We acquired a 2012 Sonata Hybrid after looking at many options in this price/category.
the Sonata is comfortable to drive and ride in, fairly quite and gets OK (but not nearly the EPA MPG) gas mileage.
I've put about 2500 miles on it and it is averaging about 30 MPG in mostly in-town driving which is where it should be using the battery the most so I was expecting better MPG.
ANY in-town hill gives it a challenge as it tries to go from battery to motor.
Build quality is good so far.
Rear seats are comfortable.
Highway cruising is good.
Driver's seat is quite comfortable.
BlueLink system works well and easily links between my cell phone and the car's speaker system - it even automatically turns on the speakers when the phone gets an incoming call and the radio is off.
Passenger seat is low and does not have a way to raise it.
Seats are heated but the button does not default to "off" when the car is turned off which our SUV did and which we thought was better than the Hyundai.
The hybrid battery takes up a lot of space (which we knew) and also means that the rear seats will not fold down so if carrying larger items is on your agenda this hybrid will not work for you.
Most of the time this is not an issue but you should check.
Hyundai should be more honest with the MPG for the hybrid - improving the mileage was a key selling point and in this regard this vehicle is somewhat disappointing.
