Catalytic convertor 2002 SLT 5.3

[billyb22]

Anyone have problems with their late model Yukon Cat. convertor?
Just outside of warranty, my '02 sounds like its going to loose a rod!!
I braved the sub-zero temps to get under there to find the source.
I bang my hand on the passenger side convertor and recreate the noise.
Seems like the 'guts' have crumbled and are rattling in there - sounds alot like a rod knock.
This assembly includes 'y' pipe and 2 convertors.
Dealer price $550 plus $40 core plus $35 in gaskets!!
Plus $150 install.

Are you sure it is not covered under warranty? I don't have my Yukon today with me to check the owner's manual; however, the cat is covered by the emissions warranty which is longer than the bumper to bumper 3 year warranty.

Of course the dealership didn't offer that, but I will be checking into it.
Thanks.

I called customer service and they helped me set up the appt. at the dealership. I will pay the diagnosis fee $60.00. They tell me if it is the convertor, it will be covered up to 80,000 miles.
They certainly did not offer this whem I called about the price of the part. They even asked the VIN and I complained about the low mileage on the truck. Thanks for the heads up!

My Yukon is back now. Dealership replaced catalytic convertor assembly and oxygen sensor FREE of charge. They even waived the diagnostic fee of $60. This would have cost me $825 if I hadn't gotten the heads up.
Thanks sooo much!! **** emissions are covered to 80,000 miles ****
