NHTSA Complaint #11580596 — 2018 HYUNDAI SANTA FE

My vehicle was turning off without any warning, last oil change was in October 2023, and had the oil changed this month. Engine started making loud noises from top, and eventually louder knocking noises from below. We towed vehicle to the dealer where we purchased at Balise Hyundia in Springfield MA. The vehicle has 84,000 miles and we've always maintained it. There were no warning indicators that there was an issue with the engine. After further research I've discovered numerous articles and complaints regarding Hyundai's 3.3-liter engine after certain number of miles. The engines are failing, and I'm concerned we may be victims of an issue that has existed with these engines. This is a safety issue because there is no warning the engine is failing, the car turns off without warning, and the potential of an overheating engine causing a seizure and fire is always a concern.
