What you have heard is partially correct. The manufacturer of this vehicle is responsible for certain failed emission components when the vehicle has less than 80,000/100,000 miles, not the used car dealership/seller. This falls under the Federal Emission Component Warranty. The used car dealership which you purchased this Chevy Cruz from is more then likely going to refer you to the Chevy dealership. The Chevy dealership will need to conduct their own diagnosis to verify that the Catalytic Converter on this Chevy Cruz is in fact defective. You may be required to pay for this smog check diagnosis.
