The length of the limited warranty was determined when purchased,1 year. Catalytic converters, both direct fit and universal, are not warranted against physical damage caused by road hazards, damaged caused by a malfunctioning ECU system, or vehicles not properly repaired or maintained. Typically converter failures. and non-warranty issues, fall in to one of the following categories:
Physical damage due to corrosion, or from the converter contacting a large object on the road surface or “ballooning” of the converter body due to overheating of the substrate.
Contamination due to excessive oil consumption, internal coolant leak, or excessive carbon build up.
Overheating indicated by melted or broken substrate due to engine misfires or fuel trim issues which lead to excessive converter temperatures. This is indicated by a bluing or purplish coloring of the converter body.
Thermo quenching when a hot converter is cold quenched when driving through deep water or into deep snow.
Converter aging/lack of engine maintenance; cycles of damaging engine conditions will eventually deteriorate converter performance
