Just curious, how many miles do you have on your 2009? I just purchased a 2009. I love it so far but I'm paranoid something is going to break. Isn't is early for a catalytic converter to go? Did the dealer explain what happened? Finally, did they replace it under warranty? I believe I read another post here that said catalytic converters were required under Federal law to be covered for 8 years. And thanks for telling us how your story ended.
