 Major problems from the start. Navigation/radio total failure. Gear shift stopped working-froze in park.  Recently air bag malfunction. Now the engine failed.  Burns oil and rod knock with no warning. Need a new engine but Hyundai is initially refusing to back its warranty because I cannot product every oil/filter receipt (sometimes had private mechanic change). Research has led me to an investigation into class action suit for engine failure by Chimicles & Tikellis.  Good to know that I am not alone.  Hyundai is like the cable company - once you are a customer they don't care.  Should have gone with Honda or Toyota and will do so going forward.
