Decellaration Issue on 2014 Tacoma v/6 Automatic

I am new to this group. This is my first new Toyota Tacoma. I have noticed that it slows down extremely fast like the emergency brake is still on or like it is in a lower gear even though it is in drive. My prior vehicle was a Chevy Equinox that would roll forever when i let off on the gas pedal. What could cause this decellaration problem as it affects the gas milage, i'm sure.

beleive it or not , your truck is designed to save fuel when coasting . When you take your foot off the gas , the PCM tells the injectors to turn off . This is why your truck feels like its slowing down in comparison to older vehicles you have owned . Combine this with the converter remaining locked up and the transmission downshifting while going down hills can really be felt in the drivers seat .
Here is another post with another issue altogether but similar to yours

It's actually better for gas mileage because you are not using any fuel at all. The injectors are shut off. I also thought it was weird at first, but have gotten used to it.
