Thanks for the prompt response. The Check Engine light had come on.
She brought it into the Honda dealer where she bought it to have it
checked out.
They said they checked it out but made no mention of a catalytic
converter problem and also suggested she have he 100,000 mile
servicing done. She did have it done at a cost of $400 and went on her
merry way. Two days later the Check Engine light came on again. It was
a few weeks before she could get back to the distant dealer. When she
bought the car used she got a 100,000 mile warranty, which is moot
because this failure occurred after 80,000 miles, the point at which
even under the 100,000 warranty the CC is no longer covered.

I somehow doubt it would be wise to buy a used CC at a junk yard not
knowing whether it is any good. For many parts that is a prudent
option. But not, I think, for a CC.

Thanks for your help, though

Hi,
Tried wrecking yard for a good used one? Wonder what caused it?
There must have been warning symptoms B4 it failed.

Two separate Honda dealers have diagnosed a failed catalytic converter
on my daughter's 2001 Honda CR/V. One wants $1,100 to fix it. The
other simply says, "Thousands." The catalytic converter needs to be
replaced. The car has 105,000 miles on it.

Can anyone give me an authorative real world estimate of what this
repair should cost, including if done by someone other than a dealer?

Thanks
