"Engine failed while driving, Took it to dealership and the engine is seized. We were declined by Hyundai an engine replacement even though the Theta 2 engines have a lifetime replacement warranty because these engines are known to fail. They constantly deny due to 'severe owner neglect' because people do their own oil changes."
"Engine experienced severe metallic knocking and loss of power. A certified Hyundai technician confirmed a FAILED Bearing Clearance Test (RO #354331). Hyundai Motor America is refusing to honor the Engine II Class Action Settlement warranty, citing internal code A99 because the vehicle was purchased at an auction, even though the title is CLEAN. This pose a safety risk of engine seizure and potential fire."

All figures come from the U.S. National Highway Traffic Safety Administration (NHTSA) public APIs: the Office of Defects Investigation complaint database, the recalls database, and NCAP safety ratings, retrieved September 7, 2026.
Complaints are self-reported by consumers and are not verified by NHTSA or by this site. A single complaint may cite multiple vehicle systems, so system mentions can sum to more than the complaint total. Complaint volume is influenced by fleet size, media attention, and recall notices, and is not by itself a measure of defect rates.
