So is there anything I can do, or do I just have to live with getting 28mpg? The car only has 50k miles, could it really be the traction battery already? And if so, would that be covered by warranty? 

Hello everybody! I just traded in my 2012 ct200h for a 2013 es300h. The problem is, I was expecting similar gas mileage but my es300h won't yield over 30mpg.  The car should get 40mpg combined.  

To start, I drive the car very gingerly, I try to keep the needle from ever going into the "power" zone. I over inflated the tires to 40psi. I do live in Wisconsin and the weather is in the 20's but that never affected my ct200h, I was regularly getting over 40mpg.

Is there an issue with my car? What can I do to get better gas mileage?
