Just an informational post for people who own a 2018 CX5 and who live in the state of Georgia. There is a known issue where the computer software used by many emissions stations in Georgia won't communicate with the software on a 2018 Mazda CX5. After experiencing this at two emissions stations, I drove to my Mazda dealership, and they informed me that this is a known issue and they sent me to an emissions station where they are currently sending all their 2018 CX5 vehicles that need emissions tests. The car passed with flying colors, but I'd check with your dealership regarding this issue before attempting to get an emissions test performed on a 2018 CX5 in GA.
