Hyundai Sonata 2003 Problems

Valves bend because they come into contact with pistons. It could be that the belt wasn't installed correctly and the cam timing is out, it could be that the belt tensioner has failed and the belt has jumped a couple of teeth as a result, it could be a problem with the lash adjuster.

MY Hyundai contact tells me he has not experienced the clutch problem you have and says you would have to be riding the clutch hard to get that sort of wear. The clutch is generally regarded as a consumable item by most carmakers, but that presumes it wears out in a normal fashion. In your case, he reckons you should be pressing for it to be covered under warranty, and I agree. Unfortunately, there's not much choice but to replace it, so I would suggest you make it clear to the dealer and to Hyundai that you believe it is a warranty issue before it gets pulled apart, then be prepared to argue your case.
