Catastrophic engine failure. With no prior indications, the engine seized while driving on side street at 25mph. Engine blew hole in block and dumped engine parts, including piston rod, piston and engine block remnants, and oil on street. Very dangerous as power steering stopped and was unable to turn. Very low miles, 40,680, with all maintenance performed by dealer. Filed a report with Hyundai USA, no action taken.
The vehicle developed a low end engine rattle during idle. The noise would go away on acceleration. Today the engine failed. It won't turn over at all. It's seized up. I checked the oil and the oil is full. I bought this vehicle when it was 2 years old. I've used synthetic oil and changed the oil every 3 - 4,000 miles. The symptoms are identical to the ones on the sonata and other various models. My vehicle was manufactured here in the states. An engine is a huge expense. Especially if it's due to manufacturer negligence. I will never buy another Hyundai or kia again at this point.
