I have a 2017 Ford Focus and the Radio will constantly stay muted. I click on un-mute and it highlights it and click to turn it off but nothing happens. Anyone have any ideas?

I have a 2015 Ford Focus SE with a 4cyl 2.0L Flex Fuel Engine. When I do a full fill up it says 174 Miles until empty. I've cleared all of the Trip Info ect. I find it hard to believe a 4cyl Ford Focus would get 170 Miles till E. Do some city driving and highway driving and don't smash the gas. Anyone else had any kind of an issue like this? Also when I put on the Cruise control in the 70s sometime It will change randomly on it's own to Kilometers?
