The catalytic converters fail about every 5 years. The rear corners of the wheel arches are normally rusted.
Of course i dont close it that way... I bring it by hand 5-6 inches above closing point and thats enough. Even less if any door/window is opened.

I thought my catalytic converter is bad because i barely passed eco test this year but i think its short drives and not achieving work temp what affected it and that it will be better now since i drive it much more than before. How do you diagnose a bad catalytic converter?
