2017~2022 CX-5 Transmission and MPG

Hey Guys. Just got a 2018 CX-5 GT w/ 21K miles. First, only getting 15-17 MPG so far. Second item, getting strange sounds from front brakes when just warmed up for first time. Third and most troubling, Transmission shifting between first and second is slow. Going uphill is rough. I don't ride the pedal hard. I allow engine to build up slowly hoping for smooth shifts. Thats not happening.
Anyone having any of these issues, please share how you handled. My car is a Certified Pre-Owned with the (12) month warranty.

Your descriptions are somewhat vague. Regarding MPG, how many miles have put on it in arriving at those figures? How did you come by those figures? What kind of driving are you doing, stop-and-go in an urban center or something else? "Strange sounds" from the brakes? What kind? "Slow" and "rough" shifting are likewise vague.
 
Reset your A/B tripodometer, then check the Multi Information Display
