Check the fuel filter or a possible leak in the fuel line or vacuum lines.your exhaust could be clogged causing too much back pressure

far as the review says the mileage should not falter since it is new as you said.
are the causes of a poor mileage in a car:-
Inflated Car Tires
tires that are improperly inflated create significant road resistance and drag
on a moving car. A car engine has to work harder to propel a car forward due to
this increased tire/road resistance. This resistance chips away at a car's gas
dirty air filter impedes air flow into a car's engine, a process that disrupts
normal engine combustion and makes it less efficient. This causes a reduction
in both engine performance and gas mileage.
plugs are responsible for igniting a car's air/fuel mixture, an event that
causes a mini explosion inside a car's engine cylinders. Bad or dysfunctional
spark plugs don't fire, or ignite, properly; thus, they affect engine
combustion negatively, which in turn negatively affects gas mileage.
a car to be at its most fuel efficient, its oxygen sensors, small and
electronically operated, automatically adjust a car's air/fuel mixture and have
to be functioning properly. Bad oxygen sensors cause abnormal air/fuel mixture
ratios, a condition that results in poor gas mileage and poor vehicle
car's fuel injection system is responsible for injecting precise amounts of
fuel into a car's engine cylinders, where it is combined with air and ignited.
For a car to perform properly, a specific amount of fuel has to be injected by
each fuel injector into each engine cylinder. A leaky fuel injector wastes fuel
by leaking it outside the engine and reducing the amount of fuel that makes it
into the engine. This results in wasted fuel and reduced gas mileage.
It is suggested to start with a code scanner to find out if there are any stored fault codes in your car.
