   Complete engine failure in July of 2024. When the car was sold to us it was under recall and not repaired and we were not told there was a recall. When the engine failed we were told we were at fault because we failed to get the recall addressed.

   The engine experienced catastrophic failure. A piston punctured the engine block, likely due to failure of the connecting rods, an issue known to be associated with the recalled Theta II engine. The engine is still in the vehicle and available for inspection upon request. We were scared and felt seriously endangered during the incident. The engine failed suddenly while we were driving on a busy highway. After a loud clunk, the vehicle immediately lost acceleration and would…

   I purchased a 2014 Hyundai Tucson with the 2.4L Theta II engine, which has since experienced complete engine failure due to bearing wear. The Hyundai dealership diagnosed this as the same defect covered under Recall 20V-520 and the Kinnick & Coats v. Hyundai class-action settlement (Case No. 8:17-cv-00838-JLS-JDE). Under the terms of that class action, this defect — specifically premature bearing wear leading to engine seizure — should be covered. However, Hyundai Corporate…

    As with many Hyundai vehicles, soon after I hit 100,000 miles, there was unbeknownst to me and oil leak that caused the engine to seize. There was no indicatior lights warning of the issue. My car’s has been maintained, and although this is under warranty, Hyundai is refusing to fix the issue because I cannot produce oil receipts for the past 4 1/2 years that I’ve owned the car. Those that I have produced, they say are not enough. The service station that I normally had my…

    A recall caused my engine to fail, and needs replacing. it is i believe “campaign 966” They are claiming that i needed to have the system software updated PRIOR to the engine failing. they know that their recall is responsible for the engine failing, but they are trying to go around it by saying that it needed to be fixed before the engine gave out. They NEVER, not one time, reached out about this needing to be fixed. not by email, or regular mail. Nothing. i’m reading…
