ford mustang ecoboost premium after 13k miles and 8 months

Asked by Feb 08, 2017 at 11:51 AM about the 2016 Ford Mustang EcoBoost Premium

Question type: Maintenance & Repair

Hi I bought a brand mustang ecoboost premium on may 27 2016. Its so
painful when your car gets into issues within such a minimum time and miles
on it.
issue 1: yesterday I had my tank almost empty. the dashboard said 6 miles to
empty. I stopped at a gas station and started filling my gas. the pump turned
off after 12.5 gallons. generally I remember filling up untill 14.5 to 15 gallons
of gas. not sure where the room for another 2-3 gallons has gone!! I spoke
with a friend who drives a mustang ecoboost '16 and he said his tank may go
till 16 gallons at times. I checked the range as well. its showing as 275 miles
which earlier used to show me somewhere close to 315 miles. Also I feel like
the arrow on the gas gauge is below the F (which is supposed to be a little
further to F)
issue 2: I feel like the performance of my car is going down and not as it was
before. My friend who is been driving with me initially for around 3 months
took a long pause and resumed travelling with me recently and he said he
hear some weird sound with the engine.
issue 3: I hear some sound when I apply breaks as well.
issue 3: The gas mileage is getting bad day by day I dont know why. initially I
was driving real fast and slamming the throttle all the time. But when I spoke
with a friend he said I need to tune the engine initially for better performance.
That is when I started driving the car subtly. I remember seeing figures like
24.5 to 26 in the city but now a days I see gas which is hardly getting close
to 22. wanna let you know that I put regular gas and not premium.

Can someone kindly read my long post and please answer the questions.
Thank you so much.

Take it in to the dealer, let them run a diagnostic on it. I'm assuming you have it under warranty. A performance issue might indicate a problem with a sensor or even a module.

Turbo cars very picky about fuel. If you put bad gas in you will get bad performance and gas mileage. Try another station next fill up. You shouldn't need to tune the car. http://www.allfordmustangs.com/forums/2015-2-3l-ecoboost-talk/ Search the forum link above for your issues. Ask your questions on the forums. Should all be easy fixes and answers.
