Engine Exhaust System problems of the 2006 Toyota Scion Xa

Charcol filter is sending check engine message causing car to fail emmisions test.

My check engine went on and I checked for all possible problems. Gas cap etc. I drove for several trips and when the light didn't go off I called my scion dealer. I told him what was happening and he said to bring the car in at my convenience to have it checked. I asked him if I was still under warranty and he said yes because I only had 27,000 miles on the car. They inspected it and found it to be the charcoal canister which he said had a pin hole in it. He said it would cost $531. 03 plus tax to replace it. I then said that it should be covered under my warranty. He said no because it over the warranty time. I purchased the sionxa on Dec 5th 2005, but did not receive the car until the 28th of Dec. Any way this is an emissions problem which is covered under my 50 thousand mile warranty. He said it is not an emissions problem and I will have to pay $45. 00 for the check up. And the $531. 03 for the replacement. I will not be paying that money for and obvious manufacturer defect. I will be getting rid of my Scion Xa and getting a vehicle which fixes defects. Toyota replaced all charcoal canisters with a good one after they found the defect in my VIN # area for the 2006 xa's. There should be a recall on this part. Since the soul purpose of the filter is for emissions than it should be replaced by the manufacturer at no cost to the consumer!!!.
