Catalytic Converter Issues

I have a 2006 Access Cab 4x4 I4 that is having catalytic converter issues. In November I noticed a strange exhaust noise and took my truck in to the dealer. I was also noticed poor fuel mileage and a loss of power. They said that one of the catalytic converters was coming apart and replaced it. A few weeks ago I hit a pot hole on a dirt road and started hearing the same noise again. I know the hole wasn't deep enough for me to have hit my exhaust. I was wondering if anyone else was having the same problems or am I just the unlucky one here.

 

It is going back as soon as I can slow down at work for a couple of days. Our fire season just started up and everybody is jumping.

 

Even If you hit your exhaust that would not really harm your cats. Maybe you just got an unlucky one the first time. I bang and scrap exhaust all the time and I am only worried about leaks at the flanges.

 

I am sure with all of the knowledge here there has to be more than 2 responses

 

I have the 2.7. There are 3 cats on there. It was the last one when they replaced it in the fall

 

It is something. The service rep showed me the price for one. $1300 dollars. And that was dealer cost. I hate to think that this may be an ongoing problem.

 

Take in and let them check it out, if you have a P0420 or a P0430 code if your check engine light is on, then it is definately a catalyst. If it is a noise issue, still take it in you have 8 years/80K on your cats for warranty.

 

It is not throwing a CEL.
