Check ALL of your fluids - Power Steering, Brake Reservoir and transmission. You could have a cooler line that is leaking.
Does your AC still work?

Is there a possibility that its from another vehicle?
- Something like apartment complex parking?

If no, look for drips off of components in your vehicle to isolate the source. You may need to wipe down the under carriage and start the car to see where the leak comes from. Use a flashlight to help find the drip(s).

Did they use an original equipment cat from the dealer or an aftermarket one? Aftermarket cats can cause more problems than they fix. There very few that I will personally install.

are they monitoring downstream O2 sensor data to see if the O2 sensor may be biased high? If the cat is doing its job the downstream O2 sensors will read a lower voltage. Tricking the vehicle into running rich or lean will cause this voltage to change ( unplugging a coil will cause the Downstream O2 to read high as the cat tries to burn off the extra fuel. Unplugging a fuel injector will cause the downstream O2 sensor to read low as extra air is being pushed thought the cats). Making sure the downstream O2 sensors are capable of switching should be part of the diagnostics.

Are you sure they replace the right cat? There are 5 different engine options for this car. If you let me know what engine you have I can let you know what bank is bank 1.

If check engine light is on. Get it scanned to find the problem code. They will do this at any auto parts store for free, It may be a bad 02 sensor. Get it scanned. A vehicle can fail a state-mandated smog test because a bad, or faulty, oxygen sensor. remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance. Good-Day!
