noticed in all my service receipts/reports that they were putting the wrong oil in my car and who knows if that is what caused my engine to start having issues. Car is unsafe to drive.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at 45 mph the engine experienced a complete loss of automotive power, and no warning lights were illuminated. The vehicle was towed to a local dealer where it was diagnosed and the contact was advised that the engine was faulty and needed to be replaced. The contact associated the failure with NHTSA Campaign Number : 25V099000 (ENGINE AND ENGINE COOLING). The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 120,000.

While driving normally at approximately 55 mph on the highway, the vehicle suffered a sudden, catastrophic, and spontaneous structural failure of the rear driver-side suspension and drivetrain. Without striking any road debris, potholes, or other vehicles, the entire driver-side rear wheel, wheel assembly, and structural axle components completely fractured and ejected from the moving vehicle. An eyewitness at the scene explicitly confirmed the nature of the failure, stating on video that they observed the 'entire rear axle just come right out' while the vehicle was in motion. The vehicle sustained extreme structural damage, completely disabling it on a high-speed highway and creating an immediate, life-threatening situation. The vehicle is a low-mileage Certified Pre-Owned (CPO) unit with under 24,000 total miles on the odometer, indicating a severe manufacturing, material, or component fatigue defect rather than wear-and-tear. There were no warning lights or symptoms prior to the failure. The vehicle is currently being held at a recovery yard and is fully available for inspection upon request. A formal defect investigation has been initiated with the manufacturer, and the insurance provider is inspecting the sheared axle and metal components for structural forensic analysis

The contact owns a 2021 Kia Seltos. The contact stated that on March 13, 2026, the vehicle was serviced under NHTSA Campaign Number: 21V259000 (Engine); however; the spark plugs were not replaced when the vehicle was repaired. The vehicle was taken to the dealer, where it was diagnosed with a misfire in the engine associated with the spark plug. The dealer stated that the failure was not associated with the recall. The contact stated that the failure was caused by the dealer not installing new spark plugs during the recall repair. The manufacturer was made aware of the failure and stated that the recall repair was performed and was out of warranty. The failure mileage was approximately 92,000.

Purchased new, Feb, 2020. Received piston ring defect recall notice (SC209). Serviced by dealer July, 2021. In 2025, noticed engine knocking noise. Car stalling out. No warning lights. Car 3 quarts low on oil. Consumption tests proved excessive oil used. Piston ring soak (Kia's "solution") did nothing to reduce oil use. After ring soak, oil still low at 1000 mile test. I stressed my belief the engine needs replacement and a ring soak is a band aid, NOT a permanent fix. Was asked to drive 3000 miles, check the oil, and top off if necessary. The engine was noisy during this test. At the 3000 mile mark, I pulled the dipstick. Bone dry. Drove to the dealer and told them it was very low. They sent me to the lounge and said they would pull the car in and come get me. When they didn't come, I went to check, to find a service rep putting oil in my car out in the parking lot. He claimed it was only about one quart low. Then, another consumption test at 1000 miles. Low again. They wanted to do another 1000 mile check after this. They changed the oil and told me to come back at 1000 miles. When I came back, I asked to be present to witness the oil level. They took me to the lounge, said they were pulling the car into the shop, and would come get me. Again, they pulled the stick without my presence, and told me it was full. Now, they want me to do another 4000 mile test. I took the vehicle to two independent mechanics. Their borescope inspection proved engine damage. I have filed a complaint with Kia Corporate and it seems to be falling on deaf ears. I demand a full refund at this point! Kia has lost my trust, both in quality and customer service. I have all the maintenance records and a written statement regarding engine damage, along with photos from the borescope.
