The same with me. I have the 2016 CX-5 AWD GT 2.5 engine and I've never averaged more than 28 MPG on the highway (even going 60 MPH). I get 24-26 MPG around town and 26-27.5 MPG on the highway (less in mountainous or hilly areas). I only have 4,800 miles on it but when new, I drove it like an old lady and never let the tach go above 2K unless I was in 6th gear on the highway. On my car, keeping it below 2K while accelerating really didn't help the mileage. It takes much longer to get to 40MPH and the mileage is low until it finally gets into high hear. I now accelerate faster to 40MPH and my mileage is the same or better. I'm 61 years of age and I have always gotten higher mileage than the sticker said, so I was disappointed with not getting 30 MPG, especially when my 2011 Hyundai Sonata got 35-38 MPG. But I must admit that I love driving the CX-5 and I guess the few MPG lower doesn't amount to much money in the long run. I love the looks, the ride, the visibility, and the features of my CX-5 so I'll be happy if the car remains reliable.
