Dunno. The head mechanic told me locally that there is a lot of noise coming from the underside of the BLOCK.
They flushed the engine and changed the oil and filter but it still sounds bad.
I had a tow truck come pick it up and take it to Hyundai Service department about 20 miles away.
They don't want to mess with it as it should be covered by the 100,000 mile warranty. I guess we'll see.
