It's probably not the wipers. However, you can give them a good wipe down with an alcohol wipe. You'll be amazed at how much black gunk comes off. Clean off the windshield with a good automotive glass cleaner. Do NOT use wax on the windshield! Maybe a coating like rain-x, but I never really found these to be all that effective.

Strange, I've never had an issue getting dealer to swap on new wipers (under warranty ).
