Catalytic converters rarely fail on their own. In most cases, another issue has caused the catalytic material to be contaminated, overheated, or damaged, leading to failure. The most typical failure comes from a failed primary/front O2 sensor, which cause the engine to run rich (reducing fuel economy), which also melts the catalyst. Replacing your failed catalyst without solving the root cause of failure will void any warranty and significantly reduce lifespan of the replacement catalyst. It is the customer's responsibility to diagnose and determine the root cause of a catalyst-related engine code. Before spending thousands of dollars on a new catalytic converter, make sure you have considered and investigated all other potential sources for your fault codes - oxygen (O2) sensors, cooling system, intake or exhaust leaks, fuel injection, vacuum, secondary air system, and other emissions-related equipment. Returns of this product are limited and may be subject to review before approval can be granted.
