2003 Mazda Tribute

Warranty problem
2003 Mazda Tribute 6 cyl Four Wheel Drive Automatic 65000 miles

I purchaed the vehicle 2 years ago and this is the 3rd time the catalytic converter needs to be replaced. Shouldn't the Mazda dealer be looking at the coils or plugs before the 2nd converter was put in. I'm being told that this is going to cost $3000 to be fixed. Shouldn't the mechanics have done an analysis on why a 2nd catalytic converter was to be replaced in a short amount of time before it was installed.

I agree cats don't go bad unless a miss fire, rich fuel mixture or fuel contamination. Ask the factory rep. To meet you at shop to look into this problem.
