My wife's 2005 OBW just had it's second catalytic converter go south. The first was shortly after 15k and this one went at 22.5k (conveniently enough at a service interval). The dealer service manager says it's the way California gas is formulated and the ECU settings required. Everything else on the car passes with flying colors.
Question: Has anybody else seen these kind of catalytic converter failures at close to this high of a rate with either newer Subies or any make/model of vehicle? Any recommendations (besides moving to a different state)?.
Just a quick tidbit for the few of you who may appreciate American vehicles - I just retired a '96 Ford truck which, aside from an alignment issue that was resolved and the inevitable oxygen sensor failure, only asked for regular maintenance through it's entire life, even the original battery latest 9 years.
