2023 Tucson Hybrid Limited owner...I just noticed an interesting panel on the roof behind the shark fin antenna. Does anyone know what it is? It looks like it should pop up (for some reason), but I can't figure out what the heck it is. BTW, I've owned 10 cars (MGB, Charger, Fords, Toyotas - all bought new), and this is my third Hyundai. It's by far the best car I've ever owned.
