How many converters it has does it only have one Cadillac converter

Hello, which engine do you have in your Fusion? Each "bank" of engine cylinders would have a catalytic converter. So, if you have a 4 cylinder, you have one. If you have a V6, you have 2. Some models also have an "underbody catalyst", which would make the potential 3. This would be visible under the vehicle. Are you having a concern that needs repair?
