You sound very frustrated so
You sound very frustrated so you must have had a bad experience. Did you put a ceramic paint protection on your vehicle? It's always recommended because the FDA, not Hyundai, has removed the lead and polyurethane out of the paints. Looking at the fleet of cars on the road, it seems like you are over exaggerating the problem. Walking through parking lots I don't walk by and see bare metal on Hyundai's. I do hope you got your problem taken care of.
