I have a '04 Santa, 2. 7 with 87,500. I replaced the purge valve about 2-years ago, because the car would not start after fill-up. I had no codes, car ran fine. I researched on Hyundai forums, it seemed to be common. Bought the part at the dealer, did it my self, pretty easy, just busy work. If you cannot find the repair on line, I'll dig-up the page and post it on TDR. I hope this helps. I never thought of pursuing it as a emissions warranty... My dealer has been good to us for the minor warranty issues: door cladding, cargo cover not rolling-up, air/heat fan switch.
