What owners wrote
“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 seized on me, lurched forward, then engine light starting flashing and I could barely accelerate anymore. Had to go very slowly to make it home. My local autoshop says this is very common with Hyundai's and there was a recall for bad engines for this.”

Should you keep driving it?
This page can't tell you that. 0 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
