Both of mine were 5/22 builds. I can get more specific via build sheet if needed.
I know someone with a glacier blue 04/22 build date peeling as well.
After discussing with MANY techs, service advisors, and GM, the consensus belief is that since the ZR2 is the only GM truck (along with the AT4X) that has the chip guard 1/4 on the lower door panels, GM is not applying the proper primer prior to painting. If you look at my door peels, there is no primer on both truck doors. Also, there is an adhesion issue obviously due to either aluminum (if they are aluminum?) or because of the “rubberized” texture one mechanic told me is used. Who knows the true culprit, and I’m waiting to hear back about how GM is moving forward with my current black truck. I will let a body shop touch up the chip guard section of both doors as long as no door removal is needed. However, I’m worried about blending, specifically on the front fenders and rear truck bed where those two areas also have chip guard. If the peeling stops where it is currently, I’m ok with touching up my current bare metal areas and moving forward. BUT, will the peeling stop there? Over time, I doubt not. So frustrating that Chevy didn’t due the research on the rock chip painted doors to ascertain durability. Then again, maybe they did and said heck, it’s good enough
