Overall, my 2009 Sonata GLS has been a dependable car for a very good price. I, like many others, have the dash/windshield creaking problem. This did not fully develop until around one year of ownership. The noise is present with every movement of the car (light acceleration, braking, undulation) not just over speed bumps or potholes. Call me OCD but it is so annoying, that I am about to dump the car at a loss. The dealer did try to fix the problem by re-seating the windshield but the noise is even worse after their "fix". If you can live with sub-par build quality and rattles, then the Sonata is a good deal. I am going back to a REAL foreign car like Honda or Toyota!
Power seat and steering wheel audio controls.
Folding side view mirrors and better build quality.
