Well got my Palisade back, electronics are working, they could not say why it happened, it just did! As for the smell, could not smell anything other than car! Still no headrest but it does not smell. My dealer feels the only fix is new headrests or replacement ones.......OK Hyundai, I am wanting for my new headrests!Your trade is probably gone by now. From what I understand vehicles that are traded in are typically off of the lot within 24 hrs.
