My 05 with 46k on it threw and engine check light recently. Brought it in today and they said the CAT. has failed and they need to replace the exhaust mainifold and the Cat--under emmissions warranty.

Funy thing is, they already changed the exhaust manifolds under the TSB so now I will be on the 3rd set.

Has anyone else had this issue?

The TSB was for the fluttering ticking noisy exhaust manifolds. I had them replaced and they were quieter, now still quite, but no good emmissions wise, so I get new ones again.
