what mode are you running in? Normal, Sport or Comfort? I have found I get much better mileage generally in comfort mode. Unless you use a very light foot electric will kick off when you start up. My average for 8000 miles is close to 27 in mixed driving. On a 22 mile commute at between 45 and 55 mph I usually get 30 to 34 mpg depending on wind and if I use ACC or not. The ACC generally will cut your mileage as it seems a bit aggressive with gas on/off in traffic. I have never seen 19 mpg ever on a trip in this car if over 5 miles. Running down to the corner and back, yes 19 mpg might happen.
