Asked by Feb 04, 2012 at 02:38 AM about the 2005 Toyota 4Runner Sport Edition V6 4WD

Question type: Maintenance & Repair

So what is it about Toyota's catalytic convertors that make them fail so quickly?  I have replaced 2 already on my 2005 Sport Edition and now the dealer is telling me both are going bad and need to be replaced AGAIN!  So let me get this right 4 cats x $1800 each.............sounds like defective product to me!

Sounds very strange that you'd have to replace them so often. Unless there's damage caused by them being hit, they should last ages. I'd ask the dealer what exactly is failing in the cat, is it the casing, the ceramic insides or the wadding ? I've had many cars over the years and never had to replace the cat on any of them. What I'm also thinking is, that it's not the cat that needs replacing it might be the lambda (oxygen) sensor that's failing.

So my dealer told me I have 4 cats on my 4Runner.........really I think there are 2 precats and 2 cats, after replacing 4 Toyota cats at $1800 each I went with Magnaflows. Come to find out the precats where the problems.........would have been nice to know right away, they are $385 each............I wasted alot of $ for no reason follwing what the dealer said problem was. Toyota 4Runner owners forum is how I found out what problem was, not dealer.
