Hello everyone. I have been having some issues with my 2014 GT lately. It has felt sluggish lately and the other day the check engine light came on with error code P0430 “Catalyst System Efficience Below Threshold Bank 2”. I had my local mechanic tell me that I need to have the catalytic converters replaced but what could be causing them to fail in the first place? I don’t want to buy new cats and have them go out as well. The car only has 80,000 miles on it. Has anyone else had this problem before?
