Check that all services are up to date from the dealer you purchased it from/

fuel mileage is primarily based in driving habits. Make sure you are treating the car well.

Have system scanned for any codes.

421 is a bad cat converter. The exhaust leak will cause issues especially if it is before an o2 sensor. Have that leak fixed and see what happens
