It is unfortunate that my reflective material has started to melt inside the fog light housing. I added the oem fogs and haven't had them on long. Does warranty cover this considering it is an oem part?
If they are a real GM OEM accessory and you are in the 3 year 36,000 mile bumper to bumper yes they are covered. Otherwise I don't think they are covered. If you installed them yourself I think you just have to prove they are genuine OEM GM accessory or I guess they could tell by the part numbers on the fogs. All genuine OEM GM accessories are covered under the bumper to bumper.
