Labor charges for replacing engine?

It's junk , don't buy another one

The extended warranty should show the deductible if any, so the deductible is what you would pay. My extended warranty has a 100 dollar deductible I have used it twice, once when the transfer case bearings went and also when the starter would not pull the drive back.

Beat up Chevy is right, these are not the most reliable vehicles.

Thanks to all. We've learned that our Sonata is under full extended warranty. The engine and labor are covered! Whew!!

You got lucky there. Hope it works well for you.
