 After almost decades of owning premium / luxury cars, I made the regrettable decision to buy a Hyundai. All my friends and family were skeptical. I have spent the past several months working with dealers and HMA Consumer Affairs to address the problems. Every time they tell me they DO NOT see the problems. Is anyone else having these problems? The whole experience has been extremely disappointing. 1. Rattling / grinding sound when driving at lower gears 2. Jerky transmission shifts 3. Squeaking / cranking sound from the rear seat when driving 4. Loud rumbling noise when starting the car 5. Vibrations while driving 6. Tires worn out at 25k miles 7. Cruise control does not work
