Yesterday I noticed that some paint had come off my 6" round steps. I have heavy duty mud flaps. Now when I bought the truck, a 2014 Sierra All Terrain, I was very particular about having 'the least amount of chrome possible'. That's the reason why I went with the OEM black side steps (a friend had recomended against going aftermarket). I'm dissapointed that 18 months after I got the truck, these steps are already looking like crap because (as you can see in pic 2) paint adhesion isn't that great. There's bubbling visible and I am worried another big chip is coming off soon. And after next winter, all I will be left are some ugly rusted out side steps. Is this covered under waranty? Does anybody knows?
