Overview Over approximately six months, I reported persistent drivability concerns to Hyundai on Perryville — specifically hesitation, engine trembling, power loss on acceleration, and eventually a flashing check engine light, particularly when the engine was cold. Despite multiple dealership visits and over $1,500 in out-of-pocket expenses, the root cause was not identified until my fifth visit: a clogged catalytic converter. Hyundai Motor America determined the repair was not covered and declined to explain the diagnostic basis for that decision. When I sought a second opinion at an independent shop (recommended by the dealership), that shop ignored my explicit instructions not to drive the vehicle, drove it, and the car broke down in their care. Their own invoice now states the vehicle needs a new motor. I am filing this complaint to document the full pattern of negligence, misdiagnosis, and failure of care by both parties.

This vehicle had to be towed to a mechanic who said the engine had seized up and that the oil is gone from the engine and that I would need to have it sent to a Hyundai dealer.

This vehicle was towed to a Hyundai dealer who confirmed that the engine was locked up and that an oil sample found metal in the oil. The dealership recommended to replace the engine with a used one for over $11,000 which I declined then charged me $160 for evaluating. No warning lights or indicators were ever showing any issues. We did notice sometimes after an oil c...

The engine burns oil fast. You have to replace oil on a regular bases. The car also looses fluids fast as well. This causing the engine to over heat. This causes the cylinder to head blow.
