I called them, but they said
I called them, but they said it was environmental. Mine is peeling in exactly the same place as yours. They said I would have to take it to a dealer. They said they would fix it, but was going to charge me almost $800.00. Mine is a 2016 GMC Denali. It too cost about what you paid for yours in 2016. It also is peeling on the front of the hood now. Dealer said it was because of a rock chip. I called BS on that one too. They just do not want to spend the money to fix them. This is happening to alot of people as you can see on this site. Do they really want to risk losing customers?
