NHTSA Complaint #11687631 — 2021 KIA SELTOS

On [XXX], while driving my 2021 Kia Seltos (VIN: [XXX] ) on the highway at approximately 70 MPH, the engine suddenly revved slightly higher and then completely shut off without warning. This caused a loss of power, making the vehicle difficult to control and nearly resulting in a significant accident with surrounding traffic. Fortunately, I was able to coast and pull over to the shoulder safely, avoiding a collision. No warning lights illuminated prior to the incident, and there were no other noticeable symptoms beforehand. The vehicle was towed to Classic Kia in Texarkana, TX, where technicians diagnosed engine seizure with no oil present—a clear symptom of excessive oil consumption and cylinder wall damage linked to faulty piston oil rings. During a call with Kia on September 16, 2025, they confirmed two prior recall repairs in 2021 and 2022: one for Recall SC209 (NHTSA 21V-259, addressing piston oil rings in 2021 Seltos with 2.0L Nu MPI engines) and another related repair not directly tied to SC209 but addressing similar engine issues. These repairs failed to prevent the defect, as evidenced by the seizure. This matches the piston ring defect in SC209 and the expanded Recall SC336 (NHTSA 25V-099, covering 2021–2023 Seltos), which can cause seizure and fire risk. NHTSA’s 2025 audit of Kia’s engine recalls notes ineffective fixes, with owner complaints of post-repair failures. This incident posed a severe safety hazard, as engine seizure at highway speeds risks crashes, injuries, or fatalities. I urge NHTSA to investigate this as part of the audit and compel Kia to provide a permanent remedy, such as engine replacement or vehicle buyback under warranty/lemon laws.
