Owner Narrative

I am writing to formally log a safety defect complaint regarding a severe mechanical failure in my 2014 Hyundai Elantra, equipped with the Nu 1.8L engine. The vehicle has been professionally diagnosed with severe internal engine knocking stemming from catastrophic piston slap, a manufacturing defect inherent to this engine family block that causes premature cylinder wall scuffing, piston ring degradation, and unmetered oil loss. The National Highway Traffic Safety Administration has previously acknowledged that manufacturing issues in Hyundai engine blocks can cause rotating internal components to fail, leading directly to sudden, un-alerted engine stalling at highway speeds, a severe and immediate safety hazard to drivers, passengers, and surrounding traffic. Despite this being a well-documented mechanical defect (originally addressed under the [XXX] , et al. v. Hyundai Motor America Class Action Settlement / Service Campaign TXXK), Hyundai Motor America is currently refusing to remedy this hazardous component. The manufacturer has repeatedly denied corporate assistance based strictly on an arbitrary calendar timeline (stating the vehicle has passed the 10-year settlement window). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
