My Palisade also smells, and I've had it since Oct 2020 (7-months). I've had it to dealer six times and treated, but it still smells. They replaced two to the six headrests but won’t replace the rest? I also filed a complaint with Hyundai, but they never gave a solution or timeline to fix the issue! Is there a lemon law or class action lawsuit available? It degrades the value of the vehicle and may limit its use for some. Finally, there is a health and safety concern! What is causing the smell and is it toxic, cancer causing or harmful. You and your family are in a confined space and may have long-term exposure to harmful outgassing while traveling. I wish someone would do air sample test!!
