Black trim on my gray 2018 G80 turning gray and roof rails pealing

How long have you owned your G80?
It almost sounds like some paint defect that falls under the 3 year/60,000 mile coverage every Genesis model is under. Have you spoke to your dealer about it?
Can you share pictures of it here?

I have a 2020 G80 with less than 7500 miles and my trim is oxidizing. Dealer said they have a buffing compound they can use but may do it again, as they have this problem with others. They would only replace it after doing that, once. Then if the new product does the same, it would be up to me to pay for it.This car is garages.

I had the same issue with my 2018 Sport and ultimately had my dealer replace the drivers side window trim…. It takes more work than it should to keep this beautiful car looking great but now it’s settled in to needing a buff out with a microfiber cloth and some detailing spray.
