 Purchased my 2008 Sonata GLS new in March, 2008. Since Day 1 there has been a rattle in the slider of the sunroof. Dealership 1 had car for one week in July,2008 to fix problem.... still rattled. Took it back, was ignored! Took vehicle to Dealership 2 and they got permission to re-do the sunroof this past January. They found clips were missing in sunroof. Problem still exists! Am now awaiting the same Dist. Mgr. who saw car in June of 2008. After taking car to three dealers like Hyundai asked, I am fed up with all the time spent taking car to dealers. Poor communications between dealerships and Hyundai. Will not recommend Hyundai ever to anyone!
