Great overall car! However, beware engine of seizure.
Our family's 13' Sonata 2.0T Limited was a bullet proof reliable car for 80k miles until the engine seized and required rebuilding. The car was serviced regularly, so the engine seizure was quite the let down. However, Hyundai's warranty covered the cost of the tow, repair, and rental car as they replaced the known engine internals responsible for these failures. The repair process was hassle free overall, and the car is currently running like new once more.
Despite the rather glaring engine fault, the car has been great overall. It is fast, efficient, smooth, stylish, and well equipped for its price point.
The only other gripe is the longevity of the cheaper materials used in the construction of the interior. There is a particularly poor material used on the lower part of the steering wheel that has almost entirely peeled off, making for a bit of an unsavory look.
