Sorry you are having difficulty. My Dealer worked with me and my Corporate Rep. The only issue is that it just took so long to get the Headrests in. My wife noticed a slight odor yesterday, so I will give it a week or so to see if it is still a problem. All in all, it is no where near as bad as it was...however, I want zero smell. I will update after a week or so.Corporate is playing hard ball on us. They don't want to order all 7 new headrests even after doing the TSB 2 x with no results fixing anything. They say the dealer has to put in a request through Warranty and see if its approved. It better be approved. I have all 7 sitting in a bag in my dining room. I told the case manager i would send them to Hyundai and they can judge them for themselves and put them on their personal cars and drive them around and see how they like the smell.
