NHTSA Complaint #11711389 — 2013 HYUNDAI SONATA

My 2013 Hyundai Sonata (VIN: [XXX] , 2.4L Theta II GDI engine) is experiencing symptoms consistent with the known Theta II engine defects covered under prior NHTSA recalls (e.g., 17V-226) and the related class action settlement for connecting rod bearing wear due to manufacturing debris restricting oil flow. The vehicle has begun exhibiting [describe your specific symptoms here, e.g.: "a loud metallic knocking/tapping noise from the engine that increases with RPM, especially during acceleration or at highway speeds; reduced engine power and hesitation; illumination of the check engine light and/or oil pressure warning light; excessive vibration; or sudden loss of power/stalling risk"]. These issues have [escalated/worsened over time or occurred suddenly while driving]. This poses a serious safety hazard because premature bearing wear can lead to complete engine seizure or stall without warning while the vehicle is in motion, potentially at highway speeds, resulting in loss of motive power, inability to maintain speed, or increased risk of collision, injury, or fatality. I have properly maintained the vehicle with regular oil changes using the recommended full synthetic oil [add if true: "and can provide service records showing no evidence of sludge or neglect"]. Despite submitting an appeal/claim under the Hyundai Theta Engine Class Action Settlement (Case Number XXX), I received confirmation on December 30, 2025, promising a decision within 14 business days, but as of January 16, 2026, there has been no response or update despite follow-up attempts. This ongoing delay prevents me from obtaining the necessary inspection, repair, or replacement under the extended warranty/safety coverage, leaving the vehicle in a potentially unsafe condition. I am requesting that NHTSA review this as part of the pattern of Theta II engine failures in 2011-2014 Hyundai Sonatas, which have led to thousands of similar complaints, recalls, and investigations into untimely INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION AC
