catalitic converter replacement on 2002 Mazda Protege

since the car has under 100000 miles would this be a warrenty issue

Asked by for the 2002 Mazda Protege
You should check with your local Mazda dealership, but in 2002 I believe that most manufacturers only covered catalytic converters for 50,000 miles. At most it could be 80,000, so check with your local Mazda dealer.
