Thread: catalytic converter

why so expensive? can't an aftermarket be used?

mine went up last year at 78,xxx miles and replaced under warranty by the dealership.

hey everyone. has any one had to replace the cat. conv. on 04 or that gen. yet. if so what happened before they went out? i had one on the driver side go out. sounded like a grinding noise by the oil pan and then started losing power. triple a said the conv. collapsed causing exhaust to go back into engine. approx. $1500 to replace. thanks,scott

I had the same thing happen to me earlier in the month. Total lack of power at high rpms.

I resurrect this post rather than starting a new one. Ford does warrant the cat for 8yrs/80,000 miles (I think this is govt. mandated). Anyway, the cat on my wife's 2004 Ex. went bad in September (@68,000 mi.). Just prior to the cat failure, it started throwing codes for the O2 sensors, so I replaced them all. The cat failure was similar to others described - popping/rattling noise, loss of power, etc. Here's the big FYI from Ford -...

Yup, it's a Fed law that the Emission system components are warranted for up to 8 years / 80k miles. Below is what's covered for this timeframe. The list of covered components is much more extensive in the 2 year / 24k timeframe....
