Is there an issue that wouldn't show up on the scan tool or something I should look into to figure this out?
Tires are aired to specs. I've gotten all recommended maintenance. Driving habits haven't changed.
Thanks for any suggestions.

Any chance that your drop in mileage corresponds to a change in tires/wheels?
I personally observed changes in milage when I ditched the primacy tires and then again when I changed rims...
Almost everyone I know never replaces the original tires with another set of OEM tires.
Tires/wheels make a big difference in both handling and mileage in these cars.
