Anybody else had their catalytic converters fail? I already replaced one of these on my '05 HAH, and now the 2nd one is failing. At least, that's what the diagnostic trouble code says, when I took the car in with the Check Engine Light illuminated. The dealer is ordering the part.

I did not know until today that this car has 2 catalytic converters. My car has only 41K miles. It's a good thing this is under warranty. Turns out that the catalytic converters are covered for 8 years, 80K miles.
