thank you for this post, I am so frustrated with GM as I am having the same problem. black 2014 gmc all terrain front metal bumpers paint is chipping off in flecks about dime size or better. Local Dealer said tough and im sol. Dealer sold it to me said bring it back and he would see what he could do but it sounds like rock chips. I've had 30 trucks never had a bumper look like this. Anyone find resolution to this? What a sad representation by gm.
